PR2 of Phase B. Wires the alert framework end-to-end:
- alert-rules.ts: 10 rule evaluators implemented as pure async fns over
the existing schema. reservation.no_agreement, interest.stale,
document.signer_overdue, berth.under_offer_stalled, expense.duplicate,
expense.unscanned, interest.high_value_silent, eoi.unsigned_long,
audit.suspicious_login fire against real conditions.
document.expiring_soon stays inert until the documents schema gets an
expires_at column. audit.suspicious_login also stays inert until the
auth layer logs 'login.failed' rows (TODO noted in the rule body).
- alert-engine.ts: runAlertEngine() walks every port × every rule and
calls reconcileAlertsForPort. Errors per (port, rule) are collected
in the summary, not thrown — one bad evaluator can't stop the sweep.
- alerts.service.ts: reconcileAlertsForPort now emits 'alert:created'
socket events on insert and 'alert:resolved' on auto-resolve;
dismissAlert emits 'alert:dismissed'. All scoped to port:{portId}
rooms.
- socket/events.ts: adds the three Server→Client alert event types.
- queue/scheduler.ts: registers 'alerts-evaluate' on the maintenance
queue with cron */5 * * * * (every 5 min, per spec risk register).
- queue/workers/maintenance.ts: dispatches 'alerts-evaluate' to
runAlertEngine; logs sweep summary.
Tests:
- tests/integration/alerts-engine.test.ts (6 cases): seeds reservation
→ fires, runs twice → no dupe, adds agreement → auto-resolves; seeds
stale interest → fires; hot lead silent → critical; engine summary
shape on no-data port. Socket emit module is vi.mocked.
Vitest 681/681 (was 675; +6). tsc clean. Lint clean.
