# Codex cloud value-availability review

Separate documented phase availability from generated copies and your own observations.

Synthetic values and unexecuted cloud checks. No environment or provider task is launched.

## A phase-based review

### Setup

Repository checkout and approved dependency preparation

Note: Configured secrets are documented as available here

### Agent phase

Task tools and configured agent network policy

Note: Configured secrets are documented as removed

### Retained state

Files, logs and cached environment created during setup

Note: Review copies independently

| Value or copy | Expected from documentation | Observed |
| --- | --- | --- |
| Ordinary configured variable | Setup and agent phases | Untested |
| Configured setup secret | Setup only | Untested |
| Setup-shell export | Does not automatically persist | Untested |
| Generated file or log | Requires its own review | Unreviewed |
| Cached environment resume | Record lifecycle and maintenance | Untested |

## Review checklist

- [ ] Give each value a purpose and source
  Record whether it is ordinary configuration or a setup-only secret.
- [ ] Review outputs created by setup
  Variable removal does not establish handling of files or logs written by your scripts.
- [ ] Record initial and cached lifecycle evidence
  Use only fake markers and keep prerequisites separate from the observed phase result.
