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 6c6f8ad64fa67bf08353e7de703a42ec22636f5a: 8-gram word overlap of train prompts vs valin/valout 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): 9.9% (47/476 train rows)
—breakdown: ngram∩valin 22, ngram∩valout 6, exact prompt 0, valout site 0, valout template family 25
—trajectories straddling train/val_out (site-wise split cuts multi-site trajectories row-wise): 5

Changelog

—2026-06-12 (rev 6ccb3aae07e2f7dcb22f1cc535354e81f99dd9e3): add content_hash + source provenance columns and record decontamination stats; data otherwise unchanged from 6c6f8ad64fa67bf08353e7de703a42ec22636f5a.
—2026-06-12 (rev 4ea38deac64c3932e0fedc5eb4111b78814d1bec): decontamination removal per PR #12 review sign-off — drop the 5 train/valout-straddling trajectories' rows from valout (48 → 33). train and val_in unchanged.
