Apple MDM is enabled in NanoHUB mode, but enrollment remains unavailable until the runtime secret contains real Apple-side material. Do not use placeholder values to clear readiness checks.

Secret/fc-devicemgmt-runtime supports these Apple MDM keys:

Key	Purpose
`NANOHUB_API_KEY`	NanoHUB API password for HTTP Basic user `nanohub`.
`APPLE_MDM_APNS_TOPIC`	MDM APNs topic returned after uploading the Apple MDM push certificate to NanoHUB/NanoMDM.
`APPLE_MDM_SCEP_URL`	Live SCEP URL included in the enrollment profile.
`APPLE_MDM_SCEP_CHALLENGE`	SCEP challenge shared with the SCEP provisioner.
`APPLE_MDM_PROFILE_SIGNING_CERTIFICATE_PEM`	PEM certificate used to CMS-sign `.mobileconfig` profiles.
`APPLE_MDM_PROFILE_SIGNING_PRIVATE_KEY_PEM`	PEM private key matching the profile-signing certificate.
`APPLE_MDM_REQUIRE_MANAGED_WIFI_PAYLOAD`	Set to `true` only when Wi-Fi payload delivery should gate enrollment readiness.
`APPLE_MDM_MANAGED_WIFI_SSID`	Managed Wi-Fi SSID for the iPad profile.
`APPLE_MDM_MANAGED_WIFI_PASSWORD`	Managed Wi-Fi password when the network is not open.

Non-secret profile constants stay in GitOps: NanoHUB base URL, MDM server URL, check-in URL, organization/display names, the HTTPS trust anchor certificate, managed Wi-Fi encryption type, auto-join, and MAC-randomization disablement.

Readiness Check

After changing the runtime secret and letting the pod roll, verify:

curl -sk https://devices.iamworkin.lan/api/v1/apple-mdm/enrollment-profile/status

Configurator enrollment must wait until this status reports available=true and an empty missingRequirements array.
