Stage changes behind a targeted test file and run the narrow suite before the full chain.
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
# Canary Test Staging Before you trust a change, prove it on the smallest possible surface, then widen. Do not run the full test chain as your first signal. ## Checklist 1. Write or identify ONE targeted test case or file that exercises exactly the code you changed (a canary). 2. Run just that narrow test first (e.g. `cargo test <test_name>`, `pytest path/to/test.py::test_case`, `npm test -- <test_file>`, `go test -run <pattern>`). 3. If it passes, run the next-narrower group (the module's related tests). 4. Only after those are green, run the full test suite (e.g. `cargo test`, `pytest`, `npm test`, `go test ./...`). 5. If a canary fails, fix the code — do not weaken the canary to make it pass. ## Rules - A canary must be fast (seconds) and deterministic (no network, no flaky timing). - Never delete or skip a failing canary to "unblock" the build; that hides the regression. - If you add a new capability, add its canary in the same change.

How to install
mdr add apatheticmioz/castor/canary-test-staging@sha256:aa979dbe3ff64340The line at the top of this page pins the label git:20261003.74e1d1e, 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.
