# SpatialMirage Stage 2 Training Data
This public release contains the SpatialEdit-500K camera-control subset used by
SpatialMirage Stage 2. It contains 243,338 training pairs and 4,096
held-out construction-time evaluation pairs. The 6,344 original upstream
WebDataset shards occupy 125,005,230,080 bytes and preserve the original source and
target JPEG bytes without re-encoding.
The upstream dataset is `EasonXiao-888/SpatialEdit-500K` at revision
`e54a9c870f98487d63f789a5e1bde4d35937d227` and is distributed under Apache 2.0.
## Contents
* `annotations/train_stage2_spatialedit_camera_243338.jsonl` is the exact row set
used by the final Stage 2 recipe with portable image paths.
* `annotations/eval_stage2_spatialedit_camera_4096.jsonl` records the held-out
construction split.
* `raw/camera_control/*.tar` are byte-identical original upstream shards.
* `scripts/materialize_images.py` extracts only the images referenced by a chosen
annotation file.
## Materialization
```bash
python scripts/materialize_images.py \
--annotation annotations/train_stage2_spatialedit_camera_243338.jsonl \
--output-root /path/to/stage2_data
```
Resolve annotation paths against `/path/to/stage2_data` during training.
