- Codex customization layers
- skill/plugin packaging
- automation UI and cadence controls
- team/workspace governance features
- exact config keys and commands

obsolete_when:
- Codex introduces an integrated team workflow primitive that replaces several current customization layers.
- Official customization guidance materially changes.
