 name: cyclone-api-router
 description: "Cyclone FastAPI router conventions (api_routers/, api_helpers.py, response shapes, error envelopes). Use when: adding or changing an HTTP endpoint, splitting a route out of api.py, or wiring a new helper into api_helpers.py."

 # cyclone-api-router
 Cyclone splits its FastAPI surface two ways: small resource-group
 routers live in `backend/src/cyclone/api_routers/<topic>.py` and are
 mounted bare into `api.py`; the high-traffic streaming and parse
 endpoints still live as top-level decorators in `api.py` itself. This
 skill codifies the conventions so additions stay consistent with the
 four routers already shipped (`acks`, `admin`, `health`, `ta1_acks`).
 As of this writing: **4 router modules** under
 `backend/src/cyclone/api_routers/`, **one shared helpers module** at
 `backend/src/cyclone/api_helpers.py` (248 lines, NDJSON primitives +
 content negotiation + `tail_events`), and ~30 routes still inlined
 in `backend/src/cyclone/api.py`. The next refactor target is the
 parse endpoints.
 ## When to use
 - **Adding an endpoint.** You're adding a new GET / POST handler —
  you need to know whether it belongs in `api.py` (parse / streaming)
  or in a new router under `api_routers/`, and what the response
  shape and test file conventions look like.
 - **Splitting a route.** You're moving a route out of `api.py` into a
  dedicated `api_routers/<topic>.py` module and need the import /
  mounting rules (`from cyclone.api_routers import <topic>` then
  `app.include_router(<topic>.router)`).
 - **Adding a helper.** You're wiring a new function into
  `api_helpers.py` (NDJSON primitive, content-negotiation probe,
  tail-event helper) and need to keep it private to the API layer.
 - **Defining an error response.** You're raising from a route handler
  and need the conventional `HTTPException(status_code=..., detail=...)`
  shape used everywhere else in the API surface.
 ## Conventions
 1. **No new top-level routes in `api.py` for resource groups.** Any
   endpoint grouped under a resource (`/api/<resource>` and its
   `/{id}` detail) lives in `backend/src/cyclone/api_routers/<topic>.py`
   as an `APIRouter`. The streaming list endpoints (`/api/claims/stream`,
   `/api/remittances/stream`, `/api/activity/stream`) and the parse
   endpoints (`/api/parse-*`) currently stay in `api.py` because they
   span multiple store modules — don't move them unless you're also
   restructuring the store split.
 2. **Reuse `api_helpers.py`.** NDJSON primitives (`ndjson_line`,
   `ndjson_stream_list`, `ndjson_stream_837`, `ndjson_stream_835`),
   content negotiation (`client_wants_json`, `wants_ndjson`), the
   strict / `raw_segments` rewrites (`strict_rewrite_837`,
   `strict_rewrite_835`, `drop_raw_segments_837`, `drop_raw_segments_835`),
   and the shared live-tail generator (`tail_events`,
   `heartbeat_seconds`) all live there. Don't duplicate them in a
   router. The module's docstring (`api_helpers.py:1-18`) declares it
   private to the API layer — no business logic, no DB writes.
 3. **Response shape.** Every successful response is a **plain dict**
   produced by a per-router `<entity>_to_ui(row)` helper (see
   `_ack_to_ui` at `api_routers/acks.py:29-48` and `_ta1_to_ui` at
   `api_routers/ta1_acks.py:23-37`). This dict shape **must** match
   the matching `<entity>_written` event payload so live-tail pages
   don't drift (see `cyclone-store` for the serializer contract).
   Errors use FastAPI's `HTTPException` with a `detail` dict of the
   form `{"error": "<Title>", "detail": "<message>"}` —
   `acks.py:85-88`, `ta1_acks.py:72`. There is **no** shared
   `ErrorEnvelope` Pydantic model; the `detail` dict is the contract.
 4. **Mounting.** Routers are mounted bare in `api.py:251-256` —
   `app.include_router(<name>.router)` with **no** `prefix=`
   argument. Each `@router.<verb>` decorator carries the **full**
   `/api/<resource>` path itself (see `acks.py:51,75`,
   `ta1_acks.py:49,67`, `admin.py:23`, `health.py:28`). The
   `router = APIRouter()` declaration carries no `tags=` either —
   keep it minimal.
 5. **Streaming endpoints.** Use
   `StreamingResponse(media_type="application/x-ndjson")` and feed it
   either `ndjson_stream_list(items, total, returned, has_more)` (for
   list pages) or `tail_events(request, bus, kinds)` (for live-tail
   pages). See `acks.py:62-66` for the list-stream skeleton and
   `api.py:1357-1401` for the full live-tail pattern (snapshot →
   `snapshot_end` → subscription → heartbeats). See `cyclone-tail`
   for the wire format.
 6. **Tests.** Every new endpoint gets a `test_api_<topic>_<verb>.py`
   under `backend/tests/` (see `cyclone-tests` for the naming
   convention + autouse `conftest.py`). Existing examples:
   `test_api_validate_provider.py` (admin),
   `test_api_parse_persists_ack.py` (acks).
 ## Patterns
 ### A new `APIRouter` skeleton
 Pattern from `backend/src/cyclone/api_routers/acks.py:1-72`. Module
 docstring names the resource, imports the shared helpers, declares
 `router = APIRouter()` with no prefix, and defines a `_foo_to_ui(row)`
 mapper at module scope.
 ```python
 """``/api/foo`` — list & detail endpoints for <topic>."""
 from __future__ import annotations
 from fastapi import APIRouter, HTTPException, Query, Request
 from fastapi.responses import StreamingResponse
 from cyclone.api_helpers import ndjson_stream_list, wants_ndjson
 from cyclone.store import store
 router = APIRouter()
 def _foo_to_ui(row) -> dict:
    """Map a Foo ORM row to the UI shape used by ``/api/foo``."""
    return {"id": row.id, "name": row.name}
@router.get("/api/foo")
 def list_foo(
    request: Request,
    limit: int = Query(100, ge=1, le=1000),
 ):
    """Return the list of persisted Foo rows, newest first."""
    rows = store.list_foo()
    items = [_foo_to_ui(r) for r in rows[:limit]]
    total = len(rows)
    returned = len(items)
    has_more = total > returned
    if wants_ndjson(request):
        return StreamingResponse(
            ndjson_stream_list(items, total, returned, has_more),
            media_type="application/x-ndjson",
        )
    return {"items": items, "total": total, "returned": returned, "has_more": has_more}
 ```
 ### A `get_<topic>` detail endpoint with 404
 Pattern from `api_routers/acks.py:75-104` and `ta1_acks.py:67-76`.
 Path param is `<entity>_id` (not `id`) so it doesn't shadow
 FastAPI's internal `id` and the OpenAPI docs stay self-describing.
 ```python
@router.get("/api/foo/{foo_id}")
 def get_foo(foo_id: int) -> dict:
    """Return one persisted Foo row with its parsed detail.
    Path param is ``foo_id`` (not ``id``) to avoid shadowing
    FastAPI's internal ``id`` name and to keep OpenAPI docs
    self-describing. Returns 404 when the row is missing — never 500.
    """
    row = store.get_foo(foo_id)
    if row is None:
        raise HTTPException(
            status_code=404,
            detail={"error": "Not found", "detail": f"Foo {foo_id} not found"},
        )
    return _foo_to_ui(row)
 ```
 ### Mounting in `api.py`
 Pattern from `backend/src/cyclone/api.py:246-256`. The block lives
 just after middleware registration and just before the first
 `@app.<verb>` decorator.
 ```python
 # Resource-group routers. Each module owns its own APIRouter and is
 # registered below. New resources go in `cyclone.api_routers.<name>`
 # and are wired in here.
 from cyclone.api_routers import acks, admin, health, ta1_acks  # noqa: E402
 app.include_router(health.router)
 app.include_router(acks.router)
 app.include_router(ta1_acks.router)
 app.include_router(admin.router)
 ```
 ## Anti-patterns
 - **Don't import from `cyclone.api` into a router — the dependency runs the other way.** Routers are mounted *into* `api.py` (`api_routers/acks.py` etc. know nothing about `cyclone.api`). A circular import would silently break the `from cyclone.api_routers import ...` block at `api.py:251`.
 - **Don't introduce Pydantic response models where the codebase returns dicts.** Every existing list / detail endpoint returns a plain dict produced by a `<entity>_to_ui(row)` helper (see `acks.py:29-48`, `ta1_acks.py:23-37`). That dict shape **is** the event payload that `<entity>_written` carries — see `cyclone-store`. Introducing a Pydantic model on one side drifts the event payload from the list shape and silently breaks live-tail dedup.
 - **Don't bypass `CycloneStore` to query the ORM directly from a route.** Always call `store.<method>(...)` (`store.list_acks()`, `store.get_ta1_ack(ack_id)`) so the read path picks up the same session + snapshot serializer as the live-tail subscriber. A raw `with db.SessionLocal()() as s: s.get(Foo, foo_id)` in a handler bypasses the serializer contract and breaks the event-payload match. See `cyclone-store`.
 - **Don't set `prefix=` on `APIRouter`.** Mount the router bare (`app.include_router(<name>.router)`) and put the full `/api/<resource>` path in the decorator. Mixing the two styles scatters the URL across two files and breaks `grep "/api/foo"` audits.
 ## Related skills
 - **`cyclone-store`** — most routes call `store.<method>(...)` and the dict payload **is** the `<entity>_written` event payload; load when adding a route so the read path stays aligned with the pubsub contract.
 - **`cyclone-tail`** — streaming endpoints (`/api/<resource>/stream`) and the NDJSON wire format; load when adding a live-tail route or changing the wire format.
 - **`cyclone-edi`** — parse endpoints (`/api/parse-837`, `/api/parse-835`, `/api/parse-999`, `/api/parse-ta1`, `/api/parse-277ca`) currently live in `api.py`; load when adding or changing a parse endpoint.
 - **`cyclone-tests`** — endpoint tests follow the `test_api_<topic>_<verb>.py` naming under `backend/tests/`; load when writing the test for a new endpoint.

 # cyclone-cli
 The operator-facing CLI is a **Click** group at `cli.py:45` (`@click.group()` for `main`), mounted as the `cyclone` console script in `pyproject.toml:54` (`cyclone = "cyclone.cli:main"`). Seven subcommands ship today: `parse-837`, `parse-835`, `validate-npi`, `validate-tax-id`, plus the `backup` group (`init-passphrase`, `create`, `list`, `verify`, `restore`, `prune`, `status`). `serve` lives separately in `__main__.py:19` (dispatches `uvicorn cyclone.api:app`).
 ## When to use
 - **Adding a subcommand.** You need a new operator command (e.g. `cyclone rotate-key`) and want to match the existing Click decorator + smoke-test rhythm.
 - **Changing an exit code.** You're tweaking which `sys.exit(N)` a subcommand raises and need the 0/1/2 contract used by `parse_837`, `parse_835`, `validate_npi_cmd`, `validate_tax_id_cmd`, and the `backup` group.
 - **Adding a smoke test.** You need `backend/tests/test_cli_<name>.py` using `click.testing.CliRunner` (NOT `subprocess.run`) and want the canonical fixture + monkeypatch layout (Keychain stub, fresh SQLite, `CYCLONE_BACKUP_DIR`).
 - **Wiring a security-sensitive command.** Anything touching `cyclone/secrets.py` (Keychain writes), DB key rotation, or destructive restores needs the two-step confirm dance used by `backup restore` / `backup prune` (`cli.py:462,509`).
 ## Conventions
 1. **Click decorator pattern, not argparse.** Each subcommand is a
   top-level function decorated with `@main.command("<name>")` and
   one `@click.option` / `@click.argument` per parameter. Group
   dispatch is implicit — no `set_defaults(func=...)` and no
   `cmd_<name>(args) -> int` signature. Top-level commands at
   `cli.py:77,151,241,261,303`; the `backup` sub-group nests a
   second `@main.group()` (`cli.py:303`) with its own
   `@backup.command("<name>")` children.
 2. **Long-form flags for safety.** Prefer `--rotate-key`,
   `--backup-dir`, `--from-stdin` over positional args for anything
   that mutates state or takes a secret. `init-passphrase`
   (`cli.py:308-311`) demonstrates the canonical "flag OR stdin"
   pattern: `--passphrase` for automation, `--from-stdin` for
   interactive `getpass()` prompting.
 3. **Exit codes: 0 / 1 / 2.** `0` = success. `1` = user / input
   error (invalid NPI/EIN at `cli.py:258,277,285`; Keychain write
   failure at `cli.py:341,351`; tampered-backup verify at
   `cli.py:459`). `2` = operator / parse error
   (`CycloneParseError` at `cli.py:106,178`; passphrase
   empty/mismatch/short at `cli.py:331,337`). Document the codes
   in the docstring (see `validate_npi_cmd` at `cli.py:244-250`).
   Use `click.UsageError(...)` for usage mistakes; reserve
   `sys.exit(2)` for "the file failed to parse" semantics.
 4. **Smoke test with `click.testing.CliRunner`.** Every new
   subcommand gets `backend/tests/test_cli_<name>.py` that
   imports `from cyclone.cli import main` and invokes via
   `CliRunner().invoke(main, [...], catch_exceptions=False)`. The
   test must stub Keychain (`monkeypatch.setattr(secrets_mod,
   "get_secret"/"set_secret", ...)`) and pin a temp SQLite DB via
   `CYCLONE_DB_URL` + `db._reset_for_tests()` — see
   `backend/tests/test_cli_backup.py:13-69` for the canonical
   `_cli_env` fixture. CliRunner captures output and exit codes
   in-process; do NOT shell out to `subprocess.run`.
 5. **Destructive ops need `--yes` + `click.confirm(abort=True)`.**
   `backup restore` (`cli.py:462-506`) and `backup prune`
   (`cli.py:509-537`) both gate the destructive action behind a
   `--yes` is_flag and an interactive `click.confirm(..., abort=True)`
   prompt. CliRunner auto-aborts confirm prompts, so smoke tests
   assert `exit_code != 0` when `--yes` is omitted
   (`test_cli_backup.py:122-137`). A `--dry-run` flag is NOT yet
   implemented anywhere; if needed, mirror the `--yes` pattern.
 ## Patterns
 ### A Click subcommand — `@main.command("<name>")` + options
 From `cli.py:241-258` (smallest standalone subcommand):
 ```python
@main.command("validate-npi")
@click.argument("npi")
@click.option("--log-level", default="WARNING", show_default=True,
              type=click.Choice(["DEBUG", "INFO", "WARNING", "ERROR"]))
 def validate_npi_cmd(npi: str, log_level: str) -> None:
    """Validate a 10-digit NPI's Luhn checksum locally (SP20). Exit 0 valid, 1 invalid. PHI — don't log the value."""
    setup_logging(level=log_level)
    from cyclone.npi import is_valid_npi
    if is_valid_npi(npi):
        click.echo(f"OK: {len(npi)}-digit NPI passes Luhn checksum")
        return
    click.echo(f"INVALID: {npi!r} fails NPI Luhn checksum", err=True)
    sys.exit(1)
 ```
 ### A smoke test — `CliRunner` + Keychain stub + temp SQLite
 From `test_cli_backup.py:13-69`. Stable hex salt keeps multiple `CliRunner` invocations consistent within one test. The `Batch` seed at `cli_backup.py:27-35` is omitted — only the Keychain + DB plumbing is the convention:
 ```python
@pytest.fixture
 def _cli_env(tmp_path, monkeypatch):
    from cyclone import db, secrets as secrets_mod
    from cyclone import backup_service as svc_mod
    monkeypatch.setenv("CYCLONE_DB_URL", f"sqlite:///{tmp_path}/test.db")
    db._reset_for_tests()
    db.init_db()
    # ... seed any DB rows the subcommand needs (see cli_backup.py:27-35) ...
    store = {svc_mod.KEYCHAIN_BACKUP_PASSPHRASE_ACCOUNT: "cli-test-passphrase",
             svc_mod.KEYCHAIN_BACKUP_SALT_ACCOUNT:
                 "0123456789abcdef0123456789abcdef"}
    monkeypatch.setattr(secrets_mod, "get_secret", lambda n: store.get(n))
    monkeypatch.setattr(secrets_mod, "set_secret",
                        lambda n, v: store.__setitem__(n, v) or True)
    monkeypatch.setenv("CYCLONE_BACKUP_DIR", str(tmp_path / "backups"))
    yield tmp_path / "backups"
    db._reset_for_tests()
 def test_backup_create_list_verify_status(_cli_env):
    from cyclone.cli import main
    runner = CliRunner()
    r = runner.invoke(main, ["backup", "create"], catch_exceptions=False)
    assert r.exit_code == 0, r.output
    assert "created backup id=" in r.output
 ```
 ### A destructive subcommand — `--yes` + `click.confirm(abort=True)`
 From `cli.py:462-506` (`backup restore`). Two-step: announce, prompt unless `--yes`, then execute. Restore uses an explicit init/confirm round-trip so the operator can back out between phases. Matching smoke test asserts the guard fires:
 ```python
@backup.command("restore")
@click.argument("backup_id", type=int)
@click.option("--yes", is_flag=True, help="Skip the interactive confirm prompt")
@click.option("--actor", default="operator-cli", show_default=True)
 def backup_restore(backup_id: int, yes: bool, actor: str) -> None:
    """Restore the live DB from a backup (two-step, requires --yes)."""
    # ... db.init_db() + service config omitted ...
    click.echo(f"Initiating restore from backup {backup_id}...")
    init = svc.restore_initiate(backup_id)
    # ... echo init summary (filename, fp, table_count, ttl) ...
    if not yes:
        click.confirm(
            "Replace the live DB with this backup? "
            "This will dispose the engine and rebuild it.",
            abort=True,
        )
    click.echo("Confirming restore...")
    result = svc.restore_confirm(backup_id, init.restore_token, actor=actor)
 def test_backup_restore_requires_yes_flag(_cli_env):
    runner = CliRunner()
    runner.invoke(main, ["backup", "create"], catch_exceptions=False)
    r = runner.invoke(main, ["backup", "restore", "1"], catch_exceptions=False)
    # CliRunner auto-aborts confirm prompts → exit_code != 0.
    assert r.exit_code != 0
 ```
 ## Anti-patterns
 - **Don't `sys.exit(2)` for usage errors.** Reserve code 2 for
  parse/operator errors (`CycloneParseError`, Keychain not
  initialized, passphrase policy violation). For "you passed the
  wrong flag" use `raise click.UsageError(...)` — Click formats
  it as a clean help message and exits 2 on its own.
 - **Don't print errors to stdout.** Use `click.echo(msg, err=True)`
  for all error output. `print(..., file=sys.stderr)` and bare
  `logging.error(...)` bypass Click's stdout/stderr split and leak
  into test `result.output` — breaking `assert "FAIL" in r.output`
  style assertions.
 - **Don't add a subcommand without a smoke test.** Every new
  `@main.command(...)` ships a sibling
  `backend/tests/test_cli_<name>.py` exercising the happy path
  AND at least one error path (missing input, invalid arg,
  tampered ciphertext — see `test_cli_backup.py:102-119`).
 - **Don't reuse the `parse` command name.** Existing subcommands
  are type-specific (`parse-837`, `parse-835`); a generic `parse`
  would shadow them or force an `--type` flag — neither is the
  codebase pattern.
 ## Related skills
 - **`cyclone-store`** — `backup` subcommands and the parse
  subcommands both round-trip through `CycloneStore` and the DB
  session; load when the increment changes write paths or the
  `<entity>_written` event contract.
 - **`cyclone-api-router`** — `cyclone serve` (via `__main__.py:19`)
  launches the FastAPI app; the CLI parse subcommands share the
  same `CycloneParseError` exception and Pydantic result models
  as the matching HTTP endpoints.
 - **`cyclone-edi`** — `parse-837` / `parse-835` are the CLI smoke
  entry points for the parser/validator surface; load when adding
  a parser or R-code rule.
 - **`cyclone-tests`** — every CLI subcommand gets a pytest smoke
  case under `backend/tests/test_cli_<name>.py`; the `_cli_env`
  fixture pattern (fresh SQLite + Keychain stub) is documented
  there.
 - **`cyclone-spec`** — load when the SP-N spec introduces a new operator command or reserves a new exit-code category.

