Completes the anti-fraud/safety core coverage on a fresh in-memory DB:
- occupancy.test.ts (12): the ledger-fold count, the capacity/full gate, and the
reserved-subscriber-spots model — never double-count a parked subscriber, reserve
tightens only the TRANSIENT gate.
- pay-station.test.ts (12): quote math against the frozen tariff, the signed-payment
side effect (+ chain verify), no-session / no-tariff errors, the booth lookup view,
active-session listing.
- exit-flow.test.ts (9): the GATE — refuse unknown / unpaid / grace-expired (no exit
signed); a paid-within-grace session signs the exit; the booth transient path has NO
subscription bypass; a prepaid subscriber leaves via the assist (reopenBarrier) path.
- shift-service.test.ts (14): site-wide single-open invariant, the takings SPLIT by
source (subscription sales vs out-of-window vs transient tickets), drawer carry-
forward + cash_in/out vouchers, Z-report sign + listShifts read-back.
- entry-flow.test.ts (5): the exported validateTicketCode Luhn typo-guard. (The
capacity-gate/print-hold/sign-before-open paths need device fakes — covered in the
device + route phases.)
Adds test-helpers.ts (real EventLog, silent logger, tariff seeder). server 68/68 green.
Note: apps/vision has 2 PRE-EXISTING failures (test_app.py) — environment drift now
that fast_alpr + the ONNX model are installed (the "stub mode" assertions are stale).
Untouched here; to be fixed in the vision phase.
