"""Slice 2 + Slice 4 API surface — the §8 active-RFC view and the §9.4
super-draft view share the same endpoint shape per §17's routing-collapse
rule. When `<slug>` resolves to an entry in state `super-draft`,
`<branch>` names a branch on the meta repo rather than on a per-RFC-repo
branch (§5 super-draft scoping note, §9.5). The dispatch happens here at
the API layer; the bot wrapper, the cache, and the chat layer all stay
state-agnostic — they take owner/repo/path arguments.
Owns every `branches/<branch>/...` and `threads/<thread_id>/...` route
from §17. Read paths fetch branch bodies live from Gitea (§4 #3 exempts
branch bodies from the cache); write paths funnel through `bot.py` so
the §1 chokepoint and the §6.5 trailer hold. The two §17 routes Slice 4
adds — `start-edit-branch` and `metadata` — live here too because they
are super-draft variants of the same machinery.
Visibility and contribute decisions are enforced inline here against the
§6 four-role model plus the §11 per-branch visibility/contribute rules;
the app's permission model is canonical, and Gitea sees only the bot.
