popertotsandSisyphus e9b34d0ad6 fix: dev-mock/prod parity + fail-closed config gates — 402 verification, cnon:sca binding validation, refund reconcile parity, SNAPSHOT_ENC_KEY fail-closed, webhook config gates, access-token startup validation, ClientIP validation 
- mock: 400->402 for CARD_DECLINED_VERIFICATION_REQUIRED, cnon:sca- tokenize-result binding validated (prefix/amount/deny), RefundPayment exact-amount reconcile parity, ReplayPaymentByKey snapshot sanity, verify_mock_ legacy widening removed, listRefunds zero-time omits begin_time
- main.go: SNAPSHOT_ENC_KEY log.Fatalf in non-mock, webhook key-set-URL-unset log.Fatalf, SQUARE_ACCESS_TOKEN/LOCATION startup validation, empty-env base URL matches 2FA production interpretation
- mw: ClientIP rejects garbage/comma/port XFF values, documented trusted-proxy requirement

popertots d25ba16aa7 feat: Square SCA tokenize-result wire contract — token as source_id, byte-identical dev mock 
The CURRENT saved-card SCA contract (Square card.tokenize(verificationDetails,
cardId)) returns a one-time tokenize-result that must be sent as the charge
SOURCE (source_id), not a separate verification_token.

- square_dev.go: the mock validates the WIRE BODY (mockPaymentWireBody — an
  independently assembled copy of buildCreatePaymentBody) so it accepts exactly
  the request shape the real client emits. SimulateSavedCardVerificationRequired
  now demands SCA on every saved-card charge in both wire shapes: (a) a genuine
  tokenize-result (cnon:sca-... — isSCATokenizeResultSource) as source_id +
  customer_id is ACCEPTED (the token IS the buyer verification); a RAW
  card.tokenize() nonce in the tokenize-result slot is REJECTED
  CARD_DECLINED_VERIFICATION_REQUIRED (money-F2 — the mock is the enforcement
  point that stops the forged shape); (b) legacy ccof: + verification_token is
  kept for backward-compat.
- square_http_client.go: byte-identical body assembly shared with the mock, so
  TestCreatePayment_SCA_SavedCard_WireBody_ByteIdentical pins the mock and the
  real client emit identical CreatePayment bodies (a wire drift fails the test
  before reaching prod).

popertots 6d82535780 fix: adversarial review round — replay-rescue double-charge, discount credit, 2FA/per-IP limits, snapshot encryption, refund reconciliation, VAT, frontend parity, tests+docs 
Addresses the adversarial fresh-eyes audit (findings A1-A20) plus review-round fixes:
- CRITICAL A1: replay-by-key rescue cross-checks replayed CreatedAt; ccof blind-fail leaves pending with CRITICAL + notification instead of clawing back
- A2/A3/A4: till idempotency key restored to unconditional hash; tip rejected in CreateBookingPayment; campaign discount now reduces the charged amount (deposit credit)
- A5: admin notifications on blind-fail, manual-refund re-arm, cap-stranded charge-group, webhook FAILED/REJECTED refunds
- A6/A10: BuyGiftCard idempotency user-scoped; gift-card slot scan advances past failed rows
- A7/A14/A15: 2FA user+IP limiter, SNAPSHOT_ENC_KEY startup validation, accurate pepper/log-delivery docs
- A8/A9: snapshot encryption on all write+reuse sites; MPV->SPV effective voucher type (single VAT point)
- A11/A12/A13/A16: amount-aware refund reconciliation; completed-booking refund re-validation; till retry dedup; PaymentWasRefunded on SquareClient interface
- A17/A18/A19/A20: CI runs npm test; confirm_overflow_tip frontend dialog; unknown-event admin notification; mock token redaction
- M7 ConfirmOverflowTip, M9 snapshot encryption, C1 discount ordering regression test
- Frontend vitest framework (41 tests), backend coverage for fixed functions, docs corrected (2,269 tests, SUPPORT_EMAIL tokens, resolution status)

All 25 backend packages pass; frontend 41/41; build + env-docs green.
 2026-08-22 00:34:50 +01:00
popertots 5cc5a7f6d2 fix: review round 7 — fresh-eyes audit fixes (6 agents) + full test suites for every backend change 
Fresh-eyes review round with 6 independent agents (money-safety, concurrency,
Square wire parity, security, frontend flow, testing-gaps). Every finding was
independently verified against the code before fixing. All backend changes
now carry full test suites (10+ new tests, each verified to FAIL without its
guard). All 20 packages green, race detector clean.

Money-safety:
- Gift-card purchase refunds no longer create money: manual refunds of a
  no-booking (gift-card purchase) payment are rejected with a clear message
  in the direct handler AND never re-issued by the sweep-resume path
  (processManualPaymentGroup skips them; reconcile-then-fail, no re-issue).
- BuyGiftCard no-client-key fallback: derived deterministically under the
  advisory lock (pending-row reuse fixes lost-response double-charge;
  completed-row sequence advance preserves distinct-purchase collapse fix).
- Terminal completion is never unrecorded: activeTerminalCheckoutID now calls
  recordUntrackedTerminalPayment when a provisional (tmp-) checkout is found
  COMPLETED at Square (previously only marked the row COMPLETED — a lost poll
  left the payment invisible and unrefundable).
- Sweep: provisional tmp- checkout rows are resolved against Square first
  (COMPLETED → record; live → keep guard; NOT_FOUND/CANCELED → fail;
  ambiguous → leave pending) instead of blind-failing a possibly-live
  checkout. recordUntrackedTerminalPayment re-checks the booking status
  (FOR UPDATE) and refuses to record on a cancelled booking, inserting a
  critical_payment_log admin notification instead. Till-sale post-charge
  UPDATE now requires status='pending' (no resurrection of a clawed-back sale).

Frontend (Svelte 5):
- UserPaymentModal keeps CardSelection mounted through processing (bind:this
  ref + Square iframe survive the loyalty/tokenize awaits) — new-card
  payments work again.
- BookingFlow clears the cached nonce/verification pair on any failure (retry
  re-tokenizes fresh; idempotency key retained for dedup); 409 'already paid'
  refetches the booking and reconciles depositPaid so the confirmation gate
  opens; Back button disabled during processing.
- Synchronous double-submit guards on buyGiftCard/redeemGiftCard/submitTip.

Square wire parity (mock vs real):
- processing_fee sign unified (negated at paymentFromSquare; mock agrees).
- SimulateSourceUsed (SOURCE_USED, 400) matches real CreateCard.
- GetCardsOnFile excludes disabled cards (matches ListCards).
- ForcePaymentStatus toggle + tests prove the charge path can't be status-blind.
- CreateCheckout rejects empty device_id (env fallback SQUARE_TERMINAL_DEVICE_ID);
  completed terminal checkout's payment resolvable by id.

Security:
- 2FA attempt-map data race fixed: lastAt is atomic.Int64 (nanos) — eviction
  scan reads race-free; concurrent verify+evict tests under -race.
- Backend refuses to start on weak/placeholder JWT_SECRET_KEY (<32 chars or
  known public placeholders) with openssl rand -hex 32 guidance.
- Dockerfile no longer COPYs .env (secrets injected via compose env_file).
- SabreDAV requires DAV_ADMIN_PASSWORD (no admin/admin default); compose
  fails at config time when missing.

Testing gaps closed (each verified to FAIL without its guard):
- refunded-dedup 409 (CreateBookingPayment), keyed sweep past-retention
  blind-fail, reconcile status-switch (CANCELED/FAILED/APPROVED/PENDING/unknown
  in both by-key and by-id paths), resolveChargeSource Square-failure branches,
  structured 500 / CARD_DECLINED / cancelled-context E2E (row stays pending),
  deriveBookingPaymentIdempotencyKey >45-char truncation, webhook
  findPaymentByDisputeID fallback, clawbackOneTillSale non-gift-card branch,
  dispute.evidence / terminal.checkout dispatch.

