MSAL runs with navigateToLoginRequestUrl=false and redirectUri=origin, so
after an interactive login the user lands on the bare root and AuthGate routes
them role-based to /dashboard — dropping the deep link they opened (e.g. a
/sessions/[id] link in a new tab, which has no shared sessionStorage token and
must re-auth).
Stash the intended in-app path before login() in ProtectedRoute and restore it
in AuthGate after auth settles. New lib/postLoginReturn.ts persists it in
sessionStorage (survives the same-tab redirect round-trip) and guards against
open redirects (same-origin "/..." paths only). Do NOT flip
navigateToLoginRequestUrl — it is intentional for the www->portal cross-origin
flow.

Deploy-verified on f4d51ea4: the worker-side adaptive-sampling exclusion
(EnableAdaptiveSampling=false + manual Configure<TelemetryConfiguration>
UseAdaptiveSampling(excludedTypes:"Request;Event")) does NOT take effect in the
Functions isolated worker. Live data showed the enriched worker request copy
(Source=WorkerMiddleware) sampled to ~63% while the redundant host request item
(Source="") stayed fully billed — strictly worse (lossy enriched copy, host
duplicate unchanged). host.json "Host.Results": "Error" likewise did not drop
the host request item (emitted by the host process, not governed by that level).
Restores known-good: default worker sampling (enriched copy complete at normal
traffic, burst-capped) + host.json Host.Results back to Information. L1 storage
dependency filter and L2 Function-trace suppression are unaffected and still
verified live. L4 deferred pending a mechanism verified against the isolated-
worker pipeline. H2/H3/O1/O2 from f4d51ea4 verified healthy (0 exceptions).

Telemetry cost (L4): worker-side adaptive sampling now excludes Request;Event
so the enriched RequestTelemetryMiddleware copy is never thinned; host.json
Host.Results=Error drops the duplicate unenriched host request item. One
complete request row per call instead of two (one unsampled+unenriched, one
sampled+enriched).
Ingest hot path (H2/H3): BlockedDeviceService caches negative answers (30s
revalidation, symmetric with positive entries) so healthy devices no longer
pay a BlockedDevices point-read per request; SessionDeletionGuard returns its
already-loaded row and IncrementSessionEventCountAsync returns the post-merge
snapshot, collapsing ~4 Sessions reads/batch to ~2.
Queue-worker correctness (O1/O2): new GetSessionEventsStrictAsync propagates
storage failures on the analyze + vulnerability-correlate paths so a transient
read fault retries/poisons instead of silently deleting the message after
"analyzing" an empty stream. Fail-soft variant kept for UI/metrics surfaces.
Review fixes: parse prefetched Status as string (the actual wire format, was
int -> optimization never fired); session-aware block over a cached negative
entry keeps its session scope instead of widening to whole-device.
2274/2274 backend tests green.

Setting requestTelemetry.Context.Location.Ip never reached the requests
table: App Insights uses the IP only for geo-lookup then masks the stored
client_IP to 0.0.0.0 (verified — every request in the resource shows
0.0.0.0). On top of that, the only IP reaching the isolated worker is an
Azure-infra hop (West Europe / Amsterdam), not the device's real egress IP
(device geo = Falkenstein). A usable device IP would need a non-masked
custom property AND the correct forwarded header (Front-Door-topology
dependent) — not worth it: TenantId + CorrelationId already isolate a
device (they dissolved the IngestTelemetry "multiplication" illusion).
Remove the dead Context.Location.Ip block + now-unused Security using,
replace with a NOTE documenting why client_IP is intentionally absent so it
is not re-added. ClientIpExtractor.GetClientEgressIp stays (still used by
ReportDistressFunction's stored SourceIp, which is not App-Insights-masked).

Makes the requests table actually usable for diagnosing agent traffic and rate
limits, without adding any new telemetry items — only properties on the already-
emitted, sampling-excluded Request telemetry (host.json excludedTypes "Request;
Event"), consistent with StorageDependencyFilterProcessor.
RequestTelemetryMiddleware:
- client_IP: the isolated worker behind Front Door/App Service left it 0.0.0.0.
Set Context.Location.Ip from X-Azure-ClientIP (Front Door's true client egress
IP) else trusted rightmost X-Forwarded-For. Header values are joined via
StringValues.ToString() so the rightmost trusted hop wins (not a spoofable
left entry). Diagnostic only — the rate limiter independently uses the trusted
hop, so a spoofed value here cannot affect throttling.
- TenantId: agent ingest skips PolicyEnforcementMiddleware so reqCtx.TenantId was
empty. Fall back to X-Tenant-Id, but ONLY on an exact allowlist of device
endpoints that actually validate it (agent telemetry/ingest/error/distress,
bootstrap ingest/error) and only when it is a well-formed GUID — a prefix match
would let anonymous/management routes (bootstrap/validate, bootstrap/sessions,
agent/config, …) be tagged with a spoofed tenant.
RateLimitService: 429 warning is now structured ({RequestsInWindow}/{MaxRequests}
/{WindowSeconds}/{RateLimitKeyPrefix}) so it's queryable; privacy-safe (8-char
prefix only — the key may be a cert thumbprint, bootstrap token, or UPN).
ReportDistressFunction: store the real device egress IP in SourceIp (table entry
+ AgentDistressReport event) via new ClientIpExtractor.GetClientEgressIp; the
rate-limit key keeps the un-spoofable trusted hop.
Full backend suite 2249/2249 green.

