The opening episode's subsidized year churned across three names in typescript…

This is a renaming: the same material survives, but names or labels changed between draft and print.

In the manuscript. "Another typescript has the year of this episode taking place in the Year of the Perdue Wonderchicken," which is "scratched out and then the Year of the Trial-Size Dove Bar is inked in and then, that is scratched out and finally the Year of the Tuck's Medicated Pad is written in and that is what appears in the final text" Riles's firsthand archive account — "this episode" = the then-opening professional-conversationalist scene

In the published book. Scene 5 (pp. 27–31)

Evidence. A single source reports this. But generically consonant with the diff-name-changes record that several subsidized-year labels shifted in draft (per Steven Moore's first-draft collation); print side confirmed at the catalog grain (scene 5 is catalog-dated YTMP; the scene text itself names no year). Documented by Riles's firsthand archive account (firsthand HRC sighting).

Further notes. All three names belong to the published Subsidized-Time sequence (the p. 223 year list, scene 59), so the churn reads as the episode being re-dated within the era rather than year-names being invented — though with Moore's testimony that the labels themselves shifted (Twinkie→Whopper), dating-churn vs label-churn cannot be fully separated without the HRC pages. More composition-level chronology instability for the YDAU-dating debates to weigh (see diff-name-changes notes). Gated on eventual HRC text access.
