Fuzzer Benchmark Report (from bug-count CSV)
- Time budget: 2.00h
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.
⚠️ Run health
The following fuzzer legs show signs of not having run for the full time budget. Their results below are not comparable to healthy legs.
- ⚠️ foundry: no bugs and no runtime activity samples were parsed from any instance — the fuzzer most likely never executed (startup/compile failure). Inspect the instance bootstrap logs before drawing conclusions from this leg.
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 |
|---|---|---|
| foundry | 4 | 0 [0,0] |
Overall metrics
| Fuzzer | AUC (norm) | Plateau time | Late discovery share | Final median | Final IQR |
|---|---|---|---|---|---|
| foundry | 0.000 | 0.00h | 0.000 | 0 | 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 | inf | inf | inf | 0.0% | 0.0% | 0.0% |
Statistical comparison (Mann-Whitney U test)
Pairwise Mann-Whitney U tests on end-of-budget bug counts (two-sided). Bonferroni correction applied for 0 comparison(s). Significance level: alpha = 0.05.
Warnings:
- Only one fuzzer present; skipping pairwise statistical tests.
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.
