Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to User-scoped cleanup can delete another user's messages and workflow steps when they share a conversation, causing destructive data loss; the conversation/index failure path also remains unresolved.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
A failed index write leaves an unusable, unrecreatable conversation.
set(..., "NX") commits the conversation record before the index pipeline runs. If the pipeline fails, execChecked throws, but conv:{id} remains. The conversation is then absent from getConversations, queryConversations, and countConversations, and a retry with the same id throws ConversationAlreadyExistsError. No public method can repair or replace the record.
Roll back the record when the index write fails.

const pipeline = this.client.pipeline();

Preserve other users' records in the all-conversations path.
The conversation index identifies the conversation owner. It does not identify every message and step owner. If a conversation owned by user-1 contains user-2 records, clearMessages("user-1") deletes those records at Lines 385-388.
Apply the same per-entry ownership filtering used by the conversationId branch for every indexed conversation.
Proposed fix
const ids = await this.client.zrange(this.key("convs", "user", userId), 0, -1);
- const pipeline = this.client.pipeline();
for (const id of ids) {
- pipeline.del(this.key("msgs", id));
- pipeline.del(this.key("msgdata", id));
- pipeline.del(this.key("steps", id));
- pipeline.del(this.key("stepdata", id));
+ await this.clearMessages(userId, id);
}
-
- await this.execChecked(pipeline);
this.log(`Cleared messages for user ${userId}`);📝 Committable suggestion

This picks up where #1174 left off — that PR was abandoned by its author after your review, so I reimplemented the adapter from scratch following the same overall direction and fixed all the issues the bot reviews raised there:
