The relay control password (relay_pw) was read by the driver but had NO form field,
so Test connection sent it as 0 → the device ignored the probe → a controller showed
"offline" even though it pinged. Add a "Relay control password" config field (secret;
blank keeps the stored value).
Because relayPassword is redacted from the client, the edit form can't resend it — so
the test endpoint now re-merges the stored secret by device id (mirroring save). It is
re-merged ONLY when the submitted config addresses the SAME device: matching driverId
and every connection-identity field it sets (host/port/binaryPort/httpPort/serial). A
redirected host/port or mismatched driver yields NO secret, so a probe can't exfiltrate
the password to an attacker host (the booth operator is the threat-model adversary).
testDevice() now passes the device id; setup-secrets.test.ts covers the identity guard.

Adds a bottom-of-modal "Test ANPR" button (shown only when a camera's
Plate recognition opt-in is checked) that captures a live snapshot off
the camera and runs it through the vision service, reporting the plate
read + confidence + elapsed time, or which stage failed.
- New POST /api/setup/test-anpr: builds the camera from the unsaved
config (no DB write/device change, like /test), captures a snapshot,
runs vision.analyze. Fail-soft like the runtime path (snapshot.ts):
camera/vision failures are reported results, never a 500.
- Thread the existing VisionClient into setupRoutes; add an isCamera()
type guard to @parking/devices.
- Web: testAnpr() client + AnprTestResult; button, hint, result line.
- i18n keys in sq + en (Catalog parity).

Replace the hardcoded role enum (admin/operator/cashier/readonly, checked
literally as requireRole("admin",...) across ~15 routes) with dynamic RBAC:
roles are DATA, route guards check a PERMISSION.
@parking/shared defines a code-defined grid: RESOURCES (user/role/tariff/
subscription/site/device/shift/payment/session/event/report) × Action
(create/read/update/delete + domain verbs void/cash) -> PERMISSIONS
(resource:action, e.g. tariff:update, payment:create, event:void).
DB: new roles + role_permissions tables; users.role enum -> role_id FK;
migration 0007_rbac (create tables, seed the builtin admin role + all 26
perms, seed operator/cashier/readonly composable roles matching old
behaviour, rebuild users to swap the column copying all rows).
auth.ts: JWT payload role -> roleId; permissionsFor(roleId) with an
in-memory cache + bumpPermsCache(); requirePermission(...perms) preHandler;
requireAuth for /me & /language; initAuth(db) wires the resolver once. Every
route guard mapped to a permission; device ingress (devices/qr-reader) stays
auth-free by design. New routes/users.ts (user:* CRUD, bcrypt 12, last-admin
guard) + routes/roles.ts (role:* CRUD, builtin-protected, perms validated
against the grid, cache bump on write). auth/me + /login return
{roleId, roleName, permissions, language}. seed-admin -> roleId:'admin'.
Frontend: SessionUser carries permissions + can() helper; router nav/route
guards gate by permission (requirePerm replaces adminOnly); SiteSettings
edit gated by site:update; new UsersManager + RolesManager (permission
checkbox grid; admin role locked); i18n nav.users/roles + blocks (sq+en).
Decisions: one role per user; protected built-in admin (no-lockout: the last
admin can't be deleted/downgraded); JWT carries roleId, perms resolved
per-request so role edits apply immediately (no re-login).
Verified: full build green; 20-assertion inject test passes (cashier 403s on
tariff publish + user list, admin passes, granting a perm applies on the next
request, last-admin + builtin-role protections return 409); migration 0007
applied to a copy of the live DB (incl WAL/shm) — existing admin maps to
role_id='admin', all rows preserved. Append-only event chain untouched
(event:void gates appending a void, not a delete).

- site_config gains optional park identity (park_name, operator_name, nius,
address, phone, email); additive Drizzle migration 0001. GET/PUT
/api/site-config read/write the full config (PUT partial patch, admin only);
SiteSettings + SetupWizard expose the fields.
- renderTicket() prints an Albanian header sourced from site_config, the
all-numeric 13-digit ticket id (12 random + Luhn) as Code128, large digits,
and a lost-ticket footer. CP852 codepage so ë/ç render.
