## Codex Review Resolution

Command:
codex exec review --dangerously-bypass-approvals-and-sandbox 'review the diff of current jj revision, you can use jj diff to see changes'

Finding:
- [P2] Generate valid doc tuples for small manifest sets in `tools/ci/generate-infrastructure.py:202-206`.
  When fewer than four manifests declare model guides, unconditional separators produced empty tuple elements, resulting in invalid Python syntax.
Disposition:
- RESOLVED by orchestrator: Chunked model directory strings into populated slices of up to 3 elements, joined with valid line breaks, added trailing comma for single-element tuples, and added `compile(docs_py, "check-docs.py", "exec")` to `tests/tools/generate_infrastructure_test.py`.
- Re-ran all gates: `generate-infrastructure.py --check` (exit 0), `generate_infrastructure_test.py` (9/9 pass, exit 0), `check-format.py` (exit 0), `check-docs.py` (exit 0), `legacy hosted PR check` (exit 0).
