Test fixture for Check 43 — valid NONE 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, declared NONE)

This skill has valid frontmatter (NONE) AND a `## Identifier exposure` body section. Check 43 should PASS.

## Identifier exposure

**Declared**: NONE

Scope, rationale (no identifier fields touched), anon-label convention (n/a), worked example (zero-identifier render), and fixture-not-applicable note would live here in production.

How to install

The exact contents, by fingerprint
mdr add haabe/mycelium/ost-render@sha256:52b9c27dcf90e7de

The 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.
