Research direction

The check is in crates/registry-evidence/src/bundle.rs in the observe() function. Examine the logic that validates fixture case IDs against the expected categories. Update the error message to list which categories are missing. Also, find where fixture authoring is documented (likely in docs or a skills guide) and add the naming convention there. Run the existing tests for evidencectl test to verify the new error message is helpful.

Description

area:evidence bug documentation

What happens

evidencectl test refuses with fixture category coverage is incomplete unless the fixture file contains case ids that follow a naming convention (crates/registry-evidence/src/bundle.rs, observe()):

  • exactly positive, no-match, source-failure, anti-reconstruction;
  • ids starting with negative, boundary, missing, ambiguous;
  • a case with declaredUnresolved: true covers both no-match and ambiguous.

Why this is a problem

  • The convention is not documented in the Evidence authoring docs or skills (only anti-reconstruction is mentioned).
  • The error does not name the missing category. An author who named a case source-timeout instead of source-failure spent many iterations and concluded the check always fails.

Ask

Name the missing categories in the error, and document the id convention where fixtures are taught. Consider an explicit category: field instead of id prefixes.
