fix #270 closeout: strip investigation probes; close the issue
User-verified: casting fixed (exhaustion-edge gate) and monster attack animations restored (spawn settle placement + lost-cell retry). Final session evidence: 14/15 spawn settles grounded; Falling-refusal spam collapsed 2,954 -> 15 transient pre-settle lines. Strips the [UM-ACT]/[MT-FAIL]/[SPAWN-PLACE]/[remote-edge] probes, the MotionInterpreter.DiagnosticGuid plumbing, and the two throwaway probe tests (motion-table attack sweep, vitae color dump - both findings are recorded in ISSUES/research). Complete Release suite: 10,030 passed / 5 skips / 0 failures. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

fix #270: run retail spawn placement at remote-body creation - standing monsters' attack animations restored
The [MT-FAIL] probe caught combat-stance monsters constantly failing to dispatch 0x40000015 (Falling): their bodies were airborne-flagged while standing. contact_allows_move (0x00528dd0) requires Contact+OnWalkable and silently refuses every action animation for an airborne mover - a spawned-standing monster's swings never played until it first moved. Retail never has this state: CreateObject spawns run the placement transition (CPhysicsObj::SetPosition -> SetPositionInternal 0x00515330), which establishes CONTACT/ON_WALKABLE from the floor at spawn. Our remote creation seeded a raw position with no placement. SeedRemoteSpawnPlacement mirrors RemoteTeleportPlacement: engine placement resolve (Setup-derived cylinder, TS-46) + the verbatim CommitSetPositionTransition, wired at BOTH RemoteMotion creation sites (UM-triggered creation - so a first-ever-UM attack animates in the same packet - and ordinary first-UP creation). Unplaceable results leave the body airborne exactly like a failed retail placement. Also adds the [UM-ACT] (wire action items + stamp-gate verdict) and [MT-FAIL] (refused animation dispatches) probes, riding ACDREAM_DUMP_MOTION=1, which are what convicted the body state. Complete Release suite: 10,032 passed / 5 skips / 0 failures. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

fix(physics): #265 landing-bounce family - retail check_contact seed + velocity-free landing commit
Retail jump landings BOUNCE: the floor touch records both a contact plane (grounding) AND a collision normal (collided_with_environment), and handle_all_collisions reflects the unmodified impact velocity off it at 5% elasticity (v += -(v.n)(elasticity+1).n, DEFAULT_ELASTICITY 0.05 @0x007c6a7c). Our transition already recorded both facts; the bounce was suppressed by the AD-25 adaptation stack in the per-tick commit: a Velocity.Z<=0 landing gate (needed because the resolver glued ascending movers to the ground) plus a landing Velocity.Z=0 hand-zero whose stated purpose was making the reflect a no-op. Downhill glided instead of bouncing, flat-ground landings had no pop, and uphill jumps flapped between grounded/airborne against the animation machine. Three retail mechanisms replace the stack: - check_contact (0x0050f5b0) seeding in ResolveWithTransition: a body in CONTACT seeds the transition's contact only while v.contactPlane.N <= 0.0002; moving away seeds the last-known plane alone (get_object_info 0x00511cc0). Ascending jumps therefore run contact-free (ballistic, no glue) - the gate's reason-for-being is gone. The plane requirement is strict: Contact-without-plane is unrepresentable in retail. - SetPositionInternal-shaped commit (0x00515330, byte-read end-to-end, velocity-sign-FREE): contact purely from the transition's contact plane, HitGround on the airborne->walkable edge, HandleAllCollisions with unmodified impact velocity. Whole commit gated on Ok && candidateMoved (retail pc:283657 skips SetPositionInternal entirely when the candidate did not move) - a standing body's contact state is never re-derived, which is what keeps rest bit-stable (AD-41 updated). - Byte decodes: gate override state&0x800000=Sledding, zero branch state&0x20000=Inelastic, reflect strictly dot<0 - our port already had all three correct. Settle: real landings (>=0.25 m/s) bounce and decay geometrically; smaller impacts are consumed by retail's unconditional small-velocity zero, so standing never micro-bounces. Re-baselines documented in place: landing-survival pin measures decay post-settle; LiveCompare_Tick0/376 pin the new IsOnGround=false on zero-move ticks (captured true was the retired seed echo; tick 376's captured body carries an 11.8 m/s grounded velocity from the deleted get_state_velocity-overwrite era); de-overlap fixture now carries the plane real grounded bodies always have. New pins: LandingBounceSeedingTests (ascent no-seed, rest keeps contact, strict plane, slope 5% reversal + tangential preservation, Sledding override). Investigation + implementation record: docs/research/2026-07-30-landing-bounce-family.md. Complete Release suite: 10,031 passed / 5 skips / 0 failures.

