 ### Fixes
 
 - fix(device-pairing): validate callerScopes against resolved token scopes on repair [AI]. (#72925) Thanks @pgondhi987.
+- Active Memory docs: document the `cacheTtlMs` 1000-120000 ms range and 15000 ms default so setup snippets do not lead users past the schema limit. Fixes #65708. (#65737) Thanks @WuKongAI-CMU.
 - fix(agents): canonicalize provider aliases in byProvider tool policy lookup [AI]. (#72917) Thanks @pgondhi987.
 - fix(security): block npm_execpath injection from workspace .env [AI-assisted]. (#73262) Thanks @pgondhi987.
 - Tools/web_fetch: decode response bodies from raw bytes using declared HTTP, XML, or HTML meta charsets before extraction, so Shift_JIS and other legacy-charset pages no longer return mojibake. Fixes #72916. Thanks @amknight.
