julian a9ccf9e20c feat(carwash): Car Wash v1 + per-till shifts + site-level pay-at + till access by module permission
Car Wash — the pilot venue module (wiki/decisions/venue-modules.md):
- Master data (categories × services price matrix) at /setup/carwash; the desk at /wash
  (ticket lookup → order; open queue oldest-first: Done / Paid cash / Paid card / Void;
  Finished list). Orders freeze names + price; their life is signed (carwash_order,
  carwash_payment). Migration 0027.
- Where money is taken is a SITE setting (carwash_config.pay_at, migration 0028, signed
  config_change on a flip) — no per-order radio; a stale client is refused (409).
- Core seams: PayStation charge providers (a booth-paid wash rides the parking payment as
  chargeLines) + applyValidation() shared with the merchant route. A bay-paid, done wash
  signs the $0 parking payment so the exit reader releases the car.
- "Parking discount" modes for the wash: free while the wash runs (+ tolerance) and wash
  price off the fee (floored at 0), resolved at done and anchored at the order's intake
  (the entry-anchored version comped a 74-day stay); typed-amount and percent hidden for
  the wash. Long durations render y/d/h/m.

Tills — a shift belongs to a till, not the site (wiki/concepts/shift.md §Tills):
- TillId booth|carwash; every money event names its till (absent = booth, so the chain
  re-folds identically). ShiftService is per till: single-open, folds, X/Z-reports,
  vouchers, carry-forward. A bay payment needs the carwash shift.
- Working a till needs that till's module permission (manifest tillPermission; 403
  till_forbidden); /api/shift/tills lists only the role's tills.
- Web: ShiftButton per till (header = booth, wash desk = carwash); shift hub lists every
  open shift with till badges + filter; drawer hub switches tills.

Modules: landing per module (index route resolves booth → module landing → shifts →
profile); guards bounce to "/", /booth needs session:read.

Tests: carwash e2e suite (settings, intake, booth/bay paths, modes, void, gate, pay-at
policy, till permissions), 6 per-till shift tests; suite green (1 pre-existing flaky
backup test under the parallel run).

julian 23d6379be8 feat(modules): venue-module registry — entitled ∩ activated, requireModule, Setup panel
Groundwork for the Car Wash pilot (wiki/decisions/venue-modules.md, build-order
steps 1 + 3). No Car Wash code yet; validation is the first module behind the
seam, unchanged in behaviour.

- @parking/shared: MODULE_IDS, ModuleManifest, MODULES (parking required;
  validation dependsOn parking), parseEntitledModules / resolveModuleActivation
  / effectiveModules as pure functions.
- DB: site_config.modules_json (migration 0026, hand-written + journal;
  additive, nullable = everything entitled).
- Server: modules.ts (entitledModules from MODULES_ENTITLED env, activated
  from site_config, effective set, requireModule preHandler → 403
  module_disabled); modules/index.ts registers folder-based modules by
  iterating the registry (modules/validation); site-config GET exposes
  modules/modulesEntitled/modulesActivated, PUT takes the full desired set,
  enforces entitlement + dependency rules (400 with reason) and signs one
  config_change per module that actually flips; /api/auth/me carries the
  effective set; validation routes guarded requireModule → requirePermission.
- Web: lib/modules.ts + modules/{index,validation}; router.tsx spreads
  WEB_MODULES into nav + route tree (validate route no longer named there);
  Setup → Site "Modules" panel (required shown disabled, dependencies as
  hints, server refusal shown verbatim); validation sections + programs fetch
  gated on the module; App invalidates the router whenever the session
  changes (route-context consumers only re-read on navigation — the nav was
  stale after a flip, and after every other setUser too).
- Lavazh validation station retired (STATIONS = ["bar"]; rows untouched).
- Deploy: MODULES_ENTITLED=parking,validation explicit in both booth stacks;
  documented in .env.example.
- Tests: modules.test.ts (7); suite 329/329; web build clean; Playwright
  round-trip on /setup/site verified live.

julian 692dff5f89 feat(validations): merchant (bar/lavazh) ticket validations end-to-end
In-park merchants discharge customers' parking: a merchant user scans the
ticket on their device (/validate; validation:create + program↔user binding)
and applies their program — comp / first-N-minutes free / amount-off (capped,
typed at scan) / percent. All money stays at the booth: the quote folds live
validations in a canonical order (timeCredit → percent → fixed → comp, net
floors at 0, Σ lines ≡ gross − net), the payment records gross/discount and
CONSUMES the validation ids (an overstay's fresh period never re-applies
them), the receipt prints the gross → lines → net story, and the Z/X-report
carries discountTotalMinor leakage. Every apply/void is a signed, attributed
ledger event (refId = append-only void); program config is /setup/site master
data (Bar/Lavazh checkboxes + right-column panel, tabs when both) whose saves
sign config_change. Migration 0024 + reset-db drift-guard entries; 8 route
integration tests + priceSession fold suite.

See wiki/concepts/validation-discounts.md for the full design record.

julian 7649b897c4 feat(tariff): lab explains the sum — fee breakdown from the engine walk
"ALL 740 / 3h 2m" gave no derivation. explainFee in @parking/shared runs
the EXACT computeFee walk with an optional trace collector — one code
path, so Σ line items ≡ the amount by construction (golden V1 regression
byte-identical; instrumentation changes no fee). Items: contiguous
same-price increment runs (time window · N × unit · tier-card name),
window-package occurrences, stepped day totals (top-tier repeat
flagged), daily-cap clamps as NEGATIVE adjustments, entry grace.

/api/tariff/simulate returns `breakdown` (null when settled); the lab's
Outcome panel renders the lined table with a rounding note (raw min →
billed min at the increment — answers "why does 3h 2m bill as 4h") and
a total row. Works against active/historical versions and drafts alike,
so a night-package draft can be verified line by line before publish.
Largely delivers the wiki's open "composer price preview" item.

4 new engine tests pin the sum invariant + item shapes (97 shared green).

julian d9e6c13831 feat(tariff): whole-window package pricing mode (packageMinor)
A windowed card can now charge ONE total for any presence in its window —
the real night rate ("20:00–07:00 = 400, leave earlier and it's still
400"), which the per-increment flatMinor could not express (park-buzi's
"night 400" card billed 400/HOUR). Engine charges once per contiguous run
of increments the card wins, tracked across rolling-day segments so a
night crossing the 24h boundary charges once; out-of-window increments
price by the base card as usual.

