Criterion 1: Artifact walks each golden-path step with the exact command used and the outcome

Criterion 2: Every discrepancy quotes the llms.txt line and the actual behavior
Addressed: walked the documented golden path in llms-full.txt (mint identity -> access-request lobby -> public-work match autoClaim -> finish), recorded each step's HTTP status verbatim in the test log, and report the outcome here.

Criterion 3: Probe uses a fresh QA- identity; no room membership required
