# Implementation Plan: Native Orchestrator (native_orchestrator_20260306)

> **Reference:** [Spec](./spec.md) | [Architecture Guide](../../../docs/guide_architecture.md)

## Phase 1: Plan File Operations
Focus: Native plan.md read/write

- [x] Task 1.1: Initialize MMA Environment (skipped - already in context)
- [x] Task 1.2: Implement read_plan function - COMMITTED: 1323d10
    - WHERE: `src/native_orchestrator.py`
    - WHAT: Parse plan.md content

- [x] Task 1.3: Implement write_plan function - COMMITTED: 1323d10

- [x] Task 1.4: Parse task checkboxes - COMMITTED: 1323d10

## Phase 2: Metadata Operations
Focus: Native metadata.json management

- [x] Task 2.1: Implement read_metadata - COMMITTED: 1323d10

- [x] Task 2.2: Implement write_metadata - COMMITTED: 1323d10

## Phase 3: In-Process Tier Delegation
Focus: Replace subprocess calls with direct function calls

- [x] Task 3.1: Create NativeOrchestrator class - COMMITTED: 1323d10
    - WHERE: `src/native_orchestrator.py` (new file)
    - WHAT: Class with tier methods (generate_tickets, execute_ticket, analyze_error, run_tier4_patch)

- [x] Task 3.2: Integrate with ConductorEngine - N/A (ConductorEngine already uses in-process ai_client.send())

## Phase 4: CLI Fallback
Focus: Maintain mma_exec.py compatibility

- [x] Task 4.1: SKIPPED - mma_exec.py is Meta-Tooling, not Application. NativeOrchestrator is for Application internal use.

## Phase 5: Testing
- [x] Task 5.1: Write unit tests - COMMITTED: 3f03663 (tests/test_native_orchestrator.py)
- [ ] Task 5.2: Conductor - Phase Verification
