Problem
The skillEffectiveness signal's attribution window (50 stories) retains invocation records from skills that were retired and removed from disk during the command-surface simplification (flow:author, flow:judge, flow:status, flow:board, crew:board, flow:accept-proposal). These ghost entries appear with 0 effectiveness_ratio in the per_skill map and are structurally indistinguishable from active skills that fired but produced no useful work. A retro analyst following the skill-effectiveness discipline would incorrectly draft skill-retire proposals for skills that have already been deleted. The current cycle bundle contained 6 such ghost entries, each with 0 useful_fire_count.
Tool area
computeSkillEffectiveness / retro analyst input bundle
Suggested direction
Filter per_skill entries to only those whose skill_path resolves to an installed skill file on disk at the time the effectiveness helper runs, or tag each entry with an installed boolean flag so the retro analyst can skip uninstalled skills without having to probe the filesystem.
