fix(physics): TS-23 - plumb real PK/PKLite/Impenetrable mover flags
Campaign P Slice P3 item 3. The wire parse (CreateObject's PublicWeenieDesc._bitfield), the decode (EntityCollisionFlagsExt. FromPwdBitfield), the per-GUID storage (ClientObjectTable. PublicWeenieBitfield), and the exemption logic (CollisionExemption. ShouldSkip) all already existed and were already correct -- every mover-flags call site just fed a GUID-prefix IsPlayer heuristic instead of the real per-entity PK/PKLite/Impenetrable state (retail OBJECTINFO::init 0x0050cf30 state |= 0x80/0x800/0x1000). Port: - EntityCollisionFlagsExt.ToMoverState translates the decoded PWD bit-space into the ObjectInfoState bit-space FindObjCollisions actually reads -- two different numberings that must not be confused. Deliberately does not translate IsPlayer (every call site already derives that correctly from its own GUID heuristic per #184 Slice 2b). - EntityCollisionFlagsExt.ResolveMoverPvpState is the one shared ClientObjectTable-backed lookup (guid -> ObjectInfoState), replacing what would otherwise have been three separate inline copies across GameWindow/LivePresentationComposition/RemoteTeleportController. - Threaded as a new optional moverPvpState parameter through RuntimeRemotePhysicsUpdater.Tick/TickHidden and RuntimeOrdinaryPhysicsUpdater.TryBegin (default None preserves every pre-P3 caller unchanged), and as PlayerMovementController.OwnPvpFlags for the local player's own two resolve call sites. - TS-23 section 12b: PlayerWeenie.JumpStaminaCost's pk parameter now reads the real PlayerKillerStatus(0x86)/LastPkAttackTimestamp(0x91) pair against retail's 20-second recency window (pkStatus in {4, 0x40} && (timestamp + 20.0) >= now), replacing the P1 hardcoded false. RuntimeMovementSkillState/Snapshot and LiveSessionEventRouter.RecomputePvpStatus push both the PWD bitfield and the PlayerKillerStatus pair reactively, riding the SAME ClientObject event triggers RecomputeBurden already uses. - A conformance test caught a genuine precision bug in the first PK-timer clock choice: DateTimeOffset.UtcNow's Unix-epoch seconds (~1.7 billion) loses ~128 seconds of precision in a 32-bit float, silently swallowing the entire 20-second window. Switched to Environment.TickCount64 (small, monotonic magnitude) -- also the more retail-plausible basis, since LastPkAttackTimestamp is itself a wire PropertyFloat and retail's Timer::cur_time is almost certainly a process/session-relative counter for the same precision reason, not an absolute epoch. Non-PK invariant (the acceptance criterion): an entity with no ClientObjectTable row, or a row whose PublicWeenieBitfield is null or 0, resolves to ObjectInfoState.None -- a no-op OR into moverFlags, bit-identical to every pre-P3 caller's hardcoded value. A dedicated test drives two real ClientObjectTable rows through CollisionExemption.ShouldSkip and confirms PK-vs-PK collides while PK-vs-non-PK and non-PK-vs-non-PK both stay exempt (walk through). Register: TS-23 retired (both the collision-flags and PK-timer halves); the stale "M2 combat must land TS-23" phase-gate note removed. dotnet build + dotnet test (Core.Tests 4008/2 skip, Runtime.Tests 425/0, App.Tests 3968/3 skip, complete solution build) all green.

fix(physics): TS-46 - seed the sweep from the Setup's own sphere list
Campaign P Slice P3 item 1. Retail CPhysicsObj::transition (0x00512dc0) seeds the collision sweep from CPartArray::GetSphere (the Setup's own <=2-sphere list, each origin+radius scaled by m_scale) via SPHEREPATH::init_sphere (0x0050c670) -- not from a symmetric two-scalar (radius, height) capsule reconstruction. The human Setup 0x02000001's authored spheres are (0,0,0.475) r=.48 and (0,0,1.350) r=.48; the old reconstruction from (0.48, 1.835) produced (0,0,0.48) + (0,0,1.355), a 5 mm head-center offset the TS-46 register row documented as a residual. Port: - SpherePath.InitPath gains a sphere-list overload (ImmutableArray< FlatCollisionSphere>, scale) sharing a new InitPathCore with the existing (radius, height) overload, which is now the degenerate 2-scalar case of the same code -- byte-for-byte unchanged, so every captured-fixture replay (CellarUpTrajectoryReplayTests, DoorBugTrajectoryReplayTests, CellarLipWedgeTests) keeps passing unmodified. - PhysicsEngine.ResolveWithTransition gains optional sphereList/ sphereScale parameters; empty/default preserves the legacy scalar path for every pre-existing caller. - LiveEntityMotionRuntimeController.GetSetupMoverShape is a new sibling of GetSetupCylinder (left untouched) that resolves the Setup's own sphere list plus Setup-derived step-up/step-down (CPartArray::GetStepUpHeight/GetStepDownHeight, 0x005180d0/0x005180f0, x ObjScale, 0.4 m fallback matching the pre-existing literal). - Threaded through PlayerMovementController (both resolve call sites, new SphereList property set by PlayerModeController.ApplyStepHeights and the Headless world projection), RuntimeRemotePhysicsUpdater (Tick + TickHidden), and RuntimeOrdinaryPhysicsUpdater.TryBegin. Remote/ordinary step heights are now Setup-derived instead of a hardcoded 0.4f literal. Projectile and camera-probe sweeps are untouched (already single-sphere-exact). - PlayerModeController.ApplyStepHeights also now applies the x ObjScale multiply to the player's own step heights (previously only the remote/ordinary paths did), closing an adjacent gap the P3 research flagged. Ts46SphereListConformanceTests proves the sphere-list overload sees the exact dat spheres (not the reconstruction), that the scalar overload is unchanged, and that ResolveWithTransition's sphereList parameter actually drives the sweep (a decoy-scalar control pair using a head-height obstacle sphere). Register: TS-46 retired (both residuals it named are closed); header count corrected to 40 active TS rows. dotnet build + dotnet test (Core.Tests 3991/2 skip, Runtime.Tests 425/0, App.Tests 3968/3 skip, complete solution build) all green.

fix(render): read TransparentPartHook opacity by the real part ordinal, not 0
Some checks failed
Headless portability / portable-headless (ubuntu-latest) (push) Has been cancelled
Headless portability / portable-headless (windows-latest) (push) Has been cancelled
Headless portability / linux-graphical (push) Has been cancelled
Headless portability / linux-vulkan (push) Has been cancelled
The user reported crystal shards hovering in the air above every Bind
Stone on Coldeve (setup 0x020010AC) that do not exist in the retail
client. The DAT truth, extracted with the new tools/SetupInspect probe:
the model authors SEVEN parts - pedestal, spinning column, inner
crystal, and four shard meshes parked in a static ring at Z=3.0 in the
placement frame and every frame of the idle cycle - and frame 0 of that
idle cycle fires four TransparentPartHooks (parts 3-6, start=end=1.0)
each loop. Retail hides the shards through those hooks; the model
simply ships with permanently-hooked-invisible parts.
acdream's hook chain was intact end to end - the static-animating
workset captures the hooks (RetailStaticAnimatingObjectScheduler ->
AnimationHookFrameQueue -> TranslucencyHookSink), and
TranslucencyFadeManager committed translucency 1.0 for parts 3-6 -
but BOTH dispatchers' bare-GfxObj branch read the fade with a
hard-coded part index 0 under a false #188-era assumption ("a bare
GfxObj entity has exactly one part"). Every live server object is a
FLATTENED multi-part entity in exactly that branch: SetupMesh.Flatten
emits one bare-GfxObj MeshRef per Setup.Parts[i], order preserved,
AnimPartChanges replacing in place - so the MeshRef ordinal IS the
retail CPartArray ordinal TransparentPartHook.PartIndex addresses.
The committed invisibility for parts 3-6 was never consulted and the
shards drew forever. Proof the ordinal was trustworthy all along:
click-selection in the same loops already publishes it as the part
identity (Slice 4 picking runs on it in production).
Fix: both the legacy classifier and the packed oracle now pass the
per-part ordinal (partIdx / packedPart.PartIndex) to the translucency
lookup. Single-part objects still read index 0; the #188 door fades
are unchanged; the Setup-expanded branch already indexed correctly.
Any other object hiding authored parts via idle-loop hooks gets its
retail appearance from the same change.
tools/SetupInspect is the new reusable DAT probe that cracked this:
dumps a Setup's parts, parent indices, GfxObj vertex bounds, placement
frames, motion-table default cycle, sampled animation frames, and all
animation hooks.
Closes task #32's code side; the connected visual gate (shards gone at
the Bind Stone, base crystals and spin retained) is the acceptance.
App Release suite 3,968 / 3 skips.

fix(render): keep authored surface translucency on composite textures
Some checks are pending
Headless portability / portable-headless (ubuntu-latest) (push) Waiting to run
Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
The user reported wielded items subtly hiding particle effects, as if a translucent texture were missing. Root cause verified in source: the DAT authors a per-surface Translucency float, and the shared-atlas extraction honors it by baking (1 - Translucency) into the texture alpha (MeshExtractor). But a surface with an appearance override - ObjDesc subpalettes or texture changes, which wielded loot typically carries - routes through the per-instance composite paths instead (WbDrawDispatcher.ResolveTexture -> TextureCache GetOrUploadWithPaletteOverrideBindless / GetOrUploadWithOrigTextureOverrideBindless -> DecodeFromDats), and the textured decode there never saw the authored value: only the Base1Solid branch passed it (SurfaceDecoder.DecodeSolidColor); DecodeRenderSurface has no translucency input at all. Consequence: the part still classified translucent, still sorted in the RetailAlphaQueue, still drew with depth writes off - but with texture alpha = 1 it overwrote everything already composited behind it. Particles behind the part vanished; particles in front survived. The same GfxObj without overrides (atlas path) rendered correctly, which is why the loss was so selective and subtle. Fix: SurfaceDecoder.ApplyAuthoredTranslucency mirrors the atlas bake (in-place alpha scale, caller-owned buffers, Magenta sentinel guarded), and DecodeFromDats applies it behind an opt-in flag set by exactly the two world composite paths. The sky path stays unbaked (its shader applies the authored opacity separately - baking would double-apply, the AP-89 compounding class) and particle sheets stay unbaked (emitter-driven alpha, no authored-translucency consumer). Composite cache keys already include the surface id, so the baked alpha is cache-coherent. This closes an unregistered divergence (no register row existed; the fix restores parity with the shipped atlas mechanism, so none is added). Investigation evidence: equipped children and world objects share the same classification chain (ClassifyPackedBatches/GroupKey), so the gap was override-driven, not attachment-driven - a dropped item with the same ObjDesc was equally affected. Core SurfaceDecoder tests 22/22 (3 new); App Release suite 3,968 / 3 skips. Visual gate: a wielded item with authored-translucent parts must let its particle effects show through.

diag(render): composite-warmup stall probe for the session-3 tunnel hang
The 2026-07-29 Coldeve session 3 stuck the player in the portal tunnel forever: generation 2 (Town Network, 0x00070156) published render but composites/collision never became ready, and the reveal latch correctly held the tunnel. The composite warmup queue in WbDrawDispatcher has exactly two permanent-stall shapes - a GfxObj id that never resolves (silent load failure, e.g. custom-server content absent from the baked pak) or an upload budget that never reopens - and they are indistinguishable from the reveal log alone. ACDREAM_PROBE_REVEAL=1 (NetDiagnostics.ProbeReveal) now emits one [composite-warmup] STALL line per second while warmup blocks a reveal: pending count, queue depth, scan state, upload-budget gate, and the first four pending GfxObj ids. Zero cost when off. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

fix(render): the near plane is col3, not col4 + col3 (#248)
`FrustumPlanes.FromViewProjection` extracted the near plane with the Gribb-Hartmann form written for OpenGL's `[-1,1]` clip-space z range. Every acdream projection comes from `Matrix4x4.CreatePerspectiveFieldOfView` or `CreateOrthographic`, whose range is `[0,1]`. Under `[-1,1]` the near plane is the locus of `clip.z = -clip.w`, which is `col4 + col3`; under `[0,1]` it is `clip.z = 0`, which is `col3` alone. Concretely, the mismatch put the effective near threshold at `-n·f/(2f-n)` — about 0.5 m where the retail chase camera asks for 1.0 m. That error only ever kept geometry the true frustum would have dropped, never the reverse, which is why it produced no visible defect and was filed instead of hot-fixed during Campaign V. It is still wrong, and it is the same mistake that *was* visible in `PortalProjection`, where it culled the cell behind a doorway the camera stood close to. The far plane is `col4 - col3` under both conventions and is untouched. A test pins it anyway, so that a future edit to this function cannot drift it while nobody is looking. The acceptance criterion asked for a unit test pinning the extracted near distance to the camera's near value, and that is what landed: a theory over four near/far pairs asserting the plane is unit-length, faces down -Z, and stands off the eye by exactly `nearDistance`, plus a kept/dropped pair straddling it. The test was checked against the old formula before commit and fails all four cases there — it measures the fix rather than merely accompanying it. The other half of the acceptance criterion — unchanged culling in the offline pixel gate and the connected route — could not be run: #259 has Win32 surface creation failing machine-wide, so no gate that needs a window is available tonight. Recorded as outstanding rather than assumed. Solution build 0 errors; `AcDream.Core.Tests` 3,898 passed / 2 skipped / 3,900. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

docs(render): V11 closeout — register, architecture, code structure, issues
Retires the GL framing from the documents that described a two-backend,
two-UI-stack client, and files what the deletion left behind.
Divergence register:
* AD-46 (anisotropic tap pattern in dense alpha scenery) is REFRAMED rather
than retired. Its substance survives -- distant foliage may read denser
than retail's -- but it was measured GL-vs-Vulkan, and with GL gone it is
a Vulkan-vs-retail question against the D3D oracle it already cited. The
measurement is kept as the evidence that the residual is a driver tap
pattern; the row now records that it is no longer falsifiable by
self-differential, which is a real loss the deletion causes.
* AD-47 and AD-48 are NEW, and the campaign's own risk register scheduled
them here: MSAA sample positions (measured at 8.83% of the frame at 4x,
which is why every strict gate runs MSAA off -- and therefore why a
regression confined to the multisample path would not be caught) and
present pacing (#235 is the live instance).
* AD-17's justification moves from a GL clip-plane citation to Vulkan's
maxClipDistances floor, which is the same 8, so the divergence is
unchanged and only its authority moves.
* AP-92 keeps IUiViewportRenderer.TextureIsBottomUp rather than folding it
flat, because it is what let the origin question be answered by data.
Architecture and code structure: the layer diagram, the frame order, the
residency vocabulary and the reference table all said OpenGL. The UI section
said two stacks. Rule 3's rationale is rewritten around what actually
happened -- ImGui was deleted and not one panel, ViewModel or command had to
change, because none of them had ever imported ImGuiNET. That is the rule
paying for itself, so it is recorded as evidence rather than removed as
obsolete.
Issues: #258 files the dev-panel host as a decision rather than an accident,
and #255 is REOPENED. Its TaskCreationOptions.LongRunning fix asks the
scheduler for a thread but does not promise two callbacks overlap; under nine
concurrent test assemblies it still failed 2 of 5 whole-suite runs. The
earlier evidence tested a narrower pool, not a contended one. The fix it
needs is a rendezvous inside the read stub -- not a weakened assertion.

feat(render): Vulkan campaign V11 step 3 — drop the GL packages and shaders
Commit 2 deleted the GL rendering backend's implementations; this step removes the package references and shader vocabulary they leave behind, so nothing in the App project still spells Silk.NET.OpenGL. Silk.NET.OpenGL and Silk.NET.OpenGL.Extensions.ARB are dropped from AcDream.App.csproj. Chorizite.Core stays — the audit is NOT clean: its Render.Enums (TextureFormat, BufferUsage) and Lib.BoundingBox types are used directly and extensively across the Wb texture/mesh pipeline, independent of the deleted GL IUniformBuffer implementers the package comment used to cite. The stale comment is corrected in place. IMeshPipelineDevice.Gl is removed along with the GL? gl parameter threaded through WbMeshAdapter's four constructors, WorldRenderComposition's CreateMeshAdapter, and VulkanMeshPipelineDevice's Gl => null implementation — nothing read any of them once the legacy per-mesh upload bodies were gone (confirmed by grep: the sole non-doc-comment hit was a test assertion). While in WbMeshAdapter.Dispose(), found and fixed a real bug along the way: its teardown still pattern-matched the deleted GL GpuFrameFlightController to decide whether to wait for submitted work, which VulkanFrameFlightController replaced at slice V6a without this site being updated — so the wait had been silently dead on every Vulkan run since then. Retargeted to VulkanFrameFlightController, which carries the same WaitForSubmittedWork(). The GL pixel-format vocabulary (Silk.NET.OpenGL.PixelFormat/PixelType) that WorldTextureArray/TextureFormatExtensions/TextureAtlasManager used for upload validation is replaced by AcDream.Content's existing Silk.NET-free UploadPixelFormat/UploadPixelType enums (added at MP1a to keep the bake tool GL-free); two new members (Rgb, Red, Float) extend that enum with their GL ABI constants to cover the full vocabulary WorldTextureArray needs, since MP1a's original set only covered what the extractor itself emits. ObjectMeshManager's App-boundary cast `(Silk.NET.OpenGL.PixelFormat?)batch.UploadPixelFormat` becomes a direct pass-through now that both sides share the type. GpuBindingModel.StorageTextureTable (the GL-only binding=9 emulation of the Vulkan texture table) is deleted and StorageBindingCount drops from 10 to 9; the descriptor-set-layout code that builds from that count (VulkanPipelineLayouts, VulkanFrameBindings) is untouched and just allocates one fewer always-dummy-seeded, always-unused binding. Several fully dead GL-only classes came along for the ride, confirmed by zero construction sites: SilkFramebufferViewportTarget (NullFramebufferViewportTarget is the sole production IFramebufferViewportTarget), SilkRenderGlStateReader (NullRenderGlStateReader.Instance is the sole IRenderGlStateReader), RuntimeRenderFrameClearPhase (VulkanRenderFrameClearPhase is the sole IRenderFrameClearPhase, expressing the same atmosphere-clear logic as a pass load-op instead), and GpuFrameTimer plus FrameProfiler's GL-owning FrameBoundary(GL) overload and BeginGpuFrame/EndGpuFrame bracket (RecordGpuSample is the only GPU-timing path any backend uses now — the ACDREAM_WB_DIAG nested-query exclusion these existed for no longer applies, since WbDrawDispatcher's own diagnostic GPU sampling already moved to the device's Vulkan timer pool). GpuFrameFlightController itself stays (never constructed with a real fence API in production, but its retirement-ledger/serial-ring logic is backend-neutral and still covered by its own unit tests) — only its GL-specific parts (the public GL constructor overload, SilkGpuFenceApi) are deleted, since removing the whole class would mean restructuring the frozen Slice-8 composition shape's GpuFrameFlightController? threading, which is out of this commit's scope. TextureParameters.cs and BufferUsageExtensions.cs (zero callers each) are deleted outright. common.glsl is deleted: nothing in the actual Vulkan .spv build reads it. tools/ShaderCompiler/Program.cs compiles each .vert/.frag pair directly and tools/ShaderCompiler/VulkanGlslPreamble.cs injects its own complete self-contained preamble per file; common.glsl's textual concatenation was exclusively Shader.cs's GL-only mechanism, deleted at Commit 2. The five shader files that named it in comments (mesh_modern.vert, particle.vert, particle.frag, sky.frag, terrain_modern.frag) are corrected to point at VulkanGlslPreamble.cs instead. mesh.vert/mesh.frag — the pre-N.5 legacy shader pair the mandatory modern path already made unreachable, with zero C# consumers and no compiled .spv — are deleted too. Regenerated via tools/compile-shaders.ps1: 9/9 remaining shader pairs compile (previously 9/10, with mesh the sole failure — the VulkanShaderManifestTests doc comment's "nine of ten are not Vulkan-expressible" was already stale before this commit). Test fallout: dead-subject test methods/files are deleted rather than patched (TextRendererFailureSafetyTests.cs, ClipFrameUploadTests.cs, GpuResourceRetirementTransactionTests.cs's GL queue tests, one WorldRenderDiagnosticsTests source-order test, one RenderFrameResourceControllerTests clear-phase-order test); tests whose subject moved or was renamed are updated in place rather than deleted (GpuContractTests, VulkanCapabilityGateTests, MeshPipelineDeviceSeamTests' pinned seven-member surface now reads six, ParticleBindlessInstanceTests' cross-dialect check now covers the one surviving dialect, WbMeshAdapterTests' misleadingly-named null-gl test — gpuDevice was always the parameter that actually threw). Build: `dotnet build AcDream.slnx -c Release` — 0 warnings, 0 errors, with the Silk.NET.OpenGL/.Extensions.ARB package references physically removed from the csproj (not just unreferenced in code). Tests: full-solution `dotnet test` green across every project. Zero remaining `using Silk.NET.OpenGL` anywhere in src/ or tests/. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

feat(render): Vulkan campaign V11 step 2 — delete the OpenGL backend
Vulkan is the sole, user-signed-off backend (V10 landed) and step 1 already removed ImGui/Studio/DevTools. This step deletes the GL rendering backend itself: every Gpu/Gl/** implementation, the Wb ManagedGL*/GLHelpers/GLSLShader/GLStateScope/RenderStateCache/ BindlessSupport family, Shader/ShaderProgramConstruction/SamplerCache, RenderBootstrap, and RenderFrameGlStateController. GameWindow.cs's Run()/CreateGraphics()/CreateBackbufferReader()/ OnLoad() collapse to their Vulkan-only arm; GameWindowGraphics loses its OpenGlGameWindowGraphics subclass. RuntimeOptions.RenderBackend and RenderBackendKind (incl. the Gl member of GpuBackendKind) are gone — there is nothing left to select between. The five world-draw dual-arm renderers (WbDrawDispatcher, EnvCellRenderer, TerrainModernRenderer, ParticleRenderer, SkyRenderer) and the composition roots (WorldRenderComposition, HostInputCameraComposition, LivePresentationComposition, FrameRootComposition) collapse to their RHI-only arm. GL-only diagnostic properties with a live external reader (DynamicBufferCount and friends) simplify to a documented `=> 0`/no-op rather than disappearing, since the reader is out of this commit's scope. A few GL-flavored mechanisms turned out to be backend-neutral once isolated: GlConstructionCleanupLedger is renamed ResourceConstructionCleanupLedger (exception-chain walking has nothing to do with GL), and GlfwNativePlatformProbe moved out of the otherwise GL-only GraphicalCapabilityRecord.cs into GraphicalWindowBackendSelection.cs before the rest of that file was deleted. Test files with no surviving subject are deleted outright (GraphicalCapabilityRequirementsTests, ShaderProgramConstructionTests, PortalDepthShaderParityTests, TextureCacheBindlessTests, TextRendererFailureSafetyTests, ClipFrameUploadTests, every Gpu/Gl/*Tests, GlTextureOwnershipTests, RenderFrameGlStateControllerTests); others get their dead GL-only members trimmed while their live assertions stay (ClipFrameLayoutTests' MeshClipSsboBinding check now reads GpuBindingModel.StorageClipRegions, the same binding index under its new backend-neutral name; GpuResourceRetirementTransactionTests drops its OpenGLGraphicsDevice-subclassing test double and the two GL queue tests it existed for). EnvCellRendererTests' construction helper now builds a real ObjectMeshManager via VulkanMeshPipelineDevice instead of passing null through a null-forgiving operator, since the RHI constructor never tolerated a null mesh manager and the old GL constructor (which did) is gone. Deferred to the next two steps, deliberately not touched here: the Silk.NET.OpenGL/.Extensions.ARB package references, IMeshPipelineDevice.Gl (WbMeshAdapter's GL? threading stays in place), Chorizite.Core's stale csproj comment (the package itself is still load-bearing — TextureFormat and friends are used well beyond the deleted ManagedGLUniformBuffer), and the CI/gate scripts. Build: `dotnet build AcDream.slnx -c Release` — 0 warnings, 0 errors. Tests: full-solution `dotnet test` green across every project (App.Tests 3937/3940 + 3 skips, Core.Tests 3296/3298 + 2 skips, all others 100%); the 2 App.Tests names that flake under full-suite parallel execution (#250-family, documented pre-existing) pass in isolation.

feat(render): Campaign V slice V11 commit 1 - delete ImGui, Studio, and the DevTools frontend
The ImGui developer-tools stack (AcDream.UI.ImGui), UI Studio (src/AcDream.App/Studio), and the DevToolsFramePresenter/ SettingsDevToolsCompositionPhase ImGui composition machinery are removed. Vulkan never composed a DevTools frontend (DevToolsEnabled already forced false whenever the backend was Vulkan); this commit makes that permanent by deleting the only implementation rather than leaving a dead branch behind. What moved: Studio/SampleData.cs is a live production dependency (InteractionRetainedUiComposition's character-sheet fallback, plus three UI.Layout test files) - git mv'd to src/AcDream.App/UI/Layout/SampleData.cs, namespace AcDream.App.UI.Layout, and trimmed to the SampleCharacter API that is actually still called (BuildObjectTable/AddItem/AddEquipped/the item-guid and icon constants had zero callers left once the Studio fixture provider that used them was deleted). What survives as backend-neutral seams, per the tests that still exercise them: IDevToolsFrameLifecycle (moved into RenderFramePreparationController.cs, now always bound to null), IFramebufferDevToolsTarget/FramebufferDevToolsBinding in FramebufferResizeController.cs (its concrete DevToolsFramebufferTarget adapter is deleted), and IDevToolsGameplayCommands in GameplayInputCommandController.cs (DevToolsGameplayCommands becomes a documented no-op instead of forwarding to the deleted presenter). A follow-up re-homes Settings/Debug onto the retained UI through IPanelRenderer; until then keybind remapping falls back to editing keybinds.json. DevToolsEnabled is now `private const bool DevToolsEnabled = false`. RuntimeOptions.DevTools is unchanged and still reaches VulkanGraphicsContext for the optional debug-utils extensions; Program.cs now logs one line when ACDREAM_DEVTOOLS=1 explaining that the ImGui UI is gone and the flag is Vulkan-only now. Removed: AcDream.UI.ImGui (project + ImGui.NET/Silk.NET.OpenGL.Extensions.ImGui package refs), src/AcDream.App/Studio (minus SampleData.cs), DevToolsFramePresenter.cs and everything only it constructed (ISettingsDevToolsCompositionFactory, RetailSettingsDevToolsCompositionFactory, DevToolsCompositionOwner, IGameWindowSettingsDevToolsPublication, SettingsDevToolsOptionalDependencies, the "developer tools" shutdown-ledger stage and its DevTools-typed fields on IngressShutdownRoots/ RenderShutdownRoots), the ui-studio Program.cs verb, and the cimgui native manifest entries in GraphicalHostPlatformServices. GameWindow.cs's DevTools composition branch, its _vitalsVm/_debugVm/_devToolsComposition/ _devToolsFramePresenter/_devToolsCommandBus fields, and every settingsDevTools .DevTools?.* access across FrameRootComposition.cs/SessionPlayerComposition.cs are gone with it. Build green; complete Release solution suite 8,830 / 5 skips (App Tests 4,097/3 skips run standalone - one #250-family zero-allocation test flakes under the full parallel `dotnet test AcDream.slnx` run, a pre-existing, documented class unrelated to this change).

perf(render): Campaign V slice V8 commit 1 - the Vulkan arm gets an instrument
V8 is the performance gate, and it opened on a plain fact: the Vulkan arm
emitted no [frame-prof] line at all. V6h wired it to
NullRenderFrameGpuMeasurement, whose BeginFrame does nothing - and that method
is the ONLY caller of FrameProfiler.FrameBoundary. So a Vulkan run produced no
CPU frame distribution, no allocation-per-frame column, no frame-history CSV
and no GPU sample. The campaign's own performance vehicle,
tools/run-connected-r6-soak.ps1, waits on [frame-prof] boundaries to time its
samples, so it could not be pointed at the backend V8 exists to judge. You
cannot measure what you have not instrumented, so the instrument lands first.
The bracket is deliberately identical on both arms. On GL,
FrameProfilerGpuMeasurement begins a TimeElapsed query at BeginFrame and ends
it at EndFrame, spanning resource preparation, the world scene and private
presentation, and NOT the swapchain present. VulkanFrameGpuMeasurement opens
and closes a Vulkan timestamp scope at exactly those two points. Two
differently-bracketed numbers in one comparison table would have been worse
than reporting none.
Vulkan timestamps resolve two or three frames late, so the sample carries the
profiler frame index that ISSUED it rather than being credited to the frame
that happened to read it - the pairing GpuFrameTimer already performs
internally on GL. VulkanGpuDevice opens the whole-frame scope tagged with that
index, reads the previous use of the slot back in BeginFrameResources BEFORE
the tag is overwritten, and hands completed (tag, microseconds) pairs to the
adapter through a bounded queue that never blocks.
VulkanGpuTimerPool gains TryTakeResolved, which consumes the value it reports.
TryResolve deliberately reports the last known measurement forever, which is
right for a diagnostic readout and wrong for a percentile: counting one
measurement into the distribution twice is how an instrument flatters itself.
FrameProfiler gains a GL-free FrameBoundary() overload and RecordGpuSample.
Every other line of its bookkeeping - the CPU delta, the per-thread allocation
delta, the stage buffers, the history row, the five-second report - is the same
code the GL arm runs. The GL path is byte-for-byte unchanged in behaviour:
FrameBoundary(GL) still owns and creates the query ring.
Gates: Release build green. App tests 4,152 passed / 3 skipped, exactly the
pre-slice baseline. Strict GL offline pixel gate against

ci(render): Campaign V slice V9 - the Vulkan gate runs on lavapipe
The first CI job in this project's history that renders a frame.
The whole row rests on a decision V6g already made and paid for. When
section 5.5.8 cut set 0 from ten dynamic storage descriptors to four, four
was not merely under the RX 9070 XT's eight - it is Vulkan's guaranteed
minimum, so no conformant device can fail the layout. That is what makes a
software-device row possible at all. Every other requirement was then
checked against Mesa's lvp_device.c rather than assumed, and all seventeen
features the gate demands are true on lavapipe - including
samplerAnisotropy, which V7 made load-bearing eight commits ago and which a
software rasterizer would have been entirely within its rights to decline.
Three things had to exist before the job could:
1. The harness could not stop. VulkanBringUpHost presents until its window
closes, which is right at a desk and impossible in CI, where nothing ever
closes a window. ACDREAM_VULKAN_PROBE_FRAMES gives it a budget; unset or
malformed is zero, which keeps the interactive behaviour, so no existing
invocation changes. The budget never cuts the capture short - the loop
stays open until the screenshot has been attempted - because a run whose
entire product is a PNG must not be able to exit green with an empty
artifact directory. The decision is a pure static method, tested without
a window or a driver.
2. tools/compile-shaders.ps1 was Windows-only and nobody had noticed,
because nothing had ever run it anywhere else. It built its paths from
embedded 'src\AcDream.App\...' literals; a backslash is a separator on
Windows and an ordinary filename character everywhere else, so on Linux
that is one long nonexistent file name.
3. The report's jq paths were invisible to the compiler. Renaming a record
property or swapping the enum converter would have left every test green
and turned CI red on someone else's branch days later, with a failure
that reads like a driver problem. VulkanCapabilityReportContractTests
pins the exact strings the job greps and pins its packed-version
arithmetic against VulkanApiVersion's own unpacking.
The job, eleven steps: install lavapipe and Xvfb; record vulkaninfo as
evidence; publish linux-x64; run the Gpu.Vk tests on a second operating
system; probe the gate under a 24-bit Xvfb screen (the default is 8-bit,
which leaves the X11 WSI without a usable visual) and assert an accepting
verdict on a Cpu device at API >= 1.3 with a clean active probe; assert the
captured PNG is a real frame by IHDR dimensions and byte count; re-run with
ACDREAM_VULKAN_FORCE_UNSUPPORTED=timelineSemaphore and assert exit 4 with an
actionable refusal; recompile the shaders and compare. Artifacts upload on
always(), so a red run ships its own diagnosis.
The .spv step is what ties the committed binaries to their sources. The
existing App test hashes GLSL against the manifest, which catches "edited a
shader, forgot to recompile"; nothing caught a stale or hand-edited .spv.
Verified on Windows before shipping: 19/19 artifacts byte-identical to a
fresh compile, zero drift.
No GL-versus-Vulkan pixel compare, for two independent reasons recorded in
section 5.5.20: linux-graphical asserts exit 4, so there is no left-hand
side, and the probe renders synthetic scenes rather than the DAT world CI
cannot have. The two jobs now say something sharper than a pixel diff would
have - on the same software Mesa stack, GL is refused and Vulkan is accepted
and draws. Physical Linux GPU and Wayland rows stay deferred on the Slice L
precedent; no hosted runner offers either.
Gates: Release build green, zero errors. App tests 4,152 / 3 skipped against
a 4,134 / 3 baseline at this branch's base (

fix(diag): Campaign V slice V7 commit 2 - pin the world clock, because the route never did
THE ROUTE'S TIME PIN NEVER HELD, AND EVERY V7 NUMBER SO FAR WAS TAKEN THROUGH IT.
connected-backend-differential.route.txt opened by pressing
AcdreamCycleTimeOfDay three times, on the stated theory that the cycle walks
live -> 0.00 -> 0.25 -> 0.50 and lands on noon. The mechanism underneath is
WorldTimeService.SetDebugTime, and SyncFromServer clears it -- deliberately,
because that setter is the /time slash command and the command is meant to be a
look-at-dusk-for-a-moment affordance rather than a mode. There is even a test
pinning that behaviour: WorldTimeDebugTests.SyncFromServer_ClearsDebugOverride.
ACE sends TimeSync every few seconds. The clock was therefore un-pinned again
long before the route reached its first stop, on every run this campaign has
taken, including V6m's smoke pair.
The Dereth clock does not only move the sky. It moves the SUN, so it moves the
directional term of every lit surface in the scene.
MEASURED, rather than argued. A probe route captured each stop TWICE, 45 seconds
apart, in the same run on the same backend:
GL, Holtburg, capture 1 vs capture 2: 205,772 px 22.33%
Vulkan, Holtburg, capture 1 vs capture 2: 218,732 px 23.73%
GL, Facility Hub, capture 1 vs capture 2: 108,795 px 11.81%
Vulkan, Facility Hub, capture 1 vs capture 2: 130,206 px 14.13%
One backend, one stop, nothing moving, and a fifth of the frame changes while
you watch. No cross-backend number means anything against that noise floor, and
the cross-backend numbers taken during that probe run were duly absurd -- 56% at
Holtburg, where the two launches happened to be at different times of Dereth day.
THE FIX IS A PIN THAT OUTRANKS THE SERVER CLOCK AND SURVIVES SYNC.
WorldTimeService.PinnedDayFraction is a nullable day fraction that wins over both
Calendar.DayFraction(NowTicks) and SetDebugTime, and that SyncFromServer does not
touch. ACDREAM_WORLD_TIME -> RuntimeOptions.PinnedWorldDayFraction ->
WorldEnvironmentController, which writes it once: the Runtime environment owner
and its clock are session-scoped, so one write outlives every teleport and every
reveal generation. Values outside [0, 1) are REJECTED rather than clamped -- a
day fraction of 12.5 is a typo, and silently pinning the world at it would be
worse than ignoring it.
Unset is the default and every ordinary run. The calendar DATE still advances,
which is intentional: the date drives day-group selection, and ACDREAM_DAY_GROUP
already pins that. The differential gate forces the pin at 0.5 -- noon, which is
what the three presses were aiming at -- on both launches, and the route's
presses are deleted rather than left in as decoration.
This is instrument determinism on the footing of ACDREAM_DAY_GROUP and V7's
ACDREAM_SKY_PHASE_SECONDS, not a workaround: it is off by default, nothing in the
shipping client reads it, and the alternative was to keep measuring two backends
through a fifth of a frame of sunlight.
WHAT IT MOVED. The same three-stop route, same commit otherwise, before and after:
holtburg_town 9.05% -> 2.86% (83,438 -> 26,330 px)
facility_hub_interior 12.16% -> 0.78% (112,075 -> 7,176 px)
aerlinthe_island 23.09% -> 6.82% (212,824 -> 62,892 px)
The interior stop is the headline. V6m recorded it as a route defect on the
theory that the indoor spring-arm camera settles to different distances in two
runs; that theory is now refuted. The camera was fine. The interior was lit
differently because the sun had moved, and with the sun held still the stop drops
by a factor of 15 to 0.78% -- close enough to the 0.001 threshold that its
remaining population is worth naming rather than guessing at. No route change was
needed and none was made.
WHAT REMAINS, per the difference maps, all of it now attributable by eye:
the animated portal beside the Holtburg stop; distant scenery foliage; wandering
NPCs and a chimney smoke plume, which are animation and emitter phase; the vitals
readouts, whose stamina and mana genuinely regenerate at different rates across
two logins minutes apart; and, at Aerlinthe, a dense low-magnitude speckle in a
scene whose mean luminance is 28/255 -- half of its differing pixels are exactly
delta 3, one step over a tolerance that is absolute rather than relative.
Gates. Release build green. App tests 4,134 passed / 3 skipped (one new: the
day-fraction range check); AcDream.Core.Tests WorldTimeDebugTests 6/6, including
the two new ones that assert the pin survives a sync and outranks the transient
override. GL offline pixel gate against the pre-slice tree: 2.66e-05, 15 pixels
of 563,200, inside the documented 9-31 band -- GL did not move.

fix(render): Campaign V slice V7 commit 1 - world anisotropy, and the sky's second clock
Two changes, one measurement. The V6m smoke pair put GL versus Vulkan at Holtburg at 18.52% of the frame differing at tolerance 2 with MSAA off. The same stop on the same instrument now measures 9.05%, and the two populations these address are gone from the difference map rather than merely smaller. 1. THE WORLD ATLASES WERE SAMPLED WITHOUT ANISOTROPY ON VULKAN, AND WITH THE DEVICE MAXIMUM ON GL. RhiWorldTextureArray -- the backend-neutral shared object/material atlas, and the only IWorldTextureArray the Vulkan arm ever constructs -- registered its clamp and repeat slots with GpuSamplerDescription.WorldClamp/WorldRepeat as written, which carry MaxAnisotropy 1. The GL arm asks for the driver's own GL_MAX_TEXTURE_MAX_ANISOTROPY twice over: ManagedGLTextureArray sets GL_TEXTURE_MAX_ANISOTROPY on the image, and the two sampler objects its resident bindless handles are built from (OpenGLGraphicsDevice.WrapSampler/ClampSampler) set it again, which is the one that actually wins. V6i-2 knew it was asking for 1 and said so in a comment -- "the world arm that draws through these arrays is the next slice, and it is the one that can gate a filtering change visually." That slice was V6j, the gate is V7, and this is it. Retail settles the question rather than the GL arm settling it. RenderDeviceD3D::SetDefaultD3DStates (0x005a3800) loops all sixteen sampler stages and issues SetSamplerState(stage, 0xA, this->m_D3DCaps.MaxAnisotropy) at 0x005a4230. 0xA is D3DSAMP_MAXANISOTROPY and the argument is the device's reported cap, not a setting -- so "as much anisotropy as this device has" is retail's own rule, the GL arm is faithful to it, and asking for 1 diverged from retail as well as from the shipping backend. No divergence-register row is owed in either direction: this retires a Vulkan-only gap and lands on retail's value. The fix asks for a ceiling rather than reading a limit back, because the pinned RHI contract (plan section 3.3) carries no anisotropy field and is frozen. It does not need one: VulkanGpuSampler already clamps MaxAnisotropy to VkPhysicalDeviceLimits.maxSamplerAnisotropy, Vulkan guarantees that limit is at least 16 wherever the samplerAnisotropy feature is supported -- which this backend requires -- and 16 is where every desktop driver caps. The request and the GL arm's read therefore land on the same number. What it was worth, from the difference map at the same stop: the roof shingles of both Holtburg cottages, which had been dense hatching across the whole surface, and the stone courses of the near building are now black. Measured as high-frequency energy (mean absolute neighbour difference, GL versus Vulkan) the right-hand roof went from visibly blurred to a ratio of 0.999 and the wall to 1.023; every other textured region in the frame is between 0.99 and 1.02. Grazing-angle surfaces are where anisotropy is the whole difference, which is why a roof was the loudest thing in the frame. 2. THE SKY HAS TWO CLOCKS AND ONLY ONE OF THEM WAS PINNABLE. ACDREAM_DAY_GROUP and the route's AcdreamCycleTimeOfDay presses pin the Dereth date, which chooses the day group, the keyframe and the sun angle. The cloud sheet does not read that clock: SkyRenderer accumulates TexVelocityX/Y against DateTime.UtcNow minus its own construction time, by design, because retail's clouds drift with real time regardless of the date. Two launches minutes apart therefore cannot agree about where the clouds are no matter what the route does, and the V6m smoke measured the cost -- 89% of its 18.52% sat in the top 240 rows. ACDREAM_SKY_PHASE_SECONDS (RuntimeOptions.SkyAnimationPhaseSeconds -> SkyRenderer.AnimationPhaseSecondsOverride) replaces that elapsed-seconds value with a fixed one. Unset -- the default, and every ordinary run -- keeps the wall clock, so nothing a user or the offline gate sees changes. The differential gate forces it on both launches alongside MSAA and the day group; the offline gate keeps its top-280 mask, because a same-commit GL pair still has the sun to disagree about. This is instrument determinism on the same footing as ACDREAM_DAY_GROUP, not a workaround: it is one input to a UV offset, it is off by default, and no shipping path reads it. The alternative on the table was -MaskTopPixels, which would have permanently blinded the campaign's strictest instrument to the entire sky -- one of the five surfaces the offline gate already cannot see. Rows 0-32 of the Holtburg pair went from 23,090 differing pixels to 1,211, and what remains up there is roof and portal rather than cloud. WHAT THE SAME PAIR STILL SHOWS, unattributed and carried to the next commit: the distant treeline, the player and the NPCs, and the animated portal. The portal is phase and expected. The treeline is not filtering -- sharpness now matches within 5% and a shift search finds no sub-pixel offset -- and the two runs entered the world at different last-logout positions (0xC95B0001 versus 0x09040008), so the far-tier streaming history differed. That is the next thing to prove or refute. Gates. Release build green. App tests 4,133 passed / 3 skipped against the 4,132/3 baseline (one new: the sky-phase parse). GL offline pixel gate against the pre-change tree: 2.31e-05, 13 pixels of 563,200, inside the documented 9-31 band -- GL did not move. One offline Vulkan run with VK_LAYER_KHRONOS_validation proven inserted by the loader: zero validation errors, zero warnings. Full three-stop differential recorded at artifacts/v7-diff-c1.

feat(render): Campaign V slice V6m commit 1 - portal space draws on Vulkan
PortalTunnelPresentation was the last raw-GL world-adjacent renderer. It now
draws on both arms, and the composition that used to hand the Vulkan arm a
portal-less teleport presentation is gone with it.
Nothing about the scene changed. Same synthetic DAT Setup resolved through the
same client-enum mapping, same 40 fps CSequence, same retail rotation cadence,
same distant light, drawn through the same already-dual-arm WbDrawDispatcher.
What forked is only where the draw is recorded:
* GL keeps its GLStateScope, its viewport/scissor/depth/cull/blend statements
and its depth-only glClear, untouched.
* The RHI arm opens a backbuffer pass of its own and publishes it on
IWorldPassScope for the span of the draw - the shape V6l gave the two
offscreen viewports, and required for the same reason: the dispatcher's RHI
arm borrows its pass rather than opening one. Publication comes after
BeginPass and before UploadRetailLight, because publishing resets the
frame-global sections and this scene wants its own light, not the world's.
The one substantive decision is the pass's COLOUR load op, and it is a Clear
rather than a Load. Retail preserves the colour target and only clears depth
(UIViewportObject::DrawContent @ 0x006950A5 -> Clear(4) = D3DCLEAR_ZBUFFER), and
so does the GL arm. A Vulkan pass cannot inherit an image the way a bound
framebuffer can: under MSAA the frame's world pass RESOLVES into the swapchain
image and stores DontCare into the multisampled scratch, so a second
multisampled pass declaring Load would load undefined contents - plan section
5.5.12 item 5, the same hazard that merged the clear into the world pass.
Re-clearing is exact rather than approximate because of an invariant the frame
graph already enforces. RenderFrameFoundation.PortalViewportVisible and this
scene's IsVisible are the same value, read once at the top of the frame, and
WorldSceneRenderer returns without drawing when it is set. So whenever portal
space draws, the backbuffer holds exactly the opaque black
SceneTool::BeginScene @ 0x0043DAD0 establishes and nothing else, and clearing to
that same black changes no pixel. The alternative - a single-sampled Load pass
over the resolved image - would have been both a silent MSAA divergence and
invalid, since the backbuffer's depth attachment is multisampled.
The pass takes IWorldPassScope.SampleCount, so WbDrawDispatcher's sample-count
pipeline variants (V6l) select the backbuffer set, and depth matches the
attachment.
CreateRequired becomes internal: its two new seams are internal RHI contracts
and composition is its only caller. The TYPE keeps its visibility - plan section
7.1 rule 3.
Gates. Release build green. App tests 4,132 / 3 skips against the 4,129
baseline (three new: the retail black constant, the RHI arm's composition
precondition, and the both-arms composition assertion). Complete Release suite

feat(render): Campaign V slice V6l commit 3 - the offscreen viewports draw on Vulkan
Amendment 3 of three: the paperdoll and creature-appraisal views render on the
Vulkan arm. Plan section 5.5.16 defect 3 named two backend fixes as the
precondition; both are here, and running it found two more the note could not
have known about.
Fix 1: a layered sampled view per render target. An ATTACHMENT view must be
VK_IMAGE_VIEW_TYPE_2D and the global texture table's descriptor array is
sampler2DArray, so the attachment view cannot legally be registered into it -
section 5.5.7 recorded that as invalid usage rather than a mismatch that samples
oddly, and V6k made RegisterTexture refuse it loudly and name this fix.
VulkanGpuTexture now creates a SECOND, layered view over the same image for a
colour render target: one image, one allocation, two ways of looking at it,
legal without any creation flag. SampledView is what the table registers for
every texture, so the question disappears rather than being answered.
Fix 2: sample-count pipeline variants for WbDrawDispatcher. Vulkan requires a
pipeline's rasterizationSamples to equal the pass it draws in, and this
dispatcher draws in two passes with different counts - the multisampled
backbuffer world pass and the single-sampled offscreen target, which the
contract fixes at one sample. Its five pipelines became a MeshPipelineSet with
two instances, selected at bind time from the live pass rather than from the
scope, which is the same shape section 5.5.8 gave the depth-format problem. When
the backbuffer is single-sampled the two sets are one object, so nothing is
built twice and nothing is freed twice. The offscreen target's DEPTH attachment
also had to take the device's own combined depth/stencil format rather than the
contract enum's literal D24_UNORM_S8_UINT: a pipeline bakes one depth/stencil
format under dynamic rendering and the same pipelines draw in both passes, so a
second format would make one of the two undefined.
Fix 3, which running it found: entity APPEARANCE composites were still
bindless-only, so no entity with a palette override could be drawn on the Vulkan
arm at all - the doll being one, and every creature and player besides. The
backend that serves it has existed since V6i-2 and had no production consumer;
it has one now. TextureCache builds the composite cache on both arms, and
EnsureCompositeTexturesAvailable stops asking about bindless. Nothing about the
cache itself changed: the sharing, the bounded unowned LRU, the metered upload
budget and the retirement fence were already backend-neutral.
Fix 4, which the first successful capture found: the doll rendered upside down.
UiViewport has flipped V since V4a because a GL framebuffer's origin is
bottom-left, so its colour texture samples bottom-up. A Vulkan image's origin is
top-left and the backend's negative viewport height stores the rendered image
that way round, so the same flip stands the doll on its head. That is a property
of the backend that made the texture, not of the widget that draws it, so
IUiViewportRenderer answers TextureIsBottomUp and UiViewport asks. The line this
replaces had predicted exactly this failure since it was written.
The seam. WbDrawDispatcher's RHI arm borrows its pass from IWorldPassScope
rather than opening one, so a viewport that opens a pass of its own has to
publish it there for the span of the draw. Publish is on the interface now for
that. It does not nest: the world phase has closed its own pass by the time
private presentation runs, which is where these viewports have always drawn.
Gates. Release build green. App tests 4,129/3 skips; complete Release suite
9,192/5 (one solution-wide run reported a single App failure that did not
reproduce in the App suite alone or in a second solution-wide run - the
documented rerun-singly flake class; the failing test name was not surfaced by
the runner and is not carried forward as a claim). Strict GL offline pixel gate

feat(render): Campaign V slice V6l commit 2 - the portal mask draws on Vulkan
Contract amendment 2 of three, and V4g's remaining half behind it. Plan section
5.5.16 defect 2: PortalDepthMaskRenderer's two-pass punch (#117) is built on
glStencilFunc/glStencilOp/glStencilMask, GpuPipelineDescription carried no
stencil state at all, and nothing else can express it - so the renderer stayed
raw GL, invisible to the Vulkan arm, and V4g's "stencil/depth-mask pipelines"
row could not be written.
The amendment splits the way core Vulkan 1.3 splits. The ENABLE and the
attachment intent are baked: GpuPipelineDescription.StencilTest, false by
default so no pipeline in the tree changed. The per-draw compare, three outcome
ops, reference and both masks are a GpuStencilState that the pipeline carries as
a DEFAULT and IGpuPassEncoder.SetStencil overrides - exactly the split cull
mode, front face and depth write already have, and exactly what
VK_DYNAMIC_STATE_STENCIL_OP/_COMPARE_MASK/_WRITE_MASK/_REFERENCE make dynamic.
The four stencil dynamic states are declared ONLY by a pipeline that tests
stencil: declaring a dynamic state obliges every draw with the pipeline to have
set it, so adding them unconditionally would make every existing pipeline depend
on a call none of them make. GpuStencilOp carries three values because the punch
uses three - Replace marks, Equal gates, Zero self-cleans - and a fourth would
be a facility with no consumer.
The arm. Three pipelines, not one, because depth COMPARE is not dynamic in the
contract and the punch's two passes differ in it: mark tests LEQUAL and writes
no depth, punch tests ALWAYS and writes, seal is ALWAYS + write with no stencil.
All three write no colour, which is what retail's "COLOR-INVISIBLE triangle fan"
means. The fan is expanded to a triangle LIST on the CPU - the contract has no
fan topology and Vulkan's is not portable - which is exact: triangle i is
(v0, v[i+1], v[i+2]), the same triangles in the same order.
portal_depth.{vert,frag} is a new committed shader pair, and this is the ONE
renderer in the campaign whose two arms do not share a source. Its clip planes
have to travel in the TerrainClip uniform block at binding 2, which is already
precisely this shape and already read by terrain_modern.vert and sky.vert - but
on GL that binding is held globally by ClipFrame for terrain, so a portal draw
that rebound it would leave every later terrain draw in the frame reading the
wrong region. The GL arm therefore keeps its inline program.
PortalDepthShaderParityTests is the tripwire: retail's far-Z constant
(0.99999988, from DrawPortalPolyInternal 0x0059bc90), #129's capped mark-bias
expression and the eight-half-plane loop are asserted to appear in both. Both
are deleted at V11. 9/10 shader pairs now compile to SPIR-V.
Two GL-side gaps closed while the state was being extended, both of section 7.1
rule 1's class rather than new work. GlAmbientCapabilityState now saves and
restores the stencil test, function, ops and both masks - the portal punch draws
mid-frame among renderers that are still raw GL and assume the test is off - and
the COLOUR MASK, which had no consumer until a colour-invisible pipeline existed
and whose absence would have blacked out every raw-GL renderer after such a
pass.
PortalTunnelPresentation was re-read and confirmed as V6k left it: it clears
depth and draws into the active viewport, binds no framebuffer of its own, and
needs no port for section 5.4's sake. It remains unported on the Vulkan arm -
the composition uses NullLocalPlayerTeleportPresentation there - which is an
absence on the V7 list, not a defect.
Gates. Release build green. App tests 4,129/3 skips; complete Release suite
9,192/5 (one solution-wide run reported a single App failure that did not
reproduce in two subsequent runs, solution-wide or alone - the documented
rerun-singly flake class). Strict GL offline pixel gate against

