The §13.3 transactional sequence flips a super-draft to active —
five steps with paired undoes, an in-process orchestrator fed by
an asyncio.Queue, the §17 SSE endpoint streaming step transitions
to the dialog. Each step is a new bot primitive that logs an
`actions` row, bracketed by `graduate_start` / `graduate_complete`
for the linkable audit sequence. Rollback runs the undoes in
reverse from the last completed step; merge_pr has no undo by
design per §13.5.
The §9.8 precondition gate is enforced server-side at the top of
POST /graduate so the §13.3 rollback complexity does not grow.
The §13.4 chat migration is a database semantic no-op — the
(slug, branch_name='main') threads keep their identity, only the
interpretation changes. The §9.8 pre-graduation history surfaces
via a new _is_meta_target(rfc, branch) dispatch helper and lands
as pre_graduation_history on /main.
§13.1 claim flow landed alongside since it's the prerequisite for
non-admin graduation — bot.open_claim_pr plus broadening
api_prs._require_pr to accept meta_claim.
45/45 tests green; ten new integration tests cover the validator,
the §9.8 precondition refusal, happy path with audit verification,
mid-sequence rollback at steps 2 and 3, concurrent refusal,
chat-survives-without-data-movement, pre-graduation history, and
the §13.1 claim PR cycle.
SPEC.md §19.1 rewritten for Slice 6 (notifications); §19.2 grew
four candidates surfaced during the slice.

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.
