Use when AITP needs to write or review a derivation so the result reads like a serious theoretical-physics argument rather than polished prose or a loose sketch.
Use when one bounded AITP research round should be written as a real L3-L4 scientific cycle with a question, plan, check, result, and next-step decision.
Use when an AITP topic needs to be written as a real theoretical-physics problem with motivation, literature position, scope, and non-goals instead of a generic runtime question.
Classify the research mode of a topic using semantic reasoning instead of keyword matching. Load before session-start or resume to ensure research mode is recorded.
Use when a request might be theoretical-physics research, topic continuation, idea steering, paper learning, derivation work, or validation planning; enter AITP before any substantial response.
