## Launch prompt

> Got it. Let's implement the full plugin
> (operator, after driving the rung-2 feasibility spike; context: evolve the shipped
> extension in place onto specs/coauthoring-native-surfaces.md, D17/§6.10/§7.1)

## Pre-state

- Native-surfaces Solution Design at **v0.2.0, draft**, on content-repo branch `session-0063` (session 0063 INPROGRESS, awaiting operator review). Content `main` had never received the 0062/0063 spec lineage.
- Rung-2 feasibility spike: E1/E3/E5 PASS (recorded in v0.2.0); **E2/E4 unvalidated**. Earlier in this same conversation (pre-session), the throwaway prototype `vscode-cowriting-prototype` was rebuilt to drive the FULL v0.2.0 loop (enter → ask-via-comment → pending-in-buffer → tweak → baseline/diff → preview → stop) and the operator drove it end to end.
- Three concurrent INPROGRESS sessions (0061/0062/0063); 0062 occupied the main plugin checkout → this session claimed from an isolated worktree (#134 gate).

## Arc (turn by turn, condensed)

1. **Spike driving (pre-claim, same conversation):** operator drove the walkthrough; two E4 defects surfaced and were fixed live in the prototype — (a) "Make this edit" gated on a nonexistent `commentThreadContextValue` key (real key: **`commentThread`**); (b) Ask-Claude didn't focus the comment input (fixed via **`workbench.action.addComment`**); (c) "cursor must be within a commenting range" → commenting ranges are **cached per document**; re-assigning `commentingRangeProvider` is the only refresh signal. All recorded in the prototype's FINDINGS.md.
2. **Gate + claim:** operator asked to "implement the full plugin" → `wgl-writing-plans` init; claim refused the shared checkout (live 0062) → isolated worktree `vscode-cowriting-plugin-wp`, claimed **0064** (`--type writing-plans`, careful).
3. **Eligibility:** `check-issue-eligibility.sh --for implementation-plan --design …coauthoring-native-surfaces.md` → **ELIGIBLE (R2a)**. Design-readiness: N/A (spec §5.1 = Code directly, no UI design).
4. **Sequencing decision (operator):** fold spike findings first, then plan. Operator confirmed the drive reached step 5+ → **E2 PASS**; E4 **PASS-with-fallback**.
5. **Spec v0.2.1 delta** (content worktree branch `session-0064` off `session-0063`): §6.4 spike-verified API seams (commenting-range refresh, addComment focus, `commentThread` when-key, offer affordances; baseline nested-repo + `state.HEAD.commit` notes), §7.1 rung 2 closed (E2 PASS / E4 PASS-with-fallback; D15 preview-selection half explicitly un-spiked), §7.3 risks updated. Pushed; operator **approved → graduated**.
6. **Plan written** (`superpowers:writing-plans`; codebase mapped via an Explore subagent + direct reads): `docs/superpowers/plans/2026-07-01-native-surfaces-migration.md` — ONE plan, 9 tasks in §7.1 rung-4 order: (1) CoeditingRegistry (INV-10) → (2) baseline router git-HEAD+snapshot (INV-7; **retires INV-18** machine-landing advance) → (3) QuickDiff + `cowriting-baseline:` + Review Changes + status bar (INV-13) → (4) gate every surface → (5) extract EditFlow from the review webview → (6) comments-first ask + comment→reply→offer→proposal loop (D19/D10/D8; sunsets the input webview) → (7) built-in-preview annotations via markdown-it sentinels (D3/D21; Q4 mermaid stop-and-record check) → (8) sunset the review webview + ✓ Keep/✗ Reject copy + README → (9) full-loop E2E + real-SDK smoke (rung 3 folded in). D15 explicitly deferred. Committed to plugin branch `session-0064`, pushed.
7. **Review gate:** operator approved — explicitly accepting the **D15 deferral** and the **INV-18 retirement** — and directed execution to a new session.
8. **Finalize (single approved plan):** content `session-0064` merged → content `main` (landed the whole 0062/0063/0064 spec lineage; flagged), plugin `session-0064` fast-forwarded → plugin `main`; plan archived via `submit-plan.sh` → content `plans/2026-07-01-native-surfaces-migration.md` (ddaf3b0); **issue #69** filed (D15, feature P2, resume context in body); both session worktrees removed; memory updated.

## Deferred decisions

_None — the two judgment calls (D15 deferral, INV-18 retirement) were put to the operator explicitly and approved at the plan gate._

## Cut state

- **Spec:** `coauthoring-native-surfaces.md` **v0.2.1 `graduated`**, on content `main`.
- **Plan:** approved + archived at content `plans/2026-07-01-native-surfaces-migration.md`; also on plugin `main` under `docs/superpowers/plans/`. **Not executed** (by design — writing-plans is terminal).
- **Spike:** complete (5/5); prototype **retained deliberately** (operator: iterate UX there before the real build) — supersedes the spike-plan's delete-when-done for now.
- **Tracker:** #69 (D15 preview-initiated comments, feature P2) parked with full resume context.
- Leftover: merged-but-undeleted local branch refs (`session-wp-native-surfaces` in the plugin clone, `session-0064` in the content clone) — operator declined force-deletion; plain `-d` from a main checkout clears them. Sessions 0061/0062/0063 remain INPROGRESS (0062/0063 will find their content branches already merged).

## Operator plate

- Open the executing session (below) when ready.
- Sessions 0061/0062/0063 are still unfinalized — worth closing out.
- Optional tidy: delete the two stale local branch refs.

## Next session

```
/goal Execute the native-surfaces migration plan (content repo plans/2026-07-01-native-surfaces-migration.md, 9 tasks, from graduated spec coauthoring-native-surfaces.md v0.2.1) end to end
```

(Open with `wgl-executing-plans`; the plan's tasks run 1→9 strictly, each ending typecheck+unit+host-E2E green; Task 9's live smoke is the operator-run rung-3 gate.)
