Me: Why this:

> I'm adding a lookup to persistEphemeralVFolder so that a repeated search reuses the user's root vFolder with the same query instead of hitting the unique index.

Claude Opus 5.5: A search stores its query as an ephemeral root vFolder. The new unique index on (user, parent query, query) now rejects a second root vFolder with the same query. As written, persistEphemeralVFolder always inserts, so repeating a search would fail its insert, the retry with a fresh short code would fail too, and the search would return an error. The Ephemeral VFolder paragraph we rewrote in the SPECS also says a search reuses the existing vFolder with its query, so the user gets the same short code back.

The lookup I proposed would also copy the query-then-create logic already in the PUT /vfolders handler. A cleaner option is one shared engine function that finds or creates a vFolder by query, called by both the handler and persistEphemeralVFolder. Shall I do that, or keep the local lookup?

Me: I mean, is it not cleaner to fix this: "persistEphemeralVFolder always insert"

And generally, we want the db and its indexes to do their work, not duplicating that in application code with pre-lookups and stuff

Claude Opus 5.5: You're right. Both persistEphemeralVFolder and the lookup I put in the PUT /vfolders handler should be replaced by a save with conflict keys (user, parent query, query), so the unique index decides whether a row is created or updated.
