-| Batch video counting | `chicken-detection-model-v26n-300e-best-2026-05-02-NEW.onnx` (speed) or `.pt` (accuracy) |

+| Purpose | File | Notes |
+| :--- | :--- | :--- |
+| Batch video counting (TensorRT) | `models/chicken-detection-model-v26n-300e-best-2026-05-02-NEW.engine` | Maximum GPU throughput |
+| Base PyTorch weights | `models/chicken-detection-model-v26n-300e-best-2026-05-02-NEW.pt` | Used for portable runs and auto-recompiling engines |
+| Mortality detection | `models/chicken-detection-model-v26n-seg-300e-best-2026-04-18.pt` | 2-pass segmentation model |
 
-Update `configs/mortality_config.yaml` and `configs/cycle7_batch_optimized.yaml` if using different filenames.
+> **Self-Healing Recompilation on New Machines**: If you move the project to a new machine with a different GPU or OS, the pipeline will detect any incompatible `.engine`, automatically locate the matching `.pt` model, recompile a new `.engine` for the host machine, and update `configs/cycle7_batch_optimized.yaml` automatically.
