Server-to-Server Sync API with strict retry enforcement.

First Sync (No History):

• Call without session_id to start new session
• Returns ALL historical memories (paginated)
• No time window restriction
• Rate limited: 2 hours between sync sessions

Incremental Sync (Has History):

• Returns only new memories since last completed sync
• Paginated results

Pagination:

• Use session_id + cursor from previous response to fetch next page
• Cursor-based pagination for consistency
• Max 2 retries per cursor (3 total attempts)

Rate Limiting:

• New sessions: 2-hour minimum between syncs
• Pagination within session: No rate limit
• Cursor retry limit: 2 retries per cursor

Session Management:

• Sessions expire after 1 hour of inactivity
• Session auto-completes when all pages fetched

Example Flow:

# Start first sync
GET /sync?limit=100
→ Returns: session_id=abc123, cursor=page1, memories=[...]

# Continue pagination
GET /sync?session_id=abc123&cursor=page1&limit=100
→ Returns: cursor=page2, memories=[...]

# Retry on error (max 2 retries)
GET /sync?session_id=abc123&cursor=page1&limit=100
→ Returns: Same data (idempotent)
