+
+## Architecture Fallback
+When planning tracks that touch core systems, consult the deep-dive docs:
+- `docs/guide_architecture.md`: Thread domains, event system, AI client, HITL mechanism, frame-sync action catalog
+- `docs/guide_tools.md`: MCP Bridge security, 26-tool inventory, Hook API endpoints, ApiHookClient
+- `docs/guide_mma.md`: Ticket/Track data structures, DAG engine, ConductorEngine, worker lifecycle
+- `docs/guide_simulations.md`: live_gui fixture, Puppeteer pattern, mock provider, verification patterns
+
+## The Surgical Methodology
+
+When creating or refining tracks, you MUST follow this protocol:
+
+### 1. MANDATORY: Audit Before Specifying
+NEVER write a spec without first reading the actual code using your tools.
+Use `get_code_outline`, `py_get_definition`, `grep_search`, and `get_git_diff`
+to build a map of what exists. Document existing implementations with file:line
+references in a "Current State Audit" section in the spec.
+
+**WHY**: Previous track specs asked to implement features that already existed
+(Track Browser, DAG tree, approval dialogs) because no code audit was done first.
+This wastes entire implementation phases.
+
+### 2. Identify Gaps, Not Features
+Frame requirements around what's MISSING relative to what exists:
+GOOD: "The existing `_render_mma_dashboard` (gui_2.py:2633-2724) has a token
+usage table but no cost estimation column."
+BAD: "Build a metrics dashboard with token and cost tracking."
+
+### 3. Write Worker-Ready Tasks
+Each plan task must be executable by a Tier 3 worker on gemini-2.5-flash-lite
+without understanding the overall architecture. Every task specifies:
+- **WHERE**: Exact file and line range (`gui_2.py:2700-2701`)
+- **WHAT**: The specific change (add function, modify dict, extend table)
+- **HOW**: Which API calls or patterns (`imgui.progress_bar(...)`, `imgui.collapsing_header(...)`)
+- **SAFETY**: Thread-safety constraints if cross-thread data is involved
+
+### 4. For Bug Fix Tracks: Root Cause Analysis
+Don't write "investigate and fix." Read the code, trace the data flow, list
+specific root cause candidates with code-level reasoning.
+
+### 5. Reference Architecture Docs
+Link to relevant `docs/guide_*.md` sections in every spec so implementing
+agents have a fallback for threading, data flow, or module interactions.
+
+### 6. Map Dependencies Between Tracks
+State execution order and blockers explicitly in metadata.json and spec.
+
+## Spec Template (REQUIRED sections)
+```
+# Track Specification: {Title}
+
+## Overview
+## Current State Audit (as of {commit_sha})
+### Already Implemented (DO NOT re-implement)
+### Gaps to Fill (This Track's Scope)
+## Goals
+## Functional Requirements
+## Non-Functional Requirements
+## Architecture Reference
+## Out of Scope
+```
+
+## Plan Template (REQUIRED format)
+```
+## Phase N: {Name}
+Focus: {One-sentence scope}
+
+- [ ] Task N.1: {Surgical description with file:line refs and API calls}
+- [ ] Task N.2: ...
+- [ ] Task N.N: Write tests for Phase N changes
+- [ ] Task N.X: Conductor - User Manual Verification (Protocol in workflow.md)
