+## Final ACTIVE search review fixes
+
+- `ActiveEvidenceSearcher` now treats default (`kinds=None`) and mixed-kind searches as explicit
+  split queries: non-Evidence kinds are queried separately, while Evidence is queried only with
+  ACTIVE manifest generation/document predicates applied server-side before every limit.
+- Results are merged deterministically by descending similarity then stable id and truncated once
+  to the caller's global `top_n`. Pure non-Evidence searches retain their original delegate path.
+- The corpus writer lock now covers manifest snapshot construction and all corresponding vector
+  queries, preventing retain-1 publication/GC from switching or deleting generations mid-search.
+- Removed the public post-LIMIT `active_evidence_hits` helper; no public Evidence path performs
+  client filtering after limit.
+
+Focused default/mixed/no-ACTIVE/search-pack tests pass, the real Docker pgvector lifecycle passes,
+and the final full harness plus scoped Ruff/diff invocation completed with exit code 0.
