Important
The new capture.ts file imports tinyest at runtime, but packages/typegpu-testing-utility/package.json does not declare it as a dependency. Running pnpm vitest run --project=!browser packages/typegpu/tests/internal/capturedSnippets.test.ts fails with ERR_MODULE_NOT_FOUND in a clean workspace install (verified locally). Adding tinyest to the testing utility's dependencies resolves the failure.
Reviewed changes — adds a CAPTURE-based snippet extraction utility for more robust TGSL tests, plus the internal exports it needs.
- Add
CapturingGenerator,CAPTURE,captureSnippets, andsimplifyTypeintypegpu-testing-utilityto intercept and collect WGSL snippets during resolution. - Export
dualImplfromtypegpu/~internalso the utility can build a dual-implementation marker function. - Add unit tests in
packages/typegpu/tests/internal/capturedSnippets.test.tscovering regular-resolve no-op behavior, snippet extraction, repeated captures, and inner-to-outer capture ordering.

Reviewed changes since last review — the follow-up commit adds the missing tinyest dependency to packages/typegpu-testing-utility/package.json (and the lockfile) so the new capture.ts module can resolve its runtime import in a clean pnpm workspace.
- Add
tinyestas a runtime dependency oftypegpu-testing-utilityusing theworkspace:*spec.
I verified pnpm vitest run --project=!browser packages/typegpu/tests/internal/capturedSnippets.test.ts now passes and both typegpu-testing-utility and typegpu typecheck cleanly.

Reviewed changes — added a CAPTURE dual-impl helper and captureSnippets utility to the testing package, plus internal exports needed to support them.
- Add
CAPTURE/captureSnippets/simplifyTypetotypegpu-testing-utility—CAPTUREis transparent in normal resolves and records its argument's snippet when resolved throughCapturingGenerator. - Expose
dualImplfromtypegpu/~internal— required to declareCAPTUREas aDualFn. - Add
capturedSnippets.test.ts— covers normal resolution transparency, snippet extraction, re-capture, and nested capture ordering.

The second test needs to be fixed.

So I think we decided that this is intended behavior, and that we want to remove expected type stack, right? I created an issue for that: #2726

Reviewed changes since last review — the new commit cleans up the capture.ts imports and adds a regression test verifying struct-literal capture before return-type casting.
- Consolidate
typegpu/~internalimports incapture.ts— pullsdualImplinto the existingtypegpu/~internalimport rather than importing it separately. - Add
captures structs after castingtest — verifies thatCAPTURErecords the originalBoidstruct data type of{ pos: d.vec3f() }before the function return type casts it.

Reviewed changes since last review — merged latest main into the feature branch and updated the possibleSideEffects snapshot that became stale due to main's new side-effect tracking.
- Synced

Snapshot update aligns the allows snippet extraction test with main's new side-effect tracking for constant abstract expressions.

Gate the four authenticated git-write MCP tools (push_branch, commit_changes, delete_branch, push_tags) on selectedMode ∈ NON_COMMITTING_MODES at invocation time, so Review/IncrementalReview/Plan runs can no longer push or commit code to a branch. Closes the hole that let an IncrementalReview on software-mansion/TypeGPU#2716 push an unprompted snapshot fix. Invariant documented in wiki/modes.md.
