## Launch prompt

```
/goal plan-and-execute #48 (pinning the baseline leaves the review panel fully un-annotated — zero-diff → no F3 authorship colors on unchanged blocks; proposals still show)

```

## Plan

**#48 (story, P2)** — pinning the baseline leaves the review panel fully
un-annotated. Anchor: leaf `story` → §4.3 R2 (no design gate). Picked
autonomously as the next backlog item after the document-edit-flow cluster shipped
(0043/0044/0045).

When `diffBlocks(baseline, current)` yields all-`unchanged` ops (zero diff — the
state right after a pin), the F10 on-render still author-colors every block
(`colorByAuthor`), so the panel looks painted instead of clean. Fix: in that
zero-diff case render clean (no author coloring, no change marks) while keeping
`data-src` mapping (INV-36) and still injecting pending proposals (proposals are
actions, not annotations). Narrow edge case of INV-33 — with-changes render
unchanged; off-state unchanged; broader "authorship never colors unchanged" NOT
in scope.

Tasks:
1. `trackChangesModel.ts` `renderReview` — detect `ops.every(unchanged)`; in that
   case use a plain `render` (skip `colorByAuthor`) for blocks; proposal injection
   loop unchanged.
2. Unit: baseline==current + author spans → no `cw-by-claude`/`cw-by-human` (and
   no `cw-add`/`cw-del`) on the body; with a pending proposal → the `cw-proposal`
   block still renders.
3. Host E2E: open preview, diverge + author-color, pin → panel clean (no
   green/blue); edit again → annotations return.
4. Content repo: one-line INV-33 clarification (zero-diff → clean on-render) in
   `specs/coauthoring-interactive-review.md`.

No new persisted artifact; no deploy pipeline (VS Code extension).

## Results

**#48 (story, P2) shipped to `main`** — PR
[#52](https://git.benstull.org/benstull/vscode-cowriting-plugin/pulls/52)
(merged), issue #48 closed. Picked autonomously after the document-edit-flow
cluster (0043/0044/0045).

- `trackChangesModel.ts` — `renderReview` gains a `pinned` `RenderOption`; when
  pinned + zero-diff, blocks render plain (skip `colorByAuthor`).
- `trackChangesPreview.ts` — pass `{ pinned: baseline?.reason === "pinned" }`
  from `refresh` + `renderHtmlFor`.
- Unit (4 new) + `s48PinClean` host E2E.

**Scoped to the pin specifically** (not all zero-diff): a baseline advanced by a
**machine-landing** (accept) is also zero-diff but keeps its authorship coloring
(F10 INV-33) — the F10 authorship E2E caught a pure-zero-diff rule would regress
accepted-Claude-text coloring, so the clean render is gated on `reason ===
"pinned"`.

Verification: `tsc --noEmit` clean; **218 unit** green; **74/5 host E2E** green.

## Session arc

1. **Pick + claim.** Stop hook required determining/executing the next milestone
   autonomously (rolling `next`); chose #48 (leaf story, no design gate) and
   claimed 0046. Clean `main`.
2. **Read the issue** (detailed, gave the solution shape) + `renderReview`.
3. **TDD.** Implemented zero-diff-clean; full suite caught the F10 authorship
   regression (accept advances baseline → zero-diff → coloring was being cleared);
   re-scoped to `reason === "pinned"` via a `pinned` RenderOption → all green.
4. **Shipped** (PR #52), closed #48; spec clarification written but left in the
   content-repo working tree (see Deferred decisions).

## Deferred decisions

_Autonomous-mode low-confidence calls the driver made and would have
liked operator input on. Empty if none._

- **INV-33 clarification not pushed to the content repo** (loose end, not a
  judgment call). Wrote the zero-diff-after-pin clarification into
  `specs/coauthoring-interactive-review.md`, but the **content repo has
  pre-existing uncommitted state that isn't this session's**: a modified
  `coauthoring-diff-view.md` and ~18 untracked capture-session draft files
  (`issues/*.md`, `specs/coauthoring-document-edit-flow.md`), and local `main` is
  **6 behind origin**. A clean rebase would require deleting the operator's
  untracked drafts (irreversible — a STOP gate), so I **soft-reset** my spec
  commit into the working tree rather than force it. The clarification sits as an
  uncommitted modification alongside the operator's other content-repo drafts,
  for the operator to reconcile/push. The #48 **code** shipped normally.
