Exact maintained-agent prompt

# Packet PR Maintenance Prompt (`0.144.6`)

This template renders the exact maintained-agent prompt for `codex` packet execution.
`docs/agents/lifecycle/codex-maintenance/HANDOFF.md` remains canonical and `governance/pr-summary.md` is derivative.

## Goal

Execute the automated maintenance packet for `codex` target `0.144.6`.

## Frozen request contract

- Read `docs/agents/lifecycle/codex-maintenance/governance/maintenance-request.toml` before changing code or docs.
- Read the packet-owned `support_surface_audit` block before deciding whether the run can succeed.
- Treat `docs/agents/lifecycle/codex-maintenance/HANDOFF.md` as canonical for writable surfaces, read-only inputs, ordered commands, green gates, and recovery.
- Treat `.github/workflows/agent-maintenance-open-pr.yml` as the opening workflow source.
- Do not write outside the execution contract frozen in the request packet.

## Manifest inputs

- `cli_manifests/codex/README.md`
- `cli_manifests/codex/VALIDATOR_SPEC.md`
- `cli_manifests/codex/RULES.json`
- `cli_manifests/codex/SCHEMA.json`
- `cli_manifests/codex/current.json`
- `cli_manifests/codex/latest_validated.txt`
- `cli_manifests/codex/wrapper_coverage.json`

## Required workflow

1. Compare the current validated baseline from `cli_manifests/codex/latest_validated.txt` against the target `0.144.6` artifacts.
2. Use `support_surface_audit` to classify newly discovered non-TUI surface, preexisting non-TUI debt, required uplifts, and allowed deferrals.
3. Land bounded wrapper/backend/manifest/publication updates for every row in `required_uplifts_this_run`.
4. Refresh or create version-scoped manifest artifacts under `cli_manifests/codex/snapshots/0.144.6/`, `cli_manifests/codex/reports/0.144.6/`, and `cli_manifests/codex/versions/0.144.6.json` as required by the packet.
5. Leave closeout manual; record it only with `close-agent-maintenance` after the declared green gates pass.

## Done criteria

- Changes stay within the writable surfaces frozen in `docs/agents/lifecycle/codex-maintenance/governance/maintenance-request.toml`.
- No newly discovered non-TUI surface remains unresolved unless the packet records one allowed deferral.
- `cargo run -p xtask -- codex-validate --root cli_manifests/codex` passes.
- The remaining ordered commands and green gates from `docs/agents/lifecycle/codex-maintenance/HANDOFF.md` pass or are captured in maintainer follow-up notes.

Summary

• Updated the Codex 0.144.6 maintainer follow-up to confirm that the frozen support-surface audit requires no new uplifts and retains only the two authorized codex completion deferrals. docs/agents/lifecycle/codex-maintenance/governance/maintainer-follow-up.mdL3-L10
• Recorded the canonical relay blocker: the dry run prepared run 20260726T062131Z, but the environment has no codex executable, so write mode could not proceed. docs/agents/lifecycle/codex-maintenance/governance/maintainer-follow-up.mdL12-L15
• Documented the independently passing gates and the four existing agent_maintenance_execute test failures that prevented make preflight from completing. docs/agents/lifecycle/codex-maintenance/governance/maintainer-follow-up.mdL17-L40
• Kept closeout manual and documented the required maintainer recovery steps. docs/agents/lifecycle/codex-maintenance/governance/maintainer-follow-up.mdL42-L48
• Committed the changes as bafaf47 (docs(codex): record maintenance packet gate blockers) and created the follow-up PR metadata with title “docs(codex): record 0.144.6 packet execution blockers.”

Testing

• ✅ cargo fmt --all
• ✅ cargo run -p xtask -- codex-validate --root cli_manifests/codex
• ✅ cargo run -p xtask -- support-matrix --check
• ✅ cargo run -p xtask -- capability-matrix --check
• ✅ cargo run -p xtask -- capability-matrix-audit
• ✅ git diff --check
• ✅ ./scripts/check_repo_hygiene.sh
• ⚠️ cargo run -p xtask -- execute-agent-maintenance --dry-run --request docs/agents/lifecycle/codex-maintenance/governance/maintenance-request.toml (environment lacks the configured codex executable). docs/agents/lifecycle/codex-maintenance/governance/maintainer-follow-up.mdL12-L15
• ❌ make preflight (four existing crates/xtask/tests/agent_maintenance_execute.rs tests failed; the packet’s frozen writable surfaces exclude their implementation). docs/agents/lifecycle/codex-maintenance/governance/maintainer-follow-up.mdL27-L40
