The tsc gate (preflight's errorsOf, and the original program of a JSX or declaration-projection build) asked for every file's semantic diagnostics, then dropped all of those in an opted-in package's files, in unselected package JavaScript and in package shims. With --npm-static that is nearly the whole check: on three.js's nodes fixture the 82 package files took 1.17 s and reported 13,022 diagnostics, the program's own files 0.1 s. getPreEmitDiagnostics takes the files whose diagnostics its caller keeps. When some file is left out, the server checks only the kept files (getDiagnosticsOfCheckedFiles), and their semantic diagnostics come in the full check's order. When a stored answer for the supplied declaration files applies to the program, it stands in for checking those files, as in the full check; the storage rule is unchanged. A global diagnostic can come from checking any file, so when the partial check reports one, the full check answers as before. At load time, before workspace packages are known, the gate leaves out only package and shim files. The kept diagnostics are unchanged.
