A dual widevine/playready cdm entry now loads the device of the client's DRM system, for old clients too since they already send cdm_type. A new client hands a capped track to its own device for the track's DRM system, and raises the refusal only after its local vaults miss.
Drop null keys from every licence, server and export source, not only Widevine. dl now finds remote sessions and imports through ServerKeySource instead of private fields.
Cache proxy provider catalogues (10 min), reuse vaults and CDMs across one batch licence call, and cache the health update check, /api/services entries and parsed service config.yaml.
A service option named like a dl option (e.g. --profile) is no longer dropped or mixed with the dl value; the server casts nested values and keeps cli defaults nested.
server_cdm: true on a remote_services entry now licenses remote runs with the server CDM even when the service has its own cdm entry, which stays the local-run device and the fallback. A services.<TAG>.server_cdm replaces the server value for one service, per-service entries match the tag in any case, and the configured fallback logs at info.
BREAKING CHANGE: with server_cdm: true, a per-service cdm entry no longer makes your own device license remote sessions; use dl --cdm or services.<TAG>.server_cdm: false.
A remote client that passes --cdm, has a cdm entry for the service that named the loaded device, or sets server_cdm: false now declines the server CDM at session create, and warns when the server keeps it. A service option listed in SERVER_DEVICE_OPTIONS keeps the server CDM.
Relay the service's CDM calls to the client, accept the service's allowed identity config (for example ESN/Kpe/Kph), add the server_vault grant and a lent server-device mode that reads keys only from vaults and returns no login cache. Also fixes the proxied certificate fetch, Base64 Widevine licences, an answered call that stayed pending and a missing default quality.
A session above the cap licenses with the client's own device, and a track above it in an uncapped -q run is handed back to the client. Also names the fallback in the ccextractor crash warning.
