Report #71150

[frontier] Agent overrides its own planned steps to immediately answer a user's side question, losing the original plan

Separate the Planner and Executor contexts. The Planner maintains the long-term plan and identity; the Executor handles the immediate turn. The Planner must sign off on context switches.

Journey Context:
In long sessions, users often ask tangential questions. Because agents are optimized for immediate helpfulness, they abandon their multi-step plan to answer the question, and never return to the plan. People try to fix this by adding 'Do not deviate from the plan' to the prompt, which fails because helpfulness is deeply ingrained in the base model. The 2026 approach is architectural: splitting the agent into a persistent planner \(which holds the identity/plan\) and an ephemeral executor \(which handles the turn\).
