MF_E_POLICY_MGR_ACTION_OUTOFBOUNDS
MF_E_POLICY_MGR_ACTION_OUTOFBOUNDS identifies an invalid action value in the policy-management path. Actions are part of the ITA/OTA contract and determine which use of the stream—such as play, copy, or transcode—is being authorized and enforced.
Validate the action at the call boundary
- Log the numeric action value and the API/object that supplied it.
- Check enum conversion, serialization, and versioned IPC boundaries for truncation or stale constants.
- Verify that action values are not being confused with topology node IDs, stream IDs, or application-specific operation codes.
This differs from MF_E_ITA_UNSUPPORTED_ACTION. An unsupported action can still be a recognized action that the ITA does not implement; an out-of-bounds action is invalid for the policy manager's action domain. Retrying policy negotiation cannot make an invalid value valid. Fix the action source or conversion before examining output protection capabilities.
