Automated backport of #2925 to stable (backport job run).

AI recommendation: This is a self-contained bug fix that broadens the Nitro transform exclusion from only the pre-built workflow bundle directory to all generated Nitro build artifacts, preventing duplicate class registration. The affected files (packages/nitro/src/index.ts and vite.ts) and the exact workflowBuildDir exclusion logic being fixed exist unchanged on stable, and the change comes with a regression test, so it applies cleanly to the stable branch.

Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.8). Please review the conflict resolution carefully before merging.

Verified this backport against the original #2925 (which I reviewed on main earlier today) hunk by hunk, with attention on the AI-resolved conflicts. Approving.

Fidelity:vite.ts and the changeset are byte-identical to the original. The two files that differ are both correct context adaptations, not semantic drift:

  • index.ts: the same workflowBuildDir → whole-buildDir exclusion swap (identical construction, including the trailing-slash discipline), applied against stable's surrounding context, which lacks main's world-target-injection code. I also checked the lint hazard this kind of resolution can create: join from pathe remains used elsewhere in stable's file (manifest handler paths, steps bundle), so no unused import was left behind.
  • index.test.ts: the resolution correctly added the viteWorkflow import that main's test file already had from neighboring tests — stable's smaller test file needed it introduced.

Applicability confirmed: stable does ship the Nitro-in-Vite pipeline (vite.ts exists with the same exclusion logic, and the tanstack-start e2e lanes run on stable), so this fixes a real 4.x exposure rather than backporting dead code.

Verified locally on the branch:@workflow/nitro builds; the regression test passes (does not re-transform generated Nitro build artifacts, exercising both transform hooks with the serde-class crash vector and the sibling-directory negative case); the single biome warning is pre-existing on the stable baseline (identical before/after).

CI: every lane that exercises this change is green — nitro/nuxt/vite/tanstack-start across dev, prod, postgres, and Vercel-prod, plus all four workbench deployments. The 4 failures are the known stable-branch baseline set: Community World Turso (same lane failed on the #2818/#2926 backports), its required-check aggregator, and the chronically flaky hono/sveltekit Vercel-prod lanes — none of which touch the Nitro transform path.

Verified this backport against the original #2925 (which I reviewed on main earlier today) hunk by hunk, with attention on the AI-resolved conflicts. Approving.
Fidelity:vite.ts and the changeset are byte-identical to the original. The two files that differ are both correct context adaptations, not semantic drift:
  • index.ts: the same workflowBuildDir → whole-buildDir exclusion swap (identical construction, including the trailing-slash discipline), applied against stable's surrounding context, which lacks main's world-target-injection code. I also checked the lint hazard this kind of resolution can create: join from pathe remains used elsewhere in stable's file (manifest handler paths, steps bundle), so no unused import was left behind.
  • index.test.ts: the resolution correctly added the viteWorkflow import that main's test file already had from neighboring tests — stable's smaller test file needed it introduced.
Applicability confirmed: stable does ship the Nitro-in-Vite pipeline (vite.ts exists with the same exclusion logic, and the tanstack-start e2e lanes run on stable), so this fixes a real 4.x exposure rather than backporting dead code.
Verified locally on the branch:@workflow/nitro builds; the regression test passes (does not re-transform generated Nitro build artifacts, exercising both transform hooks with the serde-class crash vector and the sibling-directory negative case); the single biome warning is pre-existing on the stable baseline (identical before/after).
CI: every lane that exercises this change is green — nitro/nuxt/vite/tanstack-start across dev, prod, postgres, and Vercel-prod, plus all four workbench deployments. The 4 failures are the known stable-branch baseline set: Community World Turso (same lane failed on the #2818/#2926 backports), its required-check aggregator, and the chronically flaky hono/sveltekit Vercel-prod lanes — none of which touch the Nitro transform path.

Automated backport of #2925 to stable (backport job run).
AI recommendation: This is a self-contained bug fix that broadens the Nitro transform exclusion from only the pre-built workflow bundle directory to all generated Nitro build artifacts, preventing duplicate class registration. The affected files (packages/nitro/src/index.ts and vite.ts) and the exact workflowBuildDir exclusion logic being fixed exist unchanged on stable, and the change comes with a regression test, so it applies cleanly to the stable branch.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.8). Please review the conflict resolution carefully before merging.

