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.
Brings the SP5 live-tail implementation into main:
Backend
* EventBus (cyclone.pubsub): per-kind fan-out with drop-oldest overflow
* FastAPI lifespan initializes the bus + db once per process
* store.add() publishes claim_written / remittance_written /
activity_recorded events on every batch write
* GET /api/{claims,remittances,activity}/stream: NDJSON snapshot +
live subscription + 15s idle heartbeat
* EventBus.unsubscribe() lets the tail loop release its queue on
client disconnect (no queue leak per open stream)
Frontend
* src/lib/tail-stream.ts: streamTail() async-generator over fetch
* src/store/tail-store.ts: zustand with FIFO cap 10k per slice
* src/hooks/useTailStream.ts: connecting/live/reconnecting/stalled/error/closed
state machine with 1→2→4→8→16→30s backoff
* src/hooks/useMergedTail.ts: base + tail merge with filter
* src/components/TailStatusPill.tsx: badge + Reconnect button
* Claims, Remittances, ActivityLog pages wired to the tail
Tests
* 437 backend tests pass (was 418 before SP5)
* 154 frontend tests pass (was 124)
* npm run typecheck clean
* end-to-end smoke: open /api/claims/stream, POST 837, see new claims
arrive in real time without refresh
