Implement the core write-through cache pattern for node creation. This is the architectural foundation of the application. Changes: - Add @google/generative-ai dependency for embeddings - Create lib/db.ts: SurrealDB connection helper with JWT auth - Create lib/ai.ts: AI embedding generation using text-embedding-004 - Create app/api/nodes/route.ts: POST endpoint implementing write-through cache Write-through cache flow: 1. Authenticate user via SurrealDB JWT 2. Publish node to ATproto PDS (source of truth) 3. Generate 768-dimensional embedding via Google AI 4. Cache node + embedding + links in SurrealDB Updated schema to use 768-dimensional embeddings (text-embedding-004) instead of 1536 dimensions. Security: - Row-level permissions enforced via SurrealDB JWT - All secrets server-side only - ATproto OAuth tokens from secure cookies 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
