- Key _user_space_cache on _conn_snapshot instead of client object identity, so _new_client() results from the same connection share the cached user (previously every on_memory_write triggered an uncached /api/v1/system/status probe with a 30s default timeout) - Thread a short timeout (0.05s) through the write-path identity probe - Harden _tool_remember to snapshot the client before URI construction + POST, matching the pattern already established in on_memory_write - Remove dead instance method _user_scoped_uri (zero callers; all call sites use the module-level function directly) Co-authored-by: ehz0ah <haozhe4547@gmail.com>
