-TRACE (Temporal Audit and Condition-aware Evaluation of Streaming Video
-Understanding) provides visual-only timestamped video QA and Proactive Response
-annotations derived from StreamingBench and OVO-Bench.
+## How TRACE works
 
-This directory is a **private publication staging copy**. The OVO-Bench
-annotation redistribution terms and the applicable upstream rights for
-source-derived fields must be confirmed before making the Hugging Face dataset
-public. A gated repository does not replace that permission.
+<p align="center">
+  <img src="assets/trace-evaluation-design.png" alt="TRACE evaluation design from causal video input through the evaluation core, model adapter, model or system, and scoring" width="100%">
+</p>
 
-## Release contents
+TRACE separates causal video delivery, model interaction, and scoring. The same
+public contract makes QA and Proactive Response results auditable across models:
 
-- `data/v1.1.0/qa.jsonl`: 833 QA records.
-- `data/v1.1.0/proactive.jsonl`: 415 Proactive records and 1,338 response windows.
-- Tiny, standard, and sampling-stress subset files.
-- Release manifest, SHA-256 hashes, validation report, review summary, changes,
-  and exclusions.
+- **QA:** answer a question using only the video evidence available when it arrives.
+- **Proactive Response:** produce the requested response inside the annotated event or state window.
+- **Traceability:** retain source identities, release hashes, temporal annotations, and validation artifacts.
 
-The canonical release is `v1.1.0`; the local historical `v1.0.0` directory is
-intentionally not included. No videos or model weights are included. Each
-`video_path` is a relative provenance/path identifier; users must obtain the
-permitted source videos from their upstream providers.

+| QA | 833 | — |
+| Proactive Response | 415 | 1,338 |

-The release includes public ground truth for evaluation, not model input.
+This repository contains the frozen `v1.1.0` annotation snapshot. It does not
+include videos or model weights. `video_path` values are relative provenance
+identifiers; users must obtain permitted source videos from their upstream
+providers.

+## Files
+
+- [`data/releases/v1.1.0/qa.jsonl`](data/releases/v1.1.0/qa.jsonl): canonical QA records.
+- [`data/releases/v1.1.0/proactive.jsonl`](data/releases/v1.1.0/proactive.jsonl): canonical Proactive records and response windows.
+- [`data/releases/v1.1.0/manifest.json`](data/releases/v1.1.0/manifest.json): release identity, counts, and SHA-256 hashes.
+- [`data/releases/README.md`](data/releases/README.md): complete file inventory and field reference.
+- [`docs/dataset-card.md`](docs/dataset-card.md): populations, review coverage, and limitations.
+
+The release also includes tiny and Proactive subset definitions, review change
+and exclusion ledgers, a review summary, and a validation report. Keep these
+sidecar files together when verifying the manifest.
+
+## Data terms and limitations
+
+This dataset contains public ground truth for evaluation, not model input.
 Timestamps use the original video time coordinate and intervals are half-open.
-Review coverage and known limitations are recorded in `review_summary.json`,
-`validation_report.json`, and the release field reference.
+Review coverage and known limitations are recorded in the release artifacts.
 
-See `DATA_TERMS.md`, `THIRD_PARTY_NOTICES.md`, and `CITATION.cff` before use.
-TRACE-owned additions are separately described in the data terms; the MIT code
-license does not relicense upstream data or videos.
+Please read [`DATA_TERMS.md`](DATA_TERMS.md) and
+[`THIRD_PARTY_NOTICES.md`](THIRD_PARTY_NOTICES.md) before use. TRACE-owned
+additions are separately described there; the MIT code license does not
+relicense upstream data or videos. Upstream redistribution permissions must be
+resolved before making this dataset public.
 
-## File reference
+## Citation
 
-See `data/releases/README.md` for the complete v1.1.0 file inventory and field
-definitions. The corresponding TRACE implementation and video setup guidance
-are maintained in the upstream `trace-bench` code repository.
+See [`CITATION.cff`](CITATION.cff) for the TRACE citation and upstream
+attribution requirements. When reporting results, include the data release,
+protocol, and scorer versions used.
