Trust receipt
Security, data integrity, citation quality, and advertised claims are measured separately from protocol uptime. Missing evidence is marked unverified, never converted into a pass.
| Dimension | Metric | Status | Evidence | Source |
|---|---|---|---|---|
| citation_quality | citation_capability_advertised | unverified | Metadata/tool descriptions advertise citation or evidence capability: set BEFORE moving anything and moves nothing at all if any Riddle is rejected, because Riddles that reference each other (a Quiz and the Leaderboard it reports to, a Form embedded in another Riddle) can only move together: not every Riddle riddle_move_check Checks, wit | Add items with questionBank_addItem, then reference the returned "id" as "questionBankId" on a QuestionBank block of a matching riddle_builder_quiz/riddle_builder_poll call - a bank created for "Quiz" can only b | Rejected with a QUESTION_BANK_INTERDEPENDENCY error if a Riddle in this bank's own project still references it, and DRAFTS COUNT: the reference tracking is refreshed on every write, whether that is a publish, a duplicate, a template-use, an edit in the Creator, or a. No response-level citation benchmark has verified this claim yet. | live_probe |
| security | sensitive_capabilities_declared | concern | 3 discovered tool(s) advertise potentially state-changing or privileged capabilities. Tool names: riddle_delete, questionBank_delete, questionBank_deleteItem. Classification is description-based and does not prove exploitability. Observed value: riddle_delete, questionBank_delete, questionBank_deleteItem Sample: n=3 | live_probe |
| security | authentication_boundary | observed | Live protocol probe observed auth_state=open. This describes discovery/access behavior; it is not by itself a vulnerability finding. Observed value: open | live_probe |