Infra:
- local-dev-2.sh fails loudly on port-5432 squatters / docker compose failures
  (previously died silently under ERR_EXIT with hidden output).
- Test harness defaults SQUARE_TERMINAL_DEVICE_ID; money_safety_fixes_test.go
  gained the missing build tag.

Verification: go test -tags test,dev -count=1 -parallel 8 ./... (20/20 ok),
-race clean on 2FA + payments money paths, go build ./... + -tags dev, go vet
clean, svelte-check 0 errors, env-docs gate OK (36 vars), docker compose
config valid.

popertots 67cf5b9a45 fix: review round 6 — P0 deposit charge, idempotency rotation, dev-safety guard, 2FA/webhook hardening 
Sixth fresh-eyes review pass (5 agents: goal, QA, code-quality, security,
context-mining). QA FAILED the deposit-required new-card flow; the P0 root
cause was backend + frontend, now fixed. All 20 packages green.

P0 money-safety:
- Deposit-required bookings now actually charge the deposit on new-card
  payment. Two-part fix: (1) CreateBookingHandler re-reads the
  trigger-maintained total_amount/total_duration_minutes from the DB after the
  booking_services insert (the INSERT..RETURNING row predates the recalc
  trigger, so TotalAmount serialized as 0 and DepositPaid computed TRUE on an
  unpaid booking — the frontend gate trusted deposit_paid:true, never charged,
  and confirmed the booking with zero payment rows); (2) BookingFlow.svelte
  gates the confirmation view on depositPaid and guards against re-creating a
  booking on retry. Regression test
  TestBookings_Create_DepositPaidFalseOnUnpaidBooking.

Payments (idempotency + money):
- deriveBookingPaymentIdempotencyKey: no-client-key fallback now advances a
  sequence for repeatable types (partial) and rotates past refunded completed
  rows, so refund-then-repay and equal-amount partials diverge onto distinct
  keys; an un-refunded completed row keeps its key (double-charge protection
  holds). Dedup hits on refunded rows now 409, never stale success.
- chargeFailureStatus default is 503 (ambiguous), never 402; table test.
- Flaky TestBookingPayment_FullPayment_SplitsIntoDepositAndBalance fixed
  (ORDER BY payment_type).
- resolveChargeSource: orphaned card-on-file disabled via DeleteCardOnFile
  when SaveCardForUser fails (best-effort, redacted log); retry path preserved.

Square client:
- Dev builds HARD-FAIL (panic) on SQUARE_ENVIRONMENT=production without
  SQUARE_ALLOW_REAL_API=1; sandbox routes with a loud banner.
- Mock fault-injection FailAfterCommit (commit-then-5xx) exercises the exact
  lost-response same-key retry; SimulateCardTokenUsed; 45-char idempotency-key
  cap parity; SquareEnvironment/SquareLocationID shared env helpers used by
  the sweep (env contract no longer comment-only).
- listRefunds truncation now errors (money-sensitive reconcile retries
  instead of over-refunding); getCardsOnFile truncation loudly logged.

Webhooks + 2FA:
- square-environment header checked fail-closed (403) when configured env is
  production/sandbox; dispatch DB work bounded by 30s timeout contexts.
- 2FA codes HMAC-SHA256 pepper'd (TWO_FACTOR_PEPPER) with legacy-hash
  migration + upgrade-on-verify; disable-flow mint cooldown (1/min, 429) caps
  the brute-force loop; in-lockout records never LRU-evicted.

Repo hygiene:
- env-docs CI gate green again (FRONTEND_ORIGIN + SQUARE_ALLOW_REAL_API +
  TWO_FACTOR_PEPPER documented; Vite DEV built-in allowlisted).
- Dead square_deposits schema dropped; obsidian/README/legal-page drift fixed
  (consumeradvice.scot signposting, CORS allowlist, p11 R3/P13, T1).
- 2FA disable residual documented; P6 email/SMS delivery and P12 sandbox
  smoke test remain the pre-go-live gates.

