+## Maintenance
+
+Cron has two built-in maintenance paths: isolated run-session retention and run-log pruning.
+
+### Defaults
+
+- `cron.sessionRetention`: `24h` (set `false` to disable run-session pruning)
+- `cron.runLog.maxBytes`: `2_000_000` bytes
+- `cron.runLog.keepLines`: `2000`
+
+### How it works
+
+- Isolated runs create session entries (`...:cron:<jobId>:run:<uuid>`) and transcript files.
+- The reaper removes expired run-session entries older than `cron.sessionRetention`.
+- For removed run sessions no longer referenced by the session store, OpenClaw archives transcript files and purges old deleted archives on the same retention window.
+- After each run append, `cron/runs/<jobId>.jsonl` is size-checked:
+  - if file size exceeds `runLog.maxBytes`, it is trimmed to the newest `runLog.keepLines` lines.
+
+### Performance caveat for high volume schedulers
+
+High-frequency cron setups can generate large run-session and run-log footprints. Maintenance is built in, but loose limits can still create avoidable IO and cleanup work.
+
+What to watch:
+
+- long `cron.sessionRetention` windows with many isolated runs
+- high `cron.runLog.keepLines` combined with large `runLog.maxBytes`
+- many noisy recurring jobs writing to the same `cron/runs/<jobId>.jsonl`
+
+What to do:
+
+- keep `cron.sessionRetention` as short as your debugging/audit needs allow
+- keep run logs bounded with moderate `runLog.maxBytes` and `runLog.keepLines`
+- move noisy background jobs to isolated mode with delivery rules that avoid unnecessary chatter
+- review growth periodically with `openclaw cron runs` and adjust retention before logs become large
+
+### Customize examples
+
+Keep run sessions for a week and allow bigger run logs:
+
+```json5
+{
+  cron: {
+    sessionRetention: "7d",
+    runLog: {
+      maxBytes: "10mb",
+      keepLines: 5000,
+    },
+  },
+}
+```
+
+Disable isolated run-session pruning but keep run-log pruning:
+
+```json5
+{
+  cron: {
+    sessionRetention: false,
+    runLog: {
+      maxBytes: "5mb",
+      keepLines: 3000,
+    },
+  },
+}
+```
+
+Tune for high-volume cron usage (example):
+
+```json5
+{
+  cron: {
+    sessionRetention: "12h",
+    runLog: {
+      maxBytes: "3mb",
+      keepLines: 1500,

