public sealed class WorkerHostWhat a worker process does: answer import requests until the pipe closes.
No guide page documents this yet — the page shows what the code says about itself.
Remarks
The whole worker is this loop and one executor. It holds no cache, writes no sidecars and knows nothing about build plans — all of that stays in the coordinator, so there is one copy of it and a worker cannot disagree with the process that started it.
Its registry comes from BuiltInImporters, not from an argument. A worker with a different importer set produces different artefacts for the same file, and the disagreement surfaces as a cache that never hits — or as a build whose output depends on how many cores the machine has.
