TSR0011

{0} (sound mode enables '{1}').

Sound mode turned on a strict-family compiler option and tsc's error for it fired. Fix what the wrapped tsc message describes.

Rule general: Escape hatches, pragmas and configuration. Reported by ts-r-check and ts-r-lsp in files that opt in to sound mode. See Sound mode.

What it means

Each sound-mode level forces the strict family of options for its files. When the tsconfig doesn't set the option named in {1} and only sound mode turns it on, tsc's diagnostic is reported with this TSR code and tsc's message in {0}. If the tsconfig already sets the option, tsc's own code is reported instead.

How to fix

  • Fix what the wrapped tsc message describes.
  • Or turn the option on in tsconfig.json, so the error keeps tsc's code and tsc reports it too.

Sound mode is defined in design record 0007 (accepted 2026-10-15).
