Fuzzer Benchmark Report (from bug-count CSV)

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])

Throughput metrics (if supported by log format)
Values are run-level rates aggregated per fuzzer; n/a indicates the parser could not recover that metric from logs.

Progress metrics from logs (fuzzer-specific proxies)
Coverage/corpus values are parsed from each fuzzer's native progress output and are useful for trend context, not strict cross-fuzzer equivalence.
| Fuzzer | Runs | Seq/s runs | Seq/s p50 [p25,p75] | Coverage runs | Coverage p50 [p25,p75] | Corpus runs | Corpus p50 [p25,p75] |

Statistical comparison (Mann-Whitney U test)
Pairwise Mann-Whitney U tests on end-of-budget bug counts (two-sided). Bonferroni correction applied for 6 comparison(s). Significance level: alpha = 0.05.
Warnings:
- One or more fuzzers have fewer than 5 runs. Statistical power may be limited.
| Fuzzer A | Fuzzer B | Median A | Median B | U statistic | p-value | p (corrected) | Significant |
|---|---|---|---|---|---|---|---|
| echidna | medusa | 15.5 | 15 | 3.0 | 0.6171 | 1.0000 | no |
| echidna | recon-fuzzer | 15.5 | 15 | 3.0 | 0.6171 | 1.0000 | no |
| echidna | foundry | 15.5 | 13.5 | 4.0 | 0.3333 | 1.0000 | no |
| medusa | recon-fuzzer | 15 | 15 | 2.0 | 1.0000 | 1.0000 | no |
| medusa | foundry | 15 | 13.5 | 4.0 | 0.2207 | 1.0000 | no |
| recon-fuzzer | foundry | 15 | 13.5 | 4.0 | 0.2207 | 1.0000 | no |
No pairwise comparison reached significance after Bonferroni correction.
Note: The Mann-Whitney U test assesses whether one fuzzer tends to find more bugs than another across runs. It does not measure effect size or practical importance. Small sample sizes (fewer than 5 runs) reduce statistical power.
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.csvfor 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.
