Publish the selected 523330-parameter refinement with its frozen calibration, portable inference, updated model card and external-baseline report. Remove superseded runtime/evidence from main; prior release remains in history. Excludes private user recordings, plots and source metadata.
Remove locally trained Perch bat and rodent classifiers from all current report tables, charts and paired scores. Keep the published native mouse/rat species-head comparison, its unchanged input protocol and source limitations. Remove superseded classifier coefficients and reports from the current release. Ultrafauna weights, inference and calibration unchanged.
Add matched Google Perch baseline and mouse/rat call evaluation
Score frozen Perch2 bat classifier on the same 662 windows; evaluate released rodent output against Google native species head and a fixed TRAIN-only Perch rodent classifier on 341 windows from 13 recordings. Add ROC charts, training/overlap disclosures, paired scores, portable baseline coefficients and frozen evaluation sources. Released Ultrafauna weights, runtime and calibration remain byte-identical.
Compare released checkpoint against matched external bat baselines
Replace headline internal before/after tables with the unchanged uploaded checkpoint against BattyBirdNET EU and two BatDetect2 configurations on 662 matched saved examples. Add external ROC curves and paired-score provenance; move internal training history to DEVELOPMENT.md. Model weights and calibration remain byte-identical.
