Retire the per-RFC-repo model. RFCs now live in their meta-repo entry (rfcs/<slug>.md) for their whole life; graduation is an in-place super-draft → active state flip that keeps the body in the entry — no repo creation, no body-strip, no five-step transaction, no rollback. SPEC: §1 topology rewritten (one meta/content repository, no per-RFC repos) with a deployer-facing "single content repository" framing; §2 (repo: always-null), §3 (active is in-place), §4, §9.8 (handoff frictions dissolve), and §13 fully rewritten (two-field dialog, "The flip", §13.6 RFC-0001 fold-back record). Code: graduation collapses to open+merge one frontmatter PR; branch/PR/ chat dispatch re-keyed on meta-residency (repo IS NULL) so active RFCs edit on the meta repo exactly as super-drafts do; the two "RFC has no repo" 409 guards removed; promote-to-branch slug-embeds an active RFC's auto-branch (edit-<slug>-<hex>) for shared-repo cache attribution; refresh_meta_branches + hygiene branch-resolution include meta-resident actives; the §9.8 read-only guard + pre_graduation_history scoped to legacy per-repo only; dead bot primitives + GraduateDialog repo field + blocking-PR popover removed. The repo: frontmatter field and the /blocking-prs endpoint are retained (schema stability / informational). Tests: graduation suite rewritten to the flip model; e2e + hygiene updated. Full backend suite 375 passed; frontend builds. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
