License applies to original summaries and compilation, not linked source documents. UTF-8 CSV: one row per incident; stable id joins to JSON records. JSON: metadata object containing records array. event_date uses YYYY-MM-DD or YYYY-MM, qualified by date_precision and date_basis. Unknown values are described explicitly, never replaced with zero. response_status distinguishes recorded positions from unavailable statements. prevention_analysis is editorial analysis, not a causal finding or guarantee. source_scope records partial access; reviewed_at is the verification date. Four selected records with documented milestones in 2022–2024 are not a prevalence estimate or trend series. A decision date may be used when an interaction/filing date is unknown; always read date_basis. Versioned snapshots: hallucination-tracker-v1.0.csv/.json and hallucination-tracker-v1.1.csv/.json. Repository: https://github.com/binny-gill/hallucination-free.org The repository archive-review ledger is an unverified editorial backlog, not this dataset. Changes: v1.1 adds HF-003 (Park) and HF-004 (Google AI Overviews). v1.0 initial release with HF-001 and HF-002.
