Provenance

Every row carries Tülu-style lineage:

  • content_hash — sha256 over (system, user, assistant, site, is_noop, sha256(image bytes)); stable content identity (oversampled duplicate rows share it).
  • source<collection>/<site>, collection ∈ {webarena, liveweb}, inferred per trajectory (a trajectory touching the WebArena instance host is webarena).

Decontamination (report-only; no rows removed)

Checked at revision 1440b43cabc3178f0ead8d71a373eddad626570b: 8-gram word overlap of train prompts vs val_in/val_out prompts (GOAL/CURRENT URL/ACTION lines only), plus val_out site- and goal-template-identity (docs/plan/05-evals.md).

  • removal rate (flagged, not removed): 6.7% (58/870 train rows)
  • breakdown: ngram∩val_in 22, ngram∩val_out 6, exact prompt 0, val_out site 0, val_out template family 36
  • trajectories straddling train/val_out (site-wise split cuts multi-site trajectories row-wise): 5

Changelog

  • 2026-06-12 (rev c19f5c59ad43ad81a65ffd1193ec36431ac3ff3a): add content_hash + source provenance columns and record decontamination stats; data otherwise unchanged from 1440b43cabc3178f0ead8d71a373eddad626570b.
  • 2026-06-12 (rev 1654e81b99f447644be47b6abb14e657362cc630): decontamination removal per PR #12 review sign-off — drop the 5 train/val_out-straddling trajectories' rows from val_out (48 → 33). train and val_in unchanged.
