# MMA Tiered Architecture: Final Analysis Report

## 1. Executive Summary
The implementation and verification of the 4-Tier Hierarchical Multi-Model Architecture (MMA) within the Conductor framework have been successfully completed. The architecture provides a robust "Token Firewall" that prevents the primary context from being bloated by repetitive coding tasks and massive error traces.

## 2. Architectural Findings

### Centralized Strategy vs. Role-Based Sub-Agents
- **Decision:** A Hybrid Approach was implemented.
- **Rationale:** The Tier 2 Orchestrator (Conductor) maintains the high-level strategy via a centralized skill, while Tier 3 (Worker) and Tier 4 (QA) agents are governed by surgical, role-specific system prompts. This ensures that sub-agents remain focused and stateless without the overhead of complex, nested tool-usage logic.

### Delegation Efficacy
- **Tier 3 (Worker):** Successfully isolated code generation from the main conversation. The worker generates clean code/diffs that are then integrated by the Orchestrator.
- **Tier 4 (QA):** Demonstrated superior token efficiency by compressing multi-hundred-line stack traces into ~20-word actionable fixes.
- **Traceability:** The `-ShowContext` flag in `scripts/run_subagent.ps1` provides immediate visibility into the "Connective Tissue" of the hierarchy, allowing human supervisors to monitor the hand-offs.

## 3. Recommended Protocol (Final)

1. **Identification:** Tier 2 identifies a "Bloat Trigger" (Coding > 50 lines, Errors > 100 lines).
2. **Delegation:** Tier 2 spawns a sub-agent via `.\scripts
un_subagent.ps1 -Role [Worker|QA] -Prompt "..."`.
3. **Integration:** Tier 2 receives the stateless response and applies it to the project state.
4. **Checkpointing:** Tier 2 performs Phase-level checkpoints to "Wipe" trial-and-error memory and solidify the new state.

## 4. Verification Results
- **Automated Tests:** 100% Pass (4/4 tests in `tests/conductor/test_infrastructure.py`).
- **Isolation:** Confirmed via `test_subagent_isolation_live`.
- **Live Trace:** Manually verified and approved by the user (Tier 2 -> 3 -> 4 flow).

## 5. Conclusion
The MMA framework is now ready for production use within the Conductor environment. It significantly enhances the scalability of AI-driven development by protecting the most valuable resource: the Orchestrator's context window.