The agent never sent X-Correlation-ID, so the backend's CorrelationIdMiddleware
minted a fresh id per inbound request — meaning a single logical upload that
fans out into multiple backend executions could not be tied back together (the
blocker that left the IngestTelemetry request-multiplication question
unanswerable). Wire up the correlation the infra was designed for:
- BackendTelemetryUploader: generate a unique X-Correlation-ID per upload (per
attempt, so a retry is a distinct traceable request) and log `corr=` on every
outcome line (flushing/OK/TRANSIENT/TIMEOUT/NETWORK/PERMANENT).
- BackendApiClient.AddSecurityHeaders: same per-request id for register/config/
diag/error, with a Debug line carrying corr + path.
Payoff: `requests | where name=='IngestTelemetry' | summarize count() by
tostring(customDimensions.CorrelationId)` now gives the per-request
multiplication factor deterministically (1 = clean, N = multiplied).
Test: updated the uploader logging assertion to the new `ingest OK (corr=` +
`items=N` format. Full V2.Core suite 1266/1266 green.

Follow-up to 28885f7b. RequestStop() called UnregisterWait(), nulling
_registeredWait. When a Changed handler calls RequestStop() and then
queues Stop()/Dispose() to another thread while the callback is still
running — exactly the RealmJoinWatcher appearance-handler shape — the
queued Stop() then saw a null _registeredWait, skipped the blocking
Unregister(waitObject), and returned BEFORE the in-flight callback
finished. That defeated the Thread.Join() parity guarantee on the most
important RequestStop path.
RequestStop() now only sets _stopped and Set()s the signal, leaving the
live registration in place so Stop()/Dispose() can wait on it. The Set()
wakes any still-pending wait, which drains as a no-op (proceed is false
once _stopped is set); a callback already in flight is awaited by Stop().
No deadlock: Stop runs on a different thread and never holds _sync during
the wait.
Test: deterministic guard — park the callback inside the handler, call
RequestStop(), then assert Stop() blocks until the handler completes
(release fired 250ms later on another thread). Proven to FAIL when the
UnregisterWait() is reintroduced into RequestStop(). Full V2.Core suite
1266/1266 green.

Two review findings on the ThreadPool-wait RegistryWatcher (993ebbaa):
P1 (correctness, would silently break in production): force
REG_NOTIFY_THREAD_AGNOSTIC into the effective filter regardless of the
caller's argument. Without a dedicated long-lived thread, the first
RegNotifyChangeKeyValue is issued on the transient Start() caller thread
and re-armed on rotating ThreadPool threads; without this flag the kernel
ties the registration to the issuing thread and cancels the notification
once it ends/recycles. AadJoinWatcher / ProvisioningStatusTracker /
RealmJoinWatcher all pass filters WITHOUT the flag — OR'ing it in the
ctor keeps them correct. (Win8+ only; all Autopilot devices are Win10+.)
P2 (semantic parity with the old Thread.Join): Stop() now issues a
blocking Unregister(waitObject) and waits for any in-flight OnSignalled
callback to finish BEFORE disposing _signal / _keyHandle, so Changed can
no longer fire (nor a freed handle be used) after Stop()/Dispose()
returns. The wait runs outside _sync so the callback's re-arm path can
still observe _stopped; it is deadlock-free because Stop() is never
called from within a handler (callers use RequestStop or queue Stop to
another thread). OnSignalled no longer nulls _registeredWait up front so
Stop can wait on the live registration.
Test: deterministic guard asserting the watcher forces ThreadAgnostic
into its effective filter for callers that omit it. A behavioural
thread-death test is unreliable — without the flag the kernel emits a
*spurious* signal on arming-thread death that a Changed-based test cannot
distinguish from a real change. Full V2.Core suite 1265/1265 green.

Reduce the V2 agent footprint during enrollment without touching any
capability or the deliberate live-tracking cadences (DO 3s poll, IME
100ms poll, download_progress ImmediateUpload — all product USP).
RegistryWatcher: replace the dedicated background thread (new Thread +
WaitHandle.WaitAny on RegNotifyChangeKeyValue) with a ThreadPool wait
(ThreadPool.RegisterWaitForSingleObject), mirroring the proven pattern
in Monitoring/Telemetry/Office/RegistryChangeWatcher. Removes up to
~7-8 dedicated ~1MB thread stacks (Enrollments + CloudDomainJoin +
AadJoin + Provisioning + up to 4x RealmJoin). The public contract is
preserved verbatim: ctor signature, Changed/Error events, IsRunning,
Start()/RequestStop()/Stop() (incl. deferred rethrow of the captured
background failure) and Dispose(). Arming stays synchronous in Start();
Changed is raised outside the lock; the watcher re-arms after each
single-shot notification. All four consumers run unchanged.
Disposal hygiene:
- WmiCollector: dispose each ManagementObject per iteration (native
WMI/COM memory) via using (obj).
- AgentSelfMetricsCollector: wrap both Process.GetCurrentProcess() in
using var (handle leak in the 60s metrics loop).
Verified: V2.Core + V2 agent build clean; full V2.Core suite 1264/1264
green, incl. the RegistryWatcher Win32 integration tests (value write,
subtree subkey, repeated successive changes) and the RealmJoin /
AadJoin / Provisioning / TenantId consumer tests.

