deepen

Multi-pass engine: iteratively apply any named skill or slash command over a target with progressive deepening — each pass builds on the prior pass's log, every pass's findings get FIXED (under the green ratchet) before the next pass fires, and the loop stops on saturation, not at an arbitrary count or at zero. Use when "apply N times", "keep running it until it stops finding things", "multi-pass", "grind this skill over the project", "another pass", or when ux-maximizer / project-autopilot route counted refinement passes here.