fix(ui): #267 character panel reflects vitae/buffed skills and attributes
Retail CACQualities::EnchantAttribute (0x00594570), EnchantAttribute2nd (0x00594670, already ported for #6), and EnchantSkill (0x005947b0) are the three enchantment-composition functions the Character window's Attributes and Skills tabs depend on. Primary attributes never reference the vitae singleton in retail (only Attribute2nd/Skill do) — confirmed directly from the decompiled function bodies, not assumed. EnchantmentMath.GetMod gains requiredType/includeVitae parameters (default to the prior behavior) so a numeric StatMod key collision across domains (e.g. key=1 is both Strength and MaxHealth) can't leak a buff into the wrong computation. Spellbook.GetAttributeMod/GetSkillMod and LocalPlayerState.GetEffectiveAttribute/GetEffectiveSkill/ GetSkillVitaeModifier wire the retail chain through to the panel. CharacterSheetProvider now reports the effective value as the main number and CharacterSkill.CurrentLevel is no longer an alias of BaseLevel (this also activates the previously-dead SkillValueColor buffed/debuffed row coloring). CharacterStatController's footer-title parenthetical is cited from gmAttributeUI::DisplaySelectionFooter_Attribute (0x0049d280) and gmSkillUI::DisplaySelectionFooter_Trained (0x0049b860) + SkillInfoRegion::GetVitaeModifier (0x004f0fa0): skills show up to two segments (vitae's own contribution, then the buff-only residual), while vitae-immune attributes show at most one; no parenthetical when the delta is zero. The panel now refreshes on Spellbook.EnchantmentsChanged, not only raw property/attribute updates. Core goldens cover the user-reported 33% vitae example (303->203, "(-100)" exactly), buff+vitae composition, and the attribute vitae-immunity finding. Provider/controller tests cover the full row-click -> footer-title path and live refresh. Full solution suite passes with zero failures. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

fix(physics): movement-parity fixes - adjusted catch-up cap, autorun retail semantics, AP-30 retired
Ports CMotionInterp::get_adjusted_max_speed (0x00527D00, byte-decoded: bare rate unless RunForward; forward_speed x 4.0 when running; current_speed_factor proven a ctor-constant 1.0 at 0x00528C34) and swaps all five interpolation catch-up call sites to it - retail's fUseAdjustedSpeed_ static (.data 0x0081F418 = 1) makes this the live branch, so standing/walking remotes now catch up at ~2x runRate instead of 4x too fast (the #41/#165 presentation family). Autorun now hard- forces Run for its duration and cancels on every fresh forward press (CommandInterpreter::HandleNewForwardMovement 0x006b3d60 is literally SetAutoRun(0,1)); the old test pin codified the divergence. AP-30 retired: retail Frame::is_equal genuinely uses the 0.0002 epsilon - the row recorded a non-divergence. Three catch-up test pins re-baselined to retail semantics with citations. Full Release suite 9,983/0. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

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.

feat(ui): port retail UIElement_Dragbar so authored drag strips move their windows

