Booking/inspection/maintenance/outbox dates were authored as absolute
timestamps around a fixed 2026-08-01 anchor and never re-anchored at
seed/reset time, so demo scenarios (e.g. BK-DEMO-RETURN) silently drifted
into the past. Every reset now shifts seeded dates by (today - authored
anchor); dashboard's "today" filter uses real wall-clock time instead of
the now-removed frozen demo_today setting. Adds seed-validation tests
proving scenarios S1/S2/S4/S5 are present and internally consistent after
every reset.
Ran a dedicated post-M7 release-readiness audit. Found and fixed the one real gap: mypy
was a declared dev dependency but had never been run in any milestone's validation loop.
Fixed all 43 pre-existing type errors it surfaced, including two genuine defensive-
programming gaps (unguarded Optional vehicle/customer lookups that could have crashed
with unhandled 500s instead of clean 404/401 responses) rather than suppressing them.
make lint now runs ruff + mypy; mypy reports zero errors across 44 source files.
Re-verified end to end against a genuinely wiped-volumes clean checkout: automatic
migrations, deterministic seed, 66/66 backend tests, and the full user-journey matrix
(login, dashboard, vehicle/booking detail, return workflow, invalid-mileage rejection,
data-quality review, duplicate-customer merge, audit trail, Knowledge Assistant, n8n,
MCP Hub) via curl and Playwright.
Live-verified both external-dependency degraded modes, not just unit tests: stopped n8n
mid-flow and confirmed a return still commits with the outbox event staying pending and
retrying with backoff, then self-healing to succeeded with zero manual intervention once
n8n came back; verified RAGcore's unavailable-degradation path against an unreachable
host. Added frontend/e2e/interactive-elements.spec.ts (11 tests covering every nav item,
filter, tab, and role boundary) alongside the existing demo script test — 12/12 e2e tests
passing.
Verified no secrets are committed (.env never tracked, clean git history scan) and
.env.example covers every operator-configurable setting. Confirmed no placeholders,
TODOs, fake responses, hardcoded metrics, or dead routes anywhere in the codebase.
Updated README.md with an honest integration-status section and PROJECT_STATE.md with
the full audit findings. Added artifacts/final-acceptance/summary.md as the authoritative
final evidence document (commands, results, URLs, demo access, integration status per
external dependency, known limitations, deployment instructions, five-minute demo flow).
Outbox dispatcher (background thread, FOR UPDATE SKIP LOCKED claim, exponential backoff, no transaction held during HTTP I/O). n8n callback endpoint with shared-secret auth and idempotency by event ID. Automation nav + UI with manual retry. 49 backend tests passing, ruff clean. Fixed a crash-on-redelivery bug in seeded outbox payloads and made the dispatcher defensive against malformed payloads. Verified the full live round trip against a real n8n instance: return -> outbox -> dispatcher -> n8n workflow -> callback -> succeeded, including the S5 failed-retry demo scenario.
Five rule scanners (duplicate customers, missing fields, odometer regression, booking overlap, status conflict) run automatically after seed and via an explicit scan endpoint. Issue defer/reject/merge-customers endpoints with transactional customer merge (booking rewiring, tombstone, audit). Data Quality nav + workbench UI with two-column duplicate comparison and inline (non-native) confirm. Dashboard attention items now link to issues. 35 backend tests passing, ruff clean. Fixed a real false-positive bug in odometer-regression detection found through iteration on seed data, and two TS narrowing errors. Verified end-to-end via browser: S2 merge and S4 overlap scenarios.
Transactional return command with idempotency, row-lock concurrency control, odometer-regression handling, vehicle status derivation, outbox event, audit trail. Result-summary UI on booking detail. 26 backend tests passing, ruff clean. Verified end-to-end via browser against S1 demo scenario; fixed two real defects found only through browser testing (UI state loss on status transition, unflushed UUID default).
