jochen 15b2e6b86e The licence manager, in Go, and claude-code's half of ADR 0206
claude-licence-manager holds the anthropic-licence-manager seat: it reads
every node's holdings state, adopts a login it does not hold by refreshing
it (newest first, once per account), keeps each grant alive under a lease,
publishes what each consumer should hold as its bindings state with a
generation, and answers current sealed to the consumer's key. Postgres
store prepared by a run-once step; grants encrypted with the vault's key.

claude-code reports what its node holds (fingerprints and account, never a
token), hands its grant over only when the manager asks, watches its
binding and fetches the token on a newer generation, and writes
access-token-only. Its ask now reads the runtime's answer as a value and
addresses seats as seats.

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:

  1. A report with a refresh token it does not hold is a candidate.
  2. It asks that node's claude_code_grant, giving its public key, and receives the grant sealed to it.
  3. 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.
  4. Several nodes logged in to one account: newest login first; the rest are never exchanged.
  5. 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 the agent module's own format, byte for byte, and a test opens one the TypeScript sealed (and has TypeScript open one Go sealed, where node and a built claude-code are beside it).
