+# Specification: MMA Tiered Architecture Verification
+
+## Overview
+This track aims to review and verify the implementation of the 4-Tier Hierarchical Multi-Model Architecture (MMA) within the Conductor framework. It will confirm that Conductor operates as a Tier 2 Tech Lead/Orchestrator and can successfully delegate tasks to Tier 3 (Workers) and Tier 4 (QA/Utility) sub-agents. A key part of this track is investigating whether this hierarchy should be enforced via a single centralized skill or through separate role-based sub-agent definitions.
+
+## Functional Requirements
+1. **Skill Review:** Analyze `mma-orchestrator/SKILL.md` and `MMA_Support` docs to ensure they correctly mandate Tier 2 behavior for Conductor.
+2. **Delegation Verification:**
+   - Verify Conductor (Tier 2) can spawn Tier 3 sub-agents for heavy coding tasks using `.\scripts
+un_subagent.ps1`.
+   - Verify Tier 3/4 sub-agents can be spawned for error analysis/compression.
+3. **Architectural Investigation:** Evaluate the pros/cons of a centralized `mma-orchestrator` skill vs. independent role-based sub-agents. Determine the best way to define sub-agent roles.
+4. **Test Track Creation:** Implement a "Mock Implementation" track that demonstrates the full tiered delegation flow (Tier 2 -> Tier 3 -> Tier 4).
+5. **Automated Testing:** Create `pytest` cases to verify the IPC and script execution flow of the tiered sub-agents.
+
+## Non-Functional Requirements
+- **Traceability:** All sub-agent invocations must be clearly logged in the session.
+- **Context Efficiency:** Ensure sub-agent delegation effectively prevents token bloat in the main Conductor context.
+
+## Acceptance Criteria
+- [ ] Analysis report comparing centralized skill vs. role-based sub-agents.
+- [ ] A functional test track (`mma_verification_mock`) that executes a full tiered delegation sequence.
+- [ ] Traceable logs confirming sub-agent spawning and task completion.
+- [ ] Pytest suite verifying the sub-agent infrastructure and interaction logic.
+- [ ] Plan alignment: The test track's `plan.md` explicitly includes delegation steps.
+
+## Out of Scope
+- Implementing a full production-ready multi-model backend.
