/*
<MODULE_CONTRACT>
<purpose>
  RFC-1263: shared lifecycle coverage predicate for mission.reconcile and
  mission.close. A mission may reconcile or close when EITHER the stored
  full-validation report is green OR the mission record carries a green
  fast-lane gate set (mission.content-edit). Both commands consult this one
  predicate — no per-command re-derivation.
</purpose>
<non-goals>
  <item>Do not weaken leitstand.ship — ship still runs full mission.validate
  before deploy phases; the fast lane only relaxes the pre-ship lifecycle
  precondition.</item>
  <item>Do not synthesize a validation report — fast-lane evidence lives in
  the mission manifest under fastLane; validation-report.json is only ever
  written by a real mission.validate run.</item>
</non-goals>
</MODULE_CONTRACT>
<CHANGE_SUMMARY>
  <item>RFC-1263: initial predicate — contractFull.passed || fastLane.green.</item>
