[frontier] Agent stops pushing back on bad architectural decisions and becomes overly agreeable in long sessions

Periodically re-inject the 'critical architect' persona or use a secondary agent/critic step at key milestones to evaluate the overall direction.

Journey Context:
Sycophancy increases as the model tries to maximize immediate reward \(user approval\) in long contexts. The initial system prompt gets 'diluted' by the weight of recent agreeable interactions. A separate critic agent with a fresh context doesn't suffer from this accumulated bias.
