mb-map-codebase — Brownfield: Repo → Memory Bank

• What it does: scans an existing repository, merges evidence from scoped workers, and writes as-is Memory Bank docs.
• Use it when: code already exists and you need a reliable baseline before planning changes.
• Input: repository root plus an initialized .memory-bank/.
• Output: product, architecture, testing, runbook, and contract docs that describe the current system without speculative backlog generation.

Preconditions

• You are in the repo root.
• .memory-bank/ skeleton exists (if not, run mb-init).
