TCC successfully authorizes com.openai.codex for kTCCServiceScreenCapture with authValue=2, result=true, and error=(null). Accessibility is already enabled for Codex Computer Use, and the CUA helper com.openai.sky.CUAService is running and correctly signed by OpenAI. However, Remote Control setup still returns "Couldn't check security requirements." This appears consistent with OpenAI Codex issue #36450, where Remote Control enrollment fails at the security-verification stage despite permissions being enabled.
