Add a black-box regression guard (8 tests in tests/init.test.cjs) asserting the init handlers (execute-phase, plan-phase, phase-op, milestone-op) resolve workstream-scoped planning paths under GSD_WORKSTREAM via planningPaths()/planningDir(), never the flat .planning form. Each positive case asserts both the scoped value and not-equal-to-flat (genuine guard, not coverage credit); fixtures seeded workstream-scoped; every CLI call pins GSD_WORKSTREAM and GSD_PROJECT for hermeticity. Verified by mutation (flat join fails exactly the 4 positive assertions) and re-verified under a polluted parent env. Test-only; src/ unmodified.