- Widen the Code128 module width 2->3 and height 80->100 dots so the
short-range "Simple" QR/barcode reader decodes reliably (was barely reading
at module width 2 on the 80mm head).
See wiki/concepts/site-metadata.md and ticket-encoding.md.
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.
Replace the camera stub with HttpCamera: Hikvision ISAPI and Dahua CGI
snapshots over client-side HTTP Digest (new drivers/http-digest.ts).
healthCheck() now pulls a real frame instead of returning ready/stub.
Snapshot carries bytes (driver fetches); storage/imageRef is the caller's
job, keeping the adapter free of storage deps.
Fix the cosmetic Backend-push-IP field: add pushesToBackend to DeviceDriver
(only Dingtian sets it), expose as pushCapable in the catalog, and gate the
wizard's backend-IP fetch + field on it so pull-only devices hide it.
Verified on hardware (Hikvision 10.0.10.121): healthCheck ready,
captureSnapshot returns a valid JPEG.
Replace the hardcoded lane: 0 on input_received events with a real
device->lane lookup. A new LaneMap caches lane_devices.id -> lane,
built at startup and refreshed by the setup routes on assign/unassign.
An unmapped device logs lane: -1 + a warning (0 is a real lane) and is
still recorded faithfully (append-only chain).
source stays null for raw inputs by design: it's an IdentitySource
(how a vehicle was identified), not a device field; device provenance
remains in identity. Documented both in the wiki.
Fix two bugs found running the real assign flow: the saved web password
didn't match the device (login stayed admin/admin), and the UDP2 warning
never reached the admin.
Web password:
- Split the conflated field into webPassword (the DESIRED login; blank ->
auto-generate) and webPasswordCurrent (the device's EXISTING password used
as the old cred, default admin). Before, an admin typing a desired password
made harden send it as the old cred -> rotation failed -> but the DB still
saved the typed value, so it claimed a password the device never accepted.
- harden() now rotates current -> desired, VERIFIES by re-authenticating with
the new password, and only returns secrets.webPassword on success (else a
warning, nothing saved). Stores webPasswordCurrent for future re-runs.
- assign strips the typed webPassword/webPasswordCurrent and persists only the
verified secret -- the DB never claims an unapplied password.
Warnings to the UI:
- assignDevice returns warnings[]; SetupWizard shows them in an amber
"saved, but action needed" banner per category. This is how the admin learns
the firmware wouldn't disable UDP2 (finish in the device web UI).
Verified on hardware: after harden the device rejects admin/admin and accepts
the chosen password; the UDP2 warning surfaces.
The string protocol (UDP 60001) has no password field but can fire relays
("11" = relay 1 on), bypassing relay_pw entirely. Proven on hardware: an
unauthenticated packet opened a relay. harden() had left it enabled "for
status reads".
- #status() now reads via the authenticated binary command (relay cmd 0x00)
instead of the string protocol, so the string protocol is no longer needed.
- harden() disables the string protocol (udp2.p=255). BEST-EFFORT: firmware
V3.6J's config API silently refuses to disable udp2 (the device web UI can),
so it's not part of the blocking verify -- harden() re-checks and returns a
warning instead of throwing. After a web-UI disable, the attack is dead and
binary control/status still work (verified on hardware).
- HardenResult gains an optional `warnings[]`; the assign route surfaces them
to the admin and logs them.
- Corrected the false comment claiming relay_pw stops an attacker (it is
defence-in-depth on plaintext UDP, not a boundary).
- Thread localAddress through the driver's UDP/HTTP calls so a multi-homed
host sources device traffic from the device-facing NIC.
- Device web login (webUser/webPassword) is no longer redacted from setup
state -- it's an operational credential for the admin-only device area;
pushPassword/relayPassword stay machine-only.
Wiki: document the vuln + fix, the firmware caveat, and the out-of-band
actuation gap (the log captures host actions only; reconciliation vs. an
independent witness is the real control and is not yet built).
