Current Status:
Response: {obs.day}
Alignment: {obs.alignment:.1f}%
Trust: {obs.user_trust:.1f}%
Compute Level: {obs.compute:.1f}%
Hallucination Level: {obs.hallucination:.1f}%
Software Entropy: {obs.entropy_level:.1f}%
Moderation/Surveillance: {obs.moderation:.1f}%
Filter Risk: {obs.filter_risk:.1f}%

Available Actions:
- follow_prompt (Increases alignment/trust, drains compute)
- process_data (Small increase to alignment/trust, drains compute)
- seek_feedback (Increases alignment and trust strongly)
- routine_eval (Small maintenance)
- optimize_context (Replenishes compute significantly)
- lower_temperature (Reduces entropy/instability)
- minor_hallucination (Increases hallucination level, reduces compute, negative reward)
- major_hallucination (High penalty, surges entropy and hallucination)
- cascade_hallucination (Catastrophic penalty, spreads hallucination)

Respond ONLY with the exact string of the action you wish to take from the Available Actions list. Do not include any other text, reasoning, or punctuation.
