const MAX_LIST_LIMIT: i64 = 200;Expand description
Hard cap on ListRunsReq.limit — guards against a malicious or
buggy client passing e.g. i64::MAX and pulling the entire run
history (DoS / memory blow-up). 200 covers any plausible UI page
size with headroom; Phase 2 pagination cursor work will move this
to client-driven slicing. (kimi P1 on PR #755.)
