+`0x10000180` + 5px = 310×372), so its authored 0x3C..0x3F values are
+already chrome-INCLUSIVE. Adding the NineSlice wrapper's own 10px inset
+on top double-counted the bevel, clamping MinWidth to 320 while the

+(chrome inset = 0 for constraint resolution when set — the value stays
+DAT-sourced, only the redundant inset is skipped); `MountCharacter` sets
+it true. The mounted outer clamps are now EXACTLY what the host authors:

+Titles page alone is 300×575, plus the 25px tab bar). That 600 is a real
+authored canvas, but it is the CONTENT's own design surface, not the
+mounted default — retail scroll-clips it into the shared host's much
+smaller 300×362 content parent (`0x10000180`). Pre-fix, `MountCharacter`
+left `ContentHeight` unset, so it fell back to the raw 600px canvas,

+was never retail's actual opening size. **372 (the host's own outer
+frame, 362 content + 10 chrome) is the number that governs the mount
+default** — it is also exactly the host's own authored MinHeight, so
+retail's Character/Skills window opens AT its resize floor and can only
+be dragged taller, never shorter. `MountCharacter` now sets

+**CORRECTED (CT6 fix round, BLOCKER B1, 2026-08-25):** this section
+originally claimed the NineSlice chrome inset (`2 *
+RetailChromeSprites.Border` = 10px) "is added automatically by
+`RetailWindowFrame.ResolveConstraint`, giving the mounted outer frame
+MinWidth=MaxWidth=320, MinHeight=382, MaxHeight=1010." That was WRONG.
+Host `0x100005FE` is not a bare content element our own NineSlice
+wrapper adds chrome to — per the geometry dumped above, it IS retail's
+own complete outer window frame: 5px bevel + the 300×362 content parent
+(`0x10000180`) + 5px = 310×372 exactly. Its authored 0x3C..0x3F values
+are therefore already CHROME-INCLUSIVE. Composing the wrapper's own 10px
+inset on top of an already chrome-inclusive source double-counted the
+bevel: the mounted window's clamp said MinWidth=320 while its actual
+mounted outer width was only 310 — the window opened already violating
+its own minimum, silently "fixed" at runtime only because
+`RetailWindowManager.ResizeTo`'s main-panel geometry sync forcibly
+widened it to 320 despite `ResizeX=false`, which would have produced a
+visible 15px right-bevel seam against the other eight main panels
+sharing that sync.
+
+**Fix:** a new opt-out,
+`RetailWindowFrame.Options.DatConstraintSourceIsOuterFrame` (default
+`false`, preserving every other window's existing content-plus-chrome
+behavior), tells `ResolveConstraint` to apply a chrome inset of 0 when
+the DAT source is itself already the outer frame. `MountCharacter` sets
+it `true` for `hostConstraint`. The mounted outer clamps are now EXACTLY
+the host's four raw values, no composed arithmetic: **MinWidth=
+MaxWidth=310, MinHeight=372, MaxHeight=1000.** A new mount-time
+invariant in `RetailWindowFrame.Mount` (throws if the just-mounted outer
+extent falls outside its own just-computed clamp) guards against this
+class of bug recurring for any window this path mounts.
`ResizeX=false`/`ResizableEdges=Bottom` (already correct in the
pre-CT6 code) match the fixed-width/bottom-only-Resizebar authoring
exactly — no change needed there.
+### Which size governs the mount default (S4, campaign-lead ruling, 2026-08-25)
+
+The "Size tension" flagged earlier in this doc (§4, "Correction to the
+plan") — `0x2100002E`'s own root authored 300×600 vs. the host slot's
+300×362 — is now resolved: **372px outer (362px content) is the number
+that governs the MOUNTED DEFAULT**, and 600 is the content's own
+authored design canvas that retail scroll-clips into the much smaller
+host slot, never the size the window actually opens at. Concretely:
+`0x2100002E`'s 300×600 root exists because its Titles page alone is
+authored 300×575 (Y=25 offset + the 25px tab bar — §3 above) — that is
+real, authored geometry, and the Titles page correctly stretches to fill
+whatever height the mounted window offers via its own `LayoutPolicy`
+(confirmed below). But retail never displays that full 600px canvas at
+once outside of the Titles tab's own internal scroll: the shared
+`gmPanelUI` host's content parent (`0x10000180`) is fixed at 300×362,
+and 372 (362 + the 10px chrome bevel) is exactly the host's own
+authored MinHeight — i.e., retail's Character/Skills window OPENS at
+its own resize floor and can only be dragged taller, never shorter.
+Pre-fix, `MountCharacter` left `Options.ContentHeight` unset, so it fell
+back to `content.Width`/`content.Height` — the raw 600px canvas — giving
+a stale 610px (600 + 10 chrome) mounted default that was never retail's
+actual opening size and was 238px taller than the true floor. Fixed by
+setting `Options.ContentHeight = 362f` explicitly (the same host
+content-parent height this section already probed and cited, not a new
+number). At the corrected 372px default, the authored page composition
+(header 112px + list 160px + divider + footer) is the true 362px design;
+the 9 attribute/vital rows (9 × 20 = 180px content) OVERFLOW the 160px
+list immediately, so the stat list's scrollbar is active from the moment
+the window opens — this is retail-correct (see §S2 below for what
+"active" means given the corrected `HideWhenDisabled` finding), not a
+regression introduced by the fix.