feat(render): Campaign V slice V6l commit 1 - particles draw on Vulkan
Contract amendment 1 of three, and V4e's content behind it. Plan section 5.5.16
recorded that both particle pipelines draw with per-instance VERTEX attributes
and that the pinned contract could express instanced DRAWING but not instanced
vertex INPUT: one stride, no divisor, one buffer at VertexInputRate.VERTEX. That
is what stopped V4e. This takes the reviewed option (i) - a second vertex
binding with a per-instance rate.
The amendment. GpuVertexLayout grows a per-binding notion (binding index,
stride, input rate) and GpuVertexAttribute names the binding it is fed from,
defaulting to 0; IGpuPassEncoder.BindVertexBuffer takes a binding index. Every
layout written before this slice keeps its exact meaning through
GpuVertexLayout.Interleaved, which is one vertex-rate binding 0 - and
GpuContractTests asserts that as a requirement rather than trusting it. Both
backends carry the rate natively and at no cost: VK_VERTEX_INPUT_RATE_INSTANCE
on the pipeline, glVertexAttribDivisor recorded once into the pipeline's VAO
where it survives every later attribute rebind.
GpuVertexFormat.UInt1 comes with it, and is necessary to it: particle.vert
declares `layout(location = 6) in uint aTextureIndex` and the amendment's whole
premise is that no shader is edited. Same kind-distinction UByte4UInt was added
for at V4d - GL needs glVertexAttribIPointer, Vulkan needs R32_UINT, and the
float path would reinterpret the value's bits rather than approximate them.
Options (ii) and (iii) were rejected on the record: all ten storage bindings are
spoken for and reusing binding 0 would have the GL particle draw clobber
WbDrawDispatcher's instance array mid-frame (section 5.5.8's hazard in its GL
form); CPU-expanding instances is 5x billboard bandwidth and does not scale to
mesh particles at all.
The arm. ParticleRenderer.Rhi.cs is a SECOND arm per section 5.5.6, not a
replacement - every GL statement in the sibling file is the one it always
issued. Five pipelines replace the imperative glBlendFunc switch (two billboard
blends, three mesh blends) because core Vulkan 1.3 does not make blend dynamic.
The per-flight VAO/VBO pool disappears because every ring allocation inside a
frame is already distinct memory that lives until the frame retires. The
binding-9 table is not bound at all - the device owns the table and the encoder
binds set 2. The pass is BORROWED from IWorldPassScope. Depth tests but does not
write, compare is Less and alpha-to-coverage is off, which is the ambient GL
state particles have always drawn under rather than a choice. Everything above
the submission seam - emitter iteration, retail distance ordering, the
deferred-alpha handoff, billboard axis construction, blend resolution - is the
same CPU code on both arms.
The first Vulkan particle frame threw rather than drew, which is the second
defect of the compiles-clean class this slice found by running:
TextureCache.AcquireParticleTexture is bindless-only, so the standalone particle
texture cache did not exist on a backend without GL. It exists on both arms now.
Everything about it that matters - sharing equivalent surfaces between emitter
owners, the bounded unowned LRU, retirement behind the frame-flight fence - is
already backend-neutral; only how one entry is created and destroyed differs,
which is what IStandaloneBindlessTextureBackend is for. The RHI arm creates the
image through IGpuDevice.CreateTexture with a real sampler and releases the
table slot before the image, which is the GL arm's order and for the same
reason. The composite cache stays GL-only: it serves entity appearance, not
particles.
The durability fix V6k earned. That slice found the sky declaring a 32-byte
stride against a 36-byte AcDream.Core.Terrain.Vertex - the record carries a
TerrainLayer no sky attribute names - and noted that every .Rhi.cs arm restates
a CPU record's footprint from memory while only sky had a test.
RhiVertexLayoutStrideTests is that test for the rest: world mesh, terrain, sky,
retained-UI sprite, debug line, and both particle bindings, each asserted
against the record or the producer's own float count, plus two sweeps over all
seven for attributes that reach past their stride or name an undeclared binding.
Four private layouts became internal to be assertable; nothing else about them
moved.
Gates. Release build green. App tests 4,121/3 skips (4,109 baseline plus three
contract tests and nine layout tests); complete Release suite 9,184/5. Strict GL

feat(render): Campaign V slice V6k commit 2 - the viewports name their own target, and section 5.4 is discharged
V4g's first half, and the V7 blocker section 5.4 named. What moved. PrivateEntityViewportRenderer - the paperdoll and creature-appraisal viewports - stops hand-rolling an FBO, a colour texture and a depth renderbuffer and asks the device for an IGpuRenderTarget. The pass it opens DECLARES that target rather than binding one behind the RHI's back, and the colour attachment is registered into the global texture table through RegisterTexture like any other texture. Render() returns the UiTextureTableHandle the retained UI already speaks instead of a raw GL name. That deletes the V4a pre-approved transitional seam. GlGpuDevice's RegisterExternalColorTexture / TryResolveExternalColorTexture existed so the UI could blit a texture whose owner the RHI knew nothing about; plan section 7.1's final paragraph gave them exactly this slice as their end, and both are gone along with the GlGpuDevice casts in RetailPaperdollFrameView and RetailCreatureAppraisalFrameView. Those two views are now backend-neutral: they decode a handle instead of registering one. Section 5.4, stated precisely, because the answer is not what the section predicts. The divergence it describes - GL's BeginPass refusing to bind framebuffer 0 for a null target - is NOT on the tree and has not been since the V4c revert at |

feat(render): Campaign V slice V6k commit 1 - the sky draws on Vulkan
V4f's content, landed as a SECOND arm per section 5.5.6: GL keeps its raw world
path through to V10 and the RHI world path ships on Vulkan. Every GL statement in
SkyRenderer is the one it always issued; the encoder arm lives in SkyRenderer.Rhi.cs
and runs only when there is no GL context.
What it produces. ACDREAM_RENDER_BACKEND=vulkan renders the sky: the dome
quadrants, the horizon band, the cloud sheet and the fog gradient, in the same
place and the same colours as the GL capture of the same scene (within a few
units on the channels sampled, which is the day-fraction drift between two
launches). Section 5.5.15's first V7 defect - "the sky is flat fog" - is closed.
Three things differ from the GL arm, each because Vulkan bakes what GL sets. The
per-submesh blend function becomes two PIPELINES, additive for sun/moon/stars and
straight alpha for everything else, because core Vulkan 1.3 does not make blend
dynamic. The SkyParams block becomes a ring slice taken per draw rather than one
buffer rewritten per draw, because a descriptor's contents are read at execution
time, not record time. And the pass is borrowed from IWorldPassScope, because the
frame's one backbuffer pass resolves and a second pass could not load what it
left.
The sky is the first Vulkan consumer of set 1 binding 4. Section 5.5.8 recorded
that UniformSkyParams was missing from the uniform set layout and V6i-2 added it;
until now nothing had ever bound it.
The stride bug, which is the fourth of its class this campaign. The first Vulkan
sky frame drew the dome as a field of blue-white noise. The RHI vertex layout
declared a 32-byte stride - position, normal, texcoord, exactly what sky.vert
reads - while AcDream.Core.Terrain.Vertex is 36 bytes: it carries a fourth
member, TerrainLayer, that no sky attribute names and that the GL arm never
described to a glVertexAttribPointer but did count, because it says
sizeof(Vertex). Nothing else in the frame looked wrong, no validation rule was
violated, and the offline pixel gate masks the sky band, so only a side-by-side
capture found it. SkyVertexLayoutTests now asserts the REQUIREMENT - the stride
is the uploaded record's footprint - rather than today's number.
The last interim handle table is gone. V4t retired the private
GlBindlessHandleTable in WbDrawDispatcher, EnvCellRenderer, TerrainModernRenderer
and ParticleRenderer and deliberately left the sky's, because the sky is the one
world path that mints its own resident handles from TextureCache's raw GL texture
names rather than interning someone else's. It now registers those handles
through V4t's RegisterWorldTextureHandle seam instead, which is the same
mechanical change the other four took, and the class and its tests are deleted
because nothing else ever used them.
TextureCache gains RegisterWorldSurface(surfaceId, repeat), the sky's RHI texture
source: the same DecodeFromDats the GL path uses, created through
IGpuDevice.CreateTexture and paired with a real sampler object rather than baked
into a bindless handle. Keyed by (surface, wrap) for the same reason the GL arm
keys its handles that way - a table entry is a combined image sampler, so the
dome sampled CLAMP_TO_EDGE and a scrolling cloud sheet sampled REPEAT are two
entries over one decoded texture.
Gates. Release build green. App tests 4,109 passed / 3 skipped - the 4,112
baseline less the six GlBindlessHandleTable tests that went with the class, plus
three vertex-layout tests. Strict GL offline pixel gate against

feat(render): Campaign V slice V6j commit 2 - Dereth draws on Vulkan
The three world renderers' submission arms, both pass executors, and the
composition that reaches them. This is the unit three predecessors stopped at.
What it produces. ACDREAM_RENDER_BACKEND=vulkan on the offline scene renders
terrain with blended textures and road overlays, the water edge, static world
meshes, procedural scenery, and the complete retained UI - the same frame the GL
pixel gate captures, from the same camera, minus the sky. artifacts/v6j-vk2.
The shape, and why it is not V4c's. Section 5.5.6 chose option (B) after NVIDIA
rendered the V4c binary 10/10 where AMD's GL stack did not: GL keeps its raw
world path through to V10 as a documented fork confined to the submission seam,
and the RHI world path ships on Vulkan. So V4c's and V4d-2's content returns as a
SECOND arm rather than a replacement. The GL arm issues the same GL statements in
the same order against the same objects; the encoder arm lives in three .Rhi.cs
partials and is entered by one branch per submission site.
Three differences from V4c, each because the tree moved under it. There is no
binding-9 texture table - V4t put the slot on the device and Vulkan binds set 2,
so the arm that used to intern bindless handles simply has nothing to do. The
pipelines carry the device's sample count rather than 1, because Vulkan requires
rasterizationSamples to match the pass and alpha-to-coverage is a no-op at one
sample. And no renderer opens a pass.
That last one is structural, not tidiness. Under MSAA the frame's one backbuffer
pass resolves into the swapchain image and stores DONT_CARE into the multisampled
scratch, so a second pass declaring Load would load undefined contents; the
backend also permits one open pass per frame. VulkanWorldScenePhase therefore
opens the pass, publishes the encoder on VulkanWorldPassScope for exactly the
span of the inner WorldSceneRenderer, and every renderer borrows it.
Three sections are frame-global on GL and cannot be on Vulkan: the SceneLighting
UBO, the per-cell clip regions, and the terrain clip block. GL binds each to a
global binding point and every consumer inherits it. Vulkan binds a descriptor
set per draw, and a renderer's own binds are what select the scope those sections
must land in - so their writers PUBLISH into WorldFrameSections and each renderer
binds them inside the pass, after its own binds. SceneLightingUboBinding's
per-flight-slot buffer pool disappears with it: a ring allocation is already
distinct memory that lives until the frame retires, which is the property the
pool existed to provide.
Both pass executors became backend-neutral rather than gaining twins. Everything
they do is delegation to a renderer except four concerns - the clip-frame
publication, the doorway scissor, gl_ClipDistance enablement, and retail's
interior depth clear - so those four move behind IWorldPassSurface and retail's
ordering, which is what these classes are actually for, is written once. The GL
implementation issues the statements the executors used to issue inline.
Clip distances are no-ops on the Vulkan arm, and that is safe rather than a
divergence: Vulkan activates every element the shader declares, and all three
world vertex shaders already write 1.0 into every slot past the active count.
The interior depth clear becomes vkCmdClearAttachments, reached through the scope
so the pinned contract stays frozen and the backend-only verb stays in the
backend. The hook for it was already committed at V6i-3 with a cref to a type
that did not exist yet; it exists now.
The collision-wireframe DebugLineRenderer is composed as null on the Vulkan arm.
DrawAndPublish flushes it INSIDE the world phase and it opens its own pass, which
the one-pass rule forbids. The toggle is DevTools-only and DevTools is not
composed there, so nothing is lost - composing it would throw on the first
wireframe frame rather than silently misdraw.
Two seams widened rather than invented. GameWindowGraphics answers whether the
backend has a world-pass seam, because the three composition phases that need it
already borrow that handle and "does this backend work that way" is what the type
exists to answer. And MeshSourceReady replaces the anyVao != 0 gate with the same
question in backend-neutral form - V6i-3 published HasStores for exactly this -
so the predicate evaluates identically on GL.
What is NOT here, and is expected. Sky and weather are still raw GL (V4f), so the
Vulkan frame's sky is the atmosphere fog clear. Particles (V4e), the paperdoll and
appraisal viewports and the portal depth mask (V4g) likewise. The executors
already accepted all of them as absent.

baseline; complete Release suite 9,175 / 5. Strict GL offline pixel gate against

fix(render): Campaign V slice V6j commit 1 - the Vulkan winding needs no inversion
VulkanViewportMapping has inverted the front face since V6c, on the standard argument that rendering with a negative viewport height mirrors framebuffer space and therefore reverses triangle orientation. The world arm is the first consumer that culls anything, and it falsified the inversion twice over on one frame. Nothing exercised it before now. Every Vulkan consumer through V6i - TextRenderer, DebugLineRenderer and the bring-up scene - declares Cull = GpuCullMode.None, so the mapping had never decided a single fragment. That is why a wrong answer survived four slices and a validation-clean run: an unexercised path. What the world arm measured, on the same offline scene the GL pixel gate captures. Terrain is the one single-sided surface acdream draws - FrontFace(Ccw) plus Cull(Back), matching ACRender::landPolysDraw's per-triangle eye-side predicate - and under the inversion it vanished completely, 190 multi-draw commands issuing against 625 loaded landblocks with nothing on screen. Every closed building shell rendered inside-out in the same frame: the front wall culled and the interior beams visible through the gap, which is what a back-face-front cull looks like on geometry that is only nearly convex. Declaring the GL winding verbatim restores both at once - terrain draws single-sided from above, and the shells close. Two independent surfaces, one change, and the correction is the identity mapping. Recorded here rather than worked around in the renderers, because a renderer that compensates for its backend is exactly the shape this file exists to prevent: the contract says renderers speak GL and the backend translates, and the backend was translating wrongly. The viewport flip itself is untouched and still correct - it is what puts GL-authored geometry the right way up with no shader or matrix change. What goes is the claim that a winding inversion has to travel with it. The scissor's explicit flip is a separate correction with a separate justification and is likewise untouched. The test suite says so now rather than describing the old behaviour: the pass-through is asserted directly, and the exact-inverses test becomes a travels-alone test, so a later change that reintroduces the inversion fails here first and on any single-sided surface second. Gates. Release build green. App tests 4,112 passed / 3 skipped, the unchanged baseline. GL offline pixel gate unaffected by construction - this file has no GL arm - and measured with the world arm in commit 2. No divergence-register row: this corrects a backend translation error rather than introducing a deviation from retail. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

feat(render): Campaign V slice V6i-3 commit 2 — the Vulkan frame gets a world pass, and descriptors bind at draw time
Two structural prerequisites for the world renderers' submission arms. Both are in Gpu/Vk only; the GL backend executes not one changed statement, and the frame this commit produces is bit-identical to the one before it. 1. The clear merges into the world pass (plan §5.5.12 item 5). V6h gave the clear phase a backbuffer pass of its own: clear, resolve, close. Under MSAA that is a trap for whatever comes next. A multisampled backbuffer pass renders into a scratch image and RESOLVES it into the acquired swapchain image, and the scratch's store op is DONT_CARE — so a world pass that followed and declared Load would load undefined contents and lose the clear entirely. The world renderers cannot work around it by each opening their own pass, for the same reason: every pass after the first would load a discarded scratch. So the clear phase now computes the same RenderFrameFoundation from the same world clock and weather owners and publishes only the COLOUR, through VulkanBackbufferClearState; VulkanWorldScenePhase opens the one backbuffer pass and clears as its load op, with Store=Resolve when the backbuffer is multisampled. That makes it the frame's one clear and its one resolve. The retained UI's pass is single-sampled and targets the swapchain image directly, so it composites over the resolved result exactly as it did. The clear stays unconditional because the frame graph makes it so rather than because anything asserts it: RenderFrameOrchestrator runs resource preparation, then the world phase, then private presentation, with no branch between. A frame with no world still opens the pass and leaves a cleared backbuffer — which is precisely the frame captured below, since nothing draws into the pass yet. 2. Descriptor sets bind at DRAW time, not at bind time. V6i-1 derives a descriptor-set scope from the descriptor state itself, which is what closes §5.5.8's one-binding-two-buffers hazard. But the encoder issued vkCmdBindDescriptorSets from inside BindStorageBuffer/BindUniformBuffer, so the arena resolved after EVERY bind. For the retained UI's one or two binds that is free. For a world renderer binding ten buffers it materialises up to ten scopes per draw — nine of them PARTIAL states no draw ever uses, each claiming a real descriptor-set pair out of a fixed-size pool and each paying a full round of vkUpdateDescriptorSets. Recording the state and resolving it once, where the draw needs it, yields exactly one scope per renderer, which is what the arena was designed to produce. It is legal because descriptor-set binding is independent of pipeline binding when the layouts are compatible, and acdream has ONE pipeline layout by design (§4.4) — the same property that lets a bucketed pass change pipeline for free. The pass still opens with all three sets bound, which is V6h's fix for VUID-vkCmdDraw-None-08600 and stays exactly as it was. Gates. Release build green. App tests 4,112 passed / 3 skipped, unchanged from commit 1. Strict GL offline pixel gate against commit 1: 3.73e-05 (21 differing pixels of 563,200), inside the documented 9-31 px control band — expected, since no GL file is touched. One offline Vulkan run with VK_LAYER_KHRONOS_validation proven inserted by the loader: zero validation errors, zero warnings, and no [shutdown] diagnostic on either stream. The captured Vulkan frame is compared against commit 1's rather than merely eyeballed: 0 differing pixels of 921,600, maximum channel delta 0 — bit-identical across the merge, which is the strongest available evidence that moving the clear into the world pass changed nothing about what is drawn. What this does NOT do: draw a world. See the report for the enumerated remainder. No divergence-register row: no retail-facing behaviour changes.

