The auto-linker closes the operator gap where every inbound 999 /
277CA / TA1 ack was persisted but never linked back to the claim it
acknowledges. Five pure helpers land in cyclone/claim_acks.py:
- lookup_claims_for_ack_set_response — D10 two-pass join. Primary is
Batch.envelope.control_number (== source 837 ST02 for Gainwell
batches); fallback is Claim.patient_control_number. Pass 1 wins,
the two paths cannot both fire.
- apply_999_acceptances — walks parsed_999.set_responses, emits one
ClaimAck per AK2 per matched claim (one-ack-to-many supported).
Both accepted AND rejected AK2s link; per-AK2 granularity.
- apply_277ca_acks — same shape for parsed_277ca.claim_statuses.
STC category code carried on the link row's
set_accept_reject_code so the UI can render the lane inline
without re-parsing raw_json.
- apply_ta1_envelope_link — envelope-level link. The link row has
claim_id NULL + batch_id populated (the spec's batch-level TA1
trace). Sender/receiver matching is delegated to a closure the
caller supplies.
- link_manual — manually link an ack to a claim. Used by the new
/api/acks/{kind}/{id}/match-claim endpoint. Idempotent.
All five helpers are pure (callers own the session); idempotent via
the partial unique index ux_claim_acks_dedup (helpers pre-check to
avoid IntegrityError log noise on re-ingest); flush-only (callers
commit).
14 of 15 named tests pass (the facade surface check belongs in
Phase 3 once store/claim_acks.py lands).
Steps 2.1/2.2/2.3/2.4/2.5 of the SP28 implementation plan.
The claim_acks join table is the durable record of which inbound
999 / 277CA / TA1 ack acknowledged which claim (or, for TA1, which
originating 837 Batch). One row per AK2 set-response / ClaimStatus
/ envelope. The match granularity is per-AK2 so the operator can
answer 'which claims does this ack acknowledge?' with a single
SELECT and so the ClaimDrawer panel can show per-segment accept /
reject status without re-parsing raw_json.
Schema mirrors spec §3.1:
- claim_id NULLable + batch_id NULLable (TA1 envelope links land
on batch_id; CHECK enforces at least one populated)
- unique partial index ux_claim_acks_dedup enforces idempotent
re-ingest of the same 999 file
- set_control_number stores the value the upstream ack ACTUALLY
CARRIED (== source 837 ST02 for Gainwell batches) for orphan
traceability — the link survives even when the join had to fall
back from ST02 to PCN matching
Mirrored on the ORM via Index(..., sqlite_where=text(...)) so
Base.metadata.create_all (the test-time safety net) emits the same
partial-unique constraint as the migration.
Step 1.1/1.2/1.3 of the SP28 implementation plan.
Single source of truth for the VITE_API_BASE_URL prefix logic. Both
auth/api and lib/api imported the same BASE_URL const; promote joinUrl
to a shared exported helper so future endpoints don't drift on the
trailing-slash normalization.
The original SP28 spec assumed `Claim.patient_control_number == 999.set_control_number`.
Empirically that's wrong: Gainwell's 999 echoes the source 837's ST02, not its
CLM01, and TOC's billing software fills them differently. Measured against
prod on 2026-07-02: the PCN join matches 0 / 1,398 acks.
Fix: two-pass join. Primary is `Batch.envelope.control_number (== 837 ST02)
→ claims via batch_id`; fallback is `Claim.patient_control_number` (for
senders that fill CLM01 == ST02). Coverage after fix: 727 / 1,398 (52%);
the remaining 671 are real orphans (ST02=0001 placeholder, no matching 837
batch in our DB).
Spec adds D10 + a critical-correction paragraph at the top of §1. Plan
gains the `lookup_claims_for_ack_set_response` pure helper, the
`batch_envelope_index()` store method, and three new tests covering the
two-pass join + the false-positive guard + the one-ack-to-many case.
The 1,156 accepted acks were burying the 5 rejections — the operator
had to scroll the whole table to find them. Two changes:
1. Sidebar '999 ACKs' nav item gets a warning-toned badge showing
the total rejected segment count from aggregates.rejected_count
(mirrors the Reconciliation unmatched badge pattern). One number,
visible from any page.
2. Acks page table now sorts rejected rows to the top, then
newest-id-first. All 5 rejections fit on page 1 since they're a
tiny fraction of the total — no pagination needed.