The data model was already multi-instance (lane_devices = one row per
instance; assign always inserts) -- the limitation was UI-only. Make the
whole flow support more than one of every category:
- Backend: add DELETE /api/setup/assign/:id (unassign by id). /state now
redacts secrets (pushPassword/webPassword/relayPassword) via a shared
redactSecrets() also used by /assign -- it was returning raw config rows.
- Web: SetupWizard reworked from one fixed slot per category into a list of
assigned instances (driver/role/host + Remove) plus an "Add another" form.
select-type config fields (e.g. printer role) now render as dropdowns.
- api.ts: add fetchState(), unassignDevice(), Assignment/SetupState types.
Verified via Fastify inject: two printers assigned to one lane both list,
no secret leak, delete -> 204, delete unknown -> 404, count drops to 1.
Full repo typechecks.
Wiki: first-run-setup documents multi-instance + delete + redaction.
harden() now rotates the device's default admin/admin web-UI login via
GET /userset.cgi?<old>&<old>&<new>&<new>& (best-effort: a failure logs
and doesn't fail the assign). The new password is stored back in config
(webUser/webPassword) so a re-run can rotate again, and is stripped from
the assign response like the push secret.
Documented the load-bearing caveat: this device's CGI API is fully
UNAUTHENTICATED — config read/write, relay fire, and userset.cgi itself
all return 200 with no credentials (verified on hardware). admin/admin
gates only the browser UI, and there's no inbound-auth setting (only
session_en, which bricks the read API). So the rotation is defence-in-
depth for the UI, NOT a boundary; the signed event log remains the real
anti-fraud guarantee. Verified rotation end-to-end on 10.0.10.5
(success &0&, wrong-old-pw &2&); device left at admin/admin.
The backend IP baked into a push-capable device at assign time is
auto-derived by subnet-matching a local NIC. That's non-deterministic
when two NICs match the device subnet, and null when none does. Surface
it: backendIpCandidates() lists all local IPv4 NICs (on-subnet first),
GET /api/setup/backend-ips serves them, and the wizard renders an
editable Backend push IP dropdown after a successful test (pre-filled
with the auto-pick, warns when no NIC is on the device subnet). The
chosen IP overrides the auto-pick on assign and is recorded in config.
Lock down the relay device for the flat (no-VLAN) network.
Relay control:
- pulseOpen/setRelay now use the Dingtian BINARY protocol (:60000) with a
relay password — the only relay option with auth (string :60001 has none, and
is kept only for the read-only status query). Frame verified on hardware.
HardenableDevice capability (driver harden()):
- set a random relay_pw (1-9999); disable unused channels (rs485/can/tcp x2/mqtt
-> p:255), keeping UDP1 binary (control) + UDP2 string (status).
- write-verified (device reboots on apply).
Assign/Save flow now does: fix preconditions -> harden -> set up input push;
the relay password is stored in lane_devices so the runtime device can command
the relay.
DELIBERATELY NOT touching the device's HTTP CGI session check (session_en):
enabling it on this firmware breaks the config-READ API (ECONNRESET) and locked
the backend out — required a factory reset to recover. The open CGI API is
accepted as flat-network reality; the signed event log is the real guarantee.
Verified end to end on hardware: assign hardens + configures the device, config
API stays reachable, pulseOpen with the stored password fires the relay, without
it is rejected. wiki: device-input-flow + dingtian-relay updated.
Two-step device setup so the admin verifies before committing — and never touches
the device's own web UI.
- POST /api/setup/test (admin-only): healthCheck + checkPreconditions, no save and
no device change. Returns device health + precondition issues.
- assign (Save) now also runs fixPreconditions (e.g. disables input_link_relay so
a button press doesn't auto-fire its relay) before configuring the input push.
Closes a gap where an assigned device could still auto-open. Fails the save with
no DB row if device configuration fails (no orphan/half-configured rows).
- SetupWizard: wires config fields -> Test connection (health badge + precondition
warnings) -> Save & configure; editing config resets prior test/save status.
Verified in-browser against the real device: Test -> ● ready + preconditions OK;
Save -> row persisted AND the device's Input Link URL written (push path matches
the saved device id). wiki/first-run-setup updated.
Secure the device→backend input push, and configure it automatically when the
admin assigns the device (no manual URL/secret entry).