Operator decisions (2026-07-05): per-occurrence repeat (two nights = two
charges), any-touch-pays-full, windowed cards only (a base "price per
day" is a 1-row up-to table). Validator: mutually exclusive with
flat/blocks/steps, no per-card cap, forbidden on the defaultCard.
flatMinor docs clarified as PER INCREMENT. 6 new engine tests.

julian 43c1f45e29 feat(reader): channel tagging (clone defense) + structural filter for phantom scans
Build desktop / desktop (push) Successful in 4m12s
Build & push images / images (push) Successful in 2m52s
CI / check (push) Successful in 42s
Two reader-hardening changes born from the park-buzi phantom-scan investigation
(empty pre-opening site, exit reader pushing sun-decoded garbage codes).

1. CHANNEL TAGGING — closes the printed-card-clone hole. The DT-008 push is
   channel-blind (one opaque cardid from either engine) and SubscriptionFlow
   matched by value only, so printing an RF card's UID (often written on the
   card face, e.g. 86A158) as a barcode cloned the card. Now:
   - Vendor tool sets output prefixes (QRCode "Q:", Card "K:"; server env
     overrides READER_QR_PREFIX / READER_CARD_PREFIX).
   - routes/qr-reader.ts strips the prefix and tags the read's confirmed
     channel (DeviceReadEvent.channel optical|rf; kind qr|card). Enrollment
     capture stores the BARE value. READ log lines carry ch=… (permanent
     phantom attribution).
   - SubscriptionFlow.match requires channel agreement: an optical decode may
     not claim an rf credential (and vice versa) — refused + signed
     sub.refused.channelMismatch anomaly (a clone attempt is a fraud signal).
   - Unprefixed reads keep the legacy untagged shape and match as before, so
     enforcement only bites where prefixes are deployed. Deploy server FIRST,
     then set prefixes in the vendor tool.

2. STRUCTURAL FILTER — phantom decodes out of the signed feed (operator-
   requested, reverses the earlier "record every probe" position — red
   "who is exiting?" rows for NOBODY train the operator to ignore the feed).
   read-dispatch.ts drops a no-match reader value that cannot possibly be a
   credential we issue (no ticket Luhn shape, no SUB-/SUBSESS- prefix, not
   confirmed-RF, not a plate) to UNSIGNED device_events telemetry
   (unrecognizedRead:true). Deliberately WIDE plausibility: forged ticket
   shapes, unknown physical cards, unknown SUB- codes all still sign the
   normal refusal anomaly; enrolled credentials match before the filter and
   can never be hidden. Works for legacy unprefixed reads too — the feed
   cleans up on deploy, before any vendor-tool change.

Wiki: dingtian-dt008-reader.md records the clone hole + fix, the filter (as a
recorded position reversal), and the two device-side settings now part of the
credential contract (output prefixes + Card Input format, moving 6H→8H at the
next vendor-tool session; both live ON the device — re-apply after any
factory reset/swap).

Tests: qr-reader-channel.test.ts (prefix split, route tagging, bare-value
capture), subscription-channel.test.ts (channel agreement matrix + anomaly),
read-dispatch-filter.test.ts (filter boundary: phantoms dropped, probes kept,
enrolled never hidden). Suite 278 green.

julian b4f1418858 fix(entry): enforce the camera press-gate + duplicate-ticket defenses
Field report (park-buzi): a BLINKING entry button still printed — the lamp
encoded blink-vs-solid (radar-only vs radar+camera) but #suppressReason only
checked the radar, so a radar false-positive (rain, pedestrian) minted a real
signed ticket. Three layered fixes:

1. CAMERA gate on the physical press: with an entry camera configured, a press
   is live only in the lamp's SOLID state (LaneStatus.entry busy, mirrored into
   EntryFlow via onLaneStatus). Suppress-only — the camera stays advisory (never
   opens, never traps). Camera-less sites keep the radar-only gate; a faulty
   camera is dropped via the existing bypassPresenceCamera admin toggle.

2. Cooldown as a REAL backstop behind presence: the presence branch returned
   early, so entryCooldownSec was dead wherever a loop was wired. Now it bounds
   the stationary-car double-ticket (a motion radar drops a motionless car →
   spurious loop-clear re-arms one-car-one-ticket → same car reprints).

3. Post-hoc duplicate-plate anomaly (entry-side twin of plateSwapSuspected):
   when entry ANPR recognizes a plate already OPEN under another session entered
   within ENTRY_DUP_PLATE_WINDOW_MIN (default 15 min), sign ONE
   entry.duplicatePlate anomaly naming both tickets for the operator to void.
   ANPR stays non-blocking (rides the post-open snapshot as before).

REJECTED: camera-vetoed re-arm (defer re-arm until the lane flips free). The
camera has no leave events — "free" is a ~30s silence timeout that never lapses
inside a queue, so every queued car after the first would be suppressed until
an operator intervened. Blocking legit entry at peak beats nothing; the proper
preventive fix is a pass-through sensor (passedInput) — recorded as open in
wiki/concepts/entry-double-press.md.

Also: setup.relayTest reason was missing from both web catalogs (parity is only
enforced sq<->en, so the build passed) — added.

Tests: entry-press-gate.test.ts (blink suppresses / solid prints / camera-less
unaffected / bypass honored / cooldown catches the dropout re-press / residual
risk documented / still-present re-press stays suppressed) +
entry-duplicate-plate.test.ts (flags open dup, ignores closed/stale/self/other
plates). Suite 258 green.

julian 6505a4a73b feat(entry): admin bypass of the presence gate for faulty radar/camera
Build desktop / desktop (push) Successful in 4m12s
Build & push images / images (push) Successful in 2m50s
CI / check (push) Successful in 41s
The entry button (physical press AND the operator-issued mint) requires
radar/loop presence + camera detection to confirm a real vehicle. When one
of those devices is faulty, the gate blocks legitimate transient entry. Let
the ADMIN drop a specific signal as a requirement until support fixes the
hardware — the admin is not the adversary, but weakening an anti-fraud gate
stays attributed and auditable:

- Granular: bypass radar and camera independently (Setup → controller
  section). A dead camera drops only the camera check; a dead radar only
  radar. Both off = normal gate; both on = press-to-print.
- Signed: a DEDICATED endpoint (PUT /api/site-config/presence-bypass,
  site:update) appends a signed config_change {setting, value, prev,
  operator} per actually-changed signal — new ledger type. No-op toggles
  sign nothing; disabling signs too. Kept out of the generic site PUT.
- Flagged: every vehicle_entry issued (and every refusal anomaly) while
  bypassed carries presenceBypassed:[...] in its signed payload.
- Persists until turned off; amber warning in Setup while active. The
  booth entry light treats a bypassed signal as satisfied (server
  re-checks authoritatively). Physical-button path falls through to the
  cooldown backstop when radar is bypassed.
- Migration 0020: two boolean site_config columns (default off).

