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).

Reduce GameWindow.OnUpdate to one typed orchestration call and remove transitive window callbacks from teardown, liveness, teleport placement, live presentation, auto-entry, and entity packet routing. Preserve the frozen retail object/network order while making the production owner graph explicit and testable.
Move local teleport, player-mode, animation, shadow, and sealed-dungeon lifetimes out of GameWindow. Make player-mode entry transactional and isolate approach completions by controller lifetime and approach generation so stale callbacks cannot affect replacements.

Make initial login and portal arrival consume one WorldRevealReadinessBarrier that joins near-tier mesh publication, destination composite uploads, and collision residency before normal world geometry becomes visible. This ports retail SmartBox's blocking-cell completion edge into the asynchronous client instead of exposing a ground-only login.
Add focused outdoor, indoor, texture, and invalid-claim tests; update the retail pseudocode, architecture, divergence record, issue ledger, roadmap baseline, and synchronized agent guidance.

Gate-2 fallout chain: session 1's bare-id wedge poisoned ACE's save (the
client reported garbage cells while walking through walls), so session 2
logged in with (cell=0xA9B4013F inn interior, pos=(91.4,32.7)) — a
position that cell does not contain. Probe evidence: exactly one
[cell-transit] line all session; the player free-fell into an empty
world. Two holes, both fixed at the root:
1. CellTransit pick escape hatch — restores the #83/A1.7 + #90
verification that lived in PhysicsEngine.ResolveCellId before the
collide-then-pick rewrite moved membership into
BuildCellSetAndPickContaining: an indoor current cell that IS
hydrated but whose CellBSP no longer overlaps ANY part of the foot
sphere is a bogus claim (corrupt save, or walked out through an
unblocked gap). The portal BFS can never reach an exit portal from a
cell the sphere isn't in, so no candidates exist and the claim held
forever — wedging collision (ShadowObjectRegistry's #98 gate reads
"indoor primary" -> outdoor object sweep skipped), wall BSP, terrain,
and the render root. The pick now demotes to the outdoor column under
the sphere centre (the LandDefs.AdjustToOutside result already
computed for the pick — cross-block safe). Sphere-overlap
(BSPQuery.SphereIntersectsCellBsp, pseudo_c:317666 -> :323267), NOT
point-in: doorway push-back leaves the centre a few cm outside while
the sphere still overlaps — no demotion, #90's ping-pong stays dead.
An unhydrated cell cannot be verified — stale beats null while
streaming hydrates (retail-equivalent: stale curr_cell kept when the
pick finds nothing).
2. PlayerModeAutoEntry spawn-ground hold — player-mode entry now waits
for the terrain under the spawn position to stream in
(isSpawnGroundReady predicate, K.2 pattern). Entering earlier
integrates gravity against an empty world: indoor-claimed spawns got
no floor from any source and free-fell into the void; outdoor spawns
raced hydration by ~1s every login. Retail never has this state (it
loads cells synchronously) — the hold is the async-streaming
equivalent of that invariant. With the hold, the entry snap
(Resolve, stepUp=100) runs against hydrated cell floors + terrain
and re-seats a corrupt save's claim immediately.
Tests: IndoorSeed_SphereFullyOutsideHydratedCell_DemotesToOutdoorColumn
(the gate-2 wedge shape, red pre-fix), straddle + no-BSP guards (the #90
hysteresis and stale-beats-null), TryEnter_Armed_SpawnGroundNotReady_
DoesNotFire. Full suite: 294+218+420 green; Core 1375 green + the same
4 pre-existing door/#99-era failures + 1 skip.

Five changes:
1. PlayerModeAutoEntry — testable guard class that fires once after
EnterWorld + WorldSession.State.InWorld + player entity present +
PlayerController.State == InWorld. GameWindow arms the entry
after EnterWorld; per-frame Tick checks all four guards and
invokes the same fly-to-player transition the Tab handler runs.
User-initiated fly toggle (DebugPanel button) Cancel()s pending
entry. Skip in offline mode (no ACDREAM_LIVE) — Holtburg orbit
stays default for testing.
2. MouseLookState + KeyBindings.RetailDefaults() binds MMB Hold to
InputAction.CameraInstantMouseLook. GameWindow subscribes:
- Press: hide cursor, capture position, _mouseLookActive = true.
- Release: restore cursor, deactivate.
- WantCaptureMouse=true while held → suspend (release cursor).
- MouseMove while active: combined drive — chase camera yaw +
character heading move together (retail's signature mouse-look
behavior). Camera Y still pitches camera-only.
3. DebugPanel "Toggle Free-Fly Mode" button via DebugVM.ToggleFlyMode
action delegate — replaces the F-key as the primary discovery
path for free-fly. Gated on DevToolsEnabled.
4. ChatPanel.FocusInput() one-shot + IPanelRenderer.SetKeyboardFocusHere
primitive. GameWindow's ToggleChatEntry (Tab) subscriber calls
_chatPanel.FocusInput() so Tab moves focus to the chat input
field. Replaces the K.1c TODO stub.
5. WantCaptureMouse gating reinforcement on surviving mouse handlers
(no new code; verified intact from K.1b).
21 new tests (8 PlayerModeAutoEntry, 10 MouseLookState, 3 ChatPanel
focus). 1183 total green. 0 warnings, 0 errors.
