Commits made by coding assistants are currently indistinguishable from
hand-typed ones. state-hub has two commit identities, tegwick and
custodian-sync; only Claude Code is identifiable, and only via a
Co-Authored-By trailer added by a prompt instruction. Codex and Grok add
nothing.
Establishing on 2026-08-21 that a 14-hour Codex session had not collided
with a concurrent Claude session required correlating process tables against
commit timestamps, and could only conclude 'not me and not the sync bot'.
Adds git trailers carrying assistant, model, and process, applied by a
prepare-commit-msg hook wired through core.hooksPath. Author stays tegwick
deliberately -- assistants run under Bernd's account because he supervises,
and the trailers add provenance rather than a second actor.
Scopes explicitly to the coding-assistant category and leaves room for
kaizen agents (own agent ids and accounts) and scheduled OpenRouter runs as
separate future mechanisms.
