PMI-WP-002StructuralTrack: Contract design & wordingRevised
Definition
Written to be quoted. This is the sentence to cite when a counterparty disagrees, not the sentence the tool shows you.
More than one fact is bundled into a single resolution, joined by “and” or “or”, with no stated rule for the case where the halves resolve differently. The contract has no defined outcome for a partial truth.
Remedy
Split it into separate questions, or state up front how a partial truth resolves.
Severity
Structural — likely to produce a disputed resolution
Where it comes from
What makes a question resolvable?
Ambiguity is the dominant failure mode in event markets. This track catalogues wording patterns that survive contested outcomes, and the ones that reliably produce disputes.

The identifier names the pattern for good. The version names the exact wording of the definition above, which is what an argument about a contract actually turns on.
