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: 0.973 (97.3% of cpp speed) (table SOTA: cpp — best competitor; charts use cpp = 1.0)
Best competitor value: 0.0036 s

No analytical verify rows in ingest yet. Run tier-1 with --verify so latest.csv exports verify_ulps / verify_within_1ulp.
