  "note": "The one Punjab science file extracted as native digital text rather than OCR, which makes its headline finding secure: zero religious tokens in the whole book, the cleanest A1 of 1 in the corpus - not even the bismillah the other Punjab science volumes carry survives in the extraction. Twelve chapters, sharing only about four titles with the Sindh and KP class-7 books, which are otherwise the same twelve-chapter book as each other; Punjab adds Immunity and Diseases, Chemical Bonds, Solutions and Technology in Everyday Life and drops the Water chapter both other boards give a full unit. Activity density is among the highest in the corpus at 66 activities. A7 is 5 on absence - one female-marked token in 41,060 words, a figure too small to interpret as a ratio. Beyond A1 and A7 the social lenses did not examine this volume, and nothing further about it is established.",
