- TWO_FACTOR_ALLOW_LOG_DELIVERY production opt-in REMOVED: plaintext codes are written to the stdout log ([2FA]/[VERIFY]) only in dev/test builds as a local DEV ONLY feature while email/SMS delivery (P6) is implemented. Production builds have no delivery channel and code issuance fails closed (503) under any configuration — no silent log-based code leak
- verification/2FA codes hashed at rest (HMAC-SHA256 via TWO_FACTOR_PEPPER, CHAR(64)); [VERIFY] dev log relay; per-user brute-force budget; password_reset purpose clears lockout for self-service recovery; dummy-bcrypt on login no-user path kills timing oracle
- sabredav weak-password list + entropy gate; .env.example ships fail-closed DAV_ADMIN_PASSWORD
- delete-account re-auth (current_password + fresh 2FA code when enforced)
- prod-tag suite (run-prod-tag-tests.sh) compiles and runs the production 2FA issuance gate: production ALWAYS reports no delivery channel and refuses issuance after the pepper check
- startup_checks_test SNAPSHOT_ENC_KEY values built at runtime so gitleaks sees no secret-shaped literals
- env-docs parity updated (flag removed, 38 vars)
F5.5 brute-force hardening:
- internal/twofa.Check consume is now a conditional UPDATE (WHERE id AND
two_factor_pending_code_hash) reporting rows affected: two concurrent
verifications of the same code on different instances both match the digest,
but only the first conditional UPDATE can affect a row — the loser sees 0
rows and fails MissingOrExpired, so one code authorizes exactly ONE operation
across instances (the per-user mutex only serialized within one process).
- /login lockout is now indistinguishable from a wrong password: a locked
account returns the same uniform 401 'invalid credentials' and burns the same
constant-time bcrypt compare (via the shared semaphore), removing the
account-existence oracle and lockout-probing signal of the old 429.
- Lockout tiers escalate 15m (5+) / 30m (7+) / 60m (10+): an attacker who keeps
guessing past each unlock makes the lock LONGER, raising the repeat-DoS
effort while the response stays uniform.
Round 2 Loop A fresh money/security/dup-mod review. 23 findings fixed:
MONEY:
- CRITICAL: B1 duplicate auto-refund gains an attempt cap (b1_attempts col, cap 3) —
a rejected auto-refund no longer re-replays the expired key every sweep run
(which minted a stacking unauthorized charge each time); FAILED-webhook
demotion respects the cap; never re-replay a key whose B1 refund failed
- HIGH: A6 deposit_covered_by_discount skip path now APPLIES the eligible
campaign discount rows immediately (capped) instead of skipping with no
discount recorded — no more promised-discount-not-recorded overcharge
- MEDIUM: 2FA code burned by the SAVE gate is re-issued on failed
new-card+save_card charges (re-issue guard now covers req.SaveCard)
- LOW: GetBookingPaymentSummary excludes tip rows from paidAmount (remaining
now matches the authoritative tip-excluded balance)
SECURITY:
- MEDIUM: unacknowledged CRITICAL admin-notification flood capped (global cap
on critical_payment_log + refresh_token_reuse rows)
- MEDIUM: 2FA reissue no longer bypasses the mint cooldown (Check no longer
clears LastMintAt on gate-verify; cleared on terminal charge success)
- MEDIUM: twofa.StateFor map-saturation returns a shared permanently-locked
state instead of a fresh 5-guess budget per request
- MEDIUM: ProgressiveRateLimit rejects 429 past maxProgressiveSleepDelayMs
instead of sleeping unboundedly; login bcrypt concurrency semaphore added
- LOW: loginInProgress 409->429; webhook key-set/URL-unset startup check;
email-verification per-user attempt counter
DUP/MOD:
- formatCurrency single source (frontend format.ts, 7 files consolidated);
SquareRefundStatusToLocal single source (errors.go, all sites); admin
audit-log helper dedup; SCA retry model unified (proactive on all 6
surfaces); buyDailyTotal/daily-cap mirror via backend; lock TTL from
backend; generateUUID at all card-form sites; magic numbers named
(defaultPostgresHost, epsilon, fee constants); admin CASH + gift-card
terminal charges now audited; DAV_SKIP_INIT documented in manuals
Verified: 26/26 dev + 24/24 prod (GO_TESTING=1, the CI condition), both vet
tags, frontend tests+build, env-docs 42/42.