Verified this backport against the original #2925 (which I reviewed on main earlier today) hunk by hunk, with attention on the AI-resolved conflicts. Approving.
Fidelity:vite.ts and the changeset are byte-identical to the original. The two files that differ are both correct context adaptations, not semantic drift:
  • index.ts: the same workflowBuildDir → whole-buildDir exclusion swap (identical construction, including the trailing-slash discipline), applied against stable's surrounding context, which lacks main's world-target-injection code. I also checked the lint hazard this kind of resolution can create: join from pathe remains used elsewhere in stable's file (manifest handler paths, steps bundle), so no unused import was left behind.
  • index.test.ts: the resolution correctly added the viteWorkflow import that main's test file already had from neighboring tests — stable's smaller test file needed it introduced.
Applicability confirmed: stable does ship the Nitro-in-Vite pipeline (vite.ts exists with the same exclusion logic, and the tanstack-start e2e lanes run on stable), so this fixes a real 4.x exposure rather than backporting dead code.
Verified locally on the branch:@workflow/nitro builds; the regression test passes (does not re-transform generated Nitro build artifacts, exercising both transform hooks with the serde-class crash vector and the sibling-directory negative case); the single biome warning is pre-existing on the stable baseline (identical before/after).
CI: every lane that exercises this change is green — nitro/nuxt/vite/tanstack-start across dev, prod, postgres, and Vercel-prod, plus all four workbench deployments. The 4 failures are the known stable-branch baseline set: Community World Turso (same lane failed on the #2818/#2926 backports), its required-check aggregator, and the chronically flaky hono/sveltekit Vercel-prod lanes — none of which touch the Nitro transform path.

Automated backport of #2925 to stable (backport job run).
AI recommendation: This is a self-contained bug fix that broadens the Nitro transform exclusion from only the pre-built workflow bundle directory to all generated Nitro build artifacts, preventing duplicate class registration. The affected files (packages/nitro/src/index.ts and vite.ts) and the exact workflowBuildDir exclusion logic being fixed exist unchanged on stable, and the change comes with a regression test, so it applies cleanly to the stable branch.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.8). Please review the conflict resolution carefully before merging.

Verified this backport against the original #2925 (which I reviewed on main earlier today) hunk by hunk, with attention on the AI-resolved conflicts. Approving.
Fidelity:vite.ts and the changeset are byte-identical to the original. The two files that differ are both correct context adaptations, not semantic drift:
  • index.ts: the same workflowBuildDir → whole-buildDir exclusion swap (identical construction, including the trailing-slash discipline), applied against stable's surrounding context, which lacks main's world-target-injection code. I also checked the lint hazard this kind of resolution can create: join from pathe remains used elsewhere in stable's file (manifest handler paths, steps bundle), so no unused import was left behind.
  • index.test.ts: the resolution correctly added the viteWorkflow import that main's test file already had from neighboring tests — stable's smaller test file needed it introduced.
Applicability confirmed: stable does ship the Nitro-in-Vite pipeline (vite.ts exists with the same exclusion logic, and the tanstack-start e2e lanes run on stable), so this fixes a real 4.x exposure rather than backporting dead code.
Verified locally on the branch:@workflow/nitro builds; the regression test passes (does not re-transform generated Nitro build artifacts, exercising both transform hooks with the serde-class crash vector and the sibling-directory negative case); the single biome warning is pre-existing on the stable baseline (identical before/after).
CI: every lane that exercises this change is green — nitro/nuxt/vite/tanstack-start across dev, prod, postgres, and Vercel-prod, plus all four workbench deployments. The 4 failures are the known stable-branch baseline set: Community World Turso (same lane failed on the #2818/#2926 backports), its required-check aggregator, and the chronically flaky hono/sveltekit Vercel-prod lanes — none of which touch the Nitro transform path.

Automated backport of #2925 to stable (backport job run).
AI recommendation: This is a self-contained bug fix that broadens the Nitro transform exclusion from only the pre-built workflow bundle directory to all generated Nitro build artifacts, preventing duplicate class registration. The affected files (packages/nitro/src/index.ts and vite.ts) and the exact workflowBuildDir exclusion logic being fixed exist unchanged on stable, and the change comes with a regression test, so it applies cleanly to the stable branch.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.8). Please review the conflict resolution carefully before merging.

Verified this backport against the original #2925 (which I reviewed on main earlier today) hunk by hunk, with attention on the AI-resolved conflicts. Approving.
Fidelity:vite.ts and the changeset are byte-identical to the original. The two files that differ are both correct context adaptations, not semantic drift:
  • index.ts: the same workflowBuildDir → whole-buildDir exclusion swap (identical construction, including the trailing-slash discipline), applied against stable's surrounding context, which lacks main's world-target-injection code. I also checked the lint hazard this kind of resolution can create: join from pathe remains used elsewhere in stable's file (manifest handler paths, steps bundle), so no unused import was left behind.
  • index.test.ts: the resolution correctly added the viteWorkflow import that main's test file already had from neighboring tests — stable's smaller test file needed it introduced.
Applicability confirmed: stable does ship the Nitro-in-Vite pipeline (vite.ts exists with the same exclusion logic, and the tanstack-start e2e lanes run on stable), so this fixes a real 4.x exposure rather than backporting dead code.
Verified locally on the branch:@workflow/nitro builds; the regression test passes (does not re-transform generated Nitro build artifacts, exercising both transform hooks with the serde-class crash vector and the sibling-directory negative case); the single biome warning is pre-existing on the stable baseline (identical before/after).
CI: every lane that exercises this change is green — nitro/nuxt/vite/tanstack-start across dev, prod, postgres, and Vercel-prod, plus all four workbench deployments. The 4 failures are the known stable-branch baseline set: Community World Turso (same lane failed on the #2818/#2926 backports), its required-check aggregator, and the chronically flaky hono/sveltekit Vercel-prod lanes — none of which touch the Nitro transform path.