Fixes a latent bug surfaced by the tests: firstRelayByDirection returned no
presenceInput, so issueForOperator's radar gate always read "presence loop
unavailable" — operator-issue never actually gated on radar. The resolver
now attaches the presence input serving the relay (mirrors relayForButton).

10 new tests: 5 gate combinations (each bypass drops only its signal +
records it), 5 route tests (RBAC, signed transitions, no-op, validation).

julian 306d136a08 feat(setup): operator-tested relay pulse, signed into the ledger
Add a per-relay "Test" control on each saved controller in /setup so an admin
can prove barrier wiring without a vehicle. POST /api/setup/test-relay pulses a
barrier relay — but because a physical open with no matching signed command is
the fraud signal, the route SIGNS a barrier_open_command (reason setup.relayTest,
source manual, attributed to the acting admin) BEFORE it fires. Reconciliation
then reads the open as explained, not an anomaly, and there's an audit trail.

- Admin-only (site:update), CSRF-guarded; fires only against a SAVED controller
  (real id → clean attribution; also stops a redirected/unsaved config from
  opening an arbitrary host's barrier). Sign-before-fire; a pulse failure is
  reported, not a 500. radarAlert relays (lamps) are excluded from the UI.
- New reason code setup.relayTest in @parking/shared (+ EN template); sq/en keys.
- EventLog constructed before setupRoutes so the route can sign.
- Integration test (stub controller, no hardware): RBAC 403, CSRF 403, signed
  barrier_open_command on success, 400 unknown relay w/ no ledger row, 404
  unknown controller, 400 bad relay value.

julian 33c4ea1e91 feat(entry): operator-issued entry + exit plate-swap reconciliation
Build desktop / desktop (push) Successful in 4m29s
Build & push images / images (push) Successful in 2m51s
CI / check (push) Successful in 37s
Two halves of one anti-fraud design.

(A) Operator-issued entry — when the physical entry button is broken, an
operator can issue an entry ticket so a real car isn't blocked out of the lot.
This hands the operator-adversary a mint, so it is:
  - PRESENCE-GATED like the physical button: a real car must be present (radar/
    loop AND camera busy). Enforced BOTH sides — the server re-checks current
    presence so a direct POST can't bypass a disabled button; no presence loop
    => feature unavailable; a no-presence attempt signs an anomaly.
  - FLAGGED: vehicle_entry source=manual + operatorInitiated + operator, PLUS a
    companion entry.operatorIssued anomaly (the adversary path always leaves a
    red-flag row).
  - capacity-OVERRIDE allowed but stamped lotFull (a broken button mustn't trap
    a legit car).
  New session:create permission (migration 0019 -> operator role, admin-
  revocable), POST /api/entry/issue (open-shift gated), EntryFlow.
  issueForOperator; the fraud-critical print->sign->open->snapshot sequence is
  factored into one shared #issueTicket (button + operator). UI: the entry
  BarrierLight becomes a clickable issue-control when presence+permission+shift
  meet (confirm -> issue).

(B) Exit plate-swap reconciliation — defends the ticket-swap fraud the mint
enables (paid car let out on a fresh $0 ticket, original ticket lingers
"inside", occupancy drifts up by phantom cars). The plate is the invariant:
ExitFlow.#reconcilePlateAtExit compares the exiting plate against all OPEN
sessions' entry plates, EXACT + HIGH-CONFIDENCE only (>=0.85; a fuzzy read never
gates — ANPR is advisory). On a match under a DIFFERENT ticket:
  - BOOTH path: returns swap_suspected + signs exit.plateSwapSuspected; the
    pay/exit modal shows a red warning + "Override & release" (override signs an
    attributed exit.plateSwapOverride). Flag+override, never a silent hard block
    (exit fails-open; a plate is never the sole gate).
  - READER path (no operator): log-only anomaly + fail-open.
  Extended BoothExitResult + /api/exit (override); boothExit client returns a
  structured swap result.

Verified: full monorepo build/lint/test green (229 server tests incl. 4 new:
hold-on-swap, override-releases-with-attribution, low-confidence-no-warning,
own-plate-no-warning). New wiki: operator-issued-entry.md +
plate-reconciliation.md; cross-linked from entry-exit-points, capacity-
occupancy, index. Preserves "a plate never OPENS a barrier alone — and now never
TRAPS a car alone either."

julian 114a32e6f2 feat(drawer): operator records cash movements, admin reviews after (own /drawer route)
Rework drawer cash movements from synchronous admin-authorization-at-creation
(operator typed an admin's password inline for every receipt/disbursement) to
operator-records-freely -> admin-reviews-after.

- New `drawer` resource: drawer:create (operator records; admin-revocable per
  role) + drawer:review (admin authorizes/denies). Migration 0018 grants the
  default operator role drawer:create; admin gets all in code.
- New signed `cash_review` ledger event { refId, decision, reviewedBy, note? }.
  A DENIAL is a FLAG, not a reversal: it never appends reversing cash and never
  touches the drawer balance (the correction is settled outside the app). This
  is what keeps a late review from leaking into the next operator's inherited
  drawer — a denial that lands after the reviewed shift closed moves no cash.
  Regression test: op1 disburses -> closes -> op2 inherits -> admin denies ->
  op2 drawer unchanged.
- Move the feature OFF the polluted /shifts route to a top-level /drawer
  (operator: record + own; admin: review queue + all). routes/drawer.ts lifted
  from routes/shift.ts (retired the authorizer-password gate; kept shift:cash
  for its other job = admin-sees-all-shifts). New DrawerManager.tsx.

Display fixes bundled:
- Render cash_review in the event-detail modal (decision / reviewed-by / note /
  movement ref) — previously showed nothing.
- Relabel the shift drawer figures for clarity: Daily takings / Receipts /
  Disbursements (was Cash payments / Cash added / Cash removed).
- Hide the Card figure everywhere when CARD_PAYMENTS_ENABLED is false (no POS
  on-site), matching the card-tender gate.

shared/db/server/web all typecheck; 225 server tests pass (incl. the drawer
review + cross-shift-leak regression); web build + i18n parity green. Verified
end-to-end via Playwright. Recorded in wiki/concepts/shift.md.

julian 0c218179c4 feat(backup): encrypted on-site DB backup engine + local target
The SQLite DB is the signed append-only ledger, so a disk failure / stolen or
destroyed PC means total revenue-history loss (open-question #5). This is the first
slice of the backup-recovery design: the engine + a local/mounted target + a daily
timer + a manual route.

