SN21 rich training data v3 (slice 2)
About SN21 AdTAO
SN21 rich training data v3 — slice 2. 7,132 reconstructed daily-stream episodes with settled 7/14/28-day labels, windows 2026-08-05 to 2026-08-14, continuing v2 (training-v2-2026-08, windows to 2026-08-04). Same record shape as v2, plus account_state.goal_basis inline on every record. Labels. cost, conversions, CPA and conversion-value deltas vs a 60-day pre-change baseline, measured over the 7, 14 and 28 days after the change window, each with a 7-day settling period for late conversions. Every window in this slice is old enough for all three horizons to have settled. goal_basis. account_state.goal_basis is inline on every record: the efficiency metric (cpa or conversion_value) the episode is graded on, resolved with the scorer's cascade (configured goal -> taxonomy -> cpa) and zero-baseline guard on the episode's own pre-window conversion value. Resolved against current account state, so an account retagged since its window may differ from how it resolved then; both cpa and conversion-value deltas are in the labels either way. Records whose basis could not be resolved were left out, not defaulted. What this is drawn from. Episodes are reconstructed from real account change history whose outcome windows have already elapsed; labels are measured results, not simulations. Campaign identifiers are one-way hashes. This release is a bounded slice that continues v2; later windows are released in further slices once their outcomes have settled and the held-out evaluation set has moved past them. Known limits. account_state.archetypes are detections within 30 days before the change. Outcome deltas naturally skew negative: many real changes intentionally reduce volume. source_mix derives from the Google Ads client type: web/mobile interfaces count as user, scripts/API/rules as system. A held-out evaluation set is retained and never published; it is drawn from windows after this slice, and any training episode overlapping it has been removed.
