Document dynamic groups gotcha: silent data loss on PUT#3
Merged
Conversation
Dynamic (smart) groups with isDynamic: true have their membership computed from ruleSets. The API silently accepts PUT requests that include dynamic groups and returns them in the response, but the changes never persist. Discovered after 611 member updates appeared successful but had no effect. Also documents that group color field cannot be empty (422). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
