The scanner reported success. The file opens. Page 47 is not in it.
A double feed pulled two sheets through together. Nothing downstream flags it. Every page in the file is clean, so the file looks complete.
Page-sequence reconciliation catches it, and it runs before indexing: the declared total, the printed folio sequence, section continuity, internal cross-references, and physical evidence like staple holes or tab dividers.
Index first and the gap disappears, because an index describes what is present, and what is present looks whole.
