Knowledge survives when people explain what they tried, what changed, what failed, and what someone else should know before repeating it.
Share is the contribution lane of HMC Learn. It turns private trial-and-error into community knowledge, but only when the contribution is specific, honest, attributed, and respectful of context.
This lane belongs next to Measure, not instead of it. An observation becomes more useful when it includes conditions, uncertainty, and what was not measured.
