Sandbox verification was unavailable.Verify the sampled sub-range path against mid-frame republication.
resolveComputePassResourcesruns once per frame at Line 3107, before the pre-scene compute loop executes.entry.bindingResourceis therefore a snapshot taken before any compute pass publishes a new view. The full-mip branch avoids this by readingresource.publishedView, but the sub-range branch returns the snapshot. A pass that reads a mip sub-range of a texture republished earlier in the same frame then binds the previous physical view.Confirm also that the snapshot honours the requested mip range. The resolver stores
bindingResource: resolved.reference.baseView, and the name suggests a base view rather than a ranged view.

Inline comments:
In `@apps/web/src/lib/content/docs/compute-shaders/index.svx`:
- Line 123: Update the provider sentence in the compute-shader documentation so
“the returned object is snapshot” uses grammatical wording, such as “is
snapshotted” or “is captured,” without changing its meaning.
In `@apps/web/src/routes/playground/demos/data-mosh/shaders/fragment.wgsl`:
- Around line 16-20: Update frag to derive the sourceAspect passed to coverUv
from feedback’s texture dimensions instead of using the hardcoded 16/9 value,
while preserving the existing resolution and sourceUv flow.
In `@apps/web/src/routes/playground/demos/data-mosh/shaders/mosh.wgsl`:
- Around line 54-62: Update the highlight gain expression in the shader’s mosh
color calculation to use the intended small coefficient for activity instead of
the anomalously large value, while preserving the surrounding color and reset
logic.
In `@apps/web/src/routes/playground/demos/liquid-simulation/react/runtime.tsx`:
- Around line 7-11: Move mediumCanvas, smoothPointer, previousPointer,
pointerEnergy, and wasInside in the React runtime to useRef-backed state so
their values persist across renders. Update the useEffect and useFrame callback
to read and write each ref’s current value, preserving the existing frame-update
behavior and canvas initialization.
In
`@apps/web/src/routes/playground/demos/liquid-simulation/shaders/visualize.wgsl`:
- Around line 35-53: Update slopeStrength so it no longer multiplies waveSlope
by 0.0; restore the intended nonzero slope weighting, or remove waveSlope and
its associated 3x3 calculation loop if the slope term is not needed. Keep the
remaining rim-based calculations unchanged.
In `@apps/web/src/routes/playground/demos/particle-icosahedron/react/runtime.tsx`:
- Line 41: Prevent retained density-frame IDs from becoming valid again when the
frame counter wraps. In
apps/web/src/routes/playground/demos/particle-icosahedron/react/runtime.tsx
lines 41-41, clear both density textures before resetting frameId, and apply the
same reset-and-clear behavior in
apps/web/src/routes/playground/demos/particle-icosahedron/svelte/runtime.svelte
lines 41-41; keep normal frame advancement unchanged.
In `@packages/motion-gpu/e2e/harness/scenarios/ComputeScenario.svelte`:
- Around line 345-352: In both the sample-nearest and sample-linear branches of
ComputeScenario, place seedSampleTexturePass before sampledTextureComputePass in
activePasses so the texture is initialized before sampling.
In `@packages/motion-gpu/src/lib/core/compute-resources.ts`:
- Around line 1523-1539: After all resource entries are built, cross-check
filtering sampler entries against sampled-texture entries: if any sampled
texture has a sampleType other than 'float', throw the existing resourceError
with COMPUTE_RESOURCE_INCOMPATIBLE. Keep the existing comparison-sampler and
materialSampleType validation in the sampler resolution flow, and anchor the new
validation to the resource-entry construction logic around
resolveSamplerReferenceForBinding.

