## 2026-04-28 02:11 +05:30 - ZeroGPU PRD Implementation, Context Handoff
**Completed:**
- Treated `CLAUDE.md` as the project source of truth.
- Updated HuggingFace Space metadata in `README.md` to include `hardware: zero-gpu`, `sdk_version: '4.44.0'`, `app_file: app.py`, `pinned: true`, and `license: mit`.
- Reworked `app.py` to import `spaces`, load modules on CPU at startup, use real `modules.m3_sstgnn.SSTGNNModule`, and decorate `analyze()` with `@spaces.GPU(duration=120)`.
- Added GPU transfer methods to M1, M2, and M3 wrappers.
- Added SSTGNN architecture in `modules/sstgnn_model.py`.
- Added patch graph construction in `utils/graph.py`.
- Added local `lipfd/model.py` and `lipfd/__init__.py` so M1 import path exists.
- Generated `weights/fusion_mlp.pt` and updated `.gitignore` to allow that exact required checkpoint.
- Added `tests/test_zero_gpu_contract.py` to lock the ZeroGPU contract.
**Broke / Fixed:**
- Initial contract test failed because README lacked ZeroGPU metadata, `app.py` imported `m3_fallback`, module wrappers lacked transfer methods, and `modules/sstgnn_model.py` was missing.
- Fixed those failures and verified the contract tests pass.
- Found missing `lipfd/model.py` and added it.
- Found `.gitignore` ignored all `.pt` files and added `!weights/fusion_mlp.pt`.
**Verification:**
- `pytest tests/test_zero_gpu_contract.py -q` passed.
- `pytest tests/test_fusion.py -q` passed.
- `python -m py_compile` passed for touched Python files.
- Full suite passed: `59 passed, 9 warnings`.
**MCP / Context Store:**
- Tried to use MCP for Obsidian context.
- `list_mcp_resources` returned no resources.
- `list_mcp_resource_templates` returned no templates.
- Because Obsidian MCP is not exposed in this Codex session, wrote a local fallback vault mirror under `Obsidian/GenAI-DeepDetect/`.
**Next Session Starts With:**
- Connect Obsidian MCP and sync this local fallback folder into the real Obsidian vault.
- Verify HuggingFace weight repos are accessible.
- Replace minimal LipFD wrapper with full upstream model files if checkpoint loading reports missing or unexpected key issues.
- Run the Gradio Space on ZeroGPU with a real video sample and configured `NVIDIA_API_KEY`.
**Changed Paths / Model IDs:**
- `README.md`
- `app.py`
- `.gitignore`
- `requirements.txt`
- `modules/__init__.py`
- `modules/m1_lipsync.py`
- `modules/m2_fingerprint.py`
- `modules/m3_sstgnn.py`
- `modules/m5_explain.py`
- `modules/sstgnn_model.py`
- `utils/graph.py`
- `lipfd/__init__.py`
- `lipfd/model.py`
- `weights/fusion_mlp.pt`
- `tests/test_zero_gpu_contract.py`
- `Obsidian/GenAI-DeepDetect/README.md`
- `Obsidian/GenAI-DeepDetect/module-status.md`
- `Obsidian/GenAI-DeepDetect/blockers.md`
- `Obsidian/GenAI-DeepDetect/session-log.md`
- HF model IDs: `AkshatAgarwal/LipFD-checkpoint`, `AkshatAgarwal/SSTGNN-deepfake`, `yermandy/deepfake-detection`, `openai/clip-vit-large-patch14`.
- NVIDIA NIM model ID: `meta/llama-3.1-8b-instruct`.