Verification: go test -tags test,dev -count=1 -parallel 8 ./... (20/20 ok),
go build ./... + -tags dev, go vet clean, svelte-check 0 errors, env-docs
gate OK, live deposit-required flow re-verified end-to-end (deposit £11
charged, square_payment_id recorded).

popertots e9b0f0f2a7 fix: review-loop hardening — identical-body replay, 2FA gates, webhook at-least-once, GDPR scrub 
Follow-up to the comprehensive payment-system review. Fixes the issues the
review found in the initial integration, plus the rough edges it introduced.

Money-safety:
- Replay-by-key now replays the FULL original request verbatim from a stored
  square_request_snapshot, so a retained idempotency key returns the original
  payment instead of IDEMPOTENCY_KEY_REUSED (previously the row sat pending
  forever). IDEMPOTENCY_KEY_REUSED remains ambiguous (never proof of no charge).
- Dev mock mirrors real Square for unknown-key replays: ccof: saved-card
  sources are charged and rescued; spent cnon: nonces surface
  ErrReplayKeyNotRetained. (Fixes dev/prod parity divergence.)
- Webhook dedup row committed AFTER dispatch (at-least-once); FAILED till sales
  claw back gift-card funding; event-type strings match Square's real catalog.
- Expired-gift-card cancellation refunds set creditFailed (never a phantom
  'completed' refund); cancellation refunds lock all payment rows ascending.
- Sweep never rescue-completes a gift-card purchase without delivering the card.
- Tip no-client-key fallback is a deterministic count-based key under the
  booking advisory lock (retry-safe, distinct tips don't collapse).
- M-cap subtracts completed refunds, clamped to [0, total].

2FA (PSD2 SCA stand-in) for online saved-card payments:
- Full feature: status/setup/verify/disable endpoints, gating helper wired into
  all 7 saved-card charge paths (incl. BuyGiftCard + admin saved-card), account
  admin-tab settings UI, frontend gating across all payment surfaces.
- Enforcement is FAIL-CLOSED: on unless REQUIRE_2FA=false or an explicit
  mock/dev SQUARE_ENVIRONMENT; startup warning when off in a non-dev env.
- Verify is brute-force hardened (5-attempt lockout, timing-safe compare);
  plaintext codes only logged when enforcement is off (dev).
- GDPR: anonymize_user also scrubs 2FA columns and staff notes.

Infra/docs:
- nginx: /api/ response cache removed (cross-user disclosure); port 80
  redirects to HTTPS (localhost/RFC1918 exempt, end-anchored regexes); HSTS;
  separate webhook rate-limit zone.
- Schema: users 2FA columns; payments/till_sales square_source_id +
  square_request_snapshot.
- Legal docs: gift-card cooling-off, international-transfers section, tips
  policy; Gap Backlog P3 webhooks marked done; stale counts/wording corrected.
- Flaky test race fixed (t.Parallel + global mock mutation); suite 26/26
  packages green, 2,142 tests, svelte-check clean.

popertots 8ff77bc39b Add tests for Square client hardening and GDPR deletion 
Covers DeleteCustomer (success + NOT_FOUND no-op), doJSON truncation (oversized bodies + rune-safe capBody), validCardID rejection without leaking the token, paymentFromSquare empty-card consistency, and mock-side customer-ID redaction in logs.
 2026-08-22 00:34:49 +01:00
popertots 12af3af3b3 Harden Square HTTP client and dev mock: status codes, token validation, deadline wire format 
Add StatusCode/Category/Field to squareAPIError and an IsNotFound helper so 400/401/404/429/5xx are distinguishable structurally instead of by substring. Validate cnon:/ccof: token prefixes in createPayment/createCardOnFile (PCI parity with the mock). Reject ccof charges without customer_id in the mock so dev parity catches the production bug. Emit Deadline as the RFC 3339 duration (PT5M) and correct the deprecated-comment.

popertots 54a5b1024e Implement full Square payment review fixes + frontend polish 
Implement every finding from the deep payment review (P0-P2, minors,
nitpicks), then close the post-implementation re-review items, then
align card-form typography and roll out the Square trust badge.

