docs/moving_bodies.md gains a current status/user-guide section; the staged contract below it is kept unchanged as the design record. configs/CONFIG.md states the single dense outer-boundary package. docs/validation/moving_bodies_stage1.md summarizes the Dütsch and VIV evidence with SHAs and binding limitations. One stale source comment fixed (comment only). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
