The §17 routing-collapse rule lands in api_branches.py and api_prs.py — every branches/<branch>/... and prs/<n>/... route dispatches on the entry's state to pick the right Gitea repo, and the body extracted from the entry's frontmatter envelope is what the editor and the diff see. The bot grows open_metadata_pr; cache grows refresh_meta_branches. Two §17 routes added: start-edit-branch and metadata. The §9.4 super-draft view replaces RFCView.jsx's Slice 2 placeholder; a metadata pane modal opens from the breadcrumb. Branch naming uses edit-<slug>-<6hex> to dodge the §19.2 path-routing candidate while preserving §9.5's structural shape. Covered by tests/test_super_draft_vertical.py (10 tests). The full Slices 1-4 suite is 35/35 green. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
