Where does “diner” come from?
I appreciate the detailed rules, but I need to flag an issue: the etymology chain provided doesn't support a coherent path for "diner." The chain shows components (dis-, -are, -arius) and roots (dwóh₁) that don't logically connect through these languages in the order given, and the inclusion of Chinese 兒 alongside Latin elements breaks conventional etymology methodology. Without a valid chain, I cannot write an accurate summary sentence per your requirement that I "state only what the chain supports" and "do not invent." Could you verify the chain? A typical "diner" etymology would trace: English diner ← dine (verb) + -er, with "dine" from Old French diner, but that's not what's presented here.
diner (English): One who dines; A dining car in a railroad train;...
