Three upgrades from the on-glass rounds on .173/.221: - `ddc-open` timing: the handle-ACQUISITION cost per monitor is reported even when it yields no physical handles — the poller's first contact with a virtual display, exactly what the DDC-fail-fast driver work changes; the old code silently skipped handle-less monitors, which on a streaming host in exclusive topology is every monitor there is. - Monitors are labeled by GDI device name (\\.\DISPLAYn) so a virtual display and a panel are tellable apart in the correlation log. - `extend` mode: one SDC_TOPOLOGY_EXTEND poke — re-activates every attachable display, i.e. the exact 'non-managed display re-activated' event the exclusive watchdog evicts. One shot, not a loop: trigger a reassert round, observe the recovery. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
