Validity gate

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: 0.751 (75.1% of rust speed) (best in series: rust — Li is never labeled best)
Best competitor value: 2.5908 s

Numeric oracle

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

Problem size: algo registry stub
Category: physics
Pillar: physics
Package: lic
Li / catalog oracle (mean ± σ): 3.4496 s / 2.647 s (cpp)
Ratio vs catalog oracle: 1.3032×
Best competitor: rust (2.5908 s)
Li relative speed vs SOTA: 0.751 (1.0 = rust speed)
Validity: validity pass
Threshold: 1.2×

Performance vs best competitor

Compare oracle: cpp

Relative speed vs best competitor (rust) — SOTA = 1.0, higher is better. Absolute s values are in the table below.Validity gate not passed — bars are informational only.
