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])

Overall metrics

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 |

| echidna | 0.10h | inf | inf | 100.0% | 0.0% | 0.0% |
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.
| Fuzzer | Runs | Tx/s runs | Tx/s p50 [p25,p75] | Gas/s runs | Gas/s p50 [p25,p75] |
|---|---|---|---|---|---|

Progress metrics from logs (fuzzer-specific proxies)
Sequence-rate and corpus values are parsed from native progress output and are useful for within-tool trend context.
| Fuzzer | Runs | Seq/s runs | Seq/s p50 [p25,p75] | Corpus runs | Corpus p50 [p25,p75] |

Function selector sanity checks
Counts are occurrences in unique saved corpus sequences, not runtime execution frequencies The complete per-instance distribution is in selector_distribution.csv; selector_summary.json preserves statuses and provenance.
- Expected-set status: unavailable (0 selector(s))
- Expected-set provenance: peer-consensus heuristic: observed in every available corpus for at least two independent evidence families (Echidna and Recon count as one related typed-corpus family); not benchmark ground truth

Selector telemetry limitations
- No expected selector set was available: the peer heuristic requires corroboration from every available instance in at least two fuzzer families
Statistical comparison (Mann-Whitney U and Vargha-Delaney A12)
Pairwise Mann-Whitney U tests and Vargha-Delaney A12 effect sizes on end-of-budget bug counts. The tests are two-sided, with Bonferroni correction applied for 0 comparison(s). Significance level: alpha = 0.05.
Warnings:
- Only one fuzzer present; skipping pairwise statistical tests.
Note: A12 is the probability that a randomly selected Fuzzer A run has a higher final bug count than a randomly selected Fuzzer B run, counting ties as half. Values above 0.5 favor A, values below 0.5 favor B, and 0.5 means equal tendency. Magnitude thresholds by distance from 0.5 are negligible (<0.06), small (<0.14), medium (<0.21), and large (>=0.21). Small sample sizes (fewer than 5 runs) reduce statistical power. A12 and its magnitude label are descriptive; the thresholds are rules of thumb. Neither the effect size nor statistical significance establishes practical importance, causation, or performance beyond the observed runs.
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 count-based charts use normalized event identities stored under the legacy
bugs_foundcolumn. They do not count crash inputs, but they are not confirmed root-cause bug counts. - Use
known_bug_report.md,known_bug_summary.csv, andknown_bug_findings.csvfor evidence-backed known-bug hit rates; usebroken_invariants.md/broken_invariants.csvfor raw 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.

- Catalog:
benchmarks/known_bugs.json
Only the two instrumented health-check canaries are mapped. Other property failures remain unmapped until a reviewed root-cause record ties them to a confirmed bug.
Canaries are reported separately as harness-health checks and are never included in the known-bug hit-rate denominator.

Counting semantics
- A canonical known-bug ID counts at most once per replicate, even when several event aliases or counterexamples reach it.
- A replicate is identified by
(run_id, instance_id, fuzzer). - Known-bug hit rate is
canonical bug/replicate hits ÷ (cataloged bugs × replicates). - Unmapped rows are distinct normalized event identities per replicate. They are triage candidates, not claimed bugs.
- Crash inputs and corpus files are not used as bug identities.
