Report #69587

[frontier] Agent gradually shifts personality/tone after 30\+ exchanges without external schema anchoring

Bind identity to external MCP \(Model Context Protocol\) resources with persistent schema validation, not just internal self-description

Journey Context:
Self-description drifts because autoregressive sampling reinforces recent tokens over original instructions. MCP provides external canonical state that survives session restarts and context compression. Common error is storing personality in vector DB without strict schema validation. This pattern separates volatile conversation history from immutable identity resources.
