v1.2.0 — Integration Harness Sealed

🔷 v1.2.0 — Integration Harness Sealed

This release locks the deterministic execution boundary of Adamantine Wallet OS with a fully sealed proof pack.

🔐 What This Version Guarantees

✅ Canonical Fixture Enforcement
• SHA256 computed over canonical JSON
• Whitespace / formatting independent hashing
• Manifest strictly enforces exact fixture set
• Hash mismatches fail CI immediately

✅ Integration Harness (E2E Determinism)
• Golden allow + deny fixtures
• Full orchestrator_v2 execution path exercised
• 50-run determinism tests (stable output across repeated runs)
• Stable response envelope shape enforced

✅ Contract Locking
• Response shape frozen:
• v
• request_id
• status
• decision
• reason_id
• artifacts
• No silent drift allowed

✅ EQC Threshold Enforcement
• Allow path verified
• Deny path verified via EQC_RISK_SCORE_BELOW_THRESHOLD
• Adapter-valid evidence bundles (Q-ID, Oracle v3, Shield v3)

✅ CI Integrity
• Strict manifest validation
• Deterministic fixture hashing
• ≥90% coverage maintained
• Fail-closed execution behavior

🧱 Architectural Impact

This release establishes:
• A reproducible execution boundary
• A sealed integration harness
• A stable foundation for:
• Shield layer freezing (v1.3.0)
• Adaptive Core oracle integration hardening
• Future policy pack governance
• Mobile platform integrations

⸻

Adamantine Wallet OS is no longer a prototype.

The execution contract is sealed.
