The manager binds the node a login was adopted from to that login's licence,
switching it if it was bound to another; serves public_key; adopt takes a
key sealed to it. claude-code gains claude_code_add_api_key: read a file on
this node, seal, hand to adopt, remove the file, optionally switch here.
The module is one Go binary the runtime launches: the renderer (its
instruction file held byte for byte to the TypeScript one it replaces),
the credentials and identity files, the licence flow of ADR 0206 and the
MCP servers in state. Keeps the TypeScript module's key files, so a node
moving to it keeps its key. The npm package, its tests and its build go.
Both binaries were run together under the real runtime on a test bus with
postgres and a stub vendor: a login was adopted by one exchange, the node
bound and handed an access token, its file left with no refresh token, and
no token in either state.
