Saves the overnight-round recon (embedded findings + this session's desk
verification) for auditability before implementation starts. Corrects two
handoff claims: the panel id is 16 (already resolved by the existing FA
campaign's full 16-slot gmPanelUI::SetupChildren dump, not a guess from
{1,2,6,14}), and GameEventType already defines all four House opcodes
(0x0225-0x0228) — what's missing is routing, not the enum. Identifies that
LandDefs.GidToLcoord/LcoordToGid (src/AcDream.Core/Physics/LandDefs.cs) is
an existing tested port of LandDefs::gid_to_lcoord, reusable for both the
Map tab's coordinate math and the House location display — no re-port
needed. Cites the toolbar button (0x1000019A, panel id 16), the 53-entry
s_rgLocations marker table verbatim, the ServerPosition wire struct reuse
for HouseData.Position, and the AuthoredTooltipText/RetailTooltipPresenter
seam that will close register row TS-85's last item (gmMapUI::AddMapNote).
