What changed in this PR
Addresses the arXiv researcher’s Codex startup failure by making its four inline agents inherit the workflow’s main model.
Changes:
- Removes explicit sub-agent model pins and refreshes the generated workflow metadata.
- Adds regression coverage for role generation without model overrides or resolution failures.

The arXiv researcher run failed before agent execution because Codex could not verify the configured sub-agent models against
