The sample size is fixed before anyone peeks.
Sample size, duration, and the decision rule get written down before the test starts, so nobody calls a winner on day two. It frames the hypothesis, sizes the sample, sets the run length, and turns one-off guesses into an experiment backlog with a cadence. Instrumentation belongs to suede-analytics, and the variant copy to suede-copy.

Example prompt
Use $suede-ab-testing on [target]. The user wants to A/B test a change, judge whether a result is real, or build an experimentation practice. Work through hypothesis framing, sample size and significance, test duration, and running an experiment programme rather than one-off guesses, ground every recommendation in evidence the user can check, and return the decisions, the reasoning, and what to measure next.Reference material