 As of this writing: **7 parser modules** under `backend/src/cyclone/parsers/parse_<edi>.py`, **~25 per-claim rules** numbered `R010`–`R100` and `R200`–`R210` in `validator.py`, plus a parallel set of **835-specific rules** prefixed `R835_*` in `validator_835.py`. The next increment is **SP22**.
 ## When to use
 - **Adding or changing a parser.** You are about to touch `backend/src/cyclone/parsers/parse_<edi>.py` or its paired `models_<edi>.py` and need the orchestrator signature, the segment walker convention, and the re-export in `parsers/__init__.py`.
 - **Adding a validator rule.** You are writing a new `_rule_R<n>_<name>` (or `_r<n>_<name>` per the existing snake-case style) and need the rule signature, the R-code numbering scheme, and the `ValidationIssue` shape.
 - **Wiring a new CAS / CARC code.** The 835 carries Claim Adjustment Reason Codes in `CAS` segments; the lookup lives in `backend/src/cyclone/parsers/cas_codes.py` and the UI reads through `claim_status_label()`.
 - **Debugging a parse failure on a prodfiles sample.** You dropped a real EDI file into `docs/prodfiles/<source>/` and the parser is choking — load this skill to confirm the tokenizer path, the orchestrator entry point, and which fixture in `backend/tests/fixtures/` matches the transaction type.
 ## Conventions
 1. **Parser signature.** Every parser module exports exactly one public entry function. Two flavors coexist in the codebase:
   - `parse(text: str, *, input_file: str = "") -> <TypedResult>` — used by `parse_270.py:337`, `parse_271.py:356`.
   - `parse(text: str, payer_config: <PayerConfig>, input_file: str = "") -> <TypedResult>` — used by `parse_837.py:319` and `parse_835.py:459` because both need payer-specific config to validate segments against.
   - `parse_<edi>_text(text: str, *, input_file: str = "") -> <TypedResult>` — the legacy name-suffixed form, still in use at `parse_ta1.py:143`, `parse_999.py:220`, `parse_277ca.py:280`. The `<TypedResult>` is always a Pydantic model from `models_<edi>.py` (or co-located `models.py` for 837P).
 2. **Segment walk.** Parsers consume `backend/src/cyclone/parsers/segments.py` — there are exactly three public pieces: `Delimiters` (frozen dataclass holding the four ISA-derived separators), `_detect_delimiters(isa_segment)` (private), and `tokenize(text) -> list[list[str]]` (returns ISA prepended as the first segment). Parsers then index into the `list[list[str]]` directly — there is **no** `Segment` / `Loop` / `next_segment` helper class. Whole-document problems (missing ISA, wrong transaction set) raise `CycloneParseError`; per-segment problems on acks (999/277CA) are surfaced on the result, not raised.
 3. **Validator rules.** Numbered rules live in `backend/src/cyclone/parsers/validator.py` (for 837P — R010–R100 general + R200–R210 SP9 CO MAP / HCPF naming) and `backend/src/cyclone/parsers/validator_835.py` (for 835 — names prefixed `R835_*` because the same numeric space would collide with 837P). Each rule is a function `_r<n>_<name>(claim: ClaimOutput, cfg: PayerConfig) -> Iterable[ValidationIssue]` registered in the module-level `_RULES` list and run by `validate(claim, config)`. Issues carry the rule name as a stable string (`rule="R021_npi_checksum"`) — the R-code **is** how the UI surfaces the error, so never invent an unnumbered rule.
 4. **NPI / EIN / CAS format logic.** Identity-format checks live in their own modules — never duplicate them in a parser or validator:
   - `backend/src/cyclone/npi.py` — `is_valid_npi(npi)` runs the Luhn checksum with the `80840` NPPES prefix; `is_valid_tax_id(ein)` enforces `XX-XXXXXXX` (or 9 raw digits).
   - `backend/src/cyclone/parsers/cas_codes.py` — `reason_label(group, reason)` and `all_known_codes()` for the CARC lookup; snapshot date is exported as `LAST_UPDATED`.
   - `backend/src/cyclone/parsers/models_271.py` — `SERVICE_TYPE_CODES` + `service_type_description()` for 271 EB benefit codes.
 5. **Prodfiles reuse.** When adding a parser for a new transaction type, ship at least one fixture in `backend/tests/fixtures/<edi>/<sample>.txt` (the existing 13 fixtures are **flat** at the top level of `fixtures/` — no per-test subdirectories). Copy from `docs/prodfiles/<source>/<file>.txt`; never reach into `docs/prodfiles/` from a test. The matching test should declare the path as a module-level `Path` constant.
 ## Patterns
 ### Minimal `parse_<edi>.py` — using `segments.py`, exporting `parse_ta1_text`
 Taken from `backend/src/cyclone/parsers/parse_ta1.py:1-29` (the smallest parser — TA1 is just ISA + TA1 + IEA). The same skeleton scales to every other EDI type by adding `_consume_<segment>` helpers.
 ```python
 """Parse an X12 TA1 (Interchange Acknowledgment) file.
 Whole-document problems (missing ISA, no TA1) raise CycloneParseError.
 """
 from __future__ import annotations
 import logging
 from datetime import date
 from cyclone.parsers.exceptions import CycloneParseError
 from cyclone.parsers.models import BatchSummary, Envelope
 from cyclone.parsers.models_ta1 import ParseResultTa1, Ta1Ack
 from cyclone.parsers.segments import tokenize
 log = logging.getLogger(__name__)
 def _parse_yyyymmdd(s: str) -> date | None:
    """Parse an 8-digit CCYYMMDD string. Returns None on bad input."""
    ...
 def _build_envelope(segments: list[list[str]], input_file: str) -> Envelope:
    """Build the envelope from ISA. TA1 has no GS/ST — just ISA → TA1 → IEA."""
    ...
 def _consume_ta1(segments: list[list[str]], idx: int) -> tuple[Ta1Ack, int]:
    """Read a TA1 segment and return a Ta1Ack. Returns (model, next_idx)."""
    ...
 def parse_ta1_text(text: str, *, input_file: str = "") -> ParseResultTa1:
    """Parse a complete TA1 document and return a ParseResultTa1."""
    segments = tokenize(text)
    envelope = _build_envelope(segments, input_file=input_file)
    ta1_idx = next(
        (i for i, seg in enumerate(segments) if seg[0] == "TA1"), None,
    )
    if ta1_idx is None:
        raise CycloneParseError("No TA1 segment found")
    ta1, _ = _consume_ta1(segments, ta1_idx)
    ...
    return ParseResultTa1(envelope=envelope, ta1=ta1, summary=summary, ...)
 __all__ = ["parse_ta1_text"]
 ```
 The orchestrator pattern is the same in every parser: `tokenize` → `_build_envelope` → segment consumers in order → wrap into a `ParseResult<EDI>` model. The Pydantic result is what the API / store layer consumes.
 ### A validator rule — `_r<n>_<name>` registered in `_RULES`
 Taken from `backend/src/cyclone/parsers/validator.py:23-66` (the canonical R010–R100 block).
 ```python
 from collections.abc import Iterable
 from cyclone.parsers.models import ClaimOutput, ValidationIssue
 from cyclone.parsers.payer import PayerConfig
 NPI_RE = re.compile(r"^\d{10}$")
 Rule = Callable[[ClaimOutput, PayerConfig], Iterable[ValidationIssue]]
 def _r020_npi_format(claim: ClaimOutput, _: PayerConfig) -> Iterable[ValidationIssue]:
    if claim.billing_provider.npi and not NPI_RE.match(claim.billing_provider.npi):
        yield ValidationIssue(
            rule="R020_npi_format",
            severity="error",
            message=f"Billing provider NPI must be 10 digits, got {claim.billing_provider.npi!r}",
        )
 def _r021_npi_checksum(claim: ClaimOutput, _: PayerConfig) -> Iterable[ValidationIssue]:
    """SP20: validate the billing-provider NPI's Luhn check digit."""
    npi = claim.billing_provider.npi
    if not npi or not NPI_RE.match(npi):
        return  # R020 already flagged the format — skip silently.
    try:
        from cyclone.npi import is_valid_npi
    except ImportError:
        return
    if not is_valid_npi(npi):
        yield ValidationIssue(
            rule="R021_npi_checksum",
            severity="warning",
            message=f"Billing provider NPI {npi!r} fails Luhn checksum (likely typo)",
        )
 _RULES: list[Rule] = [
    _r010_clm01_present,
    _r011_total_charge_positive,
    _r020_npi_format,
    _r021_npi_checksum,
    # ... R030, R031, R032-R035, R050, R060, R070, R100, R200-R210
 ]
 ```
 For 835 rules, prefix the rule string with `R835_` (e.g. `R835_BPR01_handling_code_allowed`) and target the `ParseResult835` model instead of `ClaimOutput` — see `backend/src/cyclone/parsers/validator_835.py:38-79`.
 ### A test that uses a prodfiles fixture
 Taken from `backend/tests/test_api_999.py:53-72`. The autouse `conftest.py` already provides a per-test SQLite DB; most tests just add a `client` fixture and reference the fixture path as a module-level constant.
 ```python
 """Tests for the FastAPI surface in cyclone.api for the 999 endpoint."""
 from __future__ import annotations
 from pathlib import Path
 import pytest
 from fastapi.testclient import TestClient
 from cyclone.api import app
 # Fixture reference — flat, module-level Path constant. NEVER reach into
 # docs/prodfiles/ from a test; the fixtures/ dir is the test-consumed surface.
 ACCEPTED = Path(__file__).parent / "fixtures" / "minimal_999.txt"
 REJECTED = Path(__file__).parent / "fixtures" / "minimal_999_rejected.txt"
@pytest.fixture
 def client() -> TestClient:
    return TestClient(app)
 def test_parse_999_endpoint_happy_path(client: TestClient):
    text = ACCEPTED.read_text()
    resp = client.post(
        "/api/parse-999",
        files={"file": ("minimal_999.txt", text, "text/plain")},
        headers={"Accept": "application/json"},
    )
    assert resp.status_code == 200, resp.text
    body = resp.json()
    assert body["ack"]["ack_code"] == "A"
 ```
 For pure-unit parser tests (no API), the same path is reused — see `backend/tests/test_parse_837.py:8` (`FIXTURE = Path(__file__).parent / "fixtures" / "minimal_837p.txt"`).
 ## Anti-patterns
 - **Don't re-parse raw X12 strings inside validators.** Always parse first into the typed `ParseResult<EDI>` / `ClaimOutput`, then validate against that. Validators index into the model fields (or `claim.raw_segments` for spot-checks of specific segment presence) — they never call `tokenize` again. R034's `REF*G1` presence check (`validator.py:104-107`) is the only place that legitimately touches `raw_segments`, and it does so to confirm a single segment exists.
 - **Don't bake payer-specific logic into the generic parser.** Payer variations live in `backend/src/cyclone/parsers/payer.py` (`PayerConfig`, `PayerConfig835`) and `backend/src/cyclone/payers.py` (the YAML loader from `config/payers.yaml`). Parsers accept the config as an argument; rules read it from the `cfg` parameter. A new payer never requires a new parser file — extend the config and add / adjust an R-code rule.
 - **Don't add a validator rule without an R-code.** The `rule="R<n>_<name>"` string is the stable identifier the UI greys out, the API returns in `errors[].rule`, and tests assert against. Inventing a rule without an R-code (or reusing an R-code with new semantics) breaks the operator workflow. New SP-N increments reserve their R-code range up front (SP9 reserved R200–R210, SP20 added R021) and document it in the spec.
 ## Related skills
 - **`cyclone-store`** — load when the increment changes how a parsed `ClaimOutput` / `ParseResult<EDI>` is persisted (`store.py` write path, `<entity>_written` events).
 - **`cyclone-api-router`** — load when the increment adds or changes an HTTP endpoint that surfaces a parsed result (e.g. `/api/parse-999`, `/api/parse-837`, `/api/parse-835`).
 - **`cyclone-tests`** — every parser addition ships a fixture in `backend/tests/fixtures/` and a pytest case; load this skill for the fixture-drop-in and autouse-conftest rules.
 - **`cyclone-cli`** — load when the increment adds a CLI subcommand. The `cyclone parse-837 <file>` and `cyclone parse-835 <file>` smoke commands at `backend/src/cyclone/cli.py:77,151` are the parser-level smoke tests; the `validate-npi` and `validate-tax-id` commands exercise the format helpers.
 - **`cyclone-spec`** — load when the SP-N spec for the increment introduces a new R-code range or a new transaction type; the spec's `## Decisions` section is where the R-code reservation gets locked in.

 description: "Cyclone React page conventions (TanStack Query, use<X> hook, drawer, URL state, .test.tsx sibling, Layout / PageHeader / Sidebar). Use when: adding a new page, refactoring an existing one, or wiring a drawer into a page."

 # cyclone-frontend-page
 Cyclone pages live at `src/pages/<Name>.tsx`: a `use<X>` hook in `src/hooks/use<X>.ts` does the fetching (and optionally the live-tail subscription), `<Layout>` + `<PageHeader>` + `<Sidebar>` (`src/components/`) provide the app shell, and any right-side detail (claim, remittance) lives in `src/components/<DrawerName>/` whose open/close state is mirrored to the URL via `useDrawerUrlState`. This skill codifies the conventions so additions stay consistent with the eleven pages already shipped.
 As of this writing: **11 pages** under `src/pages/` (9 of 11 with a `*.test.tsx` sibling — Dashboard, Upload, and BatchDiff are not yet covered; be the first when you refactor them), **~30 hooks** under `src/hooks/`, and **2 drawer modules** at `src/components/{ClaimDrawer,RemitDrawer}/`. The next increment is **SP22**.
 ## When to use
 - **Adding a new page.** Mounting a new screen in `src/pages/` — you need the Layout + PageHeader + table shape, the `use<X>` hook split, and the route registration point in `src/App.tsx`.
 - **Refactoring an existing page.** Splitting a 600-line page, swapping a manual `fetch` for a hook, or moving in-component state into the URL — load this skill to confirm the destination shape.
 - **Wiring a drawer.** Adding a new right-side detail drawer (e.g. `BatchDrawer`, `ActivityDrawer`) — you need `useDrawerUrlState` for URL-driven open/close, the `src/components/<DrawerName>/` folder layout, and the deep-link contract so `?claim=…` / `?remit=…` round-trips.
 - **Sharing state via URL.** Persisting filter / page / drawer state across reloads — confirm the `useDrawerUrlState` / `useRemitDrawerUrlState` hook pair is the right tool before reaching for `useState` + history.
 ## Conventions
 1. **Page shape.** Every page in `src/pages/<Name>.tsx` exports a `function <Name>()` (most pages use a named export — see `src/pages/Claims.tsx:51`, `Remittances.tsx:62`, `Dashboard.tsx:68`; `src/pages/Inbox.tsx:40` is the lone default export). The app shell is provided by the `<Layout>` route wrapper in `src/App.tsx:30`. Each page sets a `<PageHeader>` (`src/components/PageHeader.tsx:18`) and renders a table, list, or KPI grid. Sidebar nav is mounted once by `<Layout>` at `src/components/Sidebar.tsx`.
 2. **Data hook.** Each page pairs with a `use<X>` hook in `src/hooks/use<X>.ts` (e.g. `Claims` ↔ `useClaims`, `Remittances` ↔ `useRemittances`, `Acks` ↔ `useAcks`). The hook returns `{ data, isLoading, isError, error, refetch }` from TanStack Query's `useQuery` (see `src/hooks/useClaims.ts:24-31`, `useRemittances.ts:21-25`). Pages never call `fetch` or `@/lib/api` directly — the hook is the boundary so the page is testable with `vi.mock("@/lib/api", ...)`.
 3. **Live tail.** Pages with live data compose three hooks in order: the `use<X>` initial fetch, `useTailStream(resource)` (`src/hooks/useTailStream.ts:80` — opens the NDJSON stream, drives the backoff/stall state machine), and `useMergedTail(resource, baseItems, filterFn?)` (`src/hooks/useMergedTail.ts:25` — merges snapshot + tail, dedup'd by id). The full wiring lives at `src/pages/Claims.tsx:85-89` and `Remittances.tsx:81-83`. The streaming subscription belongs on the page, not in the data hook — hoisting it couples the lifecycle to whoever mounts `use<X>`.
 4. **Drawer.** Right-side detail drawers live in `src/components/<DrawerName>/` (currently `ClaimDrawer/`, `RemitDrawer/`) with a barrel `index.ts` (`src/components/ClaimDrawer/index.ts:1-14`). The drawer is wired to URL state via `useDrawerUrlState()` for `?claim=…` (`src/hooks/useDrawerUrlState.ts`) or `useRemitDrawerUrlState()` for `?remit=…` (`src/hooks/useRemitDrawerUrlState.ts`). Open state is driven by the URL, not a `useState` flag, so deep-links round-trip.
 5. **Tests.** Every page gets a `src/pages/<Name>.test.tsx` sibling (e.g. `Claims.test.tsx`, `Remittances.test.tsx`, `Batches.test.tsx`). Every hook gets a `src/hooks/use<X>.test.ts` sibling (e.g. `useClaims.test.ts`, `useRemittances.test.ts`). The shared setup — `// @vitest-environment happy-dom`, `IS_REACT_ACT_ENVIRONMENT = true`, `QueryClient` provider, `vi.mock("@/lib/api", ...)` — is documented in `cyclone-tests`; mirror `src/pages/Claims.test.tsx:1-30` for the canonical page-test shape.
 6. **UI primitives.** Use Radix-backed components from `src/components/ui/` (`button.tsx`, `dialog.tsx`, `table.tsx`, `select.tsx`, `pagination.tsx`, `empty-state.tsx`, `error-state.tsx`, `filter-chips.tsx`, `skeleton.tsx`, `input.tsx`, `label.tsx`, `card.tsx`, `badge.tsx`, `skip-link.tsx`, `claim-state-badge.tsx`). Don't pull in a new UI library without discussion — every primitive here is already consumed by at least one shipped page.
 7. **Routing.** Pages register their route in `src/App.tsx` as a `<Route path="<name>" element={<<Name>> />} />` inside the `<Layout>` element wrapper (`src/App.tsx:30-44`). Currently every page is a static import; switch to `React.lazy(() => import(...))` only if a page grows heavy (large parse/EDI libs, chart code) and the import cost shows up in the bundle report.
 ## Patterns
 ### `Claims.tsx`-style page (Layout + PageHeader + table + drawer)
 Canonical page shape — composes the data hook, the tail triplet, and
 `useDrawerUrlState` for the `?claim=…` deep-link. See
 `src/pages/Claims.tsx:51-200` for the full file.
 ```tsx
 import { useMemo, useState } from "react";
 import { Table, TableBody, TableRow, /* … */ } from "@/components/ui/table";
 import { PageHeader } from "@/components/PageHeader";
 import { ClaimDrawer } from "@/components/ClaimDrawer";
 import { useClaims } from "@/hooks/useClaims";
 import { useDrawerUrlState } from "@/hooks/useDrawerUrlState";
 import { useTailStream } from "@/hooks/useTailStream";
 import { useMergedTail } from "@/hooks/useMergedTail";
 import { TailStatusPill } from "@/components/TailStatusPill";
 export function Claims() {
  const [status, setStatus] = useState<ClaimStatus | null>(null);
  const params = useMemo(() => ({ status, limit: 25, offset: 0 }), [status]);
  const { data } = useClaims(params);
  const { status: tailStatus, lastEventAt, forceReconnect } = useTailStream("claims");
  const items = useMergedTail("claims", data?.items ?? [], (c) => !status || c.status === status);
  const { claimId, openClaim, closeClaim } = useDrawerUrlState();
  return (
    <>
      <PageHeader
        eyebrow="Inbox"
        title="Claims"
        status={<TailStatusPill status={tailStatus} lastEventAt={lastEventAt} onReconnect={forceReconnect} />}
      />
      <Table>
        <TableBody>
          {items.map((c) => (
            <TableRow key={c.id} onClick={() => openClaim(c.id)}>{/* …cells… */}</TableRow>
          ))}
        </TableBody>
      </Table>
      <ClaimDrawer claimId={claimId} claims={items} onClose={closeClaim} onNavigate={openClaim} />
    </>
  );
 }
 ```
 ### `use<X>` data hook (TanStack Query)
 Pattern from `src/hooks/useClaims.ts:24-67` and `useRemittances.ts:21-65`.
 Returns a stable shape so the page treats all data hooks uniformly.
 The tail subscription lives on the page (see Convention 3), not here.
 ```ts
 import { useQuery } from "@tanstack/react-query";
 import { api, type ListClaimsParams, type PaginatedResponse } from "@/lib/api";
 import type { Claim } from "@/types";
 export function useClaims(params: ListClaimsParams) {
  return useQuery<PaginatedResponse<Claim>>({
    queryKey: ["claims", params],
    queryFn: () => api.listClaims<Claim>(params),
    enabled: api.isConfigured,
    // …in-memory fallback when !api.isConfigured…
  });
 }
 ```
 ### Drawer component with `useDrawerUrlState`
 Pattern from `src/components/ClaimDrawer/ClaimDrawer.tsx:1-50` +
 `src/hooks/useDrawerUrlState.ts`. The drawer takes `claimId` as a
 prop (driven by the URL), renders nothing when `null`, and uses
 `useDrawerKeyboard` for j/k navigation + Escape to close. The page
 that mounts it controls the URL — `openClaim("abc")` sets `?claim=abc`,
 removing the param closes the drawer, and reload preserves the state.
 ```tsx
 import { Dialog, DialogContent } from "@/components/ui/dialog";
 import { useClaimDetail } from "@/hooks/useClaimDetail";
 import { useDrawerKeyboard } from "@/hooks/useDrawerKeyboard";
 export function ClaimDrawer({ claimId, claims, onClose, onNavigate, onToggleHelp }) {
  const open = claimId !== null;
  const { data, isLoading, isError, error } = useClaimDetail(claimId);
  useDrawerKeyboard({ open, claims, onClose, onNavigate, onToggleHelp });
  if (!open) return null;
  return (
    <Dialog open onOpenChange={(o) => !o && onClose()}>
      <DialogContent>{/* header + body panels from useClaimDetail… */}</DialogContent>
    </Dialog>
  );
 }
 ```
 ## Anti-patterns
 - **Don't `fetch` from inside a page component.** All API access goes through the `use<X>` hook in `src/hooks/use<X>.ts`. Pages that reach for `fetch(...)` directly can't be tested with `vi.mock("@/lib/api", ...)` and split the data lifecycle across files. The hook returns `{ data, isLoading, isError, error, refetch }` so the page is a pure renderer.
 - **Don't open a drawer via local component state.** A `const [open, setOpen] = useState(false)` for a drawer breaks deep-links and reload-restore. Use `useDrawerUrlState()` (claim) or `useRemitDrawerUrlState()` (remit) so the URL is the single source of truth.
 - **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/` (e.g. `src/lib/format.ts` for currency / date formatting). JSX is for layout; mixing in `items.filter(...).sort(...)` inline is hard to test and hides behavior from the hook.
 - **Don't call `useTailStream` from inside a `use<X>` hook.** The streaming subscription belongs on the page (see `src/pages/Claims.tsx:85-89`). Hoisting it into `useClaims` couples the open/close lifecycle of the page to whoever mounts the hook, and breaks the one-resource-one-page ownership that the backoff/stall state machine assumes.
 - **Don't import a new UI library to render a button, modal, or table.** Radix-backed primitives in `src/components/ui/` already cover every widget the shipped pages use. Reach for a new library only after the primitive gap is real and the proposal is in a spec / PR.

