 # flow-doctor is pulled in transitively via alpha-engine-lib[flow_doctor].
-# [rag] (added in lib v0.3.0) consolidates psycopg2-binary + pgvector + numpy
-# previously listed above as direct deps; kept those direct lines for now to
-# avoid breaking pinning during the migration. Drop the duplicate direct
-# pgvector/psycopg2-binary pins once the migration soaks.
+# psycopg2-binary + pgvector now come via [rag] (added in lib v0.3.0,
+# direct pins dropped 2026-05-20 after >2-week soak on v0.20.0).
