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
# Domain Error Strategy > **Layer 2: Design Choices** ## Core Question **Who needs to handle this error, and how should they recover?** Before designing error types: - Is this user-facing or internal? - Is recovery possible? - What context is needed for debugging? --- ## Error Categorization | Error Type | Audience | Recovery | Example | |------------|----------|----------|---------| | User-facing | End users | Guide action | `InvalidEmail`, `NotFound` | | Internal | Developers | Debug info | `DatabaseError`, `ParseError` | | System | Ops/SRE | Monitor/alert | `ConnectionTimeout`, `RateLimited` | | Transient | Automation | Retry | `NetworkError`, `ServiceUnavailable` | | Permanent | Human | Investigate | `ConfigInvalid`, `DataCorrupted` | --- ## Thinking Prompt Before designing error types: 1. **Who sees this error?** - End user → friendly message, actionable - Developer → detailed, debuggable - Ops → structured, alertable 2. **Can we recover?** - Transient → retry with backoff - Degradable → fallback value - Permanent → fail fast, alert 3. **What context is needed?** - Call chain → anyhow::Context - Request ID → structured logging …

How to install
mdr add moeru-ai/auv/m13-domain-error@sha256:8b20e875534e615dThe line at the top of this page pins the label git:20260725.8a8e541, 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.
