Oliver Kieselbach 2e736f40ad feat(backend,shared): Intune Enrollment Validation admits enrolled devices without pre-registration (D-282)
The certificate's Intune managedDevice id is looked up in the tenant's Intune. With the tenant
switch ValidateIntuneDeviceBinding on, that lookup is the last accepting link of the validator
chain: an enrolled device that is not being retired, wiped or deleted is admitted as
ValidatorType.IntuneEnrollment. A 404 for a certificate younger than 60 minutes is
NotFoundRecentEnrollment (503, never cached); a missing grant is 503 with 120 s.

For devices another validator admitted, the lookup only observes: in the background, never
admitting or rejecting, and only when the app token carries
DeviceManagementManagedDevices.Read.All, so a tenant without the add-on costs no Graph call.
Outcomes ride on the request row (CertDeviceBinding, role, serial match, owner and enrollment
type).

TenantConfiguration.HasAnyDeviceValidation() is the single gate precondition; the feature flags
expose it as deviceValidationEnabled (replaces validateAutopilotDevice).

The agent parses ValidatorType strictly: release the agent before this backend.

Oliver Kieselbach c4c253a03a feat(app-homing): name the add-on roles that block the self-service switch and hand the admin the fix
Two tenants clicked the migration banner, consented the new app, and were refused by the
role-superset probe without ever learning why: the previous app's service principal holds a
tenant-side add-on grant (DeviceManagementScripts.Read.All) that no re-consent can produce, and
the grant command on the Optional Graph capabilities page pre-fills the homed (previous) app.

Backend: the probe now separates manifest roles (still propagating after consent ⇒ transient,
the retry converges) from add-on roles (permanent ⇒ MissingRoles names them). consent-status and
access-check carry appHomingPending + appHomingMissingRoles; the manual flip's probe payload
carries missingRoles. The access-check invalidates the Graph caches BEFORE the homing probe so
"Detect existing access" judges a fresh primary token after the admin's grant.

Web: TenantConfigContext learns the blocking roles from either response and the post-consent
poll keeps going while the switch is still converging (previously it stopped on the first
legacy-side reconcile and left the tenant un-switched). Settings → Autopilot Validation shows a
"One more step" banner with the roles, the grant command pre-filled with the NEW app's client id
and -Permissions, and the re-check button; the admin flip error names the roles too.

Oliver Kieselbach ea6a375c4b feat(security): cert-to-device binding, stage 3 GA-gated shadow
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).

Build 0 warnings, backend 4629/4629, web 874/874, tsc clean, eslint 0.

Oliver Kieselbach 1c5f69a9fe w365: CloudPc device validator — cert-CN-bound fallback for Cloud PCs (#127)
* 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.

Oliver Kieselbach 8862d73eed feat(backend+web): detect pre-approved consent for rights-less admins
In larger tenants the multi-tenant app is often pre-approved by someone
with consent rights, while the admin operating our UI lacks them. The
/adminconsent redirect then fails, so ValidateAutopilotDevice/
ValidateCorporateIdentifier never persist and the tenant stays "Disabled"
even though the app + DeviceManagementServiceConfig.Read.All effectively
exist. That bool is also the hard gate in SecurityValidator, so a UI-only
badge would leave agent traffic 403'd.

Add a read-only access-check probe that verifies the concrete role in the
SP token's roles claim (via GraphFeatureDetector, not mere token
acquirability) and, when present, persists the gate bool through the
normal config PUT — opening the UI badge AND the agent gate together.

Backend:
- GraphAppPermissions.DeviceManagementServiceConfigReadAll constant.
- GET /api/config/{tenantId}/autopilot-device-validation/access-check
  (TenantAdminOrGA): InvalidateTenant + fresh GetSnapshotAsync (4s budget),
  pure ResolveAccessPresent (transient => never present), emits
  ConsentAccessDetected telemetry. Always-fresh so a propagation-time
  empty-roles snapshot can't wedge the admin out for the token TTL.

Web:
- lib/accessCheck.ts classifyAccessCheck pure fn (transient/absent never
  reconcile) + tests.
- Reconcile on consent-redirect failure (silently enables) and a per-toggle
  "Detect existing access" button for Autopilot, Corporate, and DevPrep
  Device Association (all share the same role).
- Successful consent callback now verifies the concrete role too: persists
  ONLY on authoritative "reconciled"; transient => retry/propagation
  message, absent => "permission not granted" — neither opens the gate.
- saveConfiguration returns boolean so success is shown only after a
  confirmed persist.

No ConfigVersion bump (backend + web only). Backend 2326/2326, web 464/464.

Oliver Kieselbach e4c4dd57db feat(backend,web): optional Graph add-on permissions for Intune script display names
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.
