+# Decision: Superseded sources stay out of answer evidence
+
+- **Status:** decided 2026-10-24
+- **Source:** the owner, in chat
+
+On 24 October 2026 the owner confirmed that the filter merged in PR #3743 stays as it is: a source
+marked outdated (superseded) is removed before any answer route uses it as evidence. This settles
+the apparent conflict with the owner's 21 October rejection of the earlier attempt, PR #3700. The
+rule itself lives in the code comment in `src/lib/rag/superseded-evidence.ts`, find "a superseded
+source is never used as evidence". The 22 October live count found no document marked
+outdated, so nothing changed for users.
