The §8.11 manual-edit card was a stub — "{N} paragraphs edited
directly" plus a countdown and a Save-now button. The spec says the
card should grow one inline word-diff per touched paragraph as the
contributor types, in the same green/red register the Phase 3 accepted
overlay uses. Phase 5 lands that.
In RFCView.jsx, the 800ms-debounced handleEditorUpdate now computes a
per-paragraph token diff alongside the existing paragraph count and
stores both on manualPending. Baseline is the same Phase 4 gutter
source — originalSourceLinesRef.current, the last server-confirmed
body split on blank lines — so the card resets to empty the same
moment the gutter clears (accept/decline/manualFlush/branch-switch).
In ChangePanel.jsx, diffWords is exported (it was already the AI
card's inline-diff engine — token-level LCS over a whitespace-
preserving /(\\s+)/ split, ~30 lines, no runtime dep). The manual
card consumes the same tokens. Wholly-inserted paragraphs render as
all-insert blocks; wholly-deleted paragraphs as all-delete blocks.
Visual register is intentionally shared with Phase 3's preview
overlay: same #dcfce7/#166534 inserts, same #fee2e2/#991b1b
strike-through deletes. Selectors are scoped under .change-manual-diff
rather than reusing .markdown-preview .tracked-* since the card lives
outside the preview surface.
Pre-fancy stance, matching Phase 4's gutter: the diff is index-aligned
against the baseline, so adding a paragraph in the middle lights up
the rest of the doc. Tolerated as the "you've touched stuff below this
point" cue. An LCS-anchored future pass can fix it.
Verification gap matching Phases 2/3/4: backend was not running this
session, so the live RFCView → real-branch flow wasn't exercised.
Drove the Vite preview sandbox instead — mounted ChangePanel with a
hand-built diffs payload, confirmed three blocks render (mixed edit,
wholly-inserted, wholly-deleted), inserts/deletes carry the expected
computed colors, no console errors. Backend integration suite still
green (125 passed).
Per the §19.1 brief: the three-column shape (§8.1) opens on main
in discuss mode (§8.2), supports the §8.3 discuss-vs-contribute
flip on non-main branches, hosts §8.4's per-branch chat with AI
participation (§18's <change> protocol → §8.14 changes rows), the
§8.8 change-card panel with §8.9 accept/decline/edit-before-accept,
the §8.10 tracked-change markup + DiffView toggle, the §8.11
manual-edit flushes with the stale-change mechanic, the §8.12
range and paragraph sub-threads, the §8.13 flag affordance, and
the §8.14 discuss-mode buffer.
Backend: bot.py grew per-RFC-repo write ops (cut_branch_from_main,
commit_accepted_change with the structured original/proposed/reason
body and Change-Id + Source-Message-Id + On-behalf-of trailers,
commit_manual_flush, ensure_rfc_repo_seed). cache.py grew
refresh_rfc_repo and the webhook dispatches on repository.full_name.
providers.py and chat.py port the §18 carryovers — multi-provider
LLM abstraction and SSE-streaming chat against the §5 threads /
thread_messages / changes schema. api_branches.py mounts the §17
branches/<branch>/* and threads/<thread_id>/* routes with the §6
/ §11 permission checks inline.
Frontend: RFCView.jsx rebuilt as the §8 surface; Editor.jsx,
ChatPanel.jsx, ChangePanel.jsx, PromptBar.jsx, SelectionTooltip.jsx,
DiffView.jsx, ModelPicker.jsx, modelStyles.js lifted from the
prototype and adapted to the canonical schema.
Covered by `backend/tests/test_rfc_view_vertical.py` — eleven new
integration tests against an extended FakeGitea (PUT contents,
POST orgs/{org}/repos, seed_rfc_repo): main-view read,
promote-to-branch, accept (with and without edit-before-accept),
decline, manual flush + system message, flag creation, visibility
flip, anonymous read-but-no-contribute, stale-change refusal, and
the chat-streaming path with a fake provider injected. The 5
Slice 1 tests continue to pass alongside.
