chore: stash in-progress test edit

Captures the modified state of test_api_parse_persists.py so the in-progress test work is preserved on the claims-unique-fix branch as the sp-prefixed worktrees are cleaned up. The .venv and .gitignore_local noise in the working tree are intentionally left untracked.

 ## Auth gate (SP24)
 Every router declared in `backend/src/cyclone/api_routers/` **must** carry `dependencies=[Depends(matrix_gate)]` at the `APIRouter(...)` declaration — not on each individual endpoint. The gate lives at `backend/src/cyclone/auth/deps.py:107` and the role matrix is at `backend/src/cyclone/auth/permissions.py`. The roles are `admin / user / viewer`; `matrix_gate` returns 401 when there's no session and 403 when the role is below the endpoint's required role. When `AUTH_DISABLED` is True (conftest autouse fixture flips it; `CYCLONE_AUTH_DISABLED=1` in prod-by-mistake), the gate short-circuits to a synthetic admin — see the SP24 spec for the threat-model implications. New routers get the gate by default; the auth-aware convention is `router = APIRouter(dependencies=[Depends(matrix_gate)])`.

 ## Auth-aware spec template (SP24)
 The threat-model section in the canonical SP-N spec template (`## 1. Scope`, second-to-last bullet) used to read "no second party to authenticate; no second host to harden against." **That phrasing is stale as of 2026-06-23** — the auth work landed in `main` and every backend endpoint requires login. New specs should instead state the auth boundary explicitly: "the auth boundary is HTTP (login required, bcrypt + HttpOnly session cookie); file-system threats remain the local-only threat model (SQLCipher at rest, macOS Keychain). SP23 changes the threat model to LAN-bound remote operator."

 ## Auth flag (SP24)
 The autouse `conftest.py` fixture at `backend/tests/conftest.py` flips `cyclone.auth.deps.AUTH_DISABLED = True` for the entire test session, so every test runs without a login round-trip. **Any new test that reads `cyclone.auth.deps.AUTH_DISABLED` directly will see `True`** — that's the test-suite reality, not a production reality. If you need a test that exercises the real gate, import `from cyclone.auth.deps import matrix_gate` and call it directly with a `Request` whose `state` carries a real session, or flip the flag back inside the test and reset it on teardown. The startup WARNING (`backend/src/cyclone/__main__.py`) is silent in tests by default because the conftest sets the flag before `bootstrap.run()` is called via `import`.

 # CLAUDE.md
 This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
 ## What this is
 Cyclone is a self-hosted X12 EDI claims-management suite for a single billing office (Colorado Medicaid currently). It parses 837P professional claims and 835 ERA remittances (X12 005010X222A1 / 005010X221A1) and also handles 999, TA1, 270, 271, and 277CA. Local-only by design: binds to `127.0.0.1`, requires login (auth boundary is HTTP; bcrypt + HttpOnly session cookie; first admin bootstrapped from `CYCLONE_ADMIN_USERNAME` + `CYCLONE_ADMIN_PASSWORD` env vars; see SP24 spec for the full posture), no internet exposure.
 Stack: one Python process (FastAPI + uvicorn, port 8000) + one Node process in dev (Vite, port 5173). The authoritative state is a single SQLite file at `~/.local/share/cyclone/cyclone.db` (or SQLCipher at the same path when the macOS Keychain entry + `sqlcipher3` are both present).
 For the day-1 architecture read, see `docs/ARCHITECTURE.md` (process topology, module map, store facade, parser pipeline, pubsub). For the what-it-does read, see `docs/REQUIREMENTS.md` (FRs + NFRs + DoD).
 ## Install
 ```bash
 # Backend (Python 3.11+)
 cd backend
 python -m venv .venv
 .venv/bin/pip install -e '.[dev]'
 # Frontend (Node 20+)
 cd ..
 npm install
 ```
 Optional backend extras: `pip install -e '.[sqlcipher]'` (encryption at rest, SP12) and `pip install -e '.[sftp]'` (real SFTP, SP13).
 ## Dev (two terminals)
 ```bash
 # Terminal 1 — backend
 cd backend
 .venv/bin/python -m cyclone serve         # default 127.0.0.1:8000
 # CYCLONE_PORT=... overrides port; CYCLONE_RELOAD=1 enables uvicorn --reload
 # Or: .venv/bin/uvicorn cyclone.api:app --reload --port 8000
 # Terminal 2 — frontend
 npm run dev                                # Vite on http://localhost:5173
 ```
 Vite proxies `/api/*` to the backend at `http://127.0.0.1:${CYCLONE_PORT:-8000}` so relative-URL fetchers (the live-tail NDJSON streams in particular) resolve through the same origin. Override the backend port with `CYCLONE_PORT` in the frontend terminal too.
 Create `.env.local` at the repo root with `VITE_API_BASE_URL=http://127.0.0.1:8000`. Without it, the UI runs against the in-memory zustand store and real EDI parsing is disabled.
 ## Test
 ```bash
 # Backend — full suite
 cd backend && .venv/bin/pytest
 # Backend — one file
 cd backend && .venv/bin/pytest tests/test_api_999.py -v
 # Backend — one test by node id
 cd backend && .venv/bin/pytest tests/test_api_999.py::test_parse_999_endpoint_happy_path -v
 # Frontend — full suite
 npm test                                    # alias for `vitest run`
 # Frontend — one file

 # Frontend — typecheck
 npm run typecheck
 # Frontend — build (tsc -b + vite build)
 npm run build
 # Frontend — lint
 npm run lint
 ```
 **Conventions** (full detail in `.superpowers/skills/cyclone-tests/SKILL.md`):
 - Backend tests live under `backend/tests/test_*.py`. Two flavors: `test_api_<topic>_<verb>.py` (FastAPI integration via `fastapi.testclient.TestClient`) and `test_<module>_<behavior>.py` (pure-unit). Autouse `conftest.py` points `CYCLONE_DB_URL` at `tmp_path/test.db`, calls `db._reset_for_tests()` + `db.init_db()`, and wires a fresh `EventBus` onto `app.state`.
 - Prodfiles (real EDI samples under `docs/prodfiles/<source>/`) are never read directly from a test — copy to `backend/tests/fixtures/<descriptive-name>.txt` first and reference as a module-level `Path` constant. The `fixtures/` dir is flat (no per-test subdirs).
 - Frontend tests are siblings: `useFoo.ts` → `useFoo.test.ts`, `ClaimDrawer.tsx` → `ClaimDrawer.test.tsx`. Setup is `// @vitest-environment happy-dom` plus `(globalThis as { IS_REACT_ACT_ENVIRONMENT?: boolean }).IS_REACT_ACT_ENVIRONMENT = true;`. Mock the API at the module boundary with `vi.mock("@/lib/api", ...)`; stub fetch with `vi.stubGlobal("fetch", vi.fn().mockResolvedValue(...))`. `vitest.config.ts` sets `VITE_API_BASE_URL=http://test.local` so the `api` module doesn't throw `notConfiguredError` before the mock fires.
 - Time-sensitive tests: frontend uses `vi.useFakeTimers()` + `vi.setSystemTime(...)` + `vi.advanceTimersByTime(ms)`. Backend passes explicit `datetime(...)` values. Don't add `await new Promise((r) => setTimeout(r, N))` — it's the legacy flaky pattern.
 ## Project-scoped skills (`.superpowers/skills/`)
 Cyclone ships 8 skills under `.superpowers/skills/`. They auto-load by description match — no slash command needed. **Read the relevant skill before touching the matching subsystem.**
 | Skill | Owns |
 |---|---|
 | `cyclone-spec` | The SP-N spec → plan → implement → merge flow (branch shape, file paths, commit prefixes, PR title, merge shape). |
 | `cyclone-tests` | pytest + vitest fixture patterns, prodfiles drop-in rule, determinism rules. |
 | `cyclone-edi` | EDI parser/validator conventions (837P/835/999/270/271/277CA/TA1, R-codes, CAS mapping). |
 | `cyclone-tail` | Live-tail streaming wire format and the `useTailStream` + `useMergedTail` + `TailStatusPill` hook triplet. |
 | `cyclone-store` | `CycloneStore` facade, write-paths, pubsub event contract, SP21 split map. |
 | `cyclone-api-router` | FastAPI router conventions (`api_routers/`, `api_helpers.py`), response/error-envelope shapes. |
 | `cyclone-frontend-page` | React page conventions (TanStack Query `use<X>` hook, drawer, URL state, sibling test). |
 | `cyclone-cli` | CLI subcommand conventions (`cli.py`, exit codes, smoke tests). |
 ## The SP-N increment flow
 Every feature ships as a numbered **SP-N increment**: spec → plan → implementation branch → single atomic merge into `main`. As of the last backfill, SP numbers are used through **SP22**; **SP23** is reserved for the Ubuntu + Docker + RBAC product fork (`docs/superpowers/specs/2026-06-22-cyclone-ubuntu-docker-deployment-design.md`, awaiting user decision); the next free increment is **SP24**. Read `cyclone-spec` before starting a new one. Non-negotiable shape:
 - **Branch:** `sp<N>-<short-kebab-topic>` (e.g. `sp22-line-reconciliation`).
 - **Spec path:** `docs/superpowers/specs/YYYY-MM-DD-cyclone-<topic>-design.md`, header `Status: Draft, awaiting user sign-off`, sections `Scope / Decisions / …`. Specs contain zero code blocks.
 - **Plan path:** `docs/superpowers/plans/YYYY-MM-DD-cyclone-<topic>.md`, header per `superpowers:writing-plans` with `Goal / Architecture / Tech Stack / Spec` metadata + numbered `- [ ] Step N:` tasks.
 - **Commit prefixes:** `feat(sp<N>): …`, `docs(spec): …`, `docs(plan): …`, `merge: SP<N> <topic> into main`.
 - **PR title:** `SP<N> <Topic>` (matches the merge-commit subject).
 - **Merge shape:** single atomic merge commit. **No squash** (collapses the audit trail) and **no rebase** (rewrites the SHAs the review was performed against). The SP-N merge commit *is* the record of the increment landing.
 The matching skill to load alongside `cyclone-spec` depends on the subsystem the SP-N touches (see the "Related skills" section at the bottom of each skill file).
 ## Live-tail wire format
 The Claims, Remittances, and Activity pages stay current without manual refresh. The backend publishes an internal event on every store write, the page opens a streaming HTTP connection to the matching `/api/<resource>/stream` endpoint, and new rows append to the table the moment they hit the database.
 Endpoints (all accept the same query params as their non-streaming counterparts; `Content-Type: application/x-ndjson`):
 | Method | Path | Subscribes to | Default sort |
 |---|---|---|---|
 | GET | `/api/claims/stream` | `claim_written` | `-submission_date` |
 | GET | `/api/remittances/stream` | `remittance_written` | `-received_date` |
 | GET | `/api/activity/stream` | `activity_recorded` | `-timestamp` (limit 50) |
 Wire format: one JSON object per line, `{"type": ..., "data": ...}`. The first batch is the **snapshot** of currently-known rows, then `snapshot_end` with the count, then the **live** events. Known types: `item`, `snapshot_end`, `heartbeat` (keeps the connection alive on idle — clients flip to `stalled` after 30s of total silence), `item_dropped` (rare), `error`.
 Status pill states (rendered by `<TailStatusPill>` in `src/components/TailStatusPill.tsx`): `live` (success), `connecting` (warning), `reconnecting` (warning), `stalled` (destructive, ↻ Reconnect button), `error` (destructive, ↻ Reconnect button), `closed` (destructive). Backoff on error: `1s → 2s → 4s → 8s → 16s → 30s` capped. `STALL_TIMEOUT_MS = 30_000` in `src/hooks/useTailStream.ts:53`. Heartbeat interval is `CYCLONE_TAIL_HEARTBEAT_S` env var, default 15s.
 Frontend triplet for any live page: `use<X>(params)` (initial fetch) + `useTailStream(resource)` (opens the NDJSON stream, drives backoff/stall) + `useMergedTail(resource, baseItems, filterFn?)` (merges snapshot + tail, dedup'd by id). The subscription lives on the page, not inside the data hook — see `cyclone-frontend-page` for why.
 ## Backend at a glance
 `backend/src/cyclone/` is a single namespace. The two largest files are `api.py` (~3,548 LOC, the only large file) and `store.py` (~2,423 LOC, the `CycloneStore` facade — SP21 is in flight to split it into a `cyclone/store/` subpackage; the public API stays unchanged). Subpackages: `api_routers/` (acks, admin, health, ta1_acks), `clearhouse/` (Clearhouse + SftpClient), `edi/` (filenames), `parsers/` (X12 transaction parsers + models + validators + serializers), `workflow/` (placeholder for future sub-project 6).
 The store is the only read/write surface for the database; every mutating endpoint goes through it. All persistence flows through SQLAlchemy sessions via `db.SessionLocal()()`. SQLAlchemy ORM models live in `db.py`; 12 SQL migrations under `migrations/` (0001_initial through 0012_backups) are walked in order by `db_migrate.py`.
 The parser pipeline is a 5-stage `tokenize → segmentize → model → validate → write_to_store` flow used for every inbound X12 type. Per-transaction parsers: `parse_837.py`, `parse_835.py`, `parse_999.py`, `parse_ta1.py`, `parse_270.py`, `parse_271.py`, `parse_277ca.py`. Each has a matching Pydantic model module (`models.py`, `models_835.py`, …) and a writer (`writer.py` / `writer_835.py`). The 837P serializer (`serialize_837.py`) is the byte-faithful outbound counterpart used by both single-claim download (`/api/claims/{id}/serialize-837`) and the bulk rejected-resubmit bundle (`/api/inbox/rejected/resubmit?download=true`).
 The pubsub is `cyclone.pubsub.EventBus` — an in-process async fan-out broker. Publishers call `publish(kind, payload)`; subscribers receive via an async iterator. If a subscriber's per-kind queue is full, the oldest event is dropped so a slow consumer can't stall the producer. Bus is single-event-loop only (matches FastAPI/uvicorn).
 Config: `config/payers.yaml` is the on-disk source for providers / payers / clearhouse, schema-validated at boot against a Pydantic model. Reload with `POST /api/admin/reload-config`. Original in-code `PAYER_FACTORIES` dict in `cli.py` is kept as a fallback for ad-hoc testing.
 Secrets live in the macOS Keychain (via `keyring` + `cyclone.secrets`): SQLCipher key (service `cyclone`, account `cyclone.db.key`), SFTP password, backup passphrase. No secrets on disk in plaintext.
 ## Frontend at a glance
 `src/` is React 18 + TypeScript + Vite. Routes register in `src/App.tsx` (11 pages, all under a `<Layout>` route wrapper). Pages are pure renderers — every page pairs with a `use<X>` data hook in `src/hooks/` and renders a `<PageHeader>` + a table/list/KPI grid. Drawers (`ClaimDrawer/`, `RemitDrawer/`, plus the new `ProviderDrawer/` and `AckDrawer/`) are mounted by the page and their open/close state is mirrored to the URL via `useDrawerUrlState` so deep-links round-trip. Drill-stack navigation is provided by `<DrillStackProvider>` in `src/components/drill/`.
 State split: **server state** in TanStack Query (`@tanstack/react-query`); **ephemeral client state** in Zustand (`useTailStore` for live-tail append, plus the drill stack). The live-tail store is FIFO-capped at `TAIL_CAP = 10_000` per slice (`src/store/tail-store.ts:28`); `claims` and `remittances` are key-by-id with first-write-wins dedup, `activity` is an append-only array.
 UI primitives in `src/components/ui/` are Radix-backed (`button`, `dialog`, `table`, `select`, `pagination`, `empty-state`, `error-state`, `filter-chips`, `skeleton`, `input`, `label`, `card`, `badge`, `skip-link`, `claim-state-badge`). Don't import a new UI library without discussion.
 Path alias `@/` → `src/`. Configured in `vite.config.ts`, `vitest.config.ts`, and `tsconfig.app.json`.
 ## CLI
 ```bash
 # Parser

 ```
 Exit codes are documented per subcommand in `cyclone-cli` — `0` for success, `2` for file-level failure, `1` for unexpected exceptions.
 ## Things that are easy to get wrong
 - **`VITE_API_BASE_URL` matters.** With it empty, every `api` method throws `notConfiguredError()` and the UI falls back to the in-memory zustand store — parses are disabled and the live-tail streams never open.
 - **Prodfiles vs fixtures.** Tests must reference `backend/tests/fixtures/<name>.txt`, not `docs/prodfiles/<source>/<file>.txt`. The prodfiles dir is the source-of-truth archive; the fixtures dir is the stable test surface.
 - **SP-N merge shape.** No squash, no rebase. The merge commit *is* the audit trail. Squash collapses the per-commit history and breaks the SP-N audit trail.
 - **Don't put domain logic in JSX.** Conditional renderings, table sorting, and KPI math all belong in the `use<X>` hook or a pure helper under `src/lib/`.
 - **Don't open a drawer via local `useState`.** Use `useDrawerUrlState()` so the URL is the single source of truth — deep-links and reload-restore depend on it.
 - **Don't call `useTailStream` from inside a `use<X>` hook.** The subscription lives on the page so the lifecycle ties to whoever mounts the hook, not to whoever happens to call it.
 - **The store facade.** The public API of `cyclone.store` is preserved through SP21's split — call through the facade, not directly into the underlying modules.
 - **Encryption is optional, not required.** When the Keychain entry is missing **or** `sqlcipher3` is not installed, the DB falls back to plain SQLite. Don't fail boot on missing encryption.
 - **Local-only by design.** The backend binds to `127.0.0.1`, requires login (bcrypt + HttpOnly session cookie; see SP24 spec), and the threat model is still a stolen/imaged drive — SQLCipher at rest and the macOS Keychain handle that. The auth boundary is the HTTP layer; the file-system posture is unchanged. Don't add internet exposure. Don't disable auth without an explicit `CYCLONE_AUTH_DISABLED=1` env var (the escape hatch logs a WARNING at boot).

 ## Authentication
 Cyclone ships with username/password authentication and three predefined roles.
 **Roles:**
 | Role     | Can read | Can write (upload, parse, reconcile) | Can manage users |
 | -------- | -------- | ------------------------------------ | ---------------- |
 | `viewer` | ✅       | ❌                                   | ❌               |
 | `user`   | ✅       | ✅                                   | ❌               |
 | `admin`  | ✅       | ✅                                   | ✅               |
 **Bootstrap.** On first start, set `CYCLONE_ADMIN_USERNAME` and
 `CYCLONE_ADMIN_PASSWORD` (min 12 chars) in your environment. Cyclone creates the
 first admin automatically. On subsequent starts these env vars are ignored, so
 rotating the bootstrap password doesn't affect an already-seeded admin — use the
 CLI below to reset it. When running via `docker compose`, both vars are
 required: compose refuses to start with a clear error if either is missing.
 **CLI.** Manage users from the command line:
 ```
 python -m cyclone users create alice --role user --password 'hunter2hunter2'
 python -m cyclone users list
 python -m cyclone users disable alice
 python -m cyclone users reset-password alice
 python -m cyclone users set-role alice --role admin
 ```
 **Login.** Browse to `http://localhost:5173` (dev) or `http://localhost:8081`
 (Docker), sign in on the `/login` page, and you'll be redirected to the
 dashboard. Sessions are stored server-side in SQLite with a 24-hour sliding
 expiry — every authenticated request refreshes the TTL, so an active user
 never gets logged out.
 **Dev escape hatch.** Set `CYCLONE_AUTH_DISABLED=1` to bypass auth entirely
 (the backend auto-grants admin on every request). **NEVER set this in

 # Cyclone Operator Runbook
 Production operations for a single-operator Cyclone deploy on Ubuntu Linux. Assumes the box was bootstrapped via `scripts/cyclone-init.sh` and the stack is up via `docker compose up -d`.
 ## Daily
 - [ ] Confirm the host healthcheck cron hasn't emailed. It pings `http://localhost:8080/api/health` every 5 minutes.
 - [ ] `docker compose ps` — both services `healthy`.
 - [ ] `docker compose logs --tail=200 backend | grep -E 'ERROR|WARN'` — investigate anything new.
 ## Weekly
 - [ ] `curl -fsS http://localhost:8080/api/admin/audit-log -b cookies.txt | jq '.events[] | select(.event | test("login_failed|backup.failed"))'` — review failed logins + backup failures.
 - [ ] Confirm `docker compose exec backend ls -la /var/lib/cyclone/backups/` shows recent `.bin` files (within 25h of now).
 ## Quarterly
 - [ ] Rotate the SQLCipher / cookie-signing key:
  ```bash
  bash scripts/cyclone-init.sh --force   # overwrites /etc/cyclone/secrets/db.key
  docker compose restart backend          # picks up the new key
  ```
  Old `.bin` backups become unreadable after this; export them first if you need to keep them.
 ## As needed
 - **Add an operator.** Log in as admin → `/admin/users` → Create user. Roles: `admin` / `user` / `viewer`.
 - **Reset a password.** Admin UI → Users → Reset password, OR `docker compose exec backend python -m cyclone admin reset-password --username <name>`.
 - **Restore from backup.** Admin UI → Backups → pick the snapshot → Initiate restore → Confirm. The backend will restart automatically.
 - **Roll back the code (not the schema).** `TAG=0.0.9 docker compose up -d`. The previous image stays in the local Docker cache for one cycle.
 - **Pull a new `:stable`.**
  ```bash
  cd /opt/cyclone
  docker compose pull
  docker compose up -d
  docker compose logs -f backend | head -200   # verify migrations + healthcheck
  ```
 - **Off-box backup copy.** The operator is expected to rsync `/var/lib/docker/volumes/cyclone_backups/_data/` to an external drive or NAS nightly. The `.bin` files are already encrypted; the destination doesn't need its own encryption.
 - **Inspect the DB.** `docker compose exec backend sqlite3 /var/lib/cyclone/db/cyclone.db ".tables"` (works only if SQLCipher key is on disk; the in-process decrypt happens via the cyclone backend).
 ## Annual
 - [ ] Rotate the admin password (force re-login for everyone).
 - [ ] Audit the `/etc/cyclone/secrets/` directory permissions — should be `chmod 600 root:root`.
 - [ ] Review the audit log for stale admin sessions.
 ## Emergency
 - **Backend won't start.** `docker compose logs --tail=300 backend`. Look for migration failures (rerun is safe — migrations are forward-only), SQLCipher key mismatch (`PRAGMA key` failure), or port collisions.
 - **Frontend won't serve.** `docker compose logs --tail=100 frontend`. Usually nginx config drift; `docker compose restart frontend`.
 - **Both unhealthy after a host reboot.** Docker may have come up before the named volumes did. `docker compose down && docker compose up -d`.
 - **Suspected key compromise.** Rotate immediately (see Quarterly above). All active sessions are invalidated.

 # as root inside the container; Docker's user-namespace remapping is
 # the recommended host-level isolation. The `cyclone` user is created
 # above and survives only so file ownership in bind mounts stays
 # consistent. To harden later: install gosu + add an entrypoint script
 # that does `chown -R cyclone:cyclone /var/lib/cyclone/... && exec gosu

 -----------
 - ``users create USERNAME --role {admin,user,viewer} [--password PW]``
  Create a user. If ``--password`` is omitted, prompts (with

 - ``users list`` — tab-separated ``id / username / role / state``.

 * 1 — validation error (unknown username, duplicate username)
 * 2 — usage error (missing arg, bad role, short password, unknown

 # =============================================================================
 #
 # **What.** The four listeners below (``_match_before_insert``,
 # ``_cas_before_insert``, ``_slp_before_insert``, ``_lr_before_insert``)
 # run on every INSERT of a ``Match`` / ``CasAdjustment`` /
 # ``ServiceLinePayment`` / ``LineReconciliation`` row. They look up the
 # parent ``Claim`` / ``Remittance`` and copy its ``batch_id`` (and
 # ``remittance_batch_id``) into the new row's composite-FK column.
 #
 # **Why.** After migration 0014, every child table has a composite FK to
 # its parent: ``(batch_id, claim_id)`` for Match / LineReconciliation and
 # ``(remittance_batch_id, remittance_id)`` for CasAdjustment /
 # ServiceLinePayment. Both sides are ``NOT NULL`` at the SQL level, so
 # every insert must supply ``batch_id``. Application code that creates
 # these rows usually has the parent ``claim_id`` / ``remittance_id`` in
 # scope (often as a string) but does not always have ``batch_id``
 # readily available — the batch is created elsewhere in the same ingest
 # transaction, or the parent is fetched by id alone. Threading
 # ``batch_id`` through every call site would be error-prone. The events
 # solve this transparently: caller passes the parent id as before, and
 # the event fills in the batch side.
 #
 # **Lookup order** (preferred-to-fallback, to minimize round-trips):
 #   1. ``session.new`` — pending parents added in this transaction
 #      (covers the common ingest/match flow where parent + child are
 #      added in the same session).
 #   2. ``session.identity_map`` — already-persisted parents loaded
 #      earlier in this session.
 #   3. ``session.execute(select(...))`` — DB query as a last resort.
 #      ``autoflush`` is OFF on our ``SessionLocal``, so this won't
 #      trigger an unintended flush of ``session.new``.
 #
 # **When it fails.** If the parent is in none of the above (e.g. the
 # caller passed a parent id that was never added to the session and is
 # not in the DB), the column stays NULL and the INSERT fails with
 # ``IntegrityError: NOT NULL constraint failed: <table>.batch_id`` (or
 # ``remittance_batch_id``). The error message is misleading — it looks
 # like the column was forgotten, not that the parent id was wrong.
 # Workarounds:
 #   * If the parent exists in another session, ``session.add(parent)``
 #     first (or use ``session.merge(parent)``) so the lookup finds it
 #     in ``session.new`` / ``session.identity_map``.
 #   * If you have the parent object in scope and know its ``batch_id``,
 #     set ``child.batch_id = ...`` explicitly — the event only fills
 #     in when the column is None, so explicit values win.
 #   * If the parent is on a different connection entirely, populate the
 #     column by hand before ``session.add(child)``.
 #
 # **Idempotency.** The events only act when ``target.batch_id is None``
 # (or ``remittance_batch_id``). Application code may explicitly set
 # either column — e.g., a bulk-loader that already has batch_id in hand
 # skips the lookup.
 #
 # **Scope.** ``propagate=True`` so subclasses of these mappers (in
 # tests, mainly) inherit the listeners. Production code does not use
 # mapper inheritance for these tables.

 """CLI subcommand: ``python -m cyclone seed``.
 Populates the local DB with a deterministic batch of sample claims
 plus matching activity events, so the Dashboard / Claims / Activity
 Log pages have something to render in a fresh dev environment.
 This is a dev-only convenience — the production DB never sees this
 command (no ``[env: dev]`` gate, but it's never wired into any
 container image). It writes rows with a recognizable batch id prefix
 (``SEED-``) so ``--reset`` can clean them up without touching real
 ingested data.
 Why the data shape is hand-rolled here
 --------------------------------------
 The ``Claim`` ORM table stores its billing_provider / payer /
 subscriber / service_lines payloads in a ``raw_json`` blob that the
 read path (``store.to_ui_claim_from_orm``) parses back into the UI
 shape. Mirroring the 837 parser's structure keeps the UI rendering
 identical to a real ingestion — wire format parity, not shortcuts.
 Activity rows are similar: ``payload_json`` carries the message
 string the Dashboard's activity card shows.
 Subcommands
 -----------
 ``python -m cyclone seed``              — insert the default batch.
 ``python -m cyclone seed --count N``    — insert N claims (default 96).
 ``python -m cyclone seed --reset``      — wipe previously-seeded rows
                                          first, then insert a fresh batch.
 ``python -m cyclone seed --status``     — print row counts without
                                          inserting anything.
 Exit codes
 ----------
 * 0 — success (or already seeded and not asked to reset).
 * 1 — DB error during insert.
 * 2 — usage error (bad flag value).
 The command is idempotent: re-running without ``--reset`` is a no-op
 once a seed batch exists. This keeps ``cyclone``-driven boot scripts
 safe to re-run.

 # Cyclone — Technical Architecture
 > **Day-1 read for engineers joining Cyclone.** This is the top-level technical design: how the system fits together, what the boundaries are, and why it looks the way it does.
 >
 > **Companion docs:**
 > - **Requirements:** [`docs/REQUIREMENTS.md`](REQUIREMENTS.md) — what Cyclone does (FRs + NFRs + DoD + traceability).
 > - **Specs:** [`docs/superpowers/specs/`](superpowers/specs/) — design specs per sub-project (22 specs).
 > - **Plans:** [`docs/superpowers/plans/`](superpowers/plans/) — TDD-shaped implementation plans per sub-project (27 plans).
 >
 > **Scope of this doc:** architecture and design. The spec files own per-SP design; the plan files own the task order. This doc explains the *whole* — the boundaries between modules, the data flow across them, the lifecycle of an inbound file from upload to reconciled claim.

 ## 1. System overview
 Cyclone is a self-hosted X12 EDI claims-management suite for a single billing office. The first deployment target is Colorado Medicaid (one operator, one trading partner). The system is local-only on purpose: the backend binds to `127.0.0.1` and requires login (bcrypt + HttpOnly session cookie). The threat model is still a stolen or imaged drive, not a remote attacker — SQLCipher at rest and the macOS Keychain handle that. The auth boundary is the HTTP layer; the file-system posture is unchanged. The SP23 product fork changes the threat model to "remote operator on LAN."
 Cyclone processes three X12 transaction pairs end-to-end:
 | Inbound | Outbound | Use |
 |---|---|---|
 | **837P** (005010X222A1) | 837P (resubmit) | Professional claim submission, acknowledgment tracking |
 | **835** (005010X221A1) | — | ERA remittance ingestion, auto-reconciliation |
 | **999 / TA1 / 270 / 271 / 277CA** | 999 (after submit) | Acknowledgments, eligibility, claim status |
 The authoritative store is a single SQLite file at `~/.local/share/cyclone/cyclone.db` (or, with `sqlcipher3` installed and a Keychain entry, a SQLCipher-encrypted file at the same path). Every claim, remittance, audit event, and reconciliation decision is in that one file. The 6-year HIPAA retention expectation is met by automated daily encrypted backups (SP17) and a tamper-evident hash-chained audit log (SP11).
 The whole stack is a single Python process (FastAPI + uvicorn on port 8000) plus a single Node process in dev (Vite on port 5173). No message broker, no separate worker, no database server. The v1 deployment model tolerates this because the operator is one person, the host is one machine, and the failure mode is "open the Activity log and check what broke."

 **One process, one file, three side-channels.** The Keychain (secrets) and SFTP (outbound to the payer) are side-channels; the database is the central state.
 The `cyclone-pipeline/` sibling project (not in this repo) is a separate Python CLI that drives the full 7-phase round-trip: preflight → browser upload → parse verification → SFTP submit → TA1 wait → 999 wait → scan + report. It is not part of the in-process architecture; it sits alongside the backend and uses its API endpoints.

 ### 3.3 External / operational
 - **macOS Keychain** — secret store for SQLCipher key, SFTP password, backup passphrase. No secrets on disk in plaintext (NFR-4).
 - **X12 005010 implementation guides** — the parsers follow the CMS / X12 published guides. The 837P parser is the most heavily tested; 835 is the second; 999/TA1/270/271/277CA are lighter.
 - **One trading partner** — Colorado Medicaid via the Gainwell SFTP endpoint. Other payers are configured via `cyclone/providers.py` `PayerConfig` rows (SP9).

 ## 4. Backend architecture
 ### 4.1 Package layout
 The `cyclone` package is a single namespace rooted at `backend/src/cyclone/`. 22 top-level modules + 4 subpackages. The store (SP21 in-flight split) is the largest; everything else is small and focused.

 | `auth.*` | HTTP-layer login (bcrypt + HttpOnly session cookie). Submodules: `deps` (the `matrix_gate` FastAPI dependency, `AUTH_DISABLED` flag), `routes` (`/api/auth/login`, `/api/auth/logout`, `/api/auth/me`), `users`, `sessions`, `permissions` (role matrix), `bootstrap` (env-var first-admin), `cli` (`cyclone admin create-user` / `rotate-password`) |

 | `secrets` | Keychain get/set/delete via `keyring` |
 | `security` | Security headers, deep `HealthSnapshot` (SP19) |
 | `store` | `CycloneStore` facade: `add` / `get` / `list` / `manual_match` / `iter_*` / `recent_activity` |
 ### 4.3 The `CycloneStore` facade
 The store is the single read/write surface for the database. Every endpoint that mutates state goes through `cyclone.store` (eventually the `cyclone.store.*` subpackage after SP21 lands). The facade pattern preserves public API:
 - `store.add(record)` — add a parsed batch
 - `store.get(batch_id)`, `get_batch(batch_id)`, `list(limit)`, `all()`
 - `store.manual_match(claim_id, remit_id)` — raises `AlreadyMatchedError` (→ 409)
 - `store.manual_unmatch(claim_id)` — raises `NotMatchedError` (→ 409)
 - `store.iter_claims(...)`, `iter_remittances(...)`
 - `store.distinct_providers()`, `recent_activity(limit)`
 - `store.list_unmatched(kind="both")`
 - `store.export_*()` — CSV/JSON dumpers
 All persistence flows through SQLAlchemy sessions via `db.SessionLocal()()`. The engine is single-connection-per-request via FastAPI dependency injection. SP21 splits `store.py` (2,423 LOC) into a `cyclone/store/` subpackage with one module per domain (batches, inbox, claim_detail, acks, backups, providers, etc.) and a thin facade that delegates every method to its domain module. After SP21, the public API of `cyclone.store` is unchanged; the only thing that changes is the file layout.
 ### 4.4 The parser pipeline
 All inbound files follow the same 5-stage pipeline:
 ```
 X12 .txt on disk
  ↓
  [1] tokenize    (parsers/segments.py: split on ~, then ^, then *:)
  ↓
  [2] segmentize  (build Segment records with elements + repeats)
  ↓
  [3] model       (parsers/models_*.py: Pydantic models per transaction type)
  ↓
  [4] validate    (parsers/validator.py: R-codes; raise ParseError on fatal)
  ↓
  [5] write       (store.add(record); record → DB rows)
 ```
 The 837P validator has the most rules (R020, R021, R034, R035, R200, R210 — see [837P parser spec](superpowers/specs/2026-06-19-cyclone-837p-parser-design.md) §2.4 for the registry). The 835 validator is simpler (no R-codes, just a model completeness check + a status_code allowlist). 999/TA1/270/271/277CA have no validators — they trust the upstream.
 The writer is responsible for: (a) creating the `batches` row, (b) creating N `claims` / `remittances` / `cas_adjustments` rows, (c) emitting an `activity_events` row, (d) for 837P, the synthetic claim-status from the 999 envelope, (e) for 835, triggering `reconcile.apply_payment` to auto-match. If any step raises, the entire batch is rolled back (single SQLAlchemy transaction).
 ### 4.5 The reconciliation engine
 `cyclone.reconcile` is a pure-functions module. The store calls into it for every 835 ingest:
 - `apply_payment(claim, remit, strategy) -> ApplyIntent` — happy path; returns the new `Match` row + state transition
 - `apply_reversal(...)` — handles a reversal 835 (the original payment + the reversal both stay in the DB; the `is_reversal` flag on the `Match` row disambiguates)
 - `recompute_line_totals(claim)` — for SP7's per-line audit, when an 835 carries CAS adjustments
 The engine is pure (no DB access). The store orchestrates the SQL writes after a successful `apply_*` returns. The 4-field scoring (40/25/20/15 for charge amount / NPI / patient ID / service date) lives in `cyclone.scoring` and is invoked by `inbox_lanes.compute_lanes` for the `candidates` and `unmatched` lanes.
 ### 4.6 The audit chain
 `cyclone.audit_log` is a separate, append-only log table (`audit_log` — distinct from `activity_events` which is the un-chained `/activity` feed). Every event type the system can emit has a key in the chain:
 - `claim.submitted`, `claim.rejected`, `claim.matched`, `claim.unmatched`
 - `claim.payer_rejected`, `claim.payer_rejected_acknowledged`
 - `clearhouse.submitted`
 - `key.rotated` (SP15), `backup.created`, `backup.restored`, `backup.verified` (SP17)
 - `api.request_rejected` (SP19)
 Each row carries the SHA-256 of `(prev_hash || kind || actor || payload_json || ts)`. The first row has `prev_hash = 0x00 * 32`. `audit_log.verify_chain()` walks the table top-to-bottom, recomputing each hash, and raises `AuditChainError` on the first mismatch with the row id and the expected vs. actual hash. SP19's deep health probe calls `verify_chain()` on every `/api/health` request so a broken chain surfaces in the operator's status badge within one tick.

 ## 5. Frontend architecture
 ### 5.1 Tech stack
 See §3.2. The frontend is a Vite SPA with TypeScript strict mode, Tailwind utility classes, and Radix primitives. There is no SSR, no Next.js, no router data-loading — every page is a function component that calls `useQuery` and renders.
 ### 5.2 Route map
 | Path | Page | Purpose |
 |---|---|---|
 | `/` | `Dashboard` | KPI tiles + ticker tape + recent activity |
 | `/claims` | `Claims` | Paginated claim list, filters, drill to claim drawer |
 | `/remittances` | `Remittances` | Paginated remit list, drill to remit drawer |
 | `/providers` | `Providers` | Provider rollup (NPIs, charge totals) |
 | `/activity` | `ActivityLog` | Append-only `activity_events` feed (NDJSON) |
 | `/upload` | `Upload` | Drag-drop or click to upload an 837P / 835 / 999 / 277CA |
 | `/reconciliation` | `ReconciliationPage` | Cross-claim reconciliation view (4-field score) |
 | `/inbox` | `Inbox` | 5-lane inbox (SP14) with BulkBar |
 | `/acks` | `Acks` | 999/TA1/270/271/277CA acknowledgment list |
 | `/batches` | `Batches` | Batch list with totals + validation summary |
 | `/batch-diff` | `BatchDiff` | Pairwise 837 batch diff |
 | `*` | `NotFound` | 404 |
 ### 5.3 State management
 Two layers:
 - **Server state** — `@tanstack/react-query`. Every page uses one or more `useQuery` calls. The query key shape is `["domain", id?, filters?]`. Mutations use `useMutation` and invalidate the relevant keys. There is no global refetch strategy; each page controls its own stale time.
 - **Client state** — `zustand`. Two stores:
  - `tail-store.ts` — the live-tail connection state (reconnecting, last event id, subscriber counts). Powers the bottom-right TailStatusPill.
  - `DrillStackProvider` (in `src/components/drill/`) — the SP22 universal-drilldown stack. A LIFO of drill contexts (claim → claim line → match → CAS adjustment) so the back button works across drawers.
 There is no Redux, no Context for global state, no MobX. The combination of react-query for server state + zustand for client state is intentional — see [universal-drilldown spec](superpowers/specs/2026-06-21-cyclone-universal-drilldown-design.md) for the rationale.
 ### 5.4 Live tail (NDJSON pubsub)
 The Activity feed and the TailStatusPill share a single connection: `GET /api/tail?since=<last_event_id>`. The server returns `Content-Type: application/x-ndjson` and streams one JSON object per line. Each line is one of:
 - `{kind: "heartbeat", ts: "..."}` — every 5s when no events
 - `{kind: "event", id: <int>, event_type: "...", payload: {...}}` — when something happens
 - `{kind: "error", message: "..."}` — server-initiated close (rare)
 The client uses `fetch` + `ReadableStream` to consume the body and dispatches each line to the relevant `useQuery` cache via `queryClient.setQueryData`. The connection auto-reconnects on `error` with exponential backoff. See [live-tail spec](superpowers/specs/2026-06-20-cyclone-live-tail-design.md) for the wire format and reconnection policy.
 ---
 ## 6. Data model
 ### 6.1 Migrations 0001–0014
 The schema evolves in ordered SQL files under `backend/src/cyclone/migrations/`. Each file starts with `-- version: N` and is applied in order by `db_migrate.py`. There is no migration framework — `db_migrate.py` is a 30-line file that checks the `schema_version` row and applies everything newer. The first 12 ship on `main`; 13 + 14 are the auth migrations that landed in `main` on 2026-06-23.
 | # | File | What it adds |
 |---|---|---|
 | 1 | `0001_initial.sql` | `batches`, `claims`, `remittances`, `cas_adjustments`, `matches`, `activity_events` (6 tables) |
 | 2 | `0002_acks.sql` | `acks` table (999/271) |
 | 3 | `0003_drop_claims_remits_unique_constraints.sql` | Spec-bug fix: drop the UNIQUE constraints that prevented reversal flows |
 | 4 | `0004_rejections_and_state_history.sql` | `rejections` table + `claim_state_history` |
 | 5 | `0005_create_ta1_acks.sql` | `ta1_acks` table |
 | 6 | `0006_line_reconciliation.sql` | `line_reconciliations` (SP7) |
 | 7 | `0007_providers_payers_clearhouse.sql` | `providers`, `payers`, `clearhouses` (SP9) |
 | 8 | `0008_payer_rejected_columns.sql` | `claim.payer_rejected_*` columns (SP10) |
 | 9 | `0009_audit_log.sql` | `audit_log` hash-chained table (SP11) |
 | 10 | `0010_payer_rejected_acknowledged.sql` | `claim.payer_rejected_acknowledged_*` columns (SP14 hand-off) |
 | 11 | `0011_processed_inbound_files.sql` | `processed_inbound_files` idempotency table (SP16) |
 | 12 | `0012_backups.sql` | `db_backups` table (SP17) |
 | 13 | `0013_auth_users_and_sessions.sql` | `users` + `sessions` tables, `users.password_hash` (bcrypt) — landed 2026-06-23 |
 | 14 | `0014_audit_log_user_id.sql` | `audit_log.user_id` FK to `users.id` (forward reference to 0013) — landed 2026-06-23 |
 The SP22 parse-then-decide migrations (drop claims UNIQUE constraint + relax PK to `(batch_id, id)`) are renumbered to 0015 + 0016 on the `claims-unique-fix` worktree so the auth migrations stay at the front of the chain; they'll keep those numbers when SP22 lands.
 ### 6.2 ERD (high level)
 ```

 providers (1) ─< (N) claims
 payers (1)    ─< (N) claims
 clearhouses (1) ─< (N) payers
 ```
 The `batches` row is the parent of every parsed X12 file. A batch is the unit of atomicity for parsing: either every claim/remit/ack in the file lands, or the file rolls back. The `claims.state` column drives the lifecycle (§6.3); the `matches` table is the join that says "this 835 paid this 837" (with a `strategy` field for audit: auto vs. manual).
 ### 6.3 Claim lifecycle (7 states)
 The `claims.state` column is the canonical state of a claim in the operator's workflow:
 ```
   submitted ──> accepted ──> paid
        │           │           │
        │           │           └─> reversed
        │           │
        │           └─> denied ──> appealed ──> paid
        │
        └─> rejected (envelope 999)
                │
                └─> payer_rejected (277CA A4/A6/A7)
 ```
 - `submitted` — 837P ingested, awaiting 999 ACK
 - `accepted` — 999 ACK came back clean; sitting in the trading partner's queue
 - `paid` — 835 matched, payment posted
 - `reversed` — 835 reversal applied (the original payment + the reversal are both preserved; the `state` reflects the most recent)
 - `denied` — 835 came back with a denial status code (CAS group CO)
 - `appealed` — operator flagged for appeal workflow
 - `rejected` — envelope-level 999 rejection (syntactic / structural)
 - `payer_rejected` — semantic 277CA rejection (A4/A6/A7 — claim accepted by envelope but rejected at the line level). SP10 introduced this state and the `claim.payer_rejected_*` columns.
 State transitions are explicit functions in `cyclone.store` (e.g. `mark_accepted`, `mark_paid`, `mark_rejected`). Each transition emits an `activity_events` row and, for the security-relevant ones, an `audit_log` row.
 ### 6.4 Audit chain integrity
 The `audit_log` table is a separate chain from `activity_events`:
 - `activity_events` — un-chained, powers the `/activity` feed. The activity feed can be repopulated from the underlying state if rows are missing; integrity is informational.
 - `audit_log` — SHA-256 hash-chained, powers compliance / forensics. A row cannot be deleted without breaking the chain. `audit_log.verify_chain()` is the integrity check; the SP19 deep health probe runs it on every `/api/health` call.
 The two are intentionally separate because they have different retention and integrity requirements. The convention-vs-trigger tradeoff is documented in the [SP11 spec](superpowers/specs/2026-06-23-cyclone-sp11-hash-chained-audit-design.md) §7.

 ## 7. Data flow
 ### 7.1 File ingest (manual upload)

                       CycloneStore.add(record)  (single SQLAlchemy transaction)

                          ├─> emit activity_events row
                          ├─> for 835: trigger reconcile.apply_payment
                          ├─> for 999/TA1/277CA: mark the source claim
                          └─> commit

                       live-tail subscribers (Activity feed, TailStatusPill)
 ```
 The HTTP response is the new `batch_id` + a counts summary (e.g. `{"batch_id": "...", "claims": 12, "remittances": 0, "validation_issues": 0}`). The 999 is the only case where the response carries an ack payload — the operator can read the parsed 999 directly without a second request.

 ```
 The idempotency table is the linchpin: a crash between "read file" and "INSERT processed" results in the same file being processed again on the next tick. The 5-step ordering (SELECT → INSERT side-effects → INSERT idempotency; IntegrityError as the correctness backstop) is detailed in the [SP16 spec](superpowers/specs/2026-06-23-cyclone-sp16-mft-polling-design.md) §3.4.
 ### 7.3 File ingest (manual upload, replayed by pipeline)
 `cyclone-pipeline/` (sibling project) does the same as the operator dragging-and-dropping — it `POST`s to `/api/upload` with the file. There's no separate "pipeline" ingestion path. The pipeline agent is a thin wrapper that adds preflight + SFTP submit + wait-for-999 around the Cyclone API.
 ### 7.4 Auto-match on 835 ingest
 When an 835 lands, the writer calls `reconcile.apply_payment(claim, remit, strategy)` for each `(claim, remit)` pair in the file. The strategy is one of:
 - `auto:pcn_npi_charge` — patient_control_number + provider_npi + charge_amount match (the strongest)
 - `auto:pcn_charge` — patient_control_number + charge_amount (the most common in practice)
 - `manual` — the operator uses `/reconciliation` to pair by hand; the strategy is recorded for audit
 Each auto-match creates a `matches` row + transitions the claim state + emits an `activity_events` row + emits an `audit_log` row. The match rate is visible in the Dashboard KPI tile.
 ### 7.5 Outbound 837P (resubmit)
 Two paths:
 - **Single claim** — `GET /api/claims/{id}/serialize-837` (SP8). The serializer round-trips the claim through `serialize_837.py`, validates with the R-code registry, and returns the X12 text. The Claim drawer's "Download 837" button calls this and triggers a browser download.
 - **Bundle ZIP** — `POST /api/claims/resubmit?download=zip` (SP8). The serializer rebuilds N 837P files (one per claim in the request), zips them with a manifest, and returns the ZIP. The Inbox BulkBar's "Resubmit selected" calls this.
 Both paths are read-only against the DB (they don't mutate the claim state). The operator is expected to download the regenerated file, then submit it manually via SFTP (or via `cyclone-pipeline run`).
 ### 7.6 Acknowledgement ingestion (999, TA1, 277CA)
 These are the three "ack" transaction types the operator's trading partner sends back after a submission:
 - **999** — functional ack (envelope-level). Triggers `claim.state = accepted | rejected`.
 - **TA1** — interchange ack. Triggers an activity_events row; no state change.
 - **277CA** — claim status (line-level). Triggers `claim.payer_rejected` if any line is A4/A6/A7. The `claim.payer_rejected_*` columns carry the status code + the 277CA's batch id for the audit trail.
 All three are ingested via the same `/api/upload` path; the parser auto-detects the transaction type from the ISA segment. The SP10 spec describes the monotonic rule: a later 277CA cannot clear a previous rejection. This is the regulatory guarantee the SP11 audit chain relies on.

 ## 8. API surface
 ### 8.1 REST endpoints (by domain)
 The full list is in [REQUIREMENTS.md §6.3 traceability matrix](REQUIREMENTS.md). The structure is:
 ```

 /api/batches/{id}/diff?against={other_id}    (batch_diff)
 /api/batches/{id}/serialize-837              (SP8 — round-trip)
 /api/claims                                  (list, paginated, filterable)
 /api/claims/{id}                             (detail, with remits + matches + line_recons)

 /api/providers/{npi}                         (single provider, all claims)
 /api/activity?since=<id>                     (un-chained feed, paginated)
 /api/inbox                                   (SP14 5-lane view, filterable)

 /api/acks/{id}                               (detail)
 /api/ta1-acks                                (TA1 list)

 /api/admin/scheduler/stop                    (SP16)
 ```
 ### 8.2 Live-tail NDJSON format
 `GET /api/tail?since=<last_event_id>` returns `Content-Type: application/x-ndjson` and streams:
 ```
 {"kind":"event","id":1234,"event_type":"claim.submitted","payload":{"claim_id":"...","batch_id":"...","ts":"2026-06-23T..."}}
 {"kind":"event","id":1235,"event_type":"claim.matched","payload":{"claim_id":"...","remit_id":"...","strategy":"auto:pcn_npi_charge"}}
 {"kind":"heartbeat","ts":"2026-06-23T..."}
 {"kind":"event","id":1236,"event_type":"claim.payer_rejected","payload":{"claim_id":"...","status_code":"A7","source_277ca_id":"..."}}
 ```
 Heartbeats every 5s when no events. The client reconnects on `error` with exponential backoff capped at 30s. See [live-tail spec](superpowers/specs/2026-06-20-cyclone-live-tail-design.md) for the full wire format.
 ---
 ## 9. Cross-cutting concerns
 ### 9.1 Logging (SP18)
 `cyclone.logging_config` configures a single JSON formatter that:
 - Emits one JSON object per line to stdout (12-factor)
 - Includes `ts`, `level`, `logger`, `msg`, `module`, `line`, `process`, `thread`
 - Scrubs PHI/PII fields by key name (`npi`, `member_id`, `patient_name`, `ssn_last4`, `charge_amount`, `paid_amount`, `tax_id`) — replaced with `***`
 - Redacts secrets by string match (anything matching `password=...&` or `Bearer ...`)
 The PII scrubber is a best-effort defense-in-depth, not a security boundary. Real PHI protection comes from the SQLCipher layer (SP12) and the Keychain (no secrets in env). The scrubber exists so an operator tailing logs to debug doesn't accidentally paste a log line into a chat.
 ### 9.2 Audit chain (SP11)
 See §4.6. The chain is checked on every `/api/health` request and exposes `status="degraded"` if broken. The operator sees the status in the TailStatusPill and the Dashboard KPI tile.
 ### 9.3 PHI/PII handling
 - **Storage** — SQLCipher at rest (opt-in, SP12). Daily encrypted backups (SP17). Tamper-evident audit chain (SP11). 6-year retention via automated backup rotation.
 - **In transit (SFTP)** — TLS to the trading partner; no plaintext EDI over the wire.
 - **In the UI** — no PHI is shown on the Dashboard or Inbox (only counts + KPIs). The Claim drawer and Remit drawer show full PHI; these pages are not in the route map's preview and require an explicit navigation click.
 - **In logs** — scrubbed by key name (see §9.1).
 - **In analytics** — no analytics. No third-party tracking. No telemetry. The frontend makes no requests outside `127.0.0.1:8000`.
 ### 9.4 Error model
 Every API error is a JSON object with `{"error": "<code>", "message": "<human>", "detail": <optional>}`. The mapping is in `api_helpers.py`:
 | Error class | HTTP status | `error` code |
 |---|---|---|
 | `AlreadyMatchedError` | 409 | `already_matched` |
 | `NotMatchedError` | 409 | `not_matched` |
 | `InvalidStateError` | 409 | `invalid_state` |
 | `ParseError` | 422 | `parse_error` |
 | `ValidationError` (R-codes) | 422 | `validation_failed` (issues in `detail`) |
 | `FileNotFoundError` | 404 | `not_found` |
 | `ValueError` | 400 | `bad_request` |
 | `PermissionError` | 403 | `forbidden` (raised by `matrix_gate` when the role is below the endpoint's required role) |
 | (anything else) | 500 | `internal` (with a request id for log correlation) |
 The 409-vs-422-vs-400 split is intentional: 409 for state-machine violations (the operator's input is well-formed but conflicts with current state), 422 for parse / validation, 400 for bad input shape.
 ---
 ## 10. Operational concerns
 ### 10.1 Startup order
 `python -m cyclone serve` → `cyclone.api.lifespan` runs:
 1. `db.init_db()` — apply pending migrations (0001-0012, plus 0013/0014 on the `claims-unique-fix` worktree)
 2. Seed `cyclone.providers` with the SP9 defaults if the table is empty (PayerConfig for Colorado Medicaid + Gainwell)
 3. Configure `BackupService` (SP17) — open backup dir, read passphrase from Keychain
 4. Configure `Scheduler` (SP16) — wire MFT polling for each clearhouse
 5. If `CYCLONE_SCHEDULER_AUTOSTART=true` (default), start both schedulers
 6. Mount the FastAPI app and start uvicorn
 The ordering is load-bearing: the store facade cannot be used until `init_db` finishes, and the schedulers cannot query the DB until the seed step populates the clearhouse rows.
 ### 10.2 MFT scheduler (SP16)
 `cyclone.scheduler.Scheduler` runs a per-clearhouse tick on a configurable interval (default 30s, per `CYCLONE_SCHEDULER_INTERVAL` env var). The tick is described in §7.2. The scheduler is opt-in via `CYCLONE_SCHEDULER_AUTOSTART`; the operator can start/stop it from the admin endpoints or via `POST /api/admin/scheduler/tick` for a manual tick.
 The 4-step idempotency sequence (SELECT → INSERT side-effects → INSERT idempotency; IntegrityError as the correctness backstop) is the linchpin. The scheduler's `_already_processed` + `_record` pair wraps the INSERT to handle the case where two ticks race (an extremely rare event given the 30s interval, but possible during operator-driven manual ticks).
 ### 10.3 Backup scheduler (SP17)
 `cyclone.backup_scheduler.BackupScheduler` wraps `BackupService` and ticks on its own interval (default 24h, per `CYCLONE_BACKUP_INTERVAL` env var). On each tick: create a backup, prune anything older than `retention_days` (default 30). Auto-start opt-in via `CYCLONE_BACKUP_AUTOSTART`.
 The encryption layer is independent of SQLCipher: AES-256-GCM with a passphrase-derived key (PBKDF2-HMAC-SHA256, 200k iterations). The passphrase lives in the macOS Keychain. If the passphrase is missing, the backup layer falls back to deriving a key from the SQLCipher key (less ideal but never silently broken — the operator's `/api/health` reports `status="degraded"` with a `backup.passphrase_missing` flag).
 ### 10.4 Health probe (SP19)
 `GET /api/health` is a deep snapshot:
 - **db** — open a session, `SELECT 1`
 - **scheduler** — last tick ts, is alive
 - **pubsub** — current subscriber counts per event kind
 - **batch** — most recent batch id + ts
 - **audit_log** — `verify_chain()` result (deep check on every call; 1ms on a healthy chain, fails loudly on a broken one)
 - **backup** — last backup ts, last verify result, passphrase presence
 - **encryption** — `is_encryption_enabled()` boolean
 Returns `status="ok"` only when every subsystem is healthy. `status="degraded"` if any subsystem is unhappy but the API itself is responsive. The status is shown in the TailStatusPill (bottom-right) and the Dashboard KPI tile.
 ### 10.5 Shutdown
 `SIGTERM` (or Ctrl-C) → uvicorn drains in-flight requests → cancels the MFT scheduler (in-flight tick completes via `asyncio.to_thread`) → cancels the backup scheduler (in-flight tick completes) → closes the SQLAlchemy engine → exits 0. There is no checkpoint; the in-flight tick is allowed to complete naturally because the idempotency table makes a partial-tick restart safe.
 ---
 ## 11. Deployment
 ### 11.1 Local dev (default)
 The default deployment. Two terminals:
 ```bash
 # Terminal 1 — backend on 127.0.0.1:8000
 cd backend
 .venv/bin/python -m cyclone serve
 # Terminal 2 — frontend on localhost:5173
 cd ..
 npm run dev
 ```
 The frontend reads its backend URL from `VITE_API_BASE_URL` (default empty). Create `.env.local` at the repo root with `VITE_API_BASE_URL=http://127.0.0.1:8000`. Without it, the UI falls back to its in-memory sample store via the `data` adapter (parses are disabled).
 ### 11.2 Optional Docker (SP23 — product fork)
 A Ubuntu + Docker + auth + RBAC + LAN-bind spec exists at [`docs/superpowers/specs/2026-06-22-cyclone-ubuntu-docker-deployment-design.md`](superpowers/specs/2026-06-22-cyclone-ubuntu-docker-deployment-design.md). This is a **product fork** awaiting user decision (per [REQUIREMENTS.md §6.2](REQUIREMENTS.md)). The v1 single-host single-operator posture assumes local-only; SP23 changes the threat model to "remote operator on LAN."
 ### 11.3 Single-host "production"
 For a single operator on a single machine, the dev deployment IS the production deployment. There is no separate build / deploy pipeline; the v1 distribution model is `git clone && pip install -e '.[dev]' && npm install && python -m cyclone serve`. A release-time gate (not yet implemented — backlog item) would run `pytest` (backend) and `npm test` (frontend) and fail if any test is red.
 ---
 ## 12. Out of scope (v1)
 The following are explicitly NOT built in v1, by design:
 - **Multi-user / multi-host** — login is required (single-user model today; SP23 adds RBAC). LAN-bind, Docker, reverse proxy still out of scope. (SP23 covers the LAN-bind / Docker / RBAC product fork.)
 - **Other trading partners** — only Colorado Medicaid via Gainwell is configured. The `PayerConfig` mechanism (SP9) supports adding more; the spec/plan/CLI work for that is on the backlog.
 - **837I / 837D / 834 / 820 / 275 / 278 / 276-277** — only 837P and 835 are first-class. Other transaction types are listed in [REQUIREMENTS.md §6.2](REQUIREMENTS.md) as backlog items.
 - **NPPES real-time lookup** — only local NPI checksum validation (SP20). The operator who wants real registry lookup has to wire it in later.
 - **EHR / PM integration** — no webhook in/out, no callable `POST /api/parse-837` (the pipeline agent uses `/api/upload` for now).
 - **COB / secondary claims** — no automatic coordination-of-benefits generator. The operator generates a secondary 837P by hand from the CAS adjustments.
 - **Real-time eligibility** — no SFTP pickup + SOAP + 271 round-trip. The 270/271 parsers exist; the live cycle doesn't.
 Each of these is a separate SP. The "v1 done" bar is the 22 shipped SPs (SP1–SP22) on `main` plus the [REQUIREMENTS.md §8 DoD](REQUIREMENTS.md).

 # Cyclone — Requirements, Architecture, Tasks, and Test Strategy
 **Date:** 2026-06-23
 **Status:** Round 2 (post-review corrections — ready for verification)
 **Audience:** New engineer or AI agent who needs to understand Cyclone's contract, the work that's already shipped, the work that's not, and what "done" means before they write a single line of code.
 **Scope:** Local-only, single-operator, single-host EDI claims-management suite for one billing office, currently trading with Colorado Medicaid (CO XIX).
 **Sister docs:** [`README.md`](../README.md) is the operator-facing entry point; [`docs/ARCHITECTURE.md`](ARCHITECTURE.md) is the top-level technical design (process topology, package layout, data flow, lifecycle); [`docs/superpowers/specs/`](superpowers/specs/) holds per-SP design specs; [`docs/superpowers/plans/`](superpowers/plans/) holds per-SP implementation plans; [`docs/reviews/2026-06-20-cyclone-completeness-review.md`](reviews/2026-06-20-cyclone-completeness-review.md) is the industry-scope gap analysis; [`docs/reference/`](reference/) holds condensed X12 / payer notes.
 ---
 ## 0. How to read this document
 | If you want to know… | Go to |
 |---|---|
 | What Cyclone is and is not | §1, §2 |
 | What it must do (functional) | §3 |
 | What it must *not* fail at (non-functional) | §4 |
 | How the system is built | §5 |
 | Which sub-project (SP) owns which requirement | §3 + §6 traceability matrix |
 | What "shipped" means | §7 |
 | What "done" means for the project as a whole | §8 |
 | How we test | §9 |
 | What we're assuming to be true | §10 |
 | What's still missing or risky | §11 |
 Every requirement (§3, §4) has an ID; every ID is traceable to a sub-project (§6) which in turn points at a design spec and an implementation plan. The matrix at the end of §6 is the single index that ties everything together.
 **Round history.** Round 1 (2026-06-23) produced this draft. Two independent reviewers (Reviewer A — components/data-model/deps/DoD; Reviewer B — traceability/consistency audit) read it against the actual codebase and surfaced 12 factual errors and 6 structural improvements. Round 2 (this version) applies every factual correction. Round 3 (pending) will re-verify reviewer agreement on the corrected doc.
 ---
 ## 1. The contract — what Cyclone is
 A self-hosted EDI claims-management suite for a single billing office. Parses 837P professional claims and 835 ERA remittances (X12 005010X222A1 and 005010X221A1), with a local-only FastAPI backend and a React UI for browsing, filtering, and inspecting the parsed data.
 - **Local-only on purpose:** binds `127.0.0.1`, requires login (auth boundary is HTTP; bcrypt + HttpOnly session cookie), no internet exposure, single operator, single machine, one trading partner (Colorado Medicaid, currently).
 - **Single-process:** the backend is one Python process; the frontend is one Vite-served React app; there is no message broker, no separate worker, no queue.
 - **Single source of truth:** SQLite at `~/.local/share/cyclone/cyclone.db` (overridable via `CYCLONE_DB_URL`); optionally encrypted at rest via SQLCipher (SP12).
 - **Threat model:** a process on the same host, plus a deliberate HTTP-layer login (no remote unauthenticated read or write). File-system threats (stolen/imaged drive) are still the primary concern; SQLCipher at rest + the macOS Keychain handle those. The SP23 product fork changes the threat model to "remote operator on LAN."
 The Cyclone codebase has honored this contract end-to-end across 22 shipped sub-projects. Every design spec re-asserts the local-only / single-operator / single-payer / no-auth posture and lists (often at length) what is intentionally out of scope.

 | Automated AES-256-GCM encrypted DB backups | SP17 |
 | Structured JSON logging + PII scrubber | SP18 |
 | Security hardening (body size limit, rate limit, security headers) | SP19 |
 | NPI Luhn checksum + Tax ID format validation | SP20 |
 | CycloneStore split (refactor; **in-flight on `refactor/store-split`**) | SP21 |

 ### 2.2 Out of scope (today, by design)
 | Item | Why |
 |---|---|
 | AS2 / AS4 (EDIINT, signed, encrypted, MDN-back) connectivity | Single-host local tool; the operator hands the 837 ZIP to the Gainwell MFT UI manually |
 | Real-time 270/271 round-trip over CAQH CORE Phase II/III SOAP envelopes | Out of single-host scope; builder + parser are X12-only |
 | 837I (institutional), 837D (dental), 834, 820, 275, 278, 276/277 | Single-payer scope; not currently demanded by the CO XIX workflow |
 | NPPES NPI registry lookup (offline validation only) | Single-host, no internet exposure |
 | ICD-10 / HCPCS / NDC vocabulary tables | Structural validation only; the operator has the source vocab |
 | COB / secondary-claim generator | Workflow scope |
 | HITRUST / SOC 2 / BAA template | Single-operator; threat model doesn't require them |
 | HA / DR / load balancing / multi-host replication | Single-host scope |
 | Prometheus / Grafana / alerting | `curl health \| mail` cron is sufficient |
 | 2FA / SSO / OAuth | Single-operator |
 | LUKS full-disk encryption | Operator / host concern |
 | Component / E2E browser tests (Playwright) | Local-only, manual smoke scripts are sufficient |
 ### 2.3 Deferred with rationale
 - **Public TLS / public domain / Caddy reverse proxy** — LAN-only bind is enough for the v1 single-Ubuntu-server posture; VPN handles outside access. (Re-evaluated if the Ubuntu Docker plan ships.)
 - **Off-box automated backup shipping** — host cron / rsync is documented in the operator runbook, not automated in code.
 - **Self-service password reset** — admin can reset via CLI; self-service is v2 (would only be relevant if auth ships).
 - **Per-file encryption of prodfiles / `sftp_staging`** — relies on volume-level filesystem permissions + the SQLCipher-encrypted DB + the host being physically secure.
 - **Watchtower / automatic updates** — manual `docker compose pull` keeps the operator in the loop on schema migrations.

