CHANGELOG

All notable changes to TRACE are recorded here, starting with v1.0.0. Future releases will follow semantic versioning:

• Patch (v1.0.x) — typo fixes, metadata tweaks, no change to the JSONL splits.
• Minor (v1.x.0) — additions to the taxonomy or new teaching methods; existing examples preserved; new examples appended to splits.
• Major (v2.0.0) — schema changes or re-generations that invalidate prior splits; prior versions remain accessible via git tags.

v1.0.0 — 2026-04-25

Initial public release. 2,999 examples split across train (2,549) / valid (149) / test (281) / sanity (20). Paired with the dataset card, datasheet (Gebru et al. 2021), and data statement (Bender & Friedman 2018).

What's covered

• Teaching programs across three methods — DTT (800), NET (500), Task Analysis (500, including toleration programs).
• Session interpretations — 1,200 multi-session behavioral logs across 12 trajectory patterns with 13 target behaviors.
• Provenance — every example carries full meta.provenance.taxonomy_cells for auditable traceback.
• Reproducibility — the corpus regenerates byte-identically from (configs, seed) on any platform; every example_id is verifiable as sha256(user_content + assistant_content)[:16] directly from the published JSONL row.

Known limitations

See the dataset card section 6 and the data statement section H for the full list. Most notable:

• English-only, US clinical register.
• Pattern frequencies are uniform for learnability rather than epidemiologically weighted.
• VB-MAPP + AFLS only.
• Single-reviewer clinical validation.
