Fetched the virdx/histo refs and inspected origin/main at d27ead6d without changing its worktree.
Documented the public histo.domain_representation imports and exact signatures for settings, model loading, and scan processing.
Confirmed that the pipeline consumes a WSI or preprocessed HistoScan plus an optional foreground mask, not an existing domain representation.
Documented model references, device and dtype behavior, output Zarr layout, run records, and release identifiers.
Identified an integration constraint: Hydra configuration lives outside src/histo and is not included in the wheel.
Lessons Learned: Pitfalls
The worktree branch was behind its remote and contained unrelated untracked files. Reading origin/main:<path> avoided conflating local state with the current interface.
Package version 0.0.127, pipeline version v2.0, and Git tag histo-v0.0.127 are distinct identifiers and must not be treated as interchangeable.
Lessons Learned: Improvements
Add packaged default configuration or a public default_settings() helper so installed-package adapters do not depend on a repository checkout.
Add a short integration contract that states explicitly that process_scan writes maps as side effects and returns a run-record dictionary rather than a representation object.
