+"""add mounts agent_id column, index, and backfill
+
+Mirrors session_id: a bare, nullable varchar populated only for agent mounts
+(session mounts stay agent_id-null), with a partial index for querying "mounts
+for agent X" the same way session_id already supports "mounts for session X".
+
+Backfill: mounts are core DB, so a data migration is allowed here (unlike the
+tracing DB). Agent-mount slugs are minted as
+`__ag__agent__<canonical_artifact_id>__<name>` (`mint_agent_slug`,
+`core/mounts/service.py`) — the artifact id is the raw canonical (lowercase)
+UUID, not a hash, so it is deterministically recoverable straight out of the
+slug. Session-mount slugs (`__ag__session__<uuid5(session_id)>__<name>`) hash
+the session id, so no session_id backfill is possible or attempted here.
