Interfaces

• fnpqnn-gateway CLI: use only through the documented repository route.

• MCP server: use only through the documented repository route.

• Typed adapter boundary: use only through the documented repository route.

• Suite auth audit: validates the twelve repository adapter templates and fails closed on missing policy or forbidden secret material.

• Fingerprint acceptance: records a bounded, non-secret approval reference after provider-native authentication.

• Application boundary: every product owns its actual login UI, callback, account binding, session lifecycle, logout, and recovery.

Interface contract

Inputs must be explicit, outputs must be inspectable, errors must be returned as errors, and consequential external actions require human approval.

Compatibility

Treat undocumented endpoints, commands, and browser controls as unsupported. Confirm the current repository version before integrating another system.
