Live-DAT probe confirming the desk-verified facts before implementation:
host 0x2100006E slot 0x1000018C carries panelId 16 (gmMapUI::PostInit
signature children 0x100001EB-EF; gmHouseUI's ListBox 0x100001E6),
tabTableCount=2 with Map (button 0x100001F3 -> page 0x100001F6) as the
authored default and House (0x100001F4 -> 0x100001F7) second, close button
0x100001F5. Toolbar button 0x1000019A carries the matching panelId 16 —
the Map/House entry among the toolbar's three ghosted buttons. m_pMap's
own marker-area rect is (6,8)-(247,258); its hotspot template attrs
(0x47/0x48) resolve to element 0x100001F0 in LayoutDesc 0x21000026, a
10x10 Type-1 button with 3 states. The House ListBox authors exactly one
row template (LayoutDesc 0x21000025 element 0x100001E7, a bare
UIElement_Text row, no scrollbar) and zero static child rows — the box is
genuinely empty until the first server notice, refuting the recon's
"authored default content" hypothesis for the no-house case.
Kept as a permanent env-gated pin (ACDREAM_PROBE_LIVE_MOUNT=1), matching
FaPanelSlotProbeTests' precedent.