feat(render): Campaign V slice V6i-3 commit 1 — the mesh pipeline's upload bodies cross the seam
V6i-2 cut IMeshPipelineDevice at the measured surface and proved the mesh
pipeline could be CONSTRUCTED without naming a backend. It said plainly what it
did not claim: "the mesh pipeline does not RUN on Vulkan. Its upload bodies are
still raw GL — GlobalMeshBuffer, the VAO/IBO construction, the layer transfers."
This moves them, and gives the interface its second implementation.
GlobalMeshBuffer takes GL?. The two backing stores were already IGpuBuffer
(V4b); what still needed a context was the vertex array and the attribute
pointers, which have no RHI verb because Vulkan bakes vertex input into the
pipeline. So a backend with none builds the stores and nothing else, publishes
0 for VAO/VBO/IBO, and publishes VertexStore/IndexStore — the same buffers,
named the way a pass encoder binds them. HasStores is the backend-neutral form
of the VAO != 0 readiness test the raw-GL draw paths make. Two bodies fork on
the context and nothing else does: InitBuffers skips the vertex array, and
CommitMigration skips the rebind — on the encoder arm the field swap IS the
atomic publication, because the next pass reads whatever the field then holds.
The store deletion likewise splits: GL keeps its immediate DeleteRetired,
because the arena's own flight gate has already proven no submitted frame can
reference the store, while the other arm has no second deferral to skip and
Dispose is its retirement-queued release.
ObjectMeshManager's RequireGl narrowed to the LEGACY per-mesh upload. Its three
call sites were one modern-path constructor argument and two bodies whose every
GL statement sits inside `if (!_useModernRendering)`. The constructor now hands
the arena the nullable context; the two bodies resolve one lazily inside the
legacy branch. That branch is unreachable in every shipping configuration —
missing bindless or draw-parameters throws at startup under the N.5 ship
amendment — so the accessor survives as the guard on dead code rather than as a
blocker, and it is deleted with that code.
VulkanMeshPipelineDevice is the second implementation, and it is four
properties and two no-ops. Two things about it are worth stating rather than
leaving to be inferred. HasBindless and HasOpenGL43 answer TRUE: their names are
GL-shaped because the seam was cut from a GL device, but what they gate is the
MODERN path — one shared arena, table texture indexing, multi-draw indirect —
which Vulkan supplies unconditionally and the capability gate rejects a device
for lacking, so answering false would disable the only path that exists.
HasPendingWork answers false because the GL device's queue exists to defer work
onto the thread holding the context, and Vulkan resource work is recorded into
the frame's command buffer or routed through the retirement queue.
WbMeshAdapter selects between them once, in the one place the mesh pipeline
still names a backend. The GL arm is unchanged, including the queue-drain
guarantee its construction rollback asserts.
So composition builds the mesh pipeline on BOTH arms, and NullWbMeshAdapter is
deleted — it existed for exactly the gap this closes, and the landblock spawn
ledger now registers against the real adapter. Streaming's publication into GPU
state stops being a no-op there: the Vulkan run below builds real render data,
including the [up-null] zero-vertex caching path.

baseline plus the three added here. Strict GL offline pixel gate against

refactor(render): Campaign V slice V6i-2 commit 3 — the mesh pipeline stops naming a backend
Plan §5.5.10 recorded the blocker as a fact about types: "WbMeshAdapter owns an
OpenGLGraphicsDevice, so it is not constructible on Vulkan until slice V4t" —
which is the entire reason NullWbMeshAdapter exists. §5.5.12 item 6 then measured
how wide that dependency really is, and the answer is seven members out of a
760-line class: a GL context, the retirement queue, the shared instance VBO, and
two capability flags.
IMeshPipelineDevice is exactly that surface. OpenGLGraphicsDevice declares it and
every member already existed under a GL-specific name, so the shipping backend
executes not one changed statement — these are aliases, not behaviour.
Two casts moved, and they are what actually blocked construction:
- ObjectMeshManager downcast IGpuDevice to GlGpuDevice in its CONSTRUCTOR, so a
Vulkan-composed pipeline threw before running a statement. V4t put it there
because the class registered bindless handles itself; commit 2 moved that into
the array, leaving the field a pass-through for the raw-GL renderers' handle
table. The cast now lives on that one property and names the backend it was
composed against instead of reporting a failed cast.
- The atlas array factory is selected by IWorldTextureArrayFactory.For, which is
the one place the texture stack branches on a backend.
MeshPipelineDeviceSeamTests proves the decoupling rather than describing it: it
builds ObjectMeshManager against a device whose Gl is null, asserts it constructs,
asserts construction built no GL object, asserts the handle table refuses by name,
and asserts the factory picks the RHI arm. A reflection test pins the seam's
member set so a later slice cannot quietly widen it back out — the whole value
here is that it is narrow.
What this does NOT claim: the mesh pipeline does not RUN on Vulkan. Its upload
bodies are still raw GL — GlobalMeshBuffer, the VAO/IBO construction, the layer
transfers — and they now fail through one RequireGl() accessor that names the
slice that owns porting them, instead of failing at construction. WbMeshAdapter
still creates an OpenGLGraphicsDevice in its GL constructor, because there is no
second implementation to create yet. Those bodies are items 3–5 of §5.5.12's
remainder list, along with RetailPViewPassExecutor and the three world renderers'
submission arms.
§5.5.13 reports the whole of V6i-2 and the slice table gains its V6i row.

feat(render): Campaign V slice V6i-2 commit 2 — world texture creation crosses to IGpuTexture
Plan §5.5.11 recorded what V4t deliberately left behind: it moved the table
ENTRY of every world texture to the device and kept CREATION with the caches,
because "creating world textures through IGpuTexture is real remaining work and
it belongs with the Vulkan world arm, which is the first thing that cannot use a
GL handle at all." §5.5.12 item 1 handed it forward and named the missing piece
exactly — "an ITextureArray implementation over IGpuTexture, not a codec",
because V6b's BlockCompressionCodec and BlockCompressionMipChain already supply
the BC chains. This is that work.
IWorldTextureArray is the seam, and the slot is what crosses it. Before this
commit ObjectMeshManager read BindlessWrapHandle/BindlessClampHandle off the
concrete GL array and interned them into the device table itself. A 64-bit
ARB_bindless_texture handle has no Vulkan spelling, so the array now answers the
question the caller was really asking — ResolveSlot(wrapping) — and each arm gets
there its own way: ManagedGLTextureArray makes the same idempotent interning call
one level down, and RhiWorldTextureArray returns a pair it registered at
construction. ReleaseTextureSlots replaces the snapshot dictionary the manager
kept for the same reason, and still runs only once physical retirement completes.
Which implementation exists is decided ONCE, by the IWorldTextureArrayFactory
composition builds — plan §3.1's no-runtime-fork rule. Everything above the seam
(capacity policy, slot allocation, ref counting, layer retirement, empty-atlas
eviction, and the whole of ObjectMeshManager's atlas policy) is written once and
branches on nothing.
Three things the RHI array does differently, each because the backends genuinely
differ rather than by choice: BC mip chains are CPU-built through
BlockCompressionMipChain, since Vulkan cannot blit into a compressed image, while
RGBA8 uses the device's blit; filtering lives in an immutable sampler rather than
a texture parameter, so both address modes are registered up front exactly as the
GL array holds two resident handles; and RGB8/A8/Rgba32f are refused at creation
with the reason named. A8 is the interesting refusal — the GL array serves it by
swizzling R into A, and a Vulkan swizzle lives in the image VIEW, which the pinned
GpuTextureDescription does not describe. A silent substitution would render wrong
and look like a shader bug.
TerrainAtlas gains the second construction path V6i drafted and reverted. The
decode is factored out and shared, so both arms read the same DATs, in the same
order, with the same resize-to-max policy; only the upload forks.
ICompositeTextureArrayBackend gains its RHI arm, which is four small methods
because that seam was already a seam.
The Vulkan arm is EXERCISED, not merely present. That is the whole reason the
V6i draft was reverted rather than landed — "built then reverted because nothing
exercised it" — and it is the same failure §5.5.12 measured twice in the
descriptor layouts. So the composition host now builds the real terrain atlas
through IGpuDevice.CreateTexture on the arm with no GL context, and creates and
releases one shared array of each format family plus one composite array at
startup. Creation only; nothing draws them. Releasing them in the same statement
covers one thing a retained bundle would not — that both slot pairs come back and
the images route through the retirement queue.

fix(render): Campaign V slice V6i-2 commit 1 — the terrain clip block reaches set 1
Plan §5.5.12 finding 2, measured on the committed SPIR-V rather than inferred:
terrain_modern.vert declared
layout(std140, binding = 2) uniform TerrainClip { ... }
with no ACDREAM_UBO_SET, so under the Vulkan dialect the block landed in set 0
binding 2 — which set 0's layout declares as a STORAGE buffer. Any terrain
pipeline built against the shared pipeline layout was therefore malformed.
Nothing had caught it: GL expands the macro to nothing and keeps its UBO and
SSBO namespaces separate, the shader compiled cleanly for both backends, and no
terrain pipeline has ever been created on Vulkan. sky.vert declares the SAME
block correctly and is the precedent, so this is a one-word omission, not a
numbering question.
spirv-dis on spv/terrain_modern.vert.spv, before and after:
before %372 = OpVariable %_ptr_Uniform__struct_370 Uniform
OpDecorate %372 DescriptorSet 0 / Binding 2
after OpDecorate %372 DescriptorSet 1 / Binding 2
with %_struct_370 = OpTypeStruct %int %_arr_v4float_uint_8 — TerrainClip's
{ int uTerrainClipCount; vec4 uTerrainClipPlanes[8]; } — in both.
The same commit closes §5.5.8's second recorded gap. Set 1's layout declared
only bindings 1 and 3, so it was missing BOTH the terrain clip block and
UniformSkyParams at binding 4, which sky.vert and sky.frag have compiled to
SPIR-V since V6e. Both are now declared, all four dynamic, which is half
Vulkan's guaranteed maxDescriptorSetUniformBuffersDynamic of 8 and is asserted
by the capability gate as before.
Membership and ORDER now come from one predicate — IsDeclaredUniformBinding —
that the layout, the descriptor writes and vkCmdBindDescriptorSets's
dynamic-offset array are all built from, the same shape V6g gave set 0. The
three had been restated separately, which is exactly how a fifth binding would
have gone wrong the same way.
Both gaps were found by hand, months apart, and neither could fail on the
shipping backend. VulkanShaderDescriptorContractTests reads the committed .spv
and asserts the partition instead: every uniform block at a declared set-1
binding, every storage block inside set 0's declared range, every sampled
resource in the one texture table. Checked out against the pre-fix .spv, two of
its four tests fail.

feat(render): Campaign V slice V6i-1 - one descriptor set per renderer scope
Plan section 5.5.8 recorded, and deliberately did not fix, that pointing one
binding at a second buffer within a frame silently corrupts the draws already
recorded against it: the backend rewrote the descriptor in place, and a
descriptor set's contents are read when the command buffer EXECUTES, not when it
was recorded. Nothing fired it while the Vulkan frame held only the retained UI.
Section 5.5.11 handed it forward as the first thing the world arm would hit,
because WbDrawDispatcher, EnvCellRenderer and TerrainModernRenderer each own
their own instance, batch and indirect buffers and all three bind set 0 in one
frame.
It is closed here, as its own commit and BEFORE the world arm, so that a blank or
corrupt first Vulkan world frame cannot be this defect wearing another face. That
sequencing is the point: sections 5.5.1 to 5.5.3 cost this campaign three days
because an instrument that was "usually right" sat underneath the thing being
measured.
What changed. There is no longer one (set 0, set 1) pair per flight slot; there
is an arena of them. VulkanBindingScopeArena - pure bookkeeping, no Vulkan
handles, nine unit tests - answers two questions per bind: which pair, and do its
descriptors need writing. VulkanFrameBindings keeps the Vulkan half: allocating
pairs from a growable pool list and writing the twelve descriptors when told to.
The scope key is the descriptor state itself - the ten storage buffer identities
and ranges, the plain bindings' offsets, and the two uniform buffer identities
and ranges. Deriving it is a decision, not an economy. The pinned contract has
nowhere to name a scope: BindStorageBuffer takes a buffer, an offset and a size,
and section 3.3 is frozen. Deriving also gives two properties a declared scope
would not: a renderer cannot forget to declare one, and two renderers that
genuinely share every buffer correctly share one pair rather than being told to
differ. A renderer's buffers are stable for its lifetime, so "distinct descriptor
state" is exactly "renderer scope".
Dynamic offsets stay free. A ring allocation moving between draws rides
vkCmdBindDescriptorSets's dynamic-offset array, so it costs neither a new pair
nor a descriptor write - section 4.4's "zero descriptor writes per frame"
property survives a frame having more than one binding state in it. Entries are
not invalidated at BeginFrame either, because the slot's previous submission has
retired and its descriptors still say what this frame is about to say; a steady
frame therefore rewrites nothing at all. An entry matched from the previous frame
is swapped below the live cursor so the rest of the frame cannot take it for a
different state - the ordering property the sixth test pins, where two renderers
swap submission order between frames.
What this does NOT do is draw a world. The captured Vulkan frame is still V6h's
retained UI over the fog clear, so the arena's multi-scope path is exercised by
its tests and not yet by a frame. That is recorded in the plan rather than
implied.
The plan's section 5.5.12 also records two blockers measured while scoping the
world arm and not fixed here: terrain_modern.vert declares TerrainClip without
ACDREAM_UBO_SET, so under the Vulkan dialect it lands at set 0 binding 2 where
the layout declares a storage buffer - the same class of gap 5.5.8 recorded for

docs(render): record V4t at the committed tree, and correct one stale comment
Marks V4t done in the slice table with its two commits and per-commit gate numbers, adds §5.5.11, and ticks off step 3 of §5.5.9's corrected sequence. §5.5.11 records four things the world arm needs and one it should not re-derive: why §5.2's "the device's table is unreachable" argument expired rather than being worked around (its premise was that V4c would move the world renderers onto the encoder; §5.5.6 closed that, so the block became indefinite); that V4t landed narrower than §5.3 sized it, keeping texture creation and residency with the caches and moving only the table entry, with `IGpuTexture` creation deferred to the world arm that actually cannot use a GL handle; why `GroupKey`'s ordering survives a retype of one of its fields; and the pixel-gate control measurement, because one capture read 5.50e-05 against a documented 15–23 px band and the honest response to that is a control, not a paragraph. The decisive number is the 9-px difference between captures at the two V4t commits — two different commits, fewer differing pixels than the same-commit control. `GlBindlessHandleTable`'s own doc comment claimed four renderers own instances. Three of them no longer do. It now names its one remaining owner, `SkyRenderer`, says why that one is different (its textures come from the raw GL-name path V4t did not retype), and names V4f as the slice that deletes both the table and the class. `common.glsl`'s binding-9 comment carries the same stale list. It is left alone deliberately: the file is a shader source with compiled `.spv` artifacts and a V9 freshness gate, so a comment-only edit there is not free, and what the comment says about what binding 9 IS remains correct.

feat(render): Campaign V slice V4t-2 — the world texture stack crosses to GpuTextureSlot
The rest of V4t. The composite, particle and shared-atlas texture paths now
hand out the device's GpuTextureSlot instead of a raw 64-bit
ARB_bindless_texture handle, and GroupKey, CachedBatch and ObjectRenderBatch
carry that slot. WbDrawDispatcher, EnvCellRenderer and ParticleRenderer retire
their interim GlBindlessHandleTable instances and share the device's one
table, exactly as V4t-1 did for terrain. Nothing about world submission
changes otherwise: these three renderers are still raw GL, still bind binding
9 themselves, and still draw the same geometry in the same order.
**What produces a slot now.** CompositeTextureArrayCache's GL backend interns
each array's handle when it makes it resident and retires the entry when it
makes it non-resident, so the pair is created and destroyed together and the
cache above it never learns a device exists — the fake backend its tests use
mints a stand-in slot. TextureCache.AcquireParticleTexture does the same for
the one-layer particle arrays it owns, including on its rollback path.
ObjectMeshManager registers each shared atlas's wrap/clamp handles at batch
upload; registration is idempotent by handle, so the many batches sharing an
atlas share its entry.
**Slot release is stricter than what it replaces, not looser.** The interim
tables never released anything — the class comment said so — and they grew
without bound. The device's table has a fixed 16,384-slot capacity, so an
unreleased entry is now a leak with an end. Every producer therefore retires
its entry: the composite backend at MakeNonResident, the particle backend at
MakeNonResident, and ObjectMeshManager when a retiring atlas's PHYSICAL
retirement completes — the point at which its handles are already non-resident
and its texture already deleted. That last one needs the handles snapshotted
at eviction, because ManagedGLTextureArray.Dispose zeroes its own copies as
its first act. Teardown deliberately does not release: the device is being torn
down alongside its callers, so there is nothing left to recycle a slot into,
and deferring work through a possibly-disposed retirement queue would turn a
clean shutdown into a throw.
**The default value became load-bearing, and that is the one real hazard here.**
BindlessTextureLocation could say "not resolved" with handle 0, because no
texture has handle 0. A slot index has no spare value — default(GpuTextureSlot)
is real slot 0 — so a positional record would have turned every
budget-rejected or still-uploading composite into a silent read of whichever
texture registered first. That is the magenta-placeholder failure shape one
layer down. The type is now a struct storing the slot one-based, so default IS
Unresolved, with a test pinning both halves: default is unresolved, and a
location naming slot 0 is resolved and distinguishable from it. Elsewhere the
sentinel is already exact — GpuTextureSlot.Unassigned is 0xFFFFFFFF, which is
common.glsl's ACDREAM_TEXTURE_NONE — so the classify path's "no texture yet"
test and the particle billboard's untextured branch are unchanged in meaning.
**GroupKey ordering is preserved because the key never ordered anything.**
Handle→slot is a bijection (the device interns one slot per resident handle),
so the same (entity, batch) pairs bucket together as before. The key reaches
equality, hashing and the scene-digest fingerprints — never a comparator:
opaque and translucent groups sort by cull mode then camera distance, the
delayed-alpha path by viewer distance then submission ordinal, and group
enumeration follows the persistent dictionary's insertion order, which a
changed hash does not disturb. The digests hash the slot index where they
hashed the handle; both sides of the render-shadow comparison compute them the
same way, so the value changing is invisible to it. Read
CompareOpaqueSubmissionOrder, CompareTransparentSubmissionOrder and
AlphaFingerprintComparer before doubting this — sort-order drift is a
pixel-visible regression class this project has hit, and it is why the check
was made before the retype rather than after.
**One visibility change, forced rather than chosen.** BindlessTextureLocation
was public and now holds an internal contract type, so it is internal;
ObjectRenderBatch.TextureSlot is internal on an otherwise public class for the
same reason. Nothing outside this assembly and its InternalsVisibleTo test
assemblies named either.
**SkyRenderer keeps its interim table**, and the report should say why: the
sky's textures are minted by SkyRenderer itself from TextureCache's raw GL
texture names, which this slice does not retype, so it would be the one
consumer registering handles it produced — a different shape from the world
stack. The offline gate also masks the sky band, so the one automated
instrument here cannot see a sky regression. V4f owns that renderer.

