- Add nullish coalescing on fix.findings ?? [] so absent findings
array in a fixture is represented as zero Findings [] for the A/B
input apparatus.
- Append product-launch second controlled case (live-product-launch-
start-response.json) with zero Findings to the epistemic comparison
test suite. All 34 tests pass deterministically.
- Update docs/current-handoff.md to record the zero-Findings case.
