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.
Add the rongta PrinterDevice driver (ESC/POS over raw TCP 9100) and the
device-agnostic pieces around it:
- Roles + failover: each printer declares a role (entry-dispenser/booth-
receipt) and failoverRank; printer-routing.ts picks the best healthy printer
and falls back outside->booth for entry tickets (never the reverse).
- Live status: MonitorableDevice.readStatus()/PrinterStatus capability. The
Rongta driver scrapes the device's own /prn_stat.htm (Cover/Cutter/Paper
End/Near End/Off-Line) rather than hand-decoding DLE EOT, whose reply bytes
on this clone don't match the canonical ESC/POS bit layout (verified on
hardware) -- avoids a false-healthy. Maps to ready/degraded/offline, fail
safe on an unreachable or unexpected page.
- Server PrinterMonitor polls enabled printers (PRINTER_POLL_MS, default 5s),
caches latest, emits "printer-status" on change. Exposed via
GET /api/printers/status and an SSE stream for the booth UI.
Verified against 10.0.10.6: ready when healthy, offline when unreachable
(no throw), bus emits on change and suppresses unchanged reads.
Wiki: new rongta-printer entity, printer-roles-failover and
printer-status-monitoring concepts; BOM/index/log updated.