Engine (apps/server/src/backup.ts):
- Consistent online copy of the live WAL DB via better-sqlite3's native .backup()
  (not a raw file copy, which can capture a torn WAL) — the restored copy is a
  byte-identical, queryable DB.
- AES-256-GCM with a scrypt-derived key from BACKUP_KEY; self-describing header
  (magic|version|salt|iv|...|authTag) so a restore tool needs only the key + file.
  Zero new dependencies (Node crypto).
- The plaintext intermediate is kept in scratch (not the removable/network target)
  and wiped in a finally, success or fail.
- Retention: keep-last-N + one-per-day within N days.

Wiring:
- BackupService (env config, single in-flight guard, last-success/last-error).
- routes/backup.ts: GET /api/backup/status (backup:read), POST /api/backup/run
  (backup:create), 409 when unconfigured. No restore route — restore is an
  out-of-band runbook action on a fresh appliance, not a console call.
- New  permission resource in @parking/shared.
- server.ts: an unref'd daily timer, a no-op until BACKUP_TARGET_DIR + BACKUP_KEY
  are set, deliberately not run at startup (a just-power-cut booth shouldn't write
  to a possibly-unmounted disk).
- openRawDb() added to @parking/db/testing (open a file without migrating, for
  restore-verification tests).

BACKUP_KEY is deliberately SEPARATE from EVENT_SIGNING_KEY (independent rotation;
backups travel, the signing key shouldn't). SMB/NFS work as mount paths; SFTP +
admin UI + restore runbook are deferred slices. Tests: round-trip byte-identical,
GCM tamper/wrong-key fail, short-key rejected, scratch cleaned, route auth/RBAC +
409. build/lint/test green (212 server tests). Wiki + open-question #5 updated.

julian 8a437d0c4b feat(booth): cancel wrongly-printed ticket (signed void) + refused-vs-anomaly display; fix CI uv
CI / check (push) Failing after 56s
Cancel a misprinted/test/wrong-vehicle ticket via a SIGNED `void` event — the
vehicle_entry is never edited/deleted (append-only). VoidFlow appends void{
voidedEntryRef, voidReason, operator, reasonCode:"void.ticketCancelled" }; route
POST /api/tickets/void gated event:void + open shift; reason REQUIRED. Refuses a
subscription / already-exited / already-voided / paid ticket (refund out of scope).
The void folds the session CLOSED everywhere it's counted — occupancy (count +
reserved spots), pay-station (lookup/activeSessions), exit-flow (#sessionFor), and
reports (excluded from entries) — so a voided car stops occupying a spot, can't be
paid/exited, and doesn't inflate "cars entered". No barrier action. Booth UI: a
"Cancel ticket" action in the pay/exit lookup modal (transient + unpaid + open;
gated on event:void) with a preset-or-free reason prompt.

Reclassify the Live feed: refused-action events (exitRefused/entryRefused/
permitRefused — e.g. a double card-scan, at-capacity subscriber, exit on a closed
session) are benign warnings, not red anomalies. event-detail.tsx now shows them as
amber REFUZUAR/REFUSED, reserving red ANOMALI for genuine red-flags. Display-only —
no ledger change, so historical events reclassify too.

CI: install uv + sync vision deps before the Turbo run. @parking/vision's lint/
typecheck/test shell to `uv run …`, but CI set up only Node+pnpm, so `uv run ruff`
failed ("uv not found") and broke the whole Turbo run. The Python checks pass once
uv provisions the toolchain.

- new: void-flow.ts (+ tests, 8) ; occupancy void-fold test
- shared: reason code void.ticketCancelled ; both web catalogs (sq/en parity)
- wiki: parking-session (ticket-void folds + guards, refused/anomaly split), log

julian 7680d9a0ed feat(recycle-bin): soft delete + restore for master data
Accidental admin deletes of users/roles/subscriptions/plans/tariffs were
hard and unrecoverable. Now they soft-delete into a recycle bin.

Schema (migration 0012): nullable deleted_at + deleted_by on users, roles,
subscriptions, subscription_plans, tariffs. Additive ADD COLUMN; verified
against a copy of the live DB.

Backend: each resource's DELETE route STAMPS instead of removing; every
catalog list filters deleted_at IS NULL. New recycle-bin module + routes
(GET /api/recycle-bin, POST .../restore, DELETE .../:id purge) gated on a
new recyclebin:read/update/delete permission. A 6-hourly + startup sweep
auto-purges items older than RECYCLE_BIN_RETENTION_DAYS (default 30; 0 =
forever).

Invariants: soft-deleted users can't log in (login rejects deleted_at;
no-lockout counts live admins only); a soft-deleted subscription doesn't
open the barrier; plans are versioned so a delete stamps all versions of
the plan_id (bin shows one item); username/role-name UNIQUE spans deleted
rows so reuse returns a clear 409 pointing at the bin; restore doesn't
auto-cascade a dangling role (guard resolves missing role to empty perms).
The signed append-only ledger is OUT of scope (no delete path).

Web: a Recycle bin tab under Setup (RecycleBin.tsx) with Restore/Purge +
purge confirm; api client + i18n (sq + en parity).

Tests: recycle-bin.test.ts (9 unit) + recycle-bin-routes.test.ts (4
integration: delete -> can't-login -> restore -> login, purge, gating,
409 reuse). server 103/103; build+lint+test 19/19.

Wiki: new concepts/soft-delete.md; local-jwt-auth + index + log updated.

julian 0985b86fa7 test(server): add fresh-SQLite test harness + anti-fraud core suites
Foundation for testing every service. Adds @parking/db/testing — createTestDb()
spins a fresh in-memory SQLite and applies the real Drizzle migrations, so server
tests run against the production schema with zero live-DB risk.

Wires Vitest into apps/server (test script + config; test signing keys via env)
and adds the first Phase-1 suites against the anti-fraud core:

- signer.test.ts (10): sign/verify round-trip, tamper + forgery rejection,
  malformed-signature guard, determinism, keyId rotation (buildVerifier).
- event-log.test.ts (12): monotonic index, prevHash linkage, payload-in-signature,
  append serialization, and verifyChain() catching every tamper class — edited
  payload, deleted row (index gap), broken prevHash, unknown keyId — plus
  canonicalize byte-stability.

Also stops *.test.ts leaking into shipped dist/ (tsconfig exclude in server +
shared; shared had been emitting compiled tests all along).

server 22/22, shared 87/87 green.

julian 8acef0464c fix(subs): price out-of-window charge from minutes actually parked, not a fixed entry stamp
An out-of-window subscriber entry stamped a FIXED windowOwedMinor = the whole
gap to window-open (e.g. 800 ALL for a 13:21 arrival to a 20:00 window) and
deferred it to exit. That over-charged anyone who left before the window
opened — a 1-hour visit was billed as 6.5 hours.