The combat bar and spell bar could not be moved at all: their window mounts Draggable=false (correct - retail never whole-surface-drags them) and the authored move mechanism was missing. Retail registers element class 2 as UIElement_Dragbar (Register @ 0x0046C840); a press inside it calls UIElement::StartMovement on its parent window (StartMouseMoving @ 0x0046C760) and release calls StopMovement (@ 0x0046C7C0). The combat/spell bar layout (LayoutDesc 0x21000073) authors exactly one such element - a 600 x 5 strip along the top edge, which is where the user expects the move cursor. The powerbar, vitals, indicators, radar, and examination layouts author dragbars too, so they all gain their retail handles from this one port. Our importer knew Type 2 by name but built it as a generic UiDatElement - ClickThrough decoration, so the strip never even claimed the pointer. Now: - UiElement.WindowMoveHandle marks an authored handle; the DAT factory sets it for Type-2 elements and opts them out of ClickThrough. - A left-press inside a handle subtree moves the handle's top-level window (the outer frame directly under the root - the mounted analogue of retail's dragbar parent) even when that window is not whole-surface Draggable. Edge-resize still wins; UiLocked still gates, matching the retail locked/fixed parent-flag check. - HoverWindowMove reports the handle so the window-move cursor shows over the strip - and only there - on non-Draggable windows. Four new tests: handle press moves a non-Draggable window and stops on release, hover shows the move cursor over the strip but not the body, UiLocked suppresses both, and the factory builds Type 2 as a pointer-claiming move handle.

fix(ui): UiField wrapped-line cache coherent with the text at mouse-hit time

Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
Fixes the crash the user hit twice today (captured in artifacts/coldeve-acceptance-20260729/crash-hunt.log): clicking into a multiline UiField - the examination window's inscription field - after the text had changed since the last draw threw an unhandled ArgumentOutOfRangeException from String.Substring and took the whole client down (UiField.MeasureRange <- HitChar <- OnEvent MouseDown). Root cause: _wrappedLines is a DRAW-side cache (rebuilt only in DrawMultiLine) consumed by the INPUT side (HitChar on MouseDown and drag-select MouseMove). Input events are pumped before the frame's draw, so a mutation (backspace, SetText, paste) followed by a click in the same pumped frame handed HitChar wrap lines describing the OLD, longer text; measuring those stale ranges ran past the end of the live string. Fix: text mutations now bump a version (the _text field became a private property so every existing mutation site participates without churn), the draw records which version its wrap lines describe, and HitChar proves coherence via EnsureWrappedLinesCurrent() - rebuilding with the last draw width when stale. Rebuilding rather than clamping keeps caret placement CORRECT against the live text, not merely non-throwing. Two inversion-sensitive regression tests reproduce the exact crash sequence (wrap long text, shrink without a draw, click); they throw without the HitChar coherence call. App tests 3,962 passed / 3 skipped (3,960 + 2 new). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

fix(interaction): port retail's wielded-item pickup rejection (Slice 4 F1)
Slice 4 made a remote character's wielded weapon selectable, which made the
pickup chain reachable end to end for the first time: SelectionPickUp on
another player's weapon captured identity, passed ValidatePickupTarget (which
checked only the Stuck flag and the small-item mask, and a MeleeWeapon clears
both), installed a real non-autonomous approach through
PlayerInteractionMovementSink, and then sent a pickup request the server
rejects. Retail does none of that.
ItemHolder::AttemptToPlaceInContainer @ 0x00588140 runs
AttemptToPlaceInContainer_IsItemLegal @ 0x005870C0 first, at 0x00588173 --
ahead of container legality, auto-merge, the container walk, and the only
CM_Inventory::Event_PutItemInContainer emitter
(ACCWeenieObject::UIAttemptPutInContainer @ 0x0058D680). IsItemLegal's arm at
0x005872B7 rejects `!ACCWeenieObject::IsOwnedByPlayer(item) &&
item->pwd._location != 0` with one local
ECM_UI::SendNotice_DisplayStringInfo(0x1a, ...), and
CPlayerSystem::PlaceInBackpack @ 0x0055D8C0 then withdraws the waiting slot it
had published (SetWaitingState(obj, 0) + SendNotice_EndPendingInPlayer at
0x0055D918). No request, no movement. acdream had never ported that arm; it
was harmless while wielded children were unpickable and stopped being harmless