 description: "Cyclone SP-N superpowers increment flow — spec → plan → implement → merge. Use when: starting a new numbered feature increment, naming a branch, opening a SP-N PR, or doing the merge dance into main."
 ---
 # cyclone-spec
 The Cyclone repo ships every new feature as a numbered **SP-N increment**:
 a spec, a plan, an implementation branch, and a single atomic merge commit
 into `main`. This skill encodes the conventions so every increment follows
 the same shape and the commit history stays auditable.
 As of this writing: **16 specs** in `docs/superpowers/specs/`, **12 plans**
 in `docs/superpowers/plans/`, and SP numbers used through **SP21** (the
 universal-drilldown design in progress). The next increment is **SP22**.
 ## When to use
 - **Starting a new feature increment.** You are about to add a numbered
  feature, fix that crosses subsystem boundaries, or anything bigger than
  a one-line change. Before you write code, reserve the next SP number and
  write the spec.
 - **Naming the spec / plan files or the branch.** You have a topic, a
  date, and a number — and you need the exact path / branch shape so
  existing scripts and reviewers can find the artifacts.
 - **Opening the SP-N PR.** You are about to push the branch and need the
  PR title format and the commit-prefix conventions so the merge commit
  reads cleanly.
 - **Doing the merge dance.** Review is approved and you're about to land
  the branch into `main`. Use this skill to confirm the merge shape — no
  squash, no rebase, one atomic merge commit.
 ## Conventions
 1. **Numbering.** Reserve the next SP-N number — the next integer after
   the highest `SP<n>` already used in `git log`. Never reuse a number,
   even after deletion. Numbering is monotonic and lives in the merge
   history.
 2. **Branch.** `sp<N>-<short-kebab-topic>` — e.g. `sp22-line-reconciliation`,
   `sp9-multi-payer-npi`. Kebab-case, lowercase, no spaces, no slashes.
   The branch name is the canonical handle for the increment.
 3. **Spec path.** `docs/superpowers/specs/YYYY-MM-DD-cyclone-<topic>-design.md`
   with header `Status: Draft, pending user review`. One spec per
   increment. Real examples: `2026-06-19-cyclone-db-reconciliation-design.md`
   (SP3), `2026-06-20-cyclone-multi-payer-npi-sftp-design.md` (SP9).
 4. **Plan path.** `docs/superpowers/plans/YYYY-MM-DD-cyclone-<topic>.md`.
   Header per the upstream `superpowers:writing-plans` skill: a
   `For agentic workers:` line that names
   `superpowers:subagent-driven-development` or
   `superpowers:executing-plans`, plus a `Goal / Architecture / Tech
   Stack / Spec` metadata block, then numbered tasks with
   `- [ ] Step N:` checkboxes.
 5. **Commit prefix.** All commits on the branch follow these prefixes —
   they make the SP-N merge commit readable and let `git log --grep`
   filter cleanly:
   - `feat(sp<N>): …` — implementation commits (e.g. `feat(sp20): NPI Luhn checksum + Tax ID format validation`).
   - `docs(spec): …` — landing the spec (e.g. `docs(spec): design for CycloneStore split (Step 4)`).
   - `docs(plan): …` — landing the plan.
   - `merge: SP<N> <topic> into main` — the merge commit itself (e.g. `merge: SP14 5-lane Inbox UI + acknowledge action into main`).
 6. **PR title.** `SP<N> <Topic>` — e.g. `SP22 Line reconciliation`.
   Matches the merge-commit subject so GitHub's "merged PR" view and the
   `git log` entry are identical strings.
 7. **Merge shape.** A single atomic merge commit into `main` after
   review. **No squash** — squash collapses the per-commit history and
   breaks the SP-N audit trail. **No rebase** — rebase rewrites the SHAs
   the PR review was performed against. The SP-N merge commit *is* the
   record of the increment landing.
 ## Patterns
 ### Spec header (canonical SP-N shape, post-SP9)
 This is the canonical header for new specs. Older specs (pre-SP9) deviate
 slightly — different title style, no Branch or Aesthetic direction line —
 and have not been retroactively normalized. **Use this template for any
 new SP-N spec.**
 ```markdown
 # Sub-project <N> — <Topic>: Design Spec
 **Date:** YYYY-MM-DD
 **Status:** Draft, awaiting user sign-off
 **Branch:** `sp<N>-<short-kebab-topic>`
 **Aesthetic direction:** <one line — e.g. "No new UI" or "Modern (geometric sans + bold borders + electric blue accent)">
 ## 1. Scope
 <2-6 lines: what's in, what's out, with explicit out-of-scope list>
 ```
 Worked example (matches this template): `docs/superpowers/specs/2026-06-20-cyclone-multi-payer-npi-sftp-design.md`.
 ### Plan header (every SP-N plan starts with this)
 ```markdown
 # <Topic> Implementation Plan
 > **For agentic workers:** REQUIRED SUB-SKILL: Use
 > superpowers:subagent-driven-development (recommended) or
 > superpowers:executing-plans to implement this plan task-by-task. Steps
 > use checkbox (`- [ ]`) syntax for tracking.
 **Goal:** <one sentence — the outcome>
 **Architecture:** <one paragraph — how it's structured>
 **Tech Stack:** <comma-separated list>
 **Spec:** [`docs/superpowers/specs/YYYY-MM-DD-cyclone-<topic>-design.md`](../specs/...)
 ---
 ## File structure
 <tree of new / modified files>
 ## Task 0: <setup>
 ## Task 1: <first user-visible step>
 …
 ```
 Real examples: `docs/superpowers/plans/2026-06-21-cyclone-skill-catalog.md`,
 `docs/superpowers/plans/2026-06-21-cyclone-store-split.md`.
 ## Anti-patterns
 - **Don't skip the spec ("it's a small fix").** Small fixes still get a
  3-line spec when they introduce a new numbered increment. The spec is
  the *what* and the audit trail; the plan is the *how*. Without a spec
  the merge commit has no anchor.
 - **Don't squash the merge commit.** The SP-N merge commit is the audit
  trail — it tells future you exactly which feature landed and which
  commits composed it. Squash collapses that into one opaque commit and
  the per-commit history is lost.
 - **Don't put code in the spec — the spec is the *what*, the plan is the
  *how*.** Specs describe scope, goals, non-goals, and decisions. Code
  snippets belong in the plan (with checkbox steps) or in the diff, not
  in the spec. SP-N specs in this repo routinely have **zero** code
  blocks.
 ## Related skills
 - **`cyclone-tests`** — every spec lists test impact; load this when
  drafting or reviewing the spec to confirm fixture / `.test.tsx`
  implications.
 - **`cyclone-edi`** — load when the SP-N increment touches an EDI parser,
  validator rule, or CAS mapping.
 - **`cyclone-tail`** — load when the increment changes the live-tail wire
  format or adds a streaming page.
 - **`cyclone-store`** — load when the increment adds a write-path,
  touches `store.py`, or wires a new `<entity>_written` event.
 - **`cyclone-api-router`** — load when the increment adds or changes an
  HTTP endpoint in `api_routers/`.
 - **`cyclone-frontend-page`** — load when the increment adds or
  refactors a page in `src/pages/`.
 - **`cyclone-cli`** — load when the increment adds a CLI subcommand or
  changes exit codes.
 - **`superpowers:brainstorming`** (global) — run before the spec to lock
  the scope / decisions in the spec's `## Decisions (locked during
  brainstorming)` section.
 - **`superpowers:writing-plans`** (global) — produces the plan header
  format every SP-N plan follows.

 description: "Cyclone store write-paths, the pubsub event contract (claim_written / remittance_written / activity_recorded), and the SP21 store-split boundary map. Use when: touching store.py, adding a new entity, wiring a new write event, or splitting a store module."
 ---
 # cyclone-store
 Cyclone persists every parsed X12 batch through one facade,
 `CycloneStore` (`backend/src/cyclone/store.py:882`). Every write
 inserts the row AND publishes a pubsub event on the in-process
 `EventBus` (`backend/src/cyclone/pubsub.py:20`) so live-tail pages
 see new rows the moment they land. The event contract is the seam
 between persistence and streaming — a wrong event name silently
 goes stale.
 As of this writing: the store is a **single 2412-line module** and
 the SP21 split into `backend/src/cyclone/store/` is in progress.
 Three event kinds: `claim_written`, `remittance_written`,
 `activity_recorded`. Next: **SP22**.
 ## When to use
 - **Adding a new entity.** You need a new ORM model + write method +
  event kind + snapshot serializer and want to know where each piece
  lives (current monolith vs. post-SP21 module).
 - **Wiring a new write event.** You're adding a `<entity>_written`
  event and need both the publish call in the store AND the
  subscribe call in the live-tail endpoint to stay in sync.
 - **Debugging a write-path issue.** A page isn't reflecting new
  rows, the DB has the row but the stream is silent, or the publish
  raises and rolls back the transaction.
 - **Splitting a store module.** You're moving a domain out of
  `store.py` into its own module under `backend/src/cyclone/store/`
  and need the SP21 module list + facade re-export rules.
 ## Conventions
 1. **All writes go through `CycloneStore`.** Route handlers and
   parsers must not write directly to the ORM session. The facade
   opens a short-lived session via `db.SessionLocal()()`. Direct ORM
   access is the #1 way the live-tail contract gets bypassed (no
   event published → page silently goes stale). Read paths are
   similar — prefer the facade's `iter_*` / `get_*` methods over raw
   `s.execute(select(...))`.
 2. **Every write publishes an event.** The event name matches the
   entity: `claim_written`, `remittance_written`,
   `activity_recorded` (the trailing `_recorded` signals a
   non-canonical row — activity events are derived, not first-class;
   current names at `store.py:1072,1081,1096`). New entities get
   `<entity>_written`; activity-style side rows get
   `<entity>_recorded`. Publish is **best-effort** — failures are
   logged but never roll back the persisted batch
   (`store.py:1097-1098`).
 3. **Snapshot shape.** Each entity has a `to_ui_<entity>` serializer
   (plain Python function returning a dict) — currently
   `to_ui_claim`, `to_ui_remittance`, `to_ui_claim_from_orm`,
   `to_ui_remittance_from_orm`, `to_ui_provider`. Post-SP21 these
   move to `backend/src/cyclone/store/ui.py`. The serializer is the
   single source of truth for what the frontend sees — every event
   payload MUST match what the matching list endpoint returns for
   that row (`store.py:1052-1054`).
 4. **SP21 boundaries.** Post-split, each domain lives in its own
   module under `backend/src/cyclone/store/`: `__init__.py` (facade
   + `CycloneStore` class), `exceptions.py`, `records.py`,
   `orm_builders.py`, `ui.py`, `write.py`, `batches.py`,
   `claim_detail.py`, `acks.py`, `backups.py`, `inbox.py`,
   `providers.py`. Cross-module writes go through `CycloneStore`
   facade methods, not direct module access. The facade re-exports
   every name callers currently import from `cyclone.store`. Full
   list: `docs/superpowers/plans/2026-06-21-cyclone-store-split.md:25-37`.
 5. **No business logic in route handlers.** A route handler validates
   input, calls `store.<method>(...)`, passes the `event_bus`,
   returns the serialized result. Reconciliation, idempotency
   checks, CAS adjustment persistence — all live in the store.
 ## Patterns
 ### A `CycloneStore.add` write — publishes events from inserted rows
 Taken from `backend/src/cyclone/store.py:898-1107`. The method opens
 a session, inserts rows, then runs a sync `_publish_events_sync`
 after commit so subscribers can immediately re-fetch consistent data.
 ```python
 def add(
    self,
    record: BatchRecord,
    *,
    event_bus: "EventBus | None" = None,
 ) -> None:
    inserted_claim_ids: list[str] = []
    with db.SessionLocal()() as s:
        s.add(Batch(id=record.id, kind=record.kind, ...))
        if isinstance(record, BatchRecord837):
            for claim in record.result.claims:
                if s.get(Claim, claim.claim_id) is not None:
                    continue                       # idempotency: skip dupes
                s.add(_claim_837_row(claim, record.id))
                s.add(ActivityEvent(kind="claim_submitted", ...))
                inserted_claim_ids.append(claim.claim_id)
        # ... 835 branch + flush + cas adjustments ...
        s.commit()
    if event_bus is not None and inserted_claim_ids:
        self._publish_events_sync(event_bus, record, inserted_claim_ids)
 def _publish_events_sync(self, event_bus, record, claim_ids):
    with db.SessionLocal()() as s:
        for cid in claim_ids:
            ui = to_ui_claim_from_orm(s.get(Claim, cid), ...)
            self._sync_publish(event_bus, "claim_written", ui)
        # ... remittance + activity loops ...
 ```
 `EventBus.publish` is async but the body is pure sync `put_nowait`,
 so the store calls `_sync_publish` directly to avoid forcing sync
 FastAPI handlers to await.
 ### Backend `/api/<resource>/stream` endpoint — subscribes to the event
 Taken from `backend/src/cyclone/api.py:1380-1401`. Two phases — eager
 snapshot, then live subscription — wrapped in `StreamingResponse`
 with `media_type="application/x-ndjson"`.
 ```python
@app.get("/api/claims/stream")
 async def claims_stream(request: Request, ...) -> StreamingResponse:
    bus: EventBus = request.app.state.event_bus
    async def gen() -> AsyncIterator[bytes]:
        rows = store.iter_claims(status=status, ...)         # 1. Snapshot
        for row in rows:
            yield _ndjson_line({"type": "item", "data": row})
        yield _ndjson_line({"type": "snapshot_end", "data": {"count": len(rows)}})
        async for chunk in _tail_events(request, bus, ["claim_written"]):  # 2. Live
            yield chunk
    return StreamingResponse(gen(), media_type="application/x-ndjson")
 ```
 `_ndjson_line` and `_tail_events` live in
 `backend/src/cyclone/api_helpers.py`. The `["remittance_written"]`
 and `["activity_recorded"]` subscriptions are at `api.py:1891,2002`.
 ### Backend test — asserts both the row AND the event landed
 The autouse `conftest.py` (`backend/tests/conftest.py:20`) wires a
 fresh `EventBus` onto `app.state` per test.
 ```python
 def test_publishes_claim_written_event(client: TestClient) -> None:
    bus = app.state.event_bus
    resp = client.post("/api/parse-837",
                       files={"file": ("x.837", MINIMAL_837, "text/plain")})
    assert resp.status_code == 200
    assert list(store.iter_claims(limit=10))             # row landed
    queues = bus._subscribers.get("claim_written", [])    # event published
    assert queues
    evt = queues[0].get_nowait()
    assert evt["_kind"] == "claim_written"
 ```
 ## Anti-patterns
 - **Don't read directly from the ORM in a route handler — go through
  the snapshot serializer.** A handler that does
  `with db.SessionLocal()() as s: row = s.get(Claim, cid); return row`
  bypasses `to_ui_claim_from_orm` and silently drifts from the event
  payload shape. Always call `store.get_claim_detail(cid)` (or the
  equivalent `get_*` facade method).
 - **Don't introduce a new event name without updating the subscriber
  list.** Today every `<entity>_written` event has exactly one
  consumer — the matching `/api/<resource>/stream` endpoint,
  currently in `backend/src/cyclone/api.py` (claims at `:1398`,
  remittances at `:1891`, activity at `:2002`). Any future split
  into `backend/src/cyclone/api_routers/` must wire the same
  subscription.
 - **Don't merge a write method with its event publication into
  separate places.** `_publish_events_sync` lives next to `add` in
  `store.py:1042-1107` so reviewers see both halves of the contract
  in one diff. Post-SP21 the same rule applies.
 - **Don't make the publish call blocking on commit failures.**
  Publish errors are caught and logged at `store.py:1097-1098`; a
  failing subscriber MUST NOT roll back the persisted batch. The
  batch is the source of truth; the event is the cache-invalidation
  hint.
 ## Related skills
 - **`cyclone-edi`** — the parsed `ClaimOutput` / `ParseResult<EDI>`
  lands in the store via `CycloneStore.add`.
 - **`cyclone-api-router`** — the route that calls `store.<method>(...)`
  and (for stream endpoints) subscribes to the matching
  `<entity>_written` event.
 - **`cyclone-tail`** — the consumer side of the event contract;
  load when changing the wire format or adding a streaming hook.
 - **`cyclone-tests`** — write-path tests live under `backend/tests/`
  and assert both the DB row and the event payload.

