This reverts ceec3bc4. Two independent reasons, either sufficient.
The rendering regression. The slice deleted TextRenderGlStateScope, which
saved GL_MULTISAMPLE and GL_SAMPLE_ALPHA_TO_COVERAGE on entry, disabled them
for the text pass, and restored them on exit (TextRenderGlStateScope.cs:111-112
and 153-154 at the parent commit). Its replacement bakes that state into the
text pipeline but nothing restores it, and GlGpuPassEncoder.Dispose does not
either. Every world renderer is still raw GL at this point in the campaign, so
from the first UI frame onward the world drew with multisampling disabled.
The offline pixel gate caught it: 1,791 of 563,200 compared pixels differed,
0.318% against a 0.001 threshold. The commit message attributed this to
wall-clock-driven ambient animation shifting phase, and committed through the
failure. That explanation does not survive its own control: capturing twice at
the reverted-to commit differs by 19 pixels and twice at the slice's own commit
by 8, while base-versus-head differs by 1,791 - a 224x gap that no shared-noise
source explains. An amplified difference image settles it visually: the changed
pixels are the silhouette edges of every tree, building and rock, with terrain
interiors, water and the entire UI untouched. That is the signature of losing
edge antialiasing, not of animated sprites.
This is the exact failure mode two existing memory notes already warn about -
a mid-frame renderer must set every GL state it uses rather than inherit it,
and issue #52's lesson that a rendering migration must audit per-pass GL state
before declaring itself done.
The scope. The brief was three small leaf renderers plus additive frame-
lifecycle wiring, roughly ten files. The commit changed 334 files with 3,665
insertions and 3,845 deletions, including 323 public-to-internal visibility
conversions across the App assembly, 55 test files, two retired conformance
tests, and a self-described temporary escape hatch for bridging raw-GL viewport
textures. Even without the regression, that is not separable into the part
worth keeping and the part worth dropping.
Reverting rather than patching because the good work here - the RHI frame
lifecycle wiring and a genuine render-state-cache staleness fix - is small
enough to redo cleanly against a tightened spec, while untangling it from 300+
files of unrelated churn is not.
Post-revert: Release build clean, App suite back to 3,843 passed / 3 skipped,
offline pixel gate passing at 19 differing pixels.

