[frontier] Agent personality drifts from defined persona to generic assistant after 40\+ turns

Embed a 'semantic salt'—a unique, high-entropy token string \(e.g., 'Xq9\#mK2'\)—into the system prompt identity definition, and programmatically verify its presence in the agent's self-description every 10 turns. If absent, trigger a hard reset to the anchor prompt.

Journey Context:
Teams tried re-injecting the personality description every N turns, but this creates 'personality whiplash' where the agent oscillates between states. The semantic salt acts as a checksum for identity integrity. It works because models tend to preserve rare tokens longer than semantic meaning \(attention heads show higher activation on rare tokens\). Alternative: using a hash of the system prompt, but this is brittle to minor formatting changes. Tradeoff: requires the agent to support introspection queries.