Adds a tenant-scoped, informational overview of devices that failed enrollment
with HTTP 403 because they were not in the tenant's Autopilot / Corporate
Identifier registry. Mirrors the Hardware Whitelist rejection insights but
aggregates per device (serial number), matching how Autopilot registers
individual devices rather than models. Read-only, no webhook.
Backend
- GetDeviceNotRegisteredFunction: route audit/device-not-registered, MemberRead,
filters distress reports on ErrorType == "DeviceNotRegistered", aggregates by
serial (case-insensitive; empty serial -> single bucket); 14-day horizon is
the existing distress-report retention.
- Register route in EndpointAccessPolicyCatalog (fail-closed).
- 8 unit tests for BuildAggregatedResult.
Frontend
- api.distress.deviceNotRegistered().
- NotRegisteredDevicesInsights component (serial/mfr/model/attempts/first/last
seen, green empty-state, unverified-data notice).
- Wired below AutopilotValidationSection.
DeviceNotRegistered (403) covers both Autopilot and Corporate Identifier
validation; the agent cannot distinguish which failed, so copy is neutral.

UI — Office in Install Progress:
- The office_install_* lifecycle now renders in the existing InstallProgress
card as a first-class install row (live elapsed timer while installing +
final duration). page.tsx feeds office_install_started/completed/failed into
the component; InstallProgress maps them onto the same Installing/Installed/
Failed flow via isStarted/isCompleted/isFailed (Office has no postponed/
skipped; appName "Microsoft 365 Apps").
Fix — completed-before-started (field session a7525e97, Office CSP / Win32
wrapper):
- When Office is already on disk as the C2R worker runs (CSP install / a Win32
package that re-runs C2R), the host's OfficeBinaryWatcher initial scan
completes the lifecycle synchronously. BeginIfIdle armed that watcher (via
ObserveInstallationPath) BEFORE emitting started, so completed was emitted
first. Reorder: emit started, then observe the path — guaranteed started ->
completed ordering. Start is still gated by real evidence (process / registry
Scenario\INSTALL / DO job); only the emit order changed.
- InstallProgress defensive guard: a late started on an already-Installed item
backfills startedAt and recomputes durationMs instead of dropping it, so
out-of-order / network-reordered delivery still yields a correct duration.
V2-only + web. ConfigVersion unchanged. V2.Core 1264/1264, web 452/452, tsc clean.

Rev 4 of the Office detector, from field session 7da7dead (agent 2.0.980):
early DO-CDN start worked, but there was no completion and the progress
events were useless.
Completion (was never firing):
- The DO-"ended" heuristic is structurally unreliable for Office — many
parallel CDN jobs churn, finished ones drop out of the list, so the
aggregate never reaches 100% and the job count never cleanly hits zero.
onOfficeDownloadEnded never fired, so the completion/binary check never ran.
- Replace it with an OfficeBinaryWatcher: once the InstallationPath is known
from the registry, a FileSystemWatcher on {InstallationPath} fires when any
core Office binary (WINWORD/EXCEL/POWERPNT/OUTLOOK.EXE — any-of, products can
be excluded) appears on disk -> TryFinalizeCompletion emits completed. Initial
on-arm scan + bounded retry-arm cover armed-late / dir-not-yet-present. The
whole DO-ended close machinery (host close/settle/probe timer,
collector onOfficeDownloadEnded) is removed.
Progress (was noise):
- Connected-Cache delivery is near-instant and the multi-job aggregate never
yields a clean 0..100 bar (7da7dead showed one/five identical 62% events).
- Drop office_install_progress emission entirely. Only started / completed /
failed now. The valuable Delivery-Optimization data ships ONCE as a doSummary
on the completed event: total bytes + Cache-Server / peer / pure-CDN split
(CDN = BytesFromHttp - BytesFromCacheServer on MCC networks) + download mode,
alongside durationSeconds and versionReached.
Log spam:
- The registry watcher fires on every ClickToRun value churn; 7da7dead logged
~4000 "Office install expected" INFO lines. Now OfficeExpected is only raised
until the lifecycle starts, and NotifyOfficeExpected logs at Debug and only
when the probe window re-opens from closed.
V2-only. ConfigVersion unchanged (29). The office_install_progress constant +
MCP/web catalog entries are left in place (now never emitted; optional prune).
V2.Core 1263/1263 green; V2 runtime builds. The FileSystemWatcher itself is
OS-bound and not unit-tested (consistent with the process/registry watchers).

