Produce a PMF Measurement Pack (Markdown in-chat; or as files if requested) containing:

1) Context snapshot (product, stage, decision, timebox, segments, constraints) 2) PMF measurement model (core value moment, active user definition, signal set, thresholds as heuristics) 3) Sean Ellis survey plan + results (sample definition, questions, response counts, “very disappointed” % overall + by segment, top benefits)

4) Behavioral evidence (retention/cohort summary + engagement frequency; instrumentation gaps + how they affect confidence) 5) Reference-customer / advocacy evidence (who is willing to vouch; quotes; counts vs heuristic targets) 6) PMF Scorecard (signals, targets, current state, confidence, evidence links/notes)

衡量產品市場契合度 (PMF) 並產生 PMF 衡量包（Sean Ellis「非常失望」的調查、保留/使用證據、參考客戶訊號和行動計劃）。用於成長團隊評估 PMF、PMF 漂移和發布準備。 來源：liqiongyu/lenny_skills_plus。
