The p. 171 phone-answer was trimmed one m: galley *Mmmyellow* → hardcover "Mmyellow" — while the novel kept BOTH spellings at other sites.

This is a revision: the same material was reworked in substance between draft and print.

In the galley proofs. The 1995 galley proofs: Mmmyellow at the p. 171 site.

In the published book. Scene 50 (pp. 169–171)

Evidence. A single source reports this.

Further notes. Audit finding preserved: the published text still reads "Mmmyellow" at pp. 32/242-area sites and "Mmyellow" at pp. 135/907-area sites — only the p. 171 instance changed, so the change normalized nothing; both spellings are canonical print. Do not "correct" either form when quoting.
