Two mechanisms, both live-verified (register row AD-108 updated to match):
1. RESOLUTION. The player/house icons (0x100001ED/0x100001EE) are authored
as nested dat children of m_pMap (0x100001EC), itself a Type-1 button
whose UiButton.ConsumesDatChildren swallows them at build. The old
ResolveSwallowedIcon re-imported them standalone via
ImportInfos(hostLayout, iconId) — which returns null on the live DAT:
FindDesc walks the raw top-level Elements table (one entry for
0x2100006E) and never reaches them. Their ElementInfos only materialize
inside the full panel-slot resolve (ImportInfos(0x2100006E, 0x1000018C))
that MountMapHousePanel already imports — the pageInfo Bind already
receives. The fix finds each icon's info under m_pMap's own resolved
info subtree and BUILDS it through the new Bindings.IconBuilder seam
(production: LayoutImporter.Build under the DAT lock — the build half
of RowTemplateResolver's shape). An icon the normal walk DID build is
preferred (FindDescendant first), so a future ConsumesDatChildren
policy change cannot double-build.
2. POSITION. Found by this fix's own F1 live verification: the resolved
ring rendered pinned to m_pMap's top-left. PlaceMarker owns marker
position outright (retail's gmMapUI::Update re-places every tick;
retail's UpdateForParentSizeChange runs only on real parent resize),
but acdream re-runs ApplyAnchor per frame and the icon's compatibility
anchor had captured the authored (0,0) rect while the panel was still
hidden, re-asserting it over PlaceMarker's writes every frame.
PrepareIcon now sets Anchors=None (clearing any imported LayoutPolicy),
the established runtime-positioned-element convention.
Live numeric gate (session character +Acdream, cell 0xF07E003F):
independent computation (gid_to_lcoord -> display (90.8E, 0.5S) ->
byte-decoded PlaceMarkerOnMap formula, 17x16 icon, marker area
(6,8)-(247,258)) predicts local pixel (226,125); the connected client's
UI-tree dump shows the icon at screen (1166,195) under m_pMap (940,70) =
local (226,125) — exact match in both panel-open dumps. Coordinate text
"0.5S,90.8E", Holtburg town-marker tooltip (real-mouse hover), and the
House tab's "You may buy another house immediately." sentence all
confirmed on screen; ACE-confirmed graceful logout.
New pin: MapHousePanelLiveDatMountTests ([InstalledDatFact]) reproduces
the production mount recipe against the installed DATs — the test that
would have caught this at Batch C: pins the cold-import null, the
panel-slot resolution of both icons with non-degenerate extents, AND
that PlaceMarker's writes survive the per-frame ApplyAnchor pass.
Gates: Release build green; App suite (live-DAT mode) 5479/3 skips
(baseline 5478 + the new pin); Runtime 1744/0; full solution green.
