PR Summary

Removes the Codex.app pin from the macOS Dock managed by nix-darwin so it no longer appears after a darwin-rebuild switch. The Codex CLI tooling elsewhere in the repo (config/codex/, fish _coxe* helpers, cliproxyapi keychain sync) is untouched — this only affects the Dock icon.

• Delete "/Applications/Codex.app" entry from system.defaults.dock.persistent-apps in nix-darwin/config/dock.nix.

I’m a bunny by the Dock today,
Watching Codex hop away.
ChatGPT and Claude remain,
In a tidy carrot lane.
Nix makes order, neat and bright!

Mesa Description

TL;DR

Removed Codex.app from the list of persistent applications in the macOS Dock configuration.

What changed?

• nix-darwin/config/dock.nix: Removed /Applications/Codex.app from the persistent applications list.

Performed full review of 1929b38...3b618b8

Analysis

• Incomplete deprecation signal: Removing Codex from Dock while leaving CLI infrastructure (config/codex/, fish helpers, keychain sync) intact creates ambiguity about intent—clarify whether this is a UX preference adjustment or step 1 of full deprecation to prevent future confusion.

• Configuration drift risk: Documentation, onboarding materials, or screenshots may reference Codex in the Dock and become stale; verify and update collateral as needed.

• Undocumented coupling assumption: The change assumes persistent-apps is purely presentational; if Dock entries imply "approved/required apps" elsewhere, this hidden coupling should be explicitly documented to prevent misinterpretation.
