 - New browser-mode specs that need to stub an external library **must not** use `vi.mock(externalLib, factory)`. Add a loader/factory parameter to the underlying hook or service instead.
 - The CI `unit-tests` job includes a permanent grep guard that fails the build if `rpc is closed` appears in any coverage run log. This catches regressions before they reach the acceptance criterion.
 - Acceptance criterion for #535: 60 consecutive green `workflow_dispatch` CI runs against `main` after the fix is merged, with zero `rpc is closed` lines in any log.
+- **Enforcement:** No automated lint rule is planned; the CI coverage guard is the regression backstop. If a lint rule is added later (e.g. an ESLint rule flagging `vi.mock` of non-virtual modules in browser-mode spec files), update this ADR.
+- **When to revisit the LibLoader home:** If three or more components adopt this pattern, consider extracting a shared `$lib/types/lib-loader.ts` or a generic `DynamicImportLoader<T>` type to avoid parallel type definitions across modules.
