feat(imf): multi-part release assets + one-command publish - #11
Merged
Conversation
…publish
heb-diac-1.0 fp32 (2.59 GiB) exceeds GitHub's hard 2GiB per-asset cap.
models.yaml entries may now carry parts: [{url, sha256, size}]; the
registry streams parts in order, verifies each sha256 as it lands, and
checks the assembled file against the whole-file sha256 — the cache
contract is identical to single-file models.
- scripts/split_release.py: split + per-part sha256 + models.yaml block
- scripts/publish_model.py: validate (strict) -> split -> GH Release ->
models.yaml entry -> release branch -> PR; idempotent re-runs
- runtime registry: parts resolution + tests (assembly, corrupt-part
rejection, verified cache hit)
