# 06 Export Pipeline

## Required Export Formats

| Format | Use |
| --- | --- |
| PNG | sprites, UI, tiles, FX frames, previews |
| Texture Atlas | runtime batching and animation frames |
| JSON | frame metadata, pivots, collision, events |
| YAML | production definitions and approval metadata |
| Metadata | ownership, version, source links, QA score |
| Checksums | package integrity |
| Hashes | reproducible asset identity |

## Export Rules

- PNG files use RGBA.
- Transparent sprites must preserve alpha.
- Atlas exports must include frame names.
- JSON metadata must reference the source YAML ID.
- Checksums are generated after export, not before.
- Hashes change when visual output changes.
