Brain routing rule (local vs shared, where each thing goes)

Each operator runs the same substrate pattern: a local personal brain plus a federated shared brain. The question is which content goes where.

When ambiguous → mirror to shared by default. The cost of over-sharing is one duplicate page; the cost of under-sharing is missing context the partner would have benefited from. (Per the joint-scoping principle established 2026-07-05.)

Drafting content into the wrong brain by accident — the partner sees a "felt right" draft that was supposed to be private. Audit by reading the URL prefix on every MCP write; cross-check gbrain sources list when in doubt.

A Hermes instance can have both a local and a federated brain MCP server mounted at once. The tool names look almost identical:
