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. |

Sweep lost-response charges by idempotency-key replay (22h cutoff, rescue/fail/WARN)
The stale-pending sweep now runs two passes. Pass 1 (22h cutoff — deliberately 2h earlier than the 24h legacy cutoff) targets pending rows with a STORED idempotency key but NO square_payment_id: the lost-response case, where the charge may have completed at Square with the response never received. Each row is reconciled at Square by replaying the key (ReplayPaymentByKey): a COMPLETED charge is rescued to 'completed' with the real square_payment_id written back, a charge Square proves never happened is failed (till-sale gift-card clawback included), an ambiguous answer leaves the row pending for the next run. The earlier cutoff keeps the replay inside Square's ~24h key-retention window; replaying at exactly 24h risks an expired key misreading as 'never charged'. Pass 2 (legacy 24h cutoff) reconciles rows WITH a square_payment_id by payment id; rows with neither payment id nor stored key (no reconcile possible) are failed with a WARN that the charge outcome is unknown. Late retries on all swept rows are rejected (409), preventing a second Square charge. |

Fix till-sale money safety: sweep gift-card clawback, orphaned-checkout cancel, cash-retry reconciliation
HIGH-1: a till sale whose card-machine checkout is provably dead, or whose Square reconcile proves the charge never landed, now claws back the funded gift card atomically with the failed mark (claim-first gating UPDATE serializes against the admin retry; blind-fail and ambiguous/lost-response rows never claw back, and a bare CANCEL_REQUESTED is not treated as proof of non-completion). HIGH-2: a card-machine checkout created at Square but not committed is cancelled on any pre-commit failure. HIGH-3: a cash/on_the_house retry of a pending card sale is reconciled at Square first (COMPLETED rescues + refuses cash; NOT_FOUND/FAILED/CANCELED allows cash; lost-response forces the card-method retry; ambiguous rejects). GetTillCheckoutStatus no longer resurrects a swept-failed sale, and the cash-completion UPDATE checks RowsAffected so the admin is never told to take cash against an already-resolved sale. 23 new tests covering the clawback matrix, the reconcile-or-reject matrix, cancel-on-error, and a till concurrency test. |

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. |
