Inspected all 159 fetched origin/* refs and recent commits in /Users/felix.knispel/work/histo.
Located the September shared embedding extractor commits and compared their API with histo-v0.0.127.
Confirmed that histo-v0.0.127 packages the in-memory FeatureGrid, extract_embeddings, and high-level Gleason extraction/decode wrapper.
Confirmed that no fetched branch adds a stable path-backed embedding artifact, FeatureGrid serialization, or package-level save/load API. Persistence search hits belong to experiments and scripts.
Lessons Learned: Pitfalls
Method names such as predict_wsi_embeddings suggest that embeddings are returned, but the method immediately decodes the grids and returns segmentation arrays.
Broad commit-subject searches miss the distinction between in-memory extraction and persistent artifact support; source-level searches across every remote tip were necessary.
Lessons Learned: Improvements
A short Histo API inventory that distinguishes package APIs from experiment-only persistence would make future integration checks faster.
Document that FeatureGrid is an in-memory dataclass with no serialization contract as of histo-v0.0.127.