Nitpick comments:
In `@packages/motion-gpu/src/lib/core/compute-resources.ts`:
- Around line 1368-1380: Update resolveComputePassResources to avoid re-running
normalizeComputeResourceMap for maps already normalized and frozen by
ComputePass or PingPongComputePass constructors; add a safe frozen-input fast
path or accept the normalized type directly, while preserving validation and
resolved-resource behavior for unnormalized inputs.
In `@packages/motion-gpu/src/lib/core/compute-shader.ts`:
- Around line 61-79: Update extractComputeParamList to locate the entrypoint via
a COMPUTE_ENTRY_CONTRACT match rather than the fn compute name prefix, then
begin the balanced-parenthesis scan at the matched entrypoint so computeHelper
is excluded and newline-separated fn/compute syntax is supported. In
packages/motion-gpu/src/lib/core/compute-shader.ts lines 61-79, apply the lookup
change; in packages/motion-gpu/src/tests/core/compute-shader.test.ts lines
54-69, add coverage for a preceding computeHelper function and for fn newline
compute syntax.
- Around line 156-160: Update the default branch of the compute-shader
resource-kind switch to include resource.kind explicitly in the runtime error
message, while retaining resource satisfies never as a separate compile-time
exhaustiveness check rather than interpolating it.
In `@packages/motion-gpu/src/lib/core/error-report.ts`:
- Around line 169-173: Update classifyErrorCode to return a fallback report
preserving the supplied code when the switch has no title mapping, using the
existing common severity and recoverable values and an appropriate generic
title/hint. Ensure the createMotionGPUError flow at the explicit-code handling
around motiongpuCode retains that fallback instead of discarding the code and
classifying only from the message.
In `@packages/motion-gpu/src/lib/core/renderer.ts`:
- Around line 1259-1264: In the storage validation block, remove the redundant
config.storage check from the inner condition and retain only validation that
config.width and config.height are explicitly positive. Update the error message
to describe the dimension failure accurately while preserving the surrounding
storage-texture validation.
In `@packages/motion-gpu/src/lib/core/resource-registry.ts`:
- Around line 59-67: Update assertUniqueResource, requireTexture, and
requireStorageBuffer to throw createMotionGPUError with stable, distinct
registry-related error codes while preserving their existing failure messages
and lookup behavior.
In `@packages/motion-gpu/src/lib/passes/PingPongComputePass.ts`:
- Around line 67-73: Update the PingPongComputePass constructor’s
resolveComputePingPongResourcePair error path to catch invalid pair
configuration failures and rethrow them via createMotionGPUError with the
PINGPONG_CONFIGURATION_INVALID code, preserving the original error details and
stable classification for direct consumers.
In `@packages/motion-gpu/src/tests/core/compute-bindgroup-cache.test.ts`:
- Around line 50-57: Split the combined test around createComputeBindGroupCache
into two independent cases: one that reuses the same GPUBindGroupLayout while
changing only the topology key, and another that reuses the same topology key
while changing only the layout. Keep the assertion that each change causes a
second device.createBindGroup call.
In `@packages/motion-gpu/src/tests/core/compute-resources-resolver.test.ts`:
- Around line 546-592: Strengthen the ownership test for
resolveComputePassResources by adding destroy spies to the borrowed rawTexture,
rawBuffer, and rawSampler objects, then assert each spy remains uncalled after
resolution. Replace the ineffective destroy-property check while preserving the
existing binding-resource and external-source assertions.
In `@packages/motion-gpu/src/tests/core/renderer.test.ts`:
- Around line 2174-2193: Call renderer.destroy() at the end of each of the three
newly added scheduling and resource tests, including the tests corresponding to
the additional referenced sections, so registry and fallback-pool cleanup runs
and renderer state does not leak between tests.
In `@packages/motion-gpu/src/tests/core/storage-textures.test.ts`:
- Around line 216-242: Add tests for buildComputeResourceBindings covering the
sampled-texture resource kind with its scalar type, plus sampler resources
selecting sampler and sampler_comparison appropriately. Keep the existing
storage-texture, storage-buffer, and empty-resource coverage unchanged, and
assert the generated WGSL declarations and bindings.
In `@packages/motion-gpu/src/tests/public-api.test.ts`:
- Around line 112-114: Update the assertion for acceptComputeResourceMaps to
compare the returned entries with the expected resources using the neighboring
test’s toEqual pattern, rather than checking only the result length.

activity * 100.08 scales the highlight term by up to about 100. Every other coefficient in this shader stays below 3.0. Wherever activity is non-zero, the result saturates to white after the tonemap in fragment.wgsl. The value looks like a typo for 0.08.

List the seed pass before the sampling pass.
sampledTextureComputePass reads sampleInput, and seedSampleTexturePass writes it. Both mode branches list the reader first. If the render graph preserves the declared order, the first executed frame samples an unseeded 2x2 texture, and the nearest-versus-linear assertions in packages/motion-gpu/e2e/specs/compute.spec.ts can read stale contents.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Sampler compatibility is not checked against sampled textures resolved in the same pass.
Line 1531 only compares a filtering sampler against resolved.materialSampleType. External samplers have materialSampleType === undefined, and the check ignores the sampled textures declared in the same resource map. A pass that binds a filtering sampler together with an unfilterable-float sampled texture (for example rgba32float without the float32-filterable feature) resolves without error. createBindGroupLayout then fails with a generic WebGPU validation error instead of a COMPUTE_RESOURCE_INCOMPATIBLE diagnostic.
Add a cross-check after all entries are built: if any entry is a filtering sampler and any sampled-texture entry has sampleType other than 'float', throw resourceError with COMPUTE_RESOURCE_INCOMPATIBLE.