+## Maintenance
+
+OpenClaw applies session-store maintenance to keep `sessions.json` and transcript artifacts bounded over time.
+
+### Defaults
+
+- `session.maintenance.mode`: `warn`
+- `session.maintenance.pruneAfter`: `30d`
+- `session.maintenance.maxEntries`: `500`
+- `session.maintenance.rotateBytes`: `10mb`
+- `session.maintenance.resetArchiveRetention`: defaults to `pruneAfter` (`30d`)
+- `session.maintenance.maxDiskBytes`: unset (disabled)
+- `session.maintenance.highWaterBytes`: defaults to `80%` of `maxDiskBytes` when budgeting is enabled
+
+### How it works
+
+Maintenance runs during session-store writes, and you can trigger it on demand with `openclaw sessions cleanup`.
+
+- `mode: "warn"`: reports what would be evicted but does not mutate entries/transcripts.
+- `mode: "enforce"`: applies cleanup in this order:
+  1. prune stale entries older than `pruneAfter`
+  2. cap entry count to `maxEntries` (oldest first)
+  3. archive transcript files for removed entries that are no longer referenced
+  4. purge old `*.deleted.<timestamp>` and `*.reset.<timestamp>` archives by retention policy
+  5. rotate `sessions.json` when it exceeds `rotateBytes`
+  6. if `maxDiskBytes` is set, enforce disk budget toward `highWaterBytes` (oldest artifacts first, then oldest sessions)
+
+### Performance caveat for large stores
+
+Large session stores are common in high-volume setups. Maintenance work is write-path work, so very large stores can increase write latency.
+
+What increases cost most:
+
+- very high `session.maintenance.maxEntries` values
+- long `pruneAfter` windows that keep stale entries around
+- many transcript/archive artifacts in `~/.openclaw/agents/<agentId>/sessions/`
+- enabling disk budgets (`maxDiskBytes`) without reasonable pruning/cap limits
+
+What to do:
+
+- use `mode: "enforce"` in production so growth is bounded automatically
+- set both time and count limits (`pruneAfter` + `maxEntries`), not just one
+- set `maxDiskBytes` + `highWaterBytes` for hard upper bounds in large deployments
+- keep `highWaterBytes` meaningfully below `maxDiskBytes` (default is 80%)
+- run `openclaw sessions cleanup --dry-run --json` after config changes to verify projected impact before enforcing
+- for frequent active sessions, pass `--active-key` when running manual cleanup
+
+### Customize examples
+
+Use a conservative enforce policy:
+
+```json5
+{
+  session: {
+    maintenance: {
+      mode: "enforce",
+      pruneAfter: "45d",
+      maxEntries: 800,
+      rotateBytes: "20mb",
+      resetArchiveRetention: "14d",
+    },
+  },
+}
+```
+
+Enable a hard disk budget for the sessions directory:
+
+```json5
+{
+  session: {
+    maintenance: {
+      mode: "enforce",
+      maxDiskBytes: "1gb",
+      highWaterBytes: "800mb",
+    },
+  },
+}
+```
+
+Tune for larger installs (example):
+
+```json5
+{
+  session: {
+    maintenance: {
+      mode: "enforce",
+      pruneAfter: "14d",
+      maxEntries: 2000,
+      rotateBytes: "25mb",
+      maxDiskBytes: "2gb",
+      highWaterBytes: "1.6gb",
+    },
+  },
+}
+```
+
+Preview or force maintenance from CLI:
+
+```bash
+openclaw sessions cleanup --dry-run
+openclaw sessions cleanup --enforce
+```
+

+## Store maintenance and disk controls
+
+Session persistence has automatic maintenance controls (`session.maintenance`) for `sessions.json` and transcript artifacts:
+
+- `mode`: `warn` (default) or `enforce`
+- `pruneAfter`: stale-entry age cutoff (default `30d`)
+- `maxEntries`: cap entries in `sessions.json` (default `500`)
+- `rotateBytes`: rotate `sessions.json` when oversized (default `10mb`)
+- `resetArchiveRetention`: retention for `*.reset.<timestamp>` transcript archives (default: same as `pruneAfter`; `false` disables cleanup)
+- `maxDiskBytes`: optional sessions-directory budget
+- `highWaterBytes`: optional target after cleanup (default `80%` of `maxDiskBytes`)
+
+Enforcement order for disk budget cleanup (`mode: "enforce"`):
+
+1. Remove oldest archived or orphan transcript artifacts first.
+2. If still above the target, evict oldest session entries and their transcript files.
+3. Keep going until usage is at or below `highWaterBytes`.
+
+In `mode: "warn"`, OpenClaw reports potential evictions but does not mutate the store/files.
+
+Run maintenance on demand:
+
+```bash
+openclaw sessions cleanup --dry-run
+openclaw sessions cleanup --enforce
+```
+
+---
+
+## Cron sessions and run logs
+
+Isolated cron runs also create session entries/transcripts, and they have dedicated retention controls:
+
+- `cron.sessionRetention` (default `24h`) prunes old isolated cron run sessions from the session store (`false` disables).
+- `cron.runLog.maxBytes` + `cron.runLog.keepLines` prune `~/.openclaw/cron/runs/<jobId>.jsonl` files (defaults: `2_000_000` bytes and `2000` lines).
+
+---
+
 ## Session keys (`sessionKey`)
 
 A `sessionKey` identifies _which conversation bucket_ you’re in (routing + isolation).
