+### `cron`
+
+Cron is a Gateway-owned scheduler for wakeups and scheduled jobs. See `docs/cron.md` for the full RFC and CLI examples.
+
+| Key | Type | Default | Description |
+|-----|------|---------|-------------|
+| `enabled` | boolean | `false` | Enable the cron scheduler inside the Gateway |
+| `store` | string | *(auto)* | Override the cron job store path (defaults to `~/.clawdis/cron/jobs.json` if present, otherwise `~/.clawdis/cron.json`) |
+| `maxConcurrentRuns` | number | `1` | Max concurrent isolated cron runs (command-queue lane `"cron"`) |
+
+Run history:
+- The Gateway appends a JSONL run ledger on each job completion (see `docs/cron.md`). Location is derived from `cron.store` / the resolved store path.
+
+Example:
+
+```json5
+{
+  cron: {
+    enabled: true,
+    maxConcurrentRuns: 2
+  }
+}
+```
