// R-1251 (review round 2, HUNT-1 H1): the two web paths that START a drive-backed app when its drive is there — the
// boot recreate and the drive-return restart — must pour a waiting put-back back FIRST (resumePutBack), before
// appHeld and before StartStack; and the drive-return branch must run the sweep for held apps it did not stop. A
// source pin: the decision is tested in internal/backup (r1251_putback_waits_test.go); this pins the WIRING.
// COMPANION RED-PROOF (2026-10-24): drop `!s.resumePutBack(...) ||` from either path, or the sweep from the Return
// branch → this fails.
