One key per registration in the module's servers bucket — all.<server> or
<node>.<server> — watched by every node, so a node assigned after a
registration takes it at start, which the mcp.registered event could not do.
Also narrows apply()'s refusal by hand: the builder compiles without strict,
where the discriminated union does not narrow and the build failed.
Events carry what happened and no secret; tokens travel on requests (design 32 §10). The manager's
licence.rotated/switched events make the module ask anthropic-licence-manager.current; at start it
asks once to catch up. A refresh token appearing in the credentials file is a login: it is pushed to
the manager's adopt at once, sealed to the manager's key — the one time a refresh token travels. A
switch replaces the old licence's grant whole, removes the API key and its helper, and rewrites
oauthAccount in ~/.claude.json. New tools register and unregister MCP servers on this node, or with
nodes: all / a list via an mcp.registered event every node consumes; called for one node, the
answer names the other nodes running claude-code. 26 tests.
Every bundle is now a child speaking MCP over stdio, so stdout is the channel: the module logs on
stderr. The managed CLAUDE.md teaches mesh_search, mesh_describe, mesh_call, mesh_overview and
mesh_machine with addresses (<seat>.<verb>, <node>/<module>.<tool>) instead of flat tool names.
A hand-over is applied whatever the trailing render says; a failed render is reported beside it.
Proven over stdio as the runtime drives it: five tools listed, a key made on first use, a sealed
switch writing an access-token-only 0600 credentials file that keeps unknown keys.
The module owns /etc/claude-code: managed-mcp.json lists the console as `mesh` over HTTP on
loopback plus the servers in its mcp_servers setting (exclusive, by the operator's choice — the
https rule of managedMcpServers refuses a loopback console); managed-settings.json carries the
attribution convention, keeps claude.ai connectors, and adds the key-helper only for an API-key
licence; CLAUDE.md says how a session here works. Rendered whenever the runtime collects the
tools, written only on change, through the operator account's sudo. Under the home, only the
credentials file, only on a hand-over. Nothing declared under a home or /etc; the console's
port comes from node-tools' mcp-endpoint (mesh-tools #34).
The parts of the agent module that hold whichever way the console is registered: X25519 +
HKDF + AES-GCM from Node's own library so the bundle carries no dependency; the predecessor's
lineage rule (rotation only if newer, a re-issue adopted, a switch regardless) with its
incidents as tests; an atomic 0600 write that strips any refresh token and keeps keys it does not
know; the account read from the agent's own state file. Manifest and renderer follow.