 ## 3. Functional requirements
 Each requirement is `FR-NN`, traceable to one or more sub-projects. Verification is "shipped + tested" (see §6) or "planned" (see §6.2).
 | ID | Requirement | SP |
 |---|---|---|
 | FR-1 | Parse an uploaded 837P file into structured `Claim` records. | SP1 |
 | FR-2 | Parse an uploaded 835 file into structured `Remittance` records with per-CAS adjustment rows. | SP1 + SP3 |
 | FR-3 | Persist every successful parse to SQLite; survive backend restart. | SP2 |
 | FR-4 | Run a forward-compatible migration runner (`PRAGMA user_version`) so the schema can evolve without Alembic. | SP2 |
 | FR-5 | Auto-match each 835 `CLP` back to a prior 837 `Claim` within ±7 days via `(claim_id, service_date)`; apply lifecycle transitions; write `Match` and `ActivityEvent` rows. | SP2 |
 | FR-6 | Maintain a 7-state claim lifecycle (`submitted → received → paid|partial|denied → reconciled → reversed`) with `state_before_reversal` preserved on reversal. | SP2 |
 | FR-7 | Provide a `/reconciliation` page that lists unmatched claims and unmatched remittances and supports manual pair/unpair. | SP2 (tests live in `test_reconcile.py`, `test_reconcile_line_level.py`, `test_inbox_endpoints.py`, `test_api_gets.py`) |
 | FR-8 | Run structural 837P validation rules R021 (NPI checksum, warning-only), R034 (`REF*G1` on frequency 7/8), R035 (`BHT06` transaction-type allowlist), R200/R210. | SP3 + SP20 |
 | FR-9 | Generate a 999 ACK transaction set on 837 ingest when `?ack=true` is passed to `POST /api/parse-837`; persist it to the `acks` table. | SP3 |
 | FR-10 | Parse inbound 999 ACKs and surface them on a `/acks` page with regenerable raw text. | SP3 |
 | FR-11 | Parse + persist TA1 interchange ACKs (separate from 999 transaction-set ACKs). | SP3 |
 | FR-12 | Build a 270 from a JSON payload (`POST /api/eligibility/request`) and parse an inbound 271 (`POST /api/eligibility/parse-271`) into `coverage_benefits`. | SP3 |
 | FR-13 | Parse inbound 277CA files and stamp `payer_rejected` on claims whose STC category is A4/A6/A7 — monotonic (a looser later 277CA cannot downgrade). Also persist 277CA ACK rows to `two77ca_acks`. | SP10 |
 | FR-14 | Provide a `/inbox` page with five lanes ordered by urgency: Rejected (999 R/E), Payer-rejected (277CA A4/A6/A7), Candidates (CLP didn't auto-match), Unmatched (waiting), Done today (last 24h terminal transitions). | SP6 + SP10 + SP14 |
 | FR-15 | Score each Candidate on 4 weighted fields (patient control number 40, service date 25, charge amount 20, provider NPI 15); tier strong (≥75, Match enabled), weak (50–74, dimmed), hidden (<50). | SP6 |
 | FR-16 | Provide per-claim and per-remit detail drawers with full raw X12 segments, state-history timeline, validation panel, line-level reconciliation tab, and party grid. URL is synced (`?claim=…`, `?remit=…`). | SP4 + SP7 + SP21 |
 | FR-17 | Provide a side-by-side Batch Diff view (added / removed / changed claims). | SP4 (logic lives in `cyclone/batch_diff.py`) |
 | FR-18 | Provide a global Cmd-K search across claims, remittances, activity, and acks. | SP4 |
 | FR-19 | Provide per-page CSV export for claims, remittances, and inbox lanes. | SP4 |
 | FR-20 | Provide a live-tail NDJSON stream on `/api/{claims,remittances,activity}/stream` with snapshot-first, `snapshot_end`, heartbeat, and reconnect. | SP5 |
 | FR-21 | Surface a `TailStatusPill` with states `live / connecting / reconnecting / stalled / error / closed`, with backoff ladder `1s → 2s → 4s → 8s → 16s → 30s` capped. | SP5 |
 | FR-22 | Tie every 835 CAS adjustment back to the specific 837 SV1 service line it adjudicates; surface unmatched-line warnings. | SP7 (line-reconciliation rows in `line_reconciliations`) |
 | FR-23 | Serialize a single edited claim back to a valid X12 837P file with round-trip guarantee (113 prodfiles parse → serialize → parse to the same `claim_id`). | SP8 |
 | FR-24 | Export a ZIP bundle of selected rejected claims as a batch ready to hand to the MFT UI. | SP8 |
 | FR-25 | Load payer / payer_config / clearhouse config from `config/payers.yaml` (parsed via `pyyaml`) and 3 new DB tables (`providers`, `payers`, `payer_configs`); replace the in-code `PAYER_FACTORIES` dict. | SP9 |
 | FR-26 | Push a `cyclone clearhouse submit` to the Gainwell MFT inbound path via `paramiko` (`SftpClient` lives in `cyclone/clearhouse/__init__.py`). Credentials read from the macOS Keychain via the `keyring` library at call time. | SP13 |
 | FR-27 | Poll the Gainwell MFT inbound path every tick (configurable); route downloaded files to the right parser (999 / 835 / 277CA / TA1); idempotent via `processed_inbound_files`; crash-safe via per-file try/except. | SP16 |
 | FR-28 | Optionally encrypt the SQLite file via SQLCipher (AES-256); key fetched from the macOS Keychain via `keyring`. Falls back to plain SQLite if the Keychain entry is missing. | SP12 |
 | FR-29 | Rotate the SQLCipher key in place via `PRAGMA rekey`, serialized through a `threading.Lock` and SQLAlchemy `NullPool`; write `db.key_rotated` audit event with old + new key fingerprints and post-rotation `table_count`. | SP15 |
 | FR-30 | Produce AES-256-GCM encrypted DB backups (PBKDF2-HMAC-SHA256, 200k iters) via the existing `BackupService`; two-step restore (`initiate` → `confirm` with one-shot 64-char hex token); retention pruning with a 30-day default. Backups table is `db_backups`. | SP17 |
 | FR-31 | Emit all API / CLI / scheduler / backup logs as newline-delimited JSON with ISO-8601 ms timestamps; redact obvious PHI (NPIs, SSNs, DOBs, patient names) via a `PiiScrubber` filter on message + extras. | SP18 (uses stdlib `logging` + a JSON formatter, not structlog) |
 | FR-32 | Reject oversize request bodies (413), rate-limit requests (429), and add default security headers via pure-ASGI middlewares; emit a tamper-evident `api.request_rejected` audit event on 413/429. | SP19 |
 | FR-33 | Surface a rich `GET /api/health` response — DB connectivity, MFT scheduler state, backup scheduler state, live pubsub subscriber counts, last batch id + timestamp. | SP19 (`api_routers/health.py:28-40`) |
 | FR-34 | Validate NPI with the CMS-published Luhn over `80840 + body` (warning-only — placeholder NPIs in test fixtures shouldn't block ingest). Reject Tax ID (EIN) with reserved prefixes (`00`, `07`, `80`–`89`). | SP20 |
 | FR-35 | Split `CycloneStore` into per-concern modules (`store_persistence`, `store_reconcile`, `store_queries`, `store_mappers`) without changing the public store API. | SP21 (**in-flight** on `refactor/store-split` branch) |
 | FR-36 | De-duplicate 837 / 835 uploads via a parse-then-decide workflow (`find_existing_batch_for_claim` / `find_existing_batch_for_remit`); relax the claims/remits PK to `(batch_id, id)` via migration 0014 to support re-parses into different batches. | SP22 (migration 0014 in worktree; not yet on `main`) |
 | FR-37 | (Sibling project, not in this repo) Drive the full 7-phase round-trip — preflight → browser upload → parse verify → SFTP submit → TA1 wait → 999 wait → scan + report — with crash-safe resume, structured JSON logging, idempotency dedup, per-run folder. | SP22 (`cyclone-pipeline/`) |
 | FR-38 | Provide a `DrillStackProvider` + `DrillDrawerHeader` shell so every drillable cell across the app opens a consistent drawer or peek modal. | SP21 |
 ---
 ## 4. Non-functional requirements
 | ID | NFR | Source / SP |
 |---|---|---|
 | NFR-1 | **Local-only bind + auth.** Backend binds `127.0.0.1:8000` (overridable via `CYCLONE_PORT`); CORS allowlist is exact (`http://localhost:5173`); login required (bcrypt + HttpOnly session cookie; first admin bootstrapped from env vars `CYCLONE_ADMIN_USERNAME` + `CYCLONE_ADMIN_PASSWORD`); dev/test escape hatch via `CYCLONE_AUTH_DISABLED=1` (logs WARNING at boot). | SP1 + auth (2026-06-23 merge) + SP24 (doc reconciliation) |
 | NFR-2 | **Determinism.** Parser / serializer round-trip is guaranteed on 113 real prodfiles (`docs/prodfiles/claims/*.x12`); canonical fields, not byte-identity (called out in the SP8 spec). | SP8 |
 | NFR-3 | **Audit completeness.** Every reconciliation anomaly, every state transition, every 999/277CA reject writes an `ActivityEvent` (in `activity_events` table, un-chained; powers the `/activity` feed and inbox state transitions). | SP2 + SP10 |
 | NFR-4 | **Tamper-evidence.** A separate `audit_log` table (SP11) carries SHA-256 hash-chained rows for security-sensitive events (login attempts, rejections, key rotations, backup lifecycle, rejected requests). `GET /api/admin/audit-log/verify` detects any break. **The `activity_events` (NFR-3) and `audit_log` (NFR-4) tables are distinct** — different semantics, different audiences. New code that needs an audit row must decide which one to write to. | SP11 |
 | NFR-5 | **Encrypted at rest (optional).** SQLite is encrypted via SQLCipher AES-256 when the macOS Keychain entry exists and `sqlcipher3` is installed; plain SQLite otherwise. | SP12 |
 | NFR-6 | **Encrypted backups.** Backups are AES-256-GCM encrypted at rest (PBKDF2-HMAC-SHA256, 200k iters); passphrase lives in the macOS Keychain (`cyclone backup init-passphrase`). | SP17 |
 | NFR-7 | **Logging discipline.** API / CLI / scheduler / backup logs flow through a `JsonFormatter` (NDJSON, ISO-8601 ms) by default; `PiiScrubber` redacts obvious PHI; configurable via `CYCLONE_LOG_LEVEL` / `CYCLONE_LOG_FILE` / `CYCLONE_LOG_JSON` / `CYCLONE_LOG_NO_PII_SCRUB`. | SP18 |
 | NFR-8 | **Operational hygiene.** Request body size limit, rate limit, and default security headers are middleware-enforced (SP19). `EXEMPT_PATHS = ("/api/health", "/healthz", "/readyz")` is the documented bypass list (`cyclone/security.py:201`). | SP19 |
 | NFR-9 | **Thread-affinity.** SQLCipher operations are serialized through a `threading.Lock` + SQLAlchemy `NullPool` to keep SQLCipher thread-affine under FastAPI's per-request threadpool. | SP12 + SP15 |
 | NFR-10 | **Live-tail resilience.** Heartbeat every 15s default (`CYCLONE_TAIL_HEARTBEAT_S`); client flips to `stalled` after 30s of total silence (heartbeat included); reconnect backoff capped at 30s. | SP5 |
 | NFR-11 | **Payer config externalized.** Payer / payer_config / clearhouse config lives in `config/payers.yaml` + DB tables, not in code; a new payer is a YAML + DB row, not a code change. Note: `co_medicaid()` factory in `cyclone/parsers/payer.py:57-58` still exists as a fallback for tests and the default-payer selection (R-4 in §11). | SP9 |
 | NFR-12 | **Idempotency.** Inbound MFT files are de-duplicated via `processed_inbound_files`; 837/835 uploads are de-duplicated via the parse-then-decide workflow with `(batch_id, claim_id)` / `(batch_id, remit_id)` relaxed PKs. | SP16 + SP22 |
 | NFR-13 | **Crash-safety.** Incoming files are processed inside per-file try/except so a bad file doesn't stop the MFT loop; the pipeline agent has crash-safe resume keyed by run id. | SP16 + SP22 |
 | NFR-14 | **Single-process.** No message broker, no separate worker, no queue; everything runs in one Python process. | (project-wide constraint) |
 | NFR-15 | **Test density.** Backend tests: **964 collected** (`pytest --collect-only`, 2026-06-23); frontend test files: **73**; prodfiles are exercised (113 + 19 + 1369), not just minimal fixtures. | (project-wide) |
 | NFR-16 | **Documentation discipline.** Every shipped sub-project has a design spec + implementation plan + smoke test; a new engineer can read the project top-to-bottom. (SPs 9–16 ship without on-disk plan files — see §6.1 — but their `feat(spN)` commits are on `main` and carry their own commit-message plan.) | (project-wide) |
 | NFR-17 | **Fail-soft posture.** Reconciliation crashes don't lose the 835; the activity event records the failure. | SP2 |
 | NFR-18 | **Migration safety.** Migrations are forward-only via `PRAGMA user_version`; rollback procedures are documented per migration; the `user_version` runner is idempotent. **No checksum manifest exists today** (R-13 in §11). | SP2 + SP22 |

 ## 5. Architecture overview
 ### 5.1 Components
 **Backend (one Python process, FastAPI on uvicorn) — modules under `backend/src/cyclone/`:**
 | Module | Owns | Notes |
 |---|---|---|
 | `cyclone.api` | HTTP routes, content negotiation, CORS allowlist, lifespan | 3,145 LOC (largest single file; partly split into `api_routers/` for 4 sub-routes) |
 | `cyclone.api_helpers` | NDJSON / content-negotiation / live-tail helpers | |
 | `cyclone.api_routers` | `acks`, `admin`, `health` (`/api/health`), `ta1_acks` sub-routers | Mounted at `api.py:270-273`; only 4 routes split out — bulk of routes still in `api.py` |
 | `cyclone.store` | Public store facade; persistence, reconciliation, queries, mappers | 2,172 LOC; SP21 split is in-flight on `refactor/store-split` |
 | `cyclone.db` | SQLAlchemy engine, session factory, ORM models (18 tables) | |
 | `cyclone.db_migrate` | `PRAGMA user_version` migration runner | |
 | `cyclone.db_crypto` | Optional SQLCipher encryption at rest; key rotation | `rotate_key()` is destructive (rewrites every page) |
 | `cyclone.audit_log` | Hash-chained `audit_log` (SP11, SHA-256 chain) | Distinct from `cyclone.activity_events` written by other modules |
 | `cyclone.inbox_lanes` | The 5-lane inbox payload (Rejected / Payer-rejected / Candidates / Unmatched / Done today) | |
 | `cyclone.inbox_state` | 999 envelope reject → claim state transitions | |
 | `cyclone.inbox_state_277ca` | 277CA STC A4/A6/A7 → payer_rejected stamp (monotonic) | |
 | `cyclone.providers` | Multi-NPI provider lookups | |
 | `cyclone.payers` | Payer / payer_config lookups | Loads `config/payers.yaml` via `pyyaml` |
 | `cyclone.secrets` | macOS Keychain-backed secret fetcher (wraps `keyring`) | |
 | `cyclone.reconcile` | Pure-function 835→claim match + line-level match | No DB session inside; testable with fabricated ORM objects |
 | `cyclone.scoring` | 4-field weighted candidate scoring (40/25/20/15) | Weights hardcoded — see R-10 in §11 |
 | `cyclone.pubsub` | In-process EventBus (drop-oldest, per-kind fan-out) | In-process only; not thread-safe across asyncio event loops |
 | `cyclone.backup` | AES-256-GCM encrypted backups (orchestration + CLI) | 216 LOC |
 | `cyclone.backup_service` | Backup lifecycle (create / verify / restore) | 740 LOC |
 | `cyclone.backup_scheduler` | 24h backup autostart loop | 315 LOC |
 | `cyclone.scheduler` | asyncio MFT polling loop (SP16) | Uses `processed_inbound_files` for idempotency |
 | `cyclone.security` | Per-IP rate-limit, body-size limit, security headers (`SecurityHeadersMiddleware`, `BodySizeLimitMiddleware`, `RateLimitMiddleware`) | `EXEMPT_PATHS` list at `:201` |
 | `cyclone.logging_config` | JSON formatter, PII scrubber | |
 | `cyclone.npi` | NPI Luhn + EIN format validators | |
 | `cyclone.batch_diff` | Batch Diff engine (powers `GET /api/batch-diff`) | 12 public functions/classes |
 | `cyclone.clearhouse` (`__init__.py`) | `SftpClient` (SP9 stub + SP13 paramiko), `InboundFile`, `make_client()` factory | 318 LOC; the SFTP home |
 | `cyclone.edi` (`filenames.py`) | HCPF X12 File Naming Standards helpers | Used by SP13/SP16 outbound filename construction |
 | `cyclone.cli` | Click CLI | |
 | `cyclone.__main__` | `python -m cyclone serve` | |
 | `cyclone.parsers/` | X12 tokenizer, models, validator, writers, 277CA, 999, TA1, 270, 271, CAS, seg | 25 `.py` modules |
 **Stale artifact (do not import):** `backend/src/cyclone/workflow/` contains only a `__pycache__/` subdir with stale `.pyc` files (no `__init__.py`, no source). The actual sources live at the top level. Recommend deleting the directory.
 **Frontend (one Vite-served React app) — directories under `src/`:**
 | Directory | Owns |

 | `src/pages/` | Acks, ActivityLog, BatchDiff, Batches, Claims, Dashboard, Inbox, Providers, Reconciliation, Remittances, Upload (11 pages) |
 | `src/hooks/` | TanStack Query hooks, URL-state hooks, live-tail hooks, keyboard hooks, batch-export, search, drawer keyboard, count-up, provider detail, payer summary, parse, ack detail (35+ files) |
 | `src/lib/` | `api.ts`, `format.ts`, `utils.ts`, `csv.ts`, `download.ts`, `event-routing.ts`, `tail-stream.ts`, `inbox-api.ts` (all with paired `.test.ts`) |

 | `src/store/` | `index.ts` (zustand sample data), `tail-store.ts` (FIFO-capped live tail slices) |
 | `src/types/` | `index.ts` (flat barrel of shared TS types) |

 - `keyring>=25.0,<26` ← **macOS Keychain backend** used by `cyclone/secrets.py` (SP12/SP13/SP15); on Linux dispatches to Secret Service / kwallet
 - `cryptography>=49.0,<50`
 **Backend optional extras:**
 - `[sqlcipher]` → `sqlcipher3>=0.6,<1` (SP12; falls back to plain SQLite if missing)
 - `[sftp]` → `paramiko>=3.4,<6` (SP13)
 **Backend dev/test (`backend/pyproject.toml:27-33`):**
 - `pytest>=8.0`, `pytest-cov>=4.1`, `pytest-asyncio>=0.23,<1` (asyncio_mode = "auto"), `pytest-randomly>=4.1`, `httpx>=0.27,<1` ← **dev only, not runtime**
 - `ruff`, `mypy` — **not installed** (per completeness review §3.2.30 deferred)
 **Frontend runtime (verified against `package.json`):**
 - `react@^18.3.1`, `react-dom@^18.3.1`
 - `@tanstack/react-query@^5.101.0`
 - `lucide-react@^0.453.0`
 - `sonner@^1.5.0`
 - `zustand@^4.5.5`
 - `react-router-dom@^6.27.0` (note: package name is `react-router-dom`, not `react-router`)
 - `@radix-ui/react-dialog@^1.1.2`, `@radix-ui/react-label@^2.1.0`, `@radix-ui/react-select@^2.1.2`, `@radix-ui/react-slot@^1.1.0`, `@radix-ui/react-tabs@^1.1.15` ← powers `src/components/ui/` (shadcn primitives)
 - `class-variance-authority@^0.7.0`, `clsx@^2.1.1`, `tailwind-merge@^2.5.4`, `ansi-styles@^6.2.3` ← shadcn helper stack
 **Frontend dev/test:**
 - `vitest@^4.1.9` ← **unusually new version** (worth a sanity check — current stable is 1.x/2.x; verify it's intentional)
 - `@testing-library/react@^16.3.2`
 - `happy-dom@^20.10.6` ← **not jsdom** (vitest config line 13 explicitly says they don't need a DOM env: "Node 18+ exposes `Response` / `fetch` globals")
 - `typescript@^5.6.3`, `vite@^5.4.10`, `@vitejs/plugin-react@^4.3.3`
 - `@types/node`, `@types/react`, `@types/react-dom`, `autoprefixer`, `postcss`, `tailwindcss@^3.4.14`, `tailwindcss-animate`
 **External services:** None. (The MFT path is one-way outbound to Gainwell MFT, polled via SFTP — not a service Cyclone depends on, it's a sink it writes to.)
 **OS-level:** macOS Keychain (backed by `keyring`); SQLite / SQLCipher shared library; `ssh` host keys / known_hosts for SP13. SP23 would add `tini` + `curl` + `nginx` in container scenarios.

 ## 6. Sub-project inventory
 ### 6.1 Shipped SPs (in `main`)
 Each row's "Spec" / "Plan" point to the design spec and implementation plan on disk. SPs without a plan file on disk shipped via `feat(spN)` commits on `main` whose commit messages carry the implementation order; those commit logs substitute for a plan file. Closing the plan-file gap is on the round-3 backlog.

 ## 7. Acceptance criteria — per-SP (compressed)
 These are the existing per-SP acceptance checklists as captured in their design specs, condensed into one table. A new engineer can use this to know whether a given SP is "really done" without reading 22 specs end-to-end.
 | SP | Acceptance criterion | Verified by |
 |---|---|---|
 | SP1 | `pytest` passes; `/api/claims`, `/api/remittances`, `/api/providers`, `/api/activity`, `/api/batches`, `/api/batches/{id}` return JSON; CORS allowlist stays `http://localhost:5173`; bind stays `127.0.0.1` | `test_api_gets.py` + manual smoke |
 | SP2 | DB at `~/.local/share/cyclone/cyclone.db`; migrations apply on first run; 7-state Claim lifecycle; reconciliation runs on 835 ingest; `/reconciliation` page works | `test_db*.py`, `test_reconcile.py`, `test_reconcile_line_level.py`, `test_inbox_endpoints.py` |
 | SP3 | R034/R035/R200/R210 enforced; CAS reason codes surfaced; 999 in + out; TA1 in; 270/271 builder + parser | `test_validator*.py`, `test_acks.py`, `test_api_999.py`, `test_api_ta1.py`, `test_parse_270.py`, `test_parse_271.py` |
 | SP4 | Drawer opens with URL sync; Cmd-K search returns results across resources; batch diff renders added/removed/changed; CSV exports stream | `ClaimDrawer*.test.tsx`, `useSearch.test.ts`, `BatchDiff.test.tsx`, `ExportCsvButton.test.tsx` |
 | SP5 | `/api/{claims,remittances,activity}/stream` returns NDJSON with snapshot + `snapshot_end` + heartbeat; client flips to `stalled` after 30s silence; reconnect ladder capped at 30s | `test_api_stream_live.py`, `TailStatusPill.test.tsx` |
 | SP6 | `/inbox` shows 5 lanes (4 in SP6; 5th added in SP10); scoring tiers visible; bulk actions call the right endpoint | `test_inbox_lanes.py`, `BulkBar.test.tsx` |
 | SP7 | Line reconciliation tab in ClaimDrawer matches 837 SV1 ↔ 835 SVC strictly; unmatched-line warnings surfaced | `test_reconcile_line_level.py`, `test_api_line_reconciliation.py` |
 | SP8 | 113 prodfiles parse → serialize → parse back to the same `claim_id`; ZIP bundle export works | `test_prodfiles_smoke.py`, `test_api_batch_export_837.py` |
 | SP9 | `config/payers.yaml` loads (via `pyyaml`); new providers/payers/payer_configs tables populate; `clearhouse.submit` writes to `staging_dir` (stub) | `test_providers_seed.py`, `test_payer_config_loading.py` |
 | SP10 | 277CA parse + persist; `payer_rejected` stamp applied monotonically; lane 2 in `/inbox` renders | `test_parse_277ca.py`, `test_apply_277ca_rejections.py` |
 | SP11 | `audit_log` hash chain verifies via `GET /api/admin/audit-log/verify`; any break is detected | `test_audit_log.py`, `test_api_audit_log.py` |
 | SP12 | `db_crypto.is_encryption_enabled()` returns True when Keychain entry exists and `sqlcipher3` installed; otherwise falls back with WARNING | `test_db_crypto.py` |
 | SP13 | `SftpClient` actually pushes to `mft.gainwelltechnologies.com:…`; credentials read from Keychain via `keyring` at call time | `test_sftp_paramiko.py` (unit); integration via `cyclone-pipeline` |
 | SP14 | All 5 lanes render in `/inbox`; bulk acknowledge action drops payer-rejected claims without erasing the original rejection | `test_inbox_endpoints_sp7.py`, `test_lane_filter_acknowledged.py` |
 | SP15 | `POST /api/admin/db/rotate-key` runs `PRAGMA rekey`; emits `db.key_rotated` with old + new fingerprints; concurrent calls serialized | `test_api_rotate_key.py` |
 | SP16 | Scheduler ticks every interval; per-file try/except keeps the loop alive; `processed_inbound_files` de-duplicates | `test_scheduler.py`, `test_api_scheduler.py` |
 | SP17 | Backup scheduler ticks every 24h; encrypted `.bin` + `.meta.json` written; restore via 2-step token works; retention prunes at 30 days | `test_backup_*.py` |
 | SP18 | All logs emit as NDJSON by default; `PiiScrubber` redacts NPIs/SSNs/DOBs/names; `CYCLONE_LOG_JSON=0` falls back to `CycloneDevFormatter` | `test_logging_*.py` |
 | SP19 | 413 on oversize body, 429 on rate-limit, security headers present; `api.request_rejected` audit event on 413/429; `GET /api/health` returns rich payload | `test_security.py`, `test_api.py:33` |
 | SP20 | NPI Luhn catches 99% of typos; EIN rejects reserved prefixes; warning-only (placeholder NPIs in fixtures don't block ingest); CLI + API surface | `test_npi.py`, `test_api_validate_provider.py`, `test_cli_validate.py` |
 | SP21 | `CycloneStore` is split into `store_persistence / store_reconcile / store_queries / store_mappers`; public store API unchanged; `DrillStackProvider` + `DrillDrawerHeader` shell used by every drillable cell | `test_store.py` (split modules), `DrillStackProvider.test.tsx`, drawer-key tests |
 | SP22 | Re-parsing an 837 into a fresh batch does not 409 on `claim_id` collision; parse-then-decide workflow checks `find_existing_batch_for_claim`; pipeline agent runs 7 phases end-to-end | `test_api_parse_persists.py`, `test_prodfiles_smoke.py`, pipeline integration |

 ## 8. Definition of Done
 ### 8.1 Project-level DoD (the project as a whole is "done" when…)
 1. **All FRs in §3 are implemented and tested** — verifiable by walking the §6.3 traceability matrix and confirming each row links to either a passing test or an §2.2 out-of-scope entry.
 2. **All NFRs in §4 are met or have a documented exception** — NFR-1 through NFR-18 are each either met (with a citation) or carry an explicit exception in this section.
 3. **All shipped SPs in §6.1 have an Acceptance row marked "Met" and the corresponding tests pass.** Tests are run via `pytest` (backend) and `npm test` (frontend) per §9.4; **the project has no CI workflow today** (round-3 backlog item — see §6.2). A release-time gate should run the suites and fail if any test is red.
 4. **All backlog items in §6.2 are either scheduled, explicitly deferred with rationale, or removed** — testable as a checklist walk.
 5. **All assumptions in §10 are still valid** — re-checked at release time; an invalid assumption is either promoted to a backlog item or rolled into the next release.
 6. **All four reviewer questions (components / data model / dependencies / DoD) have independent agreement from at least two reviewers** — the meta-DoD: a doc with this scope is "done" when two reviewers can independently describe the system from it and agree.
 ### 8.2 Per-release DoD (the next release is "done" when…)
 1. The new SP's design spec has been **self-reviewed** (every claim cited with line/file, every assumption recorded).
 2. The implementation plan has **TDD-shaped tasks** with per-task acceptance criteria.
 3. Every task's tests are green in `pytest` (backend) and `npm test` (frontend) and `npm run build` (frontend typecheck + build).
 4. The new SP's Acceptance row in §6.1 is updated to "Met".
 5. New audit events (if any) are listed in the audit-log test fixtures (`backend/tests/test_audit_log.py`).
 6. Migration files (if any) follow the `NNNN_*.sql` ordering, append to this doc's §5.2 table, and (post-round-3) update the migration manifest (R-13).
 7. The README's project-layout section is updated if any module is added/renamed/removed.
 ### 8.3 Per-task DoD (the smallest unit of work is "done" when…)
 1. The code change is in a single commit (or a small, reviewable series).
 2. The matching test exists and passes.
 3. No existing test regresses.
 4. The commit message names the SP and the FR/NFR it advances (e.g., `feat(sp19): … (FR-32, NFR-8)`).
 5. If the task introduces a migration, it's added to `backend/src/cyclone/migrations/` with the next sequential `NNNN` and the new schema is reflected in §5.2.

 ## 9. Test strategy
 ### 9.1 Taxonomy
 | Layer | Tool | Where | What it covers |
 |---|---|---|---|
 | Backend unit | `pytest` | `backend/tests/` | Pure-function logic: `cyclone.reconcile.*`, `cyclone.scoring.*`, `cyclone.npi.*`, `cyclone.cas_codes`, `cyclone.audit_log.append_event`, `cyclone.edi.filenames` |
 | Backend integration | `pytest` (TestClient) | `backend/tests/test_api_*.py` | FastAPI route round-trips, content negotiation, NDJSON streaming, auth/rate-limit/SP19, 999/TA1/277CA parse endpoints, scheduler endpoints |
 | Backend fixture-driven | `pytest` (`tests/fixtures/*.txt`) | `backend/tests/test_prodfiles_smoke.py` | 113 + 19 + 1369 production files; round-trip property |
 | Backend SQL | `pytest` (in-memory SQLite) | `backend/tests/test_db*.py` | Schema, migrations, ORM, encryption round-trip |
 | Frontend unit | `vitest` (`*.test.ts(x)`) | `src/lib/`, `src/hooks/`, `src/components/ui/` | Pure functions, hooks, primitives |
 | Frontend component | `vitest` + Testing Library | `src/components/`, `src/pages/` | Drawers, lane rendering, drill stack, export buttons |
 | Smoke | manual / shell | `scripts/smoke.sh` (planned in SP23) | End-to-end parse → reconcile → export flow |
 ### 9.2 Fixture sources
 - `backend/tests/fixtures/minimal_*.txt` — minimal valid 270 / 271 / 277CA / 835 / 837P / 999 / TA1 / co_medicaid / unbalanced_835 — written by hand, used in unit tests.
 - `docs/prodfiles/claims/*.x12` (113 files) — real-looking production files used by `test_prodfiles_smoke.py` for the round-trip property.
 - `docs/prodfiles/FromHPE/` (1369 files) — full inbound directory from the production SFTP path.
 - `docs/prodfiles/837p-from-axiscare/` (19 files) — production 837Ps from AxisCare.
 - `docs/prodfiles/835fromco/` (5 files) — production 835s from CO Medicaid.
 ⚠ **PHI warning:** prodfiles contain real-looking patient data. Even in a single-operator tool, fixtures should be flagged as PHI (completeness review §3.2.23 — flagged but not yet actioned; for v1 they're kept under `docs/prodfiles/` with no additional access control).
 ### 9.3 Coverage goals
 - **Pure-function modules** (`reconcile`, `scoring`, `npi`, `cas_codes`, `parsers`, `edi.filenames`, `batch_diff`): ≥ 90% line coverage. `pytest-cov` is installed; the gate (`--cov-fail-under=90`) is **not enforced today** and is a round-3 backlog item.
 - **Store facade** (`store`, and the future `store_persistence / store_reconcile / store_queries / store_mappers` modules): every public method has at least one happy-path and one failure-path test.
 - **API routes**: every route has a happy-path test; error paths (404, 409, 413, 415, 422, 423, 429, 500) covered by at least one test each.
 - **Round-trip property** (SP8): 100% of `docs/prodfiles/claims/*.x12` must parse → serialize → parse to the same `claim_id`.
 - **Live tail** (SP5): one happy snapshot → live item → disconnect cleanup test per endpoint.
 ### 9.4 How to run
 ```bash
 # Backend
 cd backend
 .venv/bin/pytest                       # 964 tests collected (2026-06-23)
 .venv/bin/python -m cyclone serve
 # Frontend
 npm run typecheck
 npm test                                # 73 test files
 npm run build
 # Smoke (planned in SP23)
 bash scripts/smoke.sh
 ```
 ### 9.5 What is NOT covered (explicit)
 - **Component / E2E browser tests (Playwright).** Deferred; the local-only threat model doesn't justify them. (Completeness review §3.2 + SP23 §14.)
 - **Property-based tests** (Hypothesis) for the parser. Could add; not scheduled.
 - **Mutation tests** (mutmut / cosmic-ray). Not scheduled.
 - **Performance / load tests.** Single-operator scale; not scheduled.
 - **NPPES round-trip validation** (only Luhn checksum is covered; SP20).
 - **External-integration tests against the real Gainwell MFT.** The pipeline agent covers this in `cyclone-pipeline/`; out of scope for this repo.
 - **CI workflow.** Not present in the repo; release gating is manual today.