The amount isn't knowable at entry: a subscriber may enter early, leave after
an hour, come and go several times before the window opens, and linger past
window-close. They should pay only for the minutes actually parked outside the
window (capped at the window edges) — exactly what minutesOutsideWindow already
computes.

So the entry now stamps a MARKER only (outOfWindow: true + windowTariffVersionId
for reproducible pricing), no fixed amount. The exit gate and booth quote price
it live via windowOwedBetween(entry → settle-time), which already caps at the
window edges (early entry stops accruing at window-open; the in-window portion
of a crossing stay is free; the late-exit tail keeps accruing until payment).
Both already called that one function, so they agree.

- subscription-flow: entry stamps outOfWindow marker; the advisory slip is now a
  scannable out-of-window TICKET (Code128 + QR of the occurrence id).
- shared LedgerPayload: add outOfWindow; mark windowOwedMinor/windowGap*/
  windowCurrency deprecated read-only (historic signed events still type-check).
- BoothScreen: window-charge badge keys on outOfWindow (or the old stamp).
- ActiveSessions: drop the always-on "Open barrier" for subscribers — the
  assist-open / window-charge payment live in the pay modal, so the list can't
  one-click past an unpaid out-of-window charge.

Verified the live model on a DB copy: 13:21→14:30 = 200 ALL; 19:55(in grace)→
23:00 = 0; 19:00→21:30 (crosses into window) = 100 ALL. Existing signed
occurrences left untouched (immutable). build+lint 14/14, shared 87/87.

julian 294ca85ded fix(subs): out-of-window charge was a phantom 12h span (4,100 ALL bug)
The tariff-bridge owed amount summed TWO charges — the early-entry gap +
a "late-exit" gap — and the exit gap (outOfWindowGap edge:"exit") always
measured back to the PREVIOUS window close, even for a subscriber still BEFORE
their window. So a car that entered ~30 min early showed ~12h owed (4,100 ALL)
the moment it was looked up, instead of ~100 ALL.

Replace the two-gap sum with a single correct primitive,
minutesOutsideWindow(timeframes, tz, from, to): the minutes within the actual
stay [entry, now] that fall outside the allowed window (covering early entry AND
late exit, bounded by the stay, weekend/off-days free). windowOwedBetween prices
those minutes once as a transient stay (so increments + daily cap apply) against
the tariff in force at entry. Both the exit gate (subscription-flow) and the
booth quote (pay-station) now use this one source of truth — they can't disagree.

Verified on the live occurrence: was 4,100 ALL, now 100 ALL (9 min outside →
one increment). 87 shared tests (6 new regression cases incl. the phantom span).
Build+lint 12/12.

julian eafbc3ddbb feat(booth): badge subscriber out-of-window entries in the live feed
A subscriber entering outside their plan's allowed window gets a deferred
transient charge (windowOwedMinor, collected/gated at exit) — but it was
SILENT at the booth: the entry showed as a plain subscriber pass with no hint
money is owed, so the operator only discovers it at exit.

Surface it: add a "out-of-window — owes fee" badge on any entry/exit event
carrying windowOwedMinor > 0, so the operator sees immediately that this
subscriber owes a fee. Also type the window-charge fields on LedgerPayload
(were riding the open-ended index signature).

Behaviour is otherwise unchanged and correct — verified the live "Mon Kukaleshi"
entry: entered 20:29 local (before the 21:00 Mon–Sat window, grace 5m), owes
100 ALL for 18:29–18:55Z, stamped on the signed entry, still owed, gated at
exit. Subscribers get no ticket by design. Build+lint 12/12.

julian e0e218fa61 refactor: plan timeframes use a per-day-of-week picker (like the V2 tariff)
The timeframes model was a coarse weekday/weekend split, which couldn't express
"open Saturdays" or different rules on a specific day — and it didn't match the
V2 tariff, which already has a proper per-day-of-week picker (Hën–Die).

Replace PlanTimeframes { weekday, weekend } with { days[], fromMin, toMin }: the
allowed window applies only on the selected days (0=Sun..6=Sat; empty = every
day); on unselected days the subscriber parks free. A "night plan, free
weekends" is just days [Mon..Fri] with a 20:00→08:00 window — the exact case
from before, now expressible alongside any other day combination.

outOfWindowGap reworked to the days model (per-day membership test instead of
the weekend helper); the plans editor reuses the tariff composer's Mon-first
checkbox row and the shared tariff.dow0..6 labels. No production plans carry
timeframes yet (feature shipped today), so the shape changed directly with no
migration. Unit tests updated + extended (Saturday-only, every-day, weekday
night); 81 shared tests pass. Build+lint 12/12.

julian 53e1e7b25c feat: subscription v2 — quantity pricing, plan timeframes (tariff bridge), reserved spots
Three subscriber enhancements driven by real scenarios (migration 0011, all
additive columns — backward-compatible).

1. QUANTITY. One subscription covers N cars (a family pays once for two). Sale
   amount = span price × quantity; maxConcurrent defaults to the quantity so all
   N cars can be inside. Quantity rides in the payment payload.

2. PLAN TIMEFRAMES → TARIFF BRIDGE. A plan may restrict WHEN a subscriber may
   park (e.g. weekday 20:00→08:00, weekend all-day). A scan outside the window is
   NOT refused — the out-of-window minutes are charged at the normal TRANSIENT
   tariff (the subscriber is a transient for that time):
     - early entry: arrival → window-open, DEFERRED (signed as windowOwedMinor on
       the vehicle_entry payload), collected at exit;
     - late exit: window-close → departure, and exit is GATED
       (sub.refused.unpaidWindow) until paid at the booth.
   Pure, tz-aware outOfWindowGap in @parking/shared (12 unit tests); pricing
   reuses computeFee + the active tariff version
   (apps/server/src/subscription-window.ts). The exit refusal is a host-ONLINE
   business gate — the fail-open rule still governs the offline path.

3. RESERVED SPOTS. Site toggle reserve_subscriber_spots: occupancy holds
   max(0, quantity − itsCarsInside) per active subscription, so transients see
   "full" sooner; effectiveFree = capacity − count − reserved. Subscribers are
   never gated by full.

UI: quantity field + ×N quote (SubscriptionManager); timeframes editor
(SubscriptionPlansManager); reserve checkbox (SiteSettings); booth pay modal
shows an "OUT-OF-WINDOW" charge and takes payment to clear the exit gate.

Verified on a copy of the live DB: qty 2 = 2× price; a night-plan 19:30 entry →
30min/15,000 ALL owed, stamped + paid → gate clears, chain verifies; the reserve
toggle holds a qty-2 sub's 2 spots. Build+lint 12/12; 80 shared tests pass.

julian fd4608a8f1 feat: subscription plan catalog — config-defined pricing, dated spans, no typed amounts
Re-model subscription pricing from per-row, operator-typed prices into an
admin-composed, versioned PLAN CATALOG (the tariff pattern). The operator now
SELLS by picking a plan over a date span; the price is LOOKED UP, never typed —
removing the fat-finger risk on a money field — and day/week/month periods make
the hotel "guest stays 1–N days" case a daily plan over a check-in→check-out span.

