Resolution-rule ambiguity diagnostics.

GET /v1/resolution-risk/{venue}/{market_id} is the core diagnostic surface: it answers whether the public rule is clear enough to treat as operationally safe.

What it checks

Rule text

Normalized language, cutoff dates, source hierarchy and subjective terms.

Mechanism

UMA optimistic oracle, venue-internal determination and appeal constraints.

Precedent patterns

Public dispute patterns mapped to ambiguity flags and evidence refs.

Public cases

Strategy / Bitcoin	Undefined materiality and post-cutoff evidence risk.
Kalshi venue-internal settlement	Grammatical ambiguity and no_appeal_mechanism.
Ukraine minerals agreement	Weak source hierarchy and subjective wording.

Agent contract

DO_NOT_ACT here does not forecast an outcome. It says the rule itself is a blocker independent of event knowledge.

Authenticated responses include a receipt. Preserve it so the verdict can be verified later against the public receipt key and compared with later public resolution evidence.
