- 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.

Defense-in-depth: referral codes are generated as hex (lowercase only) by the DB. The frontend already lowercases on input, but direct API calls with uppercase would fail the DB lookup. Normalize to lowercase on the backend to prevent capslock situations.
