fix: round-2 loop-B adversarial (503c326 baseline) — B1 webhook race, APPROVED refund semantics, notification cap single-source, 2FA cooldown/StateFor hardening, register bcrypt semaphore
Round 2 Loop B red-team (money/security/dup-mod adversarial) findings on the full payments overhaul:
MONEY:
- HIGH: webhook COMPLETED promotion now resolves the B1 parent row (mirrors the re-poll resolveB1ParentFailed + till-sale clawback) — the sweep no longer re-replays an expired key into stacked unauthorized charges
- HIGH: A6 deposit-with-discount clamp — chargeAmount capped to max(0, remaining-discount) for ALL discount cases; overflow guard compares against the discounted remaining
- MED-HIGH: APPROVED refunds treated as NON-terminal at the webhook (event-driven, may still fail); payments call sites aligned; FAILED can now demote an APPROVED-then-failed row
- MED: B1 refund transport-error fails the row + CRITICAL immediately (no 3-charge stacking)
- MED: till_sales capped-fail surfaces the outstanding funding (gift_card_transactions trace) for manual reversal
- MED: guest-bookings cash/gift-card terminal charges now audited (NULL target); audit reordered post-commit; cancellation refunds audited
- MED: A6 no-discount skip-path returns campaign_fully_redeemed 400 (no success-shaped no-op); skip-path writes a marker row for idempotency
SECURITY:
- HIGH: notification cap centralized in adminnotify (MaxUnacknowledgedCriticalLogs) + applied at ALL insert sites (webhooks x2, jwt refresh_token_reuse, account erasure, sweep, twofa) with suppressed-insert logging; per-issue bucket for reissue alerts
- MED-HIGH: twofa.StateFor saturated state made IMMUTABLE (LastMintAt writes are no-ops; no cross-user throttling); eviction never drops in-window count>0 records
- MED: /register now uses the shared bcrypt semaphore (authBcryptSlots, 20) — botnet CPU burn bounded
- MED: NAT collateral reduced (429-reject only at top progressive tier; lower tiers sleep)
- MED: ClearMintCooldownForUser exposed for fresh-charge success; reissue cooldown-skip raises a capped alert
- LOW: audit coverage gaps (reschedule fee forgiveness, gift-card transfer, clawback) closed
DUP/MOD:
- Frontend deposit-percent literals -> POLICY constants (10 sites); LOYALTY_DISCOUNT_RATE single-sourced; generateUUID adopted; admin PaymentModal overflow-tip confirm path added; £500 gift-card cap named
Verified: 26/26 dev + 24/24 prod (CI condition), both vet tags, frontend tests+build, env-docs 42/42.
