AlarmSummary.razor was gated RequireDeployment but never consulted
SiteScopeService: the site picker listed every site unfiltered and
GetSiteAlarmsAsync ran for whatever siteId the onchange event carried,
so a Deployer scoped to one site could watch any site's live alarms
(including CurrentValue/LimitValue process data). The page was missed
by the ad0100f2 scoping survey.
Fix mirrors EventLogs.razor/DebugView.razor: OnInitializedAsync filters
_sites through SiteScope.FilterSitesAsync, and both the site-change
handler and RefreshAsync (the shared fetch path used by the manual
refresh button and the 15s poll timer) independently re-check the
selected site against the filtered list before ever calling
AlarmSummaryService, denying/resetting an out-of-scope id rather than
merely hiding it from the dropdown.
Tests: bUnit render tests added to AlarmSummaryRenderTests.cs proving
(1) a scoped Deployer's picker omits the out-of-scope site and (2) a
forged out-of-scope onchange value is denied — no row renders and
GetSiteAlarmsAsync is never called for that site. AlarmSummaryVirtualizeTests.cs
updated to register the now-required SiteScopeService.
Wire the operator Alarm Summary page to the transient per-site live alarm
cache (ISiteAlarmLiveCache, T4). Live-cache-first: on site select the page
subscribes and rebuilds rows/rollup from near-real-time onChanged deltas; the
15s poll is kept untouched as the authority for NotReporting and as the
safety net whenever the cache is not live (pre-seed or degraded stream). Both
paths mutate shared state only via the Blazor dispatcher, so they never race,
and each rebuild is an idempotent snapshot.
- IAlarmSummaryService.BuildFromLiveAlarms: flattens a live AlarmStateChanged
snapshot to AlarmSummaryRows with the same deterministic instance-then-name
sort as GetSiteAlarmsAsync; NotReporting always empty on the live path.
- AlarmSummary.razor: inject ISiteAlarmLiveCache; subscribe on select,
re-subscribe on site change, unsubscribe on leave + Dispose.
- Tests: service BuildFromLiveAlarms flatten/sort/empty; page subscribe,
poll-fallback render, onChanged rebuild, unsubscribe on leave/change/dispose.
