Cause (Documented platform behavior): Empty metadata filters are rejected; SDK 10 validates before sending using the server message.
Fix status: documented_behavior
Misleading approaches:
- Using filter={} as a match-all: only delete has a match-everything mode and it is delete_all=True.
Other error fragments:
- Delete with empty metadata filter is not allowed

Proposed fix: [Pinecone Python SDK 10] delete(filter={}) raises "filter must contain at least one condition, got {}"
Recommended action: Use delete_all=True to delete everything in a namespace; guard dynamic filters so they are omitted when empty.
Option: Use delete_all=True or omit empty filter [evidence: official_recommended_action]
Applies when: delete
Steps:
1. idx.delete(delete_all=True, namespace=...)
Expected: Namespace cleared
