when fw lite always opened on the home page that would trigger a role refresh by loading projects from lexbox. That doesn't happen anymore. We need to refresh on sync, fetching projects from lexbox is cached for 5 minutes, so it shouldn't be too bad on extra network requests.

---

AI summary

FW Lite only updated a project's stored role when the home page loaded the server project list, so a role change on Lexbox didn't reach a project that was already open. This refreshes the role on every successful sync and pushes it to the open project.

Backend

• SyncService looks up the user's role in the server project list after a successful sync. Background syncs use the list cached for 5 minutes, so most make no extra request. A sync started from the sync dialog bypasses the cache, so a role change shows up immediately. If the project isn't in the list (failed fetch, or access removed), the role is left as it is, so a failed fetch can't lock anyone out.
• When the role actually changes, it publishes a new ProjectRoleChangedEvent. The home-page refresh publishes it too.
• MiniLcmJsInvokable.CanWrite reads the role from CrdtMiniLcmApi.ProjectData instead of CrdtProject.Data, which is a snapshot taken when the project was opened and never updated afterwards.
• UpdateUserRole / UpdateProjectServerInfo now return whether the role changed. The ProjectRole ↔ UserProjectRole mappings moved into ProjectRoleMapping.

Viewer

• ProjectContext.watchProjectRole updates projectData.role and refetches features (the write flag) when the event arrives.

Race on project open
Opening a project triggers a sync, which can change the role before the viewer's project context is set up. DotnetProjectView subscribes before calling openCrdtProject:

• A change saved before the backend reads the project data is already in that data.
• A change saved after that read publishes its event after the subscription, so it is always received.

The latest pushed role overrides the snapshot from opening the project, regardless of order.

Note: this adds requests to api/crdt/listProjectsV2, at most one per server every 5 minutes for background syncs, plus one per manual sync.

Test plan

• New UpdateUserRoleTests (LcmCrdt): return value and project-data cache update
• New project-context-role.svelte.test.ts: role event before setup, role event after setup (role and write update), unsubscribe on destroy
• Related LcmCrdt and FwLiteShared tests, svelte-check, eslint, viewer unit tests, i18n drift check
• Manual: open a project as Editor, change your role to Observer on Lexbox, sync from the sync dialog, and check the editor becomes read-only without leaving the project

Walkthrough

Backend services now map project roles, report role changes, and publish project-scoped role-change events. After sync, the service refreshes the local role from the server. The viewer subscribes to these events, overlays the latest role on project data, and refetches features. Write access now uses the live CRDT API’s readonly state. Tests cover role updates, viewer updates, and subscription cleanup.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Suggested reviewers: hahn-kev

Merge Risk: 🔵 Low · up to dfd6c

A role-lookup failure after a completed sync can make the sync look failed or offline and skip follow-up work. After a role change, the viewer can also report contradictory read-only state. Both should be fixed before merge, but the impact is limited.

_{A rabbit watches roles take flight,
The sync brings fresh roles into sight.
Events hop through the viewer’s door,
New features bloom and then refetch once more.
The rabbit twitches, pleased and bright.}

- Line 112: Wrap the RefreshUserRole call in its own try/catch so role lookup
failures do not change the completed sync result or prevent restart and
notification handling. Catch the exception, log it with logger.LogWarning using
the project name, and allow the surrounding sync flow to continue successfully.

Review comments at @frontend/viewer/src/project/project-context.svelte.ts:
- Around line 54-56: Update #projectDataWithLatestRole to recompute isReadonly
from #latestRole when overlaying the role, treating only UserProjectRole.Editor
and UserProjectRole.Manager as writable; import UserProjectRole as a runtime
value rather than type-only. Preserve the existing project data when no latest
role is available.

Looks good. I pushed 49b3b8b so RefreshProjectData also updates CrdtProject.Data; before that the project object's snapshot stayed stale after a sync-path role change.
