Make interfaces perceivable, operable, understandable, and robust. Use when planning or reviewing accessibility; do not use as provider-specific implementation guidance.
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.

# Accessibility
## Purpose
Make interfaces perceivable, operable, understandable, and robust.
## Problem Statement
Without a shared decision model, accessibility is often driven by habit or defaults, producing inconsistent boundaries and hidden trade-offs.
## When to Use
Use when requirements, architecture, reviews, or change plans require decisions about accessibility, before implementation choices become expensive to reverse.
## When NOT to Use
Do not substitute it for product requirements, provider documentation, implementation instructions, or accountable Agent decisions.
## Core Concepts
- Scope and accountable ownership.
- Inputs, outputs, invariants, and failure contracts.
- Evidence from requirements, measurements, risks, and consumers.
- Compatibility, migration, and rollback.
- Verification and review criteria.
## Engineering Principles
- Start from explicit outcomes and constraints.
- Keep boundaries visible.
- Prefer evidence over defaults.
- Make failure and change consequences reviewable.
- Choose the simplest adequate approach.
## Decision Tree
1. Clarify outcome and owner.
2. Record hard constraints and invariants.

The line at the top of this page pins the label git:20260804.bc7d3a4, 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.
