The Provider Map And Safety Rails
You can explain which files changed, why sessions stayed safe, and which provider route is operational.
Simple layer
Codex now has a control plane: one registry, profile files for each model, custom agents for roles, and a proxy route that actually passed real Codex execution.
Technical layer
The safe unit was additive: no session files were edited. The persistent user-level config is `~/.codex/config.toml`; selectable profiles are `~/.codex/provider-*.config.toml`; role agents are `~/.codex/agents/provider-*.toml`; the no-secrets inventory is `~/.codex/provider-registry.json`.
Real command
node ~/.codex/scripts/codex-providers.mjs profiles