feat(interaction): Slice 4 - equipped-child world picking
A click on a remote character's wielded weapon reported nothing. The picker was already correct: RetailSelectionScene publishes every drawn part under its own live-entity server GUID and RetailWorldPicker returns the weapon as the polygon winner. The failure was downstream eligibility - WorldSelectionQuery required TryGetInteractionEligibleRecord, whose _visible set admits LiveEntityProjectionKind.World only, so the winning hit was discarded. Retail has no such gate. Render::GfxObjUnderSelectionRay @ 0x0054C740 accumulates each hit under the drawn part's own physics-object id (CPhysicsPart::get_physobj_id @ 0x0050D490), and CPhysicsPart::Draw @ 0x0050D7A0 admits any drawn part whose physobj id is nonzero. An equipped item is a first-class CPhysicsObj with its own id and part array (CPhysicsObj::add_child @ 0x0050F870 via CSetup::GetHoldingLocation @ 0x005213F0). There is no parent redirection and no wielded-specific rule, so a click on a wielded weapon returns THE WEAPON'S GUID. PositionState.WIELDED is distinct from IN_CONTAINER (acclient.h:6802), so container suppression never hid a wielded selection either. LiveEntityRuntime gains two scoped predicates: TryGetAttachedProjectedRecord (a current Attached projection that is spatially projected) and TryGetPickEligibleRecord (that arm plus today's World visible-set arm, with the same WorldEntity.Id staleness recheck). TryGetInteractionEligibleRecord and the _visible set are deliberately NOT widened - they feed radar, auto-target, sticky/MoveTo establishment, and CombatAttackTargetSource, and retail's radar has no wielded blips. A regression test asserts an attached child stays out of that set while picking admits it. Marker anchoring had the twin problem. SmartBox::GetObjectBoundingBox @ 0x00452E20 pushes the picked object's OWN m_position - which for a child is the frame CPhysicsObj::UpdateChild @ 0x00512D50 recomposes each tick as Frame::combine(parent part frame, holding frame) - and CPartArray::GetSelectionSphere @ 0x00518B80 scales the authored sphere by that object's own part-array scale. acdream stores the PARENT's root in the child projection's Position/Rotation because the child's MeshRefs are parent-relative, which put the vivid brackets at the wielder's feet. The composed child root is already published per frame to EntityEffectPoseRegistry by EquippedChildRenderController.PublishChildPose, so selection now borrows it through an injected Func<uint, Matrix4x4?> wired in LivePresentationComposition beside the existing selection-sphere hook. There is no parent fallback: a child with no published composed root has no live frame this tick and no sphere. Its part-array scale comes from the spawn record, the same source EquippedChildRenderController.TryRealize reads, because an Attached WorldEntity carries the parent-derived pose rather than its own ObjScale. The sr_Use branch of RecvNotice_SmartBoxObjectFound @ 0x004E5AD0 guards ItemHolder::UseObject with `found->pwd._wielderID != SmartBox::player_id` at 0x004E5BE9 while still selecting and flashing. Equipped-child picking makes that click reachable, so the gate ships with it as IWorldSelectionQuery.IsWieldedByPlayer. CPhysicsObj::SetLighting @ 0x00511A80 is non-recursive, so the pulse lights the clicked object's own part array only - clicking a weapon never flashes its wielder. That follows from routing the pulse identity through the same predicate. RetailWorldPicker, RetailSelectionScene, WbDrawDispatcher, and EquippedChildRenderController are untouched, as are all wire and physics paths. The slice REMOVES an undocumented deviation (Attached projections excluded from pick eligibility versus retail's part-id pick) and introduces none, so no retail-divergence-register row is owed in either direction. Gates: dotnet build green; AcDream.App.Tests 3,951 passed / 3 skipped; complete Release solution 9,783 passed / 5 skipped; tools\run-connected-world-lifecycle-gate.ps1 RESULT=PASS.

