Implemented the node editor page and AI-powered link suggestions:
1. Node Editor Page (/editor/[id]):
- Form with title and body fields using Mantine
- Pre-fill support from query params (for chat redirects)
- "Find Related" button to discover similar nodes
- "Publish Node" button to save to ATproto + SurrealDB
- Display of suggested links with similarity scores
- Mantine notifications for success/error feedback
2. Suggest Links API (/api/suggest-links):
- Authenticates using SurrealDB JWT cookie
- Generates embedding for draft text using Google AI
- Performs vector similarity search using SurrealDB
- Returns top 5 most similar nodes with cosine scores
- Enforces row-level security (users only see their nodes)
3. Magnitude Tests:
- Editor page rendering
- Pre-filled form from query params
- Publishing new nodes
- Form validation
The editor integrates with the existing /api/nodes write-through
cache from Step 6, completing the node creation workflow.

Fixed multiple issues with the @atproto/oauth-client-node integration:
1. OAuth State Store:
- Changed from SQL WHERE queries to SurrealDB record IDs
- Use `oauth_state:⟨${key}⟩` pattern for direct lookups
- Fixes "Parse error: Unexpected token" issues
2. OAuth Session Store:
- Changed from SQL WHERE queries to SurrealDB record IDs
- Use `oauth_session:⟨${did}⟩` pattern for direct lookups
- Implement proper upsert logic with select + merge/create
3. OAuth Client Configuration:
- Use loopback pattern with metadata in client_id query params
- Format: `http://localhost/?redirect_uri=...&scope=atproto`
- Complies with ATproto OAuth localhost development mode
4. Auth Callback:
- Remove getProfile API call that requires additional scopes
- Use DID directly from session for user identification
- Simplify user creation in SurrealDB with record IDs
5. Login Page:
- Change from GET redirect to POST with JSON body
- Properly handle errors and display to user
The OAuth flow now works end-to-end:
- User enters handle → redirects to Bluesky OAuth
- User authorizes → callback exchanges code for tokens
- Session stored in SurrealDB → user redirected to /chat

Replace manual OAuth implementation with official @atproto/oauth-client-node library to properly support DPoP (Demonstrating Proof of Possession) authentication.
Changes:
- Added @atproto/oauth-client-node dependency
- Created OAuth state store (SurrealDB-backed) for CSRF protection
- Created OAuth session store (SurrealDB-backed) for token persistence
- Created OAuth client singleton with localhost exception for development
- Rewrote /api/auth/login to use client.authorize()
- Rewrote /api/auth/callback to use client.callback() with DPoP
- Updated lib/auth/session.ts with getAuthenticatedAgent() for ATproto API calls
- Updated db/schema.surql with oauth_state and oauth_session tables
- Added scripts/apply-schema.js for database schema management
- Created plans/oauth-dpop-implementation.md with detailed implementation plan
- Removed legacy lib/auth/atproto.ts and lib/auth/oauth-state.ts
- Updated .env to use localhost exception (removed BLUESKY_CLIENT_ID)
The OAuth client now handles:
- PKCE code generation and verification
- DPoP proof generation and signing
- Automatic token refresh
- Session persistence across server restarts

Step 7 Updates (AI Chat with Structured Output):
- Created lib/ai-schemas.ts with Zod schema for NodeSuggestion
- Updated app/api/chat/route.ts:
- Changed import from 'ai' to '@ai-sdk/react' for streamText
- Added tools configuration with 'suggest_node' tool using NodeSuggestionSchema
- Added persona support with dynamic system prompts
- Extracts persona from request data object
- Rewrote app/chat/page.tsx:
- Changed from server component to client component ('use client')
- Uses useChat from '@ai-sdk/react' (fixes broken 'ai/react' import)
- Added experimental_onToolCall handler for node suggestions
- Redirects to /editor/new with AI-generated title/body as query params
- Integrated MicrophoneRecorder for voice input
- Added persona support (currently hardcoded to 'Socratic')
- Added tests/magnitude/07-chat.mag.ts with tests for:
- Basic chat functionality
- AI-triggered node suggestions with redirect to editor
Auth Callback Fixes:
- Fixed app/api/auth/callback/route.ts:
- Changed to use agent.api.com.atproto.server.getSession() to fetch session
- Previously used agent.getSession() which returned empty did/handle
- Added user upsert to SurrealDB (INSERT...ON DUPLICATE KEY UPDATE)
- Fixed variable references (session.did -> did, session.handle -> handle)
- Properly creates user record before minting JWT
CLAUDE.md Updates:
- Added git commit HEREDOC syntax documentation for proper quote escaping
- Clarified that this project allows direct git commits (no PGP signatures)

Implement serverless-friendly Deepgram token generation.
This provides a secure, stateless way for clients to use Deepgram's
real-time streaming without exposing the main API key:
1. Client requests temporary token from Next.js API
2. Server generates short-lived (60s) token with 'member' scope
3. Client uses token to connect directly to Deepgram WebSocket
This architecture bypasses Vercel's serverless WebSocket limitations
while maintaining security by keeping the main Deepgram API key
server-side only.
Security:
- Main API key never exposed to client
- Temporary tokens expire in 60 seconds
- Minimal 'member' scope permissions

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
