N1 (HIGH) — BuyGiftCard concurrent same-key retry could double-issue gift
cards (2× value for 1 charge). Added pg_advisory_lock on the idempotency key
(mirroring the tip pattern) acquired before the idempotency check, so
concurrent same-key retries serialize and only one executes gift-card
creation.
N2 — Amount-equality guards in both reuse branches (CreateTipPayment and
BuyGiftCard). A same-key retry with a different amount now returns 400
instead of silently mutating the pending record's books/VAT/refund caps.
N3 — test coverage:
- TestBuyGiftCard_RetryPending_ReattemptsCharge: pending record + same-key
retry re-attempts, reuses the record (count=1), completes, and issues the
gift card exactly once.
- TestCreateCheckoutHTTP_DeviceOptionsWireShape: httptest.Server asserts
device_id is under checkout.device_options (not top-level). Extracted
createCheckoutHTTPWithClient for injectable base URL.
- MockClient.CreatePayment now dedups on idempotency key (paymentByKey map),
matching real Square behaviour.
N4 — Corrected the savepoint comments in handlers.go and giftcards.go: the
savepoint only exists in the test harness; in production db.Conn.Begin is a
plain tx and the status UPDATE runs on a separate pooled connection. Commit
is a harmless no-op in prod but required in tests.
Bonus bug fixed: CheckIdempotencyByKey scanned NULL booking_id/gift_card_id
(gift-card purchases) into plain string, failing with 'cannot scan NULL'.
Now uses sql.NullString.
Docs: Technical Manual.md:53 and Feature Catalog.md (2.1, 2.5) corrected —
no longer claim Web Payments SDK is live; new-card entry is documented as
pending P11, saved-card flow works via ccof tokens, dev mock rejects raw PANs.
CRITICAL — same-amount tip retry silently never charged:
- CreateTipPayment idempotency check now only short-circuits when the
existing record is 'completed'. A 'pending' record (previous Square call
failed) is REUSED and the charge re-attempted with the same key (Square
dedups safely), instead of returning the stale pending record as 200 with
a success toast and no charge.
- Same fix in BuyGiftCard: pending records trigger a re-attempt, not a
false-success response. Unique idempotency_key constraint means the
pending record must be reused, not re-inserted.
- Fixes the savepoint/rollback interaction: the nested tx (savepoint) is
now committed in the reuse path so the deferred rollback doesn't undo the
later status UPDATE on the same connection.
- Regression test: TestTipPayment_RetryPending_ReattemptsCharge verifies a
pending record + same-key retry re-attempts and completes, reusing the
record (count stays 1).
MAJOR — terminal checkout wire contract:
- device_id now sent as checkout.device_options.device_id (Square's required
shape), not a top-level field which Square rejects with 400.
- 'checkout pending' detection now uses typed sentinel ErrCheckoutPending
with errors.Is in both handlers, matching mock and real HTTP client.
MAJOR — exp_month/exp_year omitted from card creation payload when unset
(now *int with omitempty) — Square would 400 on 0/0; expiry comes from the
tokenized source.
Docs:
- README payments/infrastructure sections corrected (Web Payments SDK claim
replaced with accurate P11-backlog note; dev mock parity described)
- Future Work P11 updated to reflect raw-PAN rejection is now enforced in
both mock and prod (new-card flows are a documented dead end)
- Added plans/p11-square-web-payments-sdk.md: full implementation plan +
handoff prompt for the agent picking up P11 (Web Payments SDK nonces)

endpoints, component names, or implementation details.
Reflect new PUT /api/admin/bookings/{id} services endpoint, EditBookingModal
component, and updated test count (306/308). Mark handleEdit() stub resolved
in gap backlog.
- Add time blocker management for booking edit requests
- Add closing_time field to admin today/current-next endpoint
- Update UserBookingModal and CurrentAppointment UI components
- Fix fmt import in bookings_test.go (was missing)

- Add tests for guest account anonymization
- backend/handlers/bookings/admin_reserve.go:
- Add explicit reservation_type field ("walkin" | "callin") to request struct
- Remove TTL-based heuristic for type detection
- Walk-in: uses duration_minutes, allows null user_id, 1min past grace
- Call-in: requires service_ids, validates future time, calculates duration from services
- Both types now use 15-minute TTL
- backend/handlers/scheduling/time-blockers.go:
- Update CleanupOldReservations: both walkin and callin use 15min TTL (was 10min/60min)
- frontend/WalkInBooking.svelte:
- Full rewrite of reservation logic
- If available now and >15min remaining: reserve from now to slot end
- If <=15min or not available: reserve next full slot
- Always reserves before opening modal (never open without hold)
- Passes reservedDuration to modal
- TTL changed from 5 to 15 minutes
- frontend/WalkInCreateModal.svelte:
- Replace dead commented-out guest code with working guest creation
- Guest account created at submit time (not earlier)

enhance TestAccount_Delete to verify anonymization results

check; add HSTS and Referrer-Policy security headers; replace
http.ListenAndServe with http.Server + graceful SIGTERM/SIGINT shutdown
- frontend/routes/+layout.svelte: Replace alert() with toast notifications
for email verification flow
- frontend/routes/login/+page.svelte: Replace alert() with toast.info for
social login prototype buttons
- frontend/booking/BookingFlow.svelte: Remove 2 console.log debug calls;
add cancellation policy note in Step 3; add timezone policy comment
- frontend/ImageUpload.svelte: Comment out debug console.log
- init-scripts/init-script.sql: Add delete_guest_user() SQL function
- docs: Update README.md and Obsidian notes to reflect completed items
FIXES:
- Clarified that 1-hour minimum advance requirement applies to USER bookings only
- Admins can create walk-in bookings with no advance notice via AdminCreateBookingForUserHandler
- Updated test comments to reflect this distinction
NEW TESTS ADDED:
- TestAdminBookings_Create_WalkIn: Admin creates booking with < 1h notice (walk-in)
- TestAdminBookings_Create_WalkInWithDeposits: Admin walk-in with outstanding deposits + enforce_deposits=false
TEST SCENARIOS VERIFIED:
✓ User: Cannot book < 1h in advance (400 error)
✓ Admin: CAN book < 1h in advance (walk-in, 201 created)
✓ Admin: Can create walk-ins even with user deposits (with enforce_deposits bypass)
✓ Admin: Can bypass minimum advance requirement
BUILD STATUS:
✓ go build -tags test ./handlers/bookings
✓ go build -tags test ./handlers/admin
✓ go build -tags dev ./main.go
Documentation now clearly distinguishes:
- User journey: 1h minimum advance (universal)
- Admin journey: No minimum advance (accept walk-ins)