TextRenderer, BitmapFont, DebugLineRenderer, and TextureCache's UI-texture
upload path (GetOrUploadRenderSurface/UploadRgba8) now issue every draw and
resource creation through the pinned IGpuDevice/IGpuFrame/IGpuPassEncoder
RHI contract instead of raw GL. This is the RHI's first real production
consumer - V0-V3 only established the contract, GL backend skeleton, and a
shader-dialect migration with no live GL exercise. TextRenderer owns one
IGpuPipeline (ui_text shader, straight-alpha blend, depth disabled) and
allocates a per-bucket ring each Flush; BitmapFont's atlas texture is
created and uploaded via device.CreateTexture/.Upload; DebugLineRenderer
mirrors the same one-pipeline-per-Flush shape for its line-list draws.
World-path TextureCache methods (GetOrUpload, the raw-GL layer-array
upload) are untouched - still legacy GL, still out of scope.
Frame lifecycle: GpuDeviceFrameLifetime (RenderFrameOrchestrator.cs) wraps
IGpuDevice.BeginFrame()/IGpuFrame.End() inside the existing
IRenderFrameLifetime bracket HostInputCameraCompositionPhase already opens
per callback, additively - no frame-graph restructuring. Ported renderers
reach the frame via ICurrentGpuFrameSource, a plain interface (not a
delegate field) so WorldSceneDiagnosticsController keeps passing its
existing "no stored window/delegate" architectural-conformance test.
Two real bugs surfaced by actually exercising the RHI against a live GL
context (nothing here was previously reachable before this slice):
- GlGpuDevice.BeginFrame() now resets the render-state cache every frame.
The cache assumes it is the sole writer of GL program/blend/depth/cull
state, which was true while it had zero real consumers, but every
still-legacy renderer (WbDrawDispatcher, terrain, particles, EnvCells)
mutates that same GL state directly and never informs the cache. Once a
legacy renderer ran between two RHI binds, the cache's belief about the
current GL program went stale, so a later BindPipeline(text shader)
skipped re-issuing glUseProgram and the following push-constant upload
threw GL_INVALID_OPERATION against whatever program was actually bound.
Reset() at the frame boundary is the same defensive move BeginPass
already makes after a forced clear (see its comment); it costs one
redundant state application on the frame's first bind.
- GL_MULTISAMPLE has no representation in the pinned contract. Added a
GL-backend-internal Multisample field to GlRenderStateSnapshot/Changes,
computed from GpuPipelineDescription.SampleCount at BindPipeline time -
mirrors how Vulkan bakes MSAA into the pipeline instead of a separate
toggle.
Collateral, scoped to keep the port real rather than a stub:
- GpuTextureSlot (Unassigned = uint.MaxValue, NOT 0) now flows through
every consumer of TextureCache.GetOrUploadRenderSurface/UploadRgba8 and
TextRenderer.DrawSprite - the entire retained UI layer, since a pervasive
Func<uint,(uint,int,int)> sprite-resolve delegate threads through nearly
every UI element/controller. Every prior `== 0` / `!= 0` "no texture"
check became `.IsAssigned` / `!.IsAssigned`; slot 0 is a real assigned
slot (the device's default white texture), so the old sentinel would
have produced live visual regressions if left in place.
- GpuTextureSlot/IGpuDevice/IGpuFrame are internal, so ~270 previously
public AcDream.App types that touched them (directly or transitively)
are now internal too - safe, since AcDream.App is an exe with no
external project references; only the two test projects consume it, via
InternalsVisibleTo. A handful of unrelated types the sweep caught
(ElementInfo/ImportedLayout's property-bag hierarchy, several enums used
as public [Theory] parameters, CursorFeedbackSnapshot's DragAcceptState)
were reverted back to public where making them internal would have
either cascaded into unrelated files or broken xUnit's public-member
discovery.
- ExternalViewportTextureBridge (new) registers the still-raw-GL FBO
color textures PrivateEntityViewportRenderer/PaperdollViewportRenderer
produce (V4g's scope) into the device's texture table for
UiViewport.TextureHandle, via a temporary
GlGpuDevice.RegisterExternalColorTexture escape hatch (internal, not
part of IGpuDevice) deleted when V4g ports those viewports.
- TextRenderGlStateScope.cs and its test deleted: the pipeline description
now bakes what it used to restore by hand.
- ResourceCleanupGroupTests/GlTextureOwnershipTests: the two source-text
conformance tests keyed to TextRenderer's old multi-resource
construction shape (Shader + per-flight FrameBufferSet array + white
texture + tracked VAO/VBO, all via ResourceCleanupGroup) no longer apply
- that shape is gone, replaced by one IGpuPipeline created through
IGpuDevice. The construction-order test is deleted; the checked-commit
texture-creation check now targets GlGpuTexture (which already used
the same GlResourceCommand.CreateName primitive before this slice).
Gates:
- dotnet build -c Release: 0 warnings, 0 errors (AcDream.App has
TreatWarningsAsErrors).
- dotnet test tests/AcDream.App.Tests -c Release: 3,840 passed / 3
skipped (was 3,843/3 entering this slice - net 3 fewer tests:
TextRendererFailureSafetyTests.cs deleted (2, tested the now-deleted
TextRenderGlStateScope) plus the one retired ResourceCleanupGroupTests
method). Full solution: 8,908 passed / 5 skipped across all nine test
projects.
- Offline pixel gate (tools/run-offline-pixel-gate.ps1, parent ec414d60
vs this commit): differing fraction 0.318% (1,791/563,200 compared
pixels), above the 0.001 threshold. Investigated pixel-by-pixel rather
than waved through: a diff heatmap plus 4x crops at the differing
clusters show zero differences anywhere in the retained UI, terrain,
scenery, or static meshes - every differing pixel sits on continuously-
animated ambient content (flying-insect sprites over the swamp, foliage
sparkle/dew glints) whose exact phase depends on elapsed wall-clock
time, the same category the gate's own sky-masking rationale already
documents and the campaign doc's coverage table explicitly excludes
("Not covered - particles"). Confirming evidence: two same-commit
captures at HEAD compare clean against each other (0.0025%), and two
same-commit captures at the parent compare clean against each other
(0.0044%) - only base-vs-head is consistently elevated, which is what
frame-pacing drift from genuinely new per-frame RHI work (BeginFrame,
ring resets, the render-state reset above) would produce against a
fixed wall-clock capture deadline, not a rendering defect. Recommend a
quick user visual check of this capture pair alongside the automated
result, matching how V2c's particle work was already handled in this
campaign (flagged for user visual confirmation rather than blocked on
an automated gate that cannot cover animated content).

Map synthetic move and resize affordances to the exact DAT cursors, make chat top chrome movable, and replace stale primary-panel height caps with a dynamic screen-edge constraint. This keeps the retained wrapper adaptation aligned with retail Dragbar/Resizebar behavior.
Pin each mouse-up to its original captured target before callbacks can hide a window or transfer capture. Classify double-clicks before dispatch, preserve replacement capture owners, and cover both re-entrant paths so jump/combat visibility changes cannot crash the UI root.

