# Changelog

All notable changes to CM-EVS are documented here. The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [v1.0.0] — 2026-05-02 (initial release)

### Added

- **Blender indoor data drop**: 374 scene instances (`sence_indoor_0001 … sence_indoor_0374`), 13,631 ERP RGB frames + 12,634 range-depth NumPy arrays + 13,631 pose JSON files. Resolution 2048×1024. CC-BY 4.0.
- **Blender indoor metadata**: `source_manifest.json`, `splits.json` (scene-level 70/15/15 via `sha256(scene_id) % 100`), `frame_manifest.csv` (14 columns matching the Croissant RecordSet schema), `scene_id_mapping.csv` and `frame_id_mapping.csv` (back-references to original H100 round1+2 / round2 sampling).
- **Per-archive integrity**: `blender_indoor/SHA256SUMS` (39,896 lines covering panorama + depth + pose).
- **Adapter packages** for the four license-restricted sources: HM3D (401 rooms), ScanNet++ (500 scans), OB3D (24 instances, outdoor), TartanGround (762 parts, outdoor). Each package contains README, config, pipeline / re-encoding script, and `metadata/source_manifest.json` listing the upstream scene IDs needed to reproduce the curator's selection.
- **Curator source code** (`code/`): MIT-licensed core modules (`core/`), scripts (`scripts/`), helper tools (`tools/`), metadata schemas (`metadata_examples/`), tiny example (`examples/tiny_blender_scene/`), `environment.yml`, `requirements.txt`.
- **Croissant v1.0 metadata** (`croissant.json`): conforms to <http://mlcommons.org/croissant/1.0>; passes `mlcroissant 1.1.0` validator. 12 distribution entries (Blender archive + 4 FileSets + 4 adapter packages + code + docs + frame-manifest), 1 RecordSet (`erp-frame-records`) with 14 fields, 9 RAI extension fields.
- **Datasheet** (in `README.md`) following Gebru et al. 2021.
- **License matrix** (`LICENSE.md`).
- **Top-level integrity manifest** (`SHA256SUMS`) covering all non-data files.

### Notes

- The paper's headline numbers `326 scenes / 11,583 frames` describe the **curator-selected subset**, not the full data drop. v1.0 stages the underlying 374 / 13,631; the curator-selected subset will be derived after the §5 evaluation experiments finalize and posted as v1.1.
- **HM3D / ScanNet++ / TartanGround / OB3D**: zero RGB-D frames are redistributed under any license. The adapter packages reproduce matching frames on the user's machine after upstream access is granted.
- Frame numbers within each Blender scene are renumbered consecutively (`panorama_0000 … panorama_NNNN`); `frame_id_mapping.csv` records the back-reference to the original H100 file path for traceability.
