Gift-card rolling expiry (setting-driven, was dead config):
- GetGiftCardExpiryMonths(): single source of truth (business_settings
gift_card_expiry_months, fallback 24) shared by payment handlers and the
CleanupExpiredGiftCards job (was hardcoded 24).
- expiry_date now maintained on ALL 9 gift-card write sites (buy, topup,
transfer, redeem, terminal payment, refund credit, till) so the refund-time
guard at refunds.go actually fires. Schema default 12->24 + migration note;
test-DB seed aligned. Stale "expiry_date IS NULL" test rewritten; new
expired-card-rejected regression test.
Frontend SvelteDate purge (docs' stated convention, wide):
- All 180+ raw `new SvelteDate(...)` uses across routes/components replaced
with parseWallClockDate (backend UTC ISO) or new Date (wall-clock
constructors). SvelteDate imports removed. timeSlots.ts getDayWithOrdinal
fixed. Zero SvelteDate references remain; svelte-check clean.
Strict timezone/DST testing + QA fixes:
- 8 new hermetic boundary tests: clock.DST transitions (both 2026 folds),
closing-hours GMT vs BST, booking date-window midnight, refund-tier
elapsed-time independence, deposit-window UTC-instant, scheduling
LondonDateString midnight, today AT TIME ZONE window + UTC round-trip.
- today.go summary date labels fixed to London wall-clock (were showing the
previous UTC day during BST) + regression test.
- pgx ScanLocation fixed to UTC via AfterConnect (was host-local -> JSON
offsets depended on deployment TZ, contradicting the documented UTC
invariant) + regression test. Registered as a new *Type to avoid a data
race on the shared type map (caught by -race).
Admin Business Settings (setting now functional => legal floor):
- gift_card_expiry_months validation floor raised 1 -> 12 months (CMA/
Consumer Rights Act 2015 unfair-contract-term guidance) in endpoint + UI,
with rolling-expiry semantics shown in both display and edit form.
- 3 new expiry validation tests; 2 pre-existing message assertions updated.
Full suite 25/25 + race clean via run-tests.sh lockfile; svelte-check 0
errors/warnings; production build succeeds.
Add a Clock interface and default real-clock implementation so production code can use clock.Now() instead of time.Now(), and tests can inject a fake clock for deterministic timeouts and scheduling.
