# DEBUG=0 COMPACT=1 is a release build: it defines FURI_NDEBUG, not FURI_DEBUG,
# and `furi_assert` is gated on `#ifdef FURI_DEBUG` (furi/core/check.h:77), so it
# compiles to nothing. (NDEBUG is not the switch — fbt defines NDEBUG in every
# configuration, DEBUG=1 included.) Both build paths here are release builds, so
# there is no configuration in this repo where an assert survives. Use
# `furi_check` (or an explicit `if`) for anything that has to hold in production.