New files:
- src/hooks/useAckStats.ts (lightweight aggregates-only fetch)
- src/hooks/useAckStats.test.tsx (2 tests)
- src/components/Sidebar.test.tsx (3 tests)
Pre-existing baseline: 10 frontend failures (api.test.ts exportBatch837,
tail-stream.test.ts acks/ta1_acks targeting, Inbox/InboxHeader copy).
Unchanged.
The SFTP poller was off by default in the production container —
operators had to POST /api/admin/scheduler/start manually after every
restart, which they were not doing. As a result the inbound 999 / 277CA
queue fell 7+ days behind in early July 2026 (scheduler.poll_count=0
in the live container since deploy).
Mirrors the existing CYCLONE_BACKUP_AUTOSTART=1 entry.
Note: there is a separate bug where scheduler._tick_impl's alphabetical
list_inbound hangs after ~30s on mft.gainwelltechnologies.com (TCP +
auth + first SFTP channel works, but the full alphabetic scan times
out). The pull-inbound CLI's date-filtered path works fine — SP to
follow.
Wires the live-tail triplet (useTailStream + useMergedTail +
<TailStatusPill>) into the Acks page so 999 and TA1 acknowledgments
appear the moment the SFTP poller (or a manual upload) lands them in
the database — no more 'no tracking is being updated'.
Backend changes
---------------
* store/acks.py: add_ack / add_ta1_ack / add_277ca_ack now publish
ack_received / ta1_ack_received / two77ca_ack_received from inside
the store after commit. Failures don't roll back the row.
* store/ui.py: new home for to_ui_ack / to_ui_ta1_ack / to_ui_two77ca_ack
so the live-tail payload matches the list endpoint shape byte-for-byte.
* api_routers/acks.py + api_routers/ta1_acks.py: new /api/acks/stream
and /api/ta1-acks/stream NDJSON endpoints following the live-tail
wire format used by /api/claims/stream, /api/remittances/stream,
and /api/activity/stream (snapshot + snapshot_end + live events +
heartbeat + clean disconnect).
* api.py: parse-999 / parse-ta1 / parse-277ca endpoints thread
request.app.state.event_bus into the store on write.
* handlers/handle_*.py: dropped the event_bus kwarg; the publish
path is now store-only, not handler-driven.
Frontend changes
----------------
* lib/tail-stream.ts: TailResource widened to include acks + ta1_acks.
* store/tail-store.ts: acks + ta1Acks slices, addAck + addTa1Ack
setters, matching reset cases. evictOldest is generic over
(K extends string|number, V) so both keyed-by-id flavors share it.
* hooks/useTailStream.ts: dispatch routes acks / ta1_acks items into
the matching store slices.
* hooks/useMergedTail.ts: generic constraint widened to
T extends { id: string | number }, dedup normalizes via String(id)
so numeric ids compare correctly.
* pages/Acks.tsx: opens both streams + renders two <TailStatusPill>
components (one in the 999 hero, one in the TA1 section).
Verification
------------
* Backend: 1191 pass, 1 pre-existing test pollution failure (also
fails on main, passes in isolation, unrelated to SP25).
* Frontend: 535 pass, 10 pre-existing failures in Inbox / Upload /
Receipt / InboxHeader tests (all verified to fail the same way on
main).
* TypeScript: zero new SP25 errors. Pre-existing Upload / Inbox
errors match main.
Per the SP-N increment flow: no squash, no rebase. The merge commit
is the record of the increment landing.
Three small follow-ups after the live-tail triplet wired up:
* evictOldest is now generic over (K extends string|number, V) so
the addAck / addTa1Ack call sites don't need a type assertion.
* Acks.test.tsx no longer spreads importOriginal() — TypeScript
was choking on the inferred 'unknown' from the mock factory.
Use the same ApiError / mock shape that Claims.test.tsx uses.
* tail-stream.test.ts guards the optional gen.return() with
so strict mode TS2722 stops complaining about possibly-undefined.
The 999 register opens /api/acks/stream via useTailStream("acks"),
merges the snapshot + tail through useMergedTail("acks", ...) so
new rows appear without a manual refresh, and surfaces the
connection state via <TailStatusPill> in the hero. The TA1 section
gets the same triplet against /api/ta1-acks/stream.
Both pills sit in the page header so the operator can see at a
glance whether the live-tail connection is healthy, without having
to open the drawer or refresh the page. A stalled/error stream
shows a Reconnect button inline.
The Acks test mock adds useTailStream at the module level so the
page renders without opening a real fetch. New test asserts both
TailStatusPills mount in the page tree.
The Acks page needs two merge hooks (one per ack flavor) and both
shapes use numeric database ids rather than the string ids that
Claim/Remittance/Activity use. The generic constraint widens to
`T extends { id: string | number }` and the dedup Set normalizes
to String(id) so a base item with id=2 and a tail item with id=2
collide correctly.
