Task Summary Reuse Overlay

This overlay is the first auto-mutable low-risk improvement surface.

Intent

Use this overlay to improve task summaries and handoff quality when the repository already has a clear execution plan. It must not alter control-plane routing, permissions, or review gates.

Allowed Scope

• adjust summary phrasing inside the allowlisted low-risk overlay namespace
• add non-governance reusable checklist content
• keep changes additive and narrowly scoped
