📋 Decision Context

Question:

Session 121 milestone: Redis + Railway consolidation plan finalized

Task: Session 121: Railway consolidation + Redis for all APIs - milestone

🎯 Decision Made

Chosen:

Comprehensive plan created with clear split between codebase changes (code agent) and infrastructure changes (browser agent)

Options Considered:

• No alternatives documented

💭 Reasoning

CODEBASE CHANGES (code agent): (1) Create shared RedisModule in @libs-api/backend-core with ioredis, graceful fallback, health checks, (2) backend-api: Redis ThrottlerModule storage, magic link store, OAuth cache, Socket.IO Redis adapter, (3) backend-ai-api: Redis ThrottlerModule storage, make DistributedLockService require Redis in prod, WebSocket rate limit maps to Redis, Socket.IO Redis adapter, (4) backend-docs-api: Redis ThrottlerModule storage, Socket.IO Redis adapter, (5) backend-vitto-api: Migrate ChannelRateLimiter + PromptCache + ResponseCache + CircuitBreaker to Redis, (6) Add ioredis + @socket.io/redis-adapter dependencies. INFRASTRUCTURE CHANGES (browser agent): (1) Create consolidated Railway project 'GoGrab Platform', (2) Deploy Redis service, (3) Re-create each API service in consolidated project (same GitHub repos), (4) Configure REDIS_URL via reference variables, (5) Move custom domains, (6) Verify private networking, (7) Decommission old projects. ORDER: Code first (with fallback), then infrastructure migration.
