Nightly L4 regression failure

Commit: 4213cf8
Branch: develop
Workflow run: https://github.com/devonartis/agentauth/actions/runs/24299946253

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

Triage steps:

1. Download the regression-evidence-24299946253 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
