+- **chore(quality):** fix two release-tip base-reds blocking every fresh PR run: rename `providerTierField.ts` → `providerTierFieldApi.ts` (case-only filename collision with `ProviderTierField.tsx` from #7838 — breaks webpack on case-insensitive filesystems, caught by the #6584 guard) and register `combo-skip-conn-disable-plugin-block-7806.test.ts` (from merged #7806) in stryker `tap.testFiles`.
