A parking lot is one pool of spaces with a flexible set of entry/exit
points — no "lane". Direction is a property of each RELAY inside an access
controller; readers/cameras bind to a controller relay and inherit it.
Schema:
- drop `lane` from ledger_events, device_events, sessions
- rename lane_devices -> devices (no lane/direction columns)
- access config.relays=[{relay,direction,button?}]; reader/camera
config.controllerId+relay binding
- fresh 0000_baseline migration (history reset; dev data was throwaway)
Signed ledger:
- remove `lane` from canonicalize(); bump signer keyId sw-hmac-v1 -> v2
(v1 events won't verify under v2 — intentional, gated per-event by keyId)
Server:
- new device-resolve.ts (replaces lane-map.ts): relayForButton,
relayForDevice, firstRelayByDirection, devicesByDirection
- entry-flow: button terminal -> its relay; exit/permit: reader's bound
relay; dispatcher resolves the bound relay + inherited direction
- camera snapshots fire by direction site-wide, async, never block open
- DeviceConfig widened to nested JSON for relays[]
Web:
- wizard: no lane selector; add controllers (relay map + entry-button
terminal) first, then bind readers/cameras/printers to a controller relay
Wiki: new entry-exit-points.md (replaces lane-direction); reworked
entry-exit-readers, parking-session, first-run-setup, device-registry,
append-only-event-chain, device-events; removed stale lane/LaneMap mentions.
The reader sends Connection: keep-alive but only acts on the verdict (beep,
output) once the TCP socket closes. Fastify's default kept the connection alive,
so the reader waited out a ~10s keep-alive timeout before beeping — even though
the server replied in ~15ms. Every vendor demo replies Connection: close and
shuts the socket. Set reply.header('connection','close') on the QR endpoint.
Verified the header is now sent; symptom was correct accept/reject with a ~10s
lag before the beep.
The QR reader is a push device and the setup wizard assigns random-UUID ids, so
'id = serial' can't be set via the UI. Add a dedicated gee-qr-reader driver
(reader category) with a single 'serial' config field; the admin assigns it
normally and enters the device's serial (its cjihao).
The QR endpoint now resolves the lane by matching lane_devices.config.serial to
the scan's cjihao (instead of row id == cjihao), so no DB hand-editing. An
unassigned serial resolves to no lane -> status:0, gracefully.
Verified via inject through the real /api/setup/assign: assign {serial:
H05M2AFA} -> .jsp scan with a matching permit QR -> status:1 (accept) + open;
re-scan -> permit exit; unknown card -> status:0; unassigned serial -> status:0.
Hardware capture: the GEE/Fondvision reader (serial H05M2AFA) scans + sends +
beeps fine — the earlier 'no beep' was just nothing answering :3000. Real
request: GET /qa/mcardsea.jsp?cardid=...&cjihao=H05M2AFA&... — the 'server
language' setting (JSP here) selects the URL EXTENSION, so it posts .jsp, not
.php. Our route was .php-only and would have 404'd it.
Register the endpoint at php/jsp/asp/aspx/cgi so it works whatever the device is
configured to. cjihao (serial) is the lane key: assign the reader as
lane_devices.id = its serial.
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.
