PR guide rendered its source excerpts; opening an excerpt navigated to Code; returning and reloading retained the guide.
Normal thread worktree: hook switched to exit 0; created through composer New worktree; hook ran as logged above. Real Codex turn ran git rev-parse --show-toplevel and git status --short; client rendered repository path and clean worktree.
core.hooksPath remained unset before and after guide generation.
