Clarify spelling update affects labels as well as ABC notation
Verified signatureClarify that the spelling correction updates key/chord labels and ABC notation while preserving musical pitches, timing and model weights.488abe2 -
Correct chord spelling with local keys and canonicalize key labels
Verified signatureApply the SheetSage2 LM chord-spelling scorer at each chord midpoint in LAB, ABC and playback exports. Canonicalize key labels using the LM/NoLM key map without changing numeric token IDs or the vocabulary fingerprint. Verify pitch spelling against NoLM, preserve raw decoded chord events, and add regression coverage for key changes, inversions, in-memory exports, paper mode and melody-only mode.e8b16e3

Add complete JAAH Maj/min chord evaluation and confidence intervals
Evaluate all 113 JAAH recordings: SheetSage2-AR 64.50%, ChordFormer 59.45%, and Prober 62.94% Maj/min recall. Document reference-span scoring, coverage, per-track scores, fixed-model provenance, and paired BCa intervals. Preserve previous benchmarks and the Chords1217 five-fold explanation.2c45f22

Replace chord specialist with verified ChordFormer benchmarks
Verified signatureUse the released ChordFormer models on osu2017 (86.55%) and held-out Chords1217 folds (83.94%), rescored with the common SheetSage2 protocol. Explain the aggregation change in the five-fold footnote. Add exact benchmark results, per-track scores and hashes, and a portable frozen scorer. SheetSage2 scores and inference settings are unchanged.7cb7b16 -
Update rhythm benchmarks and Beat This! three-seed evaluation
Verified signatureRefresh beat/downbeat results using a shared 5-second exclusion protocol. Beat This! is evaluated under its original settings and reported as the mean across three released training seeds. Synchronize benchmark_results.json, document track counts and scoring settings, and rename the displayed key metric to Score.cd2f39b
