+# Implementation Plan: Stage-Based Pipeline Refactor
+
+Refactor the Fox CARLA ADAS simulation pipeline to separate concerns across environment management, data processing, and serialization. This moves the project from a monolithic `main.py` to a modular, stage-based architecture.
+
+## User Review Required
+
+> [!IMPORTANT]
+> **Dashboard Telemetry Persistence**: The Dashboard backend (`app.py`) parses specific `stdout` patterns like `[SHENRON_STEP]` and `[AUTO-MCAP]`. We must ensure the new `PipelineManager` or the individual stages continue to emit these strings to avoid breaking the UI progress bars.
+
+> [!WARNING]
+> **Resource Management**: During the transition from `SimulationStage` to `ShenronStage`, we must explicitly ensure CARLA's synchronous mode is either released or the process is handled such that GPU memory is freed for the heavy Shenron Torch operations.
+
+## Proposed Changes
+
+---
+
+### [NEW] Pipeline Core (`src/pipeline/`)
+
+Establish the foundational classes for stage-based execution.
+
+#### [NEW] [base.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/pipeline/base.py)
+- Define `PipelineContext`: Dataclass to carry `session_path`, `scenario_config`, and `args`.
+- Define `PipelineStage`: Abstract Base Class with `run(context)` and `cleanup()` methods.
+
+#### [NEW] [manager.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/pipeline/manager.py)
+- Implement `PipelineManager`: Orchestrates the execution of a list of `PipelineStage` objects.
+- Handles error propagation and graceful halts.
+
+---
+
+### [NEW] Processing Layer (`src/processing/`)
+
+Extract physics and data-augmentation logic to make it reusable and testable.
+
+#### [NEW] [physics.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/processing/physics.py)
+- **`calculate_radial_velocity`**: Extracted from `recorder.py`. Calculates line-of-sight velocity for LiDAR points.
+- **`compute_adas_metrics`**: Extracted from `recorder.py`. Calculates range, azimuth, and closing velocity for NPCs.
+
+---
+
+### [MODIFY] Simulation & Recording
+
+Clean up existing components to focus on their primary responsibilities.
+
+#### [MODIFY] [recorder.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/recorder.py)
+- Remove physics calculation logic.
+- Update `save()` to accept pre-calculated metrics.
+- Move `_generate_videos` to a utility function.
+
+#### [MODIFY] [main.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/main.py)
+- Remove monolithic simulation loop.
+- Transform into a thin wrapper that initializes `PipelineManager` with `SimStage`, `ShenronStage`, and `McapStage`.
+
+---
+
+### [NEW] Pipeline Stages (`src/pipeline/stages/`)
+
+Encapsulate logic into discrete execution units.
+
+#### [NEW] [sim_stage.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/pipeline/stages/sim_stage.py)
+- Port the CARLA simulation loop from `main.py`.
+- Manage `SensorManager` and `Recorder` lifecycles.
+
+#### [NEW] [shenron_stage.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/pipeline/stages/shenron_stage.py)
+- Wrap `scripts/generate_shenron.py` logic.
+- Ensure `[SHENRON_STEP]` telemetry is emitted.
+
+#### [NEW] [mcap_stage.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/pipeline/stages/mcap_stage.py)
+- Wrap `scripts/data_to_mcap.py` logic.
+- Register Foxglove schemas and handle final serialization.
+
+---
+
+## Verification Plan
+
+### Automated Tests
+- **Physics Parity Test**: Create a script in `scratch/` that runs the old `recorder.py` logic and the new `physics.py` logic on the same frame to ensure bit-identical results for radial velocity and ADAS metrics.
+- **Pipeline Dry-Run**: Run the pipeline with `--skip-sim` on an existing data folder to verify that `ShenronStage` and `McapStage` correctly identify and process the files.
+
+### Manual Verification
+- **Dashboard Validation**: Launch the Dashboard via `dashboard.bat`, trigger a simulation, and verify that:
+ 1. The console log shows the new stage transitions.
+ 2. The progress bars for Shenron and MCAP update correctly.
+- **Foxglove Check**: Open the generated `.mcap` in Foxglove and verify that the LiDAR (with radial velocity) and Radar pointclouds are visualized correctly.

+# Fox v1.1 Release Walkthrough
+
+This release marks a major architectural shift from a monolithic script to a modular, stage-based pipeline, while simultaneously achieving full feature parity with the high-fidelity `test_shenron.py` radar testbench.
+
+## ๐ Key Achievements
+
+### 1. Unified Radar Physics & Visualization
+- **Single Source of Truth**: All radar plotting and post-processing logic is now centralized in `scripts/ISOLATE/sim_radar_utils/plots.py`.
+- **FastHeatmapEngine**: Migrated the production pipeline to the stateful rendering engine, resulting in consistent dB scaling and improved performance.
+- **Dual RA Stream**: Range-Azimuth (RA) visualization now produces both a **Static** (absolute magnitude) and **Dynamic** (peak-tracking) stream for Foxglove.
+- **3D FOV Frustums**: Added hardware-accurate 3D frustum wireframes for all radar types (AWRL1432 and RadarBook).
+
+### 2. Modular Stage-Based Pipeline
+- **PipelineManager**: Orchestrates the execution of discrete stages: `Simulation` โ `Shenron` โ `MCAP` โ `Video`.
+- **Feature Parity**: Ported advanced telemetry flattening and metrology math from the testbench to the production exporter.
+- **Selective Execution**: New CLI flags allow running only specific stages (e.g., `--only-mcap` to re-process existing data).
+
+### 3. Robustness & Portability
+- **Pathlib Integration**: Replaced brittle `os.path` joins with robust `Pathlib` logic in all pipeline stages and the orchestrator.
+- **Stop Flag Detection**: Fixed a path bug in the stop flag detection to ensure graceful simulation shutdown works reliably across different working directories.
+- **Hardware Persistence**: Added `radar_specs.json` generation to save hardware constants (carrier frequency, velocity limits) during synthesis for downstream visualization.
+
+## ๐ ๏ธ Verification Results
+
+| Component | Status | Verification Detail |
+|---|---|---|
+| **Dashboard** | โ
| Version bumped to v1.1; scenario list and status polling verified. |
+| **SimStage** | โ
| Verified ego spawn, weather application, and `stop.flag` path resolution. |
+| **ShenronStage** | โ

+| **McapStage** | โ
| Verified `FastHeatmapEngine` initialization and `ISOLATE` path handling. |
+| **Telemetry** | โ
| Verified flattened schema for Foxglove Plot panel compatibility. |
+
+## ๐ฆ File Audit Summary
+
+- `src/main.py`: Refactored to thin CLI wrapper for `PipelineManager`.
+- `src/pipeline/*`: New core architecture for stage management.
+- `src/recorder.py`: Decoupled from physics logic; focused on raw capture.
+- `src/processing/physics.py`: Reusable physics layer for radial velocity and ADAS metrics.
+- `scripts/data_to_mcap.py`: Upgraded to v1.1 with testbench parity and 3D diagnostics.
+- `dashboard/templates/index.html`: UI updated to reflect v1.1.