feat(render): Campaign V slice V4t-1 — terrain crosses to GpuTextureSlot
V4t moves the world texture stack off the raw 64-bit ARB_bindless_texture handle and onto GpuTextureSlot. This first commit does terrain only, because terrain is the one branch of that stack whose producer and consumer are a single pair — TerrainAtlas and TerrainModernRenderer — so it can carry the new device seam on its own pixel gate before the mesh/composite/particle retype lands on top of it. Why the device's table can now be reached, when §5.2 said it could not. That paragraph's reason was the flush: GlGpuDevice drains its dirty table runs inside FlushBeforeDraw, which only an encoder-recorded draw reaches, so a raw-GL renderer would sample a stale table. §5.5.6 then closed the GL re-land of V4c/V4d, which means the world renderers stay raw GL through to V10 — so "wait for the encoder" stopped being a plan and became an indefinite block on V4t, which the Vulkan world arm cannot be written without. The resolution is the smallest one that keeps the seam honest: the drain is factored out as GlGpuDevice.FlushTextureTable, and a raw-GL renderer calls it and binds TextureTableGlName at binding 9 itself, immediately before its own draw — the same shape its retired private GlBindlessHandleTable had, against a table that is now the device's. Nothing else of the backend is exposed, and both members are deleted with the raw-GL world path. Residency ownership deliberately does NOT move. RegisterWorldTextureHandle interns an already-resident handle and owns only the table entry; the atlas still creates, makes resident and destroys its own textures. That is what separates it from RegisterTexture, which owns the residency it creates, and it is why this slice can retype the data model without also porting GL texture creation onto IGpuTexture. TerrainAtlas.GetBindlessHandles becomes GetTextureSlots(GlGpuDevice). Registration is idempotent by handle, so the per-draw call is two dictionary lookups — the cadence GetOrAdd already had. It is conditional on the handle having changed because SetAnisotropic makes both textures non-resident and re-acquires them: without that check a quality-preset change would strand a slot holding a non-resident handle, so the superseded entry is retired in the same step through the device's retirement queue. Ordering is unaffected. Terrain's two slots travel as loose uniforms (uTextureIndexA/B) and enter no sort and no bucket key, so a different slot NUMBER changes nothing about what is drawn or in what order — only which table index resolves to the same handle.

feat(render): Campaign V slice V6h — the Vulkan composition host
ACDREAM_RENDER_BACKEND=vulkan now runs the real GameWindow composition rather
than a second main(). All nine phases execute: DAT load, streaming, camera,
entity table, session, and the real retained UiHost drawing through the RHI.
No world renderers — they are raw GL until V4t and the world arm behind it.
The offline log is the client's own (acdream.pak opened, 6266 spells, Region
0x13000000, "loading world view centered on 0xA9B4FFFF", fourteen retail
LayoutDesc lines, streaming radii), and the captured frame is the retail
retained UI: vitals, combat/spell bar with DAT scarab icons, the nine-slot
toolbar, chat with tabs and Send, radar/compass with dat-font glyphs. Sampled
against the GL capture the widgets agree — chat interior RGBA (25,24,27,158)
vs (22,21,23,158), vitals bar (117,1,0) and toolbar slot (0,11,17) identical.
Three seams, as §5.5.9 specified:
1. Platform acquisition — already generic — publishes GameWindowGraphics
instead of a bare GL. Phases that still speak raw GL read Graphics.Gl and
take their Vulkan arm when it is null; each branch names the slice that
removes it.
2. VulkanHostInputCameraCompositionFactory is a new file and the whole of the
Phase-1 fork: four graphics members differ, input/camera/pointer delegate.
The default factory is chosen inside the phase from the platform result.
HostInputCameraResult gained backend-neutral Retirement and FrameSlots.
3. The frame root forks on one condition. The GL world-scene assembly is
unchanged, wrapped in `if (gl is not null)`; the Vulkan arm's graph is one
backbuffer clear pass computing the same RenderFrameFoundation from the same
clock and weather owners, then private presentation over it.
§5.5.9's three TextureCache couplings are unpicked: the constructor takes GL?
and rejects bindless without one, world entry points route through a Gl
property that throws naming V4t, and the (GlGpuTexture) VRAM-accounting cast
became a backend test. That cast's stated reason — DrawSprite's texture-unit
binding — was already stale, deleted at V6d.
VulkanBringUpHost is reduced to the capability-probe harness it is named for:
the instance/surface/device/swapchain sequence moved into VulkanGraphicsContext,
which the composition host and the harness now share. It is reached only with
ACDREAM_VULKAN_PROBE=1.
One latent Vulkan defect surfaced and is fixed here. The first composition-host
frame died with ErrorDeviceLost; validation named VUID-vkCmdDraw-None-08600 —
descriptor set 2 never bound. VulkanGpuPassEncoder bound sets 0/1/2 only as a
side effect of BindStorageBuffer/BindUniformBuffer, so a pass sampling the
texture table while binding no buffer — every retained-UI and debug-line pass —
drew with the table unbound. It survived V6c-V6g because the bring-up host
always drew VulkanRhiScene first and the UI pass inherited its binds; the
composition host has no 3-D scene. The fix is one line in the encoder's
constructor beside the viewport and scissor defaults, which exist for exactly
the same reason: a pass opens with complete binding state rather than depending
on what preceded it.

fix(render): Campaign V slice V6g — the Vulkan frame stops lying to the driver
V6f ran the bring-up host once under VK_LAYER_KHRONOS_validation and found
seven VUIDs, every one of them on the path any world frame takes (plan
§5.5.7). This closes all of them, plus a fourth defect in the same log that
§5.5.7 did not call out. The host now runs validation-clean: zero errors and
zero warnings over 39,855 frames.
Nothing outside Gpu/Vk/ is touched, so the GL backend executes not one changed

feat(render): Campaign V slice V6f-3 - terrain's atlas reads cross the dialect
The last thing keeping terrain_modern out of SPIR-V was how it named its two
atlases:
#define uTerrain sampler2DArray(ACDREAM_TEXTURE_HANDLE(uTextureIndexA))
#define uAlpha sampler2DArray(ACDREAM_TEXTURE_HANDLE(uTextureIndexB))
`sampler2DArray(handle)` is a GL_ARB_bindless_texture construction with no
Vulkan equivalent. Vulkan's table is an opaque descriptor array in set 2; there
is no handle, so there is nothing to construct a sampler from. The ten sample
sites now go through ACDREAM_SAMPLE_ARRAY, the dialect-neutral read V6e
introduced for mesh_modern, wrapped in two shader-local macros that keep the
call sites reading as "sample the terrain atlas" rather than "index the table".
They are SAMPLING macros, not sampler-returning ones, and that is not
cosmetic. Under Vulkan the expansion carries `nonuniformEXT` on the indexing
expression, and binding the result to a local sampler2DArray first is exactly
where an implementation may drop it. The old `#define uTerrain
sampler2DArray(...)` was textually that shape, so preserving it would have
reintroduced the hazard at every use site.
On GL nothing about the sampled result changes: the same slot resolves through
the same binding=9 table to the same handle to the same texel, and the macro
expands to the identical expression the shader wrote by hand.
With this, terrain_modern compiles for Vulkan and the manifest reads 8/9. The
remaining pair is `mesh`, which the campaign doc records as having no consumer
at all - so every production shader acdream actually draws with is now
Vulkan-expressible. That closes the obligation §5 recorded against V6e ("the one
production pair still not Vulkan-expressible after V6e is terrain_modern") and
it closes the shader half of V4d's parked content.
What this does NOT do is give the Vulkan backend a world to draw. That is
reported separately with the rest of slice V6f; the shaders were the part that
could be finished, gated and landed on GL today.

feat(render): Campaign V slice V6f-2 - terrain's tiling table becomes a buffer
terrain_modern.frag declared `uniform float uTexTiling[36]` - the per-layer
tiling factors retail passes to TexMerge::CopyAndTile / TexMerge::Merge, one per
terrain atlas layer. Vulkan GLSL has no default uniform block, so a loose array
is unspellable there, and 144 bytes of payload cannot ride the pinned 96-byte
push-constant block. GpuBindingModel reserved UniformTerrainTiling (binding 3)
for exactly this at slice V4d. The array now lives in that block.
The ELEMENT TYPE is deliberately unchanged. std140 pads every array element out
to 16 bytes, so the block is 576 bytes rather than 144, and packing four values
per vec4 would be tighter - but it would also rewrite the accessor and every use
site, and this commit's whole value is that its pixel gate measures the move to
a uniform buffer and nothing else. `uTexTiling[int(layer)]` reads exactly as it
did.
That padding is the hazard the change introduces, so it is pinned twice. The CPU
writer walks TerrainTextureTilingTable.UniformElementStrideBytes and zero-fills
the dead words rather than blitting 36 packed floats, and a new test asserts the
stride is 16, the block is 576, and the two are consistent with LayerCapacity. A
tightly-packed writer would not crash or even look obviously wrong: the shader
would read layer 0's factor for layers 0-3, layer 4's for 4-7, and in a scene
where most layers tile at 1 the error stays invisible until a layer that does
not appears. Nothing else in the suite could see that.
The buffer is allocated once in the constructor, through the same
TrackedGlResource + ResourceCleanupGroup rollback path every other terrain
buffer uses, written on the first bound draw - preserving the upload-once
property the linked program's uniform had for free - and released through the
dispose ledger. It is REBOUND every draw rather than once: GL's uniform-buffer
binding points are global and shared with SceneLighting at 1 and the sky's
params at 4, so a renderer running between two terrain draws can take binding 3
out from under us. Self-contained render state, per the standing rule.

feat(render): Campaign V slice V6f-1 - converge terrain's view and projection
terrain_modern.vert combined two loose mat4 uniforms per vertex:
gl_Position = uProjection * uView * vec4(terrainPos, 1.0);
Vulkan GLSL cannot express that. There is no default uniform block, so a loose
`uniform mat4` is unspellable however it is written, and the two matrices are
128 bytes against a pinned 96-byte push-constant block (and against Vulkan's
guaranteed 128-byte ceiling). GpuPushConstants already carries exactly one
uViewProjection, which is the shape every other ported shader reads. So the
product moves to the CPU and the shader reads the single matrix.
The transform is identical. System.Numerics uses row-vector convention and
Shader.SetMatrix4 uploads untransposed, so GLSL reads each uploaded matrix as
its transpose. The old expression evaluated Proj^T * View^T; the new one
evaluates (View*Proj)^T, and those are the same matrix. The renderer already had
that product in hand - `viewProjection` at line 422, computed for the visibility
pass - so nothing new is multiplied. It is multiplied once per frame on the CPU
instead of once per vertex on the GPU.
That last sentence is the whole reason this is its own commit. Moving a float
product from GPU to CPU is a real numeric change: different hardware, possibly
different fused-multiply-add behaviour, certainly a different rounding order.
The plan's V4d row requires its pixel effect be attributable alone rather than
folded into a plumbing change, and terrain fills most of the offline gate's
scene, so this is the strongest measurement that gate can make.

feat(render): V6e — the sky's uniforms become a buffer and its texture a table slot
Campaign V slice V6e, last of three. Sky was the hardest of the four pairs
because it was the only one that still worked the way a 2004 shader works: a
dozen loose uniforms pushed one glUniform call at a time, and a texture bound to
unit 0 with a sampler object chosen per submesh. Vulkan GLSL has neither a
default uniform block nor a way to declare a bare sampler, so both had to move —
and the second one had a sting in it.
The uniforms go into a `SkyParams` std140 block at uniform binding 4, the new
pre-authorized constant in GpuBindingModel (1, 2 and 3 are SceneLighting, the
terrain clip block and terrain tiling; the contract test now proves the three
constants and that literal 2 do not collide). Three matrices are 192 bytes on
their own, so the 96-byte push-constant block was never in the running. The
block's member order IS its layout: std140 aligns a vec3 to 16 bytes while using
12, so each of the three lighting vectors is followed by the float that rides in
its pad word, which is why colours and per-surface scalars interleave rather
than grouping by meaning. SkyParamsLayoutTests asserts all twelve offsets and
the 256-byte size, because getting one member wrong would read the sun direction
as a colour with no compile error, no link error and no GL error to say so.
The texture is the interesting half. sky.frag now reads through the shared table
(ACDREAM_SAMPLE_2D), and a bindless handle BAKES its sampler — so the
per-submesh Repeat-versus-ClampToEdge choice, which used to be a glBindSampler
on unit 0, becomes which slot the submesh asks for. SkyRenderer interns one
handle per (texture, wrap) pair, exactly as ManagedGLTextureArray has done since
the world path went bindless, and exactly the shape Vulkan's table has, where an
entry is a combined image sampler. Same two SamplerCache objects, same wrap
behaviour, consulted once at interning instead of once per draw. A pleasant
consequence: the sky no longer touches texture unit 0, so the load-bearing
`BindSampler(0, 0)` restore at the end of the pass — there because the binding
was global state that would otherwise force ClampToEdge on the next renderer —
has nothing left to undo and is gone.

feat(render): V6e — both particle shaders cross the dialect
Campaign V slice V6e, second of three. Billboard particles and mesh particles
are the last two pairs blocked on the texture-table shape; sky follows.
particle takes the same treatment mesh_modern took: the `flat uvec2` handle
varying becomes a `flat uint` slot and the fragment stage samples through
ACDREAM_SAMPLE_ARRAY. What is different here is the untextured particle. The
shader used to ask "is the handle I was given zero", which GL can answer because
its emulated table stores handles; Vulkan cannot, because set 2 is an opaque
descriptor array and reading an element nobody wrote is undefined rather than
zero. So the question moves to the index: the CPU writes ACDREAM_TEXTURE_NONE
for a particle with no texture instead of interning the null handle as a table
slot, and both dialects test the same value. GL renders identically — the same
particles take the same branch to the same procedural blob — and the handle
table simply stops carrying an entry that never named a texture. A test pins the
sentinel across all three declarations of it, because a silent disagreement here
would sample slot 0xFFFFFFFF instead of drawing the blob.
particle_mesh needed no restructuring, only names. Vulkan GLSL has no default
uniform block, so `uniform uint uTextureIndex;` is not unsupported but
unspellable, and the two values are per-pass — one texture and one layer for a
whole sub-batch — which is exactly what the shared push-constant block is for.
uTextureIndex becomes uTextureIndexA; uTextureLayer becomes uParamA, which was
the spare scalar and is a natural fit because the shader converted the layer to
float anyway. The widening moved from the shader to the CPU; layers are small
integers, so the sampled value is bit-identical.

feat(render): V6e — move the world mesh's texture lookup to where Vulkan can express it
Campaign V slice V6e, first of three. mesh_modern is the shader every world
static, every piece of scenery and every EnvCell surface draws through, and it
was one of the four production pairs the SPIR-V toolchain still refused.
The blocker was a varying. Since V2 the vertex stage looked a batch's table slot
up in the binding=9 handle table and forwarded the resulting 64-bit
GL_ARB_bindless_texture handle to the fragment stage as a `flat uvec2`. That
works on GL because a bindless handle is just a number a shader may carry
anywhere. It cannot work on Vulkan at all: the equivalent object is a descriptor
in set 2, and a descriptor is not a value a stage can hand to another stage. So
what travels between the stages is now the SLOT — a `flat uint` — and the
fragment stage does the lookup at the point of sampling.
That relocation needs one shared idea, because the two backends disagree about
what the lookup IS. `ACDREAM_SAMPLE_ARRAY(slot, uvw)` asks the dialect-neutral
question — "sample table slot N" — and expands to
`texture(sampler2DArray(gTextureTable[slot]), uvw)` under GL and to
`texture(uTextures[nonuniformEXT(slot)], uvw)` under Vulkan. It is deliberately
a SAMPLING macro rather than a sampler-returning one: `nonuniformEXT` belongs on
the indexing expression itself, and binding the result to a local
`sampler2DArray` first is exactly where an implementation is free to drop it.
That is the same shape V6d already used for the retained UI's 2-D reads, and it
now covers the array reads the world path needs.
`ACDREAM_TEXTURE_NONE` lands alongside it, unused here and used by the next
commit. GL can ask "does this slot hold a texture" of the payload, because an
unregistered slot holds the null handle; Vulkan cannot, because set 2 is opaque
and reading an unwritten element of a partially-bound array is undefined rather
than zero. The sentinel moves that answer into the index, where both dialects
test it identically.
On GL nothing about the sampled result changes — the same slot resolves to the
same handle to the same texel. The SSBO read simply happens one stage later,
and `flat` keeps it one scalar load per primitive rather than per fragment.
Also: RenderBootstrap has been loading mesh_modern without common.glsl since V2,
which cannot have linked — `ACDREAM_UBO_SET` sits inside a layout qualifier
there. The UI Studio path is the only caller. One argument, same pair, same way
WorldRenderComposition has always loaded it.