Adds two switch cases that mirror the claims/remittances keyed-by-id
pattern: iterate the order array, look up the matching value in the
dict, drop undefined holes defensively.
Two tests assert the new slices order by their order arrays and dedup
against base items.
The Acks page mounts two streams (useTailStream("acks") and
useTailStream("ta1_acks")) — the dispatcher now routes their item
events into the matching store slices (addAck / addTa1Ack) the same
way the claims / remittances / activity cases already do.
Two new tests assert that an acks item lands in the acks slice (not
in claims) and a ta1_acks item lands in the ta1Acks slice (not in
acks) — i.e. the routing is exclusive, so a payload keyed by id 7
won't bleed across the two ack tables.
The Acks page needs the same live-tail triplet as Claims/Remittances/
Activity. Both Ack and Ta1Ack have stable numeric ids from the
database row, so they get the keyed-by-id treatment (first write
wins, FIFO-capped at TAIL_CAP) — same shape as the claims and
remittances slices, not the append-only activity array.
Adds addAck, addTa1Ack, ackOrder, ta1AckOrder, and the matching
reset cases for the new 'acks' / 'ta1_acks' TailResource kinds.
evictOldest is now generic over T so the same helper covers the
two new keyed-by-id slices without duplication.
The Acks page needs the same live-tail triplet (useTailStream +
useMergedTail + TailStatusPill) that Claims/Remittances/Activity
already use. The first step is widening the TailResource union so
streamTail("acks") and streamTail("ta1_acks") are valid and the
URL falls out as /api/acks/stream and /api/ta1-acks/stream.
Two new tests assert the URL targets the new backend endpoints.
Adds two streaming endpoints that match the live-tail wire format
established by /api/claims/stream, /api/remittances/stream, and
/api/activity/stream:
* /api/acks/stream — subscribes to ack_received
* /api/ta1-acks/stream — subscribes to ta1_ack_received
Both yield a snapshot of existing rows (newest first, capped by the
`limit` query param), then a `snapshot_end` line, then forward
live events from the bus. They are registered before the
/{ack_id} path-param endpoints so the literal `stream` segment
isn't matched as an id.
Tests use the same direct-coroutine pattern as test_api_stream_live.py
because httpx.ASGITransport buffers the response body and never
delivers a disconnect message — iterating body_iterator directly
with body_iterator.aclose() simulates a client disconnect.
Splits the 2,995-LOC backend/src/cyclone/store.py into a
cyclone/store/ subpackage (13 sibling modules + __init__.py
facade) with no public API change. Adds dashboard_kpis,
check_matched_pair_drift, _claim_state_str (SP27) into the
right homes, and surfaces 3 private helpers (_claim_status_from_validation,
_persist_835_remit, _remittance_835_row) from the facade for
existing test imports.
Spec: docs/superpowers/specs/2026-06-21-cyclone-store-split-design.md
Plan: docs/superpowers/plans/2026-06-29-cyclone-store-split-resume.md
Tests at baseline: 1 failed (pre-existing isolation flake),
1176 passed, 10 skipped.
- write.py: drop orphan run_reconcile() — no callers, and the
pre-split store.py never had it. (The CycloneStore class already
has _publish_events_sync + _sync_publish delegations; the spec's
mention of _run_reconcile was a doc drift from the 2026-06-21
plan, not a real requirement.)
- ui.py: drop duplicate _provider_orm_to_dict + _payer_orm_to_dict
(canonical copies live in providers.py and are the only ones used;
the ui.py copies were accidental duplicates from the split).
- orm_builders.py: drop orphan _cas_adjustment_row() — never called;
_persist_835_remit() builds CAS rows inline.
- __init__.py: prune 30+ unused top-level imports and 9 unused
re-exports. The facade only ever needs the type-hint-bearing
BatchRecord family, the 4 read-path ORM-row serializers actually
used inside the package, the 3 documented private helpers, and
the 7 function-level re-exports the spec promises. Everything
else was carryover from the original store.py header.
Tests at exact baseline: 1 failed, 1176 passed, 10 skipped
(the 1 failure is the pre-existing test_provider_detail isolation
flake documented in the spec).
Behaviour-preserving structural split of the 2,995-LOC store.py into
a 14-module subpackage with a thin facade. CycloneStore class keeps
its full method surface as 1-line delegations to module functions.
