Round 3 of the field-reported exclusive-topology 0x57, with the reporter's retest logs finally separating the variable: the SAME isolate call converged rc=0 whenever a kept member already sat at (0,0), and failed 0x57 on every shape — doomed-path-carried AND keep-only escalation — whenever the doomed physical held the origin. A committable config must still contain a primary (a source pinned exactly at (0,0)); deactivating the display that held it while the kept virtual stays at its EXTEND offset supplies an origin-less desktop, which Windows rejects wholesale. Translate the kept sources rigidly so the top-left-most lands on the origin; sets already covering (0,0) are untouched so plain re-commits stay byte-identical. Also from the same logs: - restore_displays_ccd now guarantees the desk is never left all-dark: the saved snapshot can be unappliable (0x64a — it pinned a virtual target incarnation removed before teardown) or apply cleanly yet re-light nothing (snapshotted while an earlier failed teardown had the physicals off). If no external physical is active after the apply while one is connected, fall back to the database EXTEND preset. Internal panels don't count — a closed lid must not be forced back on. - the final isolate failure now names the surviving targets instead of asserting 'a non-virtual display stayed active' — the logs showed a sibling VIRTUAL display as the survivor (linger-expiry shrink), and the wording sent triage the wrong way.
