+# Add BM25 without rebuilding the shared Qdrant collection
+
+The workspace keeps its existing unnamed dense vector and adds only the sparse `bm25`
+vector with IDF through Qdrant's additive vector-schema operation. Only Evidence points
+are repopulated with both default dense and BM25 values. Schema, Memory and solved
+questions retain their current dense points and are verified before and after the
+upgrade.
+
+This replaces the planned destructive conversion to a named `dense` vector. If BM25 is
+missing, Evidence preprocessing may add it and verify the resulting schema; session
+runtime remains read-only. An incompatible existing BM25 definition fails without
+mutation. A candidate failure leaves the additive schema in place while Evidence stays
+unavailable, avoiding data loss in the other workflow modules.
