- Destructuring an `any` value in TypeScript (a function typed `any`, an awaited `any`, `JSON.parse`, an `any` table read) now goes through the checked-dynamic value, as JavaScript sources and #1407's JS-declared results already did. Object sources get V8's RequireObjectCoercible TypeError for the spellings the assignment form reproduces. - A method call or member read on a checker-`any` receiver whose value is a fresh typed call result (`out.split("\n").map(...)`, `.pop()`, `.length`) boxes that temporary and dispatches on the runtime kind, only after every other lowering declined. - `const { a, b: c } = ns` and `= await import("./m")` over a program module bind each export the way `ns.a` reads it. - A defaulted parameter of a program-source function, arrow or function expression that the checker types `any` (a default under an `(...args: any[]) => any` wrapper slot, where the contextual `any` wins) is a dyn ABI slot in the callable's type. - An async lambda whose signature answered a bare dyn result (a library slot `A | Promise<A>` with A = any) produces Promise<unknown>. - `761-any-objects` compiles and moves back to the corpus; the retired-engine 2083/2104 snapshots shrink to their remaining fences. - JavaScript `Promise.resolve(value)` (in a JavaScript file) over a dyn value holding a promise answers that promise instead of wrapping it, so a TypeScript async callback's result is adopted by JavaScript retry helpers.
