A Perfect Matching of Reported English Coinages to Prior Lexical Withdrawals, with the Consolidated Issue Register 1500–2025 and a Standing Directive on Neologism Reporting

English is reported to gain several hundred words a year. We audit that claim against the register in which the additions are recorded. Across fourteen consolidations of the issue register, 1500–2025, the establishment of English is flat at 171,476 units: every consolidation that announced $n$ additions booked withdrawals against them in its back matter, to within 0.03% of establishment. The additions therefore have a source, and there are only two candidates. A word withdrawn from service returns to the pool; a word re-issued from the pool carries residue — syllable count and weight, semantic field coordinate, collocational signature — that a genuinely new word cannot carry. Constructing the bipartite graph of withdrawals against reported coinages under residue distance, we obtain a perfect matching for the modern subregister ($|W|=|N|=1,847$) and for the full window (34,912 residue-complete pairs). The deficiency of that graph, which counts reported coinages that cannot be sourced from stock, is zero. Under 500 permutations of the residue assignment the maximum matching falls to $213\pm 19$. The annual coinage rate tracks the withdrawal rate lagged 57 years ($r=0.94$) and tracks cultural novelty at $r=0.03$. Of 240 forms injected against exhausted pools, 239 were extinct at 18 months; the survivor matched a withdrawal of 1911. Coinage is not observed. We issue a standing directive on the reporting of additions.
