- listeners() and rawListeners() in TypeScript of an event that no literal emit or listener gives a tuple (one registered only under computed names) read the untyped array, so each returned listener takes every argument a call passes. The array was checked into zero-argument functions, which called the listener without its arguments. - A typed 'newListener' or 'removeListener' listener in a program with a checked-dynamic listener of the other meta event registers through the adapter. The meta lowering's check looked only at the listener's own event and refused it with SC2020.
node-types fixture
A project whose node_modules contains @types/node — the adoption path for real-world Node/TypeScript projects. The vendored node_modules are COMMITTED TEST DATA, pinned so the type surface (and therefore the pinned diagnostics) never drifts with the registry:
@types/node24.13.3undici-types7.18.2 (its dependency — declares the web-platform globals: fetch/Response/AbortSignal/ReadableStream/...)
What the fixture pins (see tests/harness/project-config.test.ts):
argv-env.ts— the SUPPORTED process surface (argv, env) typed by @types/node lowers statically and the binary runs: with @types/node present, the shipped fallback declarations forprocess/node:fs/consolestand down (their types come from @types/node), but the same members lower to the same libCalls, recognized by name + @types/node provenance.fenced.ts— surface @types/node DECLARES but scriptc does not lower (process.uptime, Buffer.from, setInterval) reports the SC2020-family fence naming @types/node, instead of typechecking its way into a broken binary — and never a raw "Cannot find name" error.event-loop-metrics.tsandtimeout-type.ts— performance.eventLoopUtilization, monitorEventLoopDelay's IntervalHistogram and NodeJS.Timeout as declared types lower under @types/node exactly as under the fallback declarations.source-import/— an imported TypeScript source may use theRequestInfoglobal supplied by TypeScript's default DOM lib while scriptc adopts the project's @types/node declarations.
Projects WITHOUT @types/node (every other fixture and the whole corpus) keep the shipped fallback declarations and behave exactly as before.