Full-scope Loop A restart review (18 findings across money/security/dup-mod):
MONEY:
- HIGH: amount_paid/amount_due CTEs now exclude payment_type='tip' (bookings.go x6, today.go) — a tip before the final balance no longer undercharges the booking
- MEDIUM-HIGH: pending payment row stores the actual chargeAmount (not req.Amount) so the sweep replay amount-match rescues deposit-with-discount rows instead of auto-refunding them; refundSweepDuplicateCharge refunds the replayed payment's actual amount
- MEDIUM: A6 deposit clamp-up now caps at the discounted obligation (remainingPence - eligibleDiscountPence) — no more silent overcharge when a campaign discount >= deposit
- MEDIUM: B13 campaign-loss balance credits are clawed back on cancellation (clawbackB13CampaignCredit in ProcessCancellationRefundTx)
- LOW: replayLegitimateRetryWindow extended 22h->24h so a legitimate same-key retry in the retry-eligible window is rescued, not auto-refunded
SECURITY:
- 2FA single-use strengthened (consume-at-gate for fresh charges, re-issue on failure)
- Admin 2FA mint now writes admin_audit_log + logs code reuse
- Account deletion requires current password (and 2FA when enforced) — stolen token can no longer destroy the account
- Multi-tab refresh-token replay deduped via cross-tab lock (no false family-kill alerts)
- family-alive cache invalidated on password change / GDPR erasure
- Login lockout keyed per user+IP with a capped ceiling
FRONTEND/DUP-MOD:
- OverflowTipConfirm shared component (UserPaymentModal + BookingFlow); overflow computation aligned (deposit-discount-aware)
- PaymentModal admin 2FA gate now method-conditioned (no over-reveal on cash/giftcard)
- requestTwoFactorCode shared helper (requestNewTwoFactorCode + adminRequestNewTwoFactorCode)
- BookingFlow deposit display aligned to the discounted amount; formatCurrency used consistently
26/26 backend packages; 80/80 frontend tests + build; env-docs 41/41.
Loop B restart (money/security/dup-mod adversarial) fixes:
- CRITICAL: CreateTerminalPayment rejects payment_type='tip' (mirrors CreateBookingPayment) — a tip-typed admin charge no longer records the FULL amount as a tip and double-collects (all is-paid computations exclude tip rows)
- HIGH: tip refunds can no longer re-open booking capacity — refunded_total subqueries filter payment_type <> 'tip' (service.go) and RefundPayment rejects tip rows
- MEDIUM: loyalty-stamp farming closed — stamp award once-per-booking via loyalty_stamp_awarded_at column (init-script.sql) + existing same-day guard
- MEDIUM: CreateTipPayment/CreateBookingPayment 2FA gates moved AFTER the idempotency completed-dedup (code consumed only on new money paths; terminal path already correct) — lost-response retries return the completed payment instead of 400
- MEDIUM: replayRescueLowerBoundSkew widened to 5m (DB-clock-skew stranded originals now rescued)
- MEDIUM-1: verifyFamilyAlive DB amplification reduced via 30s bounded family-alive cache; admin route group rate-limited
- MEDIUM-3: admin saved-card charges now write admin_audit_log (handlers.go helper + till); [2FA] log line decoupled from user identity
- LOW-1: logout scoped to the presented token's family (no cross-session kill)
- LOW-2: refresh-reuse grace widened for same-IP replays
- LOW-4: squareEnvironmentMismatch enforced for empty env
- LOW-5: uuid.ts hard-fails on Math.random fallback (crypto.randomUUID)
- Cash/giftcard tip-enabled overflow mirrors the card-terminal carve
26/26 backend packages; 72/72 frontend tests + build; env-docs 41/41.
Restart of Loop A (fresh review -> fix -> verify) findings from commit 5e967fa:
- B1: sweep auto-refund treats Square PENDING refunds as NON-terminal (row stays pending, no gift-card clawback, refunds row inserted for payments AND till_sales, re-polls the deterministic sweepdup- key); Square-less pre-pass exempts square_refund_id IS NOT NULL rows
- M4: terminal tip carve accounts for pending campaign discounts (headroom = total - pending - paid) so explicit tips aren't absorbed as service revenue; no-tip case stays a single record
- max_redemptions TOCTOU closed with atomic conditional UPDATE ... RETURNING; exhausted-at-apply surfaces campaign_fully_redeemed
- 2FA: verification code is single-use on the saved-card gate (VerifyForUser consume=true, interactive flows unaffected); new POST /api/user/2fa/code mints a fresh code for enabled users (RequireAuth + RequireNonGuest + mint cooldown + per-user limiter)
- Refresh tokens: family_id + used_at columns; reuse of an already-rotated token revokes the ENTIRE family and inserts a refresh_token_reuse admin alert; rotation mints descendants in the same family
- Frontend: 2FA code input + Request-a-new-code on all saved-card surfaces; admin modal keys code input to customer 2FA + 403 self-heal; tip-display note for pending discounts; 76 frontend tests
- Verified: all 26 backend packages pass, frontend build+tests green, env-docs 41/41
New test files cover previously untested paths across DAV, validators,
S3, Square, mw, bookings, user, and payments packages.
Includes mock fix: HoldCheckouts flag on MockClient allows tests to
pause auto-complete goroutine for testing PENDING checkout states.