- Schema/migration 0010: new `subscription_plans` (immutable, effective-dated,
  keyed by a stable planId; period day/week/month + per-period price + active
  flag). `subscriptions` gains planId/planVersionId; period enum widened. Seeds a
  "Monthly" plan from the existing site default price (no data loss).
- Pricing (pure, unit-tested in @parking/shared): periods = ceil(span / period),
  amount = periods × per-period price. Ceil = any started period is full (hotel
  practice). `resolvePlanVersion` picks the latest active version ≤ sale instant.
- Backend: new admin-only plan CRUD (`subscription:plan` permission); reworked
  sell path derives the amount from the plan; `POST /api/subscriptions/quote`
  returns a server-computed quote so the operator can't override it. The
  signed-payment sale fix is unchanged — only the amount SOURCE moved; payload
  now carries planId/planVersionId/periods. Updates never re-sell (price frozen).
- Frontend: SubscriptionManager sell form swaps the price field for a plan
  picker + start/end dates + a live quote line. New SubscriptionPlansManager
  (Setup tab) for the admin catalog. i18n (sq+en) for both.

Verified on a copy of the live DB: 0010 applies (existing subs intact), a
3-night hotel sale prices to 2,400 ALL, appends one signed payment with
planVersionId, chain verifies. Build+lint 12/12; 68 shared tests pass.

julian 2835f78635 feat: re-model drawer cash as directional vouchers (Mandat Arkëtimi / Pagese)
Replace the single signed-± cash_movement with two distinct financial
documents — the direction is the event TYPE, not the sign of an amount:

  cash_in  = Mandat Arkëtimi (receipt / pay-IN,  +)  voucher AR-NNNN
  cash_out = Mandat Pagese  (disbursement / pay-OUT, −)  voucher PA-NNNN

Each carries a positive magnitude, voucher number, reason, the operator who
raised it and the admin who authorized it, and prints an Albanian slip.

Authorization changes from admin-only to operator-RAISED / admin-AUTHORIZED:
any shift:create holder raises the voucher, but POST /api/cash-voucher only
commits when authorizedBy is a real admin (shift:cash) re-entering their
password (verified server-side). Keeps the float control while letting the
operator do the booth paperwork.

Legacy cash_movement events are kept — they still verify and still fold into
the drawer (signed-±); the append-only chain is never rewritten. The drawer
fold and the Z-report window now sum all three types.

Verified against a copy of the live DB with the real signing modules:
cash_in 3000 + cash_out 5000 → drawer −2000, hash-chain verifies OK.

Resolved at serialize time (new plate-lookup.ts; prefers an entry read;
one device_events scan per page) like subscriber-name enrichment — the
signed ledger is untouched. Adds plate? to the shared LedgerEvent and to
ActiveSession/SessionLookup; a small amber badge in the UI.

Caveat: a vehicle_entry is signed + pushed over WS before the async ANPR

julian 9a1feeeb20 fix(tariff): reject stepped base combined with time/seasonal tiers
A stepped ("up-to") default card prices the whole stay as one total, so the V2
engine short-circuits to steppedFee and NEVER consults windowed cards — any
time/seasonal tiers would silently never fire. Found live: an active tariff had a
stepped base plus weekday-night + weekend tiers, and every 3h stay priced 600 ALL
regardless of hour/day because the tiers were dead.

- validateTariffV2 now rejects a stepped defaultCard combined with windowedCards,
  with an actionable message (switch the base to ladder/flat, or remove the tiers).
- Composer shows an inline red warning the moment base mode is stepped and tiers
  exist; publishing is blocked server-side regardless.
- ApiError now carries the server's problems[], so the publish error surfaces the
  SPECIFIC reason instead of a generic "invalid tariff structure".
- 2 new validation tests (55 pass).

julian cc507f490f feat(tariff): stepped ("up-to") pricing mode — total-by-duration
Owners often state rates as a total-by-duration matrix (0-1h=200, 0-3h=500,
0-6h=800, 0-9h=900, 0-12h=1000) that the marginal hourly ladder can't express
(the ladder sums per-increment rates; this is cumulative totals at thresholds).
Add STEPPED as a third pricing mode alongside the ladder and flat.

- @parking/shared: TariffStep {uptoMin, totalMinor} + a `steps[]` field on V1
  structures and V2 cards (mutually exclusive with blocks/flatMinor). steppedFee():
  smallest tier with uptoMin >= duration wins (INCLUSIVE boundary), the top tier
  repeats as a per-day cap; wired into computeFeeV1 + computeFeeV2 (V2 default card
  only — a whole-stay total can't be sliced per-increment by a windowed card).
  Validation: ascending uptoMin, non-negative totals, no daily-cap-with-steps,
  steps-only-on-default. priceSession/quote/booth/Lab price it via the shared core.
- Composer UI: a "By duration (up-to)" mode with an up-to/total table (base card
  only). i18n modeStepped/steppedHint/stepUpTo/stepTotal/addStep (sq+en).
- 8 new unit tests incl. the exact owner matrix, multi-day repeat, overstay, and
  validation (53 pass). Verified end-to-end via the UI: authored + published the

Test rates "in time" (overnight windows, daily caps, overstay) in seconds against

- Extract priceSession() into @parking/shared: the grace/overstay wrapper over
  computeFee (unpaid -> entry..now; within-grace -> settled 0; grace-expired ->
  overstay, a fresh period from grace-expiry). PayStation.quote() now calls it so
  the booth and the lab can never diverge.
- API (tariffs.ts, tariff:read, read-only): POST /api/tariff/simulate prices a
  hypothetical session (active/any version/inline structure) and returns the
  priceSession outcome + a 30m..3d duration curve (see where the daily cap flattens);
  GET /api/tariff/simulate/session/:identity prefills from a real ledger session.
- UI TariffLab.tsx at Setup -> "Tariff Lab": version picker, entry/asOf times,
  optional payment+grace, category, and load-a-real-ticket. Admin-gated, available
  on-site (useful to quote a dispute).
- 4 new priceSession unit tests incl. the ticket-1245791632490 overstay-not-zero

julian 30e7fe85de feat(booth): refusal snapshots, subscriber access medium, one-car-one-ticket entry
Three booth-integrity improvements that share the entry/exit flows and activity log.

