+\# 🧱 Architecture Overview
+
+
+
+This page explains the modular architecture of the \*\*LCS Video Pipeline\*\*, covering key components, data flow, and extensibility.
+
+
+
+---
+
+
+
+\## 🧩 Core Modules
+
+
+
+Each component is designed to be loosely coupled and highly testable:
+
+
+
+\### 1. `main.py`
+
+
+
+\* Entry point
+
+\* Discovers session folders and orchestrates processing
+
+
+
+\### 2. `modules/`
+
+
+
+Contains reusable components:
+
+
+
+\* `render\_engine.py`: Applies intros/outros and overlays
+
+\* `title\_utils.py`: Generates dynamic title cards
+
+\* `thumbnail\_utils.py`: Creates brand-compliant thumbnails
+
+\* `yt\_poster.py`: Uploads to YouTube
+
+\* `pt\_poster.py`: Uploads to PeerTube (WIP)
+
+\* `description\_gen.py`: Creates OpenAI-based video descriptions
+
+\* `date\_utils.py`, `config.py`: Environment and date helpers
+
+
+
+---
+
+
+
+\## 🔄 Data Flow
+
+
+
+```plaintext
+
+\[raw clips] → \[montages/, hits/, etc.] → main.py → render\_engine → final.mp4 → yt\_poster
+
+```
+
+
+
+All clip metadata (e.g., `notes.json`) is parsed and tracked alongside rendered files.
+
+
+
+---
+
+
+
+\## 🧰 Tooling \& Configuration
+
+
+
+\* \*\*`.env`\*\*: Stores API keys and client secrets (excluded from Git)
+
+\* \*\*`config.py`\*\*: Centralized paths, flags, and constants
+
+\* \*\*`logs/`\*\*: Execution logs, status, and failures
+
+\* \*\*`tests/`\*\*: Pytest-based functional coverage
+
+\* \*\*`video-pipeline.wiki/`\*\*: Markdown wiki repo (submodule)
+
+
+
+---
+
+
+
+\## 🚧 Extensibility
+
+
+
+\* Add new platforms (e.g., TikTok) via new `poster\_\*.py`
+
+\* Add formats (e.g., square, cinematic) by enhancing `render\_engine.py`
+
+\* Add more metadata (e.g., voice notes) by expanding `notes.json` parser
+
+
+
+---
+
+
+
+\## 🧠 Design Philosophy
+
+
+
+\* \*\*Single responsibility per module\*\*
+
+\* \*\*Declarative configuration\*\*
+
+\* \*\*E2E traceability via metadata\*\*
+
+\* \*\*Fun, brand-forward visual output\*\*
