Report #102809

[frontier] Agent loses the original objective while executing deep sub-tasks in a long session

Pin the original objective in a persistent system/developer message and add a cheap secondary observer model that scores each proposed action against the objective. If the score drops below threshold, force a re-plan from the root goal rather than continuing local optimization

Journey Context:
Agentic drift happens when sub-steps pull the agent away from the user's intent. Summaries and compaction can dilute the original goal. An observer model gives a leading, low-cost signal before output quality collapses, and avoids the common mistake of letting the agent self-grade its own drift
