Settlement alarm (settle-pass THROW pages high; morning zero-settle alarm keyed off the Postgres ledger settle results, once per ET date, never on an empty yesterday), per-sport 3-consecutive-slot failure pager (pure opsWatch.createFailureTracker, pages once per losing streak), odds-api >=80% quota alert (once per day, Redis-deduped), systemHealth (statfs + os mem, disk>85 / mem>90 pages), daily 9 AM ET pulse (ONE notification: ledger rows yesterday via ledgerService.countRowsForDate, settles 24h, quota, disk/mem, desk line), docs/OPS-RUNBOOK.md (Uptime Kuma monitors, Coolify deploy-failure -> ntfy, phone subscription). All copy VOICE v1.1 — deadpan, numbers, no exclamation points (tests lint for it). 2398 -> 2437 tests. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
