## Summary - migrate the weekly performance regression suite from Mocha to serialized Vitest execution - remove performance-tests ownership of Mocha, `@types/mocha`, Chai 4, and `ts-node` - preserve the weekly report and authentication contracts ### New test helpers These helpers are not required by Vitest. They make behavior that was embedded in the previous Mocha suite explicit and independently testable: - `Cleanup.ts` guarantees that every registered teardown task is attempted, including database closure, report export, `IModelHost` shutdown, and authorization sign-out. If the operation and cleanup both fail, it preserves both errors instead of allowing teardown to hide the primary failure. - `RegressionTestRegistration.ts` constructs the supported test-case/transformer-module combinations synchronously before Vitest registers tests. It skips modules that do not implement the operation required by a test case, preserving the old conditional Mocha registration behavior without asynchronous collection callbacks. - `Cleanup.test.ts` and `RegressionTestRegistration.test.ts` provide focused, non-credentialed coverage for those behaviors. This PR targets `main` and is intended as the new bottom layer beneath the existing quick-performance PRs #353, #354, #356, and #357. It does not modify those branches or their stack metadata. ## Validation - `pnpm --dir packages/transformer build` - `pnpm --dir packages/performance-tests build` - `pnpm --dir packages/performance-tests lint` - `CI=true pnpm --dir packages/performance-tests exec vitest run test/unit/Cleanup.test.ts test/unit/RegressionTestRegistration.test.ts` (4 tests passed) - verified the performance-tests manifest and lockfile importer no longer declare Mocha, `@types/mocha`, Chai 4, or `ts-node` The credentialed Hub-backed weekly runtime suite was intentionally not run locally. Hosted weekly Azure validation remains deferred, consistent with the source migration handoff. *generated with GPT-5.6 Sol* --------- Co-authored-by: Nam Le <50554904+hl662@users.noreply.github.com> Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Co-authored-by: Daniel Rodriguez <DanRod1999@users.noreply.github.com>

The workflow is informational-only and cannot be dispatched until its file reaches the default branch. Calibration intentionally rejects mismatched fixture, workload, execution, package, environment, or hosted-runner image identities; heterogeneous hosted runners may therefore require another calibration dispatch. Only
changeset-scanningis supported in this layer, and the explicitly labeled reduced fixture is smoke-only rather than calibration evidence.generated with GPT-5.6 Sol
