 - `sessionRetention`: how long to keep completed isolated cron run sessions before pruning SQLite session rows. Also controls cleanup of archived deleted cron transcripts. Default: `24h`; set `false` to disable.
-- `runLog.maxBytes`: accepted for compatibility with older file-backed cron run logs. Default: `2_000_000` bytes.
-- `runLog.keepLines`: newest SQLite run-history rows retained per job. Default: `2000`.
+- Run history automatically keeps the newest 2000 terminal rows per job. Lost rows retain their 24-hour cleanup window.
 - `webhookToken`: bearer token used for cron webhook POST delivery (`delivery.mode = "webhook"`), if omitted no auth header is sent.
 - `webhook`: deprecated legacy fallback webhook URL (http/https) used by `openclaw doctor --fix` to migrate stored jobs that still have `notify: true`; runtime delivery uses per-job `delivery.mode="webhook"` plus `delivery.to`, or `delivery.completionDestination` when preserving announce delivery.
