📝 WalkthroughWalkthroughCodex now discovers models through the app-server, follows paginated catalogs, and merges live or static models with local configuration. The driver also mounts local and remote computer MCP integrations while forwarding credentials through child environments. ChangesCodex driver updates

Preserve the provider for locally injected bare model IDs.
mergeLocalInject adds custom options as { id: extra.id, custom: true }. A valid bare local ID now matches MODEL_ID and decodes as openai here. The selected local model can then override the configured local provider with the official provider.
Keep locally injected IDs provider-qualified, or make provider resolution depend on official-catalog membership. Add a regression test for a bare locally injected model ID.

What changed
codex app-server, including every pagination page.Why
OpenMausBot only exposed three hard-coded Codex models even though the installed CLI currently exposes seven. The Codex adapter also declared no computer MCP capability, so Local VM routing rejected Codex before a turn could start.
Impact
Codex users see the complete model list supported by their installed CLI and can use host/Local VM or remote computer tools like the other MCP-capable engines.
Validation
