# lib/tests/profile-default.test.sh — default profile (full) when nothing is
# selected: `current` is label-driven (BDR-030 — gstack starts off, so a
# parked count says nothing about which profile is on), `reset` lands on
# DEFAULT_PROFILE, `gstack off` resolves the default through active_profile(),
# and hooks/statusline.sh falls back to the same constant. Covers contract
# criteria 2/3/4/5. Hermetic: fixture repo via *_REPO_OVERRIDE + fake `claude`
# on PATH — same harness as profile-set-managed.test.sh.
