+description: Maintain Windows-native PDFtoMD runtime behavior. Use when Codex needs guidance for repo-local venv, CUDA/OOM handling, Korean paths, long paths, model cache, offline operation, stderr logs, or resume cache behavior.
+---
+
+# Windows Runtime
+
+## Workflow
+
+1. Read `AGENTS.md`, `docs/TOOLCHAIN.md`, `docs/ARCHITECTURE.md`, and `docs/CONVERSION_POLICY.md`.
+2. Verify environment health with:
+   - `.\venv\python.exe -m pip check`
+   - CUDA smoke test
+   - `.\venv\Scripts\nougat.exe --help`
+3. Use `pathlib` for path design and tests.
+4. Include Korean filenames, spaces, and long Windows paths in test plans.
+5. Keep model cache and offline behavior explicit.
+
+## Guardrails
+
+- Do not silently fall back to CPU when the user explicitly requested CUDA.
+- Do not choose batch sizes that assume more than 8 GB VRAM.
+- Do not delete local environments or sample PDFs without explicit approval.
