# WEB015-LAB1 — Astro boundary evidence fixture

This learner fixture tests the reasoning contract offline. It includes Astro-shaped source files plus a dependency-free deterministic emitted-output model. The public acceptance run **does not claim** that Astro itself was installed, built, previewed, or observed in a browser.

Run:

```bash
node --test test/public-contract.test.mjs
node src/inspect-boundary.mjs
```

Then complete `evidence/Astro_Rendering_Island_Boundary_Record_v1.json`, run the mutations described in the lesson, repair the plan, and complete the product-catalog transfer.

When a publisher runtime with pinned Astro and adapter packages is available, extend the evidence with a real build and preview. Do not rewrite deterministic model output as real Astro observation.