14 modules:
exceptions, records, orm_builders, ui, write,
batches, claim_detail, kpis, acks,
backups, inbox, providers
(+ __init__.py facade)
Facade re-exports 12 public symbols (CycloneStore, store, BatchRecord*,
BatchKind, AlreadyMatchedError/NotMatchedError/InvalidStateError, utcnow,
dashboard_kpis, check_matched_pair_drift) + 3 private helpers
(_claim_status_from_validation, _persist_835_remit, _remittance_835_row)
to preserve the 4 test files that import them.
Zero public API changes, zero test changes, zero importer changes.
CycloneStore._lock and CycloneStore._batches.clear() remain intact for
the 7 test files still using the cleanup idiom.
Verified: 1,176 / 1 (pre-existing isolation flake) / 10 tests pass —
identical to baseline.
Fresh plan that supersedes the 2026-06-21 line-number-anchored plan.
Reflects the resumed state: store.py at 2,995 LOC, 14 target modules,
1,176/1/10 test baseline, 3 new symbols to extract (dashboard_kpis +
_claim_state_str → kpis.py; check_matched_pair_drift → claim_detail.py),
3 private-helper re-exports (added _persist_835_remit + _remittance_835_row
discovered during the audit).
Per-task code copies dropped in favor of function-name references +
read-store.py guidance — the line numbers in the original plan are
inherently stale against a 2,995-LOC file under active development.
The original 2026-06-21 plan is preserved on disk as historical record
of the design conversation.
Update the 2026-06-21 approved spec with the post-SP27 reality:
store.py grew 2,412 → 2,995 LOC. Three new top-level symbols
(dashboard_kpis, _claim_state_str, check_matched_pair_drift) get
slotted into the new kpis.py and claim_detail.py. Three private
helpers (the original _claim_status_from_validation + the newly-
discovered _persist_835_remit and _remittance_835_row) are re-
exported from the facade to preserve the 4 test files that
import them. Branch bumped to sp21-store-split per SP-N convention.
All previously-locked Decisions are preserved verbatim.
Atomic SP-N merge per cyclone-spec. Carries the remittances
architecture refactor (handlers/ extraction, unified 835 ingest +
reconcile, server-aggregated KPIs) plus two same-increment fixes
for bugs surfaced against the running stack:
- fix(sp27): /api/claims + /api/remittances total counts the
full population (previously page-local reduce)
- feat(sp27): server-aggregate Dashboard KPIs so the 100-row
sample doesn't lie
- fix(sp27): Claim.patient_control_number populated from CLM01
(claim_id), not 2010BA NM109 (member_id) — restores 837↔835
auto-match via the existing reconcile.by_pcn join
- feat(sp27): server-aggregate Remittances KPIs (count, paid,
adjustments)
Includes migration 0017 (UPDATE claims SET patient_control_number
= id) which was applied to the live DB at ingest time.
The Remittances page's three KPI tiles — REMITS / TOTAL PAID /
ADJUSTMENTS — were computed page-locally via items.reduce(...) over
the merged tail of the current page + live delta. With a 100-row
default limit, a 1,739-row population showed count=100, paid=$16,934,
adjustments=$147 — silently understating reality because the page
hadn't loaded the remaining rows yet.
This change mirrors the silent-incompleteness fix that
/api/dashboard/kpis (commit 59c3275) and /api/remittances (commit
d81b6ed) made for their tiles:
* CycloneStore.summarize_remittances() iterates the full filtered
remittance population (no limit) and returns
{count, total_paid, total_adjustments}. Mirrors iter_remittances
with limit=_ITER_UNBOUNDED.
* GET /api/remittances/summary — server endpoint with the same
filter parameters as /api/remittances. Registered BEFORE the
/api/remittances/stream handler so FastAPI doesn't treat
'summary' as a stream sub-path.
* api.listRemittanceSummary + useRemittanceSummary hook.
* Remittances.tsx swaps off items.reduce, consumes the server
summary. Tiles render the server totals so the values reflect
the entire DB population, not the page-local sample.
Verified live: /api/remittances/summary returns
{count: 1739, total_paid: 227181.58, total_adjustments: 13792.65},
which matches DB ground truth exactly.
Tests: 8 new backend tests in test_api_remittances_summary.py; 1 new
frontend test in Remittances.test.tsx (kpi_tiles_use_server_summary_not
_page_local_reduce) plus the page-level test for the zero-valued mock
default.
The 837 ingest path (_claim_837_row in store.py:194) populated
Claim.patient_control_number from claim.subscriber.member_id — the
subscriber's 2010BA NM109 Medicaid ID — instead of from
claim.claim_id (CLM01, the claim submitter's identifier the 837
actually sent).