Automated backport of #2925 to stable (backport job run).
AI recommendation: This is a self-contained bug fix that broadens the Nitro transform exclusion from only the pre-built workflow bundle directory to all generated Nitro build artifacts, preventing duplicate class registration. The affected files (packages/nitro/src/index.ts and vite.ts) and the exact workflowBuildDir exclusion logic being fixed exist unchanged on stable, and the change comes with a regression test, so it applies cleanly to the stable branch.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.8). Please review the conflict resolution carefully before merging.

The 4 failures are the known stable-branch baseline set: Community World Turso (same lane failed on the #2818/#2926 backports), its required-check aggregator, and the chronically flaky hono/sveltekit Vercel-prod lanes — none of which touch the Nitro transform path.

Automated backport of #2925 to stable (backport job run).
AI recommendation: This is a self-contained bug fix that broadens the Nitro transform exclusion from only the pre-built workflow bundle directory to all generated Nitro build artifacts, preventing duplicate class registration. The affected files (packages/nitro/src/index.ts and vite.ts) and the exact workflowBuildDir exclusion logic being fixed exist unchanged on stable, and the change comes with a regression test, so it applies cleanly to the stable branch.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.8). Please review the conflict resolution carefully before merging.

Verified this backport against the original #2925 (which I reviewed on main earlier today) hunk by hunk, with attention on the AI-resolved conflicts. Approving.
Fidelity:vite.ts and the changeset are byte-identical to the original. The two files that differ are both correct context adaptations, not semantic drift:
  • index.ts: the same workflowBuildDir → whole-buildDir exclusion swap (identical construction, including the trailing-slash discipline), applied against stable's surrounding context, which lacks main's world-target-injection code. I also checked the lint hazard this kind of resolution can create: join from pathe remains used elsewhere in stable's file (manifest handler paths, steps bundle), so no unused import was left behind.
  • index.test.ts: the resolution correctly added the viteWorkflow import that main's test file already had from neighboring tests — stable's smaller test file needed it introduced.
Applicability confirmed: stable does ship the Nitro-in-Vite pipeline (vite.ts exists with the same exclusion logic, and the tanstack-start e2e lanes run on stable), so this fixes a real 4.x exposure rather than backporting dead code.
Verified locally on the branch:@workflow/nitro builds; the regression test passes (does not re-transform generated Nitro build artifacts, exercising both transform hooks with the serde-class crash vector and the sibling-directory negative case); the single biome warning is pre-existing on the stable baseline (identical before/after).
CI: every lane that exercises this change is green — nitro/nuxt/vite/tanstack-start across dev, prod, postgres, and Vercel-prod, plus all four workbench deployments. The 4 failures are the known stable-branch baseline set: Community World Turso (same lane failed on the #2818/#2926 backports), its required-check aggregator, and the chronically flaky hono/sveltekit Vercel-prod lanes — none of which touch the Nitro transform path.

Automated backport of #2925 to stable (backport job run).
AI recommendation: This is a self-contained bug fix that broadens the Nitro transform exclusion from only the pre-built workflow bundle directory to all generated Nitro build artifacts, preventing duplicate class registration. The affected files (packages/nitro/src/index.ts and vite.ts) and the exact workflowBuildDir exclusion logic being fixed exist unchanged on stable, and the change comes with a regression test, so it applies cleanly to the stable branch.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.8). Please review the conflict resolution carefully before merging.

Verified this backport against the original #2925 (which I reviewed on main earlier today) hunk by hunk, with attention on the AI-resolved conflicts. Approving.
Fidelity:vite.ts and the changeset are byte-identical to the original. The two files that differ are both correct context adaptations, not semantic drift:
  • index.ts: the same workflowBuildDir → whole-buildDir exclusion swap (identical construction, including the trailing-slash discipline), applied against stable's surrounding context, which lacks main's world-target-injection code. I also checked the lint hazard this kind of resolution can create: join from pathe remains used elsewhere in stable's file (manifest handler paths, steps bundle), so no unused import was left behind.
  • index.test.ts: the resolution correctly added the viteWorkflow import that main's test file already had from neighboring tests — stable's smaller test file needed it introduced.
Applicability confirmed: stable does ship the Nitro-in-Vite pipeline (vite.ts exists with the same exclusion logic, and the tanstack-start e2e lanes run on stable), so this fixes a real 4.x exposure rather than backporting dead code.
Verified locally on the branch:@workflow/nitro builds; the regression test passes (does not re-transform generated Nitro build artifacts, exercising both transform hooks with the serde-class crash vector and the sibling-directory negative case); the single biome warning is pre-existing on the stable baseline (identical before/after).
CI: every lane that exercises this change is green — nitro/nuxt/vite/tanstack-start across dev, prod, postgres, and Vercel-prod, plus all four workbench deployments. The 4 failures are the known stable-branch baseline set: Community World Turso (same lane failed on the #2818/#2926 backports), its required-check aggregator, and the chronically flaky hono/sveltekit Vercel-prod lanes — none of which touch the Nitro transform path.