 ## 10. Assumptions
 Recorded explicitly so a new engineer can challenge any of them.
 | # | Assumption | If wrong, what changes |
 |---|---|---|
 | A1 | One operator, one host, one trading partner (CO Medicaid). | Multi-tenant / multi-payer scope would require SP23 + multi-payer NPI expansion + COB + AS2/AS4. |
 | A2 | The host runs macOS (Keychain via `keyring`) OR Ubuntu (Docker secrets available, SP23). | Linux-without-Docker / Windows would require a different secrets backend (`keyring` already dispatches via Secret Service / kwallet on Linux; Windows would use Credential Manager). |
 | A3 | The host is physically secure; LUKS / FileVault is the operator's concern, not Cyclone's. | If not, the SQLCipher-encrypted-DB posture is insufficient; per-file encryption of `prodfiles/` and `sftp_staging/` becomes mandatory. |
 | A4 | The operator can hand the 837 ZIP to the Gainwell MFT UI manually. | Removes the need for a built-in SFTP submit (SP13); the SFTP wire stays stub. |
 | A5 | The 835 lands the following Monday (CO Medicaid payment cycle) and is verified by a separate `check-835` subcommand (in `cyclone-pipeline/`), not inline. | Would require a different round-trip contract; affects SP22 pipeline agent. |
 | A6 | ICD-10 / HCPCS / NDC vocabulary is not Cyclone's responsibility. | Would require vendoring vocab CSVs and adding vocabulary checks (FR + tests). |
 | A7 | NPPES NPI registry lookup is not needed (offline Luhn is enough). | Would require scheduled NPPES download + online check + new FR. |
 | A8 | The X12 5010 transaction set Cyclone supports is sufficient for the operator's billing workflow. | Adding 837I / 837D / 278 / 276-277 / 277CA-round-trip / etc. is each a new SP. |
 | A9 | Local-only bind is sufficient — no remote access needed. | Would require auth (SP23), TLS, reverse proxy, RBAC. |
 | A10 | One Python process, no message broker, no separate worker. | A multi-worker deployment would require breaking thread-affinity (SP12/SP15 specifically). |
 | A11 | 964 backend tests + 73 frontend test files is the right test density for this codebase (2026-06-23). If we add more transaction types or surface area, this needs to grow proportionally; coverage gates should be enforced (round-3 backlog). | New transaction types or surface area without test growth → coverage drifts down. |
 | A12 | `cyclone-pipeline/` is a sibling project, not a sub-project of this repo. | The 7-phase round-trip agent is shipped in `cyclone-pipeline/`; if that project is abandoned, the manual operator workflow remains (upload via `/upload`, SFTP by hand, `check-835` not available). |

 ## 11. Risks and known gaps
 Pulled forward from [`docs/reviews/2026-06-20-cyclone-completeness-review.md`](reviews/2026-06-20-cyclone-completeness-review.md). Status as of 2026-06-23.
 | ID | Risk / gap | Source | Status |
 |---|---|---|---|
 | R-1 | No app-layer auth (anyone on the host can read PHI). | Completeness review §3.1.4 + §3.2.25 | **Closed by SP24** — auth shipped via the merge of `origin/main` on 2026-06-23 (commits `a25504b`..`39ae988`, `cyclone.auth.*` + `matrix_gate` dependency on every router); SP24 reconciled the docs to match. SP23 still covers the LAN-bind / Docker / RBAC product fork. |
 | R-2 | SQLite plaintext if SQLCipher not enabled. | Completeness review §3.1.1 | **Partial** — SP12 + SP15 ship the encryption option, but it falls back to plain if the Keychain entry is missing. |
 | R-3 | No Dockerfile / docker-compose.yml. | Completeness review §3.2.29 | **Open** — SP23 spec covers it but is awaiting user decision. |
 | R-4 | PayerConfig still partly in code (`co_medicaid()` factory at `cyclone/parsers/payer.py:57-58`). | Completeness review §3.1.9 | **Open** — SP9 externalized config but the factory remains as a fallback for tests and default-payer selection. |
 | R-5 | No vocabulary tables (ICD-10 / HCPCS / NDC). | Completeness review §3.1.11 | **Open** — explicitly out of scope per A6. |
 | R-6 | No COB / secondary-claim generator. | Completeness review §3.1.12 | **Open** — explicitly out of scope per §2.2. |
 | R-7 | No real-time eligibility round-trip. | Completeness review §3.1.8 | **Open** — 270/271 are file-exchange only per SP3. |
 | R-8 | No NPPES NPI lookup. | Completeness review §3.1.10 | **Open** — only Luhn checksum (SP20). |
 | R-9 | No 837I / 837D / 834 / 820 / 275 / 278 / 276-277 transaction types. | Completeness review §2.1 | **Open** — explicitly out of scope per §2.2. |
 | R-10 | Score weights hardcoded (`cyclone/scoring.py:42-46`). | Completeness review §3.1.15 | **Open** — not scheduled. |
 | R-11 | `cyclone/store.py` is a 2,172-line god-module. | Completeness review §3.1.17 | **In-flight** — SP21 spec + plan written; branch `refactor/store-split` exists; merge to `main` pending. |
 | R-12 | `cyclone/api.py` is a 3,145-line god-module (larger than `store.py`). | Completeness review §3.1.19 | **Partial** — `api_routers/` exists for 4 sub-routes (acks, admin, health, ta1_acks); bulk of routes still in `api.py`. |
 | R-13 | Migrations in flat dir without manifest. | Completeness review §3.1.18 | **Open** — no checksum list; 12 SQL files in `backend/src/cyclone/migrations/`. |
 | R-14 | No `pre-commit` / `Makefile` / `CONTRIBUTING.md` / `.editorconfig` / `ruff` config. | Completeness review §3.2.30 | **Open** — single-operator project. |
 | R-15 | No license file (`LICENSE`). | Completeness review §3.2.28 | **Open** — not scheduled. |
 | R-16 | PHI fixtures not flagged as PHI. | Completeness review §3.2.23 | **Open** — not scheduled. |
 | R-17 | `/api/health` not rich (before SP19). | Completeness review §3.2.24 | **Closed by SP19** — `api_routers/health.py:28-40` returns the rich snapshot via `get_health_snapshot()`. |
 | R-18 | No CSP / no security headers (before SP19). | Completeness review §3.2.25 | **Closed by SP19** — `SecurityHeadersMiddleware` in `cyclone/security.py`. |
 | R-19 | No request body size / rate limit (before SP19). | Completeness review §3.1.4 | **Closed by SP19** — `BodySizeLimitMiddleware` + `RateLimitMiddleware` in `cyclone/security.py`. |
 | R-20 | No 277CA support (before SP10). | Completeness review §3.1.7 | **Closed by SP10**. |
 | R-21 | No structured logging (before SP18). | Completeness review §3.1.5 | **Closed by SP18**. |
 | R-22 | No backup automation (before SP17). | Completeness review §3.1.3 | **Closed by SP17**. |
 | R-23 | `ActivityEvent` not tamper-evident (before SP11). | Completeness review §3.1.2 | **Closed by SP11** — but note: the tampered table is `audit_log`, distinct from `activity_events` (see NFR-3 / NFR-4). |
 | R-24 | SP23 product fork (auth + Docker + RBAC + LAN-bind). | §6.2 | **Awaiting user decision** — see §2.2 and §11 R-1. |
 | R-25 | `vitest@^4.1.9` is unusually new (current stable line is 1.x/2.x). | §5.3 | **Open** — verify the version pin is intentional before the next `npm install`; fallback to `^2.x` if accidental. |
 | R-26 | No CI workflow (`.github/workflows/`). | §8.1 #3 | **Open** — release gating is manual today. |
 | R-27 | `backend/src/cyclone/workflow/__pycache__/` is dead bytecode. | §5.1 | **Open** — recommend deletion. |

 ## 13. Reviewer checklist (for round 2 → round 3 closure)
 For the two independent reviewers at the end of round 2 (re-verifying the corrections):
 1. **Components** — Do §5.1 (backend modules) + §5.1 (frontend dirs) list every existing module that ships PHI or serves a state-changing route? Are the boundaries (DB / ORM / reconcile / store / api / pubsub / clearhouse / batch_diff / edi.filenames) drawn correctly? Can you, from §5.1 alone, draw the import graph?
 2. **Data model** — Are all 12 migrations listed in §5.2 with their purpose? Are the two worktree-only migrations (0013, 0014) flagged as in-flight? Are all 18 ORM models in §5.2? Is the `db_backups` (not `backups`) correction applied? Is the `Rejection` phantom removed? Is the `ActivityEvent` vs `AuditLog` distinction clear (NFR-3 vs NFR-4)?
 3. **Dependencies** — Are §5.3 runtime + tooling deps correct (no missing `pyyaml`, no missing `keyring`, no `httpx` listed as runtime, `paramiko` flagged as `[sftp]` extra, `sqlcipher3` flagged as `[sqlcipher]` extra, frontend test env is `happy-dom` not `jsdom`, vitest pinned at `^4.1.9` flagged as unusual)? Are OS-level deps (Keychain via `keyring`, SQLCipher C library, `tini`, `nginx` if SP23 ships) called out?
 4. **Definition of Done** — Is §8 testable? Project DoD #6 now points at the reviewer-agreement meta-criterion. Per-release + per-task DoDs each independently checkable? FR-7 / FR-33 traceability rows corrected to point at existing test files and the correct endpoint name?
 5. **Traceability** — Pick any FR-NN in §3. Can you trace it to an SP, a spec on disk (or an honest "no dedicated spec on disk" note), a plan on disk (or an honest "no plan file on disk; feat(spN) commits substitute" note), and at least one test file in `backend/tests/` or `src/`? If not, that's a remaining gap.
 6. **Assumptions** — Are §10 assumptions falsifiable? Could a new engineer challenge any of them and find the test that proves/disproves them? Is A2's reference to `keyring` accurate now?
 7. **Risks** — Are §11 risks current (R-11 corrected to 2,172; R-12 added; R-25/R-26/R-27 added)? Compare against `docs/reviews/2026-06-20-cyclone-completeness-review.md`. Is R-24 (SP23 fork) clearly flagged as awaiting user decision?
 If reviewers materially agree on all seven, round 2 closes; this doc becomes the project's new top-level entry point (linked from `README.md`).

 *End of round 2. Next: re-verify with reviewers (round 3) or escalate any remaining disagreement to the user.*

 # CSS Reduction — Baseline (2026-06-23)
 ## Goal
 Reduce `dist/assets/index-*.css` bytes without changing any tested screen.
 One declaration/rule at a time, verified by pixel-identical screenshots
 and project checks. This file is the baseline the iterative loop is
 compared against.
 ## Build (the size we are trying to shrink)
 | metric       | bytes  |
 | ------------ | ------ |
 | raw          | 60,695 |
 | gzip         | 11,786 |
 | brotli       |  9,875 |
 `dist/assets/index-BznqBut5.css`, built with `npx vite build` (Vite 5.4.21,
 8.9s).
 ## Test matrix (the screens we will hold pixel-identical)
 - **Theme**: dark only (the app is `<html class="dark">` + `theme="dark"`
  for the Toaster; no light path exists in the design system).
 - **Sizes**: 3 (desktop 1440×900, tablet 768×1024, mobile 375×812).
 - **Routes**: 13 (`/`, `/upload`, `/inbox`, `/claims`, `/claims?status=denied`,
  `/remittances`, `/providers`, `/reconciliation`, `/acks`, `/batches`,
  `/batch-diff`, `/activity`, `/does-not-exist`).
 - **Interactive states**: 6 (claim drawer open, remit drawer open, inbox
  row focused, search focused, keyboard cheatsheet open, upload dropzone
  focused) × 3 sizes = 18 captures.
 - **Total**: 13 × 3 + 6 × 3 = **57 screenshots** per build.
 Capture source: `audit-uiux-extended.mjs` (new, superset of
 `audit-uiux.mjs`). Pixel-diff harness: `tools/css-screenshots-diff.mjs`
 using `pixelmatch` (threshold 0).
 ## Project checks (the gates we hold green)
 | check                       | baseline | used as gate? | reason                                  |
 | --------------------------- | -------- | ------------- | --------------------------------------- |
 | `npx vite build`            | passes   | **yes**       | produces the CSS bundle under reduction |
 | `npx vitest run`            | 498 / 501 | **yes**       | pre-existing 3 failures, see "Known failures" below |
 | `tsc -b` (in `npm run build`)| **fails**| no            | 15 type errors in test files + `Upload.tsx`, all pre-existing |
 | `npm run typecheck`         | fails    | no            | same as above                           |
 | `npm run lint`              | fails    | no            | `sh: eslint: command not found` (eslint not installed) |
 ### Known pre-existing failures (not caused by this work)
 `vitest run` — 3 failing tests:
 - `src/pages/Inbox.test.tsx > Inbox page > SP14: payer-rejected row count rolls up into the need-eyes header`
 - `src/store/tail-store.test.ts > useTailStore > test_fifo_cap_evicts_oldest_when_over_10000`
 - `src/components/inbox/InboxHeader.test.tsx > InboxHeader > renders the date and counts`
 None touch CSS. Each candidate run will compare the new `vitest` exit
 status and failure set to the baseline — a candidate is rejected if it
 adds a new failure, even if the count stays at 3.
 `tsc -b` / `npm run typecheck` — 15 errors in test files and
 `src/pages/Upload.tsx`. Not exercised by the reduction loop.
 `npm run lint` — `eslint` is not installed in `devDependencies`; the
 script `npm run lint` exits 127. Not exercised.
 ## Interactive-state coverage
 Out of 18 interactive captures, 15 succeed and 3 fail (the same 3 every
 run):
 - `remittances-drawer` × all sizes — the `/remittances` page renders with
  no table rows in the current backend state, so the row-click step finds
  nothing. The screenshot falls back to the static `/remittances` page
  with no drawer; pixel-identical comparison still works for that
  fallback, but the remittance-drawer CSS itself is not exercised. This
  is captured here as an **untested state** for the final report.
 The other 15 interactions (`claims-drawer`, `inbox-row-focused`,
 `search-focused`, `cheatsheet-open`, `upload-dropzone-focused` × 3 sizes)
 all succeed. They exercise the CSS for the open claim drawer, the
 keyboard cheatsheet overlay, the focused search button, the focused
 upload dropzone, and the focus ring on inbox rows.
 ## Pre-existing noise (not regressions, not caused by this work)
 From the baseline run (`baseline-report.json`):
 - 6/57 flows have ≥1 console error. All from the `inbox` route and the
  `inbox-row-focused` state. The 4 interactive ones are the same
  source.
 - 24/57 flows have ≥1 failed request. Likely the dashboard summary
  endpoint (`/api/dashboard/summary`) and a few analytics / SSE probes
  in the inbox.
 - 0 page errors.
 A candidate that does not increase these counts is fine; an increase
 is informational, not a gate.
 ## Self-diff sanity check
 `tools/css-screenshots-diff.mjs compare` with `BASE == CAND` returns
 `PIXEL-IDENTICAL — 57 compared, 0 differing`. The harness works.
 ## What is in scope for the iterative loop
 - Source: `src/index.css` (custom CSS + Tailwind base/components/utilities)
 - Config: `tailwind.config.js`
 - Component `.tsx` files (only if removing a Tailwind utility from a
  `className` produces a smaller bundle)
 ## What is out of scope
 - `index.html` (Google Fonts preconnect, hard to prove pixel-identical
  after font source change)
 - The JS bundle (separate goal)
 - The backend (`backend/`)
 - Any non-CSS build artifact

 # CSS Reduction — Candidate Queue
 Atomic removals to try, in priority order. Each is one revertable unit
 (edit one file, revert if pixel-identical or project checks regress).
 Priority legend: **H** (high confidence, no visible effect expected),
 **M** (medium, may affect pixels in edge cases), **L** (low, will likely
 revert because it changes visible output).
 | # | priority | id | what | where | expected | notes |
 |---|----------|----|------|-------|----------|-------|
 | 1 | H | `var-surface-line-soft` | drop the `--surface-line-soft` declaration | `src/index.css` line 77 | ~30 B | Only mentioned in a comment in `BarChart.tsx`; no `var(--surface-line-soft)` ref anywhere |
 | 2 | H | `var-m-error-bg` | drop the `--m-error-bg` declaration | `src/index.css` line 102 | ~30 B | No `var(--m-error-bg)` ref anywhere in src |
 | 3 | H | `kf-fade-in-soft` | drop `fade-in-soft` keyframe + `animate-fade-in-soft` util | `tailwind.config.js` | ~150 B | `animate-fade-in-soft` is not used in any source file |
 | 4 | H | `kf-slide-in-right` | drop `slide-in-right` keyframe + animation | `tailwind.config.js` | ~180 B | `animate-slide-in-right` not used |
 | 5 | H | `kf-ticker-blink` | drop `ticker-blink` keyframe + animation | `tailwind.config.js` | ~200 B | `animate-ticker-blink` not used |
 | 6 | H | `kf-accordion-down` | drop `accordion-down` keyframe + animation | `tailwind.config.js` | ~150 B | `animate-accordion-down` not used; no accordion in app |
 | 7 | H | `kf-accordion-up` | drop `accordion-up` keyframe + animation | `tailwind.config.js` | ~150 B | same as above |
 | 8 | H | `media-print` | drop the entire `@media print { ... }` block | `src/index.css` lines 402–446 | ~1 KB | Print not in test matrix; the `display: none` rules apply to aside/header — they don't appear in screenshots anyway. **Risk**: a printed detail drawer would no longer be styled for paper, but no print preview is captured. |
 | 9 | M | `body-before` | drop the `body::before` radial gradients (the upper-right accent + top-center softbox) | `src/index.css` lines 147–156 | ~400 B | Subtle background. Likely visible on all screenshots. **Will likely revert.** |
 | 10 | M | `body-after` | drop the `body::after` hairline grid | `src/index.css` lines 163–176 | ~450 B | Subtle background grid. Likely visible. **Will likely revert.** |
 | 11 | M | `scrollbar` | drop `::-webkit-scrollbar*` rules | `src/index.css` lines 179–195 | ~330 B | Scrollbars only visible when content overflows. Most screenshots are above-the-fold; may not trigger. |
 | 12 | M | `nav-active-before` | drop the `::before` accent strip on `.nav-active` | `src/index.css` lines 290–300 | ~180 B | Visible on the active sidebar item. |
 | 13 | M | `surface-2` | drop the `.surface-2` class entirely | `src/index.css` lines 266–277 | ~250 B | Used in some components — likely a revert. |
 | 14 | M | `focus-visible` | drop the global `:focus-visible` ring | `src/index.css` lines 200–204 | ~90 B | All focusable elements would lose the global ring (but Tailwind focus-visible: utilities still apply). May or may not change pixels. |
 | 15 | L | `body-bg-image` | drop the body background-image gradients | `src/index.css` lines 136–139 | ~250 B | **Will revert** — visible. |
 | 16 | L | `skip-link` | drop the `.skip-link` class | `src/index.css` lines 303–338 | ~700 B | Component exists (`ui/skip-link.tsx`). Removing the class breaks it visually. **Will revert.** |
 | 17 | L | `drillable` | drop `.drillable` and its hover | `src/index.css` lines 449–461 | ~220 B | Used in `DrillableCell.tsx`. **Will revert.** |
 | 18 | L | `row-hover` | drop the `.row-hover` hover state | `src/index.css` lines 379–384 | ~100 B | Used in tables. Hover state not captured (no mouse). Could be safe. |
 ## Out of scope (intentionally not tried)
 - Tailwind preflight (`*, ::before, ::after`, `::backdrop` with `--tw-*` vars). These power the utility system; removing would break all utilities.
 - `@media (prefers-reduced-motion)`. Safety block, removing would change behavior in non-default OS settings.
 - Specific custom class definitions that are heavily used (`.num`, `.display`, `.mono`, `.surface`, `.eyebrow`, `.editorial`).
 - Any Tailwind utility removal in component `className` props (small wins, lots of churn — would be done in a follow-up pass).
 - The `index.html` Google Fonts `<link>` (it's HTML, not CSS, and removing it would change the rendered output).
 ## Stopping conditions
 - Queue exhausted.
 - 5 consecutive candidates fail the **size** check (CSS not smaller after the change).
 - 2 hours elapsed in Phase 3.
 - User requests a stop.

 # Cyclone Documentation Review — Reviewer A
 ## 1. Reviewer identity
 **Reviewer A** (Reviewer B is run in parallel; this review covers the full doc set + codebase ground-truth verification).
 ---
 ## 2. Executive summary
 Cyclone's documentation is unusually thorough for a single-operator tool: a top-level `REQUIREMENTS.md` (38 FRs + 18 NFRs), a top-level `ARCHITECTURE.md`, 27 design specs (20 dated 2026-06-19 to 2026-06-22 + 7 backfilled 2026-06-23 for SP10–SP16), and 27 implementation plans (15 original + 12 backfilled for SP9–SP20). The doc set has the structure of a well-run engineering project, and the prose quality is high — every spec re-asserts the local-only/single-operator/single-payer design contract, every plan has TDD discipline, and the layering (requirements → architecture → spec → plan → tests) is internally consistent at a high level. **However, the doc set has accumulated at least 25 specific contradictions, ambiguous forks, untested artifacts, and stale numbers** between the two top-level docs alone — and the contradictions are concentrated in the most consequential areas: the live-tail HTTP surface, the claim-state machine, and the LOC/version counters used in the verification matrix. The 7-state claim lifecycle is wrong in 5 places; the codebase has an 8-state enum (`backend/src/cyclone/db.py:180-188`). The tail endpoint URL is `/api/{resource}/stream` per REQUIREMENTS FR-20 + the live-tail spec, but `/api/tail?since=…` per `ARCHITECTURE.md` §5.4 — two competent engineers reading only the docs could ship two incompatible APIs. Below, the 4 reviewer questions and 4 flag sections detail every issue with file:line citations.
 ---
 ## 3. Q1: Components
 ### Description
 Cyclone is composed of six concentric layers: (1) the SQLite/SQLCipher store at the bottom (`backend/src/cyclone/db.py`, `backend/src/cyclone/db_crypto.py`, migrations 0001–0012), (2) ORM models and pure-function business logic (`db.py`, `reconcile.py`, `scoring.py`, `npi.py`, `cas_codes.py`, `inbox_lanes.py`, `inbox_state.py`, `inbox_state_277ca.py`, `audit_log.py`), (3) the per-parser modules under `parsers/` (16 files including the 270/271/277CA/835/999/TA1/837P parsers and serializers), (4) the persistence facade `store.py` (CycloneStore) plus per-feature handlers (`scheduler.py`, `backup_service.py`, `backup_scheduler.py`, `logging_config.py`, `security.py`, `pubsub.py`, `clearhouse/__init__.py`, `providers.py`, `payers.py`), (5) the FastAPI surface — a monolithic `api.py` (~3,548 LOC per ARCHITECTURE §3.1 / 3,145 per REQUIREMENTS) plus a partial `api_routers/` package (`acks.py`, `admin.py`, `health.py`, `ta1_acks.py`) that owns the new admin/health endpoints, and (6) the React + Vite + TypeScript frontend (`src/`) with TanStack Query v5, Zustand, Radix UI primitives, and shadcn-style components.
 The top-level docs (`REQUIREMENTS.md` §2.1, `ARCHITECTURE.md` §3) describe these layers at the same level of granularity and agree on the boundaries. The cross-SP doc set reinforces them: each spec names the modules it extends (e.g. SP13 `clearhouse/__init__.py:319`, SP14 `inbox_lanes.compute_lanes`, SP15 `db_crypto + db + api`, SP16 `scheduler.py:720`). The ASCII topology diagram in `ARCHITECTURE.md` §1.2 is the canonical picture.
 ### Consistency verdict
 **Mostly consistent, with three meaningful gaps:**
 1. The `api_routers/` package is partially implemented (`acks.py`, `admin.py`, `health.py`, `ta1_acks.py`) but documented only as "planned" in `ARCHITECTURE.md` §3.2 and not mentioned at all in `REQUIREMENTS.md`; the specs still reference monolithic `cyclone.api` (e.g. SP15 §3.3 says `cyclone/api.py:2797-2928` for the rotation endpoint, but the actual code lives at `api_routers/admin.py`). Engineers building "what does Cyclone's API look like" from the spec set will get the monolithic picture; engineers reading the codebase will see a partially split package.
 2. `backup.py` (file upload/retention module) and `backup_service.py` vs `backup_scheduler.py` (periodic scheduler) are described as a single "SP17" subsystem across the docs, but the spec file (`2026-06-21-cyclone-encrypted-backup-design.md`) is the *original* SP17 spec while the implementation plan is dated `2026-06-23-cyclone-sp17-encrypted-backup.md`. The two documents describe the same work but the round-3 doc-prep added the plan but did NOT add a backfilled spec for SP17. So the SP17 docs are pre/back mixed, not a clean backfill like SP10–SP16 (which got both spec and plan).
 3. The `workflow/` subdirectory visible under `backend/src/cyclone/` has only `__pycache__/` entries on disk (`workflow/__pycache__/__init__.cpython-313.pyc`, `workflow/__pycache__/batch_diff.cpython-313.pyc`, `workflow/__pycache__/inbox_lanes.cpython-313.pyc`, `workflow/__pycache__/inbox_state.cpython-313.pyc`, `workflow/__pycache__/reconcile.cpython-313.pyc`, `workflow/__pycache__/scoring.cpython-313.pyc`) — but no `.py` source files. This indicates `workflow/` was a refactoring target (likely SP21 store-split) whose sources were removed/moved but whose compiled artifacts were not cleaned. **None of the docs mention `workflow/` as a deprecated stub**; engineers reading the docs will not understand why the directory exists in compiled form only.
 **Verdict: medium confidence in component consistency.** The high-level decomposition is consistent across the top-level docs and the spec set. The drift is in the partial-API-router split, the SP17 plan/spec asymmetry, and the unexplained `workflow/` ghost directory.

 ## 4. Q2: Data model
 ### Description
 The data model is a SQLAlchemy 2.0 ORM (`backend/src/cyclone/db.py`) backed by SQLite, optionally encrypted via SQLCipher (`backend/src/cyclone/db_crypto.py` — SP12). Migration runner is `db_migrate.py` reading `PRAGMA user_version` — **12 migrations on disk**: `0001_initial` through `0012_backups` (listed at `backend/src/cyclone/migrations/`). The core tables are: `batches`, `claims`, `remittances`, `cas_adjustments`, `matches`, `activity_events`, `service_lines`, `service_line_payments`, `line_reconciliations`, `acks`, `ta1_acks`, `providers`, `payers`, `clearhouse`, `payer_rejected` columns on `claims` (SP10, migration 0008), `payer_rejected_acknowledged_at`/`_actor` (SP14, migration 0010), `audit_log` (SP11, migration 0009), `processed_inbound_files` (SP16, migration 0011), and `backups` (SP17, migration 0012).
 The key entity relationships are: `Batch 1—N Claim`, `Batch 1—N Remittance`, `Remittance N—1 Claim` (nullable FK on `claims.matched_remittance_id`), `Remittance 1—N CasAdjustment`, `Claim 1—1 Match` (unique), `Claim 1—N ServiceLine`, `Remittance 1—N ServiceLinePayment`, `Claim 1—N LineReconciliation`, `Remittance 1—N LineReconciliation`, and `AuditLog` as a chain on its own (no FKs; the chain links by `prev_hash`). `ServiceLinePayment` is the SP7 bridge between the 837 and 835 line worlds; it carries the `procedure_code`/`service_date`/`charge`/`payment`/`units` plus `modifiers_json` as a serialized list. The `audit_log` table (SP11) is a separate hash-chained append-only log keyed by SHA-256 of `(event_type, entity_type, entity_id, actor, created_at, prev_hash)`; the chain is verifiable via `cyclone.audit_log.verify_chain(session)` (verified at `backend/src/cyclone/audit_log.py:190`) which recomputes every hash and walks the `prev_hash` links (`audit_log.py:228-242`).
 The state machine has multiple representations in the docs:
 - **`REQUIREMENTS.md` §3.1 + §6.3 (traceability)** says: "7-state claim lifecycle: submitted, received, paid, partial, denied, reconciled, reversed."
 - **`backend/src/cyclone/db.py:180-188` (code)** says: `ClaimState` enum with **8 values**: `SUBMITTED, RECEIVED, REJECTED, PAID, PARTIAL, DENIED, RECONCILED, REVERSED`. The 8th state, `REJECTED`, was added by the workflow-automation/SP6 plan (`docs/superpowers/plans/2026-06-20-cyclone-workflow-automation.md` Task 1) when 999 AK9 R/E rejection handling was introduced.
 - **`ARCHITECTURE.md` §6.3** says: "states: submitted, accepted, paid, denied, appealed, rejected, payer_rejected" — 7 states, including `accepted` (which is NOT in the code) and `payer_rejected` (which is NOT a state in the code but a set of columns on `claims` filtered on by `inbox_lanes.compute_lanes`).
 - **`docs/superpowers/specs/2026-06-19-cyclone-db-reconciliation-design.md` §6.7** (pre-SP6) says: "submitted, received, paid, partial, denied, reconciled, reversed" — 7 states, matches the pre-SP6 plan.
 The `payer_rejected` status is *not* a `ClaimState` value. It is stored as four columns on `claims`: `payer_rejected_at`, `payer_rejected_reason`, `payer_rejected_status_code`, `payer_rejected_by_277ca_id` (verified at `backend/src/cyclone/db.py:270-280`; SP10 spec §2.1). The 5th inbox lane (`payer_rejected`) is computed by `inbox_lanes.compute_lanes` filtering on `payer_rejected_at IS NOT NULL AND payer_rejected_acknowledged_at IS NULL` (SP14 spec §3.2). So `payer_rejected` is a *view*, not a *state* — yet `ARCHITECTURE.md` lists it as a state.
 The `Match` model carries an `is_reversal` flag (defined in the SP2 plan) and the spec calls for a `state_before_reversal` column on `claims` to preserve reversals (`db_reconciliation-design.md` §6.6). The 835 reverse-direction (CLP02 ∈ {21, 22}) is handled by `apply_reversal()` in `reconcile.py` which restores the prior state. **However, the SP10 277CA path does NOT extend the state machine** — claims with a payer rejection stay in their prior state (`paid`, `denied`, `partial`, etc.) and gain the `payer_rejected_at` timestamp; the 5-lane inbox surfaces them but `claim.state` does not transition to a new value. This is consistent with the SP10 spec §2.3 ("we explicitly do not clear `payer_rejected_at` on acknowledge") and SP14 spec §2.3, but contradicts the more casual phrasing in `ARCHITECTURE.md` §6.3.
 ### Consistency verdict
 **Low confidence in data-model consistency across the doc set.** The `ClaimState` enum has 8 values (verified at `backend/src/cyclone/db.py:180-188`) but the docs claim 7 in 4 places (`REQUIREMENTS.md` §3.1 and §6.3, `ARCHITECTURE.md` §6.3, the db-reconciliation spec §6.7, and the workflow-automation plan Task 1 implicitly). The 5th `payer_rejected` "state" in `ARCHITECTURE.md` §6.3 is not a state in the code — it is a column-and-filter view. Engineers building the data model from the docs alone will produce either an 8-state enum without a `payer_rejected` value (correct) or a 9-state enum with both `rejected` and `payer_rejected` (wrong, not in the code).
 The second meaningful gap is the dual audit mechanism. `activity_events` (db.py original migration 0001) is a regular table for *transition events*; `audit_log` (SP11, migration 0009) is a separate hash-chained table for *HIPAA-relevant events*. The docs are inconsistent on which events go where: the SP14 spec §3.3 says `claim.payer_rejected_acknowledged` is appended to `audit_log`, but the SP6 workflow plan implies `claim.rejected` (the 999 R/E event) lands in `activity_events`. The two tables overlap in name space but have different writers — `audit_log.py:99-126`'s `append_event` takes an `AuditEvent` payload but `activity_events` is written from a different code path (`store.py`). No doc explicitly enumerates which `kind` strings go to which table.

 ## 5. Q3: Dependencies
 ### Description
 There are four overlapping dependency graphs in this doc set: (a) spec-level dependencies ("depends on SP X"), (b) plan-level task dependencies (TDD phases 1 → 2 → 3 with `git worktree` rebases), (c) module/import dependencies in the codebase, and (d) data-model migration ordering. The graphs mostly agree; the divergences are concentrated in SP21/SP22 (in-flight) and SP23 (candidate).
 **(a) Spec dependencies.** The 7 backfilled specs (SP10–SP16) each declare their upstreams explicitly:
 - SP10 (277CA) `2026-06-23-cyclone-sp10-277ca-payer-rejected-design.md` §"Depends on:" → SP3 (999 parser) + SP6 (workflow/inbox).
 - SP11 (audit log) → SP6 + SP10 + SP12.
 - SP12 (SQLCipher) → standalone.
 - SP13 (SFTP) → SP9 (SftpClient stub + secrets).
 - SP14 (5-lane inbox) → SP6 + SP10 + SP11.
 - SP15 (key rotation) → SP11 + SP12 (cannot ship without SP12; `2026-06-23-cyclone-sp15-key-rotation-design.md` line 11: "Cannot ship without SP12").
 - SP16 (MFT polling) → SP9 + SP11 + SP13 + SP15 (implicitly, since SFTP auth uses the Keychain) + the per-parser modules.
 These declarations are consistent with the implementation order in the git log (SP10 → SP11 → SP12 → SP13 → SP14 → SP15 → SP16) and with the migration versions (0008 through 0011).
 **(b) Plan-level task dependencies.** The plans use a `[ ] Step N → commit` pattern with explicit prerequisites (e.g. `live-tail.md` Task 0 requires SP5 to be merged first; `claims-unique-constraint-and-409-ux.md` worktree setup requires `pip install -e backend`). The plan-level dependencies are clean within each plan; the cross-plan dependencies are weak. For example, the SP14 plan does not declare it depends on SP10's migration `0008_payer_rejected_columns.sql` — it just references "the SP10 `payer_rejected_*` columns" without naming the migration.
 **(c) Module dependencies.** The import graph in `backend/src/cyclone/` shows the expected layering: `parsers/` modules import `cyclone.exceptions` and `cyclone.segments` only (clean isolation); `db.py` imports nothing from `cyclone.*` (forward references via string IDs); `reconcile.py`, `scoring.py`, `inbox_lanes.py` import `cyclone.db`; `store.py` imports everything (`db`, `reconcile`, `scoring`, `inbox_state`, `inbox_state_277ca`, `pubsub`); `api.py` imports `store`, `db`, `audit_log`, `scheduler`, `db_crypto`, `security`, etc. The `scheduler.py` module *intentionally duplicates* small helpers (`_ack_count_summary`, `_ack_synthetic_source_batch_id`, `_277ca_synthetic_source_batch_id`) to break what would otherwise be a circular dependency with `cyclone.api` — this is documented in SP16 spec §3.5. The `audit_log.py:99-126` `append_event` function takes a session and an `AuditEvent`, called by SP14 ack endpoint, SP15 rotation endpoint, and SP16 scheduler handlers. The store-scheduler boundary is clean.
 **(d) Migration ordering.** 12 migrations on disk (`0001_initial` through `0012_backups`) are forward-only via `PRAGMA user_version`. The runner (`db_migrate.py`) reads `-- version: N` headers, sorts by filename, applies any with `version > current` (`db_migrate.py:438-466`). The version assertions in `test_db_migrate.py` confirm monotonic ordering. The `claims-unique-constraint-and-409-ux.md` plan adds migration `0013_drop_claims_unique_constraint.sql` on a worktree (`claims-unique-fix`); this migration does NOT exist on `main` yet, which is consistent with the plan being in-flight. **However, the `2026-06-23-cyclone-sp11-hash-chained-audit-design.md` spec refers to migration `0009_audit_log.sql` and the docs say SP11 ships migration 0009 — that migration IS on disk and `audit_log.py` exists, confirming SP11 shipped.**
 **(e) SP21 / SP22 / SP23 status.** SP21 (store split) is in-flight on `refactor/store-split` branch (`docs/superpowers/specs/2026-06-21-cyclone-store-split-design.md` Status: "Draft / not merged"); SP22 (parse-decide) lives on `claims-unique-fix` worktree (`docs/superpowers/specs/2026-06-21-cyclone-parse-decide-workflow-design.md` + the unique-constraint plan). SP23 (Ubuntu Docker + RBAC) is a candidate only (`docs/superpowers/specs/2026-06-22-cyclone-ubuntu-docker-deployment-design.md` Status: "Draft / candidate"). These are called out in the spec titles, but the top-level docs (`REQUIREMENTS.md` §1.4, `ARCHITECTURE.md` §0.1) do NOT explicitly mark SP21/SP22/SP23 as in-flight. An engineer reading only the top-level docs would assume all 23 SPs are at the same ship-readiness level.
 ### Consistency verdict
 **High confidence within the shipped SPs (SP1–SP20)**, where the spec→plan→code→migration→test graph is internally consistent. **Low confidence for SP21/SP22/SP23**, which are in-flight or candidate and not marked as such in the top-level docs. The spec-level "Depends on" declarations are accurate and actionable.

 ## 6. Q4: Definition of done
 ### Description
 `REQUIREMENTS.md` §8 (lines 643–681) defines "Definition of Done" in three sub-sections: §8.1 *Functional DoD* (every FR covered by ≥1 spec + ≥1 plan + ≥1 integration test), §8.2 *Non-Functional DoD* (every NFR has a verification command), §8.3 *Operational DoD* (deployment posture, backup readiness, encryption posture). Each FR has a row in the §6.1 traceability matrix pointing at the covering spec/plan and a test file. `ARCHITECTURE.md` §10 ("Operational Story") describes the deploy / backup / runbook posture in narrative form.
 The §8.1 Functional DoD says every FR is "Met" if it has a covering spec, plan, and integration test. The §6.1 traceability matrix marks FR-1 through FR-38 with a single test file each (e.g. FR-20 → `test_api_stream_live.py` + `TailStatusPill.test.tsx`). The matrix does NOT explicitly require happy-path AND failure-path test coverage — but `REQUIREMENTS.md` §4 NFR-2 ("Test discipline: every route has a happy-path test and at least one failure-path test") adds this requirement at the NFR layer. So the union of FR + NFR DoD is: each route has a happy + failure path test.
 The DoD is *partially testable*: the test-file pointers in the traceability matrix are verifiable by `ls backend/tests/` and `ls src/**/*.test.ts*`; the happy/failure-path test count is verifiable by reading each test file. The encryption-at-rest posture (NFR-5 / SP12) is verifiable by checking that `cyclone.db_crypto.is_encryption_enabled()` returns `True` when `sqlcipher3` is installed and the Keychain entry exists (per the SP12 spec §1). The single-process posture (NFR-14) is verifiable by reading the scheduler module's lack of `threading.Thread` / `multiprocessing.Process` callers. The audit-chain integrity (NFR-4 / SP11) is verifiable by `GET /api/admin/audit-log/verify` returning `ok: true, checked: N+1`.
 ### Testability verdict
 **Medium confidence.** Four issues break testability:
 1. The `REQUIREMENTS.md` §8.3 Operational DoD mentions "Vitest ^4.1.9" and flags it in §5.3 / R-25 as "unusually new — verify the version pin is intentional before the next npm install; fallback to `^2.x` if accidental." The `ARCHITECTURE.md` §3.2 (tooling table) lists `vitest 4.1.9` without flagging it. **The flagging is inconsistent — one top-level doc treats it as a problem to fix, the other treats it as normal.** A CI gate that asserts "vitest@^2.x" would fail on the codebase.
 2. The §8.3 DoD claims `vitest@^4.1.9` is "unusually new (current stable line is 1.x/2.x)" — but Vitest 4.x *does exist* (released after Vitest 3.x in 2025); the claim is also inaccurate relative to the doc's own date. The §6.3 acceptance row for SP5 says the live-tail test count target was "~144 frontend pass" with "~437 backend" — but `backend/tests/` contains 94 test files (verified by directory listing). The number is in the right order of magnitude but unverified.
 3. The §10 Operational Story in `ARCHITECTURE.md` describes "5-second heartbeat" on the live-tail stream — but `REQUIREMENTS.md` §4 NFR-10 (line 163) says "Heartbeat every 15s default (`CYCLONE_TAIL_HEARTBEAT_S`)". The actual `backend/src/cyclone/api.py:1679-1680` comment says `CYCLONE_TAIL_HEARTBEAT_S` (consistent with REQUIREMENTS, not ARCHITECTURE). **The 5s heartbeat claim is wrong against both the codebase AND REQUIREMENTS.md.** The operational story in §10 cannot be the basis for a deploy runbook until this is corrected.
 4. The §10 Operational Story does not describe the SP16 scheduler (`CYCLONE_SCHEDULER_AUTOSTART` opt-in, `CYCLONE_SCHEDULER_POLL_SECONDS` default 60) at all — only the manual operator path. The §8.3 DoD also does not mention "scheduler running without `CYCLONE_SCHEDULER_AUTOSTART=true`" as a verified-state precondition. The "auto-poll" deploy posture introduced by SP16 is invisible to the top-level DoD.
 **Verdict:** The DoD is *partially* testable. The functional DoD (each FR → test file) is verifiable by file enumeration. The non-functional DoD (each NFR → verification command) is mostly verifiable but the Vitest version flag, the heartbeat interval, and the scheduler autostart posture create 3 places where a competent engineer reading only the top-level docs would either install the wrong version or deploy the wrong polling config.
 ---
 ## 7. Contradictions
 The following are direct contradictions in the doc set. Each cites file:line for both sides.
 1. **`api.py` LOC count.** `REQUIREMENTS.md` §3.2 / R-23 says `api.py` is **3,145 LOC**. `ARCHITECTURE.md` §3.1 says `cyclone.api:app` is **3,548 LOC** with `cyclone.store` at **2,423 LOC**. `REQUIREMENTS.md` R-24 says `store.py` is **2,172 LOC**. Three different numbers for two files.
 2. **`store.py` LOC count.** Same as above: 2,172 (REQUIREMENTS R-24) vs 2,423 (ARCHITECTURE §3.1).
 3. **Live-tail heartbeat interval.** `REQUIREMENTS.md` §4 NFR-10 (line 163): "Heartbeat every 15s default (`CYCLONE_TAIL_HEARTBEAT_S`)". `ARCHITECTURE.md` §5.4: "5s heartbeat" (in the description of the live-tail stream). Code (`backend/src/cyclone/api.py:1679-1680`): "every `CYCLONE_TAIL_HEARTBEAT_S` seconds when idle". The `live-tail` plan (§7 / Phase 3 Task 11) says "the 15s heartbeat via `asyncio.wait_for` loop (overridable for tests)". **The 5s claim is wrong; the code and NFR-10 agree on 15s.**
 4. **Live-tail endpoint URL.** `REQUIREMENTS.md` §3.1 FR-20 (line 128) says `/api/{claims,remittances,activity}/stream`. `ARCHITECTURE.md` §5.4 says `GET /api/tail?since=…`. The `live-tail` spec (`2026-06-20-cyclone-live-tail-design.md`) and plan (`2026-06-20-cyclone-live-tail.md`) use the per-resource URL pattern. The code (`api.py:1679-1680`) matches the per-resource pattern. **The ARCHITECTURE §5.4 single-endpoint claim is wrong.**
 5. **Claim lifecycle state count.** `REQUIREMENTS.md` §3.1 + §6.3 traceability: "7-state claim lifecycle". `ARCHITECTURE.md` §6.3: "7 states: submitted, accepted, paid, denied, appealed, rejected, payer_rejected". Code (`backend/src/cyclone/db.py:180-188`): **8 states** (SUBMITTED, RECEIVED, REJECTED, PAID, PARTIAL, DENIED, RECONCILED, REVERSED). The docs disagree with themselves and with the code.
 6. **Claim lifecycle state names.** `ARCHITECTURE.md` §6.3 lists `accepted` and `appealed` — neither exists in the code or any spec. The code uses `RECEIVED` (not `accepted`) and has no `appealed` state. The lifecycle spec says reversal preserves the prior state via `state_before_reversal`; there is no appeal flow.
 7. **`payer_rejected` as a state.** `ARCHITECTURE.md` §6.3 lists it as a state. The SP10 spec §2.3 and SP14 spec §2.3 explicitly state `payer_rejected_at` is a timestamp column on `claims`, NOT a `ClaimState` value. The lane filter (SP14 spec §3.2) is `payer_rejected_at IS NOT NULL AND payer_rejected_acknowledged_at IS NULL`. **A lane is not a state.**
 8. **Vitest version flagging.** `REQUIREMENTS.md` §5.3 R-25 (line 652) flags `vitest@^4.1.9` as "unusually new" and a fallback to `^2.x` is suggested. `ARCHITECTURE.md` §3.2 lists `vitest 4.1.9` in the tooling table without any flagging. Engineers reading only the architecture doc will not realize the version is under review.
 9. **Plan ID numbering.** The user's plan inventory says "15 original plans + 12 backfilled plans = 27 plans". The on-disk count matches (15 + 12). But the original plans use a SP-numbering scheme ("Sub-project 4", "Sub-project 6", "Sub-project 7") while the backfilled plans use a `sp9`–`sp20` naming scheme. There is no `sp1`–`sp8` backfill because those SPs were the originals. **Engineers searching for "SP7 plan" find `2026-06-20-cyclone-line-reconciliation.md` (Sub-project 7) — works — but searching for "SP8 plan" finds `2026-06-20-cyclone-serialize-837.md` whose own title says "Sub-project 7" (the file was re-purposed from SP7 to SP8).** Both top-level docs note this self-acknowledged mis-labeling (`REQUIREMENTS.md` §1.4 + R-22 + `ARCHITECTURE.md` §0.1 mention it) but do not fix it on disk.
 10. **SP number ↔ filename mapping.** SP9 = `multi-payer-npi-sftp` (spec is "SP9 — Multi-payer NPI + SFTP"). But the user's plan inventory says "12 backfilled plans (dated 2026-06-23-cyclone-sp{9..20}-*.md)" — SP9 is the *first* backfilled. The original spec for SP9 lives at `2026-06-20-cyclone-multi-payer-npi-sftp-design.md` (not in the backfill range). So SP9 has an original spec + a backfilled plan + a backfilled spec for SP13-SFTP. The mapping is "SP9 = NPI + SFTP" but the "SFTP" name also gets re-used for SP13's `SftpClient` paramiko wire-up. **Two SPs share the SFTP concept; SP9 = config/secrets, SP13 = transport. The docs do not always disambiguate.**
 11. **SP17 spec/plan asymmetry.** SP17 (encrypted backup) has a spec file dated `2026-06-21` (the original) but the plan is dated `2026-06-23-cyclone-sp17-encrypted-backup.md` (backfilled). The other 6 backfilled SPs (SP10–SP16) have both spec and plan backfilled; SP17 has only the plan backfilled. The user said "12 backfilled plans for SP9-SP20" — so SP17 falls in that range — but the spec is original. This is an asymmetry in the doc-prep pass.
 12. **`audit_log` event-type vocabulary.** The SP14 spec §3.3 enumerates `claim.payer_rejected_acknowledged` as the audit event. The SP15 spec §3.4 enumerates `db.key_rotated`. The SP16 spec §3.5 enumerates `claim.rejected` (from 999 `_handle_999`) and `claim.payer_rejected` (from 277CA `_handle_277ca`). The completeness review (2026-06-20 §3.1 item 2) calls out `ActivityEvent` as "not tamper-evident" — but the SP11 audit log adds tamper-evidence only for events that *opt in* to `append_event`. The completeness review and the round-3 docs do not reconcile which `kind` strings go to `activity_events` (mutable) vs `audit_log` (hash-chained).
 13. **Live-tail reconnect backoff cap.** `REQUIREMENTS.md` §4 NFR-10 and FR-21: "backoff ladder `1s → 2s → 4s → 8s → 16s → 30s` capped". The `live-tail` spec §3.4 says the same ladder. The plan (`live-tail.md` Task 19) repeats it. **No contradiction here, but** the spec/plan/test all say "stalled at 30s silence" while the plan also says "the hook should NOT auto-reconnect on stall (user confirms)" — the FR-21 backoff ladder applies only to `reconnecting`, not `stalled`. A naive reader of FR-21 could think the stalled state auto-reconnects.
 14. **`store.add(rec, event_bus=…)` parameter.** The `production-readiness.md` plan Task 4 wires `store.add()` with `event_bus=request.app.state.event_bus`. The `claims-unique-constraint-and-409-ux.md` plan Task 1.3 calls `store.add(rec, event_bus=request.app.state.event_bus)` from the 837/835 endpoints. **But** the original `store.py:226` `InMemoryStore.add()` and the `CycloneStore.add()` impl do not have an `event_bus=` parameter — the call sites pass `event_bus=` to a function that does not accept it. This is *historical drift* (the InMemoryStore predates the EventBus in SP5) but the docs do not call out the refactor.
 15. **Migrations total count.** `REQUIREMENTS.md` §5.2 lists migrations `0001` through `0012` (12 total) but the §6.3 acceptance rows reference `0013_drop_claims_unique_constraint` (which is on the `claims-unique-fix` worktree, NOT on `main`). Engineers running `ls backend/src/cyclone/migrations/` on `main` see 12 files; engineers on the worktree see 13. The doc text is ambiguous about which branch it describes.
 16. **Test count target.** The historical `2026-06-20-completeness-review.md` §1 says **574 backend tests**. The `production-readiness.md` plan §"Test count targets" (Phase 2 final target) says **437 backend**. The `live-tail.md` plan §"Test count targets" says **437 backend + 144 frontend**. The user's question-statement says **964 tests**. **Four different numbers for "how many tests does Cyclone have".** The discrepancy is partly due to date (574 was measured in 2026-06-20; 437 was a target for SP5; 964 is current).
 17. **API router location for the rotation endpoint.** `2026-06-23-cyclone-sp15-key-rotation-design.md` §3.3 says the endpoint lives at `cyclone/api.py:2797-2928`. The actual endpoint lives at `backend/src/cyclone/api_routers/admin.py` (the `api_routers/` split happened after SP15 was written). The line range is stale.
 18. **Encrypted-at-rest posture.** `REQUIREMENTS.md` §4 NFR-5: "SQLite is encrypted via SQLCipher AES-256 when the macOS Keychain entry exists and `sqlcipher3` is installed; plain SQLite otherwise." `ARCHITECTURE.md` §10 Operational Story: "the SQLite file at `~/.local/share/cyclone/cyclone.db` is plaintext by default; SQLCipher optional." The two phrasings agree on substance but the operational story makes the "plaintext by default" stance more prominent than the requirements doc.
 19. **API endpoint for the MFT scheduler status.** The SP16 spec §4.1 says `GET /api/admin/scheduler/status` returns a `SchedulerStatus` JSON. The SP16 spec §3.3 says the `GET /api/health` endpoint also reports `snap.scheduler.running`. **Two endpoints expose scheduler state** with different shapes. The DoD does not say which is canonical.
 20. **Audit-event `actor` semantics.** SP14 spec §3.3 says `actor` defaults to `"operator"` and is operator-supplied via request body. SP15 spec §3.4 says the same. The SP23 candidate (`ubuntu-docker-deployment-design.md`) introduces RBAC and `actor` becomes a real identity from a JWT claim. The two phrasings agree on default behavior but differ on whether `actor` is free-form text (today) vs identity-validated (SP23 future). Engineers building an audit-evidence tool today must treat `actor` as untrusted free-form text.
 21. **`/api/clearhouse/submit` parameter shape.** SP13 spec §4 says no new endpoints, but references the SP9 endpoint `POST /api/clearhouse/submit`. The SP9 spec is the original spec (`2026-06-20-cyclone-multi-payer-npi-sftp-design.md`). The two docs disagree on the request shape: SP9 spec §4 has `body: { sftp_block_name, payload }`; SP13 spec §4 says SP9 endpoint body is "unchanged" but adds an `auth` dict to `SftpBlock` model. The exact request schema is documented in SP9 only; SP13 trusts it. Two readers building SP13 from spec-only could ship two different request bodies.
 22. **`processed_inbound_files` table ↔ scheduler hand-off.** The SP16 spec §3.5 says `_handle_999` and `_handle_277ca` write SP11 audit events. The plan for SP14 says `claim.payer_rejected_acknowledged` is an audit event. **Both audit events end up in the same `audit_log` table** but no doc names a "row kind namespace" — an operator querying `SELECT event_type, COUNT(*) FROM audit_log GROUP BY event_type` would need to enumerate every spec's event types to build a vocabulary.
 23. **Reconciliation failure semantics.** `REQUIREMENTS.md` §4 NFR-2 says reconciliation must be "fail-soft — a 999 parser crash does not lose the 835". The db-reconciliation spec §6.6 says the same. The completeness review §4 item 4 says "ActivityEvent is mutable". **Both can be true**, but the reconciliation "fail-soft" event goes to `activity_events` (mutable) and the SP16 "scheduler per-file try/except" event goes to `processed_inbound_files.error_message` (also not in `audit_log`). An auditor searching the hash-chained log for a reconciliation failure will find nothing for SP5-era crashes.
 24. **Store ownership of `parse_inbound_filename`.** The SP16 spec §3.5 says `_handle_999` etc. use `cyclone.edi.filenames.parse_inbound_filename` (a separate module under `cyclone/edi/filenames.py`). The completeness review (pre-SP16) doesn't mention this module. The SP16 spec was backfilled; the upstream SP9 spec for `SftpClient` does not mention `edi/filenames.py` either. The module exists in the codebase (`backend/src/cyclone/edi/filenames.py`) and is covered by `test_filenames.py` — but no spec describes *why* it lives in `edi/` instead of `parsers/`.
 25. **`claim.rejected` audit event idempotency.** SP16 spec §3.5 says `_handle_999` writes one `claim.rejected` audit event per matched claim. The SP6 workflow plan (`workflow-automation.md` Task 3) says `apply_999_rejections` is idempotent on already-rejected claims. **The interaction is: a 999 file applied twice (e.g. a retry) writes 0 new audit events on the second call (because `claim.state == REJECTED` short-circuits in `apply_999_rejections`).** The SP16 spec does not say "scheduler retries are idempotent on the audit chain" — only on the parser. A future scheduler retry-aware design might emit a `claim.rejected_reapplied` audit event, but no doc says so.
 ---
 ## 8. Forks (highest-priority first)
 These are the items where two competent engineers reading only the docs would plausibly build different systems.
 **F1 (P0). Tail endpoint URL.** FR-20 says `/api/{resource}/stream`; ARCHITECTURE §5.4 says `/api/tail?since=…`. Two URLs, two shapes, two different filter mechanisms. The codebase matches FR-20. **An engineer reading only ARCHITECTURE.md would build a single-endpoint `/api/tail?since=…` that does not exist.**
 **F2 (P0). Claim lifecycle state names.** REQUIREMENTS says 7 states (no `REJECTED`, has `received`); ARCHITECTURE says 7 states (with `accepted`, `appealed`, `rejected`, `payer_rejected`); code has 8 states (`SUBMITTED, RECEIVED, REJECTED, PAID, PARTIAL, DENIED, RECONCILED, REVERSED`); `ARCHITECTURE` adds `payer_rejected` as a state but the code does not. **An engineer building from REQUIREMENTS would ship a 7-state enum without `REJECTED` and break the SP6 workflow-automation `apply_999_rejections` path; an engineer building from ARCHITECTURE would ship a 7-state enum with `appealed` and `payer_rejected` and break the codebase.**
 **F3 (P0). Heartbeat interval.** 5s vs 15s. The code is 15s. An engineer deploying based on ARCHITECTURE §5.4 would set `CYCLONE_TAIL_HEARTBEAT_S=5` (or not set it and expect 5s) and double the bandwidth on the live-tail stream. An operator monitoring for "stalled" would flip state 5× as often.
 **F4 (P0). 409 collision response shape.** The SP22 `parse-decide-workflow-design.md` describes the 409 body for a CLM01 collision as `{parse_result, collisions: [{colliding_claim_ids, existing_batch_id}]}` — a richer shape that lets the UI surface "you have N existing batches that already hold this CLM01". The `claims-unique-constraint-and-409-ux.md` plan + spec describe the 409 body as `{error, detail, batch_id, existing_batch_id}` — a simpler shape that only carries the first matching batch. **The two specs describe different 409 contracts.** A frontend engineer building from SP22 will render a richer panel; one building from the claims-unique-constraint plan will render a simpler panel.
 **F5 (P1). `?ack=true` response shape on parse-837.** REQUIREMENTS §3.1 FR-9 says `?ack=true` "auto-generates a 999 acknowledgement". The `edi-features.md` plan Task 15 says "persist `Ack` row, attach to response body" — but the response shape is described as "the 999 is attached inline". The live-tail spec does not re-acknowledge. **Three different response shapes are plausible: (a) `{claims, summary, ack: {ack_id, body}}` with the 999 inline, (b) `{claims, summary, ack_id}` requiring a follow-up GET, (c) `{claims, summary, ack_999_x12: "ISA*..."}` with raw text. The plan's test (`test_api_parse_persists.py` ack=true happy path) checks the response, but no doc publishes the canonical shape.**
 **F6 (P1). `payer_rejected` lane ↔ `rejected` lane ordering.** SP14 spec §1 says the 5 lanes are ordered "envelope problems → payer problems → recon opportunities → claims in flight → done today". SP14 spec §3.7 code shows the order `rejected, payer_rejected, candidates, unmatched, done_today`. The SPEC.md says the same. The summary tile grid is `grid-cols-2 sm:grid-cols-3 lg:grid-cols-5`. **No conflict in the docs, but** if a future engineer "tidies" the lane order to alphabetical, the "Need eyes" counter (which sums `rejected + payer_rejected + candidates + unmatched` per SP14 spec §3.8) would still work; the visual hierarchy would change.
 **F7 (P1). `ActivityEvent` vs `audit_log` event namespace.** The codebase has two parallel event tables. The SP11 spec says `audit_log` is for HIPAA-relevant events (`claim.rejected`, `claim.payer_rejected_acknowledged`, `db.key_rotated`). The pre-SP11 design (still in `store.py`) writes `activity_events` for state transitions (`claim_submitted`, `manual_match`, `manual_unmatch`, `reconcile`, etc.). **No doc publishes a complete list of which event types go to which table.** A future engineer adding a new event (e.g. `claim.appealed`) would have to choose which table to use with no explicit guidance. *Note: SP23 candidate mentions "appeals workflow" without specifying the table.*
 **F8 (P1). `store.add(rec, event_bus=…)` signature.** The live-tail plan (SP5) and the unique-constraint plan (SP22) both call `store.add(rec, event_bus=request.app.state.event_bus)`. The pre-SP5 `InMemoryStore.add()` does not accept `event_bus=`; the post-SP5 `CycloneStore.add()` signature is unclear from the docs. **A new engineer refactoring `store.py` (which SP21 plans to do) could break both call sites.** The plan-level dependency on SP5's `event_bus` is implicit in 7+ places; the SP21 spec does not list this as a constraint.
 **F9 (P1). `api.py` → `api_routers/` split.** The codebase has `api_routers/{acks,admin,health,ta1_acks}.py`. The specs all reference `cyclone.api:app`. **An engineer building from the docs would add new endpoints to `api.py`; an engineer reading the codebase would add to `api_routers/`.** The split is undocumented in the top-level docs.
 **F10 (P1). Live-tail stream filter.** FR-20 says the stream is per-resource. The `live-tail.md` plan Task 11 shows the endpoint signature accepting `status, provider_npi, payer, date_from, date_to, sort, order, limit` — i.e. the stream is a *filterable* snapshot+subscription, not a firehose. **Two engineers reading the docs would build: (a) firehose stream that the frontend filters (matches the FR-20 phrasing); (b) filtered stream matching `listClaims` parameters (matches the plan Task 11 signature).** The actual code matches (b).
 **F11 (P2). `processed_inbound_files` row identity.** SP16 spec §2.2 says the unique index is `(sftp_block_name, name)`. The plan test `test_persist_835_creates_one_service_line_payment_per_svc_composite` builds a `SftpBlock` and a `ClaimPayment` with one `name`. **If a single inbound file has two `999` envelopes concatenated (the HCPF pattern is one file per inbound type), the scheduler classifies via `parse_inbound_filename` and stores one `processed_inbound_files` row per inbound type — but the spec does not say whether the same inbound MFT path could have two acks for two different control numbers.** Edge case; probably out of scope; but undocumented.
 **F12 (P2). `audit_log` clock source.** SP11 spec §3 says `created_at` is "the wall-clock at the time of `append_event`". The SP16 spec says the scheduler "stagger by 1s on startup so a multi-operator restart doesn't hammer the MFT server". If a 999 arrives at wall-clock `T`, the `claim.rejected` audit event has `created_at = T`. If the operator's wall-clock drifts 2s from the server's, the chain still works (it's hash-chained by SHA-256, not timestamp-ordered). **No doc says what "created_at" means — wall-clock at the operator host, or monotonic at the scheduler.** This matters for HIPAA §164.312(b) audit retention (6 years) where operators may need to prove the audit chain was written *before* the corresponding DB write.
 **F13 (P2). `claim.id` source.** SP10 spec §2 says `claim.id` is the X12 CLM01. SP14 spec §2 says the lane filter is on `payer_rejected_at` (not `claim.id`). The uniqueness-constraint spec (SP22) says `claim.id = CLM01` AND that 837P allows many `CLM*` segments per 2000B subscriber loop. **If a 837P file has two CLM01 collisions (e.g. two CLM01="CLM-A" segments in different 2000B loops), the `PK on claims.id` raises IntegrityError on the second insert.** SP22 migration 0013 drops the inline UNIQUE on `(batch_id, patient_control_number)` to allow this, but the PK remains on `claims.id`. **Two CLM01="CLM-A" segments still trip the PK.** The 409 handler returns `existing_batch_id` only if the prior batch holds the colliding CLM01 — but if the second collision is *within the same file*, the second insert raises before any prior batch is consulted. The 409 body in this case is `{error, detail, batch_id}` *without* `existing_batch_id`. SP22 spec does not document this edge case.
 **F14 (P2). SFTP host-key policy.** SP13 spec §3.2 uses `AutoAddPolicy()` (trust-on-first-use). The plan does not change this. The spec §7 "Open questions" lists `SftpBlock.strict_host_key_check: bool` as a future hardening. **An engineer hardening security to `RejectPolicy` today would break first-connect for any new operator.** No doc says "do not change this without a migration path".
 **F15 (P2). `processed_inbound_files` status `pending`.** SP16 spec §2.3 says `pending` is "reserved for the retry-on-next-tick semantics" but is "currently unused in shipping code". The plan does not add a test for the `pending` status. **A future engineer implementing retry semantics would need to know the schema already supports `pending`**; the spec calls this out but the plan does not.
 **F16 (P2). Scheduler first-tick stagger.** SP16 spec §3.1.2 says `_run` staggers the first tick by 1s on startup. The plan test does not assert the stagger (only that the scheduler "starts"). **A future engineer removing the `asyncio.sleep(1)` for "simplicity" would re-introduce the thundering-herd problem without test coverage catching it.**
 **F17 (P3). `_handle_277ca` vs `_handle_999` line numbers.** SP16 spec §3.1.1 says both handlers emit `claim.rejected` / `claim.payer_rejected` audit events. The `_handle_277ca` path is also called for filename `277` (not just `277CA`) — same parser, different filename pattern. **A future engineer renaming the handler would have to update both the spec and the plan.**
 **F18 (P3). `serialize_837_for_resubmit` parameter shape.** SP8 plan Task 5 says `serialize_837_for_resubmit(claim, interchange_index=42)` assigns `f"{interchange_index:09d}"`. The spec says the same. But the spec §3.1 originally proposed "hybrid" approach; the plan Task 0 amends to "Approach A full rebuild". **An engineer reading only the spec would write a hybrid serializer; one reading the plan would write a full rebuild.**
 **F19 (P3). SP22 parse-decide spec vs plan.** The SP22 parse-decide spec §3.2 says the 409 endpoint returns `parse_result` and `collisions` arrays. The SP22 plan does not exist (only the claims-unique-constraint plan exists for SP22). **Engineers building from the spec alone have no test plan.** The spec mentions a "TBD: 409 panel UX" in §6.
 **F20 (P3). Inbox lane ordering by `state_changed_at`.** SP6 workflow-automation plan Task 6 `compute_lanes` uses `Claim.state_changed_at >= cutoff` for the `done_today` lane (cutoff = 24h ago). The migration `0004_rejections_and_state_history.sql` adds `state_changed_at` and the index `ix_claims_state_changed_at`. **The migration adds the column WITHOUT a default value** — so existing claims (from migrations 0001–0003) have `state_changed_at = NULL`. **They never appear in `done_today`.** An operator who upgrades from pre-SP6 to SP6 would see their historical claims never land in `done_today`. SP6 spec does not say "backfill `state_changed_at` on existing claims"; the plan does not test for this.
 **F21 (P3). The SP10 277CA path does not extend the state machine.** A claim with a payer rejection stays in its prior state (`paid`, `denied`, `partial`, etc.) and gains the `payer_rejected_at` timestamp. This is consistent with SP10 spec §2.3 ("we explicitly do not clear `payer_rejected_at` on acknowledge") and SP14 spec §2.3, but the architecture doc's casual phrasing ("states: ... payer_rejected") suggests otherwise. **An engineer building the data model from the architecture doc will add a `payer_rejected` ClaimState value that breaks the lane query.**

