# Trim only the outer padding before the database suffix is appended.

# dev-prod-db-path.test.sh — assert the root Makefile's `dev-prod-db` target
# exports the same production database path the launcher would resolve on its
# own: an environment-provided KANDEV_DATABASE_PATH wins, then KANDEV_HOME_DIR,
# then $HOME/.kandev (resolveDatabasePath/resolveHomeDir in
# apps/backend/internal/launcher/constants.go).
#
# The pre-fix target assigned with `:=`, which outranks the environment in GNU
# Make. On an install whose KANDEV_HOME_DIR points outside $HOME, that silently
# pointed dev mode at the untouched $HOME/.kandev default while the launcher
# still printed "backed up production db", so the warning named a database the
# run never opened.
#
# Each case is a dry run. `-n` alone is not enough: make executes any recipe
# line mentioning $(MAKE) even under -n, so `@$(MAKE) dev` would recurse into a
# real build. Overriding MAKE swaps that line for a probe that prints the
# exported value and swallows the leftover `dev` argument on a `:` builtin. That
# neutralises the recursion and asserts the variable as the child process
# actually receives it rather than as the sibling echo renders it. `:` is used
# rather than a trailing `#` so the value carries nothing a make implementation
# might re-read as a comment.
