iterate-gtm-weekly — One number, one fix, one post

Degree of freedom: MIXED. Which lever to pull [HIGH freedom]; the five-line review, the single-experiment rule, and the scorecard update [LOW freedom — run exactly].

The loop after workflow-gtm. Thirty minutes a week: read what the funnel did, name the one step that lost the most, ship one experiment against it, publish one thing, write it down. iterate-post-launch owns production defects; this owns growth.
