This pack holds the measurement data behind the report. Every number in the report can be
recounted from these files. Counts in the report come from summary.csv and per_engine.csv.

Files:
- summary.csv: One row per tracked name: answers naming it, appearance rate and 95% interval, first-mention position, own-domain citation, citation share, Google AI Overview counts and five-engine totals.
- per_engine.csv: The same counts split by engine (ChatGPT, Claude, Gemini, Perplexity).
- significance.csv: Pairwise comparisons between the leading names (z-test, p-value, whether the 95% intervals overlap).
- sources.csv: Cited domains: number of citations, share of all citations, and how many answers cited each domain.
- entity_rollups.csv: Spellings and name variants counted together with each tracked name.
- unmatched_names.csv: Names that appeared in answers but were not on the tracked list, unfiltered, with answer counts.
- status-decisions.json: Decisions on names in transition (mergers, renames), with the source used.
- trials.csv: One row per answer: engine, question, run, names found, citations, measurement time.
- raw_responses.jsonl: The full text of every answer and Google AI Overview, with its citations, one JSON record per line.
