codex plugin not registered

[austere moss]

Many users report getting error messages to the effect "Codex plugin not registered".

This is caused by 5.12 hardcoding a dependency on @openclaw/codex but doesn't force install on update, only if the user is doing onboarding.

FIX:

openclaw plugins install @openclaw/codex@latest && openclaw gateway reload

Yep, that matches the 5.12 upgrade case: Codex can be required before @openclaw/codex has been installed locally.

Fix:
openclaw plugins install @openclaw/codex@latest && openclaw gateway reload

If the gateway still complains after that, restart it once and check openclaw --version so we’re not chasing a version mismatch.