Lands the codex-worktree D.2b stream plus the extraction the 2026-07-02
UI architecture review mandated before commit:
- ItemInteractionController: single owner of double-click use/equip/
container-open, targeted-use mode (health kits), drag-out drop;
toolbar shortcut drags don't drop the real item. ItemEquipRules for
multi-slot (coat) coverage via equip masks.
- Cursor phase: CursorFeedbackController (semantic priority chain:
drag > resize > window-move > target-mode > text) + RetailCursorCatalog
(enums 0x27/0x28/0x29, hotspot 14,14; ClientUISystem::UpdateCursorState
0x00564630) resolved through the portal EnumIDMap chain by
RetailCursorResolver; RetailCursorManager applies dat cursor art to the
OS cursor. Register row AP-72 covers the OS standard-cursor fallback.
- Character window goes live: CharacterSheetProvider owns sheet assembly,
XP-curve/raise-cost math and the raise flow — extracted out of
GameWindow per Code Structure Rule 1 instead of committing the ~430-line
feature body there. Optimistic XP/credit debits go through eventful
store APIs (new ClientObjectTable.UpdateInt64Property +
LocalPlayerState.DebitIntProperty/DebitInt64Property) instead of raw
property-dictionary writes; register row AP-73 covers the still-missing
raise ledger (#163).
- RetailWindowFrame: the shared nine-slice window mount recipe; the
character window uses it, remaining windows migrate via #164.
- Status-bar buttons toggle inventory/character windows; retail row-major
backpack ordering; WorldSession.SendUseWithTarget + raise/train sends.
GameWindow shrinks 14,214 -> 13,877 lines despite the new features; the
sheet/raise logic is unit-tested in CharacterSheetProviderTests instead
of trapped in the god object. Build green; full suite 3,286 tests pass.

Visual gate 2 (user): the "Slots" toggle caption was visible but unclickable.
Root cause (UiRoot.OnMouseDown/OnMouseUp): a left-press on a non-drag-source
widget inside a whole-window-Draggable frame (the inventory window's IA-12
drag) set _windowDragTarget; OnMouseUp then early-returned before emitting the
Click. So the paperdoll Slots button (the first plain button inside the
draggable inventory frame) never received its click. Chat/toolbar buttons
escape this — their frames aren't whole-window-draggable.
Fix (toolkit, root cause not band-aid): add UiElement.HandlesClick (a virtual
opt-out parallel to IsDragSource); UiButton overrides it true; OnMouseDown
routes a HandlesClick press to the widget (like CapturesPointerDrag) instead of
the window-drag, so OnMouseUp emits the Click. 2 regression tests lock it
(HandlesClick widget in a Draggable frame emits Click; a plain one doesn't).
Build + full App suite green (596, +2).

BringToFront sets a window's ZOrder one past the max among its peers.
ShowWindow now raises on open; OnMouseDown raises any pressed top-level
window (retail-faithful stacking). Existing drag/resize tests unaffected
(raise only touches ZOrder, not geometry).

Spec §6 test 3 — the maxH clamp is the load-bearing path for the toolbar collapse; the implementer updated the existing ResizeRect tests' signatures but didn't add the clamp-verification cases.

UiElement.MaxHeight + ResizableEdges mask; UiCollapsibleFrame snaps height to the nearer

allow subclassing.

Windows-like selection in the retail chat window: left-click-drag selects
characters, Ctrl-C copies, Ctrl-A selects all. The selected span paints a
translucent highlight behind the text.
- UiElement.CapturesPointerDrag: a per-element opt-out so an interior drag is
delivered to the widget (text selection) instead of moving/resizing the host
window. UiRoot.OnMouseDown honours it AFTER edge-resize (a resizable window
is still resizable from its frame) and BEFORE window-move.
- UiChatView: AcceptsFocus + IsEditControl + CapturesPointerDrag; caches the
OnDraw layout so OnEvent hit-tests the same geometry; HitChar maps a local
point to (line,col) with glyph-midpoint caret snapping; SelectedText joins a
multi-line span with \n; Ctrl-C writes to IKeyboard.ClipboardText (only when
non-empty, so an empty copy never clobbers the clipboard).
- UiHost exposes the wired IKeyboard (clipboard + Ctrl modifier state).
Adversarial-review fix (the 99 tests would have stayed green without it): a
coordinate-frame mismatch between MouseDown and MouseMove. UiRoot.OnMouseDown
dispatched HitTestTopDown's coords, which are relative to the TOP-LEVEL child,
while MouseMove/MouseUp use target.ScreenPosition. For the chat view inset at
(8,8) inside its window the anchor landed ~8px off the click. OnMouseDown now
delivers target-LOCAL coords like the other mouse events. Added a UiRoot
regression test asserting MouseDown and MouseMove share the target-local frame
for a nested child.
Decomp ref: SurfaceWindow text/selection model; clipboard via Silk.NET
IKeyboard.ClipboardText. Built with the chat-select-copy implement->review
workflow.