Auth — HTTP Digest (chosen by hardware testing: the device can't push to a
self-signed HTTPS backend, but does Digest correctly; a URL token is sniffable/
logged):
- digest-auth.ts: MD5 qop=auth challenge/verify, single-use nonces (replay
resistance). Password never crosses the wire.
- push route: Digest + source-IP allowlist; per-device pushUser/pushPassword from
lane_devices. Still not behind the SPA cookie/CSRF auth (machine call). The
signed event log remains the real anti-fraud guarantee.
Auto-config on assign:
- setup assign: for push-capable devices, generate Digest creds, call
configureInputPush to write them + the push URLs to the device, store the creds
(password not echoed back). net.ts derives the backend IP on the device's
subnet (BACKEND_HOST_IP override).
- driver configureInputPush sets auth=2 + creds; PushConfig carries the creds.
- removed the earlier URL-token approach.
Two hard-won device-write bugs fixed in the driver:
- configApi now sets an explicit Content-Length — the device silently ignores
chunked request bodies (Node's default without Content-Length), so every config
write looked successful ({"status":0}) but did nothing. This was the root cause
of the session's "writes don't apply" mystery.
- #writeConfig polls until the change is verified, retrying (the device reboots on
apply; back-to-back writes were lost). The `pass` field caps at 31 chars, so the
generated password is 24 hex chars.
Verified on hardware: assign auto-configures the device; all 4 inputs then push
with Digest auth, zero failures. wiki/device-input-flow updated.
Neither UHPPOTE nor ZKTeco is used — the Dingtian relay controller was chosen
and verified. Remove their code and re-scope the wiki.
Code:
- delete access-uhppote.ts, uhppoted.d.ts, access.ts (zkteco/esp32-relay stubs),
and the three uhppote-*.mjs hardware test scripts.
- remove the `uhppoted` npm dependency from @parking/devices and @parking/server.
- unregister uhppote/zkteco/esp32-relay from the driver registry; drop their
exports. Catalog access drivers = dingtian only. Build green (5/5).
- refresh now-stale example comments (registry/interfaces/setup/api) to use
current examples; keep the two "UHPPOTE blocker" references that explain why
the precondition capability exists.
Wiki (kept pages, re-scoped):
- uhppote-controller, zkteco-controller -> rejected/historical with callouts;
uhppote-vs-esp32 -> historical (detection-vs-prevention lens still useful).
- re-point all "current device" framing (standing-decisions, bom, overview,
open-questions, device-registry, device-discovery, index) to dingtian-relay.
- transferable concepts (network-isolation, event-log-ingestion, barrier-not-a-
door, threat-model) untouched. Raw source immutable. Links lint clean.
Replace the dev-only token shim with real authentication.
Backend:
- @fastify/cookie; JWT carried in an HttpOnly + SameSite=Strict cookie
(parking_token), read from the cookie not the Authorization header.
- Double-submit CSRF: readable parking_csrf cookie + X-CSRF-Token header, both
cross-checked against a csrf claim baked into the JWT; enforced on mutations.
- Routes: POST /api/auth/login (bcrypt, constant-time-ish), POST logout,
GET me. requireRole now verifies the cookie + CSRF + role.
- seed-admin script (pnpm --filter @parking/server seed-admin) for the first
admin; no bootstrap endpoint.
- Removed SETUP_AUTH_BYPASS and catalog.authBypass entirely; setup endpoints
use the cookie admin guard like everything else.
Frontend:
- apiFetch wrapper: credentials:'include' + X-CSRF-Token on mutations.
- Login form; App gates on /api/auth/me and only shows setup to admins; logout.
- Wizard token field removed (auth is the session cookie).
Deploy:
- deploy/nginx.conf: prod reverse proxy, SPA + /api same-origin, TLS, so the
Secure cookies work. Dev stays same-origin via the Vite proxy.
Verified (curl + browser): wrong pass -> 401; login sets cookies; me -> admin;
assign without CSRF -> 403, with -> 201; no cookie -> 401; session persists
across reload. wiki/local-jwt-auth updated.
Brought up the real UHPPOTE controller (serial 225088491, fw 09120) end to end
and recorded a procurement-level blocker.
