# Track Specification: Robust Live Simulation Verification

## Overview
Establish a robust, visual simulation framework to prevent regressions in the complex GUI and asynchronous orchestration layers. This track replaces manual human verification with an automated script that clicks through the GUI and verifies the rendered state.

## Goals
1.  **Simulation Framework Setup:** Build a dedicated test script (`tests/visual_sim_mma_v2.py`) utilizing `ApiHookClient` to control the live GUI.
2.  **Simulate Epic Planning:** Automate the clicking of "New Epic", inputting a prompt, and verifying the expected Tier 1 tracks appear in the UI.
3.  **Simulate Execution & Spawning:** Automate the selection of a track, the generation of the DAG, and the interaction with the HITL Approval modal.

## Constraints
-   Must run against a live instance of the application using `--enable-test-hooks`.
-   Must fail loudly if the visual state (e.g., rendered DAG nodes, text box contents) does not match expectations.

## Context & Origins
This track was born from the "Human Verification" phase of the initial MMA Orchestrator prototype (`mma_orchestrator_integration_20260226`). We realized that while the backend API plumbing for the hierarchical MMA tiers (Tiers 1-4) was technically functional, the product lacked the necessary state management, UX visualization, and human-in-the-loop security gates to be usable. 

**Key Takeaways from the Prototype Phase:**
- The Tier 2 (Tech Lead) needs its own track-scoped discussion history, rather than polluting the global project history.
- Tasks within a track require a DAG (Directed Acyclic Graph) engine to manage complex dependencies and blocking states.
- The GUI must visualize this DAG and stream the output of individual workers directly to their associated tasks.
- We must enforce tiered context subsetting so that Tier 3/4 workers don't receive the massive global context blob, and we need a pre-spawn approval modal so the user can intercept, review, and modify worker prompts/contexts before they execute.

**Instructions for the Implementing Agent:**
As you execute this track, ensure you maintain alignment with the other Phase 2 tracks. If you learn something that impacts the dependent tracks, please append a similar "Context Summary" to their `spec.md` files before concluding your run.

## Execution Order & Dependencies
This is a multi-track phase. To ensure architectural integrity, these tracks **MUST** be executed in the following strict order:
1. **MMA Data Architecture & DAG Engine:** (Builds the state and execution foundation)
2. **Tiered Context Scoping & HITL Approval:** (Builds the security and context subsetting on top of the state)
3. **MMA Dashboard Visualization Overhaul:** (Builds the UI to visualize the state and subsets)
4. **[CURRENT] Robust Live Simulation Verification:** (Builds the tests to verify the UI and state)

**Prerequisites for this track:** `MMA Dashboard Visualization Overhaul` MUST be completed (`[x]`) before starting this track.
