/reality-check — Mid-epic strategic drift audit

Purpose: at a wave boundary, force the agent who has been deep in the implementation to articulate implemented-reality against claimed-vision, name every gap with evidence, and route the bridge into the planning stack. The canonical failure this catches: 72% of beads done, 0% of the value proposition working end-to-end. Tracker arithmetic measures motion; this skill measures whether the motion still points at the promise.

Use when: a wave boundary lands mid-epic; the operator asks "where are we really"; tracker counts look healthy but nobody can demo the headline feature; or the next wave is about to be planned and needs steering input.

(user-invocable: false is interim — promotion to invocable needs catalog + dispositions rows, a separate one-line change outside this skill's directory.)