feat(render): draw the retained UI on Vulkan, and fix the pass it exposed
Campaign V slice V6d, commit 3 of 3 — the evidence commit, which turned out to also be a bug-fix commit.
VulkanBringUpHost now builds a real UiHost and DebugLineRenderer on the Vulkan device and draws them after the V6c verification scene, in their own single-sampled load/store passes against the backbuffer — the same shape the GL client's HUD phase has. Nothing in the retained stack is backend-aware: UiRoot walks a real widget tree, each widget draws through UiRenderContext, and UiHost.Draw brackets it with TextRenderer.Begin/Flush. What it cannot be is the game's own UI, because the retail tree is built from LayoutDesc and DAT chrome by TextureCache, which stays a GL type until V4t; the sprites here are generated instead. The widget rectangles are authored at known pixel offsets from the top-left and nothing is mirror-symmetric, so a wrong Y flip would put the title bar at the bottom.
The frame this produced was wrong, and usefully so. Whole runs of the debug-line figure were missing. Vulkan's rasterization-order guarantees are scoped to one render-pass instance; between two instances writing the same attachment there is no implicit ordering, and that includes a multisample RESOLVE, which is part of the render pass and therefore equally unordered against what follows. TransitionBackbufferForRendering emitted its acquire barrier once per frame and returned for every pass after the first, so the second and third passes raced the first one's resolve. V6c's frame had exactly one backbuffer pass and could not see this; V6d's has three. A later backbuffer pass now gets a colour-attachment dependency instead of nothing, and keeps ColorAttachmentOptimal as its old layout rather than Undefined, which would have licensed discarding everything drawn so far. Every line renders continuously afterwards.
Inspection of artifacts/vk-ui/vulkan-bringup.png against the authored layout, by pixel probe:
The header panel is authored at (24,18), 420x96. Its tiled chrome fills exactly x 24..443 and y 18..113 — one pixel outside on any edge is the clear colour. The tile's lit edge appears at the top and left of every cell, so texture row 0 lands at the top and the V axis is not flipped. Both labels read left to right, right side up, through the font-coverage branch. The nested panel's border samples exactly (153,191,255) against an authored (0.6,0.75,1.0), unblended — the untextured branch is bit-exact. The badge sprite is authored at (460,58), 64x64, and its gradient starts at x=460 with the clear colour at 455 — the RGBA-modulate branch, sampling a table slot. The two debug-line segments land on their computed screen coordinates. All three fragment branches, the pixel-to-NDC mapping, the top-left origin, straight-alpha blending and table sampling are therefore all confirmed on Vulkan, which is everything the offline GL gate confirms about the same code on GL.
The plan's V6 milestone is amended rather than claimed: "full game frame on Vulkan" is not reachable while V4c/V4d are parked and the world renderers and TextureCache are still raw GL, so V6 delivers the backend plus the two renderers that can use it today. The accumulated user-gate table gains a V6d row for the paperdoll/appraisal viewport sprite — the one retained-UI texture the offline scene never draws, on a slice that changed how every UI texture is sampled.

Campaign V slice V6d, commit 2 of 3. TextRenderer and DebugLineRenderer were the only two renderers speaking the RHI, and both refused any device that was not a GlGpuDevice. They now refuse nothing: this is the first production rendering acdream can do on Vulkan.
Three things had to go.
The loose uniforms. debug_line declared uView and uProjection separately and DebugLineRenderer set them straight against the compiled GL program, because the pinned push-constant block carries one combined matrix and IGpuPassEncoder has no verb for arbitrary named uniforms. That was never portable — Vulkan has no default uniform block at all — so the shader converged on uViewProjection and Flush multiplies on the CPU. System.Numerics is row-vector convention while GLSL reads the floats column-major, which transposes, so the CPU equivalent of the old per-vertex uProjection * uView is view * projection. The product now rounds once per frame rather than once per vertex; these lines only draw when collision wireframes are switched on, so the offline gate sees nothing of it. ui_text's uScreenSize became the block's two spare scalars, uParamA and uParamB, with the same two divisions and the same NDC mapping around them.
The sampling mode. uUseTexture selected between font coverage, RGBA modulate and flat colour, and no field of the 96-byte block means that. It did not need one: which of the two texture-table slots is assigned IS the mode. uTextureIndexB assigned means a single-channel coverage source, uTextureIndexA assigned means an RGBA colour source, neither assigned means the vertex colour alone. GpuTextureSlot.Unassigned is already a loud sentinel for exactly this kind of question, and both branches guard so it never reaches a sampler. That also retired the 1x1 white fill texture: DrawFill routed solid quads through the sprite bucket relying on white times colour, and the untextured branch produces the same value with no texture at all. Multiplying by 1.0 changes no bits, and the gate agrees.
The texture binding. The classic glActiveTexture/glBindTexture path survived V4a because DrawSprite takes an arbitrary texture from sixty-odd widget call sites. But TextureCache had already registered every one of those into the device's table — the classic path was consuming the raw GL name that registration also produced. The UI's currency is now UiTextureTableHandle, a one-based table index whose zero is the same "no texture" every widget already guards on; a raw slot index would have turned all of those guards into silent false negatives, since slot 0 is perfectly valid. One-based rather than the slot itself because GpuTextureSlot is internal to the pinned contract while UiRenderContext.DrawSprite, TextureCache.GetOrUploadRenderSurface and a dozen widget properties are public, and neither publishing a contract type nor converting the retained UI to internal belongs in this slice.
Two consequences worth stating. The two backends disagree about what a 2-D table entry is — GL reconstructs a sampler2D from the bindless handle, Vulkan reads layer 0 of its sampler2DArray descriptor array — and ACDREAM_SAMPLE_2D is the one place that lives. Keeping GL on sampler2D is what leaves the UI's textures exactly as they are, including the paperdoll/appraisal FBO colour texture, which is an externally-owned GL_TEXTURE_2D from the §7.1 transitional seam and cannot become an array before V4g. On the Vulkan side, sampled views are now always layered, which also removes a latent invalid usage V6c shipped: it registered a Type2D offscreen view into a descriptor array whose element type is sampler2DArray.
And one real fix. Sampling through the table means a bound sampler object overrides the texture's own parameters. Nearest-requested UI art used to get its point filtering from a glTexParameter applied before the bindless handle went resident, so registering it with the stock WorldRepeat sampler would have made every retail icon and dat-font glyph silently bilinear. Those now register with a nearest-and-repeat sampler.
Supporting moves: GlGpuDevice.CreatePipeline splices common.glsl the same way Shader does, since an RHI shader that reads the table needs the table declared; GlGpuPassEncoder binds the device's table with the pipeline, which is the GL analogue of Vulkan binding descriptor set 2 per draw, and has to be per-bind because every raw-GL world renderer puts its own privately-numbered table at that binding; and the encoder derives GL_MULTISAMPLE from the pass's SampleCount, which is where the retained UI's hand-rolled glDisable belonged all along. TextRenderGlStateScope is deleted — the encoder's ambient capture restored a strict superset of it — and its failure-safety test follows the guarantee to GlAmbientCapabilityState, which gains a fakeable seam and, with it, the multisample-dimension coverage #249 recorded as missing.

feat(render): let a pipeline name the colour format it renders into
Campaign V slice V6d, commit 1 of 3. The third contract amendment of the campaign, in the same shape as GpuBlendMode.InverseAlpha (V4c) and GpuVertexFormat.UByte4UInt (V4d): a slice met a wall the pinned contract could not express, and the fix is a reviewed field rather than a backend working around it.
Vulkan's dynamic rendering bakes the colour-attachment format into the pipeline. VkPipelineRenderingCreateInfo has to name it at creation, and a pipeline whose declared format disagrees with the attachment it is used with is undefined. GpuPipelineDescription named SampleCount and nothing else about the target, so slice V6c had no way to ask the question and hard-coded VulkanTextureFormatMapping.CanonicalColorAttachmentFormat for every pipeline it built. It recorded that as a real expressiveness gap rather than hiding it, and named this commit as the honest fix.
GpuPipelineDescription.ColorFormat defaults to Rgba8UnormRenderTarget, which the Vulkan backend already maps to the swapchain's B8G8R8A8_UNORM, so every pipeline written before the field existed keeps exactly the format it was getting. GL ignores the field entirely: a GL framebuffer carries its own attachment formats and a program binds to whatever is attached, so there is nothing for the GL backend to declare. The substitution that makes an offscreen Rgba8UnormRenderTarget resolve to the swapchain's byte order stays — it is what lets a backbuffer pipeline and an offscreen pipeline share one description, and it is invisible above the API because an image is sampled through its format's component mapping.
The contract test asserts both halves that matter: the default is the render-target format (so nothing moves), and the field is really settable (so naming it is not decoration).

feat(render): Campaign V slice V6c - SPIR-V, pipelines, passes, and a Vulkan frame that draws
The last of V6's three commits, and the one that makes the backend render. Plan sections: 4.5 (pipelines and the persisted cache), 4.6 (shaders and the committed .spv), 4.7 and 3.3 (clip space, the Y flip and winding), 4.9 and 4.10 (swapchain format and the scissor convention), 4.11 (the probe shader V5 deferred), 5.4 (Target: null means the swapchain image, literally). WHAT RUNS. ACDREAM_RENDER_BACKEND=vulkan now renders a real scene through the whole RHI on the RX 9070 XT: 60,000-plus frames per twelve-second run, 4x MSAA resolving into a B8G8R8A8_UNORM swapchain, GPU timer scopes resolving, a screenshot taken through IGpuDevice.CaptureBackbuffer, and a clean CloseMainWindow exit with the allocator reporting three device-memory objects. WHAT IT DRAWS, AND WHY IT IS NOT THE GAME. V6's milestone is "a full game frame on Vulkan" and on this branch that cannot be the game's own frame. V4c and V4d are parked by 5.5.5 so the world renderers are still raw GL; and the two renderers that DO speak the RHI - TextRenderer and DebugLineRenderer, ported at V4a - both throw for any device that is not a GlGpuDevice, because their loose uniforms and their classic texture-unit sprite binding have no home in the pinned contract yet. Converting them is a V4-class change with its own GL pixel gate, outside this slice's file list. So the backend is exercised through the contract by a scene of our own, and it is not a toy. It uses a device-local mesh arena filled through the staging ring, instance and batch data written straight into mapped ring memory, an offscreen render target whose colour is registered into the global texture table and sampled by a later pass, a BC1 texture with a CPU-built mip chain beside an uncompressed one with a vkCmdBlitImage chain, one multi-draw-indirect covering five quads with gl_DrawID selecting per-draw batch data, a second pipeline with line-list topology bound mid-pass, dynamic cull/front-face/depth-write, push constants, timer scopes, and an MSAA colour attachment resolving into the swapchain image. ORIENTATION, BY INSPECTION. Slice V5's screenshot was a uniform clear and its orientation was right "by construction" - which a uniform clear cannot show. The scene is therefore deliberately asymmetric in both axes: a quadrant card that is red top-left, green top-right, blue bottom-left and white bottom-right, four differently tinted markers at four different corners, and an open L of lines whose short stub rises at its right end. The captured PNG reads correctly in every one of those, including a miniature of the same card in the bottom-right whose own quadrants are also the right way up. The negative viewport height, the front-face inversion and the capture path agree. THE SHADER TOOLCHAIN, AND WHAT IT FOUND. tools/compile-shaders.ps1 drives tools/ShaderCompiler, a small out-of-solution .NET tool over Silk.NET.Shaderc - the same shaderc glslc is built on, through the already-pinned Silk 2.23.0 family. glslc is preferred when a Vulkan SDK is present and reported when it is; neither this machine nor CI has one, and requiring a 500 MB manual install between a contributor and a working checkout is not a reasonable price for a build step. The GLSL sources stay the single source of truth: the Vulkan dialect arrives as a preamble injected after the #version line - ACDREAM_UBO_SET becomes "set = 1,", the texture table becomes a set-2 descriptor array with a required nonuniformEXT accessor, and the shared 96-byte push block is declared with each loose uniform name defined onto its member. The only edits to a shader BODY are mechanical and dialect-level: dropping default-block uniform declarations, which Vulkan GLSL has no such thing as, and assigning explicit varying locations BY NAME across a pair, because ordinal assignment would look identical today and silently swap varyings the first time an author reordered a line. Run over the eight production pairs, exactly one thing happened: none of them compiled, and every failure is a specific source-level fact belonging to a renderer-port slice that has not landed. debug_line needs uView/uProjection converged into one uViewProjection - two matrices are 128 bytes and the shared block is 96. mesh_modern and particle still pass a uvec2 bindless handle as a varying, which is V4t's GpuTextureSlot retype. sky has ten loose uniforms and wants a UBO. ui_text needs uScreenSize/uUseTexture/uTex. particle_mesh needs uTextureIndex to become uTextureIndexA. terrain_modern needs V4d-1's matrix convergence. mesh is the legacy pair with no RHI consumer at all. That inventory is committed as shaders.manifest.json, with each source's SHA-256 and the compiler's own message, and a test re-hashes it so an edited shader that never got recompiled fails a build rather than shipping a stale binary. vk_probe is the pair that does compile, and it is the shader 4.11 already asked for: V5 recorded "build one real pipeline from the committed .spv" as its single deliberate deviation because no toolchain existed. It is Vulkan-dialect only and no GL renderer draws with it, so it forks nothing; it retires when the ported world renderers become the backend's own proof. DESCRIPTORS. Sets 0 and 1 are DYNAMIC buffer descriptors bound per flight slot, so a per-draw range change costs a dynamic offset in vkCmdBindDescriptorSets rather than a vkUpdateDescriptorSets in the hot path - which is what keeps 4.4's zero-writes-per-frame property true for buffers as well as for textures. Ten dynamic storage descriptors is above Vulkan's guaranteed minimum of four, so it is a real requirement rather than a free choice, it fails loudly at layout creation on a device that cannot serve it, and V9's lavapipe row must confirm it. Unused bindings point at a shared dummy range so there is ONE set layout and one pipeline layout; that is why binding a second pipeline mid-pass costs nothing and disturbs neither the descriptors nor the push constants. THE ONE MAPPING FUNCTION. VulkanViewportMapping holds the whole coordinate reconciliation: negative viewport height, the front-face inversion that pairs with it, and - separately - the scissor flip, which the viewport sign does NOT perform. The V3 audit flagged that as a concrete V6 acceptance item and it is the subtle one: vkCmdSetScissor is always top-left-origin, NdcScissorRect emits GL bottom-left rectangles, and getting it wrong clips a doorway aperture from the wrong edge in a scene that has one. Clip space needs nothing, as 4.7 concluded: the cameras already build [0,1]-convention projections. CONTRACT GAP, RECORDED NOT PAPERED OVER. GpuPipelineDescription cannot name its colour-attachment format, and Vulkan bakes that into a pipeline. Offscreen targets therefore adopt the swapchain's B8G8R8A8_UNORM rather than a literal RGBA order - invisible above the API, because an image is sampled through its format's component mapping and the one CPU readback swizzles explicitly. The honest fix is a colour-format field added in a reviewed contract commit, exactly as GpuBlendMode.InverseAlpha and GpuVertexFormat.UByte4UInt were added when V4c and V4d met the same wall. It is documented at VulkanTextureFormatMapping.CanonicalColorAttachmentFormat. The pipeline cache is persisted to the cache directory and validated by its 32-byte header against this device's vendor, device and cache UUID before use. Drivers are required to ignore incompatible blobs, but "required to" is a poor foundation for something that runs before anything else in the process, and the check costs 32 bytes of comparison. Two consecutive launches report "cold" then "reused". Gates: Release build clean; App suite 4056 passed / 3 skipped (4037 at V6b plus 19 new); offline pixel gate PASS at a differing fraction of 5.15e-05 with a same-commit control immediately after it at 2.84e-05 - 29 and 16 pixels of 563,200, the same class of ambient variation the campaign's 15-23 band records, and roughly 19x under the 0.001 threshold on a commit that changes no GL code path. Validation layers could not be run: this machine has no Vulkan SDK, no HKLM\SOFTWARE\Khronos\Vulkan\ExplicitLayers key, no VK_LAYER_PATH and no VkLayer_khronos_validation.json anywhere on disk. Plan 7 already requires one validation-clean run at V7; it needs the SDK installed first and is reported rather than assumed here. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

