Pull request overview
Updates the Daily Go Test Parallelizer workflow to restore safe-output generation.
Changes:
- Switches the configured Codex model.
- Restores the default Docker sandbox.
- Regenerates the compiled workflow.
The replacement model remains unsupported by Codex 0.150.1 and fails the existing contract test. Use a recognized/default model, update the test, and regenerate the lock file.

The Daily Go Test Parallelizer workflow completed without generating any safe outputs, triggering an automated failure issue flagged with
model_not_supported_errorandmissing_safe_outputs.Root causes identified from job logs
model: copilot/gpt-5.3-codexis not recognized by the Codex CLI's model metadata registry (Unknown model openai/gpt-5.3-codex is used), which matches gh-aw's failure detector regex for unsupported models.sandbox.agent.runtime: cloud-hypervisor(a preview KVM microVM sandbox) intermittently lacked basic coreutils —grep,find, andsortall reported "command not found" in the sandboxed environment, even in a run that otherwise completed. This broke the workflow's file-selection step, which relies ongrepto enumerate candidate test files.Changes
