openclaw - 💡(How to fix) Fix Dreaming short-term promotion promotes cron delivery reports as high-value memories [1 pull requests]

Problem

The Dreaming feature (memory-core short-term promotion) treats cron delivery reports as high-value short-term memories and promotes them into MEMORY.md, polluting durable memory with transient system output.

Impact

• MEMORY.md gets filled with garbage entries like daily news report summaries, code update notifications, and other cron task outputs
• Real user interactions get diluted among system messages
• Users have to manually clean MEMORY.md or disable dreaming entirely

Root cause

The short-term promotion system (memory-core) ingests recent conversation signals including cron task outputs (delivery reports). Since cron tasks run frequently (daily/hourly), their output content accumulates high recall counts and passes the promotion threshold's minRecallCount / minUniqueQueries gates, making them look like "important recurring topics" to the ranking algorithm.

Cron delivery content is structurally different from user conversations — it's one-way system output, not bidirectional interaction worth remembering.

Reproduction

1. Enable dreaming (plugins.entries.memory-core.config.dreaming.enabled: true)
2. Have any cron task that delivers reports via delivery.mode: announce (e.g., daily news, code update checks)
3. Wait for dreaming deep phase to run (~3:30 AM daily)
4. Check MEMORY.md — cron report summaries appear as promoted entries

Expected behavior

Dreaming should filter out or deprioritize content originating from cron deliveries and system announcements — only promote genuine user↔agent interaction signals.

Suggested fix

Add a signal source filter in the dreaming deep phase ranking: deprioritize or exclude content from:

• Cron delivery reports
• System announcements
• One-way broadcast messages without user reply context

Alternatively, add a configuration option to exclude certain session types or message origins from dreaming ingestion.

Environment

• OpenClaw version: v2026.5.7
• Plugin: memory-core with dreaming enabled
• Configuration: default dreaming settings (limit=10, minScore=0.800, minRecallCount=3, minUniqueQueries=3)