Backend - Square API alignment:
- tip_settings.allow_tipping nested under device_options (was top-level:
  terminal tips were silently lost in prod)
- CreateCardOnFile now accepts customerID and sends card.customer_id;
  saved-card (ccof:) charges forward square_customer_id as CustomerID
- New SquareClient methods GetPayment, CreateCustomer, CancelCheckout
- SCA verification_token accepted + forwarded in all charge paths
- ExpMonth/ExpYear -> *int; URL-path id validation; CancelCheckout
  NOT_FOUND-only no-op (dropped unverified NOOP); exported ErrorCode/
  ErrorDetail helpers; mock rejects raw PANs, RList locks, redacts
  emails, ForceRefundPending hook

Backend - money safety:
- sweepManualPendingSquareRefunds reconciles rows WITH square_refund_id
  instead of stranding them forever
- SweepStalePendingPayments reconciles at Square before failing (tri-state:
  leave pending on transport error, rescue completed, fail definitively)
- GetCheckoutStatus cancellation-recheck; terminal CANCELED resolution;
  SweepStaleTerminalCheckouts covers terminal_checkouts table
- till gift-card clawback on definitive failure incl. retry path +
  INSUFFICIENT_FUNDS/ADDRESS_VERIFICATION_FAILURE/TRANSACTION_LIMIT
- cross-user saved-card collision fixed (UNIQUE(user_id,square_card_id))
- customer provisioning (lazy, save-only); one-off/guest mint no customer
- discount preview/apply unified in discounts.go (global-milestone visible
  in preview, N+1 eliminated, redemption counter preserved on failures)
- webhook event_id dedup; refund loop dedup; stale comment fixes
- test-isolation t.Cleanup on committed sweep tests

Frontend:
- SCA tokenizeWithVerification across all charge flows (amount as
  major-units decimal), 5-min token-expiry re-tokenize, verification_token
  in request bodies
- PaymentModal synchronous double-click + zero/negative-amount guards
- till online-card UI wired to /api/admin/till/sale
- policyPopover generalised; new /privacy-policy route; consent checkbox
  copy + Square privacy link
- Square card iframe styled to app typography (Inter 14px, oklch tokens);
  mock form md:text-sm parity
- 'Secure payment powered by Square' badge on all 8 card-payment flows

Schema/docs: terminal_checkouts + square_customer_id + per-user card
constraint in init-script.sql; README migrations; P14 plan + backlog +
Technical Manual updated.

Includes 39 modified/new test files; full backend suite (25 pkgs),
-race on payments+square, and frontend build are green.

popertots 7439fa86c1 Fix payment review round 3: saved-card idempotency, stale-pending sweep, webhook fail-closed 
R1/R4: saved_card branch in CreateTerminalPayment now mirrors CreateTipPayment
- advisory lock (crussell:payment:<bookingID>) serializes concurrent double-clicks
- deterministic key bookingID-sc-type-amount-cardID (<=45 chars) so a lost-response
  retry derives the same key and dedups instead of double-charging
- idempotency switch inside the lock: completed -> dedup, pending -> reuse with
  pence amount-guard, failed -> clean 409
- success response includes card_brand/card_last4 (frontend already reads them)

R2: add 'failed' case to all four retry switches (tip, booking, gift card, till)
- a swept/definitively-rejected record returns 409 instead of 500-ing on the
  idempotency_key UNIQUE constraint

R3: extend SweepStalePendingPayments to till_sales card rows
- sweeps pending till_sales (online_square/in_person_card) past Square's ~24h
  key retention, closing the double-charge window for till sales
- swept rows logged with the same CRITICAL manual-reconciliation marker as the
  refund sweep

Webhook fail-closed: reject 503 when SQUARE_WEBHOOK_SIGNATURE_KEY unset, 403 on
bad signature (was: skip verification in dev)

Refund status resolution: refunds now resolve by Square status
(COMPLETED/PENDING/FAILED/REJECTED) instead of assuming completed; real error
codes (REFUND_AMOUNT_INVALID, PAYMENT_NOT_REFUNDABLE, REFUND_ALREADY_PENDING)
added to the definitive/processed classification

