+# Bundled model weights for online final-graph extraction
+
+This directory contains model checkpoints used by the reference real-time final-graph pipeline:
+
+```text
+models/sam2/checkpoints/sam2.1_hiera_base_plus.pt
+models/clip/ViT-B-32.pt
+models/MODEL_MANIFEST.json
+```
+
+They are used by:
+
+```python
+Sam2ClipRealtimeFeatureBackend(...)
+```
+
+Default lookup order:
+
+1. Explicit `sam2_checkpoint=` / `clip_checkpoint=` arguments.
+2. Bundled package paths above, when present in a local HF checkout/download.
+3. For CLIP only, OpenAI CLIP's normal `clip.load("ViT-B/32")` cache/download fallback.
+
+## Third-party notices
+
+These checkpoints are third-party model weights and are separate from the RoboCasa-derived graph dataset license-pending notice.
+
+- SAM2.1 Hiera-B+ checkpoint: from Meta/Facebook Research SAM 2. Users must comply with SAM 2 upstream model/code license terms.
+- CLIP ViT-B/32 checkpoint: from OpenAI CLIP. Users must comply with OpenAI CLIP upstream model/code license terms.
+
+This repository provides the weights only to make the reference online final-graph extraction pipeline directly runnable from a dataset checkout. It does not change or supersede upstream license terms.

+## Expected hashes
+
+See `MODEL_MANIFEST.json` for SHA-256 hashes and byte sizes.
