Tenant binding (stage 1) proves the client certificate was issued to this
tenant. It does not prove the certificate belongs to a device the tenant
still has: a cert lifted from a decommissioned machine keeps working.
IntuneDeviceBindingValidator resolves the Intune managedDevice id from the
certificate's Subject CN against the tenant's own managedDevices inventory.
Point-GET on managedDevices/{id} rather than an OData filter, so there is no
filter literal to inject into and a 404 is unambiguous. Cache/retry/transient
contract mirrors CloudPcDeviceValidator.
Shadow only, and visible only to Global Admins (same gate as the DevPrep
association preview) because the open question is a race, not an attack: a
device object can appear after the agent's first call. Every result carries
enrolledDateTime and the log line records enrolledAgeSeconds, so a device
created seconds before the request is distinguishable from a foreign cert.
Grep marker: CERT-DEVICE-BINDING-SHADOW.
The lookup is fire-and-forget like the DevPrep shadow so a cold Graph
round-trip never sits in the agent request path. That rules out stage 1's
request-row dimension (the row is written before the task finishes), hence
the Warning log; widening beyond preview should move to inline + dimension.
Needs DeviceManagementManagedDevices.Read.All, granted per tenant via the
customer script as feature IntuneDeviceBinding. The script's catalog,
ValidateSet and help block stay pinned to GraphFeatureCatalog by
GraphFeatureCatalogSyncTests (extended with the help-block case).

The generated PowerShell command now uses the readable -Features form
(first catalog feature as the example) instead of raw permission strings;
a note below lists all available values incl. the All meta-feature and
how to fall back to -Permissions via Copy permissions. The section links
to the Optional Graph Permissions customer docs (via DOCS_URL registry),
and the "What this script does" bullet reflects the Cloud Shell
ambient-identity sign-in. Script help no longer claims the admin UI
generates the -Permissions form.

All is a script-side convenience that expands to every GraphFeatureCatalog
feature (works with -Revoke too). The catalog sync test now pins All in the
ValidateSet while keeping it out of the catalog comparison, and the admin UI
mentions the shorthand next to the generated grant command.

Try Connect-MgGraph -Identity first (Azure Cloud Shell issues a delegated
token for the signed-in admin, avoiding the device-code flow that
Conditional Access commonly blocks), probe Graph readability, and fall
back to interactive sign-in with explicit scopes otherwise. The
AppRoleAssignment.ReadWrite.All scope guard now applies only to the
interactive path, since ambient-identity tokens carry a fixed scope set.

* w365: CloudPc device validator — cert-CN-bound fallback for Cloud PCs
Windows 365 Cloud PCs are never Autopilot-registered, so the serial lookup
(and the Corporate Identifier fallback) structurally reject them and Cloud PC
first-connect enrollment could not be monitored. New stage-3 fallback in the
device-validation chain: extract the Intune device id from the chain-validated
MDM client certificate's Subject CN (field-verified: CN == managedDevice id ==
cloudPC.managedDeviceId) and require a matching cloudPC object in the claimed
tenant (Graph v1.0 virtualEndpoint/cloudPCs, $filter=managedDeviceId eq).
Only service-provisioned Cloud PCs have such an object — a regular enrolled
non-Autopilot device still ends in the 403, and local W365 markers are never
consulted for auth.
- Shared: ValidatorType.CloudPc = 5, TenantConfiguration.ValidateCloudPcDevice
(default false, tenant-admin writable), GraphAppPermissions.CloudPCReadAll,
GraphFeatureCatalog feature W365CloudPcValidation -> CloudPC.Read.All
- Backend: CloudPcDeviceValidator (AutopilotDeviceValidator sibling contract:
30/5 min cache, 2 attempts, transient->503; GUID gate before the OData
filter; exact-match guard; Graph 403 = definitive "grant missing", not
transient), SecurityValidator CN extraction + fallback stage + hard gate,
wiring through the 5 agent endpoints, TableConfigRepository persistence
- Consent script: W365CloudPcValidation in catalog/ValidateSet/help; NEW
GraphFeatureCatalogSyncTests pins C# catalog <-> grant script (previously
comment-only lock-step)
- Bootstrap dev script v2.3-dev.3: guard 4 (uptime window) exempted while the
Cloud-PC relax is active — Cloud PCs run headless for days before first
connect; the fresh-profile window is the time anchor there (+ Pester tests)
- Web: validation toggle + context plumbing, ValidatedBy "CloudPc" label,
privacy-page validation claim generalized (Last updated bumped)
- Docs: OKF concept doc backend/cloudpc-device-validation.md + index + log
Verified: web tsc clean, ESLint 0 errors (99 pre-existing warnings = ratchet
cap, none added). .NET build/tests and Pester run in CI — SDK download and
pwsh are unavailable in this sandbox's network policy.

