+## 5A. Fixture Rules
+
+When you touch `examples/`, keep the validation surface credible:
+
+- valid examples should be realistic, not cartoon placeholders
+- invalid examples should usually test one clear failure, not five at once
+- filenames should explain the scenario (`missing-input`, `invalid-version`, `extra-property`, etc.)
+- request examples must stay verb-aligned; do not copy an invalid fixture from one verb directory into another
+- valid receipts should use realistic `sha256:` digests and CID-shaped values
+
 Default assumption: **new version** for any semantic change.

-These commands compile schemas in strict Ajv mode and validate the shipped examples for both `v1.0.0` and `v1.1.0`.
+- `npm run validate` — the main contributor command. Compiles every schema, then validates every shipped example.
+- `npm run validate:schemas` — schema compilation only. Useful when changing schema files or Ajv configuration.
+- `npm run validate:examples` — fixture pass/fail verification only. Useful when editing examples or improving failure coverage.
+
+For `v1.1.0`, fixture discipline matters as much as schema compilation: valid examples must look operationally plausible, and invalid examples should usually fail for one clear reason that matches the filename.
 
 ---
 
+## Fixture discipline
+
+For `examples/v1.1.0/commons/`, contributors should treat fixtures as protocol evidence, not filler:
+
+- valid examples should look realistic enough that an implementer could model against them
+- invalid examples should usually exercise one clear failure mode
+- filenames should describe the exact failure being tested
+- request fixtures must stay aligned with the verb directory they live in; deliberate wrong-verb cases must be explicitly named
+- valid receipts should use realistic digest and CID-shaped values instead of toy placeholders
