Persistent Memory

Persistent memory is for stable facts that should survive context resets and daemon restarts. It is the layer that gives a familiar continuity.

Good persistent memories

• Familiar identity and role.
• User preferences and communication style.
• Project conventions and hard rules.
• Stable infrastructure notes.
• Repeated lessons from prior incidents.

Poor persistent memories

• Raw command output.
• One-off failed hypotheses.
• Secrets, tokens, or private URLs.
• Temporary task state.
• Facts that are likely to expire quickly.

Promotion rule

Promote memory deliberately. A good persistent memory should still be useful weeks later and should not expose private material in the wrong context.

For concrete sessions and outcomes, use Episodic memory. For concept-based recall, use Semantic memory.
