"""decision_min_phase must cover every substantive decision type (data-driven via emits).

The reference bug: only the ~5 types referenced in prerequisites had a min phase; all
others (table_promoted, cte_approved, value_grounded, concept_formula_*, ...) defaulted
to phase 1, so require_phase_or_exit would accept them far too early. workflow.yaml now
declares `emits` per phase as the source of truth.