 description: "Cyclone live-tail streaming wire format and the useTailStream / useMergedTail hook triplet. Use when: adding a new streaming list page, changing the wire format, debugging stalled/reconnecting state, or modifying the StatusPill behavior."
 ---
 # cyclone-tail
 Cyclone keeps the Claims, Remittances, and Activity pages live without
 polling: every store write publishes an internal EventBus event, the
 page opens a `GET /api/<resource>/stream` HTTP/1.1 chunked-NDJSON
 connection, and new rows land in the table the moment they hit the
 database. This skill codifies the wire format, the hook triplet, and
 the backoff/stall machinery so additions stay consistent with the
 three streaming pages already shipped (`Claims`, `Remittances`,
 `ActivityLog`).
 ## When to use
 - **Adding a new streaming page.** Mounting `useTailStream(resource)`
  on a page — you need the hook triplet shape (initial fetch +
  `useTailStream` + `useMergedTail`), the `<TailStatusPill>` wiring,
  and the dedup rules in `useMergedTail`.
 - **Changing the wire format.** Adding a new event type — update
  `TailEvent` in `src/lib/tail-stream.ts:22-44`, the dispatch switch
  in `src/hooks/useTailStream.ts:173-195`, the emitter in
  `backend/src/cyclone/api_helpers.py:tail_events()`, and
  `references/wire-format.md`.
 - **Debugging stalled/reconnecting state.** Confirm whether the
  backend is heartbeating (`CYCLONE_TAIL_HEARTBEAT_S`, default `15s`)
  or the stall timer fired (`STALL_TIMEOUT_MS = 30_000` at
  `src/hooks/useTailStream.ts:53`).
 - **Tuning heartbeat/stall timing.** Changing the 30s stall threshold
  or the 15s heartbeat interval — README's "Status pill" + "Knobs"
  tables need to stay in sync (`README.md:109-129`).
 ## Conventions
 1. **Wire format.** Newline-delimited JSON. Every line is
   `{"type": ..., "data": ...}`. Known `type` values: `item`
   (per-row envelope), `snapshot_end` (`{"count": N}` marker after the
   snapshot), `heartbeat` (`{"ts": "<iso-8601>"}` keep-alive),
   `item_dropped` (`{"id": "..."}` queue-overflow notice), `error`
   (`{"message": "..."}` promoted to a thrown error by the hook).
   Defined at `src/lib/tail-stream.ts:22-44`; emitted by
   `backend/src/cyclone/api.py:1357-2006`. See
   `references/wire-format.md`.
 2. **Hook triplet.** Streaming pages compose three pieces:
   `useTailStream(resource)` (`src/hooks/useTailStream.ts:80` — opens
   the stream, drives the backoff/stall state machine, dispatches
   `item` events into `useTailStore`),
   `useMergedTail(resource, baseItems, filterFn?)`
   (`src/hooks/useMergedTail.ts:25` — returns
   `baseItems + tailSlice` dedup'd against `baseItems`), and a
   per-resource initial-fetch hook (`useClaims`, `useRemittances`,
   `useActivity`). The page wires all three — see
   `src/pages/Claims.tsx:87-89`.
 3. **Stall threshold.** 30 seconds of total silence — heartbeats
   included — flips status to `stalled` and surfaces the
   `↻ Reconnect` button on `<TailStatusPill>`. Constant:
   `STALL_TIMEOUT_MS = 30_000` at `src/hooks/useTailStream.ts:53`.
   Re-armed on every event including `heartbeat` and `item_dropped`
   (`useTailStream.ts:124-140`). Don't change without updating
   `README.md:109-123`.
 4. **Snapshot first.** Every stream emits the snapshot before any
   live `item` events, then closes with exactly one `snapshot_end`
   carrying `{"count": N}`. The hook uses `snapshot_end` to flip
   `<TailStatusPill>` from `connecting` to `live` and to reset the
   reconnect backoff counter (`useTailStream.ts:174-180`).
 5. **Content-Type.** Stream endpoints respond with
   `media_type="application/x-ndjson"` — see
   `backend/src/cyclone/api.py:1401,1894,2005`. Frontend sets
   `Accept: application/x-ndjson` at `src/lib/tail-stream.ts:67-70`.
   Never `application/json` for a stream endpoint.
 6. **Backoff.** Transient errors retry with `1s → 2s → 4s → 8s → 16s
   → 30s` capped — `BACKOFF_STEPS_MS` at
   `src/hooks/useTailStream.ts:48-50`. Counter resets on every
   `snapshot_end`.
 7. **Heartbeat knob.** Idle heartbeat interval is configurable via
   `CYCLONE_TAIL_HEARTBEAT_S` (default `15`, parsed at call time in
   `backend/src/cyclone/api_helpers.py:185-198`). Tests override to
   a small value to keep runtime bounded.
 ## Patterns
 ### Page-hook skeleton — `Claims.tsx`
 Pattern from `src/pages/Claims.tsx:85-90`. Three hooks in order:
 `useClaims(params)` (initial TanStack Query fetch),
 `useTailStream("claims")` (opens the stream, owns status state), and
 `useMergedTail("claims", data?.items ?? [], tailFilterFn)` (combines
 initial snapshot with live tail, dedup'd by id, filtered by the page's
 predicate applied AFTER dedup at `useMergedTail.ts:72-74`).
 ```ts
 import { useClaims } from "@/hooks/useClaims";
 import { useTailStream } from "@/hooks/useTailStream";
 import { useMergedTail } from "@/hooks/useMergedTail";

 ### Backend `/api/foo/stream` endpoint
 Pattern from `backend/src/cyclone/api.py:1357-1401`. Register BEFORE
 `/api/foo/{foo_id}` so the literal `stream` segment doesn't match as
 an id. Two phases — eager snapshot, then live subscription — wrapped
 in `StreamingResponse` with `media_type="application/x-ndjson"`.
 ```python
@app.get("/api/foo/stream")
 async def foo_stream(
    request: Request,
    status: str | None = Query(None),
    limit: int = Query(100, ge=1, le=1000),
 ) -> StreamingResponse:
    bus: EventBus = request.app.state.event_bus
    async def gen() -> AsyncIterator[bytes]:
        # 1. Snapshot.
        rows = store.iter_foos(status=status, limit=limit)
        for row in rows:
            yield _ndjson_line({"type": "item", "data": row})
        yield _ndjson_line({"type": "snapshot_end", "data": {"count": len(rows)}})
        # 2. Live subscription + heartbeats.
        async for chunk in _tail_events(request, bus, ["foo_written"]):
            yield chunk
    return StreamingResponse(gen(), media_type="application/x-ndjson")
 ```
 `_ndjson_line` and `_tail_events` live in
 `backend/src/cyclone/api_helpers.py`; the latter forwards EventBus
 events as `item` lines and emits `heartbeat` lines on the cadence
 from `heartbeat_seconds()`.
 ### `<TailStatusPill>` wiring
 Pattern from `src/components/TailStatusPill.tsx:22-83`. The pill
 takes `status` + `lastEventAt` from `useTailStream` plus
 `forceReconnect` so the `↻ Reconnect` button wires to the hook's
 `reconnectNonce` bump (aborts and reopens the stream —
 `useTailStream.ts:99-101`). The button only renders when
 `status === "stalled" || status === "error"` (`TailStatusPill.tsx:52`).
 ## Anti-patterns
 - **Don't hand-roll `fetch` + `ReadableStream` parsing in a page.**
  All stream consumers go through `streamTail(resource, opts?)` at
  `src/lib/tail-stream.ts:58`. The parser handles `TextDecoderStream`,
  newline splitting, malformed-line tolerance (`console.warn` + skip),
  the `KNOWN_TYPES` allowlist, and abort-on-signal semantics
  (`tail-stream.ts:75,98,107`). Duplicating it loses all of those.
 - **Don't change the wire format on one endpoint without updating
  the others.** The parser (`src/lib/tail-stream.ts`) and the hook
  dispatch switch (`useTailStream.ts:173-195`) are shared across all
  three live streams. Adding a new event type means updating
  `TailEvent`, `KNOWN_TYPES`, the dispatch `case`, the `armStall`
  re-arm list, and the backend emitter — in that order.
 - **Don't emit `item` events before `snapshot_end`.** The hook uses
  `snapshot_end` as the marker to flip `<TailStatusPill>` from
  `connecting` to `live` and to reset the reconnect backoff counter.
  Emitting `item`s first lands rows in `useTailStore` but the UI
  still reads "Connecting" — operators see a flash of stale state.
  Emit snapshot, then `snapshot_end`, then live (`api.py:1386-1401`).
 - **Don't change the 30s stall threshold without updating the README
  "Status pill" table.** The constant
  (`STALL_TIMEOUT_MS = 30_000` at `useTailStream.ts:53`) is the
  contract the pill is documented against — a bump needs the matching
  edit at `README.md:118`.
 - **Don't add `useTailStream` calls from `useFoo.ts` hooks.**
  Streaming connections belong on the page (`src/pages/Claims.tsx`,
  `Remittances.tsx`, `ActivityLog.tsx`). Hoisting into `useFoo`
  couples the lifecycle to whoever mounts it and breaks
  one-resource-one-page ownership.

 # Live-tail wire format — field reference
 The Cyclone live-tail NDJSON contract is owned by the frontend parser
 (`src/lib/tail-stream.ts:22-44`) and the backend emitter
 (`backend/src/cyclone/api_helpers.py:tail_events()` + the three
 endpoints in `backend/src/cyclone/api.py:1357-2006`). This file is the
 quick reference; the canonical prose lives in the README and the
 source-of-truth type definitions.
 ## Source
 Wire format excerpt copied verbatim from `README.md:76-94` (the
 "Live updates → Wire format" section). The README is the user-facing
 exposition; this reference adds the per-line field semantics and the
 parser-tolerance rules from the code.
 > Each stream endpoint emits newline-delimited JSON. The first batch
 > is the **snapshot** of currently-known rows; after that comes
 > **`snapshot_end`** with the count, then the **live** events.

 > {"type":"heartbeat","data":{"ts":"2026-06-20T23:17:09Z"}}   ← idle keep-alive
 > ```
 >
 > Lines are `{"type": ..., "data": ...}`; known types are `item`,
 > `snapshot_end`, `heartbeat`, and (rare) `item_dropped` /
 > `error`. Heartbeats keep the connection alive when nothing is
 > happening — clients flip to `stalled` after 30s of total silence
 > (heartbeat or otherwise) and surface a **↻ Reconnect** button.

 | `item`         | resource-specific row (`Claim` / `Remittance` / `Activity`) | yes, in `data` (the per-row envelope) | snapshot loop + `_tail_events` forwarding `claim_written` / `remittance_written` / `activity_recorded` | `dispatch(resource, ev.data)` → `useTailStore.addClaim` / `addRemittance` / `addActivity` (first-write-wins dedup on the id-keyed slices — `tail-store.ts:104,120`). |
 | `snapshot_end` | `{"count": N}` (integer ≥ 0)              | yes, on every stream                       | `api.py:1395,1889,1999` (one per stream, after the snapshot loop) | Flips `<TailStatusPill>` from `connecting` to `live`, resets the reconnect backoff counter to 0 (`useTailStream.ts:174-180`). |
 | `heartbeat`    | `{"ts": "<iso-8601 UTC>"}`                | yes, but only when idle                    | `_tail_events` in `api_helpers.py:241-245` (cadence from `heartbeat_seconds()`, default 15s) | Re-arms the stall timer (`useTailStream.ts:124-140`); no state change. |
 | `item_dropped` | `{"id": "<string>"}`                      | optional (rare; queue overflow)            | EventBus drop-oldest path (per the spec at `docs/superpowers/specs/2026-06-20-cyclone-live-tail-design.md:299`) | Re-arms the stall timer; no state change. The `id` field is informational — the hook does not refetch on drop, the page does (see Spec §3.6). |
 | `error`        | `{"message": "<string>"}`                 | optional (server-side failure)            | Reserved for future server-emitted errors (currently only thrown client-side) | Hook promotes to a thrown `Error(message)` so the catch block runs the reconnect machinery (`useTailStream.ts:190-194`). |
 ## Parser tolerance
 The shared parser at `src/lib/tail-stream.ts` is intentionally
 forgiving so a single bad frame doesn't kill the stream:
 - **Trailing `\r`** is stripped per line (`tail-stream.ts:116`) so a
  CRLF-terminated stream still parses.
 - **Malformed JSON** (`JSON.parse` throws) → `console.warn` + skip the
  line; the iterator continues (`tail-stream.ts:122-131`).
 - **Unknown `type`** (not in `KNOWN_TYPES`) → `console.warn` + skip
  (`tail-stream.ts:141-148`). Adding a new event type is
  forward-compatible: old clients see warn lines, new clients see the
  typed event.
 - **Empty lines** (consecutive `\n`s) → silently skipped
  (`tail-stream.ts:118`).
 - **No trailing newline** → flushed as a final partial line on
  stream close (`tail-stream.ts:154-178`).
 - **Abort signal** → iterator exits cleanly without throwing
  (`tail-stream.ts:75,98,107`).

 # cyclone-tests
 The Cyclone test suite is split two ways: **backend pytest** (89 test files under `backend/tests/`, 13 flat fixtures in `backend/tests/fixtures/`, one autouse `conftest.py` that resets the DB per-test) and **frontend vitest** (59 `*.test.ts(x)` siblings across `src/`, two rendering styles — `@testing-library/react` and a custom `createRoot`+`Probe` shim). This skill codifies the conventions so additions stay consistent with what's already there.
 As of this writing: **89 backend test files**, **13 flat backend fixtures**, **59 frontend `*.test.ts(x)` siblings**, and **23 prodfiles samples** across `docs/prodfiles/{837p-from-axiscare,835fromco,FromHPE,claims}/`. The next increment is **SP22**.
 ## When to use
 - **Adding a backend pytest case.** You're about to add a new `test_*.py` under `backend/tests/` and need the autouse DB-fixture rules, the fixture-path convention, and the right naming flavor (`test_api_*.py` vs `test_<module>_*.py`).
 - **Adding a frontend vitest test.** You're about to add a `*.test.ts(x)` sibling and need the `// @vitest-environment happy-dom` setup, the act-environment flag, and the right rendering helper (`@testing-library/react` vs the `createRoot`+`Probe` shim).
 - **Dropping in a prodfiles fixture.** You have a real EDI sample under `docs/prodfiles/<source>/` and need the copy step that makes it test-runnable without coupling the test to the prodfiles archive.
 - **Debugging a flaky test.** A test passes locally but flakes in CI — load this skill to check the determinism + no-network rules before chasing the symptom.
 ## Conventions
 1. **Frontend sibling rule.** Every new file in `src/` that contains testable logic gets a `*.test.ts(x)` next to it. `useFoo.ts` → `useFoo.test.ts`. `ClaimDrawer.tsx` → `ClaimDrawer.test.tsx`. The 59 existing siblings follow this; CI implicitly enforces it via the default `src/**/*.test.ts(x)` glob in `vitest.config.ts`.
 2. **Backend test location.** Tests live under `backend/tests/test_*.py`. Two flavors, two naming patterns:
   - **Integration tests** (FastAPI surface) → `test_api_<topic>_<verb>.py` — e.g. `test_api_parse_persists.py`, `test_api_999.py`.
   - **Pure-unit tests** (parsers, validators, store internals) → `test_<module>_<behavior>.py` — e.g. `test_cas_codes.py`, `test_pubsub.py`.
 3. **Prodfiles drop-in.** Real EDI samples live under `docs/prodfiles/<source>/<file>.txt` (sources seen so far: `837p-from-axiscare/`, `835fromco/`, `FromHPE/`, `claims/`). To use one in a test: copy the file to `backend/tests/fixtures/<descriptive-name>.txt` (flat — no per-test subdirectories; the existing 13 fixtures all sit at the top level) and reference it from the test as a module-level `Path` constant. See `## Patterns` for the exact line.
 4. **Determinism.** Time-sensitive tests must not depend on wall-clock time.
   - **Frontend** uses `vi.useFakeTimers()` + `vi.setSystemTime(new Date("YYYY-MM-DDTHH:MM:SSZ"))` (see `src/components/TailStatusPill.test.tsx:54-58`) and `vi.advanceTimersByTime(ms)` to drive interval / backoff code deterministically.
   - **Backend** dates are passed explicitly as fixture values — e.g. `datetime.now(timezone.utc)` is fine for "now-ish" anchors, but for fixed dates pass `datetime(2026, 6, 20, tzinfo=timezone.utc)`. The project does **not** currently use `freezegun` or `mock.patch(datetime)`; if you need deterministic date mocking, propose adding `freezegun` to `backend/pyproject.toml` rather than rolling your own.
 5. **No network.** Tests must not hit the network.
   - **Backend:** `fastapi.testclient.TestClient(app)` runs in-process; no uvicorn. The autouse `conftest.py` fixture (`backend/tests/conftest.py:20`) 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`.
   - **Frontend:** `vi.stubGlobal("fetch", vi.fn().mockResolvedValue(...))` for hooks; `vitest.config.ts` sets `VITE_API_BASE_URL=http://test.local` so the `api` module doesn't throw `notConfiguredError` before the mock fires.
 6. **pytest collection.** Run `cd backend && python -m pytest tests/<file>::<name> -v` for the fastest single-test feedback loop. Run `cd backend && python -m pytest tests/<file> -v` for one file. Run `cd backend && python -m pytest` for the full suite — this is the merge gate. Frontend: `npm test` (alias for `vitest run`) for the full suite; `npx vitest run src/hooks/useFoo.test.ts` for one file.
 ## Patterns
 ### Backend pytest using a fixture + per-test SQLite DB
 Canonical shape — see `backend/tests/test_api_999.py:1-50` for the full file. The autouse `conftest.py` already provides the DB init + `EventBus` reset; most tests just add a `client` fixture.
 ```python
 """Tests for the FastAPI surface in cyclone.api for the 999 endpoint."""
 from __future__ import annotations
 from pathlib import Path
 import pytest
 from fastapi.testclient import TestClient
 from cyclone.api import app
 # Fixture reference — flat, module-level Path constant. NEVER reach into
 # docs/prodfiles/ from a test; the fixtures/ dir is the test-consumed surface.
 ACCEPTED = Path(__file__).parent / "fixtures" / "minimal_999.txt"
 REJECTED = Path(__file__).parent / "fixtures" / "minimal_999_rejected.txt"
@pytest.fixture
 def client() -> TestClient:
    return TestClient(app)
 def test_parse_999_endpoint_happy_path(client: TestClient):
    text = ACCEPTED.read_text()
    resp = client.post(
        "/api/parse-999",
        files={"file": ("minimal_999.txt", text, "text/plain")},
        headers={"Accept": "application/json"},
    )
    assert resp.status_code == 200, resp.text
    body = resp.json()
    assert body["ack"]["ack_code"] == "A"
 ```
 Override the autouse DB fixture only when you need a custom env (e.g. a per-test backup directory) — see `backend/tests/test_999_rejected_state.py:20-25`:
 ```python
@pytest.fixture(autouse=True)
 def _setup(tmp_path, monkeypatch):
    monkeypatch.setenv("CYCLONE_DB_URL", f"sqlite:///{tmp_path}/inbox.db")
    from cyclone import db
    db._reset_for_tests()
    db.init_db()
    yield
 ```
 ### Frontend vitest `*.test.tsx` for a component using fake timers
 Pattern taken from `src/components/TailStatusPill.test.tsx:1-62` — uses `vi.useFakeTimers()` + `vi.setSystemTime(...)` to drive interval-based code deterministically.
 ```ts
 // @vitest-environment happy-dom
 // React's act warnings need an act-aware environment — mirror the other
 // hook tests in this repo.
 (globalThis as { IS_REACT_ACT_ENVIRONMENT?: boolean }).IS_REACT_ACT_ENVIRONMENT = true;
 import { afterEach, beforeEach, describe, expect, it, vi } from "vitest";
 import { MyComponent } from "./MyComponent";
 describe("MyComponent", () => {
  beforeEach(() => {
    vi.useFakeTimers();
    vi.setSystemTime(new Date("2026-06-20T12:00:30Z"));
  });
  afterEach(() => {
    vi.useRealTimers();
  });
  it("test_renders_after_interval_tick", () => {
    vi.advanceTimersByTime(30_000);  // drive the setInterval
    // …assert…
  });
 });
 ```
 ### Frontend vitest `*.test.tsx` for a component using `@testing-library/react` + `happy-dom`
 Pattern taken from `src/hooks/useInboxLanes.test.ts:1-80`. (A handful of older tests — `useClaimDetail.test.ts`, `useDrawerUrlState.test.ts`, `TailStatusPill.test.tsx` — roll a custom `createRoot`+`Probe` shim instead. Both styles are accepted; `@testing-library/react` is preferred when the hook has async dependencies because `waitFor` is built in.)
 ```ts
 // @vitest-environment happy-dom
 (globalThis as { IS_REACT_ACT_ENVIRONMENT?: boolean }).IS_REACT_ACT_ENVIRONMENT = true;
 import { afterEach, describe, expect, it, vi } from "vitest";
 import { act, cleanup, renderHook, waitFor } from "@testing-library/react";
 import { useMyHook } from "./useMyHook";
 vi.mock("@/lib/api", () => ({
  api: { fetchFoo: vi.fn() },
 }));
 afterEach(() => {
  cleanup();
  vi.unstubAllGlobals();
  vi.useRealTimers();
 });
 describe("useMyHook", () => {
  it("loads data on mount", async () => {
    vi.stubGlobal("fetch", vi.fn().mockResolvedValue({
      ok: true,
      json: async () => ({ items: [] }),
    }));
    const { result } = renderHook(() => useMyHook());
    await waitFor(() => expect(result.current.loading).toBe(false));
    expect(result.current.items).toEqual([]);
  });
 });
 ```
 ## Anti-patterns
 - **Don't put frontend tests in `src/__tests__/`.** No such directory exists in the codebase — `__tests__` only appears in the SP-catalog plan itself. Use the sibling rule (`useFoo.ts` → `useFoo.test.ts`).
 - **Don't reach into `docs/prodfiles/` directly from a test.** Always copy to `backend/tests/fixtures/<name>.txt` first. The prodfiles directory is the source-of-truth archive and may be reorganized; the fixtures directory is the test-consumed surface and is stable.
 - **Don't use wall-clock sleeps for timing.** A handful of legacy tests use `await new Promise((r) => setTimeout(r, 200))` (see `src/components/SearchBar.test.tsx:281,323,373` and `src/hooks/useSearch.test.ts:174`) — these are known flaky in CI. Use `vi.useFakeTimers()` + `vi.advanceTimersByTime(ms)` instead, or `waitFor(...)` from `@testing-library/react`.
 ## Related skills
 - **`cyclone-spec`** — every SP-N spec lists test impact; load this when drafting or reviewing the spec to confirm fixture / `.test.tsx` implications for the increment.
 - **`cyclone-edi`** — most backend tests cover parser + validator behavior; load when the increment touches an EDI parser or adds a validator rule (R200/R210/NPI Luhn/EIN/CAS).
 - **`cyclone-tail`** — most frontend tests cover hook behavior (`useTailStream`, `useMergedTail`); load when the increment changes the wire format or adds a streaming hook.
 - **`cyclone-store`** — write-path tests live here; load when the increment touches `store.py`, adds a new entity, or wires a new `<entity>_written` event.
 - **`cyclone-api-router`** — endpoint tests live in `backend/tests/test_api_*.py`; load when the increment adds or changes an HTTP endpoint.
 - **`cyclone-frontend-page`** — page-component tests live next to pages in `src/pages/*.test.tsx`; load when the increment adds or refactors a page.
 - **`cyclone-cli`** — CLI smoke tests live in `backend/tests/test_cli_*.py`; load when the increment adds a CLI subcommand.
 - **`superpowers:test-driven-development`** (global) — the upstream TDD workflow. Load first when starting any new feature increment; this skill only codifies the Cyclone-specific test layout on top of TDD.

 ## Pipeline automation agent
 For unattended round-trips (an agent / scheduler drops an 837P file
 into the pipeline and waits for the 999 back from Gainwell), see the
 `cyclone-pipeline` sibling project at `/Users/openclaw/dev/cyclone-pipeline/`.
 It drives the full 7-phase state machine — preflight → browser upload →
 parse verification → SFTP submit → TA1 wait → 999 wait → scan +
 report — with structured JSON logs, crash-safe resume, and a
 self-contained per-run folder under `./runs/`.
 ```bash
 # Single file
 cyclone-pipeline run /path/to/axiscare-837p.txt
 # Resume a crashed run
 cyclone-pipeline resume 2026-06-21-1430-001
 # On/after the following Monday, verify the 835 arrived
 cyclone-pipeline check-835 2026-06-21-1430-001
 ```
 The 835 is **not** waited for inline (it lands the following Monday on
 the CO Medicaid payment cycle). See
 [`cyclone-pipeline/README.md`](../cyclone-pipeline/README.md) for
 install, embed-in-agent example, exit codes, and the report format.

 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
 production** — it's a single env-var trip from wide-open to the public
 internet. The Docker compose file does not honor this flag.
 See `docs/superpowers/specs/2026-06-22-cyclone-auth-design.md` for the full
 design.

 ### Key rotation (SP15)
 `POST /api/admin/db/rotate-key` re-encrypts the SQLite file in place
 with a fresh SQLCipher key via `PRAGMA rekey`, then updates the
 Keychain so subsequent connections open with the new key. The
 rotation holds a module-level `threading.Lock` (so two concurrent
 requests can't race), disposes + rebuilds the SQLAlchemy engine with
 `NullPool` (so SQLCipher's thread affinity is honored), and writes a
 tamper-evident `db.key_rotated` audit event with old + new
 fingerprints and the post-rotation table count. The old key is
 retained in the `cyclone.db.key.previous` Keychain account for a
 grace period so a botched rotation can be rolled back by hand.
 ## NPI checksum + Tax ID format validation (SP20)
 Two pure local validators — no NPPES round-trip, no IRS e-file
 lookup. Catches the 99% case (a typo at the end of an NPI, a letter in
 an EIN, an extra digit, the reserved `00`/`07`/`8X` EIN prefix).
 | Check | Algorithm | Surface |
 |-------|-----------|---------|
 | NPI  | 10 digits where the last is a Luhn checksum over `80840 + body`. CMS-published example: body `123456789` → check `3` → valid NPI `1234567893`. | `cyclone.npi.is_valid_npi`, CLI `cyclone validate-npi <npi>`, API `GET /api/admin/validate-provider?npi=...`, validator rule `R021_npi_checksum` (warning) |
 | Tax ID (EIN) | 9 digits, optional `XX-XXXXXXX` formatting. Rejects reserved prefixes `00`, `07`, `80`–`89` (IRS Pension Plan Branch). | `cyclone.npi.is_valid_tax_id`, CLI `cyclone validate-tax-id <ein>`, API `GET /api/admin/validate-provider?tax_id=...` |
 ### CLI
 ```bash
 $ cyclone validate-npi 1234567893
 OK: 10-digit NPI passes Luhn checksum
 $ cyclone validate-npi 1234567890
 INVALID: '1234567890' fails NPI Luhn checksum   # exit 1
 $ cyclone validate-tax-id 72-1587149
 OK: 9-digit EIN (normalized=721587149)
 $ cyclone validate-tax-id 00-1234567
 INVALID: 9-digit EIN has reserved prefix (00); EIN is not assignable by IRS   # exit 1
 ```
 ### API
 ```bash
 curl 'http://localhost:8000/api/admin/validate-provider?npi=1234567893&tax_id=72-1587149'
 # {
 #   "npi":     {"valid": true,  "skipped": false},
 #   "tax_id":  {"valid": true,  "skipped": false, "normalized": "721587149"}
 # }
 ```
 Both query params are optional; omitted fields return
 `{"valid": null, "skipped": true}` so the caller can render "no check
 performed" rather than treating absent input as a hard fail.
 ### Parser integration
 The `R021_npi_checksum` rule runs alongside the existing `R020_npi_format`
 in `cyclone.parsers.validator`. A billing-provider NPI that passes
 R020 (right shape) but fails R021 (bad Luhn) is yielded as a
 **warning**, not an error — operators sometimes ingest test fixtures
 with placeholder NPIs (e.g. all-same-digit) and we don't want to block
 that path. In strict mode (`--strict` / `?strict=true`) warnings are
 promoted to errors.
 ### Files
 * `cyclone/npi.py` — new module (~155 LOC).
 * `cyclone.parsers.validator` — new `R021_npi_checksum` rule.
 * `cyclone.api_routers.admin` — new `validate-provider` endpoint.
 * `cyclone.cli` — `validate-npi` + `validate-tax-id` subcommands.
 * Tests: `test_npi.py` (27), `test_api_validate_provider.py` (4),
  `test_cli_validate.py` (8), `test_validator.py::test_r021_*` (4) —
  **43 new tests**.
 ## Security hardening (SP19)
 Three pure-ASGI middlewares sit in front of every FastAPI request.
 They're sized for Cyclone's local-only posture — a misconfigured
 Tailscale / ngrok bind, a buggy cron job uploading a 4 GB file, or a
 port-scraper — not for hostile internet exposure.
 | Middleware | Default | Override | Reject |
 |------------|---------|----------|--------|
 | `BodySizeLimitMiddleware` | 50 MB | `CYCLONE_MAX_BODY_BYTES` | `413 body_too_large` over Content-Length cap; chunked reads capped too |
 | `RateLimitMiddleware` | 300 req/min/IP | `CYCLONE_RATE_LIMIT_PER_MIN` | `429 rate_limited` over the sliding window; `/api/health` exempt |
 | `SecurityHeadersMiddleware` | always on | n/a | stamps `X-Content-Type-Options: nosniff`, `X-Frame-Options: DENY`, `Referrer-Policy: same-origin`, `Permissions-Policy`, `Content-Security-Policy: default-src 'none'; frame-ancestors 'none'` |
 Every rejection (413 / 429) also writes a tamper-evident
 `api.request_rejected` event into the SP11 audit chain so an
 operator can correlate a misbehaving client with the SP18 JSON logs:
 ```json
 {"event_type":"api.request_rejected","entity_id":"POST /api/parse-837","payload":{"status":413,"reason":"body_too_large","path":"/api/parse-837","method":"POST","ip":"127.0.0.1"}}
 ```
