passpass — perf claims allowed when ratio is green
Source: latest.csv:perf_present
Wall-clock row exists only — no explicit correctness signal yet.
- Ratio vs best competitor
- 1.000 (100.0% of cpp speed) (best in series:
cpp— Li is never labeled best) - Best competitor value
- 0.0005 s
Numeric oracle
No analytical verify rows in ingest yet. Run tier-1 with --verify so latest.csv exports verify_ulps / verify_within_1ulp.
