Summary

The memory-core plugin's dreaming feature generates a warning log every time it runs, stating memory-core: narrative session cleanup failed for light/rem phase: missing scope: operator.admin. This occurs because the subagent.deleteSession() method called during narrative session cleanup requires operator.admin permission, but the dreaming cron job runs in the main session which does not have this scope.

Steps to reproduce

Enable memory-core plugin with dreaming feature:

"plugins": {
  "entries": {
    "memory-core": {
      "enabled": true,
      "config": {
        "dreaming": {
          "enabled": true,
          "frequency": "0 */4 * * *"
        }
      }
    }
  }
}
Wait for the dreaming cron to trigger (runs every 4 hours by default)
Check openclaw logs and observe the warning after each dreaming cycle

### Expected behavior

The narrative session cleanup should either:

Succeed without errors when permissions are sufficient, or
Fail silently without a warning log when operator.admin is missing, since cleanup is best-effort and the core dreaming/promotion functionality still works

### Actual behavior

The following warning appears in logs after every dreaming cycle:

Copy
warn plugins {"subsystem":"plugins"} memory-core: narrative session cleanup failed for light phase: missing scope: operator.admin
warn plugins {"subsystem":"plugins"} memory-core: narrative session cleanup failed for rem phase: missing scope: operator.admin
The core dreaming/promotion functionality works correctly, but orphaned narrative subagent sessions may accumulate over time.

### Logs, screenshots, and evidence

```shell
2026-04-17T16:00:56.436+08:00 warn plugins {"subsystem":"plugins"} memory-core: narrative session cleanup failed for light phase: missing scope: operator.admin
2026-04-17T16:01:29.066+08:00 warn plugins {"subsystem":"plugins"} memory-core: narrative session cleanup failed for rem phase: missing scope: operator.admin

Impact and severity

Root cause traced to:

extensions/memory-core/src/dreaming-narrative.ts:933 — calls subagent.deleteSession()
extensions/memory-core/src/dreaming.ts:146 — managed dreaming cron hardcoded with sessionTarget: "main"
Main session lacks operator.admin scope, causing all cleanup attempts to fail
Related code:

Copy
// dreaming.ts:146 — hardcoded sessionTarget
function buildManagedDreamingCronJob(config: ShortTermPromotionDreamingConfig): ManagedCronJobCreate {
return {
sessionTarget: "main", // ← cannot be configured, main session has no operator.admin
wakeMode: "now",
payload: { kind: "systemEvent", text: DREAMING_SYSTEM_EVENT_TEXT },
};
}

// dreaming-narrative.ts:933 — permission-gated operation
try {
await params.subagent.deleteSession({ sessionKey });
} catch (cleanupErr) {
params.logger.warn(
memory-core: narrative session cleanup failed for ${params.data.phase} phase: ${formatErrorMessage(cleanupErr)},
);
}
Suggested fix: When deleteSession() fails due to missing operator.admin, the error should be caught and treated as a non-fatal best-effort cleanup (log at debug level instead of warn), since narrative cleanup failures do not impact the core memory promotion functionality.