Rev 3 of the Office detector. Stops anchoring the lifecycle on the late,
transient OfficeC2RClient.exe worker (field sessions 8353e03b / 58d52632:
the 3.4 GB Office-CDN download ran ~10 min BEFORE the worker appeared, which
then lived ~5 s — so we only ever saw the download tail, never completion).
Early detection (no new polling):
- DeliveryOptimizationCollector now classifies Office-CDN jobs UNCONDITIONALLY
(dropped the process-driven _officeActive gate). The download is already
visible in the IME-driven polls long before the worker. An event-driven wake
(NotifyOfficeExpected, fired when the registry shows Scenario\INSTALL) covers
the isolated-Office case via a bounded probe window.
Earliest-signal start, paired:
- office_install_started now fires on the first of {Office-CDN DO job,
Scenario\INSTALL registry, OfficeC2RClient.exe} — idempotent, one lifecycle,
with startedTrigger recorded in the payload.
Real completion (filesystem proof):
- On window close (download ended AND worker gone), the host runs a bounded
completion probe: read Configuration\InstallationPath and, if any core Office
binary (WINWORD/EXCEL/POWERPNT/OUTLOOK.EXE) exists under {InstallationPath}\
root\* (version folder enumerated, not hardcoded), emit office_install_completed.
The integrate phase lays binaries down after the stream ends, so the probe
retries (settle, then <=8x15s). No on-disk proof -> stop silently (never a
false completed/failed). Explicit error code -> failed (unchanged).
Wiring: OfficeInstallDetectorHost arms the RegistryChangeWatcher at Start (not
worker-start) and owns the close/probe schedule + an OfficeExpected event; the
DO host/factory take the whole officeHost and route SubmitDoSample /
NotifyOfficeDownloadEnded / OfficeExpected.
V2-only. ConfigVersion unchanged (29). 29 Office tests; V2.Core 1265/1265 green.
Field-validate next enrollment (startedTrigger=do at download start, completed
with coreBinariesPresent); Scenario\INSTALL pre-download timing is TODO(office-followup).

Field session 58d52632 showed a burst of 5 office_install_progress events
within the same second, all carrying an identical, frozen 62% download —
not real progress.
Root cause: Office progress has two triggers, the 3s DO poll and the subtree
RegNotifyChangeKeyValue push on the ClickToRun key. During an active C2R
operation the worker rewrites the undocumented Scenario\* values many times
per second, firing RegNotify each time. BuildProgressSignature included the
raw ScenarioValues dict, so every churn passed the dedup gate and emitted a
progress event — while the folded DO download-% stayed frozen (the DO poll
had not re-sampled within that 1s window) and the raw scenario values are
never surfaced in the payload. Pure noise.
Fix: key the progress dedup signature only on the observable progress
dimensions we actually surface and that represent real forward movement —
VersionToReport, the active scenario name, and the DO download (bytes /
percent). Progress now paces naturally to the DO sampling cadence; the
registry push still drives error-code discovery (and, later, TasksState
phase detection).
V2-only. 22/22 Office detector tests green.

Field session 8353e03b declared a successful Office install as failed. Root cause
(diag zip + do-status.jsonl + registry):
- OfficeC2RClient.exe is a transient launcher (~2s in the field) that kicks off the
operation; the OfficeClickToRun.exe service installs for minutes after it exits.
Treating worker-exit as completion → false office_install_failed.
- The registry has NO StreamingFinished value (so the completion branch could never
fire and the "abandoned" branch always did), and Scenario\INSTALL persists
post-install (so presence is not an "active" signal).
- Office C2R content comes from f.c2r.ts.cdn.office.net AND officecdn.microsoft.com;
the old DO matcher only checked "officecdn" and would never attribute Office jobs.
Conservative fix (completion/failure detection deferred until a live-install capture
of Scenario\INSTALL\TasksState transitions — the real signal: per-task
TASKSTATE_COMPLETED/_INPROGRESS):
- OnWorkerStopped no longer finalizes — emits no terminal. started + progress only.
- Removed the StreamingFinished-based completed/abandoned logic; only an explicit
numeric error code finalizes as failed.
- phase label is "Installing" (cannot distinguish Streaming/Finalizing without a real
signal).
- DO Office matcher now keys on the stable CDN hosts cdn.office.net +
officecdn.microsoft.com (dropped the version-fragile _16_0_ FileId marker).
V2 suite 1257/1257 green.

The progressive paged event fetch replaced the list with the first 200
rows on every SignalR/30s refresh, then re-grew it page by page. On
sessions with >200 events this shrink-then-grow changed the page height
repeatedly, making the scrollbar/viewport jump while reading and dropping
open "Details" panels.
Make the event list append-only and monotonic via mergeNewEvents: only
genuinely new events (keyed identically to the React row key) are appended
at the bottom; existing rows are never replaced. When a refresh brings
nothing new the same array reference is returned, so React skips the
re-render and scroll position + open details stay put. Native scroll
anchoring then keeps the viewport pinned as new events append below.
Session telemetry is append-only/immutable, so keeping existing rows is
safe. The transient-empty-refresh guard is now subsumed by the merge; the
dead sessionIdRef param (only used by the removed warning) is dropped.
Adds mergeNewEvents unit tests.

