jam-actions-v0 (public subset) — AI Jam Sessions tool-use traces, v0.6.0 correction release

jam-actions-v0 is a corpus of multi-turn MCP (Model Context Protocol) tool-use traces grounded in classical-piano MIDI. Each record pairs a short phrase window (typically 4 measures) with an annotated teaching target and a target trace in which an assistant uses the ai-jam-sessions MCP tools to read, analyze and discuss the phrase. Version 0.6.0 is a correction release. Versions 0.4.3 (10.5281/zenodo.20279919) and 0.5.0 (10.5281/zenodo.21313954) contained 115 records across 8 compositions, all attributed to Bernd Krueger / piano-midi.de under CC-BY-SA-3.0-DE. An audit of the source library from the MIDI bytes found that four of those songs (Chopin Op. 9 No. 2 and Op. 28 No. 4, Beethoven Op. 13 II, Schumann Op. 15 No. 7) had been built from files obtained from midiworld.com and bitmidi.com that carry no established arrangement licence. The 58 records built from them are withdrawn; do not redistribute them from the earlier versions. The 57 remaining records, from Bernd Krueger's arrangements of Bach BWV 846, Mozart K. 545 I, Beethoven WoO 59 (Für Elise) and Debussy's Clair de Lune, are byte-identical to 0.5.0. The held-out test song is clair-de-lune (12 records); the train split is 45 records. This version is deposited separately from the earlier versions because their concept DOI (10.5281/zenodo.20279918) also holds versions of the distinct jam-actions-v1 dataset. The packaging now includes a library evidence gate: a record ships only if its song's provenance, re-derived from the MIDI bytes, names a redistributable arrangement licence and the record's source-file hash equals the evidenced file. Licensing: compositions are public domain (US + EU). MIDI arrangements by Bernd Krueger / piano-midi.de under CC-BY-SA 3.0 (Germany). Derivative records under CC-BY-SA-3.0 (DE) via share-alike; Zenodo's licence slug is the international form, and the DE jurisdiction is documented in ATTRIBUTION.md and LICENSE-DATASET.md.