### Titles-page list reflow
The Titles page's own container (`0x10000539`) and its ListBox
(`0x10000532`) both already carry a REAL authored `LayoutPolicy` in the
committed/installed layout (live-verified: `LayoutPolicy is not null`
for both) that correctly stretches with the mounted content's height —
-no code was needed to make the PAGE itself reflow. The only missing
-piece was the ListBox's own compatibility fallback (`Anchors =
-Left|Top|Bottom`, engaged only when `LayoutPolicy is null` — a no-op on
-the real DAT, but needed for synthetic/test layouts and matches the
-identical pattern already used for `CharacterStatController`'s
-`statList`), added in `CharacterTitlesController.Bind`.

+
+**CORRECTED (CT6 fix round, S3, 2026-08-25):** this section originally
+went on to claim "the only missing piece was the ListBox's own
+compatibility fallback (`Anchors = Left|Top|Bottom`, engaged only when
+`LayoutPolicy is null` — a no-op on the real DAT, but needed for
+synthetic/test layouts...), added in `CharacterTitlesController.Bind`."
+That framing was wrong: both `0x10000532` and `0x10000539` author
+`HasOriginalParentSize=true` (the field `DatWidgetFactory` gates
+`LayoutPolicy` assignment on), confirmed both on the real installed DAT
+and the committed fixture — `LayoutImporter`/`DatWidgetFactory` ALWAYS
+assigns a real `LayoutPolicy` to these elements, so the `if
+(listBox.LayoutPolicy is null)` branch never ran anywhere, not even in

+
+### Correction to the scrollbar-visibility finding (S2, 2026-08-25)
+
+The CT6 landing notes (in the campaign plan ledger) claimed
+`UiScrollbar`'s own `IsPresentationVisible`/`IsModelDisabled` "already
+draw the correct full-track 'disabled' thumb when content fits
+(`HideWhenDisabled` defaults false)." That had the authored default
+BACKWARDS. Both `0x1000023E` (the shared Attributes/Skills list
+scrollbar) and `0x10000533` (the Titles list's own scrollbar) author
+property `0x79` (`HideWhenDisabled`) **TRUE** in the committed fixture —
+verified directly against `tests/AcDream.App.Tests/UI/Layout/fixtures/character_2100002E.json`,
+property `"121"` (=0x79) carries `"BoolValue": true` on both elements. A
+fitting list HIDES the bar entirely (`IsPresentationVisible` false); it
+does not leave a full-track "disabled" thumb on screen. The CODE in
+`CharacterStatController.RebuildActiveList` was already correct —
+`.Visible = true` only keeps the bar bound in the tree, and
+`IsPresentationVisible` is the actual show/hide computation — only the
+description was wrong. Given the S4 correction above (mount default is
+now the compact 372px floor), the practical consequence is: the stat
+list's scrollbar is VISIBLE and interactive from the moment the window
+opens (rows overflow at the default), and DISAPPEARS once the window is
+grown enough that all rows fit — the opposite of what the uncorrected
+description implied.
