APPLIED GUIDE
Codex deployment and release evidence
A reliable release records the source commit, artifact or image identifier, target environment, migration and backup state, health checks, user-journey results, and rollback command. Evidence should come from the deployed runtime, not only the build machine.
Recommended process
A reliable release records the source commit, artifact or image identifier, target environment, migration and backup state, health checks, user-journey results, and rollback command. Evidence should come from the deployed runtime, not only the build machine.
- Confirm repository, branch, host, and runtime.
- Create a backup or reversible release point.
- Run build, tests, security checks, and migration validation.
Review checklist
Use this checklist before accepting the output or turning it into an action.
- Verify deployed version, health, logs, and critical journeys.
- Record exact rollback and recovery steps.
CONCRETE EXAMPLE
Observable result
A web release is identified by commit and image digest, passes health and signup checks on production, and keeps the previous image and database backup available.
- Confirm repository, branch, host, and runtime.
- Create a backup or reversible release point.
- Run build, tests, security checks, and migration validation.

Frequently asked questions
What is the minimum production proof?
Confirm the deployed version, a health endpoint, the affected user journey, relevant logs, and a workable rollback path.
Should Codex edit before reading the repository?
No. It should first locate the real code path, current branch, relevant instructions, and existing changes.
