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: 1.526 (152.6% of rust speed) (table SOTA: li — Li leads; charts use rust = 1.0)
Best competitor value: 0.0057 s

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