## v1.0 update - 2026-08
- Added the complete 9-bin event voxel representation.
- Normalized payload directories to `data_5bin/` and `data_9bin/`.
- Preserved the canonical 3,263-video membership and 2,316/947 split for both variants.
- Added representation-specific metadata under `metadata/5bin/` and `metadata/9bin/`.
- Generalized timing and format documentation for bin count `B` in `{5, 9}`.
- Verified 219 shards per representation and 438 total payload shards.
Canonical HDF5 payload sizes:
- 5-bin: 4,355,745,895,245 bytes;
- 9-bin: 4,214,122,096,103 bytes.