* w365: agent-side IsCloudPc flag + engine expectation "no Device-ESP phase"
Companion to the CloudPc validator: the agent now classifies Windows 365
Cloud PCs locally with the bootstrap's field-verified marker AND
(HKLM\SOFTWARE\Microsoft\Windows365 key + installed
CloudManagedDesktopExtension service, probed via its Services registry key
so net48 needs no System.ServiceProcess). SKIP-safe: any error resolves
false. Never an auth input - backend admission stays exclusively the
cert-CN-bound Graph lookup (ValidatedBy=CloudPc); the two signals are
independent and may disagree.
Two transport rails:
- Session metadata: SessionRegistration.IsCloudPc -> Sessions table
(sticky-true OR across re-registrations, IsSelfDeployingProfile pattern)
-> SessionsIndex full mirror -> SessionSummary -> new isCloudPc search
filter end to end (SearchSessions + QueryRawSessions + pagination
fingerprint + all three in-memory predicates; MCP search_sessions /
query_raw_sessions params + summary projection; web type, Cloud PC pill,
SessionInfoCard enrollment label, CSV export appended column).
- Decision engine: isCloudPc rides the EnrollmentFactsObserved payload,
recorded set-once for BOTH values in EnrollmentScenarioObservations.CloudPc
and annotates the scenario profile reason
cloud_pc_first_connect:no_device_esp_expected - the engine-recorded
expectation that Device-ESP already ran headless at provisioning and the
session starts at Account Setup. Deliberately reason+observation only:
no completion arm depends on DeviceSetup, Mode stays AccountSetup/IME-
classified (Classic), EspConfig keeps configured-FirstSync semantics.
Positive marker surfaces as cloud_pc_marker in the audit-trail census.
Updater idempotency: the cloudPcAnnotates gate keeps the generic v1
reason branch from re-claiming the slot on repeat posts (would bump
EvidenceOrdinal every post). Additive-nullable observation - no state
schema bump (v4 convention), serializer roundtrip pinned.
Tests: CloudPcDetector resolver (marker AND, throwing probe), registration
body, facts-signal payload shape, updater annotation/idempotency/
self-deploying interplay, reducer observation both values + census fold,
serializer roundtrip, index projection superset, sticky-true both
directions. Suites: DecisionCore 500, Functions 3941, Agent V2 2154,
vitest 632 - all green; tsc web+MCP clean; ESLint 0 errors (cap 99).
Docs: cloudpc-device-validation.md follow-up section replaced with the
shipped mechanism + log entry.

Adds opt-in resolution of Intune Platform Script + Remediation display names in
session timelines via a tenant-side appRoleAssignment grant. No app manifest
change, no impact on customers who don't enable it. Architecture is reusable for
future optional Graph permissions: catalog -> detector -> resolver -> endpoint.
Backend
- GraphFeatureDetector parses the `roles` claim from the SP access token and
caches the (token, roles) bundle per tenant. GetSnapshotAsync surfaces a
transient flag so admin-UI callers can render "unknown" instead of a
misleading "0 of 0 granted" when token acquire times out.
- GraphTokenService now accepts a CancellationToken so optional-feature callers
can apply tight budgets instead of inheriting the 5+15+30 s retry chain.
- ScriptDisplayNameResolver: cache-first, list-pull-on-cold-tenant, per-ID
fallback. Throttle-aware abort: skip per-ID for kinds whose full-pull hit a
transient failure; break the per-ID loop on the first HttpRequestException.
Total budget 5 s, with a tight 1.5 s sub-budget on the token acquire.
- Azure Table `ScriptNameCache` + direct-TableClient fail-loud repository
(mirrors TableOffboardingAuditRepository pattern). Daily
ScriptNameCacheCleanupFunction: 7 d positive / 1 h NotFound TTL.
- POST /api/tenants/{id}/scripts/display-names (body-carried refs to dodge URL
length limits; backend cap 200 refs/request).
- GET /api/tenants/{id}/graph-permissions/status (4 s budget; includes app
ClientId so the UI can render an exact grant command).
- POST /api/tenants/{id}/graph-permissions/refresh (invalidates token cache).
- All three routes registered in EndpointAccessPolicyCatalog (MemberRead for the
resolve, TenantAdminOrGA for the admin-UI surfaces).
Web
- `useScriptDisplayNames` hook with stable refset fingerprint (no spurious
refetches on parent re-renders); clears stale map on tenant/refset change so
a session switch never leaks names across tenants.
- Chunked POST loop: 200-ref batches with partial-success semantics. Preserves
earlier chunks when later ones fail (non-2xx OR transport throw); only
TokenExpiredError propagates so auth flow can react.
- ScriptExecutions renders " . {DisplayName}" alongside existing label/short-id,
keyed by Kind + policyId so Platform/Remediation under the same id never
collide.
- New Settings section "Optional Graph capabilities": status table with granted
/ not granted / unknown, copy-paste PS one-liner with ClientId baked in,
refresh button gated on response.ok.
Customer-facing
- scripts/CustomerSetup/Grant-AutopilotMonitorAddOn.ps1: idempotent
grant / verify / revoke script. -Features ScriptDisplayNames (high level) or
-Permissions ... (admin-UI generated). Pure ASCII for PS 5.1 compat.
- docs/customer-graph-add-on-permissions.md: end-to-end customer guide
covering prerequisites, the appRoleAssignment pattern, and revocation.
Tests
- 1718 backend xUnit / 364 web vitest. Highlights: JWT roles parsing edge
cases; full-pull-429 suppresses per-ID; per-ID-429 breaks loop; transient
detection via GetSnapshotAsync; chunked partial success (HTTP failure + thrown
transport); TokenExpiredError propagation; EndpointPolicyCatalogCompleteness
covers the three new routes by reflection.
