Book by Jonathan Clegg and Joshua Robinson (serialized by the Wall Street Journal)

Never retrieved by any phase. The single origin of the tracksuit anecdote, serialised in the Wall Street Journal; everything downstream is repetition-only, so this record stands alone and is not independent confirmation of itself (§13.4) — the claim register records `independentSourceIds: []` for the claim it supports. Unresolved conflict on its publication year: Phase 1 dates it 2022, Phase 5 dates it 2023 (Phase 8 Annex B, C-09); no publicationDate is asserted here rather than silently resolving that conflict. Phase 1 and Phase 5 each entered this book separately; the two records were merged here in unit 3.19 because they are the same source.
