Part II — RFPA: The Frame You Set Before Growth

Part II is about the four moves you make before you allow a system to take a single step. RFPA — Recover, Field, Principal, Assumption — is not a process you run; it is a frame you establish. A recurrence with the wrong base cases produces a perfectly valid, perfectly wrong sequence forever. The frame determines whether everything downstream can be trusted. This part treats each RFPA move in turn, then assembles them into a single preflight you can run before opening any new Infinity Engine loop.

CANON. Throughout this part, RFPA expands only as Recover, Field, Principal, Assumption, and never drifts. The four moves are framing, done once per loop (and revisited when assumptions change), as distinct from the AVPT execution beats of Part III, which cycle repeatedly.
