si-jam-sessions v0.2.1

[0.2.1] - 2026-09-29

The same product as 0.2.0, published by Trusted Publishing so the registry copy carries a provenance
attestation. 0.2.0 was published from a local npm session and has no attestation. The law, the goldens and
the container are unchanged. The image tag for this publish is 0.2.1.

si-jam-sessions 0.1.0

The first release of si-jam-sessions: a music engine where an AI's playing can be graded exactly, replayed
exactly, and trained on with a clean conscience. What changed is in the
CHANGELOG.

The two exemplars

Two arrangements of Battle Hymn of the Republic, one by glm-5.3 and one by kimi-k3. Both follow this project's
transcription of the anonymous 1862 Ditson edition, both are dedicated CC0 1.0, and both are admitted by the
law's licence check. Each was rendered through the law on the Salamander Grand Piano V3 by Alexander Holm
(CC BY 3.0).
