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)
Money-moving fixes:
- Tip idempotency key regenerates when the tip amount changes after a failed
attempt (all 3 tip flows). Cached key still reused on same-amount retry
(dedup intact) and cleared on success/modal reset. Prevents silent
under-charge when a user retries at a different amount.
- Till replay path returns actual till_sales.status (may be 'pending') instead
of hardcoded 'completed' — no more misreported successful charge.
- BuyerEmail wired for CreateBookingPayment, gift card purchases, and till
sales (saved_card + online_square), matching the tip flow. Email lookup
errors logged, non-fatal.
- Till buyer-email errors now logged (was silently swallowed).
- on_the_house till top-up uses cached getIdempotencyKey() for retry-safe dedup
(was fresh crypto.randomUUID()).
Test/validation fixes:
- Add TestPaymentFromSquare_* unit tests (else-branch + nil card details),
build tag relaxed to 'test' so they run in the standard dev suite.
- Add TestValidateCardInfo table test (7 cases: both/either/neither/empty).
- Add TestCreateTillSale_TwoIdenticalCreateSales_BothSucceed regression test.
- Remove dead mock pre-registration in TestTipPayment_WithSavedCard.
- Correct misleading till regression-test comment.
ESLint cleanup (12 errors -> 0):
- Remove unused loadingCards in tip + pay-tip pages (dead assignments in
loadSavedCards).
- Scoped eslint-disable for {@html} in CardBrandIcon (hardcoded brand SVGs).
- Remove dead confirmSaveDefaultHours + unused rescheduleVersion prop in
WeeklySchedule (and its parent pass-through).
- Replace new Date() with SvelteDate in WeeklySchedule + BusinessHours.
- Fix each-block key in BusinessHours skeleton loader.
- Use void expression for reactivity-tracker reads in effects.
Restore processImage (images.go) and nonDepositPaymentType (handlers.go) with //nolint:unused — used in test files.
Fix 97 tx.Rollback defers to silently discard expected "tx is closed" error after commit.
Frontend: remove 44 unused shadcn-svelte files, 2 dead components, 9 stale npm deps, prune unused exports.

Track voucher_type_at_purchase on gift card creation. Apply VAT at gift card purchase (SPV), at redemption (MPV). Use transaction-aware GetCardByIDQuerier for till saved card lookups. Apply VAT to all booking payments (split records, terminal, tip, checkout). Add TotalVATAmount and TotalNetAmount to PaymentSummary responses.

Replace direct *pgxpool.Pool usage with PoolProxy wrapper across the entire backend:
- db.DB renamed to db.Conn (*pgxpool.Pool -> *PoolProxy)
- JWT functions now accept context.Context instead of using context.Background()
- Handler DB calls route through PoolProxy for per-test transaction support
- Fixture/helper/testdb functions accept Querier interface for decoupling
- Query ordering fixed in bookings handlers: COUNT after data query to avoid pgx conn busy
- Time truncation fixed: time.Date instead of Truncate(24*time.Hour) for week start calc
- testmain_test.go files updated with SeedBaseline and NewPoolProxy