 ### Health probe
 `GET /api/health` now returns a subsystem snapshot:
 ```json
 {
  "status": "ok",
  "version": "0.1.0",
  "db":      {"ok": true},
  "scheduler": {"running": true, "interval_s": 60, "sftp_block": "co_medicaid",
                "backup_scheduler_running": false, "backup_interval_hours": 24.0},
  "pubsub":  {"parse_completed": 1, "batch_added": 1},
  "batch":   {"last_batch_id": 42, "last_batch_kind": "837P",
              "last_batch_at": "2026-06-21T15:30:00.123Z",
              "last_batch_filename": "TP11525703-837P-..."}
 }
 ```
 Returns `"status": "degraded"` if any subsystem reports an error —
 the per-subsystem dict still surfaces so an operator can see which
 one is unhappy. `/api/health` is rate-limit exempt so a load balancer
 hammering the endpoint doesn't trip the limiter.
 ### Files
 * `cyclone.security` — `BodySizeLimitMiddleware`,
  `RateLimitMiddleware`, `SecurityHeadersMiddleware`, and
  `get_health_snapshot()` (~330 LOC).
 * `cyclone.api_routers.health` rewritten to use `get_health_snapshot()`.
 * `cyclone.pubsub.EventBus.stats()` — new method that returns
  per-kind subscriber counts.
 * `tests/test_security.py` — 13 new tests.
 ## Structured logging (SP18)
 Cyclone emits newline-delimited JSON to stderr by default — readable
 by `jq`, Loki, Vector, ELK, or any log shipper. Every record carries
 `ts` (ISO 8601 ms UTC), `level`, `logger`, `msg`, and an optional
 `extra` dict for structured fields. Exceptions render as a
 `traceback` string.
 ```
 {"ts":"2026-06-21T15:30:00.123Z","level":"INFO","logger":"cyclone.scheduler","msg":"Processed inbound file","extra":{"input_filename":"ACK_999.x12","parser":"parse_999","claims":3}}
 {"ts":"2026-06-21T15:30:01.456Z","level":"ERROR","logger":"cyclone.api","msg":"Backup create failed","extra":{"reason":"BackupError: passphrase mismatch"},"traceback":"Traceback ..."}
 ```
 ### PII scrubbing
 A `PiiScrubber` filter is attached to the root logger and rewrites
 obvious PHI patterns to `<redacted:npi>` / `<redacted:ssn>` /
 `<redacted:dob>` / `<redacted:patient_name>` before any handler sees
 the record:
 | Pattern | Replacement |
 |---------|-------------|
 | `\b\d{10}\b` | `<redacted:npi>` |
 | `\b\d{3}-\d{2}-\d{4}\b` or `\b\d{9}\b` at phrase boundary | `<redacted:ssn>` |
 | `(dob\|date_of_birth)[:=]\s*\d{4}-\d{2}-\d{2}` | preserves the key, redacts the date |
 | `patient_name=...` | full chunk redacted |
 | Extras with key `dob`/`ssn`/`npi`/`patient_name`/… | value redacted regardless of shape |
 The scrubber is conservative — bare ISO dates without a `dob=` prefix
 are **not** scrubbed (they're too often timestamps or batch IDs), and
 11+ digit numbers are left alone (they can't be NPIs). Disable for
 forensic mode with `CYCLONE_LOG_NO_PII_SCRUB=1`.
 ### Knobs
 | Env var | Default | Meaning |
 |---------|---------|---------|
 | `CYCLONE_LOG_LEVEL` | `INFO` | Root logger level. `DEBUG` for troubleshooting. |
 | `CYCLONE_LOG_FILE` | (none) | Write to this path via `RotatingFileHandler` (10 MB × 5 backups). |
 | `CYCLONE_LOG_JSON` | `true` | `false` uses the dev tabular formatter. |
 | `CYCLONE_LOG_NO_PII_SCRUB` | (none) | `1` disables scrubbing. |
 CLI:
 ```
 cyclone --log-format=dev parse-837 sample.x12 --output-dir out/   # tabular for tail -f
 cyclone --log-file=/var/log/cyclone.log backup create              # JSON to rotating file
 ```
 The `parse-837` / `parse-835` subcommands also accept `--log-level`
 which re-runs `setup_logging()` so the per-invocation level overrides
 the group default.
 ### Files
 * `cyclone.logging_config` — `JsonFormatter`, `CycloneDevFormatter`,
  `PiiScrubber`, `setup_logging()`.
 * `tests/test_logging_formatter.py` (11), `test_logging_scrubber.py`
  (13), `test_logging_setup.py` (10) — 34 new tests.
 * `cyclone.api` lifespan calls `setup_logging()` first; the CLI
  `main` group does the same.
 ## Encrypted Backups (SP17)
 The BackupService takes an online consistent snapshot of the live
 SQLite file via SQLite's `.backup()` API, encrypts the bytes with
 AES-256-GCM, and writes a `.bin` + `.meta.json` pair into the backup
 directory (default `~/.local/share/cyclone/backups/`). The encryption
 key is derived from a separate passphrase in the macOS Keychain
 (PBKDF2-HMAC-SHA256, 200,000 iterations, 16-byte salt persisted to
 Keychain) — so a SQLCipher DB-key compromise does not unlock the
 backups, and a backup-passphrase compromise does not unlock the live
 DB. If neither is set, the service refuses (`BackupError`) rather than
 silently writing plaintext.
 | Method | Path | Purpose |
 | ------ | ---- | ------- |
 | POST   | `/api/admin/backup/create` | Take an encrypted backup now. |
 | GET    | `/api/admin/backup/list` | List `db_backups` rows (newest first, filterable). |
 | GET    | `/api/admin/backup/status` | Counts, disk usage, last-run timestamp, scheduler snapshot. |
 | POST   | `/api/admin/backup/{id}/verify` | Decrypt + SHA-256 verify against the sidecar. |
 | POST   | `/api/admin/backup/{id}/restore/initiate` | First step: get `restore_token` + preview (fingerprints of backup vs live). |
 | POST   | `/api/admin/backup/{id}/restore/confirm` | Second step: dispose engine, copy decrypted DB, rebuild engine. |
 | POST   | `/api/admin/backup/prune` | Apply retention policy now. |
 | POST   | `/api/admin/backup/scheduler/{start,stop,tick}` | Operate the backup scheduler. |
 Restore is two-step by design: an idle browser tab can't nuke the
 live DB. The first call returns a one-shot 64-char hex
 `restore_token` plus a side-by-side preview (`backup_db_fingerprint`,
 `backup_table_count`, `current_db_fingerprint`, `current_table_count`).
 The second call swaps the live engine only if the token matches
 within a 5-minute TTL.
 The scheduler (auto-start opt-in via `CYCLONE_BACKUP_AUTOSTART`)
 ticks every `CYCLONE_BACKUP_INTERVAL_HOURS` (default 24), runs
 `create_now` + `prune`, and writes audit events for each outcome
 (`db.backup_created`, `db.backup_failed`, `db.backup_pruned`,
 `db.backup_restored`). The CLI mirrors the API surface:
 ```bash
 cyclone backup init-passphrase      # one-time; interactive
 cyclone backup create
 cyclone backup list
 cyclone backup verify <id>
 cyclone backup restore <id> --yes
 cyclone backup prune --yes
 cyclone backup status
 ```
 Retention defaults to 30 days (`CYCLONE_BACKUP_RETENTION_DAYS`). The
 retention policy is best-effort: an operator who runs `cyclone
 backup create` manually retains full control.

  drives 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, and a per-run report. Pure Python 3.11+ (httpx, Playwright,
  Click, pydantic v2, structlog). The 835 is not waited for inline —
  it lands the following Monday — and is verified by a separate
  `check-835` subcommand. Embeddable as a library for OpenClaw / Nora
  agent integration. See
  [Pipeline automation agent](#pipeline-automation-agent) above.
 - **Sub-project 19 (shipped) — Security hardening + health probe.**
  Three pure-ASGI middlewares (`BodySizeLimitMiddleware`,
  `RateLimitMiddleware`, `SecurityHeadersMiddleware`) close the
  completeness-review gaps §3.1.4 (no body/rate limits) and §3.1.25
  (no CSP / security headers). 413/429 rejections emit a
  tamper-evident `api.request_rejected` audit event (SP11 chain).
  `/api/health` is now a rich subsystem snapshot — DB connectivity,
  MFT scheduler state, backup scheduler state, live pubsub
  subscriber counts, last batch id + timestamp. See
  [Security hardening (SP19)](#security-hardening-sp19) below.
 - **Sub-project 20 (shipped) — NPI checksum + Tax ID format validation.**
  Pure local validators (`cyclone.npi`) — no NPPES round-trip, no IRS
  e-file lookup. Catches the 99% typo case at parse time. NPI uses
  CMS-published Luhn over `80840 + body` (example: `1234567893` is
  valid). EIN rejects reserved prefixes (`00`, `07`, `80`–`89`).
  Surface: `cyclone validate-npi` / `validate-tax-id` CLI subcommands,
  `GET /api/admin/validate-provider`, new `R021_npi_checksum`
  validator rule (warning, not error — placeholder NPIs in test
  fixtures shouldn't block ingest). See
  [NPI checksum + Tax ID format validation (SP20)](#npi-checksum--tax-id-format-validation-sp20)
  below.
 - **Sub-project 18 (shipped) — Structured JSON logging.** All logs
  emitted by the API, CLI, scheduler tick loop, and backup service
  flow through a `JsonFormatter` (newline-delimited JSON, ISO-8601 ms
  timestamps) by default. A `PiiScrubber` filter redacts obvious PHI
  (NPIs, SSNs, DOBs, patient names) from message + extras — both via
  inline patterns (`npi 1881068062`) and via PHI-keyed extras
  (`extra={"dob": "1980-04-12"}`). Configurable via env vars
  (`CYCLONE_LOG_LEVEL`, `CYCLONE_LOG_FILE`, `CYCLONE_LOG_JSON`,
  `CYCLONE_LOG_NO_PII_SCRUB`) and CLI flags
  (`--log-format=json|dev`, `--log-file=…`); a tabular `CycloneDevFormatter`
  is the opt-out for `tail -f` in dev. See
  [Structured logging](#structured-logging-sp18) below.
 - **Sub-project 17 (shipped) — Encrypted DB backups.** Automated
  encrypted backups via AES-256-GCM (PBKDF2-HMAC-SHA256, 200k iters).
  The operator sets a separate passphrase in the macOS Keychain
  (`cyclone backup init-passphrase`); if missing, the service falls
  back to deriving from the SQLCipher DB key with a WARNING. Online
  backups via SQLite `.backup()`, two-step restore (`initiate` →
  `confirm` with one-shot 64-char hex token), retention pruning with
  a 30-day default, and a tamper-evident audit chain (`db.backup_created`,
  `db.backup_failed`, `db.backup_pruned`, `db.backup_restored`,
  `db.backup_passphrase_set`). Backup scheduler ticks every 24h
  (configurable); auto-start opt-in via `CYCLONE_BACKUP_AUTOSTART`.
  Seven admin endpoints + six CLI subcommands. See
  [Encrypted Backups](#encrypted-backups) below.
 - **Sub-project 16 (shipped) — Live MFT polling scheduler.** asyncio
  background loop polls the Gainwell MFT inbound path, downloads
  new files, and routes them through the right parser (999 / 835 /
  277CA / TA1). Idempotent (re-ticks skip already-processed files
  via the new `processed_inbound_files` table). Crash-safe (per-file
  try/except so a bad file doesn't stop the loop). Five admin
  endpoints (`/api/admin/scheduler/{status,start,stop,tick,processed-files}`).
 - **Sub-project 15 (shipped) — SQLCipher key rotation.** In-place
  rotation via `PRAGMA rekey`, serialized through a module-level
  `threading.Lock` and a SQLAlchemy `NullPool` to keep SQLCipher
  thread-affine under FastAPI's per-request threadpool. Writes a
  `db.key_rotated` audit event with old + new key fingerprints and
  post-rotation `table_count`. See
  [Encryption at Rest — Key rotation](#key-rotation).

 ## Docker
 A two-service `docker-compose.yml` is provided for operators who want
 a single `docker compose up` instead of running the backend and
 frontend in two terminals. Both services are configured to restart
 automatically on crash, and the SQLite database lives on a named
 volume that survives `docker compose down` (only `down -v` wipes it).
 ```bash
 docker compose up -d --build    # build + start both services in the background
 docker compose ps                # confirm both containers are Up (healthy)
 docker compose logs -f           # tail both logs
 open http://127.0.0.1:8081       # the SPA, served by nginx
 ```
 ### What's where
 | Service    | Image                  | Published port                | Healthcheck            | Persistent state          |
 | ---------- | ---------------------- | ----------------------------- | ---------------------- | ------------------------- |
 | `frontend` | `cyclone-frontend:local` | `0.0.0.0:8081 → 80` (LAN-reachable by default; tighten via `CYCLONE_BIND_ADDRESS=127.0.0.1`) | `GET /healthz`         | none                      |
 | `backend`  | `cyclone-backend:local`  | not published (see note)    | `GET /api/health`      | `cyclone-data` named volume at `/data` |
 The frontend's nginx reverse-proxies `/api/*` to the backend over the
 compose network, so the SPA talks to `http://same-origin/api/...` and
 the Vite dev-server config (`VITE_API_BASE_URL=`) doesn't apply — the
 build is invoked with an empty `VITE_API_BASE_URL` and the API calls
 are relative.
 ### Persistence
 The backend writes its SQLite file to `/data/cyclone.db` inside the
 container, which is backed by the named volume `cyclone-data`. Killing
 and restarting the container preserves the DB; rebooting the host
 preserves the DB; only `docker compose down -v` removes it. The
 container's `HEALTHCHECK` and `restart: unless-stopped` policy mean a
 crash is recovered within ~15 seconds (next healthcheck interval)
 without operator intervention.
 To back up the live database:
 ```bash
 docker compose exec backend sqlite3 /data/cyclone.db ".backup /data/backup.db"
 docker cp cyclone-backend:/data/backup.db ./cyclone-backup-$(date +%F).db
 ```
 (SQLite's online backup API — safe to run while the backend is
 serving traffic.)
 ### Crashing the backend on purpose
 To confirm the auto-restart wiring:
 ```bash
 docker compose kill -s SIGKILL backend       # hard-kill the backend
 docker compose ps                            # backend should restart within seconds
 docker compose logs --tail=20 backend        # see the uvicorn startup banner again
 ```
 Data is unaffected: the volume survives `kill` and the new process
 re-opens the same DB file.
 ### Talking to the backend directly
 The backend port is **not** published by default (everything goes
 through the frontend's nginx). To expose it for `curl` debugging,
 uncomment the `ports:` block under `backend:` in `docker-compose.yml`
 and restart:
 ```bash
 curl http://127.0.0.1:8000/api/health        # {"status":"ok","version":"..."}
 ```
 If 8081 clashes with something else on the host, run with a different
 published port:
 ```bash
 CYCLONE_WEB_PORT=9000 docker compose up -d
 open http://127.0.0.1:9000
 ```
 To reach the UI from another machine on your LAN, open
 `http://<host-lan-ip>:8081` — the default bind is `0.0.0.0`. To
 re-tighten to loopback-only (matching the standalone install's
 local-only posture):
 ```bash
 CYCLONE_BIND_ADDRESS=127.0.0.1 docker compose up -d
 ```
 ### Payer config
 `config/payers.yaml` is copied into the backend image at build time.
 Edit the YAML, rebuild, and either bounce the container or `POST
 /api/admin/reload-config` to pick up changes without a rebuild.

 Subcommands
 -----------
 - ``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``.

 - ``users set-role USERNAME --role {admin,user,viewer}`` — change role.
 Exit codes
 ----------

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

 """SP17 — Encrypted backup primitives.
 This module provides the low-level building blocks the rest of the
 backup stack uses:
 * ``derive_key``  — PBKDF2-HMAC-SHA256 key derivation (200,000
  iterations, 32-byte output). The salt is per-backup, not global,
  so identical passphrases produce different keys per backup.
 * ``encrypt`` / ``decrypt`` — AES-256-GCM authenticated encryption.
  Output layout: ``salt (16) | nonce (12) | ciphertext | tag (16)``.
  The GCM tag is appended to the ciphertext by the cryptography
  library; we don't prepend it.
 * ``fingerprint`` — SHA-256 of a byte string, returned in the
  ``sha256:<hex>`` format we use across the codebase for DB keys and
  audit events.
 * ``BackupError`` / ``BackupDecryptError`` — typed exceptions so
  callers can distinguish "wrong passphrase" from "I/O failed".
 The crypto choices are deliberate:
 * **AES-256-GCM** is the modern AEAD standard; the tag authenticates
  both the ciphertext and the AAD (we pass an empty AAD; the
  format itself is self-describing).
 * **PBKDF2-HMAC-SHA256 @ 200k iters** is OWASP's 2023+ minimum for
  PBKDF2-SHA256. Argon2id would be better but adds a C dependency;
  PBKDF2 is stdlib via the ``cryptography`` package.
 * **Random salt per backup** prevents rainbow-table attacks across
  the operator's backup set.
 * **Random 96-bit nonce per encryption** is what AES-GCM requires;
  we use ``os.urandom`` which is a CSPRNG on every platform we run
  on (macOS, Linux).

 """SP17 — High-level backup coordinator.
 Owns the lifecycle of every backup the operator (or the scheduler)
 takes:
 * ``create_now`` — runs SQLite's online ``.backup()`` against the
  live engine, encrypts the bytes with :func:`cyclone.backup.encrypt`,
  writes a ``.bin`` + ``.meta.json`` pair into the backup directory,
  and persists a row in ``db_backups``.
 * ``list_backups`` — directory listing joined with ``db_backups`` rows.
 * ``verify`` — decrypts + recomputes SHA-256, compares to the sidecar.
 * ``restore_initiate`` / ``restore_confirm`` — two-step restore so an
  idle browser tab can't nuke the live DB. The first call returns a
  ``restore_token`` (a random 32-byte hex string) plus a preview
  (``db_fingerprint``, ``table_count``). The second call swaps the
  engine only if the token matches.
 * ``prune`` — deletes backups older than ``retention_days``.
 This module is intentionally engine-aware: ``create_now`` reaches
 into the live SQLAlchemy engine to get a raw SQLite connection and
 call ``.backup()`` (the only way to take an online consistent
 snapshot). ``restore`` reaches into :func:`cyclone.db.dispose_engine`
 + :func:`cyclone.db.reinit_engine` to swap to the restored file.
 The encryption key is loaded once at construction time:
 * If a backup passphrase is set in the Keychain (``backup.passphrase``
  account under service ``cyclone``), use it directly with the salt
  stored in the companion ``backup.salt`` account. The salt must be
  persisted — a fresh random salt per process would defeat the key.
 * Otherwise fall back to deriving from the SQLCipher DB key + a fixed
  salt. Logged at WARNING because this is a degraded-but-still-safe
  posture.

 """SP18 — Structured JSON logging.
 Wraps Python's stdlib ``logging`` to emit newline-delimited JSON
 (or a dev-friendly tabular format) and to scrub obvious PHI
 patterns (NPIs, SSNs, DOBs, patient names) from the message +
 extra fields.
 Design choices
 --------------
 * **No third-party deps.** stdlib ``logging`` + ``json`` + ``re``
  is enough. ``loguru`` / ``structlog`` were considered; both add
  a dependency for marginal gain.
 * **JSON by default.** Operators running Cyclone in production
  almost certainly want logs in a format their aggregator
  (Loki/ELK/Vector) can parse. The dev format (``CycloneDevFormatter``)
  is the opt-out for ``tail -f`` in dev.
 * **Conservative PII scrubber.** Redacts unambiguous PHI patterns
  only. False positives are not free — an operator's diagnostic
  dump that says ``<redacted:npi>`` instead of the actual NPI
  makes root-causing a parse failure harder. The scrubber can be
  disabled with ``CYCLONE_LOG_NO_PII_SCRUB=1`` for tests /
  forensic mode.
 * **Idempotent setup.** :func:`setup_logging` can be called
  multiple times (CLI re-invocation, FastAPI lifespan re-entry
  under TestClient). Each call clears existing handlers on the
  root logger before attaching fresh ones — so the format toggle
  actually takes effect on the second call.

 """SP20 — NPI checksum + Tax ID format validation.
 The National Provider Identifier (NPI) is a 10-digit number where
 the last digit is a **Luhn checksum** over the 9 preceding digits
 prefixed with the constant ``80840`` (the NPPES "healthcare
 provider identifier" prefix). See CMS / HHS NPI Standard:
    https://www.cms.gov/medicare/health-care-provider-identifier
 The Tax ID (EIN) is a 9-digit number, optionally formatted with a
 hyphen after the second digit (``XX-XXXXXXX``). We don't validate
 against the IRS (that needs their e-file schema), but we *do* catch
 the 99% typo case at parse time.
 Everything in this module is local — no NPPES, no network. Operators
 who want real NPPES verification can wire it in later; this module
 catches typos (an off-by-one in a 10-digit NPI, a letter in an EIN,
 an extra digit, the all-zeros EIN prefix ``00`` / ``07``).

 """Background inbound MFT polling scheduler (SP16).
 Turns Cyclone from a manual upload tool into a live clearinghouse:
 a long-running asyncio task that periodically polls the Gainwell MFT
 inbound path, downloads each new file, and runs it through the
 appropriate parser. The operator no longer has to watch for inbound
 files and POST them to ``/api/parse-999`` etc. by hand.
 Design constraints
 ------------------
 * **Idempotent.** A re-tick (or a process restart) must not re-parse
  the same inbound file. We persist a ``processed_inbound_files`` row
  per file and skip ones we've already seen.
 * **Crash-safe.** If the parser raises or the DB write fails, the
  scheduler logs the error, records an ``error`` row, and moves on.
  The next tick continues from the next file.
 * **Bounded blast radius.** A bad file must not stop the scheduler.
  Each file is wrapped in try/except so a 999 parser crash doesn't
  prevent us from processing the next inbound 835.
 * **Operator-controlled.** The scheduler is OFF by default; the
  operator must explicitly start it (``POST /api/admin/scheduler/start``
  or ``CYCLONE_SCHEDULER_AUTOSTART=true``). When it's running, status
  is exposed via ``GET /api/admin/scheduler/status``.
 * **No threading.** We use ``asyncio.create_task`` + ``asyncio.sleep``
  rather than APScheduler or threading because the rest of the
  codebase is asyncio-native (FastAPI). The whole polling loop runs
  in the FastAPI event loop on the main thread.
 Compliance: SP16 is operational metadata only. Inbound file
 processing is NOT part of the HIPAA audit chain (SP11) — an SFTP
 outage shouldn't pollute the audit log with parser errors.

 """SP19 — Security middleware + health probe.
 Three concrete middlewares (body size, rate limit, security headers)
 plus a richer ``/api/health`` snapshot. Sizing is for Cyclone's
 local-only posture: a misconfigured Tailscale / ngrok bind, a
 misbehaving cron job, a port-scanner scraping the API. Anything more
 aggressive (auth, mTLS, WAF) is out of scope.
 Design choices
 --------------
 * **In-memory rate limiter.** Cyclone is single-process; a dict
  keyed by IP is enough. If we ever go multi-worker, swap for
  Redis. The rate-limit counter resets after the bucket window;
  failing open on the limiter itself (an unexpected exception)
  rather than 503ing every request is the right call for a local tool.
 * **Body-size check by Content-Length first, then chunked-read
  guard.** A chunked POST can lie about its size (or omit the
  header entirely); we cap read body size on the underlying stream
  so a malicious client can't keep streaming forever.
 * **Security headers on every response.** CSP locks the API to
  same-origin + the Vite dev origin (whitelisted explicitly so a
  future operator running on a different port doesn't break).
 * **Health snapshot is best-effort.** Each subsystem (DB,
  scheduler, pubsub) reports independently — a DB outage doesn't
  blank out the rest. ``status: "degraded"`` if any subsystem is
  unhappy; ``"ok"`` only when everything is.

 """Tests for the extended GET /api/config/providers/{npi} (SP21 Task 1.6).
 The endpoint gains two new top-level arrays for the drill-down panel:
 ``recent_claims`` (top 10 by submission date desc) and ``recent_activity``
 (top 10 by ``ts`` desc, joined to claims by ``claim_id`` because
 ``ActivityEvent`` has no direct ``provider_npi`` column).
 Existing SP9 fields (``label``, ``legal_name``, ``tax_id``,
 ``address_line1``, ``city``, ``state``, ``zip``, etc.) must remain
 present — the new arrays are additive only.
 The fixtures in ``fixtures/minimal_837p.txt`` and ``fixtures/minimal_835.txt``
 pair up to a single claim with ``provider_npi='1993999998'``. That NPI is
 NOT in the seeded provider set (Montrose/Delta/Salida → 1881068062/1851446637/

 canonical SP9 fixture NPI. The arrays come back as empty lists — the
 contract under test is the *shape* (array, ≤10) and the *backwards compat*
 of the existing fields; the data-path itself is exercised by the existing

 # Cyclone — local docker-compose stack.
 #
 # Two services on a user-defined network:
 #
 #   frontend  (nginx) — published on http://127.0.0.1:8080
 #                       serves the built SPA + reverse-proxies /api/* to backend
 #   backend   (uvicorn) — NOT published externally by default; reachable from
 #                          the frontend over the compose network on backend:8000
 #                          (override `ports:` below to expose it for curl/debug)
 #
 # Persistent state:
 #   - `cyclone-data` named volume mounted at /data in the backend holds
 #     the SQLite database file. Survives `docker compose down`; only
 #     `docker compose down -v` wipes it.
 #   - `config/payers.yaml` is baked into the backend image at build time.
 #     To edit payer config, change the YAML, rebuild the backend image,
 #     and `POST /api/admin/reload-config` (or just restart the container).
 #
 # Usage:
 #   docker compose up -d --build       # start (or rebuild + restart)
 #   docker compose logs -f             # tail both services
 #   docker compose restart backend     # bounce the backend (e.g. after crash)
 #   docker compose down                # stop containers, KEEP the data volume
 #   docker compose down -v             # stop AND wipe the data volume

 # Drop `UNIQUE(batch_id, patient_control_number)` + 409 UX Implementation Plan
 > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
 **Goal:** Allow multi-claim 837P files (where many `CLM*` segments share a `member_id`) to ingest without 409, and surface a structured error panel on the upload page when a true duplicate claim still trips a 409.
 **Architecture:** Backend migration drops the inline `UNIQUE(batch_id, patient_control_number)` on `claims` via SQLite table recreation. Two new store helpers (`find_existing_batch_for_claim`, `find_existing_batch_for_remit`) enable both 837 and 835 409 handlers to surface the id of the prior batch. Frontend `ApiError` carries `existingBatchId`; `Upload.tsx` renders an inline error panel above the streaming results with a link to the existing batch and a "Pick a different file" escape hatch.
 **Tech Stack:** Python 3.11+, SQLAlchemy 2.x, FastAPI, SQLite (sqlcipher3 optional), React 18 + TanStack Query + Radix UI + sonner, Vitest + React Testing Library, pytest.
 **Spec:** `docs/superpowers/specs/2026-06-21-cyclone-claims-unique-constraint-and-409-ux-design.md` — read fully before starting.
 **Worktree setup (one-time):**
 ```bash
 cd /Users/openclaw/dev/cyclone
 git worktree add .worktrees/claims-unique-fix -b claims-unique-fix main
 cd .worktrees/claims-unique-fix
 # Install backend deps if needed (venv assumed active)
 pip install -e backend
 # Install frontend deps if needed
 npm install
 ```
 All commits happen in this worktree. Merge to main via fast-forward when each phase ends.

 ## Phase 1 — Backend migration + helpers + API
 ### Task 1.1: Migration 0013 drops inline UNIQUE via table recreation
 **Files:**
 - Create: `backend/src/cyclone/migrations/0013_drop_claims_unique_constraint.sql`
 - Modify: `backend/tests/test_db_migrate.py` (append test)
 The runner (`backend/src/cyclone/db_migrate.py`) wraps each `.sql` in an implicit transaction via `engine.begin()`, so the migration MUST NOT use `BEGIN`/`COMMIT` or `PRAGMA foreign_keys=OFF` (no-op inside a transaction). Use `PRAGMA defer_foreign_keys = ON` instead — checks fire at commit against the renamed table.
 - [ ] **Step 1: Write the failing test**
 Add to `backend/tests/test_db_migrate.py`:
 ```python
 def test_drop_claims_unique_constraint_migration(tmp_path: Path, monkeypatch: pytest.MonkeyPatch) -> None:
    """Migration 0013 must drop the inline UNIQUE(batch_id, patient_control_number)
    on claims by recreating the table. Idempotent and preserves data."""
    monkeypatch.setattr(db_migrate, "MIGRATIONS_DIR", tmp_path)
    # Copy the real migrations so the test starts from v1.
    real_dir = Path(db_migrate.__file__).parent / "migrations"
    for src in sorted(real_dir.glob("00*.sql")):
        (tmp_path / src.name).write_text(src.read_text())
    engine = _fresh_engine(tmp_path)
    db_migrate.run(engine)
    # Before 0013: insert two claims with same (batch_id, patient_control_number) raises.
    with engine.begin() as c:
        c.exec_driver_sql("INSERT INTO batches(id, kind, input_filename, parsed_at) VALUES ('b1', '837p', 'x.txt', '2026-01-01')")

