Type registry (briefing / console-trace / behaviour TAG / agent-commit +
spawn/finding/refactor/test/session-merge/decision subtypes) with reflexive
transitive is-a? and create-only register-type!. Agent commits ARE git
commits (:agent-type rides as an open field, participates in the CID, DAG
machinery applies unchanged). 65/65.
