 # Luau Stack HQ
 
-Luau Stack HQ is a highly curated & deduplicated Luau source code from github repository with linter `(stylua)`, it contains **~36.72M** tokens `(28024 unique files & 378 unique repo)`. It is built strictly for the training stages, providing a pristine density of type-safe, functional architecture without the noise of standard web scrapes.

+## # Filtering Pipeline
+
+To ensure the highest quality data for pretraining, the dataset was built using a rigorous, multi-step extraction and filtering pipeline:
+
+* **Repository Selection:** * **Target Terms:** Searches focus on `rbx`, `rblx`, `roblox`, and `luau`.
+    * **Quality:** Minimum of 5 stars.
+    * **Relevance:** Because Luau is updated frequently, only repositories active or pushed within the last 2.5 years are included.
+    * **Repo Deduplication:** Forks are strictly excluded.
+* **Auto-Formatting (`StyLua`):** Every raw `.luau` and `.lua` file is piped through `StyLua` to ensure consistent syntax. Unparseable files are dropped.
+* **Cheat & Exploit Removal:** * Repositories with cheat-related keywords in their name, description, or topics (e.g., `aimbot`, `executor`, `synapse`, `krnl`) are blacklisted.
+    * Code containing Roblox exploit globals (e.g., `getfenv`, `setfenv`, `hookfunction`, `loadstring`, `getrawmetatable`) is entirely discarded.
+* **Noise Reduction:** Test files, mocks, `.spec.` files, and compiled `/dist/` directories are ignored. Files smaller than 100 bytes or larger than 1MB are also excluded.
