The check looked for "rt" in a random base64 ciphertext, which holds it about one time in seventy, and failed mesh-catalog #141's repo check by chance.
claude-licence-manager
Holds the anthropic-licence-manager seat: every Anthropic licence the mesh has, kept alive by one
rotation source, and handed to each consumer sealed (novox/hq ADR 0183, ADR 0206, design 39).
How a licence comes to exist
Nothing is configured. Every node running claude-code reports what it holds as that module's
holdings state — the account, fingerprints and expiries, never a token. This module reads every report
when it starts and watches them:
- A report with a refresh token it does not hold is a candidate.
- It asks that node's
claude_code_grant, giving its public key, and receives the grant sealed to it. - It refreshes it. If the vendor exchanges the token, the grant is this module's — encrypted at rest with the key the vault made for it — and from then on it is the only refresher. If not, the candidate is recorded dead and nothing is adopted.
- Several nodes logged in to one account: newest login first; the rest are never exchanged.
- A node reporting that account and bound to nothing is bound to it.
Each node is then handed an access token only, so the agent there never refreshes, and a refresh token appearing on a node later can only be a person's login — which wins if it refreshes.
An API key enters through adopt, from a file on this module's node.
What each consumer holds
This module's bindings state: one key per consumer (a node's name) with the licence, its kind and a
generation that grows with every rotation and switch. claude-code watches its own key and, on a newer
generation, asks current with its public key.
The seat's verbs
licences, bindings, bind, switch, release, refresh, usage, adopt, current — through
the console as anthropic-licence-manager.<verb>. No answer carries a token.
Settings
settings.json in the state directory: cadence_minutes (240), floor_minutes (60),
failures_to_notify (3), cooldown_hours (24), refresh_warn_days (3).
Events
licence.adopted, licence.refused, licence.failing, usage.read — none carries a secret.
Code and tests
Go, one binary (cmd/claude-licence-manager): the seat's verbs and the daemon in one launched bundle,
prepare as the run-once preparation step. The sealed box is claude-code's own format, byte for byte —
the two modules carry the same seal.go — and a test opens one sealed by the TypeScript agent module the
Go one replaced, so the format is the one already on the machines.