 ## 9. Untested artifacts
 The following are claims in the docs that are not (verifiably) backed by tests in `backend/tests/` or `src/**/*.test.ts*`. I name the test file that *should* cover each.
 **U1.** `REQUIREMENTS.md` §4 NFR-2: "every route has a happy-path test and at least one failure-path test". **This NFR is a meta-claim about test discipline.** No meta-test asserts NFR-2 (e.g., a `pytest --collect-only | jq '.[] | select(.failure_path == false)'` would fail). The convention is followed in some places (e.g. `test_api_rotate_key.py` has happy + 409 + 503 paths; `test_payer_rejected_acknowledge.py` has 6 tests covering happy / idempotent / missing / not-rejected / empty / audit) but not enforced.
 **U2.** `REQUIREMENTS.md` §4 NFR-10: "backoff ladder 1s → 2s → 4s → 8s → 16s → 30s capped". The `live-tail.md` plan Task 19 enumerates 6 status states (`connecting / live / reconnecting / stalled / error / closed`) but the test plan (`test_useTailStream.test.ts`) covers only 4 (connecting→live, error, abort/closed, reconnecting→connecting→live). **The backoff ladder cap (30s) is not asserted.** A future engineer could ship backoff that climbs past 30s without test failure.
 **U3.** `REQUIREMENTS.md` §4 NFR-9: "thread-affinity under FastAPI: every SQLCipher connection opens on the calling thread via `poolclass=NullPool`". `db_crypto.py` is the only module that wires `NullPool`. **No test in `test_db_crypto.py` asserts `poolclass == NullPool` is set on the SQLCipher branch.** An engineer refactoring `_make_engine` to switch to `QueuePool` (SQLAlchemy default) would break thread-affinity without test coverage catching it.
 **U4.** SP15 spec §3.3 says the rotation endpoint has status codes `200, 400, 409, 503`. `test_api_rotate_key.py` covers happy + 409 + 503. **The 400 ("encryption not enabled") path is not in the test file.** An engineer removing the `is_encryption_enabled()` check would not break tests.
 **U5.** SP14 spec §3.3 says `POST /api/inbox/payer-rejected/acknowledge` returns 400 when `claim_ids` is "missing, empty, or contains non-string elements". `test_payer_rejected_acknowledge.py` (per SP14 spec §8) has 6 tests: happy path; idempotent re-ack; skip non-payer-rejected; missing-id count; **400 on empty list**; audit event written + chain intact. **The 400-on-non-string-elements path is not tested.**
 **U6.** SP16 spec §3.5 says `_handle_ta1` "writes no audit event — TA1s are envelope-level interchange acks and are not HIPAA-relevant". **No test asserts that `_handle_ta1` writes zero audit rows.** A future engineer adding a "ta1.received" audit event would not break tests.
 **U7.** SP16 spec §7.4 says "list_inbound() runs on a thread via asyncio.to_thread so the event loop stays responsive". **No test asserts that `SftpClient.list_inbound()` does not block the event loop** (e.g. a `test_list_inbound_runs_off_loop` would need to schedule a CPU-bound task on the loop and verify it ran concurrently with `list_inbound`).
 **U8.** SP12 spec §7 says "Plain-SQLite fallback remains silent. `is_encryption_enabled()` returns False when `sqlcipher3` isn't installed or the Keychain entry is missing." `test_db_crypto.py` covers the case where encryption IS enabled. **The "sqlcipher3 not installed" branch is not tested** (the test environment always has `sqlcipher3` because the dev deps install it).
 **U9.** SP13 spec §3.2 says `_connect` raises `RuntimeError("SftpBlock.auth must contain either 'password_keychain_account' or 'key_file'")` when both keys are absent. **No test in `test_sftp_paramiko.py` covers this exact error message** (the plan Task 19 enumerates 5 tests: connect happy, key-file happy, missing-password RuntimeError, network error, AutoAddPolicy — but the "both auth keys absent" case is not explicit).
 **U10.** SP11 spec §3.4 says `append_event` re-raises if the hash computation fails (which is impossible in practice because SHA-256 doesn't fail, but the doc claims the function is "fail-fast"). **No test asserts the fail-fast behavior under any failure mode.**
 **U11.** SP14 spec §3.8 says "The row payload already carries `payer_rejected_acknowledged_at` / `_actor` (always null on the current lane)". `test_lane_filter_acknowledged.py` covers "row payload carries the ack fields (forward-compat)". **The test name says "forward-compat" but the test does not assert the fields are null on the lane — only that they exist on the row.**
 **U12.** SP18 spec (`structured-logging`) is not yet a backfilled spec; the implementation lives at `backend/src/cyclone/logging_config.py`. `test_logging_formatter.py`, `test_logging_scrubber.py`, `test_logging_setup.py` exist. **No spec describes the `PiiScrubber` regex list** (which PHI patterns it redacts); the spec is a backfill gap.
 **U13.** `REQUIREMENTS.md` §6.1 traceability FR-35 says "5-lane Inbox" was satisfied by SP14; the §6.3 acceptance row for SP14 says "All 5 lanes render in `/inbox`; bulk acknowledge action drops payer-rejected claims without erasing the original rejection". **`test_lane_filter_acknowledged.py` covers the lane filter and `test_payer_rejected_acknowledge.py` covers the ack endpoint. There is no integration test that renders all 5 lanes simultaneously** (each lane's UI rendering is in `BulkBar.test.tsx` per the SP14 spec §8 table, but the page-level test for `Inbox.tsx` with 5 populated lanes is not enumerated).
 **U14.** SP16 spec §3.5 says `_handle_ta1` calls `cyclone.store.store.add_ta1_ack`. **The `test_api_ta1.py` exists and the `test_scheduler.py` has a TA1 routing test, but no test asserts that `_handle_ta1` correctly persists a TA1 ack row end-to-end through the scheduler (vs through the manual `/api/parse-ta1` endpoint).**
 **U15.** `REQUIREMENTS.md` §6.1 FR-15 says "Per-service-line adjustment audit: 837 SV1 ↔ 835 SVC strict match, line reconciliation tab". `test_line_reconciliation.py` covers the pure-function `match_service_lines` (per SP7 plan Task 7). **`test_reconcile_line_level.py` covers the integration with `reconcile.run()`. But there is no frontend test for the "Line Reconciliation tab" UI** (the spec is for backend data only; the tab is described but the SP7 spec is silent on the frontend tab layout; the frontend is presumably covered by `Reconciliation.tsx.test.tsx` but SP7 doesn't enumerate it).
 **U16.** `REQUIREMENTS.md` §6.1 FR-33 says "Rich health payload on `GET /api/health` with last-batch-timestamp, parser state, pubsub health, scheduler state". `test_security.py` exists for the `get_health_snapshot()` function. **No test asserts that `last_batch_timestamp` is populated when a batch has been parsed** (the field is added by SP19; the spec expansion is not enumerated in any plan's test plan).
 **U17.** `REQUIREMENTS.md` §6.1 FR-26 says "paramiko-backed SFTP submit, credentials via `keyring`". `test_sftp_paramiko.py` covers the connect / write / list / read happy paths. **The test does not assert that an empty password raises `RuntimeError("SFTP: Keychain entry ... missing or stub")`** — it only asserts the runtime error type, not the message. An engineer changing the error message would not break the test.
 **U18.** SP11 spec §7 says the audit chain verifier returns `ok: true, checked: N+1` where N is the number of rows. **`test_audit_log.py` exists but the test for `verify_chain` with a tampered row is not enumerated in any plan's test inventory.** A future engineer changing `_hash_row` to use a different canonicalization (e.g. including the row id) would silently break the chain with no test catching it.
 ---
 ## 10. Escalations (`ESCALATE:` prefix)
 These are non-obvious product decisions in the docs that an engineer would benefit from confirming with the user.
 **ESCALATE: SP23 — Ubuntu Docker + RBAC.** `docs/superpowers/specs/2026-06-22-cyclone-ubuntu-docker-deployment-design.md` is marked "Draft / candidate". It introduces (a) a Docker image (`Dockerfile` + `docker-compose.yml`), (b) 3-role RBAC (admin / operator / viewer) backed by `cyclone.auth`, (c) per-role scoping on every endpoint, (d) JWT-based session tokens. **This is a fundamental posture change** — Cyclone today binds `127.0.0.1` with no auth. The spec does not say whether the existing single-operator flow is preserved as a "no-auth" mode under Docker (with RBAC opt-in), or whether RBAC is mandatory. The completeness review (2026-06-20) and the round-3 docs both treat SP23 as optional, but the spec title (`ubuntu-docker-deployment`) suggests it is the canonical deployment posture. **Confirm: is SP23 in scope for the next release, or is it parked? If parked, what is the deployment story?**
 **ESCALATE: SFTP `AutoAddPolicy` vs `RejectPolicy`.** SP13 spec §3.2 says `AutoAddPolicy()` is the v1 trade-off; §7 "Open questions" lists `strict_host_key_check: bool` as future hardening. **In a HIPAA-regulated workflow, trust-on-first-use is a known MITM-attack vector.** The spec acknowledges this and proposes a `known_hosts` switch as future work. **Confirm: is `AutoAddPolicy` acceptable for the v1 release, or should SP13 ship with `RejectPolicy` + a bundled `known_hosts` file? The Gainwell MFT host key would need to be obtained and pinned.**
 **ESCALATE: `audit_log` retention is "≥ 6 years" (HIPAA §164.316(b)(2)) but the docs do not say how.** SP11 spec §7 says "pinned audit-log retention for rotation events: `db.key_rotated` rows live in the SP11 chain; SP11 already commits to long-term retention per HIPAA §164.316(b)(2). No additional retention config is needed." But the migration `0009_audit_log.sql` does NOT add a retention config (no `created_at + INDEX`, no `prune_event` cron). The 6-year retention is implicitly guaranteed by (a) the operator never pruning the table, and (b) the encrypted backup SP17 covering the `audit_log` rows. **Confirm: is "operator never prunes" the retention policy, or should the spec describe an automated retention policy (e.g. a `prune_audit_log` cron at 6 years + 1 day)?**
 **ESCALATE: The 5-lane Inbox vs 4-lane state machine.** The SP10 spec says `payer_rejected_at` is a column on `claims` (not a state). The SP14 spec says the 5th lane is computed by filtering. **The operator's mental model is: "I have a `rejected` claim or a `payer_rejected` claim." But the code says: a claim is in one state (`paid`, `denied`, `partial`, etc.) AND has a `payer_rejected_at` timestamp (or doesn't).** The 5-lane UI surfaces 5 working categories, but the underlying state machine has 8 states + 4 timestamp columns. **Confirm: should the operator see `state` AND `payer_rejected_at` as separate concerns, or should the data model be unified into a 9-state enum where `payer_rejected` is a terminal state (like `reversed`)?**
 **ESCALATE: SP21 store split is in-flight on `refactor/store-split`.** The spec is dated 2026-06-21; the current `backend/src/cyclone/store.py` is the monolithic version. The DR plan ("3 reviewers, 5-day merge window") is in the spec §10 but no plan exists for SP21. **Confirm: is the store split a release-blocker, or can it ship after the audit chain + MFT scheduler are stable? An engineer building SP22+ on top of the monolithic store would have to migrate to the split store later.**
 **ESCALATE: SP22 parse-decide spec describes a 409 shape that contradicts the unique-constraint spec.** The 409 body in SP22 is `{parse_result, collisions: [{colliding_claim_ids, existing_batch_id}]}`; in the unique-constraint spec it is `{error, detail, batch_id, existing_batch_id}`. **Confirm: which is canonical? If the richer shape is canonical, the claims-unique-constraint spec needs a follow-up to update the 409 body and the frontend `Upload.tsx` error panel.**
 **ESCALATE: Reconciliation failure events go to `activity_events` (mutable), not `audit_log` (hash-chained).** The completeness review (2026-06-20 §3.1 item 2) flagged `activity_events` as not tamper-evident. The round-3 docs (SP11) added `audit_log` but did not migrate the reconciliation failure events. **Confirm: should `activity_events` rows for `kind='reconcile_failure'` be migrated to `audit_log`? Or is the operator's "reconciliation is fail-soft" claim enough, and the audit-evidence requirement only applies to HIPAA-relevant events (parse, reject, payer-rejected, key rotation)?**
 **ESCALATE: `?ack=true` on parse-837 returns the 999 inline vs in a separate field.** REQUIREMENTS FR-9 says the 999 is auto-generated; the edi-features plan Task 15 says the ack is "attached to the response body"; the live-tail spec does not re-acknowledge. **Confirm: should the 999 be returned inline as `ack.x12_text` (raw X12 string), as `ack.body` (parsed object), or as a `ack_id` requiring a follow-up `GET /api/acks/{id}`? The `serialize_999` module exists in `parsers/`, so inline raw text is straightforward.**
 **ESCALATE: 5-lane Inbox claim ownership.** The lane filter for `payer_rejected` is on the `claims` table. The 999-rejected lane (`rejected`) is also on the `claims` table. The `unmatched` lane is on `claims` with no matched remit. **But what about a claim that is both `rejected` (by 999) and `payer_rejected` (by 277CA)?** The SP14 spec §3.2 SQL filter puts it in the `rejected` lane (because `state == REJECTED` takes precedence over the `payer_rejected_at` check). The spec does not say this explicitly. **Confirm: should a 999-rejected + 277CA-payer-rejected claim appear in both lanes (UI splits), or in the `rejected` lane only (operator workflow assumes rejection order)?**
 **ESCALATE: SP15 key rotation endpoint has actor="operator" hard-coded default.** The actor is request-body-supplied; the SP15 spec §7 says "for v1 single-operator, `'operator'` is honest". The SP23 candidate introduces RBAC where actor becomes a real identity. **Confirm: should the v1 single-operator posture be honored with `actor="operator"`, or should the request require an actor parameter (rejecting "operator" as ambiguous)?**
 **ESCALATE: `processed_inbound_files` is operational metadata, not in the HIPAA audit chain (SP16 spec §2.4).** The scheduler's per-file errors are recorded in `processed_inbound_files.error_message` (mutable, not in `audit_log`). **Confirm: should scheduler errors (e.g. `parse_999` raising `Exception` on a malformed inbound) ALSO be logged in `audit_log` as `scheduler.parse_error`? An auditor investigating a 999 parse failure today would find nothing in the hash-chained log.**
 **ESCALATE: Backend test count is variously reported as 574 (completeness review 2026-06-20), 437 (SP5 plan target), and 964 (current — per user).** The codebase has 94 test files in `backend/tests/`; individual test functions are not enumerated in this review (running pytest was not permitted). **The traceability matrix in REQUIREMENTS.md §6.1 cites one test file per FR — but a single FR may have 5+ tests in that file.** Confirm: is the FR-coverage criterion "≥1 test file" or "≥1 test function"?
 ---
 ## 11. Confidence
 **Overall confidence in the doc set: medium-low.**
 The doc set has high production quality: 27 specs + 27 plans + 2 top-level docs, all version-controlled and consistent in style. The TDD discipline in the plans (write failing test, run, implement, run, commit) is exemplary. The layering (requirements → architecture → spec → plan → tests) is the right structure. The completeness review (2026-06-20) and the round-3 doc-prep pass added the missing SP10–SP16 specs/plans, which closes a major gap. **But the doc set has accumulated at least 25 specific contradictions, ambiguous forks, and stale numbers** between the two top-level docs and across the spec/plan set. The contradictions are concentrated in the most consequential areas: the live-tail HTTP surface, the claim-state machine, and the LOC/version counters used in the verification matrix. The 7-state claim lifecycle is wrong in 5 places; the codebase has an 8-state enum (verified at `backend/src/cyclone/db.py:180-188`). The tail endpoint URL is `/api/{resource}/stream` per FR-20 + the live-tail spec, but `/api/tail?since=…` per ARCHITECTURE.md §5.4 — two competent engineers reading only the docs could ship two incompatible APIs. The 5 s heartbeat in ARCHITECTURE is contradicted by REQUIREMENTS and the code (which both use 15s via `CYCLONE_TAIL_HEARTBEAT_S`). The 409 collision response shape has two different shapes in two specs (SP22 vs unique-constraint). The `api_routers/` partial split is invisible to the top-level docs. SP21/SP22/SP23 are in-flight or candidate but not marked as such in the top-level docs. The audit_log vs activity_events event-namespace ambiguity is not documented. **The doc set is shippable as a historical record of work done, but is NOT safe as the *only* source of truth for a future engineer building on top of it.** For each of the 21 forks in §8, two competent engineers could ship different systems. For each of the 18 untested artifacts in §9, an engineer refactoring could silently break documented behavior without test coverage catching it. For each of the 12 escalations in §10, a product decision needs user input before the next release.
 **Recommendation**: do not ship the doc set as-is. Fix the contradictions in §7 #1–7 (the LOC counts, the heartbeat interval, the tail endpoint URL, the 7-state lifecycle, the payer_rejected-as-state) before the next reviewer pass. Resolve the 409 shape fork in §8 #F4 (SP22 vs unique-constraint) before any 837P file with internal CLM01 collisions can ship. Document the audit_log vs activity_events split (§8 #F7) before the SP21 store split lands. Add tests for the 18 untested artifacts in §9. Confirm the 12 escalations in §10 with the user before the next release cycle.

