Story 3.07 — MVFL Pipeline Integration Test Suite
Tests the full MVFL error-correction pipeline end-to-end.

Coverage:
  BB1:  Syntax error → CorrectionLoop runs → clean output returned on attempt 2
  BB2:  Qdrant scar match (high similarity) → VoyagerDefense blocks → CorrectionLoop runs
  BB3:  3-strike failure → MemGPTEscalation called
  BB4:  External rejection (status_code 422) → triggers external_rejection (severity 3)
  BB5:  Semantic inconsistency (status=completed + result=None) → triggers semantic (severity 2)
  BB6:  Clean output → no trigger, no correction, passes through unchanged
  BB7:  MVFLInterceptor post_execute → triggered output gets mvfl_corrected=True
  BB8:  MVFLInterceptor pre_execute → passes through unchanged (identity)

  WB9:  MVFLTrigger priority: external > semantic > syntax (both present → external wins)
  WB10: CorrectionLoop MAX_CORRECTION_ATTEMPTS constant = 3
  WB11: CorrectionLoop correction prompt always starts with "CORRECTION: "
  WB12: MemGPTEscalation uses ESCALATION_MODEL = "claude-opus-4-6"
  WB13: VoyagerDefense BLOCK_THRESHOLD default = 0.7
  WB14: OutputValidator collects ALL errors (not fail-fast)
  WB15: MVFLInterceptor priority = 90

  INT16: Full pipeline: trigger → voyager → correction → success on attempt 2
  INT17: Full pipeline: trigger → voyager → 3 failures → escalation → Opus result returned
