4.0.1

• decouple tissue mask preview from tiling preview (#117)
• add config knob to control sam2 worker count to avoid CUDA OOM (#119)

4.0.0

Unified tiling interface

tiling and annotation-aware sampling are now a single workflow driven by one entry point:

hs2p /path/to/config.yaml

Breaking changes

• config: tiling.sampling_params → tiling.masks (pixel_mapping, colors, min_coverage)
  • tiling.params.tissue_threshold is folded into tiling.masks.min_coverage.tissue
• output layout: tiles/{annotation}/{sample_id}.coordinates.* for named annotations
  • collapses to tiles/{sample_id}.coordinates.* when annotation is tissue (the default)
• tar artifacts: {sample_id}.{annotation}.tiles.tar
  • collapses to {sample_id}.tiles.tar for the tissue default
• process list: gains an annotation column, always populated (tissue for the binary default)

Internal

• hs2p/preprocessing.py and hs2p/api.py split into a focused hs2p/tiling/ package (result, contours, coverage, generate, mask, io, single, tar, orchestration); both originals are now thin re-export shims
• 3 duplicate cv2.integral coverage implementations consolidated into tiling/coverage.py
• dead wsi/api.py sampling engine, wsi/utils.TissueFilter, and unused WSI sampling methods removed
