+# ChronoReplay-Train
+
+Portable training annotations for **ChronoReplay: One Answer Interface Is Not
+Enough for Streaming Spatial Intelligence**.
+
+This release contains all 39,561 selected serialized training records with
+their original questions, answers, order, loss weights, and supervised-turn
+masks. It contains **annotations and relative media references, not the
+referenced image/video files**.
+
+| Supervision | Serialized records |
+|---|---:|
+| Categorical preservation | 30,635 |
+| Numeric geometry / camera motion | 2,545 |
+| OST causal episodes | 6,381 |
+| Total | 39,561 |
+
+The OST episodes contain 45,006 supervised trajectory turns. The full pool
+references 946,256 unique media paths. This is a reference count; it does not
+assert that all media are present in this repository or independently mirrored.
+
+## Files
+
+- `data/train.parquet`: portable native training records.
+- `manifests/replay_selection.json`: original IDs, ordering, text hashes,
+  observation counts, weights, and supervision masks.
+- `manifests/media_paths.jsonl.gz`: unique relative paths referenced by the data.
+- `release_manifest.json`: conversion checks, component counts, and data hashes.
+
+Server-specific media prefixes were replaced with relative paths under `media/`.
+Internal conversion-certificate columns were omitted. Every native question
+and target was checked against the frozen per-record text hash; identifiers,
+ordering, weights, masks, and image counts were also checked for all records.
+The portable Parquet has a new file hash because its paths and schema differ
+from the original server artifact. No new samples or target answers were generated.
+
+## Use with the code release
+
+Download the annotations and obtain the source media under their applicable
+terms. Arrange media under the relative paths listed in the records. From the
+ChronoReplay code release:
+
+```bash
+python -m scripts.materialize_frozen \
+  --candidate downloaded/data/train.parquet \
+  --selection downloaded/manifests/replay_selection.json \
+  --media-root downloaded \
+  --output data/replay
+```
+
+The materializer verifies the frozen records and decodes every referenced
+image before declaring the pool ready. This annotations-only upload is not
+a self-contained media distribution.
+
+## Sources and terms
+
+Sources include the [OST-Bench training release](https://huggingface.co/datasets/rbler/OST-Bench),
+source-annotated categorical preservation examples, and
+[ARKitScenes](https://github.com/apple/ARKitScenes) camera-rotation and
+corrected-camera geometry supervision. Original source terms continue to apply.
+The OST training build records CC-BY-NC-4.0 for that component; this statement
+does not assign that license to the entire mixed-source pool.
+
+The [ChronoReplay collection](https://huggingface.co/collections/mis2/chronoreplay-6adc88dc1e468c2d2ae9bb44)
+links these annotations and the corresponding model; the preparation scripts
+are in the [code repository](https://github.com/yihaohu0118/ChronoReplay).
+This card does not assign a new blanket license to third-party source material.
+Media availability and current pixel identity have not been revalidated by
+this annotation conversion. No evaluation predictions or score artifacts are bundled.
+
+See `CITATION.cff` for citation information.
