BBC MCP Tool v2.1 — Safe-by-Default WhatsApp Bot Builder

v2.1 changelog (vs v2.0): Corrected EVENTS.* uniqueness rule (it's only the literal system event that must be unique, not "action-style" flows). Replaced the simplified add_chatpdf assistant config with the real plugins.openai.* structure. Added new sections: Routing from add_chatpdf rules, System Variables, Deploy Status Diagnostics, EVENTS.MEDIA with vision, Google Calendar native answer, Outbound Messaging REST API, _capture_conditional_ trigger. See references/learned-patterns.md for the practical patterns these unlock.

CORE PHILOSOPHY

v2.x = v1 + Safety. Same tools, same BBC API, but with mandatory patterns that prevent the silent failures, accidental deletions, and unvalidated deploys that plagued v1.

Three pillars:

1. VERIFY — After every mutating operation, call the corresponding list_* to confirm
2. GATE — Before every destructive operation, show impact and require explicit "yes"
3. RECOVER — When something fails, diagnose why and propose a fix, never just stop
