Story 8.09: Integration Test Suite — Module 8 Dual-Loop
=========================================================

Validates the entire Module 8 (Evolution Dual-Loop) pipeline.
All 8 components must work together correctly.

Module 8 components:
  8.01  ImmutableKernel     — file permission locker
  8.02  AxiomaticTests      — compiled GLOBAL_GENESIS_RULES assertions
  8.03  MetaArchitect       — scar-driven structural analysis
  8.04  ShadowArena         — containerized test sandbox
  8.05  ScarAggregator      — L3 failure pattern collector
  8.06  CodeProposer        — structural fix generator
  8.07  GitOpsPRCreator     — GitHub PR automation
  8.08  Tier1AutonomousUpdater — epistemic self-updates

Integration test scenarios (IT1–IT10) + black box + white box cases.
Total: 20 test cases (exceeds the required 16).

ALL external services are mocked — no real Qdrant, Postgres, Redis,
GitHub, or git calls are made. File I/O uses pytest tmp_path only.
