A response can be the after-score for one transition and the before-score for the next, but an older baseline is never reused. Stored overall and dimension scores are compared. The newest complete UTC calendar-week/scoring-version cohort that independently clears both minimums is reported, so historical versions cannot suppress current proof and the selected cohort cannot drift with daily additions; improvement_rate_percent is the share of those paired transitions where score_after is strictly greater than score_before. Self-report and non-random participation limit inference.","privacy":"No raw text or identifiers are returned. Counts below 10 are suppressed; complementary child totals are both withheld when either child is small. Closed-day counts use buckets of 10 to prevent temporal differencing. Legacy corpus caller identity is the existing one-way SHA-256 pseudonym (not a keyed hash); newly instrumented event telemetry uses a separate keyed hash.","retention":"Corpus and event rows follow the existing indefinite operator retention policy.