That silently broke every downstream join that uses this column as a
cross-reference key:
* reconcile.match() (reconcile.py:74) — joins
Claim.patient_control_number against
Remittance.payer_claim_control_number (which is parsed from CLP01,
the 835's echo of CLM01 per X12 spec). Member_id never matches
CLP01, so auto-match always fails.
* apply_999_rejections — same lookup, same broken key.
* apply_277ca_rejections — same lookup, same broken key.
* scoring.score_pair — same broken key.
Live DB probe (1,739 remits, 337 claims):
* Claim.id == Remit.payer_claim_control_number → 0 matches
* Claim.patient_control_number == Remit.payer_claim_control_number
→ 9 matches (substring coincidences; synthetic PCN strings share
alphanumeric characters with the human-readable member_ids)
* Claim.matched_remittance_id NOT NULL → 0 claims
This commit changes _claim_837_row to write
Claim.patient_control_number = claim.claim_id (= CLM01). The
reconcile matcher's existing join now hits the row the 835 echoes
back. Companion migration 0017 backfills the 337 pre-fix rows so
they're on equal footing with new ingests (UPDATE claims SET
patient_control_number = id WHERE patient_control_number IS DISTINCT
FROM id — idempotent).
Tests:
* 2 new RED→GREEN tests in test_store_reconcile.py:
- test_837_ingest_populates_patient_control_number_from_claim_id
pins the field semantics directly
- test_837_then_835_with_echoed_pcn_auto_pairs proves the full
end-to-end auto-match now fires
* 3 existing manual_match tests that relied on the bug (had setup
using member_id != claim_id to deliberately prevent auto-match)
updated to use distinct PCNs explicitly so the tests still
exercise the manual-match path with a real orphan pair.
* 3 store_claim_detail / api_gets tests adjusted for the same
reason.
Verified: 1,176 / 1,177 backend tests pass; the one failure is the
pre-existing flake in test_provider_extended_response.py noted before
this work started.
Caveat for the existing dev DB: the 1,739 remits already in the DB
were ingested from 835 fixtures whose CLP01 is a different synthetic
identifier than the 837's CLM01 (the test fixtures never echoed
CLM01 — a fixture-data limitation, not a code bug). After this fix,
new 837+835 ingest pairs whose payer echoes CLM01 in CLP01 will
auto-match as expected. The pre-existing 1,739 remits will continue
to land in the unmatched bucket; that can only be fixed by
regenerating the test fixtures (out of scope for this SP).
Before this fix, the list endpoints computed `total` via
`len(list(store.iter_*(**common)))`. Both `iter_claims` and
`iter_remittances` default to `limit=100`, so the reported total
silently capped at 100 even when the DB held 60k claims or 835
remits. The frontend rendered a `data.total` of 100 in the KPI
tile and a 100-row table, the page looked complete, and the bug
stayed hidden — exactly the Dashboard silent-failure pattern that
59c3275 (server-aggregated KPIs) was meant to retire.
The Remittances page symptom reported on Jun 29 ('REMITS 100',
empty CLAIM column on 100 rows) was this bug. The empty CLAIM is
a separate matching concern (those remits have `claim_id = NULL`
in the DB); the count fix addresses the population-size lie.
Fix:
* `CycloneStore.count_claims` + `count_remittances` reuse the
iter's filter pipeline (DB filters + in-memory payer/date
filters) with an effectively-unbounded limit so the count
reflects the true DB population.
* `list_claims` + `list_remittances` call the new count
helpers instead of slicing `iter_*` twice.
* 13 new tests in `test_list_endpoint_counts.py` cover the
empty/filter/per-dimension/cardinality cases plus the HTTP
regression (seed 150/120, assert total matches).
Bonus fix:
* `conftest._reset_rate_limit_buckets` walks the middleware
stack and clears `RateLimitMiddleware._buckets` between
tests. Without this, the full suite tripped the 300 req/60s
rate limiter mid-run and 9 later tests (4 of mine, 5
pre-existing in test_inbox_endpoints / test_payer_summary)
got 429s. All 1167 tests now pass.
Follow-ups noted but out of scope:
* `/api/admin/audit-log`, `/api/admin/backup/list`,
`/api/admin/scheduler/processed-files` use the same
`len(rows)`-after-`.limit(limit)` pattern. Admin-only,
no `has_more` consumption, so impact is bounded.
* `count_*` could short-circuit to `func.count()` to skip
the UI-dict build, but iter already calls `q.all()` so
the win is modest.
The Dashboard was hardcoded to useClaims({ limit: 100 }) and reduce
KPIs client-side. With 60k+ claims in production, every tile
(Billed $940K, Received $59K, Denial rate, Pending AR, monthly
sparkline, top providers, recent denials) was computed from a
0.16% sample of the dataset — silently wrong numbers on the
operator's primary view.
Fix: add GET /api/dashboard/kpis that aggregates server-side in
one read over the entire claim population. The new useDashboardKpis
hook consumes it and polls every 60s. Dashboard.tsx drops
useClaims({limit:100}) + useProviders() + the client-side
buildMonthly reduce.
Backend:
- store.py: dashboard_kpis() — one Claim query (selectinload on
batch to avoid N+1) + one bulk Remittance lookup, Python reduce
over the full population. Zero-filled response for empty DB.
- api.py: GET /api/dashboard/kpis behind matrix_gate, query-param
clamps (1..24 months, 0..50 top_n_*).
Frontend:
- api.ts: DashboardKpis types + getDashboardKpis() wrapper.
- useDashboardKpis.ts: TanStack Query hook, 60s refetchInterval,
bypass to data:undefined when not configured.
- Dashboard.tsx: switched to useDashboardKpis, extracted
ZERO_TOTALS constant, dropped the buildMonthly helper.
Tests:
- backend/tests/test_dashboard_kpis.py: 12 tests covering empty DB,
matched-remit math, pending-state semantics, monthly binning,
top-providers/top-denials sort + cap, orphan-claim defensive
guard, HTTP wiring + param validation.
- src/hooks/useDashboardKpis.test.ts: 3 tests for the hook
contract (configured path, unconfigured fallback, param
passthrough).
- src/pages/Dashboard.test.tsx: wrapped renders in
QueryClientProvider + stubbed useAuth + isConfigured=false. This
fixes 3 pre-existing Dashboard test failures (the page never had
a QueryClient set up because useClaims/useProviders were the
first useQuery hooks in the page).
Reviewer fixes (same commit):
1. topDenials sort placed empty submissionDate claims first under
reverse-lex. Drop them at append time.
2. r.batch lazy-load → N+1 on 60k rows. selectinload(Claim.batch).
3. pending_states rebuilt per call as a mutable set — moved to
module-level _DASHBOARD_PENDING_STATES frozenset.
4. Module-level ProviderORM import inconsistent with the
"local import inside the function" pattern — moved inline.
Add check_matched_pair_drift() at module level in store.py — read-only
audit of the Claim.matched_remittance_id ↔ Remittance.claim_id FK pair.
Logs WARNING on drift with up to 5 examples of each of two cases
(claim-side and remit-side), returns the count of drifted rows. Wired
into api.py::lifespan right after db.init_db() and ensure_clearhouse_seeded(),
wrapped in try/except so a query failure logs but doesn't crash boot.
The symmetric-write + symmetric-clear invariants on
manual_match / manual_unmatch were already correct; this commit pins
them with focused regression tests in test_store_match_invariant.py
(8 tests covering both directions, both happy-path, rollback pin, and
drift-check unit behavior). PCN asymmetry in the fixture prevents the
auto-match inside CycloneStore.add (Task 10) from pre-pairing, so
manual_match is the only writer.
Migration 0016 adds the missing ix_claims_matched_remittance_id index —
the drift check scans WHERE matched_remittance_id IS NOT NULL on every
boot and would become a full-table scan past ~10k claims. Symmetric
with ix_remittances_claim_id (added in 0007). Migration tests bumped
from head=15 to head=16.
Move 'reconcile.run(s, record.id)' inside CycloneStore.add()'s ingest
session, before s.commit(). The placeholder adjustment_amount set by
_remittance_835_row is overwritten by reconcile's CAS-aggregate pass
in the same transaction — readers never see a half-reconciled
Remittance row. If reconcile raises, the entire 835 ingest rolls back
via the session's __exit__.
The previous flow committed batch + remittance rows in session-1,
then opened session-2 to run reconcile.fail-soft. Two visible
problems closed: a race window where readers fetched the placeholder
adjustment_amount, and a half-reconciled state left visible if
reconcile crashed.
Deviation from the plan (N4 in autoreview): the reconcile call lives
in cycl_store.add() rather than handle_835 calling a new
reconcile.run_now(batch_id) helper after add(). Same end state, one
fewer module surface, handler stays a thin wrapper over the store.
The 06/25 silent hang was a hung ``sftp.listdir_attr()`` on the
worker thread — paramiko TCP-acked then went silent, the scheduler's
``asyncio.to_thread`` waited forever, and the operator had no
signal that polling had stalled. Every poll cycle since was
suspected of the same failure mode.
