Nightly L4 regression failure

Commit: 899e4ca
Branch: develop
Workflow run: https://github.com/devonartis/agentwrit/actions/runs/24328255066

The nightly full regression suite failed. Evidence uploaded as workflow artifact.

Triage steps:

1. Download the regression-evidence-24328255066 artifact
2. Identify which batch failed (scripts/gates.sh regression output)
3. Reproduce locally: ./scripts/gates.sh regression
4. Open a fix branch if the failure is real, or close this issue if flaky