HTTP client: CreateCard key truncated to <=45 chars, device_options always sent
(env SQUARE_TERMINAL_DEVICE_ID fallback), processing_fee reads amount_money,
ListCards cursor loop, refund keys hashed to <=45 chars

Other fixes: payment/till/gift-card advisory-lock + FOR UPDATE asymmetries,
GetPaymentByID NULL scans, loyalty redemption lock, card upsert on conflict,
mock ccof: prefix parity, IsValidSquareCheckoutID for real Square IDs,
isAdminRequest defense-in-depth on all 6 admin payment handlers, webhook
signature docs, M8/L5 debug markers removed

Docs: README/FC/TM/Overview updated (22 jobs, 20 CRITICAL sites, 23-section
GDPR export, sweep jobs, webhook fail-closed); P11 plan marks remaining items
(sandbox smoke test, M-8 customer_id, saved-card key dedup trade-off) as
deferred with rationale; gap backlog pruned of completed items
 2026-08-22 00:34:49 +01:00
popertots 16240d67e3 Fix Square card linkage: reference_id instead of customer_id (no Square customer provisioning) 
The app does not provision Square customers, so sending the local user ID as
customer_id in Create Card was rejected with CUSTOMER_NOT_FOUND, and filtering
List Cards by it returned nothing. reference_id is Square's free-form client
reference — max 128 chars, no uniqueness constraint — and is echoed in both
Create and List responses.

- Create Card payload: reference_id = local user ID (customer_id absent)
- List Cards: native ?reference_id=<userID> filter (no limit/customer_id,
  no client-side filter, no cursor handling needed)
- Mock parity: CreateCardOnFile stores ReferenceID; GetCardsOnFile unchanged
- Regression guards: TestCreateCardOnFileHTTP_IdempotencyKey asserts
  reference_id=user_1 and customer_id ABSENT; new
  TestGetCardsOnFileHTTP_ReferenceIDFilter asserts the query shape
 2026-08-22 00:34:49 +01:00
popertots 53ca89603d Fix payment review round: till integrity, HTTP client tests, concurrency tests, card-selection consolidation 
Addresses the payment review (all 10 blocking + 2 minor findings):

Till money-integrity (CreateTillSale):
- Add pg_advisory_lock on the idempotency key (concurrent same-key double-funding race)
- Guard amount on pending-reuse retry (mirrors tip/gift-card guards)
- Explicitly complete the row for cash/on_the_house pending-reuse
- Reject method-switch on a live card-machine checkout (double-charge guard)
- 3 regression tests (amount-mismatch, cash-completes-row, method-switch)

BookingFlow:
- Fetch saved cards at the deposit step (was dead code)
- Charge the server-computed deposit_amount, not the client estimate

HTTP client tests (was untested): doJSON error parsing, refund sentinel
classification, payment/refund/card wire shapes, checkout polling states,
list-refunds pagination + 20-page guard, sha256 card idempotency key

Concurrency regression tests: real two-goroutine races for BuyGiftCard,
tip, and booking-payment locks asserting exactly-one record each

Frontend:
- Fix CRIT-1: zero-saved-card users blocked (all flows now handle it)
- Consolidate tip/deposit/Buy-Gift-Card card UI onto CardSelection
- Explicit save-card consent checkbox (was silent/inconsistent)
- Fix stale saved-card field names in BookingFlow (last4 -> last_4)
- Unique instance ids (crypto.randomUUID) in CardSelection/SquareCardInput
- UserPaymentModal: keep card form mounted on error + Try Again button

Health/docs: /api/health reports square state (mock/ok, was not_implemented),
close P1 backlog, correct stale webhook and env-var claims
 2026-08-22 00:34:49 +01:00
popertots 4f5dd5c426 Fix review findings: BuyGiftCard concurrency lock, amount guards, NULL scan, mock dedup, docs 
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.
 2026-08-22 00:34:49 +01:00
popertots 28f0ddb328 Fix tip amount-change false dedup, wire BuyerEmail everywhere, clear ESLint errors 
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.
