description: Local CTO packet for the guarded Codex inactive-thread archive executor.
---
# CTO Codex Retention Archive Executor Packet
Local planning SOT only. Not a Core Protocol. Not active Core authority.
## Claim
Codex retention cleanup now has a guarded archive-only executor. Default mode is dry-run. Mutation requires an exact approval token.
## Context
`CTO-WORK-094` defined the retention policy. The next vertical move is executable archive-only cleanup, not more Core output tuning.
This packet keeps the destructive boundary intact. It prepares phase 2 only: set inactive Codex thread records to archived. It does not delete session JSONL, truncate logs, checkpoint, vacuum, read transcript bodies, or import transcripts into Core.
## Executor
Dry-run:
```bash
python3 tools/archive_codex_inactive_threads.py
```
Focused check:
```bash
python3 tools/archive_codex_inactive_threads.py --check
```
Approved archive-only execution:
```bash
python3 tools/archive_codex_inactive_threads.py --execute --approval-token "I approve CTO-WORK-095 archive-only Codex threads older than 7 days."
```
## Guardrails
- candidate selection reads only `id`, `rollout_path`, `updated_at`, `archived`, and file size;
- raw transcript bodies are not read;
- thread title, preview, and first user message are not read;
- default execution is dry-run;
- execution requires the exact approval token;
- backup runs before DB mutation;
- mutation is limited to `threads.archived=1` and `archived_at`;
- session JSONL deletion is blocked;
- log deletion or truncation is blocked;
- SQLite checkpoint or vacuum is blocked;
- Core source mutation is blocked.
## Backup
Before any approved archive update, the executor backs up:
- `state_5.sqlite`;
- `logs_2.sqlite`;
- `state_5.sqlite-wal` when present;
- `state_5.sqlite-shm` when present;
- `logs_2.sqlite-wal` when present;
- `logs_2.sqlite-shm` when present.
Default backup path is inside `~/.codex/backups/cto-codex-retention/<timestamp>/`.
## Approval Boundary
Still blocked without separate approval:
- delete archived session JSONL;
- delete or truncate Codex logs;
- run SQLite checkpoint or vacuum;
- read raw transcript bodies;
- import raw transcripts into Cortex OS Core.
## Decision
Use this executor only after JP gives the exact archive-only approval token. Keep delete, log cleanup, checkpoint, and vacuum as later decisions.
## New Issues
- must-fix: obtain exact approval token before running `--execute`.
- follow-up: after archive-only execution, re-run retention planner and decide whether deletion is still worth separate approval.
