- [Screenshot Redaction Proof Studio](https://fasttool.app/tools/screenshot-redaction-proof-studio/): Redact selected screenshot regions with solid fills, re-encode a metadata-free PNG, verify output pixels and export a reviewable proof packet.
- [ML Dataset Leakage & Drift Lab](https://fasttool.app/tools/ml-dataset-leakage-drift-lab/): Compare train and test CSV splits for copied or near-duplicate rows, entity and time leakage, target proxies and feature drift before release.

## Other reviewed workflows
- [Audio Cutter Online](https://fasttool.app/tools/audio-cutter/): Trim a browser-decodable audio file to an exact range and leave with a locally verified PCM WAV plus hash-backed JSON and Markdown receipts.
- [Receipt Verifier](https://fasttool.app/tools/receipt-verifier/): Recompute a FastTool Receipt v1 core hash and compare optional local artifact bytes with declared hashes so reviewers can distinguish intact, broken and incomplete evidence packets.

- Tool inputs are not included in analytics. Advertising remains disabled during review.

# ToolContract detail

## Audio Cutter Online
- Canonical: https://fasttool.app/tools/audio-cutter/
- Job: Trim a browser-decodable audio file to an exact range and leave with a locally verified PCM WAV plus hash-backed JSON and Markdown receipts.
- Inputs: local_audio_file, synthetic_wav_fixture, numeric_time_range
- Artifacts: verified-pcm16.wav, audio-cutter-receipt.json, audio-cutter-receipt.md
- Limits: Output is 16-bit PCM WAV only; the tool does not preserve the source codec or container.; Input is capped at 200 MiB and output at 100 MiB so the public Receipt Verifier can compare the exact artifact bytes within its bounded local verification limit.; The receipt proves artifact-byte integrity for this run, not rights ownership, mastering quality, authorship, or forensic authenticity.
- Ad state: off_during_review

## DMARC Report Triage
- Canonical: https://fasttool.app/tools/dmarc-report-triage/
- Job: Triage batches of DMARC aggregate reports into deduplicated sender evidence, alignment trends, classification gaps and a remediation packet.
- Inputs: safe_sample, multiple_xml_files, multiple_xml_gzip_files, zip_archives, local_source_classification
- Artifacts: dmarc-source-summary.csv, dmarc-trend.svg, dmarc-remediation.md, receipt.json, dmarc-report-triage-proof-pack.zip
- Limits: At most 100 report files, 10 MiB compressed and 5 MiB expanded per file, 25 MiB expanded per batch and 250000 record rows.; The tool parses aggregate reports but does not change DNS, send mail, inspect message content or guarantee deliverability.; Source IP addresses and authentication identifiers can be sensitive and should be handled only on a trusted device.
- Ad state: off_during_review

## ML Dataset Leakage & Drift Lab
- Canonical: https://fasttool.app/tools/ml-dataset-leakage-drift-lab/
- Job: Compare train and test CSV splits for copied or near-duplicate rows, entity and time leakage, target proxies and feature drift before release.
- Inputs: safe_sample, random_synthetic_case, train_csv, test_csv, split_policy
- Artifacts: ml-dataset-leakage-drift-lab-evidence.svg, ml-dataset-leakage-drift-lab-overlap-ledger.csv, ml-dataset-leakage-drift-lab-feature-drift.csv, ml-dataset-leakage-drift-lab-quarantine.csv, ml-dataset-leakage-drift-lab-remediation.md, ml-dataset-leakage-drift-lab-receipt.json
- Limits: Each split is capped at 1000 rows and 60 columns; pairwise near-duplicate scanning is explicitly bounded.; Drift metrics do not prove model performance harm and correlation or association does not establish causality.; Use only public, synthetic or fully de-identified rows; sensitive row-level data is outside the privacy boundary.
- Ad state: off_during_review

## Receipt Verifier
- Canonical: https://fasttool.app/tools/receipt-verifier/
- Job: Recompute a FastTool Receipt v1 core hash and compare optional local artifact bytes with declared hashes so reviewers can distinguish intact, broken and incomplete evidence packets.
- Inputs: receipt_json_paste, receipt_json_file, optional_artifact_files, optional_parent_receipt_files, generated_safe_fixture
- Artifacts: fasttool-receipt-verification.json, fasttool-receipt-verification.md
- Limits: Integrity PASS does not establish authorship, source authenticity, factual correctness or independent certification.; Engine hashes are reported but executable engine bytes are not accepted or executed.; Parent links PASS only when every declared parent and transitive ancestor receipt core is supplied and recomputed; parent artifact bytes are not checked by the chain result.
- Ad state: off_during_review

## SARIF Finding Delta & Release Gate
- Canonical: https://fasttool.app/tools/sarif-finding-delta-release-gate/
- Job: Validate baseline and candidate SARIF 2.1.0 reports, compute fingerprint-aware finding deltas and produce an explicit evidence-backed release gate.
- Inputs: safe_sample, baseline_sarif_json, candidate_sarif_json, local_sarif_files, release_policy
- Artifacts: sarif-finding-delta.json, sarif-finding-delta.csv, sarif-release-gate.md, sarif-release-gate.svg, sarif-release-gate-policy.json, sarif-release-gate-annotations.sarif, sarif-release-gate-receipt.json
- Limits: The tool validates supported self-contained SARIF but does not scan code, resolve external property files or deploy a release.; A PASS is a policy result for the supplied reports, not proof that software is secure or free of unreported findings.; Each input is capped at 5 MiB, 100 runs, 50000 results, 600000 JSON nodes and 96 nesting levels.
- Ad state: off_during_review

## Screenshot Redaction Proof Studio
- Canonical: https://fasttool.app/tools/screenshot-redaction-proof-studio/
- Job: Redact selected screenshot regions with solid fills, re-encode a metadata-free PNG, verify output pixels and export a reviewable proof packet.
- Inputs: safe_sample, local_image_file, clipboard_image, manual_redaction_regions
- Artifacts: redacted-screenshot.png, redaction-zones.json, redaction-map.svg, redaction-audit.csv, share-safety-manifest.md, screenshot-redaction-proof-receipt.json
- Limits: Input is capped at 25 MiB, 8 megapixels, 64 redaction zones and 16 million total zone-check pixels.; OCR is intentionally disabled; the tool cannot discover unselected sensitive text or certify legal redaction.; Receipts bind the local input and artifacts but do not prove an external share, deletion or recipient state.
- Ad state: off_during_review

## Spreadsheet Formula & Hidden-Link Forensics Lab
- Canonical: https://fasttool.app/tools/spreadsheet-formula-hidden-link-forensics-lab/
- Job: Review an XLSX workbook for formulas, hidden structures, external relationships and formula changes before trusting or releasing it.
