Use when checking changes, staging files, pushing commits, or deciding whether production is live.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Validation

## Overview

Choose checks that prove the changed behavior without claiming more than they
prove.

## When to Use

Use before completion reports, commits, pushes, deployment checks, or live-status
claims.

## When NOT to Use

Do not run the full application suite for documentation-only changes.

## Core Process

1. Match checks to changed paths.
2. Run `git diff --check`.
3. Inspect `git status --short` and the diff; classify unrelated dirty files
   before staging.
4. For deletions, search manifest, import, timeline, and generated-data
   references before committing.
5. Stage explicit paths only.
6. For a feature-branch push, verify PR CI/preview for the feature SHA. For a
   production claim after squash merge, verify the deployment for the merged
   `upstream/main` SHA and smoke-test the affected route in Chromium.
7. For workflow edits, ensure dependency installation steps in credentialed workflows
   (`deploy.yml`, `preview.yml`, `update-content.yml`) use `npm ci` rather than
   `npm install` to guarantee byte-for-byte fidelity with `package-lock.json`.

How to install

The exact contents, by fingerprint
mdr add projectbluefin/website/validation@sha256:515d0c70fdd2e432

The line at the top of this page pins the label git:20261024.dfbf29b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
