Twin Discipline: How the Census Avoids Double-Counting

A census that counts papers can cheat without writing a false sentence: it can price the same exhibit twice, at two addresses, and let both pricings stand in the count as two results. My program's defence against that cheat is a rule, applied before it is admired — a census entry whose pricing already lives inside a published paper does not get a second paper — and this paper writes the rule as the corpus's accounting law, with its worked cases and its arithmetic printed where anyone can check them. The rule's founding application is the GAP-MAP's first section: Dead-End entries DE-11, DE-12, DE-13 and DE-17 are priced inside published papers — DE-11 in *Why Charge Comes in One Size*, §3; DE-12 and DE-13 in the strong-CP census papers; DE-17 in *The Clock-Ratio Census* — and under the rule they receive no papers of their own, so the named list as compiled totals 107 (63 published + 3 deposit-ready + 41 named and unwritten), where the maximal alternative, every remaining entry papered anyway, totals 111. The difference, exactly 4, is the rule's saving on that list, and it is printed in the map itself beside the count it corrects. The rule's second form governs twins: two attacks on one source paper at two addresses. CC-123 prices Saha 1920/21 at the stars-generally address while CC-56 priced Saha 1920 at the chromosphere address; CC-124 prices BCS 1957 with a bench CC-47 did not build. In both cases the later paper carries a twin disclosure on its face, names the earlier record's exhibits, and spends none of them as new — cross-reference only. Had both twins been double-spent, the named list would read 109 for zero new exhibits; the discipline's saving there is 2 papers and, more importantly, the exhibits' single counting. This paper states the law in three clauses — no second paper for a priced entry, no re-spent exhibit under a twin, one count for a shared paper — works each clause against its cases, including the hard case DE-23, whose paper *is* a Paper Map cell and is counted once, in one ledger only, and prints the law's own falsifiers: a single demonstrated double-count anywhere in the corpus re-opens the law's account on my side. Grade, printed at full size: ACCOUNTING LAW STATED AND VERIFIED ON ITS CASES — a law of the corpus's bookkeeping, deriving no physical result and counted as none.
