# Tests for scripts/remove.sh — interactive removal of rulesets-managed
# symlinks under ~/.claude/.
#
# Strategy (mirrors audit.bats): redirect HOME to a temp dir per test,
# scaffold ~/.claude/{skills,rules,hooks} with symlinks pointing at REAL
# repo files, run the real remove.sh against that synthetic ~/.claude/.
# remove.sh resolves the repo root from its own location, so the "managed"
# check compares against the real repo regardless of HOME.
