Merged
Conversation
Add metadata parameter to create_event, create_blob_event, fork_conversation, and event_metadata filter to list_events in MemoryClient. - create_event: Added optional metadata parameter for attaching key-value metadata - create_blob_event: Added optional metadata parameter - list_events: Added event_metadata filter for querying events by metadata - fork_conversation: Added optional metadata parameter (passes through to create_event) Metadata supports up to 15 key-value pairs with keys 1-128 characters. Filtering supports EQUALS_TO, EXISTS, and NOT_EXISTS operators.

There was a problem hiding this comment.
nit: The EventMetadataFilter TypedDict in filters.py defines operator: OperatorType (enum), but the docstring examples correctly show passing the string "EQUALS_TO" directly, which is what boto3 actually needs.
This works fine at runtime since Python doesn't enforce TypedDict, and the examples are correct. The root issue is in filters.py where operator should probably be typed as str rather than OperatorType. Worth a follow-up cleanup but def not a blocker for this PR. Should I create an issue for this? Or can we have strands do it?