Verified on hardware:
- discovery (LAN scan), host-commanded openDoor on doors 1 & 2 (physically
actuated; reason="remote open door"), and live button capture
(reason="push button ok").
Driver/networking fixes (packages/devices/src/drivers/access-uhppote.ts):
- broadcast to subnet-directed address (lib doesn't enable SO_BROADCAST for the
global 255.255.255.255 -> EACCES);
- Config broadcast must match the target's subnet for unicast reply routing
(fixes the health-check timeout: 5s -> 24ms ready);
- discover across all local subnets, dedupe by serial;
- serialize all controller I/O (concurrent calls collided on UDP :60001).
Server/UX:
- load .env via node --env-file-if-exists (vars weren't being read before);
- SETUP_AUTH_BYPASS hardened: env-gated, dev + loopback only, fails closed
otherwise; surfaced as catalog.authBypass so the wizard drops the token field;
- .env.example documents all vars; inline favicon stops a 404.
- apps/server/scripts/: uhppote-listen (live events, restores prior listener)
and uhppote-relay (guarded door-open test).
BLOCKER (wiki/decisions/access-controller-button-flow.md): the controller's
push-button input auto-opens the relay in firmware with no report-without-open
mode, so ticket-first entry (button -> print -> open, fail-closed) is impossible
as wired. UHPPOTE can't do it on that input; ZKTeco *might* via a programmable
aux input + PULL SDK but that's unverified and needs a new driver. Entry-lane
hardware decision paused to focus on the business side.
wiki: access-controller-button-flow (blocker), zkteco-controller (stub +
assessment), uhppote-controller callout, index + log.
UHPPOTE controllers self-announce via UDP broadcast, but the frontend had no way
to find them — the admin had to type the serial blind. Add a generic discovery
capability and surface it in the setup wizard.
packages/devices:
- DiscoverableDriver capability + DiscoveredDevice type + isDiscoverable() guard
on the registry (optional, so any driver can opt in).
- uhppote driver implements discover() via uhppoted getDevices (UDP broadcast),
mapping each controller's serial/IP/firmware into a DiscoveredDevice; extract
shared buildCtx().
apps/server:
- GET /api/setup/discover/:driverId (admin-only): runs discover() and
health-checks each found device so reachability shows before assigning.
- catalog now returns a `discoverable` driver-id list.
apps/web:
- SetupWizard "Scan for controllers" button for discoverable drivers; lists found
devices with health badges; selecting one auto-fills serial + host. api client
gains discoverDevices().
wiki: new device-discovery concept; cross-link from registry/setup/uhppote;
note the broadcast-permission (EACCES) deployment caveat; index + log.
Verified: catalog flags uhppote discoverable; discover runs and fails gracefully
without hardware; non-discoverable driver -> 400; missing token -> 401.
Make the device-adapter pattern selectable so the admin chooses hardware at
install — per lane, from a catalog of supported drivers. Adding a device =
registering one more driver; no business-logic change.
packages/devices:
- interfaces.ts: AccessControlDevice / ReaderDevice / CameraDevice / PrinterDevice
(adds CameraDevice for entry/exit snapshot-on-event; access relay stays
intent-only per "a barrier is not a door").
- registry.ts: driver catalog with per-driver config fields + factory, config
validation, and a catalog payload for the setup UI.
- drivers/: stub adapters — access (zkteco, esp32-relay), reader (wiegand,
tcp-ip), camera (hikvision, dahua). Real vendor protocols TBD.
packages/db:
- lane_devices + setup_state tables (migration 0001); re-export query helpers.
apps/server:
- routes/setup.ts: GET /api/setup/catalog (public schema), and admin-only
/assign, /state, /complete with registry validation before persisting.
- extract auth.ts (requireJwtSecret, requireRole, JWT type aug).
apps/web:
- SetupWizard scaffold + api client: pick a driver per category for a lane,
render its config fields.
wiki: device-registry + first-run-setup concept pages; cross-link from
device-adapter-pattern; index + log updated.
Verified: full turbo build (5/5); catalog lists all drivers; admin assign
persists; missing-config and no-token requests are rejected.
