Appetite and Review Mode split into two separate questions. Previously, setup:15 asked both appetite and review mode in a single ask_user_question call (or the LLM was prompted to combine them), conflating two orthogonal decisions. Now setup:15 asks Appetite only (Pattern 7) and setup:16 asks Review Mode only (Pattern 8), with explicit warnings against combining them. The start-message.ts activation message no longer says "Appetite & Mode declaration" — instead lists them as separate items.
Added guardrails against time/calendar references in appetite options. The original Shape Up concept equates appetite with calendar time (6 weeks), but stelow explicitly departs from that model — appetite caps preparation depth, not duration. The new "Guardrails for LLMs" section in Pattern 7 prohibits time-based framing (e.g., "Lean = 1 week") and explains that appetite is about scope depth only.
