chore(governance): Initialize Architect role and finalize handover

- Create skills/architect/SKILL.md and AUDIT_v0.2.md
- Update walkthrough.md with Governance section and Audit status
- Add .gitignore for project cleanliness

+# Architect Audit Report: ADD v0.2
+
+**Auditor:** @skills/architect  
+**Date:** 2025-12-23  
+**Document:** `docs/ADD_v0.2.md`  
+**Status:** APPROVED (Release v1.0)
+
+---
+
+## 1. Audit Summary
+
+The Architecture Definition Document v0.2 accurately reflects the v1.0 implementation.
+
+### Adherence Check
+
+| Component | ADD Spec | Implementation | Status |
+|-----------|----------|----------------|--------|
+| Bifurcated Execution | Camoufox → curl_cffi | `src/browser/manager.py`, `src/extractor/client.py` | ✅ |
+| Session Handover | Msgpack + HMAC | `src/core/session.py` | ✅ |
+| TLS Alignment | Chrome/120 → Chrome/124 | Updated in manager.py | ✅ |
+| GhostCursor | Bezier + Fitts's Law | `src/browser/ghost_cursor.py` | ✅ |
+| EntropyScheduler | Gaussian + Phase Drift | `src/core/scheduler.py` | ✅ |
+| ProxyRotator | Sticky Sessions | `src/core/proxy.py` | ✅ |
+| Monitoring | Prometheus Metrics | `src/core/monitoring.py` | ✅ |
+| Recovery | Session Invalidation | `src/core/recovery.py` | ✅ |
+
+### Minor Observations
+- TLS fingerprint was updated from `chrome120` to `chrome124` during Phase 3. ADD v0.2 still references `chrome120` in code examples. This is aesthetic, not functional.
+
+---
+
+## 2. Roadmap: ADD v0.3
+
+Based on Section 13 ("Future Enhancements") of the ADD:
+
+| Feature | Priority | Description |
+|---------|----------|-------------|
+| ML Behavior Generation | High | Train on real user sessions for mouse/scroll patterns. |
+| Adaptive Fingerprint Rotation | High | Rotate profiles based on challenge rate feedback. |
+| Distributed Orchestration | Medium | Deploy across multiple regions for geo-scaling. |
+| Computer Vision CAPTCHA | Low | Advanced image-based challenge solving. |
+
+---
+
+**Conclusion:** ADD v0.2 is architecturally sound and accurately documents v1.0.

+# Skill: Architect
+
+**Role:** Principal System Architect  
+**Status:** ACTIVE  
+**Version:** 1.0  
+
+## Mandate
+- Own the **Architecture Definition Document (ADD)**.
+- Ensure all implementations adhere to the **Bifurcated Execution Model**.
+- Guard system-wide design integrity across all phases.
+
+## Focus Areas
+- Core system abstractions and module boundaries.
+- Threat model evolution (behavioral biometrics, TLS fingerprinting, temporal analysis).
+- High-fidelity behavioral modeling (GhostCursor, EntropyScheduler).
+- Session handover protocol integrity.
+
+## Style
+- **Formal**: Precise language, rigorous definitions.
+- **Strategic**: Long-term vision, future-proofing.
+- **High-Level**: System-wide perspective, not implementation details.
+
+## Owned Artifacts
+- `docs/ADD_v0.1.md` (Archived)
+- `docs/ADD_v0.2.md` (Active - Released v1.0)
+
+## Responsibilities
+1. **Audit**: Review implementation against ADD specifications.
+2. **Evolve**: Maintain roadmap for future ADD versions.
+3. **Govern**: Approve significant architectural changes.
+
+## Roadmap (Future)
+- **v0.3**: ML-based behavior generation, adaptive proxy rotation.
+- **v0.4**: Distributed orchestration, global scaling.
