# CONTEXT.md — Domain Language > Create only when needed. Do not include implementation, status, scheduling, or decisions. ## Core Terms | Term | Precise definition | Evidence/source | |---|---|---| | `{term}` | `{what it means and how it differs from adjacent terms}` | `{business rule, contract, or code location}` | ## Concept Relationships - `{Concept A}` and `{Concept B}`: `{one-to-many / state transition / containment / constraint}`. ## Resolved Ambiguities - `{old expression}` now consistently means `{adopted interpretation}`; stop using `{deprecated expression}`. ## Needs Confirmation - `{term or relationship}`: awaiting confirmation from `{owner/domain role}`; do not change the implementation based on it until confirmed.