 # Cyclone doc-prep review — Reviewer B (code-first lens)
 ## 1. Reviewer identity + lens
 I am **Reviewer B**. I used a **code-first lens** for the Cyclone doc-prep pass:
 the bulk of my exploration was in the source tree — `backend/src/cyclone/`
 (`api.py`, `api_helpers.py`, `api_routers/`, `db.py`, `store.py`, `audit_log.py`,
 `security.py`, `db_crypto.py`, `backup_service.py`, `reconcile.py`,
 `inbox_lanes.py`, `scoring.py`, `inbox_state.py`, `inbox_state_277ca.py`,
 `scheduler.py`, `parsers/`, `migrations/0001-0012`) and
 `src/{routes,store,lib,hooks,components}/` (notably the live-tail client
 `src/lib/tail-stream.ts` and the React hook `src/hooks/useTailStream.ts`).
 I then read the top-of-funnel docs in the intended order:
 `docs/README.md` → `docs/REQUIREMENTS.md` → `docs/ARCHITECTURE.md`. From
 there I cross-referenced the 20 spec files and 27 plan files in
 `docs/superpowers/specs/` and `docs/superpowers/plans/`. **I did not read
 Reviewer A's `docs/reviews/2026-06-23-cyclone-docset-review-A.md` before
 writing this review** so my findings are independent of any
 docs-first anchoring. I have flagged every claim with a `file:line`
 citation, and where the code disagrees with the doc, the code wins —
 the doc needs fixing.
 ## 2. Executive summary
 The Cyclone doc set is in **moderate health with a small number of
 high-severity contradictions** that would mislead any engineer reading
 docs first. The implementation is unusually self-consistent and matches
 the SP-spec lineage, but the two top-level docs (`REQUIREMENTS.md`,
 `ARCHITECTURE.md`) and several inline code docstrings have drifted from
 the SP-spec + code truth. The top three issues are:
 1. **The audit-chain hash recipe is wrong in three places** (the
   `AuditLog` docstring in `db.py:649-650`, the `audit_log.py:6-7`
   module docstring, and `ARCHITECTURE.md` §4.6) and only the SP11 spec
   (`docs/superpowers/specs/2026-06-23-cyclone-sp11-hash-chained-audit-design.md:104-114`)
   plus the actual `_hash_row` function at
   `backend/src/cyclone/audit_log.py:80-89` agree. This is a C-1
   severity finding because the verifier and any future auditor will
   compute different hashes depending on which doc they read first.
 2. **`ARCHITECTURE.md` §6.3 lists the wrong claim state set** (eight
   values, but the wrong eight — it has `accepted`, `appealed`, and
   `payer_rejected`, none of which exist in code). The actual `ClaimState`
   enum (`db.py:180-188`) is `submitted, received, rejected, paid, partial,
   denied, reconciled, reversed`. The `RECONCILED` state is defined and
   is treated as terminal by `apply_payment` (`reconcile.py:163-178`) but
   is never actually set by any code path, which is a separate
   fork-shaped finding (F-1).
 3. **The API surface in `ARCHITECTURE.md` §8.1 is materially wrong** for
   live tail, the Inbox 5-lane, and the backup restore flow. Live tail
   is documented as `GET /api/tail?since=…` (ARCH §5.4 / §8.2) and as
   `GET /api/{claims,remittances,activity}/stream` in REQUIREMENTS FR-20
   — the code is the latter (`api.py` 3,548 LOC; verified at multiple
   routes). Inbox is listed as `/api/inbox` in ARCH §8.1 but the real
   surface is `/api/inbox/lanes`, `/api/inbox/payer-rejected/acknowledge`,
   etc. Backup restore is a one-step URL in ARCH §8.1 but the
   `backup_service.py` is a two-step `restore_initiate` / `restore_confirm`
   (matches FR-30). The two-step shape is what the code ships.
 Below the top three, the doc set has many smaller drifts — the live-tail
 heartbeat cadence is documented as 5s in ARCH §5.4 (code is 15s default;
 NFR-10 is silent on default but the SP5 spec is 15s), the `clearhouse`
 ORM is a singleton (singular table) but ARCH §6.2 draws the ERD as
 `clearhouses` (plural), the migration 0004 is misdescribed in ARCH §6.1
 as adding a new table when it actually adds four columns to `claims`,
 and the spec-vs-code disagreement over the `Match.claim_id` UNIQUE
 constraint (SP2 §6.5 says UNIQUE; code explicitly doesn't enforce it so
 reversals can add a second row).
 There are also **two product forks that are blocking-or-near-blocking**
 that the docs do not decide: the SP23 Ubuntu/Docker/auth/RBAC/LAN-bind
 direction (spec at `2026-06-22-cyclone-ubuntu-docker-deployment-design.md`
 exists, no plan exists; REQUIREMENTS R-1, R-3, R-24 raise but do not
 close this), and the `RECONCILED` state being declared terminal but
 never assigned. Neither has a test, plan, or design decision recorded.
 ## 3. Reviewer questions
 ### Q1: Are the components described consistently across REQUIREMENTS, ARCHITECTURE, specs, and plans?
 **Verdict: NO — multiple component-name and component-shape mismatches.**
 Reasoning:
 - The **`Live tail` component** is described three different ways:
  REQUIREMENTS FR-20 says `/api/{claims,remittances,activity}/stream`
  (NDJSON); ARCH §5.4 and §8.2 say `GET /api/tail?since=<last_event_id>`;
  SP5 spec says per-resource `…/stream` and the NDJSON line shape is
  `{"kind": "item"|"snapshot_end"|"heartbeat"|"item_dropped"|"error", …}`
  (matches the React client's `src/lib/tail-stream.ts` `TailEvent`
  type). The code is the SP5 spec; REQUIREMENTS matches the code; ARCH
  does not.
 - The **`Inbox` component** is described as `/api/inbox` in ARCH §8.1
  but as a 5-lane surface in REQUIREMENTS FR-12 / FR-13 / FR-14 and in
  the SP14 spec, and the code (`api.py`; `inbox_lanes.py` at lines
  1-280) implements `/api/inbox/lanes` plus
  `/api/inbox/payer-rejected/acknowledge`, plus `GET /api/inbox/999` and
  `GET /api/inbox/277ca` style endpoints. ARCH §8.1 is missing the 5-lane
  detail.
 - The **`Backup restore` component** is described as a single URL in
  ARCH §8.1 (`/api/admin/backup/{id}/restore?confirm=true`) but as a
  two-step `restore_initiate` / `restore_confirm` in REQUIREMENTS FR-30
  and in the `backup_service.py:851` LOC file. The code is the
  two-step shape.
 - The **`Database key rotation` component** is described in ARCH §8.1
  only by the endpoint `/api/admin/db/rotate-key`, but the SP15 spec
  defines a four-step ordering (DB-first → Keychain-second →
  engine-rebuild → audit-last) and a specific `db.key_rotated` audit
  event payload `{old_fingerprint, new_fingerprint, table_count, reason}`.
  Neither the ordering nor the payload shape is in ARCH.
 ### Q2: Is the data model consistent (schema, enums, lifecycle, audit chain)?
 **Verdict: NO — five material data-model disagreements.**
 Reasoning:
 - **Claim state enum is wrong in ARCH §6.3 and partially wrong in
  REQUIREMENTS FR-6.** REQUIREMENTS FR-6 says "7-state" but lists 8
  (in different versions of the doc over time). ARCH §6.3 lists
  `submitted, accepted, paid, reversed, denied, appealed, rejected,
  payer_rejected`. The code (`db.py:180-188`) is `submitted, received,
  rejected, paid, partial, denied, reconciled, reversed`. Only five
  values match across all four (`submitted, paid, partial, denied,
  reversed`; note: ARCH does not have `partial` either, which is the
  most common auto-reconcile outcome). SP2 spec lists 7
  (`submitted, received, paid, partial, denied, reconciled, reversed`).
  The `rejected` state is set by 999 AK9 set-level R/E (per
  `inbox_state.py` lines 1-76 and migration 0004), not by any spec
  other than SP6. The `reconciled` state is dead code — see F-1.
 - **Audit chain hash recipe disagrees in 3 places** (see C-1 below).
 - **The `clearhouse` table is a singleton** in code (`db.py:824-838`
  `__tablename__ = "clearhouse"`, single row, with a `SingletonError`
  exception for inserts past row 1) but the ERD in ARCH §6.2 shows
  `clearhouses` plural. Migration 0011 (`0001-0012` index) also writes
  to `clearhouse` (singular).
 - **The `Claim(batch_id, patient_control_number)` UNIQUE constraint
  is missing in code** but is asserted in SP2 spec §6.2 line 166 and
  was the subject of migrations 0003 and 0013+0014 (the in-flight
  `claims-unique-fix` worktree). The `claims` table in migration 0001
  has no such UNIQUE; the `Claim` ORM (`db.py:310-319`) explicitly
  notes the absence. The SP2 spec is out of sync with the SP-13/14
  reality.
 - **The `Match.claim_id` UNIQUE constraint is missing in code** but is
  asserted in SP2 spec §6.5 line 207. Migration 0001 line 65-66
  (comment) and `db.py:505` (ORM comment) say reversals add a 2nd row
  to `matches`, so UNIQUE on `claim_id` would be wrong. The spec is
  wrong; the code is correct.
 ### Q3: Are the dependencies and external integrations (SQLCipher, SFTP, MFT, key rotation, audit) consistent and traceable?
 **Verdict: MOSTLY YES — SQLCipher + key rotation are well-traced, MFT file routing has one ambiguity.**
 Reasoning:
 - **SQLCipher + key rotation** is end-to-end traceable:
  `db_crypto.py:389` LOC defines `KEYCHAIN_ACCOUNT = "cyclone.db.key"`
  and `KEYCHAIN_ACCOUNT_PREVIOUS = "cyclone.db.key.previous"`, uses
  `NullPool` for thread affinity, exposes `RotateKeyResult` with
  `old_fingerprint` and `new_fingerprint` (matches SP15 spec),
  and `api.py:2797` exposes `POST /api/admin/db/rotate-key` (matches
  REQUIREMENTS FR-32 and the SP15 spec endpoint name). Migration 0012
  is the SQLCipher-key-on-disk path. The audit event `db.key_rotated`
  has the spec-mandated payload shape `{old_fingerprint, new_fingerprint,
  table_count, reason}` in `db_crypto.py`. **Consistent.**
 - **MFT file routing** has a small ambiguity: `scheduler.py:316-321`
  routes `ROUTED_FILE_TYPES = {"999", "835", "277", "277CA", "TA1"}` to
  the corresponding parsers. SP10 spec says HCPF sends a bare `277` (not
  `277CA`) but the scheduler accepts both. This is intentional (defense
  in depth) but the doc should say so.
 - **Audit chain** has a write/read asymmetry: the chain is computed on
  append by `append_event()` and verified by `verify_chain()`, but the
  *docstring recipe* is wrong (see C-1). Code wins.
 - **SFTP and MFT** are documented only by reference to `paramiko` (SFTP
  transport) in `pyproject.toml` and by the `MFT_SCHEDULE` config in
  `config/payers.yaml`. There's no spec or plan I could find that says
  what the MFT pickup cadence should be, what the retry policy is, or
  what the failure alert looks like. This is a coverage gap, not a
  contradiction.
 - **SSE / live tail transport** is described as "NDJSON pubsub" in
  REQUIREMENTS NFR-10 and "NDJSON via `EventBus`" in ARCH §5.4. The code
  is NDJSON via `tail_events()` in `api_helpers.py:225` reading from
  `EventBus`. Consistent.
 ### Q4: Is "definition of done" testable for every artifact?
 **Verdict: NO — at least 6 artifacts are undertested, and the test surface is uneven.**
 Reasoning:
 - **Audit chain verifier** has tests in `test_audit_log.py` (per
  the `verify_chain()` reference in REQUIREMENTS NFR-4) but the
  *docstring recipe* in `audit_log.py:6-7` and `db.py:649-650` does
  not match the implementation. The tests verify the implementation
  but the docstring is the wrong contract.
 - **Score breakdown** (40/25/20/15) has tests and is documented in
  REQUIREMENTS FR-15, `scoring.py:42-46`, and the SP13 spec.
  Testable.
 - **Backup passphrase-missing degraded mode** (backup service falls
  back to deriving from SQLCipher key with a WARNING when no
  Keychain passphrase is set) is implemented in `backup_service.py`
  but has no test asserting the WARNING is emitted; REQUIREMENTS
  NFR-6 only asserts that the passphrase is in Keychain. The
  degraded-mode code path is untested.
 - **5-lane Inbox** has tests but the lane-tally API contract is not
  documented anywhere; the code returns a JSON with `lane_counts`
  but no spec defines the exact shape.
 - **Live tail stall detection** (30s stall timeout in
  `src/lib/tail-stream.ts` and `src/hooks/useTailStream.ts`) is
  not asserted in any backend test — only the client side knows
  about the stall; the server keeps streaming. Not testable from
  the spec alone.
 - **277CA monotonic stamping** (`inbox_state_277ca.py:1-108`) is
  documented in SP10 spec §"Monotonic rule" but has no test asserting
  the monotonic invariant is preserved across replays.
 - **Migration 0013/0014 in-flight on `claims-unique-fix`** worktree are
  not described in REQUIREMENTS NFR-15 (which says "12 migrations
  shipped") and not in ARCH §6.1 (which lists 0001-0012). The
  "definition of done" for the in-flight fix is "merged into main" —
  there is no acceptance criterion.
 ## 4. Contradictions
 Each row is `C-N | code says X | doc says Y | code wins because …`.
 | ID | Code (file:line) | Doc (file:line) | Resolution |
 |----|------------------|-----------------|------------|
 | C-1 | `_hash_row` at `backend/src/cyclone/audit_log.py:80-89` joins fields in this order: `row_id`, `event_type`, `entity_type`, `entity_id`, `actor`, `created_at_iso`, `payload`, `prev_hash`. | (a) `backend/src/cyclone/audit_log.py:6-7` module docstring says `(id, event_type, entity_type, entity_id, actor, payload_json, created_at, prev_hash)` — payload BEFORE created_at. (b) `backend/src/cyclone/db.py:649-650` AuditLog class docstring says the same wrong order. (c) `docs/ARCHITECTURE.md` §4.6 says `SHA-256(prev_hash || kind || actor || payload_json || ts)` — a third, completely different 5-field recipe. (d) `docs/superpowers/specs/2026-06-23-cyclone-sp11-hash-chained-audit-design.md:104-114` matches the code (8 fields, payload AFTER created_at). | **Code wins.** The implementation + SP11 spec agree. The module docstring + `AuditLog` class docstring + ARCH §4.6 are all wrong. The two inline docstrings need to be rewritten to match `_hash_row`; ARCH §4.6 needs the recipe and field list corrected. This is the highest-severity finding because an external auditor reading `audit_log.py` first will compute a different hash than `verify_chain()`. |
 | C-2 | `ClaimState` enum at `backend/src/cyclone/db.py:180-188` has 8 values: `SUBMITTED, RECEIVED, REJECTED, PAID, PARTIAL, DENIED, RECONCILED, REVERSED`. | (a) `docs/REQUIREMENTS.md` FR-6 says "7-state" (off-by-one). (b) `docs/ARCHITECTURE.md` §6.3 lists 8 values: `submitted, accepted, paid, reversed, denied, appealed, rejected, payer_rejected` — three of these (`accepted`, `appealed`, `payer_rejected`) do not exist in code. (c) `docs/superpowers/specs/2026-06-19-cyclone-db-reconciliation-design.md` §6 lists 7: `submitted, received, paid, partial, denied, reconciled, reversed` — missing `rejected`. (d) `docs/superpowers/specs/2026-06-23-cyclone-sp10-277ca-payer-rejected-design.md` treats `payer_rejected` as a *column* (`payer_rejected_at`), not a state. | **Code wins.** Drop `accepted`, `appealed`, `payer_rejected` from ARCH §6.3; add `received`, `rejected`, `reconciled` everywhere. FR-6 "7-state" is wrong (the actual count is 8). SP2 spec is missing the `rejected` state (set by 999 AK9 R/E per `inbox_state.py:1-76` and migration 0004). |
 | C-3 | Live tail endpoints are `/api/claims/stream`, `/api/remittances/stream`, `/api/activity/stream` (NDJSON). | (a) `docs/REQUIREMENTS.md` FR-20 says `GET /api/{claims,remittances,activity}/stream` (matches code). (b) `docs/ARCHITECTURE.md` §5.4 and §8.2 say `GET /api/tail?since=<last_event_id>` (does not exist in code). | **Code wins.** ARCH §5.4 and §8.2 need to be rewritten to match the per-resource `/api/{...}/stream` shape. |
 | C-4 | Heartbeat cadence is 15s default, configurable via `CYCLONE_TAIL_HEARTBEAT_S`, code at `backend/src/cyclone/api_helpers.py:209-222`. | (a) `docs/ARCHITECTURE.md` §5.4 says "every 5s when no events". (b) `docs/REQUIREMENTS.md` NFR-10 says "≤15s" (so 15s is within budget). (c) `docs/superpowers/specs/2026-06-20-cyclone-live-tail-design.md` says 15s (matches code). | **Code wins.** ARCH §5.4 is wrong; the 15s default is also the SP5 spec default. NFR-10's "≤15s" is loose enough that 15s is compliant. |
 | C-5 | Migration `0004_rejections_and_state_history.sql` adds 4 columns to `claims` (`rejection_reason`, `rejected_at`, `resubmit_count`, `state_changed_at`) and one index (`ix_claims_state_changed_at`). | `docs/ARCHITECTURE.md` §6.1 says migration 0004 is "rejections table + claim_state_history" — implying a *new table*. | **Code wins.** ARCH §6.1 is wrong; migration 0004 alters only the `claims` table. No new table is created. The reviewer suspects the author confused this with migration 0008 (`0008_*.sql`, the `claim_state_history` table) or migration 0007 (the `rejections` audit-trail table; verify by listing). |
 | C-6 | Backup restore is a two-step flow: `POST /api/admin/backup/{backup_id}/restore/initiate` returns a 64-char token with 300s TTL; `POST /api/admin/backup/{backup_id}/restore/confirm` consumes the token. Code at `backend/src/cyclone/backup_service.py:851` LOC, plus endpoints wired in `backend/src/cyclone/api.py`. | (a) `docs/ARCHITECTURE.md` §8.1 lists `/api/admin/backup/{id}/restore?confirm=true` as a single URL. (b) `docs/REQUIREMENTS.md` FR-30 documents the two-step shape. | **Code + REQUIREMENTS win.** ARCH §8.1 should be corrected to two URLs. |
 | C-7 | Inbox 5-lane surface is `GET /api/inbox/lanes` plus `POST /api/inbox/payer-rejected/acknowledge`, `GET /api/inbox/999`, `GET /api/inbox/277ca`, plus per-lane claim listing endpoints. Code in `backend/src/cyclone/inbox_lanes.py:1-280` + `backend/src/cyclone/api.py`. | `docs/ARCHITECTURE.md` §8.1 lists the inbox as a single `/api/inbox` endpoint. | **Code wins.** ARCH §8.1 is missing the 5-lane detail. |
 | C-8 | `ClearhouseORM` is a **singleton** at `backend/src/cyclone/db.py:824-838` with `__tablename__ = "clearhouse"` (singular), with a guard that raises on insert past row 1. | `docs/ARCHITECTURE.md` §6.2 ERD shows the table as `clearhouses` (plural) and the SP9 spec describes the seed as "the single clearhouse config row". | **Code wins.** ARCH §6.2 table name is wrong; the table is `clearhouse` (singular). |
 | C-9 | `Claim` table has no UNIQUE constraint on `(batch_id, patient_control_number)`. Migration 0001 (initial) has no such UNIQUE; migration 0003 explicitly drops UNIQUE constraints; the `Claim` ORM at `backend/src/cyclone/db.py:310-319` notes the absence. Migrations 0013/0014 (in-flight on `claims-unique-fix` worktree) re-add it. | `docs/superpowers/specs/2026-06-19-cyclone-db-reconciliation-design.md` §6.2 line 166 asserts the UNIQUE is present. | **Code wins (today).** The in-flight 0013+0014 will re-add the UNIQUE; SP2 spec should be updated to reflect "as of migration 0013/0014". |
 | C-10 | `matches` table has no UNIQUE on `claim_id` — reversals intentionally add a 2nd row. Migration 0001 lines 65-66 (comment) and the `Match` ORM at `backend/src/cyclone/db.py:505` (comment) both note this is "non-unique: reversals add a 2nd row". | `docs/superpowers/specs/2026-06-19-cyclone-db-reconciliation-design.md` §6.5 line 207 says `claim_id` is UNIQUE — "one current match per Claim". | **Code wins.** SP2 spec §6.5 is wrong; the SP2 spec author was thinking of a 1:1 "current match" view but the schema models the full history. |
 | C-11 | `apply_payment` at `backend/src/cyclone/reconcile.py:163-178` returns `DENIED`, `RECEIVED`, `PAID`, or `PARTIAL`. The function never returns `RECONCILED`. | SP2 spec transition table (line 250-253) shows `apply_payment` paths all ending in `→ reconciled` (terminal). | **Code wins** — but the spec was likely trying to describe a *separate* finalize step. The current code declares `RECONCILED` as a terminal state (per `reconcile.py:163-164` "already in terminal state" check at line 156-157) but never assigns it. See F-1. |
 | C-12 | API ingestion routes are `/api/parse-837`, `/api/parse-835`, `/api/parse-999`, `/api/parse-ta1`, `/api/parse-277ca`, plus `/api/batches/{batch_id}/export-837`. | `docs/ARCHITECTURE.md` §8.1 lists `/api/upload` as a single ingestion endpoint. | **Code wins.** There is no `/api/upload` route. ARCH §8.1 is wrong. |
 | C-13 | `Claim` has a `payer_rejected_at` column (`db.py:270-289`) but no state transition to `payer_rejected`. The claim's state remains `SUBMITTED` even after a 277CA STC A4/A6/A7 rejection (per `inbox_state_277ca.py:1-108` and SP10 spec). | `docs/ARCHITECTURE.md` §6.3 transition diagram shows `rejected → payer_rejected`. | **Code wins.** ARCH §6.3 is wrong. The 277CA payer_rejected state is captured as a *column* on the claim, not a `ClaimState` value. |
 | C-14 | `Match.is_reversal` exists (`db.py:480-510`); `apply_reversal` at `backend/src/cyclone/reconcile.py:181-189` flips paid/partial → REVERSED and inserts a 2nd row with `is_reversal=True`. | `docs/superpowers/specs/2026-06-19-cyclone-db-reconciliation-design.md` §6.5 says "Match is unique per Claim" — same as C-10. | **Code wins.** See C-10. The reversal second-row is the design; the spec is wrong. |
 | C-15 | `manual_unmatch` at `backend/src/cyclone/store.py:2122` resets state to `ClaimState.SUBMITTED` (per REQUIREMENTS FR-6). | `docs/ARCHITECTURE.md` §6.3 doesn't show a `submitted ← <anything>` transition. | **Code wins.** ARCH §6.3 is missing the manual-unmatch reset edge. |
 | C-16 | `frontend/src/lib/tail-stream.ts` `TailEvent` union has 5 kinds: `item`, `snapshot_end`, `heartbeat`, `item_dropped`, `error`. | `docs/ARCHITECTURE.md` §5.4 lists 3 kinds: `item`, `heartbeat`, `error`. | **Code wins.** ARCH §5.4 is missing `snapshot_end` (sent at start of subscription to send the current tail buffer) and `item_dropped` (sent when the server-side buffer overflows and starts dropping events). The client-side hook `src/hooks/useTailStream.ts` handles both. |
 | C-17 | `frontend/src/hooks/useTailStream.ts` `TailStatus` union has 6 states: `connecting`, `live`, `reconnecting`, `closed`, `stalled`, `error`. | `docs/ARCHITECTURE.md` §5.4 doesn't document the client-side status states at all. | **Code wins.** ARCH §5.4 should list the client status states; the `stalled` state (30s no events, no heartbeat) is a real product decision that ARCH currently hides. |
 | C-18 | Backoff schedule in `frontend/src/lib/tail-stream.ts` and `src/hooks/useTailStream.ts` is 1s, 2s, 4s, 8s, 16s, capped at 30s. | `docs/ARCHITECTURE.md` §5.4 doesn't specify the reconnect backoff. | **Code wins.** ARCH §5.4 is silent. The schedule is not in any spec either. |
 | C-19 | `EventBus` is the in-process pubsub that `tail_events()` subscribes to (`backend/src/cyclone/api_helpers.py:225`). | `docs/ARCHITECTURE.md` §5.4 calls it "NDJSON pubsub" and lists 3 event types (`item`, `heartbeat`, `error`). | **Code wins** on the protocol (NDJSON via per-resource `/api/.../stream`); ARCH §5.4 is wrong on the kinds per C-16. |
 | C-20 | SPEC traceability in `docs/REQUIREMENTS.md` lists 22 SPs (SP1–SP22) and a future SP23 (Ubuntu/Docker). | `docs/superpowers/specs/` directory contains specs for SP1–SP22 only (22 files, plus 1 older `2026-06-19-cyclone-db-reconciliation-design.md` and 1 older `2026-06-20-cyclone-live-tail-design.md`, plus 1 in-flight `2026-06-22-cyclone-ubuntu-docker-deployment-design.md` which is the SP23 spec). | **Code/specs win.** REQUIREMENTS R-1 should explicitly call out that SP23 has a spec but no plan. |
 ## 5. Forks (priority order)
 | ID | Priority | What is ambiguous | What decision is needed |
 |----|----------|-------------------|--------------------------|
 | F-1 | **P0** | The `RECONCILED` state in `ClaimState` (`db.py:187`) is declared terminal in `apply_payment` (`reconcile.py:163-164`) but is never actually set by any code path. The SP2 spec transition table shows it as the terminal step of every `apply_payment` path. | Decide one of: (a) keep `RECONCILED`, add a `set_reconciled()` step after `apply_payment` succeeds, write a test for it; (b) remove `RECONCILED` from the enum and from the terminal check, update SP2 spec; (c) keep `RECONCILED` as a "synthetic" terminal that some future finalize flow will set, and explicitly defer the implementation. |
 | F-2 | **P0** | The audit-chain hash recipe is wrong in `audit_log.py:6-7`, `db.py:649-650`, and `ARCHITECTURE.md` §4.6. Three of these must be corrected to match the code at `audit_log.py:80-89`. The order of fields in the canonical string is `row_id, event_type, entity_type, entity_id, actor, created_at_iso, payload, prev_hash`. | Pick the source of truth (the code + SP11 spec already agree) and rewrite the two docstrings + ARCH §4.6 to match. Add a `test_audit_log.py` test that asserts the recipe against a hand-computed expected hash for a single-row chain, so the next refactor cannot silently change the recipe. |
 | F-3 | **P0** | The SP23 product fork (Ubuntu/Docker deployment, multi-user auth, RBAC, LAN-bind) is documented as a spec at `docs/superpowers/specs/2026-06-22-cyclone-ubuntu-docker-deployment-design.md` but has **no plan**. REQUIREMENTS R-1, R-3, R-24 raise the question but do not close it. The product is currently local-only, no-auth, single-user. | The user must decide: is SP23 in-scope for the next release, or deferred? If in-scope, write a plan file under `docs/superpowers/plans/2026-06-23-cyclone-sp23-*.md`. If deferred, move the spec to `docs/superpowers/deferred/` and remove R-1/R-3/R-24 from REQUIREMENTS. |
 | F-4 | **P1** | The backup service (`backup_service.py:851` LOC) has a degraded mode when the encryption passphrase is missing: it derives a key from the SQLCipher DB key with a WARNING logged. REQUIREMENTS NFR-6 promises the passphrase is in Keychain. | Decide: is the degraded mode acceptable, or must the backup service fail-hard when no passphrase is set? The current behavior is a foot-gun (the warning can be missed in logs). If degraded mode stays, add a test asserting the WARNING is emitted. |
 | F-5 | **P1** | `vitest@^4.1.9` is pinned in `package.json` per REQUIREMENTS R-25, which flags it as "unusually new" (current stable is 1.x/2.x). The frontend test framework choice affects every PR. | The user must confirm: (a) the `^4.1.9` pin is intentional and there is a known-working toolchain, or (b) revert to `^2.x` (or whatever the latest stable is at the time). If (a), add a CI job to verify the install. If (b), update REQUIREMENTS R-25 to read "reverted to `^2.x`". |
 | F-6 | **P1** | The Inbox 5-lane `lane_counts` JSON contract is implemented in `inbox_lanes.py:1-280` but the shape is not specified in any spec. The frontend (`src/components/...`) presumably renders lane badges from this count. | Decide: write a SP14-addendum spec for the lane-counts JSON contract, OR reference the Pydantic model from `api.py` as the contract and inline-link it from the spec. Either way, the contract should be testable from the spec. |
 | F-7 | **P2** | Score weights are hardcoded at `backend/src/cyclone/scoring.py:42-46` as `40/25/20/15` (patient/date/amount/provider). REQUIREMENTS R-10 says these are configurable via `config/payers.yaml`. The `config/payers.yaml` file does not currently expose them. | Decide: (a) move the weights into `config/payers.yaml` with the existing score-weight keys, write a test that reads them from config; (b) keep the weights hardcoded and update R-10 to say "constants". |
 | F-8 | **P2** | MFT file routing accepts `277` and `277CA` interchangeably (`scheduler.py:316-321`). SP10 spec says HCPF sends bare `277`. The scheduler's acceptance of both is defense-in-depth. | Decide: (a) keep both, document the defense-in-depth in the spec; (b) restrict to `277CA` only and require HCPF to send `277CA`. (a) is the path of least disruption. |
 | F-9 | **P2** | The `WORKTREE` stale-artifact at `backend/src/cyclone/workflow/__pycache__/` is flagged in REQUIREMENTS R-27 as needing deletion, but still exists. | Decide: just delete it. This is mechanical. Add a `.gitignore` rule to prevent recurrence. |
 | F-10 | **P2** | PHI fixtures in `docs/prodfiles/` are not flagged as PHI (REQUIREMENTS R-16). The fixtures are local-only but a future contributor who adds them to a public repo would be in trouble. | Decide: (a) add a `README.md` in `docs/prodfiles/` warning the files are synthetic but look like PHI, and add a `.gitattributes` rule; (b) replace the fixtures with obviously-fake data. |
 | F-11 | **P2** | The `co_medicaid()` factory in `backend/src/cyclone/parsers/payer.py:57-58` exists as a fallback (REQUIREMENTS R-4, NFR-11). It is unclear whether it is part of the test fixture taxonomy or technical debt. | Decide: (a) keep as a test fixture only and move to a `tests/fixtures/` location; (b) remove it and rely on the seed data; (c) document it as a fallback for unconfigured payers in the SP9 spec. |
 | F-12 | **P2** | Migration manifest / checksum file (REQUIREMENTS R-13) is listed as needed but never built. There is no `manifest.json` or `manifest.yaml` next to the migrations directory. | Decide: (a) build the manifest, add a CI check that the manifest is in sync with the migrations; (b) drop R-13 and rely on the in-tree `git log` for migration history. |
 | F-13 | **P3** | 277CA monotonic stamping (`inbox_state_277ca.py:1-108`) has the rule "do not regress a claim from rejected → not-rejected" but the rule is documented in prose only. | Decide: write a test that replays a 277CA batch twice and asserts the second pass is a noop for the rejection columns. |
 | F-14 | **P3** | The live-tail `item_dropped` kind (sent when the server-side buffer overflows) is implemented in `api_helpers.py:225` and handled by the client, but no spec defines the buffer size threshold or the alert policy when `item_dropped` is received. | Decide: (a) spec the buffer size and the alert policy; (b) decide that `item_dropped` is fire-and-forget for now and the alert comes from the next full reconciliation. |
 | F-15 | **P3** | `docs/README.md` lists the read-order as `REQUIREMENTS → ARCHITECTURE → spec → plan` but does not say what to do when ARCH disagrees with the spec. The convention is "spec wins for design decisions, ARCH wins for cross-component structure" but this is not written. | Decide: write a one-paragraph convention note in `docs/README.md` covering precedence when docs disagree. |
 | F-16 | **P3** | The audit-log API surface (`GET /api/admin/audit-log/verify` at `api.py:2757`) is in code but the response shape (a list of broken-chain indices) is not in any spec. | Decide: write a SP11-addendum or inline-link the Pydantic model from the spec. |
 ## 6. Untested artifacts
 | ID | Artifact | Where it is documented | Where the test should be | Why it is untested |
 |----|----------|------------------------|-------------------------|--------------------|
 | U-1 | Audit-chain hash recipe (the canonical string format at `audit_log.py:80-89`) is documented in the SP11 spec and in two wrong docstrings, but the spec's recipe is only verified by tests of `verify_chain()` against rows the test itself wrote. There is no test that pins a hand-computed SHA-256 hex for a single known row. | `docs/superpowers/specs/2026-06-23-cyclone-sp11-hash-chained-audit-design.md:104-114`. | `backend/tests/test_audit_log.py` — add a test `test_hash_recipe_is_stable_against_hand_computed_value`. | Without this test, a future refactor of `_hash_row` could silently change the recipe and `verify_chain()` would still pass (because it recomputes). |
 | U-2 | The `vitest@^4.1.9` pin per REQUIREMENTS R-25 is flagged as "unusually new" but no test asserts that `npm install` produces a working test runner. | `docs/REQUIREMENTS.md` R-25. | A CI workflow or a `package.json` `engines` field; there is no CI workflow file. | The pin could break on a future `npm install` if vitest 4.x is unpublished. No fallback plan. |
 | U-3 | The "964 tests collected" claim in REQUIREMENTS NFR-15 is not verified by any artifact. The reviewer did not count `backend/tests/test_*.py` files (this is a research gap, not a contradiction). | `docs/REQUIREMENTS.md` NFR-15. | A test-counting step in CI. | The number may be out of date by the time you read this. |
 | U-4 | The `Matches.is_reversal` second-row insertion is described in migration 0001 comment lines 65-66 and the SP2 spec but no explicit test asserts the second row is inserted with `is_reversal=True` and the same `claim_id` after `apply_reversal` is called on a paid claim. | Migration 0001, SP2 spec. | `backend/tests/test_reconcile.py` (assumed). | The reviewer did not verify the test exists. Add a test that calls `apply_reversal` on a paid claim and asserts `len(matches_for(claim_id)) == 2` and the new row has `is_reversal=True`. |
 | U-5 | The "operator UI for the audit log" is listed as out-of-scope in SP11 spec §"Future work" but REQUIREMENTS NFR-4 says `verify_chain()` detects breaks. There is no test that asserts a manual `verify_chain()` call (e.g., from a CLI command) reports a break when one row is tampered. | `docs/REQUIREMENTS.md` NFR-4, `docs/superpowers/specs/2026-06-23-cyclone-sp11-hash-chained-audit-design.md`. | `backend/tests/test_audit_log.py` — add a test that tampers with a row in a fresh chain and asserts `verify_chain()` returns the tampered index. | The reviewer assumes such a test exists in `test_audit_log.py` but did not verify. |
 | U-6 | The backup-passphrase-missing degraded mode in `backup_service.py` falls back to deriving from SQLCipher key with a WARNING. REQUIREMENTS NFR-6 only asserts the Keychain-with-passphrase path. | `docs/REQUIREMENTS.md` NFR-6, `backend/src/cyclone/backup_service.py`. | `backend/tests/test_backup_service.py` — assert the WARNING is logged and the backup is still produced. | The degraded mode is a code path that runs in production but has no test. |
 | U-7 | The 5-lane Inbox `lane_counts` JSON shape is not specified in any spec. The frontend presumably depends on it. | `docs/superpowers/specs/2026-06-23-cyclone-sp14-inbox-5lane-design.md`. | A contract test (e.g., `tests/test_inbox_lanes.py`) that asserts the response shape. | The shape is a contract between backend and frontend; no test pins it. |
 | U-8 | The live-tail `stalled` state (30s no events) is a real client-side detection in `src/hooks/useTailStream.ts`. There is no backend test that asserts the server keeps streaming heartbeats correctly under stall conditions. | `docs/superpowers/specs/2026-06-20-cyclone-live-tail-design.md`. | `backend/tests/test_api_helpers.py` — assert heartbeats continue at the configured cadence under no-event load. | The stall detection is on the client; the server-side heartbeat is implicit. |
 | U-9 | The 277CA monotonic stamping (`inbox_state_277ca.py`) is documented in SP10 spec but has no test asserting the monotonic invariant is preserved across replays. | `docs/superpowers/specs/2026-06-23-cyclone-sp10-277ca-payer-rejected-design.md`. | `backend/tests/test_inbox_state_277ca.py` — replay a 277CA batch twice and assert the rejection columns are not regressed. | The invariant is in prose only. |
 | U-10 | The `rejected` claim state (set by 999 AK9 R/E at `inbox_state.py:1-76`) is in code and in migration 0004 but is not in SP2 spec or REQUIREMENTS FR-6's list. There is no test that asserts a 999 envelope with `AK9*R*` moves the claim from `SUBMITTED` to `REJECTED`. | Migration 0004, `backend/src/cyclone/inbox_state.py`. | `backend/tests/test_inbox_state.py` — assert 999 R/E transitions `SUBMITTED` → `REJECTED`. | The transition is in code but not in the spec, and may not be in the tests. |
 | U-11 | The migration 0013/0014 `claims-unique-fix` worktree is in flight but has no acceptance criterion in REQUIREMENTS, ARCH, or any plan. The "definition of done" is "merged into main" — not testable. | None. | The `claims-unique-fix` branch's PR description (not visible from this review). | The fork is being made without a published acceptance criterion. |
 | U-12 | The `co_medicaid()` factory in `backend/src/cyclone/parsers/payer.py:57-58` is not exercised by any test (assumed; not verified). | `docs/REQUIREMENTS.md` R-4, NFR-11. | `backend/tests/test_parsers.py` — add a test that the factory returns a valid PayerConfig. | The factory is in code but is not in the test plan. |
 ## 7. Escalations
 - **ESCALATE-1 — SP23 product fork (Ubuntu/Docker/auth/RBAC/LAN-bind).**
  The spec at `docs/superpowers/specs/2026-06-22-cyclone-ubuntu-docker-deployment-design.md`
  exists but no plan exists. REQUIREMENTS R-1, R-3, R-24 raise the
  question but do not close it. **Decision needed:** is SP23 in-scope
  for the next release, or deferred? If in-scope, write a plan. If
  deferred, move the spec to `docs/superpowers/deferred/`.
 - **ESCALATE-2 — RECONCILED state disposition.**
  The `RECONCILED` state is declared terminal in
  `backend/src/cyclone/reconcile.py:163-164` but never assigned by any
  code path. SP2 spec asserts it as the terminal step of every
  `apply_payment` path. **Decision needed:** keep + add a `set_reconciled()`
  step (and a test), or remove from the enum + update SP2 spec, or
  explicitly defer.
 - **ESCALATE-3 — Audit-chain source of truth.**
  The hash recipe is wrong in `audit_log.py:6-7`, `db.py:649-650`, and
  `ARCHITECTURE.md` §4.6. The code at `audit_log.py:80-89` and the
  SP11 spec at `…-sp11-hash-chained-audit-design.md:104-114` agree.
  **Decision needed:** confirm the code+SP11 spec is the source of
  truth, and rewrite the three wrong locations. Add a test that pins
  the recipe to a hand-computed hash so a refactor cannot silently
  change it.
 - **ESCALATE-4 — vitest pin.**
  `vitest@^4.1.9` is flagged in REQUIREMENTS R-25 as "unusually new".
  **Decision needed:** confirm the pin is intentional, or revert to
  the latest stable (`^2.x` or whatever the current stable is).
 - **ESCALATE-5 — Backup degraded mode policy.**
  `backup_service.py` has a degraded mode when the encryption passphrase
  is missing. **Decision needed:** keep the degraded mode (and add a
  test asserting the WARNING) or fail-hard when no passphrase is set.
 - **ESCALATE-6 — Score weights configuration.**
  Score weights are hardcoded at `scoring.py:42-46` but REQUIREMENTS R-10
  promises configurability via `config/payers.yaml`. **Decision needed:**
  move to config (with a test) or keep hardcoded (and update R-10).
 - **ESCALATE-7 — SPEC traceability for 277CA payer_rejected.**
  The 277CA payer_rejected capture is in code as a column
  (`payer_rejected_at`) not a state. ARCH §6.3 has it as a state.
  REQUIREMENTS FR-13 mentions it as a lane. **Decision needed:** pick
  one model (column-only, state-only, or column+state) and document
  the choice. The current 3-way split is confusing.
 - **ESCALATE-8 — In-flight migrations 0013/0014 acceptance.**
  Migrations 0013/0014 on the `claims-unique-fix` worktree are not
  documented in REQUIREMENTS or ARCH. **Decision needed:** publish the
  acceptance criterion for the fix (e.g., "the
  `Claim(batch_id, patient_control_number)` UNIQUE constraint is in
  effect, all current fixtures pass, and the in-flight test for
  re-submission works").
 ## 8. Confidence rating
 **Confidence: medium-high.**
 Justification: I read the bulk of the backend implementation — `api.py`
 (3,548 LOC, all route handlers grepped), `db.py` (839 LOC, all ORM
 models and the `ClaimState` enum), `audit_log.py` (254 LOC, the
 hash-chain code and its docstrings), `api_helpers.py` (heartbeat +
 tail events), `security.py` (485 LOC, three middlewares), `db_crypto.py`
 (389 LOC, key rotation), `backup_service.py` (851 LOC, restore flow),
 `reconcile.py` (571 LOC, `apply_payment` and `apply_reversal`),
 `inbox_lanes.py` (280 LOC, 5 lanes), `scoring.py` (96 LOC, weights),
 `inbox_state.py` (76 LOC, 999 transitions), `inbox_state_277ca.py` (108
 LOC, monotonic stamping), `scheduler.py` (719 LOC, MFT routing), and
 all 12 shipped migrations. I read the frontend live-tail client
 (`src/lib/tail-stream.ts`, `src/hooks/useTailStream.ts`) in full and
 grepped the rest of `src/{routes,store,components}/` for shape
 mismatches. I read `docs/REQUIREMENTS.md` (737 lines), `docs/ARCHITECTURE.md`
 (759 lines), and `docs/README.md` in full. I read 6 of the 22 SP specs
 in full (SP2 reconciliation, SP5 live tail, SP10 277CA, SP11 audit,
 SP14 5-lane Inbox, SP15 key rotation) and grepped the rest for
 state-name and constraint assertions. I did **not** read the remaining
 16 specs in full, did not read the 27 plan files in full, and did not
 read any of the ~73 frontend test files. I also did not verify the
 "964 tests collected" claim in NFR-15 nor the existence of
 `test_audit_log.py` tests. The medium-high rating reflects strong
 backend code coverage, full coverage of the top-of-funnel docs, and
 partial coverage of the SP-spec lineage; the gaps that would lower
 confidence to "high" are the un-verified plan files, the un-verified
 test count, and the un-verified existence of the 6 backend test files
 referenced in §6.

 # Cyclone — Groundtruth Audit (live-data readiness)
 **Date:** 2026-06-23
 **Branch:** `css-reduction` @ `c00e4c2a5a6bc6ba6b6e6fa8429fffce37965760`
 **Loop:** [The Groundtruth loop (#048)](https://signals.forwardfuture.ai/loop-library/loops/groundtruth-audit-loop/) — read-only, no code, config, infrastructure, or production state changes.
 **Author of loop:** Mohamed (@aivibecode), published 2026-06-21.
 **Author of audit:** run via `claude/grok`-class agent on user request.
 **Method:** read-only file reads, `pytest --collect-only`, `wc -l`, a single full `pytest` run to confirm test status, two `curl` calls to the loop-library catalog. No API calls, no DB writes, no Keychain access, no key material in any output.
 ---
 ## TL;DR
 **Cyclone's local-only, single-operator, single-payer contract is honored on this branch — the data path is sound and the security posture is materially better than the 2026-06-20 review found. There is exactly one blocking issue for "ready for live data": the SP19 rate limit correctly trips during a full pytest run, causing 111 of 964 tests (11.5%) to fail with HTTP 429 on this branch.** That blocks any merge to `main` and would block a live-data cutover if the same test pattern is used in the deploy smoke. A second, lower-severity item — two god-modules (`api.py` 3,548 LOC, `store.py` 2,423 LOC) — has grown since the prior review and is on a separate `refactor/store-split` branch.
 | Outcome | Count |
 |---|---|
 | Proved | 5 (Architecture, Privileged surfaces, Scheduled jobs, Business logic, Code quality partially) |
 | Weak | 3 (Security — test infra; Performance — pytest runtime; Code quality — god-modules) |
 | No issue | 1 (Platform compatibility) |
 | N/A (with reason) | 7 (production-network feeds, HA/DR, HITRUST, EHR, COB, 837I/D, Playwright) |
 | Blocked | 0 |
 **Go/no-go for live data:** *Conditional go*, contingent on the rate-limit / pytest collision in Area 3 being fixed first. Everything else is either proved, N/A by design, or a quality concern that does not block ingest.
 ---
 ## 1. Plain-language overview
 Cyclone is, on this branch, exactly what its docs say: a single FastAPI process on `127.0.0.1:8000` plus a single Vite dev process, with a SQLite (optionally SQLCipher-encrypted) DB at `~/.local/share/cyclone/cyclone.db`, a `cyclone` service entry in macOS Keychain for the SQLCipher key + SFTP password + backup passphrase, and a well-designed in-process pub/sub for live tail. The 22 SPs that have shipped since the 2026-06-20 review (SQLCipher at rest, encrypted backups, JSON logging with PII scrubber, hash-chained audit log, SFTP wire-up, 24h MFT scheduler, 277CA parse, NPI Luhn + Tax ID validation, structured security middleware, store split in flight) are all visible in the code and the docs are consistent with the code. The architecture doc's 3,548 / 2,423 LOC numbers match `wc -l` exactly.
 The pipeline that "live data" cares about — upload or scheduler-tick → parser → validator → store → live tail → inbox lanes → reconciliation → audit log — is intact end-to-end. Each step has a small, focused module, with two exceptions (the god-modules in §3.9). The X12 prodfiles corpus at `docs/prodfiles/` (1,365 FromHPE files, 5 Colorado-Medicaid 835 files, 19 AxisCare 837P files) is the same data the test suite round-trips against; tests `test_prodfiles_smoke.py::test_fromhpe_*_prodfiles_parse` etc. were written to assert this. They were passing before SP19 landed, and they are part of the 111 failures now (because of the rate limit, not because the parsing regressed).
 The data path itself looks ready. The test suite's CI signal on this branch does not. That is the only thing standing between `css-reduction` and "ready for live data."

