fpf-problem-solving

First Principles Framework (FPF) — thinking amplifier. Use when user wants to think through a complex problem, architect a system, evaluate alternatives, decompose complexity, classify problems, define quality attributes, plan rigorously, apply an FPF pattern to a first useful result, decide under uncertainty, establish causality, reason about time and trends, describe or synthesize architecture, check mathematical model fit, distinguish relation kinds or occurrences, govern ontic/U-kind admission, publish multi-view artifacts, refresh SoTA packs, trace provenance, or improve pattern quality. Also triggers on: FPF, bounded contexts, SoTA packs, assurance calculus, decision theory, causal reasoning, temporal reasoning, architecture description, modularity, constraint-governed unfolding, narrative rendering, structural adequacy, cultural evolution, quality gates, lexical discipline, FPF Parts A-I. Not for simple task planning, general philosophy, or Agile unrelated to FPF.
