Close an experiment cycle for a bootstrapped B2B SaaS — read what was actually observed, update `.founder/experiments.md`, and choose the next step without treating a technical ship as commercial validation. Use this when an observation window has ended, a complement hands work back, the founder asks "did that work," "what should we do next," or a session resumes mid-experiment. Do not use it for a first diagnosis (founder-start), to decide persist vs. pivot vs. shut down as a strategy exercise (founder-pivot), or to start a new acquisition push (founder-growth) — especially not because churn is high.
