OverExposureFileSystem

The subset of file-system operations the language-service host needs. Injecting this (rather than always using typescript’s sys) lets tests drive the analyzer against in-memory sources with no real file-system access.

Import:

import type { OverExposureFileSystem } from '@mnaoumov/typescript-dev-toolkit/linters/over-exposure';

Signature:

export interface OverExposureFileSystem
