Detailed Entries
Rust Submodule Divergence
- Context: Vendored
codex-rsmust track upstream without accumulating local hacks. - Mitigation Actions
- Establish weekly cron to fetch upstream and open PR if divergence detected.
- Store patches under
patches/codex-rs/and re-apply automatically. - Require changelog entry and integration tests before bumping commit.
- Monitoring
mix codex.verifyincludesgit status vendor/codexcheck.
Fixture Drift vs Python
- Context: Golden JSONL fixtures can fall out of date as Python evolves.
- Mitigation
- Maintain manifest with SHA256 per fixture.
- Nightly CI job regenerates fixtures and fails if checksum changes.
- Use GitHub issues template for documenting accepted fixture diffs.
Tooling API Mismatch
- Context: Tool registry/auto-run semantics must mirror Python.
- Mitigation
- Schedule design review with Python maintainers before implementation.
- Build contract tests for tool invocation transcripts.
- Maintain parity checklist for tooling features (decorators, metadata, approvals).
Approval Deadlocks
- Context: Misconfigured approval policies could hang turn execution.
- Mitigation
- Enforce default timeout with abort + error surface.
- Provide async queue implementation with supervision.
- Stress test using Supertester chaos helpers (simulate slow/failed approvals).
Coverage Regression
- Context: As features land, coverage/lint gates must remain enforced.
- Mitigation
- Set baseline threshold in
mix coveralls. - Document process for adjusting baseline only with QA approval.
- Integrate coverage trend reporting into CI dashboards.
- Set baseline threshold in
