Models
class ManagedAgentsActor
One of the following:
class ManagedAgentsAPIActor { $type = 'api_actor'; $apiKeyID; }
"api_actor" type
string apiKeyID

ID of the API key (an apikey_... value). This identifies the key, not the secret.

class ManagedAgentsMemoryVersion { $type = 'memory_version'; $id; $createdAt; /* 10 more */ }
enum ManagedAgentsMemoryVersionOperation
One of the following:
"created"

The memory was created. The first version in any memory's lineage.

"modified"

The memory's content, path, or both were changed via update. Writes the agent makes through the filesystem mount also appear as modified.

"deleted"

The memory was deleted. The content, content_size_bytes, and content_sha256 fields are null on this version. The preceding version, while it is retained, records the deleted content's size and hash.

class ManagedAgentsServiceAccountActor { $type = 'service_account_actor'; $serviceAccountID; }
"service_account_actor" type
string serviceAccountID

ID of the service account (a svac_... value).

class ManagedAgentsSessionActor { $type = 'session_actor'; $sessionID; }
"session_actor" type
string sessionID

ID of the session (a sesn_... value). Look up the session via Retrieve a session for further provenance.

class ManagedAgentsUserActor { $type = 'user_actor'; $userID; }
"user_actor" type
string userID

ID of the user (a user_... value).
