server: GEE/Dingtian QR reader endpoint + synchronous ReadOutcome

Browse Source 
The reader HTTP-GETs on each scan and beeps/acts on our JSON reply (host-in-the-
loop, synchronous). New route GET/POST /qa/mcardsea.php parses the SDK query,
runs the scan through the read dispatcher (permit match -> permit flow; else
transient exit), and replies the SDK verdict: status 1=valid (beep 2x) /
0=invalid (beep 1x), output, time-sync.

Refactored the read flows to return a ReadOutcome {accepted, direction, reason}
so the reply reflects the real accept/reject decision (ReadDispatcher.dispatch,
ExitFlow.handleAt, PermitFlow.run). Fire-and-forget readers ignore it.

Reader's lane is keyed off its serial (cjihao) as lane_devices.id for now;
endpoint is public (reader has no auth, on the device subnet).

Verified via inject: valid permit QR -> status:1 + open; re-scan -> permit exit;
unknown QR -> status:0; barrier-less lane -> status:0.

- NEXT: backend route — parse GET, DECIDE (reuse permit/exit lookup), reply JSON verdict, emit on
read bus. Refactor read flows to RETURN an outcome so the reply can reflect accept/reject.
## [2026-06-16] build+fix | QR reader endpoint + ReadOutcome refactor; dev-DB migrate fix
- DB FIX: dev server crashed `no such table: lane_devices`. Cause: server `.env` DATABASE_URL points
at `apps/server/parking.sqlite` (the old dev DB I'd moved aside during the ledger split; new
migrations added since). Applied `drizzle-kit migrate` to that path → all 14 tables present. Fresh
DB → needs `seed-admin` + device re-assignment (empty, expected).
- REFACTOR: read flows now RETURN a `ReadOutcome {accepted,direction,reason}` (device-events.ts).
`ReadDispatcher.dispatch`, `ExitFlow.handleAt`, `PermitFlow.run` updated. A synchronous reader can
answer the device; fire-and-forget readers ignore it.
- ENDPOINT: `routes/qr-reader.ts` — `GET/POST /qa/mcardsea.php` (public; reader has no auth, on the
device subnet). Parses the SDK GET, dispatches the scan, replies the SDK verdict (status 1/0 →
beep 2×/1×, output 0, time-sync). Reader's lane keyed off device serial (cjihao) as lane_devices.id
for now.
- VERIFIED via inject: valid permit QR→status:1+open; re-scan→permit exit; unknown→status:0; reader
on barrier-less lane→status:0. Full build 5/5.
- Updated [[gee-qr-er80]] (endpoint as-built + hardware open items).