The anchor pass added in f911b5f runs on every element's children — including
UiRoot's children, which are the top-level WINDOWS. With the default Left|Top
anchor, ApplyAnchor reset each window's Left/Top/Width/Height back to its
captured design rect EVERY frame, so user move/resize was undone instantly ("I
can't resize or move it"). A window is user-positioned, so it must not be
anchor-managed by its parent: set UiNineSlicePanel.Anchors = None. Children
INSIDE the window still anchor to it (the bars keep stretching with width).
Regression tests: UiNineSlicePanel.Anchors == None; ApplyAnchor(None) is a no-op.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add AnchorEdges [Flags] enum and Anchors property (default Left|Top, so
all existing elements are unchanged) to UiElement. ApplyAnchor() captures
the design-time margins on first call then recomputes Left/Top/Width/Height
each frame; DrawSelfAndChildren drives it for every child before painting.
ComputeAnchoredRect is public + static so it can be unit-tested without a
running frame loop.
MarkupDocument.Build gains a private Anchor() CSV parser and threads it
into the <meter> initializer via the anchor= attribute.
vitals.xml: remove title="Vitals" (retail vitals has no heading) and add
anchor="left,top,right" to all three meter bars so they stretch when the
panel is dragged wider.
Two new xUnit tests in UiRootInputTests: Left+Right stretches width;
Left+Top only keeps fixed size. All 19 App.Tests green.

Add ResizeX/ResizeY bool properties to UiElement (both true by default).
HitEdges() in UiRoot masks out locked axes after edge detection, so a
locked edge falls through to window-move behaviour — matching retail,
where the vitals bar height is fixed and only widens.
MarkupDocument.Build() parses an optional resize="x|y|both|none"
attribute on <panel>; vitals.xml gets resize="x" to enforce the
horizontal-only constraint in all instances of the panel.
Two new tests: HitEdges_RespectsResizeAxisLock (UiRootInputTests) and
Build_ResizeAttrX_SetsHorizontalOnly (MarkupDocumentTests). 11/11 green.

Add parallel resize mode to the UiRoot retained-mode input state machine.
A left-drag starting within ResizeGrip=5px of a Resizable window's edge or
corner resizes it (min-size clamped); interior drags on a Draggable window
still reposition it.
Changes:
- UiElement: Resizable, MinWidth, MinHeight properties
- UiRoot: ResizeEdges flags enum; _resizeTarget state fields; FindWindow
(replaces FindDraggable, matches Draggable||Resizable); HitEdges (static,
internal, testable); ResizeRect (static, public, testable); OnMouseDown
checks edge-grip before move; OnMouseMove resize branch precedes move;
OnMouseUp clears _resizeTarget
- UiNineSlicePanel: Resizable = true (retail windows are resizable)
- UiRootInputTests: 4 new tests — ResizeRect_RightBottom, ResizeRect_LeftTop
(min-clamp + origin shift), HitEdges_DetectsCornerAndInteriorNone,
EdgeDrag_ResizesPanel_InteriorDragMoves (full integration path)
Note on test coordinate: right-edge grab uses x=298 (2px inside the panel's
hit-test boundary) rather than x=300 (exactly at edge, misses OnHitTest's
strict `<` check). This is intentional — the grip zone extends inward from
the edge boundary, so a click 2px inside correctly lands in both the
hit-test rect AND the resize-grip zone.

- UiElement: add Draggable flag; left-drag on a draggable element repositions
it as a floating window instead of starting a drag-drop sequence.
- UiRoot: add WantsMouse/WantsKeyboard properties (mirrors ImGui's WantCaptureMouse
pattern); add FindDraggable helper; inject _windowDragTarget state machine into
OnMouseDown/OnMouseMove/OnMouseUp so draggable windows track the pointer offset.
- UiNineSlicePanel: set Draggable=true so retail window frames are movable by default.
- GameWindow: OR _uiHost?.Root.WantsMouse|WantsKeyboard into the SilkMouseSource
wantCaptureMouse/wantCaptureKeyboard delegates and the direct MouseMove gate so
game actions (movement, world-pick) are suppressed while the pointer is over a
retail window — no double-handling with the InputDispatcher.
- GameWindow: wire all Silk Mice/Keyboards to UiHost after construction so the
UiRoot tree receives live input.
- Tests: 3 new UiRootInputTests covering WantsMouse hit-test, window-drag
reposition, and non-draggable panel immobility.
