medmlx 0.4.7

Breaking changes

medsam2 propagation stops after 8 consecutive empty slices in each direction, with medsam2-mlx 0.3.0. Pass "stop_after_empty": null in the run arguments to track through the whole volume as before.

Fixes

MedGemma runs from the documented 4-bit MedGemma 1.5 4B and MedGemma 4B checkpoints. Their folders hold one model.safetensors beside an index naming two shards, so 0.4.6 refused them with "Missing checkpoint shard". The bridge now refuses only a folder where some indexed shards are present and others are missing.

mlx-reason-ct is no longer refused on Macs with about 15 to 23 GB of free memory, with mlx-reason-ct 0.4.1. It declared a stale 22.7 GB peak; a chest or abdominal CT report peaks at 14.4 GB.

New

Most models now declare their peak memory, so medmlx refuses a run that would not fit before it starts. The README lists every model's peak. The runtime releases also add memory reductions, faster BioMedParse and MedSAM2 runs, and safer output writing; see each runtime's release notes.
