Phase C of vendor-agnostic model-access (ADR 0050/0054). Two TypeScript
runtime modules:
- anthropic-manager: the refresh token is sealed at rest to the manager
node's own key (atrest.ts, envelope encryption over X25519) and opened
ONLY on the manager node. adopt seals the first envelope; refresh opens
it, calls the Anthropic OAuth token endpoint, re-seals a rotated refresh
token, and hands the control plane only the access token plus the opaque
envelope. Also polls licence-grain usage (ADR 0054).
- anthropic-consumer: writes the delivered access token to
~/.claude/.credentials.json, access-token-only, atomically (the refresh
token is never delivered); reports session-grain usage from the CLI
transcripts; a fail-closed identity guard (expected-uuid plumbing is a
flagged TODO).
Both run as scheduled containers (ADR 0053). Pure logic covered by
node --test fixtures (at-rest round-trip, credential strip, transcript
sum, refresh merge).
