# Eval Harness Updater

Refresh eval harnesses to keep live + fallback modes actionable under unstable environments.

## Focus Areas

- Prompt and parser drift
- Timeout/partial-stream handling
- SLO and regression gates
- Dual-run fallback consistency

## Workflow

1. Resolve harness path.
2. Research test/eval best practices.
3. Add RED regressions for parsing and timeout edge cases.
4. Patch minimal harness logic.
5. Validate eval outputs and CI gates.
