## Launch prompt

```
Examine the existing vs plugin, the prototype, and the half-baked spec that I used Opus to create and make a recommendation for a VS Code experience that allows humans and machines to collaborate on a document, with the machine making suggestions based on human input and the human able to approve, reject, or modify those suggestions. This should use as many VS Code UX paradigms as possible, use as many existing VS Code components or extensions, but create custom components/UX when needed. You can assume this is just Claude as the 'machine' to start

```

## Plan

> Anchor: design-only north-star recommendation (no tracker anchor; lineage =
> Epic #1 / F1–F12 + session 0062's `coauthoring-native-surfaces.md` draft —
> same anchor treatment 0062 recorded)

1. Examine the three inputs: the shipped plugin (F1–F12 code on `main`), the
   prototype, and the half-baked Opus-authored spec (untracked `specs/` in the
   primary checkout).
2. Identify/confirm the anchoring issue (§4.3 R1 gate) — capture one if none fits.
3. Walk the consequential UX decisions with the operator (AskUserQuestion
   checkpoints), grounded in native VS Code paradigms vs custom components.
4. Draft the recommendation as a Solution-Design spec in the content repo's
   `specs/`; whole-document review at the Gitea render URL.

## Session record (running)

- Examined the three inputs: shipped plugin (F1–F12 inventory), prototype
  (`vscode-cowriting-prototype` = rung-2 spike: E1/E3/E5 PASS — key finding:
  CodeLens does not render in a diff editor; E2/E4 unbuilt), and the 0062 draft
  `coauthoring-native-surfaces.md` v0.1.0 + companion spike plan.
- Recommendation delivered + four forks decided with the operator
  (AskUserQuestion checkpoints, all recommended options chosen):
  1. Review model = **in-buffer pending changes + per-hunk CodeLens** (D18;
     supersedes multi-diff Keep/Undo; amends INV-5/INV-12; resolves Q2/Q7).
  2. Packaging (Q1) = **evolve the shipped extension in place** (D17; §6.10
     rewritten from "greenfield").
  3. Ask surface = **comments-first** (D19; split-pane input webview sunsets).
  4. Artifact = **amend the 0062 spec to v0.2.0** on content-repo branch
     `session-0063` (0062's working tree untouched). Also D20 (tweaks × per-hunk
     decisions), D21 (D11 → shipped reality).
- Spec v0.2.0 + spike-spec status committed (`431ebeb`) and pushed to
  `session-0063`; whole-document review handed to the operator at the Gitea
  render URL (terminal gate).

## Deferred decisions

- Proceeded past the concurrent-session warning (0061/0062 both INPROGRESS,
  placeholder-only claims from 2026-06-27) because the operator explicitly
  launched this session; isolated in worktree `session-0063` per #134/§5.4.

_Autonomous-mode low-confidence calls the driver made and would have
liked operator input on. Appended as the session runs; surfaced at
finalize. Empty if none._