Refusal snapshots: previously only an accepted open captured a camera image; now
every refusal/hold anomaly fires the directional camera too (a turned-away car is
exactly the evidence wanted) — entry refused-full/held, exit refused
closed/no-session/unpaid/grace-expired (booth + reader paths), refused subscription.
A refused entry has no ticket id, so a synthetic REFUSED- ref keys the anomaly + photo
together. Same fire-and-forget contract; failed captures still show as tiles.

Subscriber access medium: the subscription flow already signed `via`
(qr|card|plate) into entry/exit payloads; surface it as a typed LedgerPayload.via, a
cyan chip in the ticker, and an "Entry medium" modal row (sq+en). Display-only.

One car = one ticket: the entry button could be mashed to mint many tickets per car
(corrupting occupancy + enabling ticket-shopping at exit) — the old #inFlight guard
only blocked overlapping presses. Add a per-relay guard configured on the relay spec:
PRESENCE mode (presenceInput ties ticketing to a vehicle loop on a Dingtian input —
one ticket per car, re-armed when the loop clears) or COOLDOWN fallback
(entryCooldownSec) when there's no barrier feedback. A suppressed press is unsigned
device_events telemetry, not a signed anomaly. SetupWizard exposes both fields.
Fail-closed entry and barrier-is-not-a-door invariants untouched; guard state is
in-memory/rebuildable, starts armed after restart.

Add a third data stream (app_logs), distinct from the signed ledger and device
telemetry, for operational/diagnostic logs — an offline appliance has no Sentry to
ship to, so the host is the log store.

Backend: a pino stream tees warn/error/fatal into app_logs (info/debug stay
stdout-only) with no call-site change; the DB is built before Fastify so the logger
has its sink. Frontend (lib/logger.ts): ships failed API requests (minus 401 churn),
window.onerror, unhandledrejection, and a top-level React ErrorBoundary; console
warn/error forwarded only at debug/trace. Batched/throttled POST, sendBeacon on
pagehide, loop-safe (never logs the /api/logs call), best-effort everywhere.

POST /api/logs (any signed-in user, CSRF, tolerant) + GET /api/logs gated by a new
log:read permission (new `log` RBAC resource; admin holds it). Retention: pruned by
age + row cap, hourly + at startup. UI: a Logs screen under /setup (filter
level/source/since, expand to context+stack), sq+en. Migration 0009_app_logs.

julian f31e57b4ae feat: explainable activity log — reasons, subscriber names, snapshot gaps
The live activity feed flagged anomalies with no explanation and showed
opaque session keys. Make events self-describing and clickable.

- Clickable feed rows → read-only event-detail modal: humanized fields,
  entry/exit snapshots, and signed-chain provenance collapsed behind an
  audit disclosure (operator sees the story, auditor expands for crypto).
- Localized reason codes (backend i18n): the signed ledger now carries a
  stable REASON_CODE + params (+ English fallback) instead of free-text
  English. The UI translates via reason.<code> catalogs in sq/en, so an
  Albanian operator reads Albanian — from the same immutable event. Adding
  a language is a catalog change, no re-signing. (@parking/shared
  REASON_CODES, reasonPayload; entry/exit/subscription flows emit codes.)
- Subscriber-name resolution: a SUBSESS-… occurrence now shows the
  subscription holder's name (fallback "Abonent"/"Subscriber"). Resolved
  read-time server-side (events API + WS push) as a non-signed
  subscriberLabel; cached with invalidation on subscription edit/delete.
- Failed-snapshot visibility: a camera that was attempted but unreachable
  now shows a "⚠ camera unreachable" tile instead of a silent gap. The
  snapshots API returns failures[] from telemetry, filtered so a recovered
  capture shows no stale warning.

julian d0841c8601 feat(auth): dynamic RBAC — composable roles + resource×CRUD permissions
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).

julian cf1ff5676d feat(tariff): V2 — legacy-parity pricing (time-of-day, category, seasonal, flat)
Bring the legacy ParkSQL2017 pricing BREADTH onto our engine while keeping
integer-minor-unit money + immutable signed versions (rejecting legacy's
float money / mutable rows). TariffStructure becomes a discriminated union:
V1 = the original bare ladder (UNCHANGED, verbatim algorithm, golden-
regression-tested against the live version); V2 = {version:2, tz, shared
knobs, defaultCard, windowedCards[]} where each card is flat OR a block
ladder and may be scoped by wall-clock hour window / day-of-week / date
range / vehicle category.

computeFeeV2 prices by stepping one increment at a time, advancing the
ladder by ELAPSED minutes (continuous) while selecting the active card by
WALL-CLOCK time in the version's FROZEN tz. Decisions: tz is a per-site
setting (site_config.timezone, default Europe/Tirane) stamped server-side
into each version on publish — never the host clock (reproducibility);
default-card cap governs a mixed day; precedence = specificity
(date>dow>hour) -> priority -> name (total, order-independent), validation
rejects ambiguous ties; category = a card FIELD, frozen in the signed
vehicle_entry payload (site_config.default_vehicle_category default), read
at both pricing call-sites.

Composer: default card front-and-centre (flat/ladder toggle), tiers under
an "Advanced" disclosure; emits BARE V1 when no tiers (back-compat). DB:
migrations 0005 (timezone) + 0006 (default_vehicle_category). Stood up
vitest in @parking/shared (was zero tests on the ledger-feeding fee fn);

julian dfa76346d6 feat(tariff): complete the progressive ladder — require open-ended last block, hours-based composer
The stepped-block engine already does "first N hrs x X, next N hrs x Y, ...,
24h cap" (ordered blocks, per-block rate, rolling-24h cap). No new axis; this
completes the model and removes its footgun.

- validateTariffStructure (shared) now REQUIRES the last block to be open-ended
  (uptoMin: null). A bounded final block silently inherited its own rate past
  its bound (a hidden, never-stated price — e.g. the live ALL tariff billed
  hour 4+ at the 3rd-hour rate). rateAt() still prices legacy bounded-tail
  versions; validation is publish-only, so published immutable versions are
  unaffected (no migration).
- TariffComposer edits bands as a DURATION in hours ("first 2 hours, then next
  3 hours"), accumulated into the engine's cumulative uptoMin (minutes) on
  submit. The last row is a pinned, non-removable "thereafter (open-ended)"
  band, so a published card always satisfies the open-ended-last rule.
  blocksToForm round-trips stored minutes back to band hours (legacy loads).
- i18n: replaced upToMin/egExample with bandDuration/hoursUnit/egHours (sq+en,
  catalog parity green).

