Migration 0014 changes the PRIMARY KEYs of claims and remittances from
single-column id to composite (batch_id, id). Enables the spec'd
cross-batch CLM01 / CLP01 collision workflow: same CLM01 in multiple
batches is now representable (resubmits), pre-flight dedup 409 path is
genuinely exercisable, force-insert can skip pre-existing duplicates.
Strategy: PRAGMA defer_foreign_keys = ON + table recreation for every
table whose FKs pointed at the old single-column PK. Tables recreated:
remittances, claims, matches, cas_adjustments, service_line_payments,
line_reconciliations. Each child table gains a batch_id (or
remittance_batch_id) column for the composite FK side; INSERT INTO new
SELECT FROM old JOINs populate it from the already-recreated parent.
Cross-table FKs (remittances.claim_id, claims.matched_remittance_id)
cannot be SQL-enforced with composite PKs (SQLite has no ALTER
CONSTRAINT). Dropped at SQL level; enforced via application-layer
invariants in store.manual_match / manual_unmatch / reconcile.run and
the dedup.preflight_* helpers.
ORM updates (db.py):
- Claim / Remittance: composite PK via explicit PrimaryKeyConstraint in
__table_args__ (column order matches SQL: batch_id, id).
- New Claim.matched_remittance_batch_id column.
- Match / CasAdjustment / ServiceLinePayment / LineReconciliation:
added the batch side of their composite FK to the parent table.
- SQLAlchemy before_insert events auto-populate the batch side of the
composite FK from session.new, then identity_map, then SQL fallback.
Production code updates:
- store.manual_match / manual_unmatch: also write
matched_remittance_batch_id on the claim (was missing).
- api.py manual-match endpoint: same fix.
- reconcile.run: same fix for auto-matched pairs.
Test updates: replaced s.get(Claim, X) with the composite key
(batch_id, id) where batch_id is known, or s.query().filter().first()
where the test only knows the id. Tests that previously inserted a Match
row pointing at a non-existent Remittance now seed the parent Remittance
so the new NOT NULL composite FK is satisfied.
Closes the gap between the SP10 backend (5 lanes) and the SP6
frontend (4 lanes). The Payer-Rejected lane (277CA STC A4/A6/A7)
is now rendered alongside Rejected/Candidates/Unmatched/Done,
with an Acknowledge bulk action that drops claims from the
working surface without erasing the original 277CA rejection
event (audit log stays intact, SP11).
Backend:
* Migration 0010: add payer_rejected_acknowledged_at +
payer_rejected_acknowledged_actor columns + partial index.
* db.py: surface the two new columns on the Claim model.
* inbox_lanes.py: filter acknowledged claims out of the
payer_rejected lane; expose the new fields on the row payload
for forward-compat (e.g. a future 'Recently acknowledged' view).
* api.py:
- POST /api/inbox/payer-rejected/acknowledge
Bulk-acknowledge. Idempotent. Returns transitioned /
already_acked / not_found / not_rejected counts so the UI
can show '3 of 5 were already acknowledged' on a noop bulk.
Writes a 'claim.payer_rejected_acknowledged' event to the
SP11 hash-chained audit log.
- GET /api/inbox/export.csv: accept 'payer_rejected' lane.
* test_acks.py: bump user_version assertion to 10.
* test_lane_filter_acknowledged.py: 4 tests for the lane filter
and forward-compat row payload.
* test_payer_rejected_acknowledge.py: 6 tests for the endpoint
(happy path, idempotency, no-op on non-rejected, missing
ids, 400 on empty, audit-log wiring + chain integrity).
Frontend:
* lib/inbox-api.ts: add payer_rejected to InboxLanes, add
acknowledgePayerRejected(), update exportInboxCsvUrl union.
* hooks/useInboxLanes.ts: add payer_rejected to initial state.
* hooks/useInboxLanes.test.ts: add payer_rejected to mocks.
* components/inbox/BulkBar.tsx: add 'payer_rejected' lane with
Acknowledge action (no Resubmit, no Dismiss — payer-rejected
is not eligible for either).
* components/inbox/BulkBar.test.tsx: add payer_rejected test.
* pages/Inbox.tsx: render the 5th lane, hook up onAcknowledge,
include payer_rejected in the needEyes count.
* pages/Inbox.test.tsx: 3 new tests (5-lane render, need-eyes
count, acknowledge action hits the right endpoint).
* components/inbox/InboxHeader.tsx: doc comment now explains
why payer_rejected rolls up into need-eyes.
Pre-existing typecheck warnings in BulkBar.test.tsx / InboxRow
.test.tsx / Lane.tsx / download.test.ts are unchanged from
main — not touched here.
Test counts: backend 724 -> 734 (+10). Frontend 350 -> 354 (+4).