feat(render): Campaign V slice V6b - Vulkan textures, mips, samplers and the descriptor table
The second of V6's three commits: everything the fragment stage samples. Plan sections 4.3 (textures and mip generation) and 4.4 (descriptors). The descriptor table is the piece that retires GL_ARB_bindless_texture. One update-after-bind, partially-bound, variable-count combined-image-sampler array of 16384; registration appends exactly one vkUpdateDescriptorSets and nothing is written at draw time, so steady state is zero descriptor writes per frame. A slot is a (view, sampler) pair, exactly like a bindless handle, which is why the CPU data model needs no change at all - GpuTextureSlot already carries the index and V2 already moved every batch onto it. Eviction is retirement-gated and the slot is scrubbed on the way out. Returning a slot the moment a texture is deleted would let the LRU alias a live draw onto a new texture, so the release is filed through the ledger; and when it runs the slot is first overwritten with the default 1x1 white. A stale view descriptor sitting in a partially-bound array is legal right up until something reads it, at which point it is a use-after-free with no error attached. Writing the dummy makes that impossible rather than unlikely. The CPU block-compression codec is the slice's other substantial piece, and it exists because Vulkan cannot blit into a compressed image. DAT surfaces arrive as DXT1/3/5 with no mips, so the chain has to be decoded, box filtered and re-encoded here. That is not merely a substitute for the missing blit: the GL path calls glGenerateMipmap on compressed array textures, whose result is explicitly implementation-defined, so this is the first time that part of the pipeline has had a defined answer. Two properties matter more than quality, and both are tested. It is deterministic - integer arithmetic end to end, endpoints from the block's bounding box, nearest-palette selection, no dithering and no iterative fit - because the offline pixel gate compares captures from separate processes and a chain that varied run to run would make every textured surface look like a regression. And it preserves BC1's one-bit cut-out: a block containing any texel below the alpha threshold is encoded in three-colour mode, because retail's foliage and grates ARE that mode and quantising those texels to an opaque colour would fill in every leaf. Plan 4.3's escape hatch stands if quality ever trips a gate: store the affected textures as RGBA8 and blit their mips. Uncompressed images do take the blit chain, added to the upload queue. Each source level moves to TRANSFER_SRC for its blit and back to TRANSFER_DST afterwards; leaving the chain in mixed layouts would be one barrier cheaper and would then force the batch's final shader-read transition to name a different old layout per level, so ending every level the same way is what keeps that transition one barrier per image. The upload queue now records the layout each image is in on ENTRY to a batch rather than always naming UNDEFINED. UNDEFINED lets the driver discard existing contents, which is right for a fresh image and wrong for the incremental array-layer fills that mirror ManagedGLTextureArray - discarding there would erase every layer uploaded earlier. Render targets are single-sampled per the contract and carry SAMPLED usage alongside COLOR_ATTACHMENT, so a paperdoll or appraisal view can be registered into the table and drawn by the retained UI the moment its pass ends. VulkanBackbufferAttachments owns the two attachments the swapchain does not: the multisampled colour scratch that resolves into the swapchain image, and the transient depth/stencil. Both are TRANSIENT_ATTACHMENT because nothing reads either after the frame. Stencil is not optional - issue #117's portal punch needs the aspect, which is why the V5 gate prefers D32_SFLOAT_S8_UINT over a depth-only format. Every format stays UNORM, and that is the V3 audit's finding rather than a default. The plan previously specified an sRGB swapchain "matching the GL FramebufferSrgb contract"; that contract does not exist, the renderer is plain UNORM end to end, and shipping _SRGB would have brightened every frame and passed silently until V7. VulkanPipelineLayouts is extracted from V5's capability probe rather than written beside it, and the probe now calls it. The probe's whole value is proving the layouts the live backend builds can be built on this device; two similar-looking definitions would have quietly ended that the first time one of them changed. Gates: Release build clean, App suite 4037 passed / 3 skipped (4014 at V6a plus 23 new), offline pixel gate PASS against the parent baseline at a differing fraction of 4.26e-05 - 24 pixels of 563,200, one above the campaign's recorded 15-23 same-commit noise band and about 23x under the 0.001 threshold, on a commit that changes no GL code path.

feat(render): Campaign V slice V6a - Vulkan memory, buffers, rings and the frame timeline
The first of V6's three commits, and the half of the Vulkan backend that has nothing to do with drawing: where memory comes from, how per-frame data reaches the GPU, and what makes it safe to reuse either. Plan sections: 4.2 (bindings layer and the no-VMA decision), 4.3 (memory: arena, staging ring, per-frame data), 4.8 (sync and the frame). The allocator is hand-rolled, roughly as 4.2 sizes it. Silk ships no VMA, and a third-party binding would be a native binary to carry across win-x64, linux-x64 and CI lavapipe for an allocation profile that is genuinely tame: two mesh arena buffers, one staging ring, a per-flight ring buffer each, a few render targets and a texture pool. What a custom allocator buys instead is exact accounting - every byte is attributable to a memory type and a block - which is what GpuMemoryTracker will want and what VMA would obscure. Placement, block policy and heap choice are pure types with no Vulkan handle in sight: VulkanMemoryBlockFreeList is first-fit with coalescing on release, VulkanMemoryTypePool decides when a request is large enough to warrant a block of its own, and VulkanMemoryTypeSelection maps each GpuMemoryResidency onto a preference order of property masks. VulkanDeviceMemoryAllocator turns their answers into vkAllocateMemory and one persistent vkMapMemory per host-visible block. That split is deliberate: an allocator's real failure modes are arithmetic - a mis-coalesced neighbour, an alignment that eats a block's tail, a double release that quietly corrupts the used-byte count - and arithmetic does not need a GPU to be wrong. Twenty-two tests cover exactly those. The HostWritable row of the selection table is the campaign's CPU win stated as data. It prefers a memory type that is both DEVICE_LOCAL and HOST_VISIBLE - resizable BAR, present on the RX 9070 XT - so per-frame data is written once, straight into memory the GPU reads, and falls back to ordinary host-visible coherent memory when no such type exists. GpuCapabilityRecord's SupportsPersistentlyMappedRings is the first capability that is true on this backend and false on GL. Mapping is per block, never per allocation, because Vulkan permits a memory object to be mapped once - mapping per buffer would need one VkDeviceMemory per buffer, which is precisely the allocation-count explosion the design exists to avoid. VulkanRingBufferState is markedly simpler than its GL sibling, and the difference IS the point. GlRingBufferState has to track a dirty watermark and prove its upload never overlaps an in-flight read, because a ring allocation there writes into a managed array that is later copied into a GL buffer. Here the allocation hands back memory the GPU reads directly: there is no upload step to track. What is left is a cursor. VulkanUploadQueue accumulates transfers rather than issuing them, for two reasons that both come from Vulkan rather than from taste: copies must be recorded into a command buffer, and they must be recorded outside a dynamic-rendering block. So requests queue and drain at the one moment both hold - immediately before a pass begins - which is the direct analogue of the GL backend's flush-before-every-draw discipline at the granularity Vulkan needs. The drain emits one batched buffer barrier for the whole batch, one of the four to six 4.8 budgets per frame. Staging exhaustion falls back to a temporary dedicated buffer retired through the ledger. Section 4.3 already specifies that for oversized uploads; extending it to "the ring is full of unretired frames" is the same shape and is a policy rather than a workaround - the transfer stays correct and ordered, it just costs one allocation. VulkanFrameFlightController is the mechanical port 4.8 promised. GL's array of fences becomes one timeline semaphore whose value is the frame serial, "has this slot retired?" becomes "is the counter at least serial minus two?", and the SortedDictionary retirement ledger keeps its keys because those keys were already frame serials. One subtlety is worth stating: a release is filed against the frame currently being RECORDED, not the last one completed, because commands already recorded into the open frame may still read the resource. A test pins that, since getting it wrong frees memory a pending command buffer reads and the symptom would appear somewhere else entirely. Frame acquire ordering is the other subtlety. TryBeginFrame waits on the flight slot BEFORE acquiring its swapchain image, so the slot's acquire semaphore is provably idle - signalling a semaphore a pending submit still waits on is the classic Vulkan deadlock. When the acquire fails the serial is still signalled through an empty submit, because a serial that never completes makes every later frame wait forever. The device is a partial class split along the V6 commit boundary: everything here is memory and frames, while textures and the descriptor table (V6b) and pipelines, passes and readback (V6c) throw with the slice named rather than returning something that fails later and further away. Nothing constructs this device yet - VulkanBringUpHost still presents its clear colour - so the GL path executes not one new statement. VK_EXT_debug_utils naming arrives with the allocator rather than at V6c, because every resource wants a name from birth and the campaign has already spent days on defects only visible from outside the API. It stays optional: absent extension means every call is a no-op and no call site checks. Gates: Release build clean, App suite 4014 passed / 3 skipped (3981 baseline plus 33 new). One Issue181WallPressEquilibriumTests failure in the full run is the known #250 zero-allocation flake and passes on a single run. Offline pixel gate against the parent is a tripwire here - the backend is dark and no GL code path changed - and is reported with the slice. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

feat(render): Campaign V slice V5 - Vulkan bring-up, dark
Instance, physical-device selection, logical device, queues, swapchain, and the three-layer capability gate, behind ACDREAM_RENDER_BACKEND=vulkan. Nothing of the game renders through it. OpenGL stays the default and the only live backend until V10, and with the variable unset or set to gl the GL path executes not one new statement. The shape of the slice. Plan §4.11 asks the Vulkan gate to mirror the GL one exactly - passive record, active probes, an Evaluate producing operator-facing sentences, NotSupportedException into Program.cs's exit-code-4 contract, and an atomic JSON report. The harder question was where to put the seam, because a capability gate is precisely the code you cannot exercise on the machine that already passes it: this box has one discrete GPU, so device ranking, the split- queue path, an sRGB-only surface, a minimised window and a device missing descriptorBindingVariableDescriptorCount are all unreachable by running the client. So every decision the gate makes is a pure function over plain records, and the Silk interop layer only has to be right about which Vulkan field feeds which property. VulkanPhysicalDeviceSelection ranks candidates, VulkanExtensionSelection does the required-versus-optional set arithmetic, VulkanSwapchainConfigurationFactory chooses format, present mode, image count, extent, usage, transform and composite alpha, VulkanSwapchainRecreationPolicy classifies every acquire and present result, and VulkanCapabilityRequirements.Evaluate turns a captured record into failure sentences. All of it is unit-tested with no driver, no device and no window. This commit is the integration of that work onto the post-revert tree. The V5 branch was written on |

fix(diag): resolve the multisampled backbuffer before reading it
Every automated pixel gate and every blank-world verdict in Campaign V is produced by FrameScreenshotController reading the default framebuffer with glReadPixels. The window is created with the quality preset's MSAA sample count, so that framebuffer is normally 4x multisampled -- and glReadPixels against a multisampled read framebuffer is undefined per the GL spec. The instrument the campaign has been using to decide "did the world render?" rested on an operation with no specified result. That is not a theoretical complaint. The blank-world investigation spent several rounds unable to tell "the renderer drew nothing" apart from "the readback did not return what the renderer drew", and it took an out-of-process desktop grab to separate them. A gate cannot arbitrate a rendering defect while its own read is unspecified. So the capture resolves first: when the default framebuffer is multisampled it blits the whole colour buffer into a single-sampled RGBA8 framebuffer with identical rectangles and GL_NEAREST -- the defined resolve -- and reads that. A single-sampled default framebuffer keeps the original direct read, so non-MSAA captures stay byte-for-byte what they were. The blit disables and restores the scissor test, because a blit is subject to it and a frame that left a rectangle armed would otherwise resolve only part of the image; that is the same self-contained-GL-state rule the render passes follow. The resolve target is created and destroyed per capture -- captures are rare, and a cache would have to track resize and context teardown for no gain. GlGpuDevice.CaptureBackbuffer had the identical undefined read. It now routes through the same path rather than being a second instrument to keep sound. The IDefaultFramebufferSurface seam grows the draw binding, the sample count, and the resolve operations, so the bind/query/blit/read/restore order stays assertable without a GL context; two new tests pin the resolve order and the resolve target's release on a failing read. Gates: Release build green. App tests 3,866 passed / 3 skipped. Offline pixel gate against |

test(render): add blank-world attribution apparatus and a post-world GL sample
Investigating the V4c connected blank-world failure needed two things the tree
did not have: a way to tell whether a blank run is caused by the binary under
test, and a way to see GL state at the end of the world phase rather than only
at the frame clear. Both are apparatus only - no production behaviour changes,
and the new probe emits nothing unless ACDREAM_PROBE_GLSTATE=1.
run-blank-world-ab-probe.ps1 interleaves two client builds over the repeat
gate's exact connected route and reports the blank rate per arm. This exists
because the blank rate is not stable across blocks: the same V4c binary
measured 3/10 in one block and 7/10 in another an hour later, so a block of A
followed by a block of B confounds the change with whatever else moved on the
machine in between. Strict alternation shares that drift between both arms.
Run against V4c and its parent it reported 4/5 versus 0/5 (Fisher exact
p~0.024), which is what established the defect follows the binary.
run-blank-world-surface-probe.ps1 grabs the composited window off the desktop
with CopyFromScreen at the same moment the client writes its own screenshot.
No instrument inside the GL context can separate "the renderer drew nothing"
from "the read did not return what the renderer drew", because both live on
the same side of the readback; an independent witness can. It is what showed
the two disagree - see below.
EmitPostWorldGlStateIfChanged is a second sample of the existing [gl-state]
snapshot, taken at the end of the normal-world phase. The existing tripwire
samples just after the clear phase's RestoreFrameDefaults, so it can only
observe state that survives from one frame into the next, and the draw
framebuffer is restored by no frame-global path. A binding established during
the world phase and put back before the next clear was therefore invisible to
it. Sampling at both ends brackets the phase.
What the apparatus established, recorded here rather than in the campaign doc
because no fix landed and the doc's re-land conditions are unchanged:
* The world draw path is not what is missing from the frame. On a blank run
the desktop grab shows the atmosphere clear over the whole viewport and the
complete retained UI - chat, radar, toolbar, vitals - in their normal
places, with every 3-D surface absent. Terrain and sky are still raw GL and
V4c does not touch them, so whatever V4c disturbs is shared, not per-
renderer.
* The CPU issues the same work either way. With ACDREAM_PROBE_FLAP=1 the
render signature is identical between blank and rendered runs: same
RetailPViewInside branch, same resolved root, terrain drawn, 3,331 outdoor
statics and 6 live dynamics dispatched.
* Both GL-state samples read fbo=0, full 1280x720 viewport, scissor off and
err=0x0, byte-identical between blank and rendered runs.
* The client's own capture disagrees with the screen. glReadPixels returns
uniformly RGBA(0,0,0,0) on a frame the desktop grab shows as fog plus UI.
The default framebuffer is 4x multisampled (SampleBuffers=1, Samples=4 in
the capability report) and glReadPixels against a multisampled read
framebuffer is undefined per the GL spec, so the gate's blank-versus-
rendered verdict rests on undefined behaviour in both directions.
Baseline App tests 3,864 passed / 3 skipped, unchanged.

fix(render): map the GL frame ring instead of glBufferSubData
Campaign V's V4c and V4d were reverted because the connected world went blank
roughly one launch in three, with no GL error anywhere and every added CPU-GPU
sync point suppressing it. The plan's section 5.5 records the best-supported
cause and makes this change binding before either slice may re-land: the frame
ring performed 10-40 partial glBufferSubData updates per frame into a buffer
object that already-submitted same-frame draws were still reading, and the
offline path that passed every gate issues only 2-4. That is the offline versus
connected axis, stated exactly.
A partial glBufferSubData into an in-use buffer does not have one defined
implementation. The driver may stall, may rename the whole data store and copy
the untouched remainder forward, or may route the write through an internal
staging copy, and which one it picks is a heuristic fed by the update pattern.
glMapBufferRange with GL_MAP_WRITE_BIT, GL_MAP_UNSYNCHRONIZED_BIT and
GL_MAP_INVALIDATE_RANGE_BIT removes the guess. The three bits say "I am writing
this range", "I am overwriting all of it", and "nothing in flight reads it" -
which is the ring's actual invariant rather than something the driver has to
infer. GlGpuBuffer.WriteRangeUnsynchronized is that write, and the ring no
longer calls Upload at all. Upload itself stays, synchronized, for the writers
whose ordering really is the driver's job: the mesh arena and texture staging.
The unsynchronized bit is an assertion, so the two invariants behind it are now
enforced rather than merely true. Across frames it belongs to
GpuFrameFlightController, which waits on a slot's fence in BeginFrame before
GlRingBufferState.Reset rewinds that slot. Within a frame it belongs to the
allocation cursor, which only moves forward, so each flush covers bytes strictly
above every byte already flushed. GlRingBufferState now carries the flushed
high-water mark explicitly and refuses a write below it, so a future change that
reused ring bytes mid-frame fails loudly here instead of producing an undefined
read on the GPU. MarkDirty is internal for the same reason AlignUp already was:
the guard is unreachable through Allocate by construction, and proving it fires
needs a direct call.
The texture handle table moved too, because it is the only other buffer this
backend rewrites while the frame's own draws are in flight, and leaving one
partial glBufferSubData in the pre-draw flush would have left a live instance of
the same mechanism sitting inside the very function this change exists to fix.
It cannot use the ring's single merged span: two registrations in one frame can
land on slots 5 and 50 with forty-four live slots between them, and a mapped
invalidating write over that whole span would let the driver discard live
bindless handles a submitted draw is reading. GlDirtySlotRuns therefore drains
the table one run of consecutive dirty slots at a time. Every slot in a run is
safe on its own terms: RegisterTexture writes a slot fresh from the allocator
that no batch has ever indexed, and ReleaseTextureSlot's zeroing write already
runs inside a retirement callback, after the fence covering every frame that
could still reference it.
Nothing about renderer-visible behaviour changes. No renderer, no shader and no
CPU data layout is touched; only how the same bytes reach the same buffers.
SupportsPersistentlyMappedRings stays false, since a map-per-flush is not a
persistent mapping - its comment was rewritten because it claimed the backend
never writes into mapped memory, which is no longer true.
Gates. Release build green. App tests 3,862 passed / 3 skipped, against a
3,846 / 3 baseline measured on this tree plus the 16 tests added here (one
full-suite baseline run failed WorldRenderFrameBuilder's runtime-root-source
test, which passes alone and passed on the rerun - a pre-existing ordering
flake, not a regression). Offline pixel gate against
