1. End users cannot submit a startup pin 🐞 Bug ≡ Correctness
The new device endpoint and response fields have no consumer in either Fleet Desktop or the My device frontend, whose existing Create PIN action still opens only the manual Manage BitLocker instructions. Even on a capable host, the page never collects or posts a PIN and Fleet Desktop never reacts to the new notification.
Agent Prompt
## Issue description
The backend exposes the BitLocker PIN relay, but no frontend client uses it, so end users cannot enter or submit a PIN.
## Fix Focus Areas
- frontend/pages/hosts/details/DeviceUserPage/components/DeviceUserBanners/DeviceUserBanners.tsx[191-219]
- frontend/pages/hosts/details/DeviceUserPage/BitLockerPinModal/BitLockerPinModal.tsx[14-59]
- orbit/cmd/desktop/desktop.go[402-419]
- server/service/handler.go[994-997]
## Recommended Fix
Add the new response fields to the frontend types, show a PIN-entry form when `fleetd_can_set_pin` is true, POST it to the device endpoint, and poll/render `pin_request` outcomes. Make Fleet Desktop respond to `needs_bitlocker_pin` by directing the user to that form while retaining the manual instructions for incapable agents.

- The new Windows notification branches are not exercised by the existing desktop-summary tests, and the added integration flow only checks the My device and Orbit endpoints. Add coverage for capable/incapable fleetd, missing enrollment, and BitLocker-status errors so regressions do not silently suppress or mis-send the login toast.

WalkthroughAdds support for non-admin Windows users to submit a BitLocker startup PIN from the My device page. The server validates and encrypts the PIN, stores it for one-time fleetd collection, records the outcome, and clears the ciphertext after collection. Windows MDM state now tracks fleetd capability and pending requests. Device and Fleet Desktop responses expose PIN state and notifications. Tests cover validation, persistence, service behavior, and the complete integration flow. Priority: ➖ Normal Severity of issue fixed: Medium Merge Risk: 🟠 High · up to This change adds end-user BitLocker startup PIN submission, but several correctness and safety gaps remain. Outcome reports are not tied to the specific PIN that was collected, so a late report can mark the wrong PIN as active and leave a user locked out at boot; a missing server private key can destroy a submitted PIN before it is delivered; and the PIN paths are not license-gated. The Windows agent also does not advertise the new capability, so the feature would not activate end to end. These should be resolved before merge. 🚥 Pre-merge checks | ✅ 2 | ❌ 3❌ Failed checks (3 warnings)

bitlocker_pin_request_pending; ensure GetBitLockerPINRequest exposes the

collection/outcome flow to carry a unique request identifier with each collected
PIN, require that identifier in the outcome request, and update the datastore

- Line 173: In SubmitBitLockerPIN, validate that the required private key is
available before calling TakeBitLockerPINRequest; keep the request unconsumed
when the key is missing, then proceed with taking and decrypting it only after
validation succeeds.
- Line 71: Add a shared current-license Premium check to SubmitBitLockerPIN,
BitLockerPINStateForDevice, setBitLockerPINNotification, GetBitLockerPINForHost,
and SetBitLockerPINOutcome, matching the enforcement pattern used by
UpdateMDMDiskEncryption; ensure each device-facing path rejects access when
Premium is unavailable before processing the PIN operation.
In `@server/service/orbit.go`:
- Line 682: Update the notification flow around setBitLockerPINNotification to
use the current pinCapable value from GetOrbitConfig rather than the stale
state.FleetdBitLockerPINCapable value. Refresh the state capability before
invoking the helper, or pass pinCapable directly, so capability changes are
evaluated during the same poll.

Mark expired BitLocker PIN requests as terminal.
TakeBitLockerPINRequest clears only bitlocker_pin_request_pending when an expired request returns sql.ErrNoRows; GetBitLockerPINRequest still exposes the row as status: pending, and CreatedAt is excluded from JSON. The checked-in DeviceUserPage has no timeout or pin_request handling. Update the row to failed with an expiry error, or expose an equivalent terminal signal so the client can allow a retry.

Authorization Bypass
Reachability: External
Exploitability: Moderate
CWE: CWE-862 — Missing Authorization
Enforce the Premium license on every device-facing BitLocker PIN path.
The device-authenticated submission, state, notification, PIN collection, and outcome paths do not check the current license. A pending PIN can therefore remain usable after the license changes. Add one shared Premium check to SubmitBitLockerPIN, BitLockerPINStateForDevice, setBitLockerPINNotification, GetBitLockerPINForHost, and SetBitLockerPINOutcome, consistent with UpdateMDMDiskEncryption.

Check the private key before consuming the request.
TakeBitLockerPINRequest marks the request delivered and clears pin_encrypted in the same transaction. SubmitBitLockerPIN blocks only new submissions when the key is missing. A request queued while the key existed can therefore be consumed after the service runs without that key, causing the PIN to be lost before decryption. Move the private-key check before TakeBitLockerPINRequest.

Correlate each outcome with the collected request.
The outcome payload contains no request identifier. A delayed outcome for PIN A can therefore update a newer request for PIN B.
For example, the agent can collect PIN A, another session can queue PIN B, and then the success report for PIN A can mark PIN B as set and clear its ciphertext. The user can believe PIN B is active although Windows applied PIN A. This mismatch can cause a boot lockout.
Return a request identifier with the collected PIN. Require the outcome endpoint to submit that identifier. Update the datastore row only when both the identifier and delivered status match.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use the live BitLocker PIN capability for this notification.
setBitLockerPINNotification gates on state.FleetdBitLockerPINCapable, but GetOrbitConfig reads state before persisting pinCapable. A pending request can survive a later capability change because QueueBitLockerPINRequest sets the pending flag independently, and capability updates do not remove the request. When capability changes from false to true, the stale false value suppresses the notification for that poll. Update state.FleetdBitLockerPINCapable or pass pinCapable directly to the helper before evaluating the notification.

In `@server/service/orbit.go` at line 682, Update the notification flow around
setBitLockerPINNotification to use the current pinCapable value from
GetOrbitConfig rather than the stale state.FleetdBitLockerPINCapable value.
Refresh the state capability before invoking the helper, or pass pinCapable
directly, so capability changes are evaluated during the same poll.
