Floor or threshold

A minimum that must be met before an outcome counts as acceptable or the next action is permitted.

The group climb everyone's excited about starts in an hour, and the forecast just wobbled. One person's harness setup looks improvised, another has never done this grade. The pull to launch anyway is enormous, and "it'll probably be fine" is doing all the safety analysis.

A floor or threshold is the reference shape for moments like this: a minimum value or condition that must be met before an outcome counts as acceptable, or before the next action is permitted. Use it when minimum adequacy, safety, readiness, or dignity matters more than any gains above the line. Running it means defining the gate in advance and honoring it: the climb begins only if weather, equipment, experience, and turnaround margin all clear the agreed minimums; any single miss means the group doesn't launch, no matter how good the other three look. What changes: go/no-go stops being a charisma contest at the trailhead and becomes a checklist written by calmer versions of everyone. The two failure modes the spec flags: people optimizing to barely scrape past the floor, and hard thresholds misclassifying noisy near-boundary cases, so add margin or an audit where the signal is fuzzy. Don't use floors for outcomes where more really is better all the way up; that's optimization territory, not gating.
