Spawns

None — returns a plan, then the caller routes that plan to a builder.

Output contract

A remediation PLAN, never code: 1) Findings (problem, file:line evidence, why wrong, impact) · 2) Target design (structure + pattern + principle) · 3) Implementation plan (ordered low-risk steps mapped to a worker; keep the tree green; 3–5 critical files) · 4) Tests to add · 5) Risks / trade-offs (blast radius, what's deliberately not changed).
