# Release Notes

## scientific-agent-protocol-traces-v2.1.0

- Replaced mixed native/v1 records with typed, normalized Parquet tables.
- Added stable problem, trajectory, event, agent, hypothesis, intervention, and label IDs.
- Disambiguated SciBench source-ID collisions by problem-text hash.
- Collapsed exact MaScQA duplicates and retained the decision in the crosswalk.
- Separated benchmark slice, actor model, evaluator model, compute site, backend, and release status.
- Added source-run versus publication-target coverage fields and release gates.
- Imported frozen Aurora and CRUX classic runs with per-file manifest checksums.
- Added generated benchmark accuracy and LAB-Bench filter-audit documentation.
- Bound all 40 classic comparison cells to frozen source manifests.
- Added provenance-checked token and request-submission measurements for
  39,918 Direct Baseline, Single-Agent Iterative, and Broadcast Deliberation
  trajectories across Gemma 4 31B and GPT-OSS 120B, plus direct per-problem
  elapsed time for all 53,224 matched trajectories. Planner–Executor–Reviewer
  token and request fields remain null because cumulative main-model and
  resetting memory-summary counters are not exactly separable after the fact.
- Kept matched four-protocol token oracles null whenever a successful protocol
  lacks token measurements, rather than treating unmeasured PER as absent.
- Normalized released cost-manifest problem and row identities to public
  trajectory keys while preserving their original source identifiers.
- For 11 trajectories in eight documented OmniMath2 partial reruns, aligned
  labels with the selected complete rerun: four final-answer correctness values
  and 11 first-pass correctness values changed. Final-answer labels are
  corroborated by the complete result and trace; first-pass labels come from
  the selected complete metric file. The released source manifests preserve
  both file identities, checksums, and the earlier values.
- Suppressed 9,500 inherited cost rows from supplemental GPT-OSS and Gemma-3
  slices that lack validated per-trajectory accounting and cost manifests;
  their released values remain null.
- Corrected SciBench broadcast row-level backend and source-commit provenance
  from its frozen base/recovery source manifest.
- Rebuilt composite licensing, Croissant metadata, checksums, and manifest.