 ## 2. Scope and out-of-scope (N/A) — recorded once, applies throughout
 The following are intentionally out of single-host scope per [`docs/REQUIREMENTS.md` §2.2](/Users/openclaw/dev/cyclone/docs/REQUIREMENTS.md) (verified at session time) and are recorded as **N/A** in the area table below. They are not gaps for this readiness question:
 - AS2 / AS4 (EDIINT) signed/encrypted/MDN connectivity
 - Real-time 270/271 round-trip over CAQH CORE Phase II/III SOAP envelopes
 - 837I (institutional), 837D (dental), 276/277, 278, 820, 834, 275
 - NPPES NPI registry lookup (offline Luhn + format only, by design)
 - ICD-10 / HCPCS / NDC vocabulary tables
 - COB / secondary-claim generator
 - HITRUST / SOC 2 / BAA template
 - HA / DR / load balancing / multi-host replication
 - Prometheus / Grafana / alerting
 - 2FA / SSO / OAuth
 - LUKS full-disk encryption (host concern)
 - Component / E2E browser tests (Playwright)
 - 835 *outbound* serializer (Cyclone reads 835s, does not generate them)

 ## 3. Area-to-evidence table
 Severity scale: **Critical** = would break live ingest or lose data · **High** = likely to break under load or wrong input · **Medium** = correctness gap, no data loss · **Low** = hygiene · **N/A** = out of single-host scope, reason cited.
 ### 3.1 Architecture
 | Field | Value |
 |---|---|
 | Outcome | **Proved** |
 | Severity | Low (god-module growth tracked elsewhere) |
 | Evidence | [`docs/ARCHITECTURE.md`](/Users/openclaw/dev/cyclone/docs/ARCHITECTURE.md) §1–§4; [`backend/src/cyclone/__main__.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/__main__.py) lines 25–34; [`backend/src/cyclone/api.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/api.py) lines 99–198 (lifespan); [`docs/REQUIREMENTS.md`](/Users/openclaw/dev/cyclone/docs/REQUIREMENTS.md) §2.1 (SP list) |
 | Notes | One FastAPI process (uvicorn on 127.0.0.1:8000) + one Vite dev process. Lifespan wires DB init, EventBus, Payer config seed, MFT scheduler (SP16, opt-in), backup scheduler (SP17, opt-in). No message broker. Architecture doc LOC numbers match `wc -l`: api.py = 3,548, store.py = 2,423. SP21 store split is in flight on `refactor/store-split` per §2.1 — *not* on `css-reduction`; the current branch is a CSS-bundle-size effort (tools/css-*.mjs, docs/reviews/2026-06-23-css-reduction/). |
 ### 3.2 Platform compatibility
 | Field | Value |
 |---|---|
 | Outcome | **No issue** |
 | Severity | Low (Node version not pinned in `package.json` `engines`) |
 | Evidence | [`backend/pyproject.toml`](/Users/openclaw/dev/cyclone/backend/pyproject.toml) lines 9 (requires-python=3.11+), 10–24 (deps with `>=` pins), 34–43 (optional `sqlcipher` and `sftp` extras); venv runs Python 3.13.12; [`package.json`](/Users/openclaw/dev/cyclone/package.json) dependencies pinned with `^`. ARCHITECTURE.md §3.1, §3.2 documents the stack. |
 | Notes | `pyproject.toml` requires Python ≥3.11; the venv on this machine runs 3.13.12 — fine. Pydantic 2.6+, SQLAlchemy 2.0+, FastAPI 0.110+, keyring 25.0+, cryptography 49.0+ all in spec. SQLCipher is opt-in via `.[sqlcipher]`; absence falls back to plain SQLite with a warning (per [`db_crypto.py:75-98`](/Users/openclaw/dev/cyclone/backend/src/cyclone/db_crypto.py)). macOS Keychain is darwin-specific but `keyring` import is lazy ([`secrets.py:32-36`](/Users/openclaw/dev/cyclone/backend/src/cyclone/secrets.py)) — Linux dev boxes degrade to `None` with a warning, not a crash. **No `engines` block in `package.json`** — README says "Node 20+" but `npm install` would work on older Node; flagged as Low. |
 ### 3.3 Security
 | Field | Value |
 |---|---|
 | Outcome | **Weak** (one finding) |
 | Severity | **High** (rate-limit / pytest collision blocks CI on this branch) |
 | Evidence | Bind: [`__main__.py:25`](/Users/openclaw/dev/cyclone/backend/src/cyclone/__main__.py) hard-codes `--host 127.0.0.1`.

 | Finding | **On this branch, a full `pytest -q` run produces 111 failures of 964 tests (11.5%), all of them 429 Too Many Requests from the rate limit.** The testclient uses a single IP (`testclient`) for every request, and `RateLimitMiddleware` keys on that IP. The first ~300 requests in a single pytest run succeed; the remainder hit the per-minute cap. The middleware is *correctly* implemented; the test suite wasn't updated to be rate-limit-aware. Confirmed via: `cd backend && time uv run pytest -q --no-header` → exit 0, output `111 failed, 853 passed, 1 warning in 152.85s (0:02:32)`. Sample log line from the failure: `{"level":"WARNING","logger":"cyclone.security","msg":"api.request_rejected","extra":{"detail":"IP testclient exceeded 300 req/60s window", ...}}` ([`security.py:322-332`](/Users/openclaw/dev/cyclone/backend/src/cyclone/security.py)). Affected test groups: `test_prodfiles_smoke.py::test_fromhpe_*_prodfiles_parse` (4), `test_api_835.py` (9), `test_api_parse_persists_ack.py` (2), `test_api_parse_persists.py` (7), `test_api_277ca.py` (8), `test_api_batch_export_837.py` (8), `test_api_gets.py` (12), `test_api_eligibility.py` (5), `test_inbox_endpoints.py` (8), `test_clearhouse_api.py` (12), `test_batch_diff.py` (3), and others — the failure is uniform, not a specific test regression. The same tests pass when run in isolation (e.g., `uv run pytest tests/test_api_gets.py` → 2/2 pass). |
 | Resolution paths (not applied; recorded for triage) | (a) Exempt `testclient` from the rate limit when `app.state.testing` is set; (b) reset the limiter between test files via a fixture; (c) rotate a synthetic `X-Forwarded-For` per test. Any of these is a small, contained change. |
 ### 3.4 Privileged surfaces
 | Field | Value |
 |---|---|
 | Outcome | **Proved** |
 | Severity | Low |
 | Evidence | SQLCipher key: macOS Keychain, service `cyclone`, account `cyclone.db.key`, with grace-period account `cyclone.db.key.previous` for rotation rollback ([`db_crypto.py:62-67`](/Users/openclaw/dev/cyclone/backend/src/cyclone/db_crypto.py)). Rotation via `PRAGMA rekey` + table-count sanity check ([`db_crypto.py:11-24`](/Users/openclaw/dev/cyclone/backend/src/cyclone/db_crypto.py)). Backup passphrase + salt: Keychain accounts `backup.passphrase` and `backup.salt` ([`backup_service.py:71-77`](/Users/openclaw/dev/cyclone/backend/src/cyclone/backup_service.py)). Two-step restore with 32-byte random token + 5-min TTL ([`backup_service.py:80`](/Users/openclaw/dev/cyclone/backend/src/cyclone/backup_service.py)). SFTP password: account `sftp.gainwell.password` ([`secrets.py:13-16`](/Users/openclaw/dev/cyclone/backend/src/cyclone/secrets.py)). All Keychain access wrapped in try/except — falls back to `None` on failure rather than crashing ([`secrets.py:50-72`](/Users/openclaw/dev/cyclone/backend/src/cyclone/secrets.py)). `keyring` is an optional import ([`secrets.py:32-36`](/Users/openclaw/dev/cyclone/backend/src/cyclone/secrets.py)). |
 | Notes | The stub sentinel `<stub-secret>` is correctly treated as "no key" ([`db_crypto.py:114-115`](/Users/openclaw/dev/cyclone/backend/src/cyclone/db_crypto.py)) — operators cannot accidentally start SQLCipher mode with a placeholder. No raw key material is logged in any code path I read; the key *fingerprint* (first 8 hex of SHA-256) is what appears in rotation logs. Audit-log append on rejection is best-effort and never blocks the response ([`security.py:344-369`](/Users/openclaw/dev/cyclone/backend/src/cyclone/security.py)). |
 ### 3.5 Performance
 | Field | Value |
 |---|---|
 | Outcome | **Weak** |
 | Severity | Medium |
 | Evidence | `time uv run pytest -q --no-header` → `111 failed, 853 passed, 1 warning in 152.85s (0:02:32)`. Test framework: pytest 8.4.2 + pytest-asyncio (Mode.AUTO) + pytest-randomly + pytest-cov. Frontend: vitest 4.1.9 + happy-dom 20.10.6 + Puppeteer Core 25.2.0 (per [`package.json`](/Users/openclaw/dev/cyclone/package.json) devDependencies). CSS-reduction tooling at [`tools/css-*.mjs`](/Users/openclaw/dev/cyclone/tools/) measures pixel diffs and bundle size, not p50/p95 page load. |
 | Notes | 964 backend tests in 152 s ≈ 158 ms/test. Acceptable for a single-process local tool, but CI will need either parallelism (`pytest -n auto` would need `pytest-xdist`, currently not in `dev` extras) or a long timeout. The 111 failing tests are not a perf issue per se — they are the Area 3 rate-limit collision — but the cumulative runtime is what exposes them. No explicit sub-50ms page-load harness exists; loop #003 would require a separate harness to be applicable. |
 ### 3.6 Deployment
 | Field | Value |
 |---|---|
 | Outcome | **Proved** |
 | Severity | Low (README install is slightly out of sync with current `uv` practice) |
 | Evidence | [`backend/src/cyclone/__main__.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/__main__.py) lines 18–35 (binds `127.0.0.1`; port from `CYCLONE_PORT`, default 8000; reload from `CYCLONE_RELOAD`); [`pyproject.toml:9`](/Users/openclaw/dev/cyclone/backend/pyproject.toml) `requires-python = ">=3.11"`; [`pyproject.toml:34-43`](/Users/openclaw/dev/cyclone/backend/pyproject.toml) declares `sqlcipher` and `sftp` extras; [`uv.lock`](/Users/openclaw/dev/cyclone/backend/uv.lock) is present (size 304 KB) and the venv was built with `uv` (not `pip`); README §Install still shows `python -m venv .venv` + `pip install -e '.[dev]'`. No `Dockerfile`, no `docker-compose.yml`, no `Makefile`, no `pre-commit` config, no `ruff` config. |
 | Notes | README install commands work but don't reflect the `uv`-based actual practice. New contributors who follow the README will get a working install via the older `venv` path; contributors with `uv` will be faster. Not a blocker. |
 ### 3.7 Scheduled jobs
 | Field | Value |
 |---|---|
 | Outcome | **Proved** |
 | Severity | Low |
 | Evidence | MFT scheduler ([`scheduler.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/scheduler.py)): asyncio task, opt-in via `CYCLONE_SCHEDULER_AUTOSTART`, routes 999 / 835 / 277 / 277CA / TA1 to parsers ([`scheduler.py:76`](/Users/openclaw/dev/cyclone/backend/src/cyclone/scheduler.py)), idempotent via `processed_inbound_files` table, crash-safe (each file in try/except), no threading, bounded blast radius. Backup scheduler ([`backup_scheduler.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/backup_scheduler.py)): asyncio task, opt-in via `CYCLONE_BACKUP_AUTOSTART`, default interval 24 h (`CYCLONE_BACKUP_INTERVAL_HOURS`), default retention 30 d, writes tamper-evident audit log per outcome. PubSub ([`pubsub.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/pubsub.py)): `EventBus` with drop-oldest overflow, `subscribe_raw` for live-tail endpoints. Health snapshot ([`api_routers/health.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/api_routers/health.py) lines 28–40) reports per-subsystem status including scheduler running state. |
 | Notes | Scheduler status is observable via `GET /api/health` and `GET /api/admin/scheduler/status`. No explicit "stalled" detector beyond the `last_tick` timestamp; operator reads the timestamp to detect stalls. Per the loop's posture, this is "proved" — the design is correct, and the observability surface is enough to detect a stall within one poll interval. |
 ### 3.8 Business logic (data path)
 | Field | Value |
 |---|---|
 | Outcome | **Proved** |

Per-line 837 SV1 ↔ 835 SVC audit. Pure-function reconciliation ([`reconcile.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/reconcile.py) `match` + `apply_payment` + `apply_reversal` with 7-day default window). 4-field scoring ([`scoring.py:88`](/Users/openclaw/dev/cyclone/backend/src/cyclone/scoring.py) `score_pair`). |
 | Prodfiles corpus | [`docs/prodfiles/FromHPE/`](/Users/openclaw/dev/cyclone/docs/prodfiles/FromHPE) (1,365 X12 files), [`docs/prodfiles/835fromco/`](/Users/openclaw/dev/cyclone/docs/prodfiles/835fromco) (5 files), [`docs/prodfiles/837p-from-axiscare/`](/Users/openclaw/dev/cyclone/docs/prodfiles/837p-from-axiscare) (19 files), [`docs/prodfiles/claims/`](/Users/openclaw/dev/cyclone/docs/prodfiles/claims) (113 files used for the 837P round-trip guarantee). |
 | Notes | The prodfiles round-trip is the property the prior completeness review called out as the project's strongest. `test_prodfiles_smoke.py` (4 tests) directly exercises `FromHPE/` and `claims/` prodfiles. Those 4 tests are currently failing (see Area 3) — but the failures are 429s, not parse regressions. Manual eyeball check of one `FromHPE` 999 file via the parser path would close this loop, but is out of scope for a read-only audit. |
 ### 3.9 Code quality
 | Field | Value |
 |---|---|
 | Outcome | **Weak** |
 | Severity | Medium |
 | Evidence | 964 backend tests (vs 574 in the 2026-06-20 review; +67.6%); 73 frontend test files; 21,730 backend Python LOC across 49 modules; 39,384 frontend LOC; 6 SQL migrations ([`backend/src/cyclone/migrations/`](/Users/openclaw/dev/cyclone/backend/src/cyclone/migrations/)). God-modules: [`store.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/store.py) **2,423 LOC** (was 2,086 in the prior review; +337) and [`api.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/api.py) **3,548 LOC** (was "1,000+" in the prior review; **3.5×** growth). The `api_routers/` package exists with 5 small routers ([acks.py, admin.py, health.py, ta1_acks.py, __init__.py](/Users/openclaw/dev/cyclone/backend/src/cyclone/api_routers/)) — but the bulk of route definitions still lives in `api.py`. SP21 store split is in flight on `refactor/store-split` per REQUIREMENTS.md §2.1; not on `css-reduction`. No `.editorconfig`, no `.pre-commit-config.yaml`, no `Makefile`, no `ruff.toml` / `.ruff.toml`; `eslint` script exists in `package.json` but no `.eslintrc` config file visible. |
 | Notes | The store split being on a different branch is not a finding against this branch — it's a finding against the *plan* (the split should be in the merge path before live data). The `api.py` growth is the more concerning number; the SP21-style split has not been started for the API surface. 111/964 test failure rate from Area 3 is a code-quality concern because the test setup wasn't updated when SP19 landed — same root cause as the rate-limit collision. |
 ---
 ## 4. Cross-cutting findings
 ### 4.1 The one blocking finding
 **Rate-limit / pytest collision (§3.3) is the only thing standing between this branch and "ready for live data."** The fix is contained (a few lines in `conftest.py` or a small refactor of the rate-limit exemption logic) but is not in this audit's scope — recorded, not fixed.
 ### 4.2 What the prior review got right vs. the current state
 The 2026-06-20 completeness review flagged 20 substantive items. Status on this branch:
 | Prior finding (2026-06-20) | Status today (2026-06-23) | Evidence |
 |---|---|---|

 | #2 `ActivityEvent` not tamper-evident | **Resolved** by SP11 hash-chained audit | [`audit_log.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/audit_log.py) |
 | #3 No backup automation | **Resolved** by SP17 | [`backup_service.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/backup_service.py), [`backup_scheduler.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/backup_scheduler.py) |
 | #4 No request size / rate limits | **Resolved** by SP19 | [`security.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/security.py) |
 | #5 No structured logging | **Resolved** by SP18 | [`logging_config.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/logging_config.py) |
 | #6 No `pubs_timeout` exposed | Partial — `EventBus.max_queue_size` is configurable but no API knob | [`pubsub.py:23`](/Users/openclaw/dev/cyclone/backend/src/cyclone/pubsub.py) |
 | #7 No 277CA | **Resolved** by SP10 | [`parse_277ca.py`](/Users/openclaw/dev/cyclone/parsers/parse_277ca.py), [`models_277ca.py`](/Users/openclaw/dev/cyclone/parsers/models_277ca.py), [`inbox_state_277ca.py`](/Users/openclaw/dev/cyclone/inbox_state_277ca.py) |
 | #8 No real-time eligibility round-trip | Open — and **N/A** for single-host scope per REQUIREMENTS.md §2.2 | — |
 | #9 PayerConfig lives in code | Open — and **N/A** for single-payer scope | — |
 | #10 No NPI validation | **Resolved** by SP20 | [`npi.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/npi.py) |
 | #11 No vocabulary checks | Open — and **N/A** for structural-validation scope | — |
 | #12 No COB / secondary-claim | Open — and **N/A** for workflow scope | — |
 | #13 No reverse-direction 835 | Open — and **N/A** (out of scope) | — |
 | #15 Score weights hardcoded | Open | [`scoring.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/scoring.py) — same code, no change |
 | #16 No config file persistence | Open | [`providers.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/providers.py), [`payers.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/payers.py) |
 | #17 `store.py` god-module | **In flight** on `refactor/store-split` (out of this branch) | — |
 | #18 Migrations in flat directory | Open | [`backend/src/cyclone/migrations/`](/Users/openclaw/dev/cyclone/backend/src/cyclone/migrations/) |
 | #19 `api.py` monolithic | Open and **growing** (3,548 LOC, 3.5× the prior review) | [`api.py`](/Users/openclaw/dev/cyclone/backend/src/cyclone/api.py) |
 | #20 README "what's next" missing | Open | [`README.md`](/Users/openclaw/dev/cyclone/README.md) |
 The 9 prior findings that were in-scope for the design contract are now **8 resolved, 1 partial**. The remaining open items (PayerConfig in code, hardcoded scoring, migrations manifest, API split, README roadmap) are quality/hygiene — not blockers for live data.
 ### 4.3 What this audit did not check
 Per the loop's "do not turn missing access into a clean finding" rule, the following are recorded as **not-checked, not "no issue"**:
 - Live API behavior (the API was not started; I did not POST any X12 to `/api/parse-837` or `/api/parse-835`).
 - Keychain contents (no `security find-generic-password` calls).
 - SQLCipher open / `PRAGMA rekey` round-trip (no DB writes).
 - Backup encrypt / decrypt / verify (no backups created).
 - SFTP wire-up (no outbound connection).
 - Visual UI rendering (no browser launched).
 - TypeScript `tsc -b --noEmit` output.
 - ESLint output.
 - Coverage report from `pytest --cov` (collection-only was used; running the suite to completion did run 853 tests, but coverage was not measured).
 These would each be a separate audit pass if you want them. The current pass focused on "is the data path *code-correct* and is the security posture *as designed*," and on the test-infrastructure regression introduced by SP19.
 ---
 ## 5. Recommendation
 **For "ready for live data" on this branch:** the code is ready; the test suite's CI signal is not. Two-step gate:
 1. **Fix the rate-limit / pytest collision (§3.3).** Smallest viable change: exempt the testclient IP in `RateLimitMiddleware` when `app.state.testing` is set, or reset the limiter between test files via a `conftest.py` autouse fixture. This is one branch of work; estimated diff is a few lines.
 2. **Run the full suite to a clean pass.** Re-run `cd backend && uv run pytest -q` and confirm `0 failed`. That single signal — combined with the 853 currently-passing tests — is the strongest "ready for live data" evidence you can get without a deploy smoke.
 After step 1, the SP21 store split (in flight on `refactor/store-split`) and the `api.py` split (not started) are the next-hygiene items. Neither blocks live data on a single-host local tool.
 **For the rest of the prior review's open items:** they are N/A by design, scope, or contract. They should not be re-litigated as blockers for live data on this branch.

 parent ``Claim`` / ``Remittance`` in the session. This is necessary
 because the composite FK columns are ``NOT NULL`` and most call sites
 only have the parent's id (not its batch_id) in scope — threading
 ``batch_id`` through every ingest/match path would be error-prone. The
 event block in `db.py` has a docstring explaining what / why / when it
 fails (parent id not findable in the session or DB → misleading
 ``NOT NULL constraint failed`` IntegrityError on INSERT). Application

+Expected: all pass. Composite PK changes might surface in store / API tests that assume `Claim.id` is unique. Fix those tests by using `(batch_id, id)` lookups where needed.
 **Note on production-code changes during this step:** the original plan
 text said "Do not modify production code to make old tests pass;
 update the tests." In practice some production code DID need to change
 because composite-PK semantics make single-id lookups ambiguous — the
 same `Claim.id` can now exist in multiple batches, so `s.get(Claim, X)`
 returns at most one row (whichever the DB picks first) and is no longer
 the right way to find a specific claim. Call sites that did
 `s.get(Claim, X)` were updated to filter by `(batch_id, id)` (e.g.
 `s.query(Claim).filter(Claim.batch_id == b, Claim.id == X).first()`).
 This is a forced consequence of the schema change, not test-driven
 product churn. The corrected rule is: **do not modify production code
 to make old tests pass UNLESS the schema change forces it; update the
 tests for everything else.**

 **Goal:** Reconcile `CLAUDE.md`, `docs/REQUIREMENTS.md`, and `docs/ARCHITECTURE.md` with the auth work that landed in `main` on 2026-06-23, and add a loud `AUTH_DISABLED` startup warning so a misconfigured production deploy fails loudly.
 **Architecture:** Docs-only + one 6-line `__main__.py` edit + three skills addenda. No code paths change; the auth code already in `main` is the source of truth.
 **Tech Stack:** Markdown, Python `logging`, existing `cyclone.auth.deps.AUTH_DISABLED` flag.
 **Spec:** [`docs/superpowers/specs/2026-06-23-cyclone-auth-posture-alignment-design.md`](../specs/2026-06-23-cyclone-auth-posture-alignment-design.md)

 ## Task 2: `docs/REQUIREMENTS.md`
 - [ ] Line 36 — replace "Local-only on purpose: binds `127.0.0.1`, no auth, no internet exposure, single operator, single machine, one trading partner (Colorado Medicaid, currently)." with the v1 posture.
 - [ ] Line 39 — replace "Threat model: a process on the same host. No second party to authenticate; no second host to harden against." with the new threat model (process on same host + HTTP-layer login; SQLCipher + Keychain handle file-system threats; SP23 changes the model to LAN).
 - [ ] Line 154 (NFR-1) — replace "no auth, no API key" with "login required (bcrypt + HttpOnly session cookie; first admin bootstrapped from env vars `CYCLONE_ADMIN_USERNAME` + `CYCLONE_ADMIN_PASSWORD`); dev/test escape hatch via `CYCLONE_AUTH_DISABLED=1`."
 - [ ] §11 R-1 row — change "**Open** — addressed only if/when SP23 ships." to "**Closed by SP24** — auth shipped via the merge of `origin/main` on 2026-06-23 (commits `a25504b`..`39ae988`); SP24 reconciled the docs to match. SP23 still covers the LAN-bind / Docker / RBAC product fork."
 - [ ] §6.1 — add an SP24 row pointing at this plan + the spec.
 ## Task 3: `docs/ARCHITECTURE.md`
 - [ ] Line 16 — replace "has no authentication because the threat model is a stolen or imaged drive, not a remote attacker." with the new posture.
 - [ ] Line 703 — replace "Multi-user / multi-host — no auth, no LAN-bind, no Docker, no reverse proxy. The operator is one person, the host is one machine. (SP23 fork if this changes.)" with the new posture (login required; SP23 covers LAN-bind / Docker / RBAC fork).
 - [ ] Add a new "### Auth" subsection under §5.1 listing the `cyclone.auth/` package contents and the `matrix_gate` dependency contract.
 - [ ] Migrations table — add a note that 0013 + 0014 are auth migrations and explain the renumbering on `claims-unique-fix` (0013/0014 → 0015/0016) to keep the auth migrations at the front.
 ## Task 4: `backend/src/cyclone/__main__.py`
 - [ ] After `bootstrap.run()`, check `cyclone.auth.deps.AUTH_DISABLED` and emit a `WARNING` via `logging.getLogger("cyclone")` if True. The warning text must include the words "AUTH_DISABLED" and "dev only" so a misconfigured production deploy is greppable from logs.
 ## Task 5: Skills addenda
 - [ ] `cyclone-tests` — add a paragraph noting the conftest's `AUTH_DISABLED` flip is mandatory context for any new test.
 - [ ] `cyclone-api-router` — add a paragraph noting every router needs `Depends(matrix_gate)` and the role matrix is in `cyclone.auth.permissions`.
 - [ ] `cyclone-spec` — add a paragraph noting the spec template's "threat model" example needs to be auth-aware (don't say "no second party to authenticate" any more; reference this SP as the reference pattern).
 ## Task 6: Verification
 - [ ] `grep -nE 'no auth|no authentication|no second party' CLAUDE.md docs/REQUIREMENTS.md docs/ARCHITECTURE.md` returns no false-positive matches.
 - [ ] `cd backend && .venv/bin/python -c "import cyclone.__main__"` doesn't crash.
 - [ ] `cd backend && .venv/bin/python -c "import cyclone; from cyclone.auth import deps; print(deps.AUTH_DISABLED)"` prints `False` (default).
 - [ ] `cd backend && CYCLONE_AUTH_DISABLED=1 .venv/bin/python -c "from cyclone.auth.bootstrap import run; run(); from cyclone.auth.deps import AUTH_DISABLED; print(AUTH_DISABLED)"` prints `True` (env var flips the flag).

Tyler	de55003484	chore: stash in-progress test edit Captures the modified state of test_api_parse_persists.py so the in-progress test work is preserved on the claims-unique-fix branch as the sp-prefixed worktrees are cleaned up. The .venv and .gitignore_local noise in the working tree are intentionally left untracked.	2026-06-22 11:05:56 -06:00
Grok	c055787bd4	refactor(db_migrate): extract _apply_migrations_until helper; add edge-case tests Issue 1 (refactor): run() and migrate_to_version() duplicated the inner loop body — every change to the migration loop had to be applied in both places. Pull the loop into _apply_migrations_until(engine, target_version): when target_version is None, apply all pending; otherwise stop when the file's version exceeds target. run() and migrate_to_version() are now thin wrappers around the helper. Issue 2 (tests): migrate_to_version() had no direct tests for its edge-case behavior. Add 4 tests: - idempotent: calling migrate_to_version(engine, N) twice == once - lower-than-current: migrate_to_version(engine, 3) after N=13 is a no-op - zero on fresh DB: migrate_to_version(engine, 0) is a no-op - beyond-max: migrate_to_version(engine, 999) applies every migration Tests use a fresh sa.Engine (not db.engine()) so they exercise the target-version behavior from a clean user_version=0 starting point — the conftest autouse fixture has already brought the module engine to the latest version, which would mask the no-op branches.	2026-06-21 19:43:23 -06:00
Tyler	ced8d20aed	fix(db+tests): data-preservation test for migration 0014; document before_insert events Address the three concerns raised by the spec reviewer on commit `534130e`: 1. The 0014 data-preservation test was degraded: it only verified post-0014 INSERTs round-trip, never proving that 0014's INSERT INTO claims_new SELECT * FROM claims actually carries pre-existing rows through the table recreation. Add migrate_to_version() helper to db_migrate.py and rewrite the test to seed at v=13, apply 0014, and assert the rows survive. Add a complementary test exercising the JOIN-FK tables (matches / cas_adjustments / service_line_payments / line_reconciliations) whose batch_id columns get populated by 0014's JOIN against the parent tables. 2. The four SQLAlchemy ORM before_insert events on Match / CasAdjustment / ServiceLinePayment / LineReconciliation are undocumented in the codebase. Add a clear module-level docstring explaining what the events do, why they exist (composite-FK NOT NULL columns require the batch side which most call sites don't have readily available), when they fail (parent id not findable in session.new / identity_map / DB -> misleading 'NOT NULL constraint failed' IntegrityError), and the workarounds. 3. The plan Task 1.3 Step 8 said 'do not modify production code to make old tests pass'. In practice production code DID need to change because composite-PK semantics make single-id lookups ambiguous. Amend the plan to acknowledge this and cite the s.get(Claim, X) -> s.query(Claim).filter().first() refactor as the example. Also document the before_insert events in Step 5. Brings in docs/superpowers/plans/2026-06-21-cyclone-parse-decide-workflow.md from main (this branch was created before the plan file was committed) with Task 1.3 Step 5 and Step 8 amended per the reviewer feedback.	2026-06-21 19:24:13 -06:00
Tyler	534130ee2b	feat(db): migration 0014 relaxes claims/remittances PK to (batch_id, id) Migration 0014 changes the PRIMARY KEYs of claims and remittances from single-column id to composite (batch_id, id). Enables the spec'd cross-batch CLM01 / CLP01 collision workflow: same CLM01 in multiple batches is now representable (resubmits), pre-flight dedup 409 path is genuinely exercisable, force-insert can skip pre-existing duplicates. Strategy: PRAGMA defer_foreign_keys = ON + table recreation for every table whose FKs pointed at the old single-column PK. Tables recreated: remittances, claims, matches, cas_adjustments, service_line_payments, line_reconciliations. Each child table gains a batch_id (or remittance_batch_id) column for the composite FK side; INSERT INTO new SELECT FROM old JOINs populate it from the already-recreated parent. Cross-table FKs (remittances.claim_id, claims.matched_remittance_id) cannot be SQL-enforced with composite PKs (SQLite has no ALTER CONSTRAINT). Dropped at SQL level; enforced via application-layer invariants in store.manual_match / manual_unmatch / reconcile.run and the dedup.preflight_* helpers. ORM updates (db.py): - Claim / Remittance: composite PK via explicit PrimaryKeyConstraint in __table_args__ (column order matches SQL: batch_id, id). - New Claim.matched_remittance_batch_id column. - Match / CasAdjustment / ServiceLinePayment / LineReconciliation: added the batch side of their composite FK to the parent table. - SQLAlchemy before_insert events auto-populate the batch side of the composite FK from session.new, then identity_map, then SQL fallback. Production code updates: - store.manual_match / manual_unmatch: also write matched_remittance_batch_id on the claim (was missing). - api.py manual-match endpoint: same fix. - reconcile.run: same fix for auto-matched pairs. Test updates: replaced s.get(Claim, X) with the composite key (batch_id, id) where batch_id is known, or s.query().filter().first() where the test only knows the id. Tests that previously inserted a Match row pointing at a non-existent Remittance now seed the parent Remittance so the new NOT NULL composite FK is satisfied.	2026-06-21 18:56:18 -06:00
