#### 2.3 Outbound Webhook Subscriptions ⚠️ PARTIAL
#### 2.3 Outbound Webhook Subscriptions ✅ BUILT
> **Current state:** `lib/webhooks.ts` still fire-and-forget for 3 events. No `modules/webhooks/` directory exists — subscription model with HMAC signing + retry has NOT been built.
> **Implementation:** `modules/webhooks/` (4 source files) — subscription CRUD, HMAC-SHA256 signing, exponential backoff retry (3 attempts), auto-disable after 10 failures, secret rotation, delivery log. Registered in `cosmos-init.ts` (`webhook_subscriptions`, `webhook_deliveries`). Legacy `lib/webhooks.ts` still exists for backward compat.
**Why:** Current `webhooks.ts` is fire-and-forget to env-var URLs with no retry, no signing, no subscriber management. External integrations (Zapier, Slack, custom) need a proper webhook subscription system.

#### 2.8 Database Migration & Schema Evolution Tracker ❌ NOT STARTED
#### 2.8 Database Migration & Schema Evolution Tracker ✅ BUILT
> **Status:** No `migrations/` directory exists. Schema changes are still applied ad-hoc.
> **Implementation:** `src/migrations/` (3 source files: types.ts, registry.ts, runner.ts) — idempotent migration runner on startup, Cosmos `migrations` container for tracking, best-effort (failures dont block startup). Admin can query via `listMigrations()`.
**Why:** Cosmos DB is schemaless, but breaking changes still happen: new required fields, partition key changes, index policy updates, container renames. Without tracking, deployments are error-prone and rollbacks are impossible.

#### 2.19 OpenAPI / Auto-Generated API Docs ⚠️ PARTIAL
#### 2.19 OpenAPI / Auto-Generated API Docs ✅ BUILT
**Why:** Platform-service already passes `swagger` config to `createServiceApp()`, but Zod schemas aren't fully wired to route definitions. The admin `/docs` page is a markdown doc browser (not API docs). Auto-generated API docs from Zod schemas would be nearly free.
