S Domain Modeling

Actively build and sharpen the project's domain model as you design. This is the active discipline: challenging terms, inventing edge-case scenarios, and writing the glossary and decisions down the moment they crystallise. (Merely reading CONTEXT.md for vocabulary is not this skill: that's a one-line habit any skill can do. This skill is for when you're changing the model, not just consuming it.)

Resolve apparent conflicts against accepted decisions and available evidence. Ask the person when consequential interpretations remain unresolved; keep pending interpretations out of accepted definitions. Use the project’s existing glossary and decision-record conventions; the formats below are defaults when none exist.