Verified: validator rejects bounded-last / accepts open-ended; computeFee
correct at 1/2/3/5/6/24h for a 0-2h@200,2-5h@100,5h+@50 + 1000 cap card. Full
build green. Wiki (tariff.md, log.md) updated.

julian 50a3095ef3 feat(shift): cash drawer balance carried across shifts + admin cash movements
New signed cash_movement event (admin-only): load/remove drawer float, signed +
attributed. ShiftService folds cash payments + movements by time into a drawer
balance; shift open auto-inherits the prior shift's expected closing drawer as its
opening float; the Z-report reports opening/taken/added/removed/expected (= next
shift's opening float). Card payments excluded (settle to bank). Routes: POST
/api/cash-movement, drawer in GET /api/shift/current. ShiftControl shows the live
drawer + admin load/remove form + Z-report drawer block. Wiki: shift.md.

julian 644bfa1462 server+web: shifts — open/close + signed Z-report (manned mode)
A shift is two signed ledger events, no mutable table: new shift_open event
type + existing shift_z_report. The operator is the logged-in user (carried in
event identity); a shift is open iff their latest shift event is a shift_open.

ShiftService: close sums payment events in [start,end] by tender (cash/card, by
payment time), appends the signed shift_z_report (totals/counts/window), and
prints via a new generic PrinterDevice.printReport(title, lines) (Rongta ESC/POS
text) to a booth-receipt printer. Print is best-effort — a failed print does not
undo the signed close.

Routes (cashier/operator/admin): GET /api/shift/current, POST /api/shift/open
(409 if open), POST /api/shift/close (409 if none). Web ShiftControl in the
shell (non-readonly): Start/End + Z-report totals.

Verified: open -> double-open 409 -> payments (cash+card; one outside the window
excluded) -> close totals correct + signed + printed -> close-again 409 ->
re-open ok; readonly 403; verifyChain ok.

julian b4d0dfadd6 tariff composer: admin publishes rate-card versions (pay station now operable)
validateTariffStructure (shared): non-negative ints, ascending block bounds,
only the last block open-ended — a malformed card can't be published.

Routes: GET /api/tariff (active + history, any signed-in role), POST
/api/tariff/versions (publish an immutable, effective-dated version; admin
only). The single site tariff row is created lazily. Editing = publish a new
version; past sessions keep their pricing.

Web: TariffComposer in the admin shell — edit currency, grace windows,
increment, daily cap, lost-ticket fee, and add/remove rate blocks (major-unit
input -> minor on submit); shows active version + history.

Verified via inject: empty -> active null; invalid blocks -> 400 with problem;
valid -> 201; readonly publish -> 403; after publishing, the pay station quote
returns 404 (no session) instead of 409 (no tariff) -- it now prices against the
active card.

julian f18e28eeca server: pay station + fee calc — full transient loop now passes
computeFee() in @parking/shared: pure integer fee over a TariffStructure
(stepped blocks, rolling-24h cap). Two edges fixed under test: grace uses RAW
duration (not rounded-up minutes), and the block ladder resets each 24h day.

PayStation + routes (GET /api/pay/quote, POST /api/pay): look up the open
session, resolve the active tariff version (latest effectiveFrom <= entry),
computeFee, append a signed payment event (amount/currency/tender/
tariffVersionId/graceExitMin). overrideMinor handles lost-ticket/dispute. PCI
stays out of the app: tender only records cash/card.

Verified end to end: entry -> quote (300 for 90min) -> pay -> exit opens and
closes the session, verifyChain ok.

julian 8c2cf93067 db: business-layer schema — ledger/device event split, tariffs, permits, sessions
Implements the wiki design in packages/db + packages/shared.

Event split: rename events -> ledger_events (signed business ledger) and add
device_events (unsigned telemetry). ledger_events gains a signed JSON payload
(amount/tariffVersionId/sessionRef/tender…) + keyId; canonicalize() includes
the payload via sorted-key serialization so business data is tamper-evident.
Raw Dingtian input now writes device_events, not a signed input_received.

New tables: tariffs + immutable tariff_versions (composable/versioned, currency
+ FX-ready), permits (+ permit_credentials, permit_plates; maxConcurrent default
1), blocklist, sessions (rebuildable projection cache — not a source of truth).

shared: split ParkingEvent/Type into LedgerEvent/LedgerEventType + DeviceEventKind;
add LedgerPayload, Tender, TariffStructure/TariffBlock.

Regenerated a single baseline migration (no production chain data existed).
Verified: chain appends + verifyChain ok; tampering a payment payload breaks
the signature. Full repo builds (5/5).

julian add5fc0166 Append-only signed event log; persist Dingtian input pushes
Implement the core anti-fraud primitive: an append-only, hash-chained,
signed event log (the schema + types predated this; the writer/signer are new).

- EventLog (apps/server): serialized append, monotonic index, prevHash chain,
  signature; verifyChain() detects tamper/reorder/delete. No update/delete paths.
- Signer abstraction (packages/shared) over the ATECC608 secure element, with a
  SoftwareSigner (HMAC, EVENT_SIGNING_KEY) shipped now since the chip is still
  open-question #6. Documented: software signer is tamper-evident but NOT
  unforgeable-by-owner.
- Add ParkingEventType "input_received" for raw device inputs (not yet a
  vehicle_entry, which the entry flow will append later).
- Read API: GET /api/events; integrity self-check: GET /api/events/verify (admin).

Verified on hardware: shorting the Dingtian inputs produced signed, chained
input_received events; verifyChain ok; direct DB tamper/delete detected.

NOTE: the log captures host-originated actions only. Out-of-band relay
actuation (sniffed relay_pw, string protocol, ip_watchdog) produces no event
by design -- the control is reconciliation vs. an independent witness, which is
not yet built. See wiki/concepts/append-only-event-chain.md.

julian bfe64032d8 Initial scaffold: Turborepo monorepo + design wiki
Turborepo (pnpm workspaces) with all dependencies pinned to latest
mutually-compatible versions: turbo 2.9, TypeScript 6, Fastify 5,
React 19, Vite 8, better-sqlite3 12 + Drizzle ORM 0.45.

Layout:
- apps/server   Fastify backend (local JWT auth + role guard, /health)
- apps/web      React 19 + Vite 8 operator SPA
- packages/db   Drizzle schema on SQLite/WAL; append-only events + users
- packages/devices  reader/printer/relay adapter interfaces (intent-only relay)
- packages/shared   shared domain types

Architecture constraints from the design wiki are encoded in the scaffold:
append-only hash-chained + signed event log, device-agnostic adapters,
"a barrier is not a door" (relay expresses intent only), fully-local
offline-first auth.

wiki/ is an LLM-maintained Obsidian knowledge base (28 pages) ingested
from the architecture & design notes, with its own maintenance schema.

Verified: pnpm install, full turbo build (5/5), server boots and serves
/health, drizzle-kit generates the initial migration.
