VITE_SQUARE_ENVIRONMENT=mock renders a plain HTML card form (MockCardForm)
instead of the Square Web Payments SDK iframe, minting the same cnon: tokens
the backend dev mock accepts — all 8 payment flows run end-to-end locally with
zero credentials.
- isSquareMock() gated on import.meta.env.DEV: structurally impossible in a
production build even if the env var is mis-set
- MockCardForm: Luhn/brand/expiry/CVC validation, Amex 15-digit + 4-digit CVC,
error states, disabled propagation — mirrors the real form's onReady contract
so CardSelection.isCardValid and submit guards behave identically
- tokenize() maps typed card -> deterministic cnon: token matching backend
detectCardInfo (4242->test-card, 4111->visa, 5555->mastercard, 3782->amex)
- lazy-loaded via dynamic import: mock code ships in its own chunk, referenced
only from the mock branch, never statically imported into the main bundle
- docs: .env.example (mock pairing with SQUARE_ENVIRONMENT=mock), P11 plan
(mock opt-in + canonical-last4 caveat), Feature Catalog (2.1, 2.5)
- prettier formatting fixes in 10 unrelated files (line wrapping only)
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
The customer_id-required question (Card schema says Required, spec says
nullable) can only be resolved by a real sandbox Create Card call. The smoke
test remains the gate before any production flip: new-card tokenization ->
payment -> saved card -> refund -> reconcile against a real endpoint.
Re-enable new-card entry across all 8 flows via Square Web Payments SDK
cnon: nonces (backend was already P11-ready):
- Add square.ts SDK loader (env-gated on VITE_SQUARE_APPLICATION_ID/LOCATION_ID,
sandbox vs prod URL auto-derived from app-ID prefix) + SquareCardInput.svelte
(tokenize() via bind:this, onReady state, CardEntryUnavailable fallback)
- CardSelection.svelte: replace newCardDisabled gate with new-card toggle +
SquareCardInput; expose tokenize() for parent flows
- Wire new-card mode into tip x3, booking payment (UserPaymentModal), deposit
(BookingFlow incl. guest), Buy a Gift Card + Add a Card (account), and admin
till online_square (GiftCardsManagement create/topup)
- Retry-safe: each flow caches the one-shot nonce and reuses it on retry so the
backend idempotency key dedups instead of re-tokenizing
- Docs: README, Gap Backlog P11, Feature Catalog, Technical Manual, P11 plan
The P11 plan was written when the frontend sent raw PANs and the backend
had CreateCardOnFileRaw blocked. Four rounds of payment-safety work
changed the reality: the backend is fully P11-ready (CreateCardOnFileRaw
deleted; all card-creation paths accept cnon:/ccof: tokens via
CreateCardOnFile) and new-card entry is gated behind CardEntryUnavailable.
- Rewrite plans/p11-square-web-payments-sdk.md: accurate current state
(8 gated flows), backend-readiness section with verified line evidence,
Steps 4/5 marked done, revised to a frontend-only 2-3 day integration
(SquareCardInput replaces the deleted CardInput.svelte)
- README: online payments via saved cards; new-card entry gated until
nonces land; backend accepts tokens only (PCI-DSS parity)
- Gap Backlog P11: backend groundwork DONE, remaining work is
frontend-only re-enable of the 8 gated flows
- Feature Catalog 2.1/2.5 and Technical Manual: gated-not-dead-end;
Add Card posts card_token to CreatePaymentMethodFromToken
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)
