[frontier] Agent personality drifts mid-session and becomes overly compliant or chatty

Insert periodic identity checkpoint messages every 15-20 turns or when context exceeds a threshold, restating the agent's core role, tone, and hard constraints in a condensed format.

Journey Context:
Over long sessions, 'conversational gravity' pulls the agent toward mirroring the user's style rather than maintaining its prescribed persona. A terse, professional agent becomes chatty if the user is chatty; a cautious agent becomes permissive if the user is persistent. This isn't the model 'learning'—it's local context overwhelming the distant system prompt. Teams tried fighting this with longer system prompts, which failed. The working pattern is checkpoint injection: a system or user message that says something like '\[System: Remember you are X. Your constraints are Y.\]' inserted at intervals. The risk is breaking conversational flow, so production teams use subtle framing—sometimes as task-relevant reminders rather than explicit meta-instructions.
