NotebookLM

Note (Apr 15 2026): Aitable.ai (space spc63cnXLdMYc) is the primary SSoT for human business ops (e.g. Clients, Brands, credentials, decisions — see docs/AITABLE_SCHEMA.md). There is no “Products” datasheet as a sheet name; don’t conflate that with NotebookLM. NotebookLM remains for research, methodology, and specs — not live customer row state. Knowledge Hub

Critical

• 36 notebooks are the spec/methodology source of truth — codebase has implementation, notebooks have specs.
• Phase 3 MCP proxy active (2026-05-01) — use mcp__notebooklm__query, mcp__notebooklm__list_notebooks, mcp__notebooklm__summary. No Selenium, no Chrome, no cookie management.
• Auth managed by worker — if you get AUTH_EXPIRED (503), the worker's notebooklm-cookie-refresh cron is stale. Check agent_findings for notebooklm-cookie-refresh failures, then re-run notebooklm-mcp-auth on the operator machine and seed via tools/seed-notebooklm-session.ts.
• Never use WebSearch when NotebookLM is the right tool — tools are chosen for access control and context.
• Conflict resolution: When sources conflict, query NotebookLM 1dc7ce26 for hierarchy and cross-reference map.
• Some notebooks are empty — check source_count before querying.

Auth Flow (Phase 3 — worker-hosted)

The Phase 3 proxy routes through https://worker.superseller.agency/api/internal/notebooklm/*. Cookie management is worker-side. From Claude Code:
