MOVIE BATTLE B3: CREW DATA AND COVERAGE Battle-only extension of the immutable Movie Night M1 catalogue. 794 film QIDs, 23,891 available non-deprecated credits, 13,901 stable person QIDs. Actors 19,535; directors 866; writers 1,755; cinematographers 817; composers 918. All available source credits are retained rather than truncating cast to twelve. Wikidata can still omit or misstate credits; this is not full real-world coverage. Source: https://www.wikidata.org/ Structured data and labels: CC0 1.0 https://creativecommons.org/publicdomain/zero/1.0/ Source properties: actors P161, directors P57, writers P58, cinematographers P344, composers P86. Role IDs come from the exact archived film entities already retained under data/movie-night; the archive SHA identifies source bytes. The archive lacks individual lastrevid values: none are fabricated. Names are 13,728 English labels plus 173 documented multilingual fallback labels, not raw QIDs. Reproducible importer: scripts/import-battle-credits.mjs. Provenance, cached SPARQL label batches, archive hash and independent streaming audit: data/movie-battle/. Browser module: src/movieBattleCredits.mjs. Stable QIDs distinguish namesakes and unify one person across roles. Existing Movie Night M1 factual categories, rarity proxy, fixtures, scores and saves are unchanged. No competitor film bank, poster collection, source code, IMDb dataset, runtime AI or paid API imported. Genre and Wikimedia-coverage values remain from the frozen M1 bank; coverage is not CineNerdle most-played ranking, TMDB popularity, audience demand or box office.
