  HolyDiver / ENE - Mass Number Pre-Slots
  =========================================
  Pre-filled RealityContract templates for every major domain.
  Each "slot" is a contract stub with empty placeholder lists
  ready to be populated with domain-specific states/operators/
  observables/invariants/failures/boundaries.

  How to fill a slot:
    Replace `["..."]` with real entries, e.g.:
      validStates := ["definition", "theorem", "construction"]

  Slots are organized by MassKind and ComparisonLevel.
  Each slot includes handoffTargets suggesting cross-domain
  collaboration opportunities.