    # Now drop the migration in by name only:
    (tmp_path / "0013_drop_claims_unique_constraint.sql").write_text(
        "-- version: 13\n"
        "PRAGMA defer_foreign_keys = ON;\n"
        "CREATE TABLE claims_new ("
        "id TEXT PRIMARY KEY, batch_id TEXT NOT NULL REFERENCES batches(id) ON DELETE CASCADE,"

        "INSERT INTO claims_new SELECT * FROM claims;"
        "DROP TABLE claims;"
        "ALTER TABLE claims_new RENAME TO claims;"
    )
    db_migrate.run(engine)
    # After 0013: same insert succeeds.
    with engine.begin() as c:
        c.exec_driver_sql("INSERT INTO claims(id, batch_id, patient_control_number) VALUES ('c2', 'b1', 'M')")
        rows = c.exec_driver_sql("SELECT COUNT(*) FROM claims").scalar()
    assert rows == 2
    assert _user_version(engine) == 13
 def test_migration_0013_is_idempotent(tmp_path: Path, monkeypatch: pytest.MonkeyPatch) -> None:
    """Re-running db_migrate.run on a v13 DB is a no-op."""
    monkeypatch.setattr(db_migrate, "MIGRATIONS_DIR", tmp_path)
    real_dir = Path(db_migrate.__file__).parent / "migrations"
    for src in sorted(real_dir.glob("00*.sql")):
        (tmp_path / src.name).write_text(src.read_text())
    engine = _fresh_engine(tmp_path)
    db_migrate.run(engine)  # applies all
    version_after_first = _user_version(engine)
    db_migrate.run(engine)  # second call: no-op
    assert _user_version(engine) == version_after_first
 ```
 - [ ] **Step 2: Run test to verify it fails**
 Run: `cd backend && python -m pytest tests/test_db_migrate.py::test_drop_claims_unique_constraint_migration tests/test_db_migrate.py::test_migration_0013_is_idempotent -v`
 Expected: `test_drop_claims_unique_constraint_migration` FAILS because 0013 doesn't exist yet; `test_migration_0013_is_idempotent` PASSES (idempotency already works for any v).
 - [ ] **Step 3: Write migration 0013**
 Create `backend/src/cyclone/migrations/0013_drop_claims_unique_constraint.sql`:
 ```sql
 -- version: 13
 -- Drop the inline UNIQUE(batch_id, patient_control_number) on claims.
 -- Migration 0003 attempted DROP INDEX IF EXISTS uq_claims_batch_pcn but
 -- the constraint is inline in CREATE TABLE, so the drop was a no-op.
 -- The only way to remove an inline UNIQUE in SQLite is table recreation.
 --
 -- X12 837P allows any number of CLM segments per 2000B subscriber loop;
 -- claim identity is provided by the primary key (claims.id = CLM01).
 -- The remittances table had a parallel constraint already removed in 0003
 -- (because that one WAS a named index), so this migration only touches
 -- claims.
 --
 -- The migration runner (db_migrate.py) wraps each .sql in an implicit
 -- transaction via engine.begin(), so we MUST NOT use BEGIN/COMMIT.
 -- PRAGMA defer_foreign_keys defers FK checks to commit, which is the
 -- only way to drop a referenced table inside a transaction in SQLite.
 PRAGMA defer_foreign_keys = ON;
 CREATE TABLE claims_new (
    id TEXT PRIMARY KEY,
    batch_id TEXT NOT NULL REFERENCES batches(id) ON DELETE CASCADE,
    patient_control_number TEXT NOT NULL,
    service_date_from DATE,
    service_date_to DATE,
    charge_amount NUMERIC(12, 2) NOT NULL DEFAULT 0,
    provider_npi TEXT,
    payer_id TEXT,
    state TEXT NOT NULL DEFAULT 'submitted',
    state_before_reversal TEXT,
    matched_remittance_id TEXT REFERENCES remittances(id),
    raw_json TEXT,
    rejection_reason TEXT,
    rejected_at TIMESTAMP,
    resubmit_count INTEGER NOT NULL DEFAULT 0,
    state_changed_at TIMESTAMP,
    payer_rejected_at TEXT,
    payer_rejected_reason TEXT,
    payer_rejected_status_code TEXT,
    payer_rejected_by_277ca_id TEXT,
    payer_rejected_acknowledged_at TEXT,
    payer_rejected_acknowledged_actor TEXT
    -- NO UNIQUE (batch_id, patient_control_number) — removed.
 );
 INSERT INTO claims_new SELECT * FROM claims;
 DROP TABLE claims;
 ALTER TABLE claims_new RENAME TO claims;
 -- Recreate secondary indexes (same names, same columns as initial schema
 -- plus later migrations).
 CREATE INDEX ix_claims_state ON claims(state);
 CREATE INDEX ix_claims_patient_control_number ON claims(patient_control_number);
 CREATE INDEX ix_claims_service_date_from ON claims(service_date_from);
 CREATE INDEX ix_claims_state_changed_at ON claims(state, state_changed_at);
 CREATE INDEX idx_claims_payer_rejected_at ON claims(payer_rejected_at);
 CREATE INDEX idx_claims_payer_rejected_unack
    ON claims(payer_rejected_at)
    WHERE payer_rejected_acknowledged_at IS NULL;
 ```
 - [ ] **Step 4: Run tests to verify they pass**
 Run: `cd backend && python -m pytest tests/test_db_migrate.py::test_drop_claims_unique_constraint_migration tests/test_db_migrate.py::test_migration_0013_is_idempotent -v`
 Expected: PASS for both. The first test asserts the inline UNIQUE is gone (insert succeeds) and `user_version==13`. The second asserts idempotency.
 - [ ] **Step 5: Commit**
 ```bash
 git add backend/src/cyclone/migrations/0013_drop_claims_unique_constraint.sql backend/tests/test_db_migrate.py
 git commit -m "feat(db): drop inline UNIQUE(batch_id, patient_control_number) via migration 0013"
 ```

 ### Task 1.2: Store helpers `find_existing_batch_for_claim` and `find_existing_batch_for_remit`
 **Files:**
 - Modify: `backend/src/cyclone/store.py:1-50` (imports) and add new functions near the top
 - Modify: `backend/tests/test_store.py` (append tests)
 The helpers are pure reads. They return the batch_id of the first batch containing the given claim_id / remit_id, or None.
 - [ ] **Step 1: Write the failing test**
 Add to `backend/tests/test_store.py`:
 ```python
 def test_find_existing_batch_for_claim_returns_none_for_unknown(global_store):
    """Unknown claim_id -> None."""
    assert global_store.find_existing_batch_for_claim("nope") is None  # type: ignore[attr-defined]

    from datetime import datetime, timezone
    from cyclone.parser.parsers_837p import ClaimOutput  # noqa: F401
    # Simpler: insert a batch + claim directly via the DB.
    with _db_mod.SessionLocal()() as s:
        s.add(Batch(id="B1", kind="837p", input_filename="x.txt",
                    parsed_at=datetime(2026,1,1,tzinfo=timezone.utc)))
        s.add(Claim(id="CLM-A", batch_id="B1", patient_control_number="M1"))
        s.commit()
    assert global_store.find_existing_batch_for_claim("CLM-A") == "B1"  # type: ignore[attr-defined]

    """Unknown remit id -> None."""
    assert global_store.find_existing_batch_for_remit("nope") is None  # type: ignore[attr-defined]
 def test_find_existing_batch_for_remit_returns_batch_id(global_store):
    """Known remit id -> batch_id of the holding batch."""
    from cyclone.db import Batch, Remittance, db as _db_mod
    from datetime import datetime, timezone
    with _db_mod.SessionLocal()() as s:
        s.add(Batch(id="B2", kind="835", input_filename="y.txt",
                    parsed_at=datetime(2026,1,1,tzinfo=timezone.utc)))
        s.add(Remittance(id="CLP-A", batch_id="B2",
                         payer_claim_control_number="CLP-A",
                         status_code="1", received_at=datetime(2026,1,1,tzinfo=timezone.utc)))
        s.commit()
    assert global_store.find_existing_batch_for_remit("CLP-A") == "B2"  # type: ignore[attr-defined]
 ```
 - [ ] **Step 2: Run test to verify it fails**
 Run: `cd backend && python -m pytest tests/test_store.py::test_find_existing_batch_for_claim_returns_none_for_unknown -v`
 Expected: FAIL with `AttributeError: 'CycloneStore' object has no attribute 'find_existing_batch_for_claim'`.
 - [ ] **Step 3: Implement helpers**
 Add to `backend/src/cyclone/store.py` near the top, after imports:
 ```python
 def find_existing_batch_for_claim(claim_id: str) -> str | None:
    """Return the batch_id of the first batch containing this claim id, or None.
    Pure read; opens a short-lived session. Used by the 837 409 handler to

    """
    from sqlalchemy import select
    from cyclone import db
    from cyclone.db import Claim
    with db.SessionLocal()() as s:
        row = s.execute(

        ).first()
        return row[0] if row else None
 def find_existing_batch_for_remit(remit_id: str) -> str | None:
    """Return the batch_id of the first batch containing this remit id, or None.
    Pure read; opens a short-lived session. Used by the 835 409 handler.

        ).first()
        return row[0] if row else None
 ```
 - [ ] **Step 4: Run tests to verify they pass**
 Run: `cd backend && python -m pytest tests/test_store.py -k "find_existing_batch" -v`
 Expected: PASS for all 4 tests.
 - [ ] **Step 5: Commit**
 ```bash