test(app): put every strict-zero site on the probe (#250)
The first commit converted the four members the issue named and left the other sites alone, reasoning that none had been observed failing. A 20-run complete-solution baseline disproved that within minutes: run 2 LiveEntityRuntimeTests.AnimationView_HotSpatialTraversal… run 14 StaticRenderProjectionJournalTests.ActiveAnimatedSynchronization… run 18 StaticRenderProjectionJournalTests.ActiveAnimatedSynchronization… run 19 CurrentRenderSceneOracleTests.SurfaceOverrideFingerprint… Both new names are the same shape as the four — one warm call, then a thousand-iteration loop inside the measured window — and neither had been recorded anywhere. "Not observed failing" only ever meant "not yet observed", and leaving known-shape sites in place would have guaranteed the acceptance gate failed. Run 19 is the sharper lesson: the issue named `SurfaceOverrideFingerprint_DictionaryHotPathAllocatesNothing`, and the first commit converted a *different* test in that same file, so the actually-named member was still on the old shape. Matching by file was not matching by test. Every strict-zero site in the assembly is now on the probe — ten tests. Two came out stricter rather than merely steadier: `StaticRenderProjectionJournalTests` was measuring a synchronise whose journal does **not** coalesce. Repeating it grew the journal by 1,000 entries per call — 192,000 by the end of a probe run — so the steady state the test claimed to measure did not exist and the single-call window had been hiding it. Its step is now the whole frame cycle, synchronise *and* drain, which puts `DrainTo` inside the measured window for the first time and asserts the journal ends empty. `RetailInboundEventDispatcherTests` asserted a hard-coded 1,001 callbacks. It now counts its own dispatches and pins the callback count against that, so the assertion still proves the fast path ran the callback every time without being coupled to a loop bound that no longer exists. Left alone deliberately: the four sites asserting a tolerance rather than zero — `CellViewDedupTests` and `PortalProjectionTests`. Their ceilings already absorb this noise and none has flaked; changing a bound in either direction is a separate decision from fixing a measurement. Worth noting that `PortalProjectionTests`' ceiling exists explicitly to tolerate "a tiered-JIT/ArrayPool bookkeeping transition ... to the first measured batch", which is exactly what the probe removes, so it could probably be tightened to zero now — recorded in the issue rather than done here. Solution build 0 warnings / 0 errors; App suite 3,941 passed / 3 skipped. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

test(app): measure the warmed path, not the path being warmed (#250)
The zero-allocation family failed about one full-suite run in three, on unchanged trees, and had been dismissed as inherent noise in `GC.GetAllocatedBytesForCurrentThread` three separate times. It is not noise. Reading the four members side by side, they share one root: **the measured window was never the warmed path.** UiDatFontTests 1 warm call, then a 10,000-iteration loop inline RenderFrameProductTests 8 warm calls, then a 1,000-iteration loop inline OracleTests 1 warm call, 1 measured call ArchRenderSceneTests warms Apply(registrations), measures Apply(updates) Two mechanisms come out of that table. A test method is JIT-compiled at tier 0 like anything else, and a long-running loop in tier-0 code gets replaced mid-flight by on-stack replacement — which compiles on the thread running the loop, so its bookkeeping is charged to the window being measured. That is the first two. And `ArchRenderSceneTests` warmed one arm of a switch and measured the other, so the measured call was the first ever into `ApplyUpdate` and paid that arm's JIT, type loads and static initialisation inside the window; `RenderFrameProductTests` warmed 8 times, below the tier-0 call-counting threshold of 30, so promotion was still pending when measurement began. That also explains the signature nobody could account for. Alone, the process is quiet and the runtime has finished before the assertion arrives. Alongside eight other test assemblies, tier-0 compilation never stops, the call-counting delay is re-armed continually, and the work slides into the window. Clean in isolation, failing under load, on a tree that changed nothing. `ZeroAllocationProbe` invokes the step many times before measuring anything, then measures windows that run the same already-warmed loop over the same already-taken path. Each window is a batch of 32 invocations and it reports the minimum across 4 of them. Both halves are load-bearing: the minimum is what excludes a one-time cost, and the batch is what keeps the assertion as strong as the loops it replaces — minimising over *single* invocations would report zero for a path that allocates every tenth call, which is a real regression made invisible. I had written it that way first and the apparatus test caught it. **The bound is untouched: exactly zero, no tolerance, no retry, no assertion relaxed.** `ZeroAllocationProbeTests` proves the apparatus can still fail — a step allocating every call reads above zero and does throw, a first-invocation cost reads as zero, a cost every tenth call is caught, and the one stated limit (the batch must cover the period) is pinned as a test rather than left as prose. Without those, a later edit could quietly make the whole family unfailable. Twelve further sites in this assembly still use the hand-rolled shape. None has been observed failing, and each needs its own repeatability analysis — several mutate state or consume monotonic sequences — so they are listed in the issue for adoption when next touched rather than converted blind at scale.

