Test fixture for Check 43 — valid YES declaration.
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
# OST Render (fixture) This skill has valid frontmatter (YES) AND a `## Identifier exposure` body section. Check 43 should PASS. ## Identifier exposure **Declared**: YES Scope, rationale, anon-label convention, worked examples, and fixture pointer would live here in production.
Read the whole file at its exact version.
How to install
mdr add haabe/mycelium/ost-render@sha256:6d90b0912a237cb1The line at the top of this page pins the label git:20260607.772d097, 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.