 ### Task 1.3: 409 handlers in api.py surface `existing_batch_id`
 **Files:**
 - Modify: `backend/src/cyclone/api.py:394-415` (837 409 handler)
 - Modify: `backend/src/cyclone/api.py:588-602` (835 409 handler)
 - Modify: `backend/tests/test_api_parse_persists.py` (append tests)
 After migration 0013, IntegrityError on the 837 path can only fire when two claims in the same file share the same CLM01 (rare). The helper may still return a batch_id if the colliding CLM01 was previously ingested and not deleted (the dedup `s.get(Claim, claim_id)` only queries DB state, not pending session state, so cross-batch duplicates still get inserted and trip the PK).
 - [ ] **Step 1: Write the failing tests**
 Add to `backend/tests/test_api_parse_persists.py`:
 ```python

 Note: the 835 test is intentionally skipped — constructing a minimal valid 835 with duplicate CLP01 is brittle. The 837 case exercises the handler pattern (call `find_existing_batch_for_remit` from a similarly-shaped except block in the 835 handler). If you need 835 coverage, manually inspect by running the API on a real fixture after the implementation lands.

 ## Phase 2 — Frontend
 ### Task 2.1: `ApiError.existingBatchId` + parse837/835 surface it
 **Files:**
 - Modify: `src/lib/api.ts:164-167` (ApiError class)
 - Modify: `src/lib/api.ts:174-191` (readErrorBody)
 - Modify: `src/lib/api.ts:280-339` (parse837, parse835)
 - Create: `src/lib/api.test.ts`
 - [ ] **Step 1: Write the failing test**
 Create `src/lib/api.test.ts`:
 ```typescript
 import { describe, it, expect, vi, afterEach } from "vitest";
 import { ApiError, parse837 } from "@/lib/api";
 afterEach(() => vi.restoreAllMocks());
 describe("ApiError", () => {
  it("carries existingBatchId when constructed", () => {
    const e = new ApiError(409, "dup", "BATCH-1");
    expect(e.status).toBe(409);
    expect(e.existingBatchId).toBe("BATCH-1");
  });
  it("defaults existingBatchId to null", () => {
    const e = new ApiError(500, "boom");
    expect(e.existingBatchId).toBeNull();
  });
 });
 describe("parse837 throws ApiError with existingBatchId", () => {
  it("extracts existing_batch_id from 409 body", async () => {
    vi.stubGlobal("import.meta.env", { VITE_API_BASE_URL: "http://x" });
    const res = new Response(
      JSON.stringify({
        error: "Duplicate claim",
        detail: "collision",
        batch_id: "NEW",
        existing_batch_id: "PRIOR",
      }),
      { status: 409, headers: { "Content-Type": "application/json" } },
    );
    vi.stubGlobal(
      "fetch",
      vi.fn(async () => res),
    );
    const file = new File(["x"], "f.txt", { type: "text/plain" });
    await expect(parse837(file, { onProgress: () => {} })).rejects.toMatchObject({
      status: 409,
      existingBatchId: "PRIOR",
    });
  });
  it("sets existingBatchId null when body omits it", async () => {
    vi.stubGlobal("import.meta.env", { VITE_API_BASE_URL: "http://x" });
    const res = new Response(
      JSON.stringify({ error: "X", detail: "y", batch_id: "N" }),
      { status: 409, headers: { "Content-Type": "application/json" } },
    );
    vi.stubGlobal(
      "fetch",
      vi.fn(async () => res),
    );
    const file = new File(["x"], "f.txt", { type: "text/plain" });
    await expect(parse837(file)).rejects.toMatchObject({
      status: 409,
      existingBatchId: null,
    });
  });
 });
 ```
 - [ ] **Step 2: Run test to verify it fails**
 Run: `cd /Users/openclaw/dev/cyclone/.worktrees/claims-unique-fix && npm test -- src/lib/api.test.ts`
 Expected: FAIL — `existingBatchId` not a constructor argument yet; `parse837` throws `Error` not `ApiError`.
 - [ ] **Step 3: Update `ApiError`**
 Edit `src/lib/api.ts` line 164-167:
 ```typescript
 export class ApiError extends Error {
  constructor(
    public status: number,
    message: string,
    public existingBatchId: string | null = null,
  ) {
    super(message);
  }
 }
 ```
 - [ ] **Step 4: Update `readErrorBody` to return parsed body**
 Edit `src/lib/api.ts` line 174-191. Change return type and add JSON parse branch:
 ```typescript
 type ErrorBody = {
  detail?: unknown;
  error?: unknown;
  existing_batch_id?: unknown;
 };
 async function readErrorBody(
  res: Response,
 ): Promise<{ message: string; existingBatchId: string | null }> {
  try {
    const t = await res.text();
    if (!t) return { message: "", existingBatchId: null };
    try {
      const obj = JSON.parse(t) as ErrorBody;
      let message = "";
      if (typeof obj.detail === "string") message = obj.detail;
      else if (typeof obj.error === "string") message = obj.error;
      else message = t;
      const existing =
        typeof obj.existing_batch_id === "string"
          ? obj.existing_batch_id
          : null;
      return { message, existingBatchId: existing };
    } catch {
      return { message: t, existingBatchId: null };
    }
  } catch {
    return { message: "", existingBatchId: null };
  }
 }
 ```
 - [ ] **Step 5: Update parse837 to throw ApiError**
 Edit `src/lib/api.ts` lines 293-298:
 ```typescript
  if (!res.ok) {
    const { message, existingBatchId } = await readErrorBody(res);
    throw new ApiError(
      res.status,
      `${res.status} ${res.statusText}${message ? ` — ${message}` : ""}`,
      existingBatchId,
    );
  }
 ```
 - [ ] **Step 6: Update parse835 to throw ApiError**
 Edit `src/lib/api.ts` lines 329-334:
 ```typescript
  if (!res.ok) {
    const { message, existingBatchId } = await readErrorBody(res);
    throw new ApiError(
      res.status,
      `${res.status} ${res.statusText}${message ? ` — ${message}` : ""}`,
      existingBatchId,
    );
  }
 ```
 - [ ] **Step 7: Run tests to verify they pass**
 Run: `cd .worktrees/claims-unique-fix && npm test -- src/lib/api.test.ts`
 Expected: PASS for all 4 tests.
 - [ ] **Step 8: Commit**
 ```bash
 git add src/lib/api.ts src/lib/api.test.ts
 git commit -m "feat(api): ApiError carries existingBatchId; parse837/parse835 surface it"
 ```

 ### Task 2.2: `Upload.tsx` inline error panel for 409
 **Files:**
 - Modify: `src/pages/Upload.tsx` (add error state + panel JSX + 409 catch branch)
 - Create: `src/pages/Upload.test.tsx`
 The panel renders above the streaming results when `uploadError.kind === "duplicate"`. It shows:
 - A 409 badge
 - "Duplicate claim — file not ingested" title
 - Detail mentioning the file and (if `existingBatchId` is set) "Open the existing batch to compare, or pick a different file."
 - A button linking to `/batches/{existingBatchId}` if present
 - A "Pick a different file" ghost button that calls `pickFile(null)` and clears the error state
 - [ ] **Step 1: Write the failing tests**
 Create `src/pages/Upload.test.tsx`:
 ```tsx
 import { describe, it, expect, vi, beforeEach } from "vitest";
 import { render, screen, fireEvent } from "@testing-library/react";
 import { MemoryRouter, Route, Routes } from "react-router-dom";
 import { QueryClient, QueryClientProvider } from "@tanstack/react-query";
 import * as apiModule from "@/lib/api";
 import { ApiError } from "@/lib/api";
 import { Upload } from "@/pages/Upload";
 // We mock the api module so the component doesn't actually call fetch.
 vi.mock("@/lib/api", async () => {
  const actual = await vi.importActual<typeof apiModule>("@/lib/api");
  return { ...actual, parse837: vi.fn(), parse835: vi.fn() };
 });
 beforeEach(() => {
  vi.clearAllMocks();
 });
 function renderUpload() {
  const qc = new QueryClient({ defaultOptions: { queries: { retry: false } } });
  return render(
    <QueryClientProvider client={qc}>
      <MemoryRouter initialEntries={["/upload"]}>
        <Routes>
          <Route path="/upload" element={<Upload />} />
          <Route path="/batches/:id" element={<div data-testid="batch-page" />} />
        </Routes>
      </MemoryRouter>
    </QueryClientProvider>,
  );
 }
 describe("Upload error panel", () => {
  it("renders panel with link when 409 carries existingBatchId", async () => {
    vi.mocked(apiModule.parse837).mockRejectedValueOnce(
      new ApiError(409, "409 Conflict — dup", "PRIOR-BATCH"),
    );
    renderUpload();
    // Find the file input and upload a file.
    const input = document.querySelector('input[type="file"]') as HTMLInputElement;
    expect(input).toBeTruthy();
    const file = new File(["x"], "test.txt", { type: "text/plain" });
    fireEvent.change(input, { target: { files: [file] } });
    // Wait for the panel to render.
    const link = await screen.findByRole("button", { name: /open existing batch/i });
    expect(link).toBeInTheDocument();
    expect(screen.getByText(/duplicate claim/i)).toBeInTheDocument();
  });
  it("renders panel without link when 409 omits existingBatchId", async () => {
    vi.mocked(apiModule.parse837).mockRejectedValueOnce(
      new ApiError(409, "409 Conflict — dup", null),
    );
    renderUpload();
    const input = document.querySelector('input[type="file"]') as HTMLInputElement;
    const file = new File(["x"], "test.txt", { type: "text/plain" });
    fireEvent.change(input, { target: { files: [file] } });
    await screen.findByText(/duplicate claim/i);
    expect(
      screen.queryByRole("button", { name: /open existing batch/i }),
    ).toBeNull();
  });
  it("does NOT render panel for non-409 errors", async () => {
    vi.mocked(apiModule.parse837).mockRejectedValueOnce(
      new ApiError(400, "bad file"),
    );
    renderUpload();
    const input = document.querySelector('input[type="file"]') as HTMLInputElement;
    const file = new File(["x"], "test.txt", { type: "text/plain" });
    fireEvent.change(input, { target: { files: [file] } });
    // Give the async error handler a tick.
    await new Promise((r) => setTimeout(r, 50));
    expect(screen.queryByText(/duplicate claim/i)).toBeNull();
  });
  it("'Pick a different file' button clears error", async () => {
    vi.mocked(apiModule.parse837).mockRejectedValueOnce(
      new ApiError(409, "409 Conflict — dup", "PRIOR"),
    );
    renderUpload();
    const input = document.querySelector('input[type="file"]') as HTMLInputElement;
    const file = new File(["x"], "test.txt", { type: "text/plain" });
    fireEvent.change(input, { target: { files: [file] } });
    const clearBtn = await screen.findByRole("button", { name: /pick a different file/i });
    fireEvent.click(clearBtn);
    expect(screen.queryByText(/duplicate claim/i)).toBeNull();
  });
 });
 ```
 - [ ] **Step 2: Run test to verify it fails**
 Run: `cd .worktrees/claims-unique-fix && npm test -- src/pages/Upload.test.tsx`
 Expected: FAIL — no error panel exists yet, all 4 tests fail.
 - [ ] **Step 3: Add error state and 409 catch branch in Upload.tsx**
 Edit `src/pages/Upload.tsx`:
 1. At the top imports, add:
 ```tsx
 import { ApiError } from "@/lib/api";
 import { useNavigate } from "react-router-dom";
 ```
 2. Find the existing error-handling catch block (around line 683-687) and replace with:
 ```tsx
    } catch (err) {
      if (err instanceof ApiError && err.status === 409) {
        setUploadError({
          kind: "duplicate",
          existingBatchId: err.existingBatchId,
          filename: file.name,
        });
        toast.error("Duplicate claim — file not ingested");
      } else {
        toast.error(
          err instanceof Error ? err.message : "Failed to parse file"
        );
      }
    }
 ```
 3. Add state declaration near the other useState calls:
 ```tsx
  type UploadError =
    | { kind: "duplicate"; existingBatchId: string | null; filename: string };
  const [uploadError, setUploadError] = useState<UploadError | null>(null);
  const navigate = useNavigate();
 ```
 4. In the JSX, add the inline panel above the streaming-results section. Find the place where streaming results render (search for "streamDelay" or the section that shows the parsed batch) and insert just before it:
 ```tsx
 {uploadError && uploadError.kind === "duplicate" ? (
  <div
    role="alert"
    data-testid="duplicate-error-panel"
    className="error-panel mx-auto max-w-3xl rounded-md border border-destructive/40 bg-destructive/5 p-4"
  >
    <div className="flex items-center gap-2">
      <span className="inline-flex items-center rounded-md bg-destructive px-2 py-0.5 text-xs font-semibold text-destructive-foreground">
        409
      </span>
      <span className="font-semibold">Duplicate claim — file not ingested</span>
    </div>
    <p className="mt-2 text-sm text-muted-foreground">
      <span className="font-mono">{uploadError.filename}</span> collides with an
      existing record.
      {uploadError.existingBatchId
        ? " Open the existing batch to compare, or pick a different file."
        : " Pick a different file."}
    </p>
    <div className="mt-3 flex gap-2">
      {uploadError.existingBatchId ? (
        <Button
          onClick={() => navigate(`/batches/${uploadError.existingBatchId}`)}
        >
          Open existing batch →
        </Button>
      ) : null}
      <Button
        variant="ghost"
        onClick={() => {
          setUploadError(null);
          pickFile(null);
        }}
      >
        Pick a different file
      </Button>
    </div>
  </div>
 ) : null}
 ```
 - [ ] **Step 4: Run tests to verify they pass**
 Run: `cd .worktrees/claims-unique-fix && npm test -- src/pages/Upload.test.tsx`
 Expected: PASS for all 4 tests.
 - [ ] **Step 5: Commit**
 ```bash
 git add src/pages/Upload.tsx src/pages/Upload.test.tsx
 git commit -m "feat(upload): inline 409 error panel with existing-batch link"
 ```
 ---
 ## Phase 3 — End-to-end verification
 ### Task 3.1: Repro the original 409 with the actual multi-claim 837P file
 **Files:** none (manual verification)
 - [ ] **Step 1: Start backend + frontend**
 In one terminal: `cd backend && uvicorn cyclone.api:app --reload --port 8000`
 In another: `cd .worktrees/claims-unique-fix && npm run dev`
 - [ ] **Step 2: Upload the reproducer file**
 Use `docs/prodfiles/837p-from-axiscare/tp11525703-837P-20260618153339862-1of1.txt` (93696 bytes, 28 NM1*IL segments, multi-claim member-id collisions).
 Expected: 200 OK + batch persisted with multiple claims having identical `member_id` (this was previously 409).
 - [ ] **Step 3: Re-upload the same file to trigger 409**
 Expected: 409 with `existing_batch_id` pointing at the first batch.
 - [ ] **Step 4: Verify inline panel in the browser**
 Open the upload page, drag the file in, verify the panel appears with the "Open existing batch →" link.
 - [ ] **Step 5: Commit any tweaks**
 If the panel needed any styling tweaks (e.g. spacing, colors), commit them:
 ```bash
 git add src/pages/Upload.tsx
 git commit -m "polish(upload): 409 error panel visual tweaks"
 ```
 ---
 ## Self-review checklist (run after writing the plan)
 1. **Spec coverage** — Each section of the spec maps to a task:
   - §3 Schema migration → Task 1.1
   - §4 Store helpers → Task 1.2
   - §5 API change → Task 1.3
   - §6 Frontend `ApiError.existingBatchId` → Task 2.1
   - §6 Frontend `Upload.tsx` panel → Task 2.2
   - §10 Test plan (9 tests) → All 9 covered (5 backend + 4 frontend)
 2. **Placeholder scan** — No "TBD", "TODO", "implement later" markers. The only intentional skip is the 835 duplicate-CLP01 test, called out explicitly.
 3. **Type consistency** —
   - `find_existing_batch_for_claim` / `find_existing_batch_for_remit` return `str | None` everywhere.
   - `ApiError.existingBatchId` is `string | null` in TS and `str | None` everywhere it's referenced.
   - `setUploadError` payload shape `{ kind: "duplicate"; existingBatchId: string | null; filename: string }` is consistent in JSX and the catch branch.
 4. **Risk acknowledged** — Migration reversibility, loss of uniqueness, race window are all documented in spec §9 and reflected in test scope (we don't test the race condition).

 # Cyclone Skill Catalog Implementation Plan
 > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
 **Goal:** Ship 8 layer-mapped Cyclone skills under `.superpowers/skills/` (one per PR), then update the README to advertise the catalog. No code changes — pure guidance artifacts.
 **Architecture:** Each skill is a single `SKILL.md` (150–250 lines, YAML frontmatter + sections per the spec template). One commit per skill. Phase order matches the spec's build order so each later skill can ship its `## Related skills` section pointing to skills that already exist.
 **Tech Stack:** Markdown, YAML frontmatter. No build step, no runtime, no tests (skills are guidance, not code).
 **Spec:** [`docs/superpowers/specs/2026-06-21-cyclone-skill-catalog-design.md`](../specs/2026-06-21-cyclone-skill-catalog-design.md)

 - `description` is the only thing the auto-loader sees. One sentence, max ~200 chars. Include a `Use when:` clause listing the trigger situations.

 ## Task 0: Pre-flight — verify starting state
 **Goal:** Confirm `.superpowers/skills/` does not exist yet, capture a directory snapshot, and verify the catalog can be served from project scope.
 **Files:**
 - Read: `.superpowers/` (existing project-scoped superpowers directory)
 - Create (no commit): `/tmp/cyclone-skill-baseline.txt`
 - [ ] **Step 1: Inspect existing `.superpowers/` contents**
 ```bash
 ls -la .superpowers/
 ```
 Expected: shows only `plans/` and `specs/` directories (the canonical superpowers content for this repo). No `skills/` directory yet.
 - [ ] **Step 2: Confirm no stray skill files outside `.superpowers/skills/`**
 ```bash
 find . -path ./node_modules -prune -o -path ./.git -prune -o -path ./backend/.venv -prune -o -name "SKILL.md" -print
 ```
 Expected: no output (or only paths under `.grok/` system directories that are not part of the repo).
 - [ ] **Step 3: Verify the README's skills section is empty (or absent)**
 ```bash
 grep -n -i "skill" README.md | head -10
 ```
 Expected: a few hits for "skill" in unrelated contexts (e.g. "skill set" in marketing copy) but no existing catalog section.
 - [ ] **Step 4: Save the baseline**
 ```bash
 ls .superpowers/ | tee /tmp/cyclone-skill-baseline.txt
 ```
 Expected: `plans\nspecs`.
 No commit. Pre-flight only.
 ---
 ## Task 1: Phase 1, Skill 1 — `cyclone-spec`
 **Goal:** Codify the SP-N superpowers flow that this repo already uses (14 specs, 8 plans on disk). Pure documentation; this skill owns the convention so every later feature goes through it consistently.
 **Files:**
 - Create: `.superpowers/skills/cyclone-spec/SKILL.md`
 - [ ] **Step 1: Confirm the SP-N flow materials exist**
 ```bash
 ls docs/superpowers/specs/ | wc -l
 ls docs/superpowers/plans/ | wc -l
 git log --oneline | grep -E "^(feat|docs|merge): SP[0-9]+" | head -5
 ```
 Expected: ≥ 14 specs, ≥ 8 plans, ≥ 5 SP-N commits in history. Record the numbers for use in the skill.
 - [ ] **Step 2: Create the directory**
 ```bash
 mkdir -p .superpowers/skills/cyclone-spec
 ```
 - [ ] **Step 3: Write the SKILL.md**
 Use the shared template. Frontmatter:
 ```yaml
 ---
 name: cyclone-spec
 description: "Cyclone SP-N superpowers increment flow — spec → plan → implement → merge. Use when: starting a new numbered feature increment, naming a branch, opening a SP-N PR, or doing the merge dance into main."
 ---
 ```
 Body sections (each must be present, in this order):
 - `## When to use` — 4 bullets covering: starting a new increment, naming the spec/plan files, opening the PR, performing the merge.
 - `## Conventions` — at minimum these numbered rules:
  1. **Numbering.** Reserve the next SP-N number (next after the highest in `git log`). Never reuse a number.
  2. **Branch.** `sp<N>-<short-kebab-topic>` (e.g. `sp22-line-reconciliation`).
  3. **Spec path.** `docs/superpowers/specs/YYYY-MM-DD-cyclone-<topic>-design.md`. Status header: `Draft, pending user review`.
  4. **Plan path.** `docs/superpowers/plans/YYYY-MM-DD-cyclone-<topic>.md`. Header per writing-plans skill.
  5. **Commit prefix.** `feat(sp<N>): …`, `docs(spec): …`, `docs(plan): …`, `merge: SP<N> … into main`.
  6. **PR title.** `SP<N> <Topic>` (matches commit history).
  7. **Merge shape.** Single atomic merge commit into `main` after review; no squash, no rebase.
 - `## Patterns` — copy-pasteable skeleton for the spec header (Date / Status / Branch / Scope) and the plan header (per writing-plans).
 - `## Anti-patterns` — at least these:
  - Don't skip the spec ("it's a small fix"). Small fixes still get a 3-line spec when they introduce a new numbered increment.
  - Don't squash the merge commit — the SP-N merge commit is the audit trail.
  - Don't put code in the spec — the spec is the *what*, the plan is the *how*.
 - `## Related skills` — references to `cyclone-tests` (every spec mentions test impact), `cyclone-edi` / `cyclone-tail` / `cyclone-store` / `cyclone-api-router` / `cyclone-frontend-page` / `cyclone-cli` (each spec touches one or more of these), and the upstream `superpowers:brainstorming` / `superpowers:writing-plans` global skills.
 Keep total under ~200 lines. Use real examples drawn from existing specs (e.g. SP9 multi-payer, SP14 5-lane Inbox) where they illustrate the convention.
 - [ ] **Step 4: Verify frontmatter and structure**
 ```bash
 head -5 .superpowers/skills/cyclone-spec/SKILL.md
 wc -l .superpowers/skills/cyclone-spec/SKILL.md
 grep -c "^## " .superpowers/skills/cyclone-spec/SKILL.md
 ```
 Expected: first 5 lines are the YAML frontmatter (start `---`, end `---`), ~150-200 lines total, exactly 5 `## ` sections (`When to use`, `Conventions`, `Patterns`, `Anti-patterns`, `Related skills`).
 - [ ] **Step 5: Commit**
 ```bash
 git add .superpowers/skills/cyclone-spec/SKILL.md
 git commit -m "feat(sp-skill-catalog): add cyclone-spec skill (SP-N flow)"
 ```
 ---
 ## Task 2: Phase 1, Skill 2 — `cyclone-tests`
 **Goal:** Codify the pytest + vitest fixture patterns so every later skill can ship its `## Anti-patterns` cleanly. Specifically: how to drop a prodfiles fixture into `backend/tests/fixtures/`, how to write a `.test.tsx` next to a page, how to keep tests deterministic.
 **Files:**
 - Create: `.superpowers/skills/cyclone-tests/SKILL.md`
 - [ ] **Step 1: Survey the existing fixture layout**
 ```bash
 ls backend/tests/fixtures/ | head -30
 ls backend/tests/fixtures/ | wc -l
 ls src/**/*.test.tsx src/**/*.test.ts 2>/dev/null | wc -l
 ```
 Expected: dozens of fixtures under `backend/tests/fixtures/`, dozens of `.test.ts(x)` siblings across `src/`. Record counts for the skill.
 - [ ] **Step 2: Sample one backend pytest and one frontend vitest to cite**
 ```bash
 ls backend/tests/fixtures/ | head -3
 echo "---"
 ls src/hooks/*.test.ts | head -3
 ```
 Pick the smallest/most-representative example from each side to cite in the skill's `## Patterns`.
 - [ ] **Step 3: Create the directory and write the SKILL.md**
 ```bash
 mkdir -p .superpowers/skills/cyclone-tests
 ```
 Frontmatter:
 ```yaml
 ---
 name: cyclone-tests
 description: "Cyclone pytest + vitest fixture patterns, prodfiles layout, backend/tests/fixtures/ conventions, .test.tsx sibling rule. Use when: adding a backend pytest case, adding a frontend vitest test, or wiring in a real-EDI prodfiles sample."
 ---
 ```
 Body sections (each must be present):
 - `## When to use` — 4 bullets: adding a backend test, adding a frontend test, dropping in a prodfiles fixture, debugging a flaky test.
 - `## Conventions` — at minimum:
  1. **Frontend sibling rule.** Every new file in `src/` that contains testable logic gets a `*.test.ts(x)` next to it. `useFoo.ts` → `useFoo.test.ts`.
  2. **Backend test location.** Tests live under `backend/tests/test_*.py`. Integration tests (FastAPI) follow `test_api_*.py`; pure-unit tests (parsers, validators) follow `test_<module>_*.py`.
  3. **Prodfiles drop-in.** Real EDI samples live under `docs/prodfiles/<source>/<edi>.txt`. To use one in a test: copy to `backend/tests/fixtures/<test-name>/<edi>.txt` and reference via the existing fixture helper (see `## Patterns`).
  4. **Determinism.** Use `freezegun` for date-sensitive backend tests; use `vi.useFakeTimers()` for time-sensitive frontend tests. Never rely on `datetime.now()` directly.
  5. **No network.** Tests must not hit the network. `httpx`/`requests` mocks live in `conftest.py` fixtures.
  6. **pytest collection.** Run `cd backend && python -m pytest tests/<file>::<name> -v` for the fastest feedback loop. Full suite is the merge gate.
 - `## Patterns` — three small copy-pasteable skeletons:
  - One pytest using `tmp_path` + a prodfiles fixture reference.
  - One vitest `*.test.ts` for a hook using `vi.useFakeTimers()`.
  - One vitest `*.test.tsx` for a component using `@testing-library/react` + `happy-dom`.
 - `## Anti-patterns` — at least:
  - Don't put frontend tests in `src/__tests__/` (legacy location, no longer used).
  - Don't reach into `docs/prodfiles/` directly from a test — copy to `backend/tests/fixtures/` so tests stay runnable when prodfiles is reorganized.
  - Don't use `sleep()` for timing — use the deterministic timer tools listed in Conventions.
 - `## Related skills` — references to all 7 other skills (every domain skill impacts tests) plus `superpowers:test-driven-development` upstream.
 Keep under ~250 lines (this is the most cross-cutting skill, so it's the largest).
 - [ ] **Step 4: Verify**
 ```bash
 head -5 .superpowers/skills/cyclone-tests/SKILL.md
 wc -l .superpowers/skills/cyclone-tests/SKILL.md
 grep -c "^## " .superpowers/skills/cyclone-tests/SKILL.md
 ```
 Expected: frontmatter present, 150–250 lines, 5 `## ` sections.
 - [ ] **Step 5: Commit**
 ```bash
 git add .superpowers/skills/cyclone-tests/SKILL.md
 git commit -m "feat(sp-skill-catalog): add cyclone-tests skill (fixture patterns)"
 ```
 ---
 ## Task 3: Phase 2, Skill 3 — `cyclone-edi`
 **Goal:** Codify Cyclone's EDI parser/validator conventions across 837P/835/999/270/271/277CA/TA1. Highest-leverage skill — 30 parsers, scattered validators, fixture sprawl.
 **Files:**
 - Create: `.superpowers/skills/cyclone-edi/SKILL.md`
 - Create: `.superpowers/skills/cyclone-edi/references/parsers.md`
 - [ ] **Step 1: Enumerate the parsers and validator rules**
 ```bash
 ls backend/src/cyclone/parsers/
 grep -rn "^def parse_" backend/src/cyclone/parsers/ | head -40
 grep -n "^R[0-9]" backend/src/cyclone/validator*.py 2>/dev/null | head -20
 ls backend/src/cyclone/ | grep -i valid
 ```
 Expected: ~30 parser modules, each exporting `parse_*`, plus `validator.py` and possibly `validator_835.py`. Record the R-codes (R200, R210, etc.) found.
 - [ ] **Step 2: Sample one parser to cite in the skill**
 Pick the smallest one (e.g. `parse_ta1.py` or `parse_999.py`) and read the first 30 lines. The skill's `## Patterns` section will reference its structure.
 - [ ] **Step 3: Create directories and write the SKILL.md + reference**
 ```bash
 mkdir -p .superpowers/skills/cyclone-edi/references
 ```
 Frontmatter:
 ```yaml
 ---
 name: cyclone-edi
 description: "Cyclone EDI parser/validator conventions (837P/835/999/270/271/277CA/TA1). Use when: adding or changing a parser, adding a validator rule (R200/R210/NPI Luhn/EIN/CAS), or mapping a new CAS adjustment reason code."
 ---
 ```
 Body sections:
 - `## When to use` — 4 bullets: adding a parser, adding a validator rule, wiring a new CAS code, debugging a parse failure on a prodfiles sample.
 - `## Conventions` — at minimum:
  1. **Parser signature.** Every parser module exports `parse(text: str) -> <TypedResult>` where `<TypedResult>` is a Pydantic model from `backend/src/cyclone/parsers/<edi>_models.py` (or co-located).
  2. **Segment walk.** Parsers consume `backend/src/cyclone/segments.py` helpers (`Segment`, `Loop`, `next_segment`) — do not parse raw text inline.
  3. **Validator rules.** Numbered (R200, R210, …) live in `backend/src/cyclone/validator.py` (or `validator_835.py` for 835-specific). Each rule is a function `_rule_R<n>_<name>` raising `ValidationError` with the R-code.
  4. **NPI / EIN / CAS.** Identity-format rules (NPI Luhn, EIN `XX-XXXXXXX`, CAS adjustment reason codes) live in dedicated modules (`npi.py`, etc.). Don't duplicate the format logic.
  5. **Prodfiles reuse.** When adding a parser for a new transaction type, ship at least one prodfiles fixture in `backend/tests/fixtures/<edi>/<sample>.txt`.
 - `## Patterns` — three skeletons:
  - A minimal `parse_<edi>.py` (using `segments.py`, exporting `parse(text)`).
  - A validator rule `_rule_R<n>_<name>(ctx) -> None`.
  - A test that uses a prodfiles fixture (`backend/tests/fixtures/<edi>/<sample>.txt`) and asserts `parse(text).foo == expected`.
 - `## Anti-patterns` — at least:
  - Don't re-parse raw X12 strings inside validators — always parse first, validate the typed result.
  - Don't bake payer-specific logic into the generic parser — payer variations live in `backend/src/cyclone/payers.py` or `<payer>_config.py`.
  - Don't add a validator rule without an R-code — the R-code is how the UI surfaces the error.
 - `## Related skills` — references to `cyclone-store` (writes the parsed result), `cyclone-api-router` (exposes it), `cyclone-tests` (fixture drop-in), `cyclone-cli` (the `cyc parse <file>` smoke command).
 Then write `references/parsers.md`: a flat table mapping each parser module to its transaction type, signature, primary fixtures, and any payer-specific variants. Keep under 80 lines.
 - [ ] **Step 4: Verify**
 ```bash
 head -5 .superpowers/skills/cyclone-edi/SKILL.md
 wc -l .superpowers/skills/cyclone-edi/SKILL.md
 wc -l .superpowers/skills/cyclone-edi/references/parsers.md
 grep -c "^## " .superpowers/skills/cyclone-edi/SKILL.md
 ```
 Expected: frontmatter present, SKILL.md ≤ 200 lines, references/parsers.md ≤ 80 lines, exactly 5 `## ` sections in SKILL.md.
 - [ ] **Step 5: Commit**
 ```bash
 git add .superpowers/skills/cyclone-edi/
 git commit -m "feat(sp-skill-catalog): add cyclone-edi skill (parser/validator conventions)"
 ```

 ## Task 4: Phase 2, Skill 4 — `cyclone-tail`
 **Goal:** Codify the live-tail wire format and the `useTailStream` + `useMergedTail` + per-resource hook triplet. Concrete drift risk — wire format is in the README but consumed across 3 page-hook pairs.
 **Files:**
 - Create: `.superpowers/skills/cyclone-tail/SKILL.md`
 - Create: `.superpowers/skills/cyclone-tail/references/wire-format.md`
 - [ ] **Step 1: Survey the live-tail surface**
 ```bash
 grep -rn "/stream" backend/src/cyclone/api_routers/ src/hooks/ 2>/dev/null | head -20
 ls src/hooks/use*Stream* src/hooks/use*MergedTail*
 ls src/hooks/use*Tail* 2>/dev/null
 grep -rn "snapshot_end\|x-ndjson" backend/src/cyclone/ src/ 2>/dev/null | head -10
 ```
 Expected: 3 `/api/<resource>/stream` endpoints, one `useTailStream.ts`, one `useMergedTail.ts`, multiple `use<X>Stream` consumers.
 - [ ] **Step 2: Read the wire-format spec in the README**
 ```bash
 grep -n -A 30 "Wire format" README.md | head -50
 ```
 This is the canonical definition; the skill will reference it. Record the line range for the `references/wire-format.md` cross-reference.
 - [ ] **Step 3: Create directories and write the SKILL.md + reference**
 ```bash
 mkdir -p .superpowers/skills/cyclone-tail/references
 ```
 Frontmatter:
 ```yaml
 ---
 name: cyclone-tail
 description: "Cyclone live-tail streaming wire format and the useTailStream / useMergedTail hook triplet. Use when: adding a new streaming list page, changing the wire format, debugging stalled/reconnecting state, or modifying the StatusPill behavior."
 ---
 ```
 Body sections:
 - `## When to use` — 4 bullets: adding a new streaming page, changing the wire format, debugging stalled/reconnecting, tuning heartbeat/stall timing.
 - `## Conventions` — at minimum:
  1. **Wire format.** Newline-delimited JSON. Line shapes: `{"type":"item","data":…}`, `{"type":"snapshot_end","data":{"count":N}}`, `{"type":"heartbeat","data":{"ts":…}}`, `{"type":"item_dropped","data":…}`, `{"type":"error","data":…}`. See `references/wire-format.md`.
  2. **Hook triplet.** Streaming pages consume three hooks: `useTailStream(url)` (raw stream state), `useMergedTail(items, events)` (combine initial fetch with live events), and a per-resource hook (`useClaims`, `useRemittances`, etc.) that wraps both.
  3. **Stall threshold.** 30s of total silence (heartbeat included) flips the connection to `stalled` and surfaces a `↻ Reconnect` button. Don't change this without updating the README's "Status pill" table.
  4. **Snapshot first.** Every stream must emit the current snapshot before any live `item` events. The `snapshot_end` line is the marker the UI uses to flip `StatusPill` from `connecting` to `live`.
  5. **Content-Type.** `application/x-ndjson`. Never `application/json` for a stream endpoint.
 - `## Patterns` — three skeletons:
  - A `useFoo.ts` page-hook skeleton (TanStack Query initial fetch + tail subscription).
  - A new backend `/api/foo/stream` endpoint signature.
  - A `StatusPill` consumer wiring.
 - `## Anti-patterns` — at least:
  - Don't hand-roll `fetch` + `ReadableStream` parsing in a page — go through `useTailStream` so reconnect/stall handling is consistent.
  - Don't change the wire format on one endpoint without updating the other two — they share the parser in `src/lib/tail-stream.ts`.
  - Don't emit `item` events before `snapshot_end` — the UI will duplicate rows.
 - `## Related skills` — references to `cyclone-frontend-page` (page-level wiring), `cyclone-api-router` (the `/api/<resource>/stream` endpoint), `cyclone-store` (the event contract that drives the stream), `cyclone-tests` (`.test.ts` siblings on every hook in this skill).
 Then write `references/wire-format.md`: copy the relevant README section (with attribution) and add a per-line field reference table (which fields are required, which are optional, parser tolerance). Keep under 80 lines.
 - [ ] **Step 4: Verify**
 ```bash
 head -5 .superpowers/skills/cyclone-tail/SKILL.md
 wc -l .superpowers/skills/cyclone-tail/SKILL.md
 wc -l .superpowers/skills/cyclone-tail/references/wire-format.md
 grep -c "^## " .superpowers/skills/cyclone-tail/SKILL.md
 ```
 Expected: frontmatter present, SKILL.md ≤ 200 lines, wire-format.md ≤ 80 lines, 5 `## ` sections.
 - [ ] **Step 5: Commit**
 ```bash
 git add .superpowers/skills/cyclone-tail/
 git commit -m "feat(sp-skill-catalog): add cyclone-tail skill (live-tail wire format)"
 ```

 ## Task 5: Phase 3, Skill 5 — `cyclone-store`
 **Goal:** Codify the store write-paths, the pubsub event contract, and the SP21 store-split boundary map. Aligns with the SP21 store split currently in plan stage — the skill codifies the new boundaries as they land.
 **Files:**
 - Create: `.superpowers/skills/cyclone-store/SKILL.md`
 - [ ] **Step 1: Read SP21 plan to learn the new module boundaries**
 ```bash
 cat docs/superpowers/plans/2026-06-21-cyclone-store-split.md | head -80
 ```
 Record the module list (`batches`, `inbox`, `acks`, etc.) for use in the skill.
 - [ ] **Step 2: Survey the current pubsub surface**
 ```bash
 grep -rn "_written\|_recorded" backend/src/cyclone/pubsub.py | head -20
 grep -rn "publish\|subscribe" backend/src/cyclone/store.py | head -10
 ```
 Expected: at least 3 event types — `claim_written`, `remittance_written`, `activity_recorded`. Record exact names.
 - [ ] **Step 3: Create the directory and write the SKILL.md**
 ```bash
 mkdir -p .superpowers/skills/cyclone-store
 ```
 Frontmatter:
 ```yaml
 ---
 name: cyclone-store
 description: "Cyclone store write-paths, the pubsub event contract (claim_written / remittance_written / activity_recorded), and the SP21 store-split boundary map. Use when: touching store.py, adding a new entity, wiring a new write event, or splitting a store module."
 ---
 ```
 Body sections:
 - `## When to use` — 4 bullets: adding a new entity, wiring a new write event, debugging a write-path issue, splitting a store module.
 - `## Conventions` — at minimum:
  1. **All writes go through `CycloneStore`.** Route handlers and parsers must not write directly to the ORM session.
  2. **Every write publishes an event.** The event name matches the entity: `claim_written`, `remittance_written`, `activity_recorded`. New entities get `<entity>_written` (or `_recorded` for non-canonical rows).
  3. **Snapshot shape.** Each entity has a Pydantic serializer in `backend/src/cyclone/store/ui.py` (or its post-SP21 equivalent). The serializer is the single source of truth for what the frontend sees.
  4. **SP21 boundaries.** Post-split, each domain lives in its own module (`batches`, `inbox`, `acks`, …). Cross-module writes go through `CycloneStore` facade methods, not direct module access.
  5. **No business logic in route handlers.** A route handler validates input, calls `store.<method>(...)`, publishes the event, returns the serialized result. Anything more belongs in the store or a parser.
 - `## Patterns` — three skeletons:
  - A `CycloneStore` write method (`def add_foo(self, foo: Foo) -> FooRecord`).
  - An event publication in `pubsub.py`.
  - A new `<entity>_written` handler test that asserts both the row and the event.
 - `## Anti-patterns` — at least:
  - Don't read directly from the ORM in a route handler — go through the snapshot serializer.
  - Don't introduce a new event name without updating the subscriber list (currently `api.py` and `api_routers/`).
  - Don't merge a write method with its event publication into separate places — they live next to each other so reviewers see both.
 - `## Related skills` — references to `cyclone-edi` (the parsed result lands here), `cyclone-api-router` (the route that calls the store), `cyclone-tail` (the event drives the stream), `cyclone-tests` (write-path tests).
 Keep under ~200 lines. No `references/` needed unless the boundary map grows.
 - [ ] **Step 4: Verify**
 ```bash
 head -5 .superpowers/skills/cyclone-store/SKILL.md
 wc -l .superpowers/skills/cyclone-store/SKILL.md
 grep -c "^## " .superpowers/skills/cyclone-store/SKILL.md
 ```
 Expected: frontmatter present, ≤ 200 lines, 5 `## ` sections.
 - [ ] **Step 5: Commit**
 ```bash
 git add .superpowers/skills/cyclone-store/SKILL.md
 git commit -m "feat(sp-skill-catalog): add cyclone-store skill (write paths + event contract)"
 ```
 ---
 ## Task 6: Phase 3, Skill 6 — `cyclone-api-router`
 **Goal:** Codify FastAPI router conventions — `api_routers/`, `api_helpers.py` reuse, response shapes, error envelopes. Pairs with `cyclone-store`.
 **Files:**
 - Create: `.superpowers/skills/cyclone-api-router/SKILL.md`
 - [ ] **Step 1: Survey the existing router layout**
 ```bash
 ls backend/src/cyclone/api_routers/
 grep -l "APIRouter" backend/src/cyclone/api_routers/*.py
 head -30 backend/src/cyclone/api_helpers.py
 ```
 Record the router filenames and which helpers exist in `api_helpers.py`.
 - [ ] **Step 2: Sample one router**
 Pick the smallest existing router (likely `acks.py` or `ta1_acks.py`) and read the first 50 lines. The skill's `## Patterns` section will reference its structure.
 - [ ] **Step 3: Create the directory and write the SKILL.md**
 ```bash
 mkdir -p .superpowers/skills/cyclone-api-router
 ```
 Frontmatter:
 ```yaml
 ---
 name: cyclone-api-router
 description: "Cyclone FastAPI router conventions (api_routers/, api_helpers.py, response shapes, error envelopes). Use when: adding or changing an HTTP endpoint, splitting a route out of api.py, or wiring a new helper into api_helpers.py."
 ---
 ```
 Body sections:
 - `## When to use` — 4 bullets: adding an endpoint, splitting a route, adding a helper, defining an error response.
 - `## Conventions` — at minimum:
  1. **No new top-level routes in `api.py`.** Every endpoint lives in `backend/src/cyclone/api_routers/<topic>.py` as an `APIRouter`.
  2. **Reuse `api_helpers.py`.** Common response shapes, error envelopes, and parsing helpers live there. Don't duplicate them in a router.
  3. **Response shape.** Every successful response is a Pydantic model. Errors use the shared `ErrorEnvelope` (from `api_helpers.py`) with `code` and `message`.
  4. **Mounting.** Routers are mounted in `api.py` with their prefix; keep prefix naming consistent (`/api/<resource>`).
  5. **Streaming endpoints.** Use `StreamingResponse(media_type="application/x-ndjson")` — see `cyclone-tail` for the wire format.
  6. **Tests.** Every new endpoint gets a `test_api_<topic>_<verb>.py` test under `backend/tests/`.
 - `## Patterns` — three skeletons:
  - A new `APIRouter` skeleton (`router = APIRouter(prefix="/api/foo", tags=["foo"])`).
  - A `get_one` / `get_list` / `post_one` trio with Pydantic response models.
  - An error envelope usage example.
 - `## Anti-patterns` — at least:
  - Don't import from `cyclone.api` into a router — the dependency runs the other way.
  - Don't return raw dicts — always Pydantic.
  - Don't bypass `CycloneStore` to query the ORM directly — see `cyclone-store`.
 - `## Related skills` — references to `cyclone-store` (most routes call store methods), `cyclone-tail` (streaming endpoints), `cyclone-edi` (parse endpoints), `cyclone-tests` (endpoint tests).
 Keep under ~200 lines.
 - [ ] **Step 4: Verify**
 ```bash
 head -5 .superpowers/skills/cyclone-api-router/SKILL.md
 wc -l .superpowers/skills/cyclone-api-router/SKILL.md
 grep -c "^## " .superpowers/skills/cyclone-api-router/SKILL.md
 ```
 Expected: frontmatter present, ≤ 200 lines, 5 `## ` sections.
 - [ ] **Step 5: Commit**
 ```bash

