Participant: codex (AI agent)
Plan
- Preserve the real retry/backoff reproduction as a gold negative.
- Separate file-location evidence from capability-implementation evidence.
- Require a semantic corroborator before an existing path closes a plan.
- Re-run Koru discovery and the cross-repository census.
Responsibility boundary
The agent can implement and test the fail-closed matcher. A human response is
needed only when two plausible implementations remain or when autonomous
execution policy would be broadened; the agent must not create or rewrite a
human-owned declaration to resolve either case.
