Run 1771869505

• Date (UTC): 2026-02-23 17:58:25Z
• Benchmark: 4bd654eeed89258fdff40ed9f9954726
• Timeout: 4h

Trial run

Warning — trial run. This benchmark was executed with fewer than 10 instances per fuzzer and/or a time budget shorter than 24h. Results from trial runs are meant for debugging purposes and are not valid for extracting conclusions across different fuzzers.

Report

Fuzzer Benchmark Report (from bug-count CSV)

• Time budget: 4.00h

Executive summary

This report is derived solely from cumulative bugs-found over time across repeated runs per fuzzer. It emphasizes robust, distribution-based metrics (median/IQR, success rates, time-to-k) and shape-based behavior (plateau time, late discovery share) instead of single-run time-to-first-bug.

Bugs found at fixed time budgets (median [IQR])

Fuzzer	Runs	1h	4h
foundry	2	6 [6,6]	6 [6,6]
medusa	2	6 [6,6]	6 [6,7]
echidna	2	4 [4,4]	5 [5,5]

Overall metrics

Fuzzer	AUC (norm)	Plateau time	Late discovery share	Final median	Final IQR
foundry	0.854	0.10h	0.000	6	0.00
medusa	0.845	2.30h	0.077	6	0.50
echidna	0.598	3.80h	0.100	5	0.00

Milestones: time-to-k and success rates

Fuzzer	time-to-1 (p50)	time-to-3 (p50)	time-to-5 (p50)	reach-1 rate	reach-3 rate	reach-5 rate
foundry	0.00h	0.00h	0.00h	100.0%	100.0%	100.0%
medusa	0.10h	0.10h	0.40h	100.0%	100.0%	100.0%
echidna	0.10h	0.10h	2.85h	100.0%	100.0%	100.0%

Shape-based interpretation (rules of thumb)

• Fast-start / early-plateau: high early checkpoint median + early plateau time + low late discovery share.
• Steady: moderate AUC, later plateau, consistent improvements across checkpoints, moderate variance.
• Slow-burn / late-surge: low early checkpoints but high late discovery share and later plateau time; often higher final median.

Limitations

• Core metrics in this section are count-based; use broken_invariants.md / broken_invariants.csv for invariant identities.
• Severity, exploitability, and root-cause uniqueness cannot be measured directly without richer per-bug metadata.
• Harness design still affects results; mitigate by keeping harness identical across fuzzers and reporting many runs.
