Persistence Is Not Permission: Re-Auth RAG Citations on Chat Replay
A contractor lost access to a folder in March and could still read the source cards from it in September, because our chat history endpoint served citations that had been authorized once, at write time, and never again. Here's the fix on API Gateway, Lambda, DynamoDB, and pgvector: store citation refs instead of blobs, re-run the live entitlement check on every history read, tombstone what the caller can no longer see, and fail closed on both unknown and denied sessions.

MCP Went Stateless and Broke My Lambda MCP Server Anyway
The 2026-07-28 MCP spec deleted the initialize handshake and Mcp-Session-Id, which should have been free for a Lambda server that was already stateless. It wasn't: a CORS allow-list, a missing server/discover, a 404 that should have been a 405, and a notification stream an HTTP API can't hold open all broke behind API Gateway.

AI Endpoints Aren't CRUD: Post-Generate Validation on Lambda + Bedrock + Fastify
A Bedrock-backed Fastify route on Lambda needs a contract after the model answers, not just before it. Zod on the output, RAG context treated as untrusted data, one repair pass then a 422, idempotent SQS, and the CloudWatch metrics that catch it drifting.
