Paid local software$99 USD

Run-input gate / v1.0.0

Replay Input Preflight

Stop a replay when a required local file is missing, changed, outside its declared set, or over the byte limit—without running it.

Supported decisionDo the declared local files pass the exact checks required before this replay starts?

Inputs, delivery, limits & evidence
Best for
Independent researchers and small data, ML, or automation teams that need a standalone local gate
Input
Strict JSON contract plus contained local files and directories
Output
READY, REVIEW, or BLOCKED pack with JSON, Markdown, and checksums
Delivery
Private Python 3.11+ package; no account to run, replay execution, upload, telemetry, or runtime network

Stops at: declared presence, identity, discovery, and byte checks—not semantics, independence, completeness, reproducibility, safety, or fitness.

Evaluation & contracts
Paid review$450 USD

Repository-specific / human analysis

Release Boundary Review

Find the gap between checks that ran and a release decision you can actually explain.

Supported decisionWhere is one public repository’s named release path still relying on implicit evidence, identity, admission, or attempt boundaries?

View review Request the $450 review
Inputs, delivery, limits & evidence
Best for
Maintainers and small engineering teams preparing a release
Input
One public GitHub repository and one named release workflow
Output
Decision map, gap assessment, and prioritized implementation roadmap
Delivery
Within five business days after accepted intake and payment

Stops at: architecture review—not implementation, security testing, compliance, or release assurance.

Evaluation & contracts
Paid local software$499 USD

Temporal data boundaries / v1.1.0

Temporal Boundary Auditor

Check whether a historical join used data that arrived too late, came from an unfinished period, was stale, duplicated a time key, or may be using the wrong clock.

Supported decisionWas each selected historical row available by decision time—and do the declared clocks, periods, grids, duplicates, and freshness limits hold?

View product Request the $499 tool
Inputs, delivery, limits & evidence
Best for
Data and ML engineers, quantitative researchers, and pipeline reviewers
Input
Strict JSON contract plus contained local CSV or JSON Lines files
Output
Deterministic audit or clock-probe JSON, JSON Lines, and Markdown
Delivery
Private Python 3.11+ package; no account to run, upload, telemetry, or runtime network requests

Stops at: mechanical checks—not true-clock proof, causality, complete lineage, compliance, or fitness.

Evaluation & contracts
Paid local software$249 USD

Model input governance / v1.0.0

Target-Blind Feature Freezer

Freeze a deterministic candidate-feature contract from values-free schema metadata before target values are read.

Supported decisionCan candidate features be fixed from declared roles, types, and policy before outcome knowledge can influence the list?

View product Request the $249 tool
Inputs, delivery, limits & evidence
Best for
ML engineers, data scientists, validators, and governance teams
Input
Strict policy contract plus values-free JSON column schema
Output
Ordered manifest, selected/excluded ledgers, summary, and checksums
Delivery
Private Python 3.11+ package; no account to run, upload, telemetry, or runtime network requests

Stops at: declared schema discipline—not upstream-computation proof, hidden-proxy detection, model validity, or fitness.

Free MIT utility$0

Evidence and review / v1.3.2

Evidence Preflight

Turn a persuasive claim into an inspectable evidence record before review, publication, or operational use.

Supported decisionIs the claim’s scope, provenance, comparison, failure criteria, limitations, and intended use documented well enough for serious review?

View product Open worksheet
Inputs, delivery, limits & evidence
Best for
Researchers, technical operators, reviewers, and evidence-producing teams
Input
A claim and the supporting record you want reviewers to inspect
Output
Markdown or schema-identified JSON evidence card
Delivery
Browser-local worksheet plus dependency-free Node.js validator

Stops at: documentation completeness—not truth, causality, statistical validity, or decision fitness.

Free MIT utility$0

Artifact governance / v0.1.1

Artifact Admission

Turn exact artifact evidence and a declared lifecycle policy into an explicit local admit-or-deny decision.

Supported decisionMay this exact implementation artifact advance under the declared subject, evidence, freshness, receipt, and verifier policy?

View product Download package
Inputs, delivery, limits & evidence
Best for
Platform and release engineers, governed repositories, CI, and agents
Input
Policy, exact artifact/evidence files, and one lifecycle receipt
Output
Schema-identified JSON admission decision with selected receipt hash
Delivery
Dependency-free Node.js 20+ library and CLI

Stops at: local policy consistency—not signatures, provenance attestation, vulnerability scanning, safety, or fitness.

Free MIT utility$0

Execution governance / v0.1.0

Attempt Boundary

Distinguish a preflight failure from the point where a costly or stateful execution attempt was actually invoked.

Supported decisionDid preflight prevent execution, or did the real command cross the attempt boundary and conservatively consume retry lineage?

View product Download package
Inputs, delivery, limits & evidence
Best for
Automation operators, research engineers, CI systems, and agents
Input
Reviewed plan, workspace, commands, limits, and protected paths
Output
Create-only schema-identified JSON attempt receipt
Delivery
Dependency-free Node.js 20+ library and CLI

Stops at: observed wrapper lineage—not sandboxing, proof of non-access, host integrity, safety, or correctness.

Evaluate before choosing

Descriptions route attention. Exact public records support evaluation.

The Evidence Library separates current paid-product evaluation packs, withdrawn product records, the fictional review sample, and complete narrow MIT utilities—with hashes and non-claims beside the artifacts. Tabular Shape Receipt and Local Input Receipt remain inspectable but accept no new orders.