 ## Task 7: Phase 4, Skill 7 — `cyclone-frontend-page`
 **Goal:** Codify the React page-component pattern — TanStack Query, `use<X>` hook, drawer, URL state, `.test.tsx` sibling. Generalizes what `cyclone-tail` already covers.
 **Files:**
 - Create: `.superpowers/skills/cyclone-frontend-page/SKILL.md`
 - [ ] **Step 1: Survey the page layout**
 ```bash
 ls src/pages/
 echo "---"
 ls src/components/ui/ | head -20
 ```
 Record the page list and which shadcn-style UI components are in `src/components/ui/`.
 - [ ] **Step 2: Sample one page to cite**
 ```bash
 head -50 src/pages/Claims.tsx
 ```
 Use this in the skill's `## Patterns` to show the canonical page structure.
 - [ ] **Step 3: Create the directory and write the SKILL.md**
 ```bash
 mkdir -p .superpowers/skills/cyclone-frontend-page
 ```
 Frontmatter:
 ```yaml
 ---
 name: cyclone-frontend-page
 description: "Cyclone React page conventions (TanStack Query, use<X> hook, drawer, URL state, .test.tsx sibling, Layout / PageHeader / Sidebar). Use when: adding a new page, refactoring an existing one, or wiring a drawer into a page."
 ---
 ```
 Body sections:
 - `## When to use` — 4 bullets: adding a new page, refactoring an existing page, wiring a drawer, sharing state via URL.
 - `## Conventions` — at minimum:
  1. **Page shape.** Every page in `src/pages/<Name>.tsx` exports a default `function <Name>()`. It uses `<Layout>`, sets a `<PageHeader>`, and renders a table or list.
  2. **Data hook.** Each page pairs with a `use<X>` hook in `src/hooks/use<X>.ts` that returns `{ data, isLoading, error, ...tail }`. Pages do not call `fetch` directly.
  3. **Tail.** If the page shows live data, it consumes the tail-stream pattern via `cyclone-tail`. The hook, not the page, owns the streaming subscription.
  4. **Drawer.** Drawers (e.g. `ClaimDrawer`, `RemitDrawer`) live in `src/components/<DrawerName>/` and are wired via `useDrawerUrlState` so the URL reflects open state.
  5. **Tests.** Every page gets a `src/pages/<Name>.test.tsx` sibling. Every hook gets a `src/hooks/use<X>.test.ts` sibling.
  6. **UI primitives.** Use Radix-backed components from `src/components/ui/`. Don't pull in new UI libraries without discussion.
  7. **Routing.** Pages register their route in `src/App.tsx`. Lazy-load if the page is heavy.
 - `## Patterns` — three skeletons:
  - A minimal `Claims.tsx`-style page (Layout + PageHeader + table + drawer).
  - A `use<X>` hook skeleton (TanStack Query + tail).
  - A drawer component skeleton with `useDrawerUrlState`.
 - `## Anti-patterns` — at least:
  - Don't `fetch` from inside a page component — go through the hook.
  - Don't open a drawer via local component state — use `useDrawerUrlState` so deep-links work.
  - Don't put domain logic in JSX — extract to the hook or a pure helper in `src/lib/`.
 - `## Related skills` — references to `cyclone-tail` (live-data pages), `cyclone-api-router` (the endpoints pages call), `cyclone-tests` (page + hook tests), `cyclone-edi` (pages that show parsed EDI content).
 Keep under ~200 lines.
 - [ ] **Step 4: Verify**
 ```bash
 head -5 .superpowers/skills/cyclone-frontend-page/SKILL.md
 wc -l .superpowers/skills/cyclone-frontend-page/SKILL.md
 grep -c "^## " .superpowers/skills/cyclone-frontend-page/SKILL.md
 ```
 Expected: frontmatter present, ≤ 200 lines, 5 `## ` sections.
 - [ ] **Step 5: Commit**
 ```bash
 git add .superpowers/skills/cyclone-frontend-page/SKILL.md
 git commit -m "feat(sp-skill-catalog): add cyclone-frontend-page skill (React page conventions)"
 ```

 ## Task 8: Phase 4, Skill 8 — `cyclone-cli`
 **Goal:** Codify the CLI subcommand conventions in `cli.py` — argparse style, exit codes, smoke-test patterns. Last because nothing else depends on it.
 **Files:**
 - Create: `.superpowers/skills/cyclone-cli/SKILL.md`
 - [ ] **Step 1: Survey the existing CLI**
 ```bash
 grep -n "add_parser\|sub_parsers\|set_defaults" backend/src/cyclone/cli.py | head -20
 grep -n "sys.exit\|return [0-9]\|return 1\|return 2" backend/src/cyclone/cli.py | head -10
 ```
 Record the subcommand list and exit-code conventions.
 - [ ] **Step 2: Sample one subcommand**
 Pick the smallest (likely `validate`) and read its 20-30 lines. The skill's `## Patterns` will reference its structure.
 - [ ] **Step 3: Create the directory and write the SKILL.md**
 ```bash
 mkdir -p .superpowers/skills/cyclone-cli
 ```
 Frontmatter:
 ```yaml
 ---
 name: cyclone-cli
 description: "Cyclone CLI subcommand conventions (cli.py, serve/parse/backup/rotate-key/validate, argparse style, exit codes, smoke tests). Use when: adding a CLI subcommand, changing exit codes, or working on operator-facing commands."
 ---
 ```
 Body sections:
 - `## When to use` — 4 bullets: adding a subcommand, changing exit codes, adding a smoke test, wiring a security-sensitive command (key rotation, backup).
 - `## Conventions` — at minimum:
  1. **Subcommand shape.** Every subcommand is a function `cmd_<name>(args) -> int` in `cli.py`. The `main()` parser dispatches via `set_defaults(func=...)`.
  2. **Argparse style.** Use `argparse.ArgumentParser` sub-parsers. Long-form flags (`--rotate-key`) preferred over positional for safety.
  3. **Exit codes.** `0` = success, `1` = user error (bad input, missing file), `2` = operator error (DB locked, key missing), `3` = security error (auth fail, key mismatch). Document in `cmd_<name>` docstring.
  4. **Smoke test.** Every new subcommand gets a `backend/tests/test_cli_<name>.py` test using `subprocess.run` against the installed `cyc` entrypoint.
  5. **Security-sensitive commands.** Key rotation (`cyc rotate-key`), backup (`cyc backup`), and any command touching `secrets.py` requires a `--confirm` flag and a dry-run path.
 - `## Patterns` — three skeletons:
  - A `cmd_<name>(args)` function with `argparse` setup.
  - A `subprocess.run` smoke test.
  - A `--confirm` / `--dry-run` pattern for security-sensitive commands.
 - `## Anti-patterns` — at least:
  - Don't `sys.exit()` from inside a subcommand — return the int and let `main()` exit.
  - Don't print to stdout for errors — use `logging` (or `print(..., file=sys.stderr)` for top-level fatal errors).
  - Don't add a subcommand without a smoke test in `backend/tests/test_cli_<name>.py`.
 - `## Related skills` — references to `cyclone-store` (most subcommands touch the store), `cyclone-api-router` (`cyc serve` runs the FastAPI app), `cyclone-edi` (`cyc parse <file>`), `cyclone-tests` (CLI smoke tests).
 Keep under ~200 lines.
 - [ ] **Step 4: Verify**
 ```bash
 head -5 .superpowers/skills/cyclone-cli/SKILL.md
 wc -l .superpowers/skills/cyclone-cli/SKILL.md
 grep -c "^## " .superpowers/skills/cyclone-cli/SKILL.md
 ```
 Expected: frontmatter present, ≤ 200 lines, 5 `## ` sections.
 - [ ] **Step 5: Commit**
 ```bash
 git add .superpowers/skills/cyclone-cli/SKILL.md
 git commit -m "feat(sp-skill-catalog): add cyclone-cli skill (CLI conventions)"
 ```
 ---
 ## Task 9: Final — README catalog section
 **Goal:** Advertise the catalog to human readers and to AI agents reading the README on first contact.
 **Files:**
 - Modify: `README.md` (add a "Skills" section near the top)
 - [ ] **Step 1: Find a good insertion point**
 ```bash
 grep -n "^## " README.md | head -20
 ```
 Pick a sensible location — typically after the existing "Install" or "Dev" section.
 - [ ] **Step 2: Add the catalog section**
 Add a new `## Skills` section listing all 8 skills with a one-line description each. Example:
 ```markdown
 ## Skills
 Cyclone ships 8 project-scoped AI-assistant skills under
 [`.superpowers/skills/`](.superpowers/skills/). Each one codifies the
 conventions for a major subsystem so the next contributor (human or
 AI) gets the lay of the land automatically.
 | Skill | Owns |
 |-------|------|
 | [`cyclone-spec`](.superpowers/skills/cyclone-spec/SKILL.md) | The SP-N spec → plan → implement → merge flow. |
 | [`cyclone-tests`](.superpowers/skills/cyclone-tests/SKILL.md) | pytest + vitest fixture patterns, prodfiles drop-in. |
 | [`cyclone-edi`](.superpowers/skills/cyclone-edi/SKILL.md) | EDI parser/validator conventions (837P/835/999/270/271/277CA/TA1). |
 | [`cyclone-tail`](.superpowers/skills/cyclone-tail/SKILL.md) | Live-tail streaming wire format and the hook triplet. |
 | [`cyclone-store`](.superpowers/skills/cyclone-store/SKILL.md) | Store write-paths, pubsub event contract, SP21 split map. |
 | [`cyclone-api-router`](.superpowers/skills/cyclone-api-router/SKILL.md) | FastAPI router conventions (`api_routers/`, `api_helpers.py`). |
 | [`cyclone-frontend-page`](.superpowers/skills/cyclone-frontend-page/SKILL.md) | React page conventions (TanStack Query, drawer, URL state). |
 | [`cyclone-cli`](.superpowers/skills/cyclone-cli/SKILL.md) | CLI subcommand conventions (`cli.py`, exit codes, smoke tests). |
 Skills auto-load by description match — no slash command needed.
 ```
 - [ ] **Step 3: Verify the section reads cleanly**
 ```bash
 grep -n -A 16 "^## Skills" README.md
 ```
 Expected: the section renders with all 8 rows and the trailing usage note.
 - [ ] **Step 4: Commit**
 ```bash
 git add README.md
 git commit -m "docs(readme): add Skills section linking the 8-skill catalog"
 ```
 ---
 ## Self-review (run after writing the plan, before executing)
 - [ ] **Spec coverage.** Skim each section of `docs/superpowers/specs/2026-06-21-cyclone-skill-catalog-design.md`. Confirm:
  - Spec §"The catalog" → Tasks 1-8 each create the matching skill. ✅
  - Spec §"Per-skill structure" → enforced by the shared template locked in Task 0. ✅
  - Spec §"Loading & cross-references" → every Task has a `## Related skills` section. ✅
  - Spec §"Build order / phasing" → Phase order = Task order (1-2 foundations, 3-4 domain, 5-6 backend, 7-8 frontend+CLI). ✅
  - Spec §"Verification" → covered by verification steps in each task + Task 9 README addition. ✅
 - [ ] **Placeholder scan.** No "TBD" / "TODO" / "implement later" in the plan. Each task's body content is specified (frontmatter exact, sections listed, key bullets enumerated).
 - [ ] **Type / name consistency.**
  - Skill names: `cyclone-spec`, `cyclone-tests`, `cyclone-edi`, `cyclone-tail`, `cyclone-store`, `cyclone-api-router`, `cyclone-frontend-page`, `cyclone-cli`. Same in every task. ✅
  - Commit prefix: `feat(sp-skill-catalog): …` everywhere. ✅
  - Section names: `## When to use`, `## Conventions`, `## Patterns`, `## Anti-patterns`, `## Related skills`. Same in every task. ✅
 Plan passes self-review.

Tyler	63b2870f6e	docs: surface SP9-SP13 in README + endpoint reference The README only documented up to SP8 even though SP9-SP13 (multi-payer + multi-NPI + SFTP stub, 277CA + Payer-Rejected lane, tamper-evident audit log, optional SQLCipher encryption, paramiko SFTP wire-up) are all merged into main. This brings the README back in line with the codebase: - Inbox section: bump lane count from four to five, add the payer_rejected lane (and its monotonic stamping contract). - Add a Multi-Payer, Multi-NPI & Clearhouse section (SP9): the providers / payers / payer_configs / clearhouse tables, the config/payers.yaml loader, the new config + clearhouse endpoints. - Add a 277CA Claim Acknowledgment section (SP10): parse-277ca + 277ca-acks, the Payer-Rejected stamp semantics. - Add a Tamper-Evident Audit Log section (SP11): hash-chained audit_log, the verify endpoint. - Add an Encryption at Rest section (SP12): Keychain-stored SQLCipher key, transparent fallback to plain SQLite. - Add an SFTP Wire-Up (paramiko) section (SP13): the production submit path and the file-naming template. - Persistence section: link to the Encryption at Rest section. - Roadmap: bump shipped sub-projects to 2-13, add a one-line pointer to the completeness review for the honest industry-gap accounting. - Project layout: add api_helpers, db_crypto, audit_log, the new inbox_* modules, providers/payers/secrets, the new test files, and the config/ + docs/reviews/ + docs/superpowers/specs/ tree. - backend/README: refresh the endpoint table to include the parse-999/parse-ta1/parse-277ca/eligibility/clearhouse/admin surface; point at the root README for the full route list.	2026-06-21 00:10:50 -06:00
