+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 pnpm exec convex codegen --dry-run --typecheck enable exits 0
+- [x] #2 pnpm exec tsc --noEmit exits 0 or reports only documented unrelated pre-existing issues
+- [x] #3 pnpm test remains green
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Reproduce Convex typecheck/codegen failures
+2. Regenerate Convex API if required
+3. Fix screenshot Blob typing with minimal runtime-neutral change
+4. Re-run Convex typecheck, tsc, pnpm test
+5. Leave task In Progress until Matthias confirms Done
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Verification/results:
+- Reproduced with `pnpm exec convex codegen --dry-run --typecheck enable` outside sandbox after pnpm sandbox DB failure; initial result failed with TS2339 `internal.usageEvents` missing and TS2322 `Uint8Array<ArrayBufferLike>` not assignable to `BlobPart` in convex/auditGenerationAction.ts.
+- Ran `pnpm exec convex codegen` outside sandbox; generated convex/_generated/api.d.ts now includes usageEvents.
+- Applied minimal ownership-scoped Blob typing fix in convex/auditGenerationAction.ts by wrapping screenshotBytes with `new Uint8Array(screenshotBytes)` before Blob storage.
+- `pnpm exec convex codegen --dry-run --typecheck enable` exits 0.
+- `pnpm exec tsc --noEmit` exits 2 only because of unrelated pre-existing v2_elemente/* errors (missing local generated modules/imports and implicit any issues); no TASK-41/convex/auditGenerationAction.ts errors remain. Per user instruction, v2_elemente fixes were not touched.
+- `pnpm test` exits 0: 363 tests passed, 0 failed.

+## Description

+<!-- SECTION:DESCRIPTION:BEGIN -->
+Keep v2_elemente as PRD/reference snippets while ensuring the production TypeScript check is not broken by those exploratory files.

+- [x] #1 pnpm exec tsc --noEmit exits 0
+- [x] #2 pnpm lint remains green

+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Reproduce tsc failures from v2_elemente snippets
+2. Apply minimal production TypeScript scope fix
+3. Re-run tsc, lint, tests, diff check
+4. Leave task In Progress until Matthias confirms Done
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Reproduced pnpm exec tsc --noEmit failure: production tsconfig includes v2_elemente reference snippets via **/*.ts, while eslint already scopes them out as non-runtime material.
+
+Applied minimal scope fix: tsconfig.json now excludes v2_elemente/** from the production TypeScript program, matching the existing ESLint ignore for reference snippets. Verification passed: pnpm exec tsc --noEmit (exit 0), pnpm lint (exit 0 with two existing generated-file warnings), pnpm test (exit 0, 363 tests passed), git diff --check (exit 0). v2_elemente contents were not edited.
