Report ​

Fuzzer Benchmark Report (from bug-count CSV) ​

  • Time budget: 0.50h

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.

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.

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) ​

Sequence-rate and corpus values are parsed from native progress output and are useful for within-tool trend context.

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
  • i-0b7b9247f741264e6-foundry-git-02c05d9: Foundry selector distribution is unavailable because no persisted corpus was present; failure-event selectors are intentionally not used as a distribution

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:

  • One or more fuzzers have fewer than 5 runs. Statistical power may be limited.
  • Skipping recon-fuzzer vs foundry: fewer than 2 runs.

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_found column. They do not count crash inputs, but they are not confirmed root-cause bug counts.
  • Use known_bug_report.md, known_bug_summary.csv, and known_bug_findings.csv for evidence-backed known-bug hit rates; use broken_invariants.md / broken_invariants.csv for 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.

Broken invariants ​

  • Budget filter: 0.50h
  • Events considered: 16 / 16
  • Unique invariants: 11

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.

Ground-truth known-bug mapping ​

Ground-truth mapping was not applied.

  • Reason: run commit 3f1db8ad1a756bd3ac01e6575205913d35691479 is not the evidence-pinned catalog revision 459b020058f4a65d18eb1481083b75c766340124
  • Catalog: benchmarks/known_bugs.json

No event was classified as a known bug. Raw event analysis remains available, but it must not be interpreted as a confirmed bug count.