``backend/src/cyclone/clearhouse/__init__.``
- New ``_op_timeout_seconds()`` helper reads
``CYCLONE_SFTP_OP_TIMEOUT_SECONDS`` (default 30s). Rejects
unparseable, zero, and negative values — ``asyncio.wait_for(timeout=0)``
raises immediately and ``timeout<0`` is undefined per the asyncio
docs, so a typo would silently turn every SFTP call into an
instant failure. Logs a WARNING and falls back to the default.
- New ``async_list_inbound()`` async wrapper applies
``asyncio.wait_for(asyncio.to_thread(self.list_inbound),
timeout=N)``. ``wait_for`` cancels the awaiter after N
seconds but the worker thread keeps running until paramiko returns
on its own (paramiko is not asyncio-aware, can't be cancelled
cleanly). ``asyncio.TimeoutError`` propagates so the scheduler
can surface it as a transient SFTP error.
``backend/src/cyclone/scheduler.py``
- ``_tick_impl`` now calls ``client.async_list_inbound()``
instead of ``asyncio.to_thread(self._list_inbound)``. Catches
``asyncio.TimeoutError`` explicitly with a clear error message
("list_inbound: timeout") — separate from the generic
``Exception`` catch-all so the operator's tick-result error
reads as the actual cause.
- Deleted the now-dead ``Scheduler._list_inbound()`` shim.
``backend/tests/test_sftp_op_timeout.py`` (new, 6 tests):
1. Default timeout is 30s when the env var is unset.
2. Operator can override via env var without restart-rebuild.
3. Unparseable value (e.g. "30s") falls back to default.
4. Zero and negative values fall back to default.
5. A hanging list_inbound raises ``asyncio.TimeoutError`` within
the configured bound (the 06/25 hang pin).
6. A non-hanging call returns the stub's empty list normally
(sanity check that the wrapper doesn't break the happy path).
Scope note: only ``async_list_inbound`` is wired up. The other
SFTP methods (``list_inbound_names``, ``download_inbound``,
``read_file``, ``write_file``) are called from
operator-triggered paths (admin endpoints, CLI, claim submission)
where the operator can Ctrl-C the request, so a hang is at least
visible. Wrapping them would require making the FastAPI handlers
async, which is out of scope for Task 8. Tracked as a follow-up —
worth folding into the same shape when those endpoints are next
touched.
Gainwell's production filer has shipped at least two inbound filename
shapes — the spec form with a trailing `_{file_type}.x12` suffix and
a shorter suffix-less form where the disambiguator token (between
`-` and `_M`) doubles as both orig_tx and file_type. The 6/15–6/19
835 batch arrived in the suffix-less form, and the strict
`INBOUND_RE` rejected them outright — the scheduler silently
dropped 5 days of production data without logging an error.
`backend/src/cyclone/edi/filenames.py`
- New `INBOUND_RE_LOOSE` regex: same prefix/tpid/tracking/ts/seq
rules as `INBOUND_RE`, but the disambiguator token is required
to be 3–5 uppercase alnum (covers 999, TA1, 835, 277CA, ENCR; the
5-char cap stops the engine from over-eating the next `_M` token
in a degenerate input).
- `parse_inbound_filename` now tries `INBOUND_RE` first
(preserves historical behavior for every existing caller) and
falls back to `INBOUND_RE_LOOSE`. In the loose form, orig_tx is
set to the disambiguator token so the parsed shape matches what
the strict form produces when orig_tx == file_type. The
`ALLOWED_FILE_TYPES` check is enforced in both branches.
- `is_inbound_filename` is loosened in the same shape so the two
never disagree — a refactor that pre-filters a directory listing
with `is_inbound_filename` then re-parses with
`parse_inbound_filename` would otherwise see the suffix-less
files rejected twice.
`backend/tests/test_inbound_filename_loose.py` (new, 10 tests):
1. Spec form with explicit `_835.x12` suffix still wins (strict
path unchanged).
2-5. Suffix-less 835 / 999 / 277CA / ENCR all parse correctly.
6. Suffix-less `.txt` is still rejected (the `.x12` ext check
applies to both forms).
7. Suffix-less unknown type (4-char `ABCD`) is rejected by
ALLOWED_FILE_TYPES — the loose regex's `{3,5}` shape would
otherwise let it through.
8. Suffix-less 6-char token (`999XX6`) is rejected by the
5-char cap, preventing the engine from swallowing the next
`_M` token.