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).

feat(render): Campaign V slice V10 — Vulkan becomes the default backend
THIS CUTOVER AWAITS THE USER'S VISUAL SIGN-OFF. It is not complete. Section 7
of the campaign plan names the V10 sign-off as the only required user stop
besides gate failures, and it has not been given. This commit flips the default
and runs the battery so that the sign-off has evidence in front of it.
ROLLBACK, one line: `git revert` of this commit. It restores the GL default,
the pre-V10 escape-hatch polarity and the gate scripts' inherited backend
together; nothing else has to move with it.
An unset, empty or unrecognised ACDREAM_RENDER_BACKEND now yields
RenderBackendKind.Vulkan. Only `gl` or `opengl`, case-insensitive, selects
OpenGL. The polarity of the typo case flipped with the default and on purpose:
before V10 an unrecognised token had to land on GL because Vulkan was dark and a
typo must never silently start a backend that cannot draw; after V10 it has to
land on Vulkan for the same reason read the other way, because GL is the backend
V11 deletes. `opengl` is honoured beside `gl` because an escape hatch exists to
be found.
Three gate scripts follow the flip. run-offline-pixel-gate.ps1 gains -Backend
(default vulkan) and now FORCES all four determinism levers — backend, day
group, world day fraction, sky phase — plus ACDREAM_MSAA_SAMPLES=0, instead of
inheriting any of them. run-repeat-connected-gate.ps1 and
run-connected-world-lifecycle-gate.ps1 CLEAR ACDREAM_RENDER_BACKEND rather than
setting it, so what they exercise is the process default and an ambient override
in a caller's shell cannot make a GL run wear the default's report.
TEST PIN UPDATED, flagged as required: RenderBackend_DefaultsToGl becomes
RenderBackend_DefaultsToVulkan, and RenderBackend_AnythingElseStaysOnGl splits
into RenderBackend_SelectsGlOnlyForTheEscapeHatchTokens and
RenderBackend_AnythingElseStaysOnVulkan. Five cases replace two. No other test
is touched, weakened or deleted.
AD-46's divergence-register row moves from "dormant until the V10 cutover" to
live, in this commit, per the same-commit register rule.
Battery, all on the new default:
complete Release suite 9,222 passed / 5 skipped / 0 failed (9 projects)
+5 against the pre-flip 9,217; the +5 are this
slice's own escape-hatch cases
#250 family, singly 4/4 pass (none failed in the whole-suite run)
repeat connected gate PASS 3/3 on both columns
world-lifecycle route PASS, 0 failures, both sessions graceful at exit 0
validation layer inserted at instance AND device level by the loader,
zero errors and zero warnings, real frame captured
GL escape hatch verified by two offline launches: 4.3.0 Core Profile
Context, bindless present, exit 0
Every connected launch in the battery reached Vulkan with no environment
variable set, which is the flip itself under test rather than an assertion
about it.
THE PIXEL GATE IS NOT MET, AND WAS NOT RELAXED. Vulkan against a GL-era capture
taken at this commit through the escape hatch, MSAA off and both clocks pinned:
1.099e-03 masked / 3.764e-02 whole-frame, against a 0.001 threshold. 97.9% of
the difference is in the treeline band, and the masked residual of 619 px — set
against a same-backend control of 10 px — sits entirely on the silhouettes of
distant alpha-blended scenery. That is AD-46's registered population; section
5.5.19 measured the same quantity at 497 px / 8.8e-04. Below the band the two
backends are photometrically identical: mean luminance differs by 0.01 of 255.
No baseline was regenerated and no mask or tolerance was widened.
Two instrument findings are recorded in section 5.5.23. The offline gate's sky
mask is still load-bearing — this slice tried retiring it on the reasoning that
V7's clock pins had made it obsolete, and the control refuted that: two launches
of the same binary still differ by 1,011 px on GL and 482 px on Vulkan, almost
all of it in the band. The default went back to 280 with the measurement written
into the script's help. And the repeat gate's desktop witness needs an
uncontested primary monitor: a first attempt reported 1/3, and the two failing
grabs turn out to be a web browser and Discord composited over the client rect,
not a blank frame — the client's Vulkan capture rendered in all six runs.
Nothing GL, ImGui or Studio is deleted. That is V11's scope and it is untouched.

