T10 and T12 of the zero-cost compatibility plan, plus the maintainer decisions: - Programs that name Temporal type-check against TS 7's temporal lib (added only for them) and lower to Node 24's answers: typeof is "undefined", globalThis.Temporal is undefined, other uses throw ReferenceError at the root read. - node:v8 is importable; getHeapStatistics answers allocator-derived figures in Node's shape; other members fence with the by-design reason. vm's refusal says why. - node:stream/web exports the web stream globals themselves. - node:dns/promises and dns.promises: lookup and lookupService as promises, in the link-gated scr_dns_promises.c unit. - eval and the Function constructor throw Node's EvalError under --disallow-code-generation-from-strings; the corpus harness runs the Node oracle with that flag for `// @disallow-code-generation`. - graceful-fs is served as node:fs. Every new lowering replaces a refusal, and the new runtime code links only when used, so other programs compile to identical bytes (zero-cost gate).
