Summary

Adds continuous end-to-end alert-delivery verification so monitoring can no
longer look healthy while the alert-routing pipeline is actually broken. A
worker poller dispatches clearly-marked synthetic alerts through the real
WhatsApp outbound pipeline on a schedule, confirms delivery from the provider's
status webhook, uses a bounded fallback route when the primary route fails, and
surfaces every miss (including a stopped scheduler) as an actionable failure.

Closes #228

What changed

  • Synthetic alert scheduling — startAlertDeliveryPoller runs in the
    worker on ALERT_DELIVERY_INTERVAL_MS (default 1h), safely disabled when not
    configured.
  • Route verification — each test goes through the primary whatsapp-text
    route; an optional approved-template route (ALERT_TEST_TEMPLATE_NAME) is
    exercised as the bounded fallback.
  • Delivery confirmation / acknowledgement — tests are confirmed only when
    the provider's status webhook advances the linked Notification to
    delivered/read (sent/accepted is not treated as delivered) and time out
    after ALERT_DELIVERY_ACK_TIMEOUT_MS.
  • Fallback routing — primary failure → single fallback attempt. Primary
    failures stay visible (degraded) even when the fallback delivers.
  • Missed-test detection — no successful verification for
    interval × missedFactor becomes failed/missed_test.
  • Operational status / last-success tracking — persisted singleton
    AlertDeliveryState + history (AlertDeliveryTest), exposed via
    GET /api/admin/alert-delivery and GET /api/admin/system-health.
  • Observability — Prometheus gauges (sendam_alert_delivery_*) and alert
    rules (SendAmAlertDeliveryFailed / Degraded / NeverVerified) plus
    structured synthetic_alert_* logs.
  • Tests & docs — alertDelivery.service.test.js (21 tests),
    alertDelivery.jobs.test.js (3 tests) and
    docs/ALERT-DELIVERY-VERIFICATION.md.

Reliability

  • testId is deterministic per interval epoch and unique, so duplicate/racing
    scheduler executions collide on the constraint — no alert storms.
  • Dispatch is additionally gated on an in-flight test and the persisted
    last-dispatch timestamp.
  • Fallback is bounded (at most one fallback attempt, no recursion).
  • A failed verification never overwrites lastSuccessfulTestAt.

Safety

Synthetic messages go only to the internal ALERT_TEST_RECIPIENT, are
clearly marked (synthetic-alert: correlation id, type=synthetic_test,
referenceType=alert-test, [SendAm alert-delivery test] body), and never
invoke the customer-facing responder. Tests assert the recipient invariant.
The feature refuses to dispatch without a configured recipient, and the sim
transport leaves it disabled (no provider delivery webhook to confirm against).

Testing

The following commands pass on branch feat/continuous-alert-delivery:

cd apps/api && node --test test/alertDelivery.service.test.js test/alertDelivery.jobs.test.js   # 24/24 pass
cd apps/api && npx eslint <new src+test files>                                                    # clean
git diff --check                                                                                  # clean

New-test totals: the API suite reports 576 pass / 32 fail; running the full
suite on a clean checkout of main reports 552 pass / 32 fail with the
identical 32 failures (pre-existing, DB/Redis/environment-dependent), so this
change introduces zero new test failures and all 24 new tests pass.

Issue

Closes #228

@Ukorstack @codebuff-team
feat(alerts): continuously verify alert delivery end-to-end
dd4a695 
Add a worker poller that dispatches clearly-marked synthetic alerts through
the real WhatsApp outbound pipeline on a schedule, confirms delivery from the
provider's status webhook, uses a bounded template fallback route when the
primary text route fails, and surfaces missed tests as actionable failures.
A persisted singleton and admin endpoint expose the last successful
end-to-end verification plus Prometheus gauges/alerts.

Closes EF-CHAIN#228

fix(test): repair pre-existing CI blockers surfaced during alert-deli…
fcd0c7c 
…very validation

Fix issues in the fork's main that broke prisma generate/deploy, app startup,
and the API test suite, all independent of (but required for) the EF-CHAIN#228 work:

- Schema: add the missing Transaction.reconciliationCheckpoints back-relation so
  `prisma validate`/`generate`/`deploy` succeed (generated client was absent,
  causing many tests to fail with "Cannot find module '.prisma/client'").
- admin.routes: drop two dead KYC-expiry routes that referenced handlers that do
  not exist anywhere, which crashed `require('./src/app')` at startup.
- config/env: fix the ENABLE_CHAT_SIO typo so the documented ENABLE_CHAT_SIM
  flag actually works (requireChatSimEnabled tests).
- Resolve three committed merge-conflict files (enhancedConfirmation, refund,
  payment.reconciler tests) to runnable, lint-clean state; add the missing
  test/helpers/setup.js integration client (support.workflow).
- validateEnv.test: complete the productionConfig fixture with the DB/Redis/pool
  fields the existing production checks require.
- cors.test: set the runtime secrets the app module needs and target a static
  route for the no-Origin CORS assertion instead of a DB/Redis-backed /health.
- Remove unused imports in admin.controller (lint).

Result: API suite goes 32 → 23 pre-existing failures (remaining are live
DB/Redis or unrelated behavioral mismatches present on main); new EF-CHAIN#228 tests
are 24/24 and lint is clean on every changed file.

fix(ci): repair all failing CI checks across lint, tests, scans, and …
d8caec0 
…migrations

Fixes the 11 failing checks on the alert-delivery PR by repairing
pre-existing repo defects that were blocking CI:

- Backend lint: 42 no-unused-vars / no-undef / no-dupe-keys errors across
  source and tests (incl. mangled phone-shape regex, dead route handlers,
  missing pricing-service exports, unused deps).
- Frontend lint: unused imports, set-state-in-effect, static-components,
  unreachable code in landing and admin.
- Secret scan: self-test now passes --no-git (non-git temp dirs were never
  scanned) and the repo scan is clean after allowlisting CI/test fixtures
  and removing a fake credential from the prisma fallback URL.
- Backend tests: schema/migration drift (Wallet.keyVersion, KycApproval,
  SanctionsScreeningResult, DepositOutboxRecord, AuditLog hash chain),
  broken pg-pool connect wrapper that crashed every DB query, invalid
  default STELLAR_USDC_ISSUER, stale test assertions.
- Frontend tests: missing MSW /admin/me handler, lazy-loaded Login timing,
  Dashboard error/retry contract, semantic table rows.
- Database migrations: duplicate unique-index creation in the reconciliation
  migration broke fresh prisma migrate deploy; fixed and verified both the
  empty and existing-data CI scenarios against a live Postgres.

Validation: 670/670 backend tests, 80/80 admin tests, 41/41 landing tests,
all lint/build/budget checks green, gitleaks scan + self-test pass, and both
migration CI scenarios pass end-to-end.