ANALYZE-SEC-002 fired Warning (confidence 90) on every normal user-driven
Entra-join enrollment. During ESP, Windows writes AutoAdminLogon=1 +
DefaultUserName + AutoLogonSID + no DefaultPassword for the enrolling user —
the exact fingerprint the sysinternals_autologon_suspected heuristic targeted
(enabled && user && !password). AutoLogon-enabled is registry-indistinguishable
from a Sysinternals/kiosk setup during Autopilot, so the heuristic and SEC-002
could never tell a benign enrollment from a real one.
Declare AutoLogon only when a plaintext password is actually present:
- delete ANALYZE-SEC-002 (broad AutoLogon-active warning)
- remove the non-discriminating sysinternals heuristic from AutoLogonAnalyzer
(computation + finding label + checks.sysinternals_autologon_suspected)
- strip the sysinternals condition+factor from SEC-004 (kiosk allow-list, still
a disabled opt-in template) and refresh its now-stale SEC-002 guidance
- ANALYZE-SEC-003 (plaintext DefaultPassword -> high) is now the sole default-on
AutoLogon grade; the autologon_analysis event still carries all raw facts at Info
Tests: assert SEC-002 absent + no rule references the sysinternals signal; add
analyzer regression guard for enabled+user+no-password. V2-only, no ConfigVersion
bump. Build 0 err, AutoLogon 19/19, BuiltInRulesTests 8/8, web tsc clean.

Surfaces the real Microsoft 365 Apps Click-to-Run install lifecycle that the
Intune "integrated" app hides (IME reports done in 1-2 min while C2R keeps
streaming in the background). V2-only.
Event-driven, no idle polling:
- OfficeProcessWatcher: WMI Win32_ProcessStartTrace push on OfficeC2RClient.exe
(+ startup probe) for start; Process.Exited for stop, debounced by a settle
window (OfficeInstallSettleSeconds, default 10s) so short worker gaps in one
install don't trigger a premature office_install_failed.
- RegistryChangeWatcher: RegNotifyChangeKeyValue push on ...\Office\ClickToRun
(Configuration value + Scenario subkey churn); bootstrap fallback watches the
nearest existing ancestor non-recursive + name-only until ClickToRun appears.
- OfficeInstallDetector: pure state machine (Idle->Active->Terminal), emits
office_install_started/progress/completed/failed (progress on real change only,
no heartbeat). Error code only from non-zero numeric/hex Scenario values.
Office Delivery Optimization:
- DeliveryOptimizationCollector extended with a 2nd wake source (Office active),
classifies non-IME Office-CDN jobs and folds aggregated DO bytes/peers/real
download-% into the office_install_* events (not emitted as download_progress
to avoid a phantom app in the backend AppInstallSummary).
Plumbing: office_install_* event-type constants, EnableOfficeInstallDetector +
OfficeInstallSettleSeconds config (ConfigVersion 28->29), MCP + web event-type
catalogs, ANALYZE-OFFICE-001 (office_install_failed -> Warning). 22 detector unit
tests; full V2 suite green.

A telemetry batch containing two rows with the same RowKey made Azure Table
Storage reject the entire entity-group-transaction with HTTP 400 /
InvalidDuplicateRow, surfacing as HTTP 500 on POST IngestTelemetry. Observed
as a 23-minute spike (36x 500) from a single session replaying an overlapping
SessionSignalOrdinal; self-resolved when the agent stopped retrying.
The three V2 ingest write paths (Signals, DecisionTransitions, Index) built
the transaction without deduping duplicate RowKeys and had no fallback (unlike
the Events path). Add a shared TableBatchDedup.ByRowKey helper that collapses
duplicate (PartitionKey, RowKey) entities last-write-wins (idempotent
UpsertReplace) and logs a WARN with the dropped count, so bad agents become
visible in logs instead of failing the batch. SubmitTransaction stays
fail-loud for any other batch error.

Replace the client-side aggregation (drain up to 200k raw sessions over up
to 200 HTTP round-trips, then 7 useMemo passes on the main thread) with a
single call to the new /api/metrics/fleet-health (+ global variant).
- New useFleetHealth hook mirrors useDashboardStats: initial fetch on
scope/range change + 3s-debounced refetch on in-scope SignalR
newSession/newevents + reconnect recovery + stale-race generation guard.
- page.tsx drops the sessions state, the eager-pagination loop
(MAX_EAGER_PAGES/FLEET_PAGE_SIZE) and all aggregation useMemos; it now
renders the server payload. Presentation-only derivations (bar maxima,
axis labels) stay client-side. App-metrics (slowest/failing apps) is
unchanged. Displayed numbers are unchanged (semantics preserved).
- api.ts: metrics.fleetHealth / metrics.globalFleetHealth.
Net effect is runtime/network, not bundle: one small JSON response instead
of a multi-megabyte session drain + main-thread aggregation on large
tenants. Verified: tsc clean, next build green.

