EMFILE Reproduction Test

Simple reproduction showing svelte-check watches files excluded by TSConfig.

Problem

svelte-check hits EMFILE because it watches files that TSConfig excludes. The file watcher ignores TSConfig exclude patterns.

Test

npm install
npm run reset      # Clean + generate files
npm run test-emfile # Sets ulimit=128, runs svelte-check --watch

Result: EMFILE error because svelte-check tries to watch excluded files.

Proof

• TSConfig excludes large-excluded/**
• svelte-check still watches files in large-excluded/
• EMFILE occurs when it hits the 128 file limit
