P6-7 (CWE-1236): AuditEndpoints CSV export quoted cells on comma/quote/CR/LF
but never neutralized a leading =, +, -, @, TAB, or CR — inbound-API-caller
text landing in Target/ErrorMessage/RequestSummary/ResponseSummary/Extra
could execute as a formula/DDE trigger when opened in Excel. AppendField now
prefixes a literal single quote on free-text columns only (never the
GUID/enum/numeric/date/bool columns the exporter formats itself), applied
before RFC 4180 quoting. The CSV was also missing ExecutionId/
ParentExecutionId/SourceNode that the JSONL export already carried; both are
now 24 columns in the same AuditExportRow order. A second, independently
maintained CSV writer (CentralUI's AuditLogExportService, feeding the Audit
Log page's bulk-export button) had the identical gap and got the identical
fix + column alignment.
P6-8: `audit export` was the one CLI HTTP path with no deadline at all — a
residual gap from the ManagementHttpClient timeout-honesty fix, which made
HttpClient.Timeout infinite and the per-call token the single deadline
everywhere except this streamed GET. RunExportAsync now takes a headers-
received deadline (CancelAfter, reusing ManagementHttpClient.
DefaultConnectTimeout) around the initial GetAsync, an inactivity deadline
around the streaming copy (rearmed on every successful read, so large exports
are bounded by silence, not total size), and an external CancellationToken
wired to Console.CancelKeyPress in AuditCommands so Ctrl-C cancels promptly.
A stalled/faulted stream now produces a friendly error noting the partial
output file instead of hanging or dumping a stack trace.
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.

GetSeriesAsync now branches on window width: windows wider than
RollupThresholdHours (default 168h/7d) read pre-aggregated hourly rollups
via GetHourlySeriesAsync; windows at or below the threshold read raw
samples via GetRawSeriesAsync (preserving intra-minute detail on 24h/7d).
The boundary is strict greater-than, so exactly 168h stays on the raw
path. KpiSeriesBucketer.Bucket runs unchanged on whichever series (a 90d
rollup can still exceed the point ceiling). Both ctors route identically
via a shared FetchSeriesAsync helper reading _options.RollupThresholdHours,
the same options instance that already supplies DefaultMaxSeriesPoints.
GetSeriesAsync public signature unchanged.
