Permissions matrix rethink (wiki/decisions/venue-modules.md §"Permissions matrix",
open-questions #16) — the grid stays the enforcement layer:
- Move 1: each desk's money is guarded by that desk's own permissions. Manifest
tillGuards {read, shift, cash}: booth = shift:read / shift:create / drawer:create
(unchanged), carwash = carwash:read / carwash:cash (new). Shift + drawer routes
resolve the guard FROM THE TILL (requireTill); a wash role holds no shift:* and cannot
touch the booth by construction. Replaces the session:read borrowing (tillPermission).
/api/shift/tills lists the role's readable tills with canWork; history/movements
without a till filter return the union of readable tills.
- Move 2: jobs — manifest permission bundles (booth-operator, booth-supervisor,
merchant, wash-operator) as one-click chips in Setup → Roles, with "mixes desks" and
"partial job" lints (warnings, never blocks).
- Move 3: the live WebSocket admits any watch permission (event/session/device read or
a module's feedPermission) and filters every push per role; report:read is the
reports screen only.
Auth: the token's roleId is only a hint — refreshRole() after every jwtVerify resolves
the user's CURRENT role (cached, bumped on role/user writes), so reassigning a user's
role applies on the next request and a deleted user's session ends with 401.
Tests: till guards + look-only role, feed rules, every job's permissions exist, role
reassignment without re-login. 353/353.

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).

Shift screen:
- The standalone ShiftControl block is gone from /shift. The open/CURRENT shift now
appears at the TOP of the shift list (CURRENT badge, live figures synthesized from
the X-report), unified with history. Selecting it shows its live activity log.
- Shift ACTIONS moved into the current shift's detail pane, each opening a MODAL:
End shift (confirm → signed Z-report result), drawer voucher (Mandat in/out),
takings-so-far (X-report). When no shift is open, a Start-shift button shows.
- The current shift's log auto-refreshes (5s); a closed shift is bounded by its
window. /setup/shifts stays read-only history (no manage props). Deleted the now-
orphaned ShiftControl.tsx.
Layout:
- Every screen is now full-width like /booth — stripped the per-screen
`mx-auto max-w-*` caps (Logs, Subscriptions, Plans, Tariff, Users, Roles, Setup
layout, Shifts). The shell <main> already provides padding.
Build+lint 12/12 (i18n parity). Verified a live open shift surfaces as the CURRENT
list entry.

Let the operator see, on demand during an open shift, the opening float
inherited, cash/card collected so far, pay-ins/pay-outs, and the current
expected drawer balance — without closing.
GET /api/shift/report (shift:read; 204 when no shift is open) returns the same
drawer projection the Z-report computes. Factored that math into a shared
ShiftService.#summariseWindow(open, asOf) used by BOTH the X-report (asOf=now,
read-only) and close()'s Z-report (asOf=endedAt, signed), so the two can't
drift. The X-report appends NOTHING — it's a snapshot, not an accountability
mark; the Z-report at close remains the signed record.
UI: a "Takings so far" button on the shift control reveals a cyan X-report
panel; the header still shows the live drawer total for the at-a-glance figure.
Verified against a copy of the live DB: X figures match drawerBalance(), the
drawer identity holds, zero events appended, chain still verifies.

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.

The TRM tokens were good but every screen hand-rolled inputs and buttons as
bare outlines on near-black panels, so fields, cards and buttons were
visually indistinguishable. Add a component layer (.input/.select/.textarea
as recessed slots, .btn family with a FILLED primary, .card scaffolding) and
adopt it across the booth/shift/login/tariff/site screens — several of which
were still light-theme inline styles dropped on a dark background.

Add react-i18next with two key-parity-checked catalogs (sq default/fallback, en).
Active language driven by the logged-in user's stored preference (applied after
/me resolves); SQ/EN toggle in the header persists via PUT /api/auth/language.
Translate the booth (screen, pay/exit modal, active sessions, snapshots, status),
Login, ShiftControl, SiteSettings, PermitManager, TariffComposer.
SetupWizard deferred (its content is server-provided; needs backend catalog i18n).
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.
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.
