Milestone 5 (Cutover Health Auditor, TAC Bundler & Dual-Path Distribution Architecture): 12-point automated cutover verification playbook, pre/post snapshot diff engine (.standard / .zeroTolerance), 6-pattern SecretSanitizer (with EOS privilege/role matching), byte-exact POSIX ustar tarballing, RFC 1952 GZIP compression with table-driven CRC-32 & ISIZE validation, CryptoKit SHA-256 sidecar, eosTTY-AppStore.entitlements (App Sandbox) vs eosTTY-Direct.entitlements (Hardened Runtime).
6. Milestone 6 (100% E2E Verification & Adversarial Hardening): Full test suite pass across all 7 targets:
   • TerminalCoreTests: 40/40 passed
   • MetalRendererTests: 20/20 passed
   • KittyGraphicsTests: 40/40 passed
   • EAPIEngineTests: 39/39 passed
   • TelemetryVisualizerTests: 52/52 passed
   • CutoverAndTACTests: 77/77 passed
   • E2ETests: 320/320 passed (Tiers 1–5: Feature Coverage, Boundary & Corner, Cross-Feature Pairwise, Real-World Application Scenarios, Adversarial Hardening)
   • Total: 588 / 588 passed (100% pass rate, 0 failures).

Verification Evidence

• Build command: swift build --build-tests -Xswiftc -warnings-as-errors -> Clean exit 0 with 0 errors and 0 warnings.
• Test command: swift test -> 588 tests passed in 71.2s.
• Forensic Auditor verdict: CLEAN (0 facades, 0 hardcoded shortcuts, 0 skipped logic).