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.

test(app): serialize the classes sharing camera/render process globals (#252)
A full Release App run failed once at Issue181WallPressEquilibriumTests
.Diagnostic_WallPressedCamera_EyeWanderAndViewerCellStability. It passed in
isolation and did not recur across five further whole-suite runs, and the diff
under test touched only the world texture-creation stack -- nothing in camera,
visibility or physics. A cross-class parallelism race was the only plausible
mechanism, not a regression.
Ten App test classes share three process-global mutable statics, and xUnit runs
distinct test classes in parallel by default:
- CameraDiagnostics: AlignToSlope, CollideCamera, TranslationStiffness,
RotationStiffness, UseRetailChaseCamera. These are not merely written, they
are written AWAY from their defaults -- RetailChaseCameraTests sets
AlignToSlope and CollideCamera to false, and three classes set
UseRetailChaseCamera to false -- while RetailChaseCamera.Update,
CameraController.Active, CameraFrameController, WorldRenderFrameBuilder and
MouseLookController read them.
- RenderingDiagnostics.ProbeFlapEnabled, written by CornerFloodReplayTests
and Issue181WallPressEquilibriumTests.
- System.Console.Out, redirected by those same two classes to capture probe
output.
Every one of these classes already saved and restored in try/finally. That is
correct within a class and remains necessary, but it was never sufficient. A
finally bounds a mutation in TIME along its own thread; it cannot stop another
class from reading the static inside that window. Worse, two overlapping
save/restore pairs can interleave so the second restore writes back the FIRST
one's temporary value, leaving the global permanently wrong for the rest of the
run. The Console.Out case is the sharpest instance: an interleaved restore can
install a DISPOSED StringWriter as the process-wide Console.Out, which then
throws in unrelated tests. Serializing the sharers is what makes each class's
existing finally sufficient.
The fix is a marker CollectionDefinition applied to the ten sharing classes,
following the WorldEnvironmentControllerCollection precedent. No collection
fixture: several members are [Theory] cases that need different knob values per
case, so a fixture cannot own the save/restore without rewriting every member's
internals, and it would not help the read side at all. Because every member
references the same compile-time const for the collection name, the grouping
cannot silently drift via a typo.
Membership is deliberately narrow. It covers the eight writers plus two classes
that drive production code which READS a knob another member moves off its
default (HouseExitWalkReplayTests and CameraFrameControllerTests both run
RetailChaseCamera.Update and assert on the resulting eye). Classes that merely
construct a CameraController without a retail chase camera are NOT members --
their reads fall through the null branch and are insensitive.
No production code changed; no assertion was weakened, and no retry, sleep or
tolerance was added.
Verification. Base commit

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

precondition, and the both-arms composition assertion). Complete Release suite

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.

contract tests and nine layout tests); complete Release suite 9,184/5. Strict GL

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 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.

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
UniformSkyParams, invisible until a terrain pipeline is created; and the offline
gate's scene takes the retail PView path rather than the flat safety path,
because ClipRoot falls back to Buildings.OutdoorNode, which puts
RetailPViewPassExecutor on the critical path to the first Vulkan Dereth frame and
makes the "terrain only" intermediate no cheaper than the whole arm.

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.