Adds a third row to the session detail summary card:
- Reboots: session.rebootCount (V2 only; 0 for V1 / pre-feature sessions)
- Enrollment Type: "Device Preparation" (v2) / "Autopilot" (v1), with a
"(PreProvisioned)" qualifier for White Glove; "Gather Rules" for diagnostic runs
- Join Type: "Hybrid Join" / "Entra Join" from the session's isHybridJoin flag
Status moves to the third row so the grid stays a clean 4-column flow. These
complement (do not duplicate) the DeviceDetailsCard System/Autopilot-Profile
sections. Adds rebootCount to the Session web type.

Fleet Health previously drained up to 200k raw sessions into the browser
(MAX_EAGER_PAGES=200 x 1000) over as many HTTP round-trips, then computed
7 aggregates in useMemo on the main thread. Move that aggregation to the
backend, mirroring the dashboard-stats server-aggregation path.
- MetricsMath.BuildFleetHealthPayload: single pass over the windowed
session list producing stats, daily timeline, top failure reasons, and
model health/slowest/top-failing breakdowns. Semantics ported verbatim
from the client (success rate over ALL sessions; avg duration over
non-in-progress sessions incl. failures), so displayed numbers are
unchanged. Typed FleetHealthMetrics DTO in Shared for a typed contract.
- GET /api/metrics/fleet-health (MemberRead) and
GET /api/global/metrics/fleet-health (GlobalAdminOnly, optional
?tenantId=) reuse the existing ISessionRepository window readers.
- Registered both routes in EndpointAccessPolicyCatalog (fail-closed).
- 9 xUnit tests covering the aggregation semantics.
Frontend swap to these endpoints lands in a follow-up commit. App-metrics
(slowest/failing apps) is already backend-aggregated and untouched.

Review follow-up to the diagnosis waterfall fix. With eager tenant
hydration the session and analysis fetches now run in parallel, but
fetchAnalysisResults alone cleared `loading`. A fast analysis response (or
a slow/failed session fetch) could clear loading while `session` was still
null, briefly flashing a wrong IN PROGRESS / empty state.
Track sessionFetchDone + analysisFetchDone and only end loading once both
have settled (success or failure). Both flags are reset on session
navigation. As a bonus this also clears the spinner on a failed session
fetch in the non-GA path instead of waiting indefinitely.

The diagnosis page fetched the ENTIRE session list (api.sessions.list /
globalSessions.list) just to .find() one session client-side, then gated
the events + analysis fetches on the resolved tenant — a 2-stage waterfall
on the critical render path, plus a large over-fetch.
Switch to the direct single-session endpoint (api.sessions.get); the
backend resolves the tenant via FindSessionTenantIdAsync for global admins
when tenantId is omitted. Eager-hydrate sessionTenantId from TenantContext
so fetchEvents/fetchAnalysisResults fire in parallel with the session
fetch instead of after it. Mirrors the proven pattern in
app/sessions/[sessionId]/hooks/useSessionDetail.ts.

Defer the largest client-only libraries so they no longer ship in the
initial route chunk, and give navigations an instant Suspense fallback.
Code-splitting (measured via `ANALYZE=1 npm run build`, First Load JS):
- /sla: 351 kB -> 249 kB (recharts now dynamic, ssr:false)
- /sessions/[sessionId]/inspector: 269 kB -> 184 kB (@xyflow/react +
dagre lazy-loaded; only the "graph" tab needs them)
- fflate moved to on-demand `await import()` at the zip call sites
(ReportSessionModal, SectionSubmitLogs): -5 kB on /sessions/[sessionId]
and /settings/tenant/[section]
next.config: experimental.optimizePackageImports for recharts,
@xyflow/react, @microsoft/signalr, @azure/msal-react (better tree-shaking).
Perceived performance: add a shared PageSkeleton and route-level
loading.tsx for dashboard, fleet-health, sessions/[sessionId],
diagnosis/[sessionId] and apps/[appName] so App Router streams a skeleton
during navigation instead of a dead frame. Purely additive, no change to
existing client logic.

Wire @next/bundle-analyzer into next.config.ts behind an ANALYZE=1 env
gate so `ANALYZE=1 npm run build` emits client/server/edge treemaps into
.next/analyze/. Measurement infrastructure only -- no runtime behaviour
change. Establishes a baseline before bundle-splitting optimizations.
Baseline First Load JS (next build): shared 103 kB; heaviest routes
/sla 351 kB, /sessions/[sessionId] 316 kB, /dashboard 275 kB,
/sessions/[sessionId]/inspector 269 kB.

