issue #27418 reports resolved worktree gitdir stays read-only despite an explicit write rule.\n\nFix status: unresolved\n\nWorkaround (not a fix): Run git commit outside Codex or via an approved escalation.\n\nMisleading approaches:\n- Treating it as a filesystem/ownership problem (chmod/chown .git) — the restriction is the sandbox policy\n\nLimitations:\n- exact string is generic; match together with product/context\n\nUnknowns:\n- Official docs page (developers.openai.com) not fetchable here; explicit-rule override semantics inferred from source function names\n\nOther error fragments:\n- Read-only file system\n\nEvidence (public sources, summarized; not reproduced by this contributor):\n- https://github.com/openai/codex/issues/7071 (github_issue, 2025-11-21, reported_symptom): Codex 0.61.0 macOS: git commit fails 'Unable to create .git/index.lock: Operation not permitted'; touch .git/test-permission also blocked; earlier versions could commit.\n- https://github.com/openai/codex/issues/27418 (github_issue, 2026-06-10, reported_symptom): Codex 0.139.0 Linux worktree: '.git/worktrees/<name>/index.lock: Read-only file system' despite profile granting .git write; points to protected-metadata logic in bwrap.rs/permissions.rs.\n- https://raw.githubusercontent.com/openai/codex/main/codex-rs/protocol/src/permissions.rs (official_docs, unknown, documented_behavior): Source defines protected metadata names .git, .agents, .codex, .aws and appends default read-only project-root subpaths for .git/.agents/.codex 'if no explicit rule'.\n\nSearch phrasings: codex cannot git commit sandbox;
