Portable state. Protected-backend boundary.

Build RD1-210-0742 keeps the Combined Feed Engine and Attention Workflow intact while introducing a portable RelayDesk Core state envelope and the schema boundary for a future dedicated PostgreSQL/Supabase backend.

What changed

• RelayDesk Web App now identifies as Web 2.1.0 Core Foundation.
• Connectors includes a Core Foundation card with Export Core State and Clear Attention controls.
• Core export contains Test Lab identity/messages, RelayDesk attention state and basic UI preferences.
• Matrix access tokens are explicitly excluded from exported Core state.
• Provider transport remains separate from RelayDesk-owned state.
• Dedicated RD1 backend remains intentionally unattached until an isolated project is available.

The connected Supabase account currently exposes BrightWatcher Dev/Prod only. RelayDesk 2.1.0 does not reuse or modify those databases.

Production target

Authenticated RelayDesk APIs, isolated PostgreSQL storage, Row Level Security, durable attention state, connector-account metadata, audit timestamps and server-side secret handling. Matrix remains pluggable.