Surface "how many reboots did this enrollment have" as a stored,
filterable per-session metric so admins can ask e.g. "machines with
many reboots" via MCP search_sessions.
No agent change: V2 already emits one system_reboot_detected per reboot
(EventLog 6009 boot-time vs session start). The backend counts and stores
it; V1 stays 0 (never emits it).
Hybrid counting:
- Incremental per ingest batch in ClassifyEvents (V2 + legacy V1, shared
EventClassification) -> rebootIncrement on IncrementSessionEventCountAsync,
for a live in-flight value (passed 0 on terminal batches).
- Authoritative reconcile (ReconcileSessionRebootCountAsync): distinct count
of system_reboot_detected from the Events table, idempotent + fail-soft.
Runs centrally in TableSessionRepository.UpdateSessionStatusAsync after any
successful terminal transition (ingest, admin mark, maintenance timeout,
rule-engine fail), and again post-increment in the ingest path to cover
already-terminal batch replays. Self-corrects at-least-once batch double-counts.
Storage/correctness:
- RebootCount preserved across re-registration in StoreSessionAsync (a reboot
IS the restart trigger) and projected in BuildSessionIndexEntity (superset rule).
Search/MCP:
- rebootCountMin/Max pushed to OData in BuildSearchScanFilter (sparse-subset),
decoded in SearchSessionsFunction + QueryRawSessionsFunction, added to the
continuation fingerprint and the fields= projection. Client-side
MatchesRebootCountBounds backstops the device-snapshot + legacy scan paths.
- search_sessions MCP tool gets rebootCountMin/Max + rebootCount projection.
Tests: SessionIndexProjection (superset), StoreSessionReregistrationPreserve,
RebootCountFilterBounds. Suite 2228/2228 green; MCP 220 green.
Inert until backend redeploy; legacy index rows lack the column until next
upsert (excluded by min-filter, intended). Web UI badge deferred.

The apps/list endpoints returned the full per-app list in one shot, so there was
no way to page a large fleet's apps (e.g. for a future MCP consumer).
Backend (apps/list + global/apps/list):
- AppsAnalyticsHelper.BuildAppsListResponse gains opt-in pagination: no pageSize
keeps the legacy full-array body (the web UI pages client-side); pageSize
returns an offset-paginated envelope with count/offset/pageSize/nextLink.
- The list is aggregated in-memory from a deterministic sort, so a plain integer
offset is a stable cursor — no HMAC continuation token needed (unlike the
Azure-Table-backed config/all surface). Added an appName tiebreaker so the sort
is fully deterministic across pages.
- New ParseAppsPaging validates pageSize (1..1000) / skip; both functions 400 on
bad input and build a route-specific nextLink (global echoes tenantId).
Web (Installs tab): client-side pagination (pageSize 20) over the filtered/sorted
apps, matching the Inventory tab — sort/search stay across the full set.
Tests: AppsAnalyticsHelperPagingTests (legacy vs paginated, deterministic order,
last-page nextLink null). Backend 2206/2206, web 446, tsc clean, next build OK.

- DO rollup no longer drops legacy telemetry. MetricsMath.BuildAppMetricsPayload
now delegates to DoAggregator.Compute (the existing single source), which falls
back to peers + http when DoTotalBytesDownloaded is 0 and filters to rows that
actually carry DO telemetry (DoDownloadMode >= 0). Removes the duplicate
summation that used DoTotalBytesDownloaded directly as the denominator.
- InstallsTab DO card now renders whenever any DO source bytes exist (effective
total = max(total, peers+MCC+http)) instead of hiding on totalBytesDownloaded <= 0.
- get_software_inventory: guard the GA inventory path — a Global Admin call with
scope="inventory" and no tenantId now returns actionable guidance instead of a
raw backend 400.
Tests: new MetricsMath fallback test; DO test rows set DoDownloadMode so they pass
the telemetry filter. Backend 2203/2203, MCP 220, web 446, all tsc clean.

/apps becomes a Software hub with three lens tabs synced to ?tab=
(installs | inventory | vulnerabilities) — client-side tabs to avoid a
route collision with the existing /apps/[appName] detail page; drill-down
preserved. Nav label "App Health" -> "Software".
- Installs tab: existing app-health list + a Delivery Optimization card that
renders the deliveryOptimization rollup from /api/metrics/app (peer/MCC
offload %, bytes saved, Peers/MCC/CDN bar).
- Inventory tab: tenant's installed-software inventory (GA picks a tenant via
the scope selector; the inventory endpoint is per-tenant).
- Vulnerabilities tab: tenant-facing CVE/KEV exposure (first time customers
can see their own exposure; was GA-only).
The three lenses key differently (IME app name / Registry identity / CPE-CVE)
so they are merged at the navigation level, not row-joined.
Shared groundwork (de-dupes existing copies):
- lib/formatting.ts (canonical formatBytes/Duration/Throughput/Percent),
lib/vulnerabilitySeverity.ts (severity chips + KEV).
- components/DoBreakdownBar.tsx — DownloadProgress refactored onto it
(behaviour-preserving via the total override).
- components/VulnerabilityExposurePanel.tsx — the GA VulnerabilityDataSection
refactored onto it (removes the inline exposure JSX + local severity map).
- api.ts: metrics.vulnerability, metrics.softwareInventory,
vulnerability.softwareInventory.
Verified: tsc clean, 446 web tests, next build OK.

Backend:
- Extract MetricsMath.BuildAppMetricsPayload as the single source for the
app-metrics aggregation (was duplicated verbatim across the tenant and
global functions) and add a Delivery Optimization rollup: per-app peer/MCC
offload bytes + overall deliveryOptimization summary (peers and MCC counted
separately, peerOffloadPercent credits both as not-from-CDN).
- New tenant-scoped GetTenantSoftwareInventoryFunction (GET metrics/software-
inventory, MemberRead, JWT tenant) + fail-closed policy-catalog entry.
MCP server:
- get_app_install_metrics: role-aware routing (global/metrics/app vs
metrics/app), surfaces the DO rollup.
- get_software_inventory: one role-aware tool; non-GA sees only its own tenant
(no tenantId/scope in schema), GA additionally gets tenantId + scope=unmatched.
New exported paginateInventory client-side pager.
Tests: MetricsMathAppPayloadTests (DO rollup/offload/sample-floor) + vitest
paginateInventory. Backend 2202/2202, MCP 220 passed, tsc clean.

Reworks PPKG detection to one aggregate event the rules parse as an array,
adds a default + customizable allow-list, and makes the event storage-safe.
Rule engine:
- New condition source event_data_array + ItemField: iterates an array field
(any-element match), with dot-path dataField support. (RuleEngine.ConditionEvaluators)
Agent:
- Drop per-package provisioning_package_detected events (noise: a clean Win11 VM
ships ~22 OS-inbox .ppkg). One provisioning_package_scan carries an artifacts[]
array; anyPpkgFound derived from it (consistent, incl. recovery residue).
- Size-based chunking: split artifacts across multiple scan events so each event's
Newtonsoft DataJson stays < 24k (well under the 30k Table-Storage truncation that
would blind the rule); never drops a tail artifact. Per-artifact string fields
(identity/dir/rank/installTime) hard-capped at 256; scanErrors capped.
Rules:
- ANALYZE-SEC-005 (default on) + SEC-006 (template) fire on artifacts.identity
not matching an anchored allow-list (^(?:...)\b) that covers OS-inbox families.
- ANALYZE-SEC-007 alarms when a per-source collection cap was hit (scanTruncated).
Web/MCP/docs: event_data_array in the rule form (types + fields), analyze-rules
docs section + example, event-type catalogs.
Tests: rule-engine array/anchor/dot-path/SEC-007; agent artifacts/chunking/field-cap
/worst-case-size. Build green; V2.Core 1236; backend rule + web tsc green.

V2-only AutoLogonAnalyzer that reads the Winlogon AutoLogon configuration and
emits an autologon_analysis event with raw facts at Info severity. AutoLogon can
be a legitimate kiosk/shared-device setup or a way to automate enrollment/OOBE;
the agent reports facts only and never reads the DefaultPassword value (presence
detected via value-name enumeration). Backend analyze-rules grade the facts.
- AutoLogonAnalyzer (always-on, no tenant toggle): startup no-op, runs at
DeviceSetup-phase completion (new AutoLogonDeviceSetupTrigger on
EspAndHelloHost.DeviceSetupProvisioningComplete) and at final shutdown.
- Sysinternals Autologon heuristic (AutoLogon enabled + default user + no
registry password = LSA-secret credential); never reads the LSA secret.
- Analyze rules: ANALYZE-SEC-002 (AutoLogon enabled -> warning, default-on),
ANALYZE-SEC-003 (plaintext DefaultPassword -> high), ANALYZE-SEC-004 (kiosk
allow-list template). Sysinternals graded via a real confidence condition
inside SEC-002/004 so the allow-list still suppresses approved kiosks.
- autologon_analysis added to all event-type catalogs; rule-builder picker also
gains the previously-missing integrity_bypass_analysis + local_admin_analysis.

V2 PPKG scanner that runs once at DeviceSetup-phase start and reports raw facts
only — .ppkg file presence, Provisioning\Packages registry metadata,
Recovery\Customizations residue, and best-effort per-package content indicators.
PPKGs can come from legitimate bulk enrollment or be a pre/in-enrollment
manipulation vector; intent is judged by backend analyze-rules, not the agent.
- ProvisioningPackageCollector + ProvisioningPackageHost, wired as a kernel host
in DefaultComponentFactory (one-shot at DeviceSetup start, not at agent start).
- Events: provisioning_package_scan (aggregate) + provisioning_package_detected
(one scalar event per artifact so analyze rules can match per package).
- Analyze rules ANALYZE-SEC-005/006 incl. a per-tenant allow-list template.
- Event-type catalogs kept in sync (Constants.EventTypes, MCP resource-catalog,
rule-builder eventTypes).

StoreSessionAsync rewrites the Sessions row with UpsertEntity (Replace mode)
on every agent restart (same session id re-registration). The preserve-list
carried EventCount/CurrentPhase/durationSeconds/geo but had forgotten
PlatformScriptCount and RemediationScriptCount (added later), so Replace
zeroed them on each restart. Combined with the subsequent full index upsert
and the increment-merge only writing a counter when its increment > 0, this
undercounted scripts and drifted Sessions vs. SessionsIndex (e.g. get_session
platformScriptCount=0 while the index-backed list showed 3).
Preserve both counters from the existing row, mirroring the EventCount path.
Add StoreSessionReregistrationPreserveTests covering preservation on
re-registration and zero-default on first registration.
