HistoAnnotator v1.3.0-alpha.3

Pre-release checkpoint for the new annotation workflow, Tissue ROI analysis region, Artifact handling, and valid-tissue statistics.

Highlights

• Focus Mode with configurable keyboard shortcuts and compact class access.
• Review workflow with Draft / Reviewed / Approved lifecycle, review decisions, provenance, and batch workflow actions.
• Tissue ROI as a protected structural analysis region.
• Manual Tissue ROI drawing and server-side tissue detection.
• Non-destructive external Tissue ROI border exclusion with persistent base/effective ROI visualization.
• Built-in Artifact class:
  • always available;
  • normal drawing/editing/reclassification;
  • included in Review Mode and provenance;
  • reserved class name/configuration;
  • used as an exclusion mask for valid-tissue statistics.
• Valid Tissue statistics:
  • Tissue ROI or full image as analysis base;
  • optional external border exclusion;
  • Artifact union subtraction;
  • biological class areas reported against the remaining valid tissue.
• Fill unannotated tissue:
  • computes remaining valid tissue after existing annotations;
  • interactive preview;
  • choose the target class before creating a Polygon/MultiPolygon annotation.
• Annotation-file deletion with Default protection and local-first synchronization safeguards.
• UI refinements for compact annotation-file controls and non-blocking remaining-tissue preview.
