Inline comments:
In `@public/app/core/reducers/fn-slice.ts`:
- Around line 73-74: Update nextFnRefreshRevision to filter both current and
requested revisions with Number.isFinite before calling Math.max, treating
non-finite values as the existing zero/fallback while preserving monotonic
behavior for finite negative and fractional revisions.
In `@public/app/features/variables/types.ts`:
- Line 62: Update the dashboardUid field in VariablesTimeRangeProcessDoneEvent
to be readonly, preventing consumers from modifying the dashboard association
after publication.
In `@public/app/fn-app/create-mfe.test.tsx`:
- Around line 42-149: Replace the FNDashboardProps and mfeGetStoreState type
assertions in the refresh tests with typed fixture factories that provide all
required dashboard props and complete FnState entries, including name, mode,
isLoading, setErrors, and refreshRevision. Update the affected update calls and
mockMfeState setup to use these factories, preserving the existing test behavior
while allowing TypeScript to detect contract drift.
In `@public/app/fn-app/create-mfe.ts`:
- Around line 288-290: Update the refresh-update handling around
createMfe.refreshDashboard to reject or return failure when other.uid is missing
or empty before processing refreshRevision. Preserve refresh behavior for valid
UIDs and ensure the lifecycle does not return true when no dashboard was
refreshed.
- Around line 288-290: Update the revision handling around
createMfe.refreshDashboard so a refresh revision is recorded only after
ownership validation and the refresh completes successfully. Ensure a failed
refresh does not advance previousRefreshRevision, allowing the same revision to
be retried.
- Around line 283-290: Serialize dashboard refresh ownership across the full
update lifecycle: ensure a later host update cannot begin while an earlier
refreshDashboard call or its deferred variable-query work is still running.
Update the refresh flow around refreshDashboard and its completion/finally
handling so renderingDashboardUID remains bound to the active dashboard until
all awaited work completes, preventing VariableQueryRunner and
DataSourceWithBackend from resolving a stale shared UID.

Independent CodeRabbit CLI review completed against the final PR diff. CodeRabbit raised 4 issues. After verifying each against the current code, two remain actionable:
I skipped two findings after verification: the refresh helper already receives a UID string, and restoring the shared rendering UID before awaiting is intentional because the request is now bound from The PR is already merged, so the major item should be handled as a follow-up before relying on revision deduplication under overlapping host updates. |
Description
Add an in-place refresh command for embedded dashboards.
The host currently rebuilds the Grafana root when an authorized analytics projection becomes current. Production validation showed that this blanks loaded panels and repeats filter requests. An optional, monotonic per-dashboard
refreshRevisionnow invokes the existing time-range/variable/panel refresh pipeline on the owning dashboard, without replacing its React tree or control portals.Repeated or older revisions are no-ops; initial mount does not issue an extra refresh. Invalid revisions and missing/mismatched dashboard ownership reject the command, and a failed refresh does not consume its revision. Variable requests carry their owning dashboard UID through deferred datasource setup. Variable-completion events also carry that UID so refreshing one dashboard does not refresh another; legacy events without a UID retain their existing behavior.
Deployment
Backward-compatible Grafana-only deployment, US and EU. Existing hosts omit the property and retain their current behavior. Deploy this contract before merging the mono host consumer. No IAM, database, ingestion or tenant-isolation changes. Rollback this fork only before enabling the new host consumer, or revert the host consumer first.
Validation
DashboardModelevent handlers; only the matching UID reachesstartRefresh.request.dashboardUIDfails the variable-runner ownership assertion.References
Agent handoff
User intent: fast tenant-isolated analytics with visible, unobtrusive refresh status and no blanking of usable panels. Keep rollout internal until user review. This PR is the backward-compatible MFE provider contract, not a reader rollout.

Next: verify CI, normal review/merge, then deploy both regions before the mono host consumesrefreshRevision. Do not admin merge without specific user authorization.Redux owner selection lasts only through synchronous thunk binding; deferred variable requests retain ownership through explicit
request.dashboardUID. The previous global owner is restored before awaiting variable completion. Review ownership, async variable completion, repeated revisions and initial-mount behavior. Canned SQL, authorization, scoped credentials and all rollout gates remain unchanged. No customer data or credentials are included in the tests.Summary by CodeRabbit
