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. Claude-Session: https://claude.ai/code/session_01Xcm6ikLgGoCxxHrxtjkk5V
