/**
 * Initiative Record — pure advisory Lifecycle gate evaluator (SPEC-004 Lifecycle Engine).
 *
 * TRANSCRIPTION, not design: transcribes the "gate evaluation" rules in
 * `.mma/specs/2026-08-13-spec-004-lifecycle-engine.md` (SPEC-004, FR-5, FR-6, FR-8) that
 * Task I-3 owns as its own dedicated Output. Task I-2 creates this module early — per its
 * own task context — because `sqlite-store.ts`'s `initiative_phase_satisfy` and
 * `initiative_focus_set` mutations must compute and record a `gate_snapshot` before Task
 * I-3 formally lands; the alternative (duplicating this logic inline in the store) is
 * explicitly disallowed. Task I-3 owns refining/extending this file and adding its own
 * dedicated test coverage and public barrel exports.
 *
 * This module performs NO database read or write, NO caching, and NO mutation of its
 * inputs. It is a pure function of already-read record data. The store
 * (`sqlite-store.ts`) is the only database owner and is the only caller — for both live
 * reads and required mutation snapshots.
