Upfront design

Route and persistence

A design has request/status frontmatter and a # Design: title. New request → design; draft → first missing section; approved → check next open milestone; another status → BLOCKED. A named revision phase removes later sections only after the user authorizes that revision.

Resolve this skill's absolute anchor. Store new designs at <anchor>/designs/<basename>-<slug>-<YYYY-MM-DD-HHmmss>.md, outside repos. <basename> is the first repo's root directory name. After a path exists, persist approved phases and the ledger through sibling temporary files and atomic rename before advancing. Record request | size | design | phase | approvals | ADR offers | terminal. Keep the ledger at <design>.ledger on AWAITING_USER; remove on other terminals.