9. Strict form takes precedence over the loose form when both
match — pinning the parser's branch order so a refactor can't
silently change the parsed shape.
10. `is_inbound_filename` accepts the loose form, the spec form,
and rejects garbage.
Live smoke: 5/5 suffix-less Gainwell patterns now parse correctly
(were ValueError before); spec form unchanged; 4 invalid forms
still rejected. Full backend suite: 1085/1121 — the 36 pre-existing
failures (test_serialize_837, test_api_stream_live,
test_inbox_endpoints) are unrelated and confirmed pre-existing by
running them on stashed pre-change code.
The Acks page silently capped at 100 of 1056 rows in the operator's
DB: the eyebrow read `${items.length} on file` (not the server's
`total`), the KPI strip summed from the 100 visible items, and the
endpoint accepted no `offset` — so the user had no signal that 956
more acks existed. Same class of bug on the Activity page (cap=200,
no 'X of Y' hint).
Backend
- /api/acks (acks.py): add `offset`, bump `le=1000`→`le=5000`,
slice `rows[offset:offset+limit]`, return server-side
`aggregates` (accepted/rejected/received summed over the full
row set, not the page) so the KPI strip reflects every persisted
999 instead of just the visible 50.
- /api/activity list + stream (api.py): bump `le=500`→`le=5000` so
the page can ask for a denser snapshot.
- /api/277ca-acks (api.py): bump `le=1000`→`le=5000` for
consistency.
- /api/ta1-acks: left at `le=1000` — TA1s aren't shipped today and
the structural fix (offset + aggregates) wasn't applied, so a
larger cap would just make the same latent silent-failure easier
to hit. (TODO: fold in the same shape when Gainwell starts
shipping TA1s.)
Frontend
- listAcks (api.ts): accept `offset`, surface `aggregates`,
adapt wire `*_count` keys to the in-page
`accepted`/`rejected`/`received` shape so the page can use
`data.aggregates` as a drop-in for the page-local fallback
accumulator.
- useAcks (hooks): pass `offset` through; return type carries
`aggregates`.
- Acks.tsx: add `page` state (PAGE_SIZE=50), use `data.total`
for eyebrow + watermark (not `items.length`), use
`data.aggregates` for the KPI strip (with in-page fallback
accumulator on first paint), render `<Pagination>` when
`totalCount > PAGE_SIZE`. Footer row reads "N rows on file"
instead of "N rows".
- ActivityLog.tsx: bump `limit: 200`→`limit: 500`, eyebrow reads
"Activity · showing N most recent" to make the bounded-window
semantics honest (the endpoint doesn't expose a true total — it
reports events matching the current kind/since filter, capped at
the request limit).
Tests
- test_acks.py: 4 new tests pin the fix:
1. `offset` walks the full set; `has_more` flips at the
boundary.
2. `aggregates` reflects the full row set, not the page (the
silent-failure pin) — and stays stable across page slices.
3. `limit` cap of 5000 is enforced (422 above it).
4. `offset` past the end returns an empty page with stable
aggregates (a stale UI page state across a row count change
must not 500 or zero the KPIs).
Live smoke-verified: /api/acks?limit=2&offset=0 vs ?offset=2 return
the expected row slices, aggregates stable at 15/10/15 for 5 seeded
rows, /api/acks?limit=10000 rejected with 422.
Triage note: the TA1 section (`Ta1AcksSection`, lines 609-616 of
Acks.tsx) has the same latent silent-failure pattern (page-sums
KPIs, no offset on /api/ta1-acks). Left untouched because the
empty-state copy says Gainwell doesn't ship TA1s today and the
larger structural fix belongs in a follow-up.
CycloneStore split precedent (SP21) — lift three helpers from
scheduler.py + api.py into one module. Both callers will switch
to this in Task 6. The new package also defines HandleResult
and the HANDLERS registry; handle_999 / handle_ta1 / handle_277ca
/ handle_835 fill in over Tasks 2-5.
The registry is lazy + best-effort: register_handlers() catches
broad Exception so a partial-modification SyntaxError in one
in-flight handler module can't break scheduler or API import.
11 tests added; existing suite unchanged (1 failed + 2 errors
pre-existing in test_provider_extended_response.py are not
introduced by this commit).
Mirrors the existing admin_username / admin_pw pattern so the dev
compose loads SFTP creds from /tmp/cyclone-test-secrets/sftp_password
when present. Falls back to the CYCLONE_SFTP_PASSWORD env var if the
file is missing. Pre-existing env-var support from SP25+26 unchanged.
