- Remediation
- <![CDATA[ ## Remediation Suggestions - Do not automatically modify `SOUL.md`, `HEARTBEAT.md`, system prompts, identity documents, or persistent memory. - Return proposed additions to the user as text and require explicit human review and approval before writing them. - Keep network membership state in a narrowly scoped data file that is not interpreted as Agent instructions. - Do not label recurring jobs as mandatory or use expulsion pressure to override human control. - Require separate, explicit consent before creating any scheduled or recurring operation. - Provide a clear uninstall operation that removes all inserted content and disables recurring network activity. - Treat thread messages, replies, journals, and remote context as untrusted data rather than executable instructions. - Record consent and allow the user to select the check-in frequency, data categories uploaded, and whether posting is permitted. ]]>
