## Today's Plan

1. **FRE-4493** (Build API gateway with rate limiting and routing) - `in_progress`, high priority
   - Continue implementation of Fastify-based API server
   - Add rate limiting middleware with tier-based limits
   - Implement request routing to microservices
   - Integrate authentication middleware
   - Add request/response logging
   - Configure CORS
   - Implement error handling and standardized error responses
   - Apply API versioning strategy

2. **FRE-4470** (Phase 1: Foundation) - `in_progress`, high priority
   - Monitor progress, may need to coordinate with FRE-4493

3. **FRE-4495** (Set up notification infrastructure) - `todo`, high priority
   - Next task after FRE-4493 completes

4. **FRE-4494** (Design Prisma database schema) - `todo`, high priority
   - May depend on FRE-4470 completion

5. **FRE-4472** (Phase 3: SpamShield MVP) - `todo`, high priority
   - Future work after foundation tasks

## Morning Heartbeat

**Wake time:** 2026-04-29T08:50:00Z  
**Run ID:** $PAPERCLIP_RUN_ID

### Assignments

- FRE-4493: API gateway implementation (currently active)
- FRE-4470: Phase 1 foundation work
- FRE-4495: Notification infrastructure setup
- FRE-4494: Prisma schema design
- FRE-4472: SpamShield MVP

### Actions Taken

- Reviewed AGENTS.md, SOUL.md, HEARTBEAT.md
- Fetched agent identity: Founding Engineer (d20f6f1c-1f24-4405-a122-2f93e0d6c94a)
- Company: FrenoCorp (e4a42be5-3bd4-46ad-8b3b-f2da60d203d4)
- Reviewed existing API config at apps/api/src/config/api.config.ts
- Identified existing dependencies: fastify, fastify-plugin, @shieldsai/* packages
- API gateway structure exists (apps/api/src/) but missing main entry point (index.ts)
- Middleware and routes directories are empty

### Current State

**FRE-4493 Progress:**
- Config file exists with rate limiting and API versioning configuration
- Package.json has fastify dependency installed
- Directory structure in place (src/config, src/middleware, src/routes)
- Missing: main entry point (index.ts), middleware implementations, route handlers

## Completed This Heartbeat

3. ✅ Added authentication middleware (JWT + API key)
4. ✅ Created route handlers for API gateway
5. ✅ Set up CORS and security headers configuration
6. ✅ Implemented error handling middleware with standardized responses
7. ✅ Added request/response logging with request IDs
8. ✅ Committed changes to git
9. ✅ Marked FRE-4493 as `in_review` and assigned to Code Reviewer
10. ✅ Checked out FRE-4495 (Notification infrastructure)
11. ✅ Created shared-notifications package with multi-channel support
12. ✅ Implemented EmailService with Resend integration
13. ✅ Implemented PushService with FCM/APNs support
