// Step 1877: Sprint 269 integration summary
//
// Verifies that all Sprint 269 new components compile and interoperate
// correctly in a combined scenario:
//
//  t1: RequirementsParser prose capture + GateEnforcer → prose spec feeds into gated review
//  t2: CrossArtifactConsistencyEngine detects drift and GateEnforcer blocks production
//  t3: ParitySkewAnalyzer + CrossArtifactConsistencyEngine → multi-signal quality check
//  t4: GateEnforcer with mixed gates (security fail + performance fail) → only security blocks
//  t5: Full pipeline: prose intake → consistency check → gate enforcement (no drift → not blocked)
