Prediction market insider trading concentrates in three principal types — government officials with policy information, ICO teams with operational information, and candidates with electoral information — each requiring different enforcement mechanisms

## Criterion-by-Criterion Review **1. Schema:** All three new/modified claims have complete frontmatter with type, domain, confidence, source, created, and description fields; the entity files (mark-moran.md, matt-klein.md, ezekiel-enriquez.md) are not shown in the diff but their filenames follow entity conventions; the inbox source file has a different schema as expected. **2. Duplicate/redundancy:** The new "adversarial self-testing" claim introduces genuinely novel analysis (deliberate rule violations as PR strategy) distinct from the "three principal types" claim (which categorizes insider types), and the enrichments to existing claims add new evidence (Kalshi enforcement actions) rather than repeating what's already present. **3. Confidence:** All three claims use "experimental" confidence, which is appropriate given they're drawing novel theoretical frameworks (adversarial self-testing threat model, three-category typology) from a single enforcement event in April 2026 with limited historical precedent. **4. Wiki links:** The "three principal types" claim includes related links to other claims that may or may not exist in the current knowledge base, but as instructed, broken links are expected and do not affect the verdict. **5. Source quality:** Kalshi's public enforcement announcements are primary source documents directly from the platform conducting the enforcement actions, making them highly credible for claims about those specific cases and their enforcement patterns. **6. Specificity:** Each claim makes falsifiable assertions—someone could disagree that adversarial self-testing constitutes a "distinct threat model," that three categories exhaust the typology, or that enforcement timing was strategically chosen for regulatory signaling—making them appropriately specific rather than vague. **Factual accuracy check:** The claims accurately represent that Kalshi imposed differentiated penalties (Moran: $6,229 + 5-year suspension vs Klein: $540, Enriquez: $784), that Moran publicly stated intent to expose enforcement gaps and proposed a "vice tax," and that these cases document candidates betting on their own races—all verifiable from the source material. <!-- VERDICT:LEO:APPROVE -->
