## Launch prompt

> The last session should have set a goal. If not, find the spec that we should be implementing

## Plan

- **Anchor:** graduated Solution Design `coauthoring-native-surfaces.md` v0.2.1 (content repo, on main) — R2(a); tracking Epic #1 lineage, sessions 0062 (spec) → 0063 (v0.2.0) → 0064 (spike + plan, approved).
- **Goal:** execute the reviewed implementation plan `plans/2026-07-01-native-surfaces-migration.md` (content repo) — 9 tasks in §7.1 rung-4 order (registry → baseline router → QuickDiff/diff surface → gate all surfaces → EditFlow extraction → comment loop → built-in-preview annotations → sunset review webview → full-loop E2E + real-SDK smoke) — and ship via §9 (no deploy pipeline: VS Code extension, no flotilla; done = merged to main + tests green).
- **Isolation:** running in worktree `.claude/worktrees/session-native-surfaces-exec` (branch `session-0065`) — sessions 0061/0062/0063 are live-concurrent and 0062 occupies the primary checkout.
- Approved deliberate changes carried by the plan: INV-18 retirement (no machine-landing baseline advance); D15 deferred as issue #69.

## Progress log

- Baseline (worktree, fresh off origin/main): typecheck + 265 unit + full host E2E green before any work.
- Task 1 CoeditingRegistry: complete (2597cba + de83757 test fix; review clean).
- Task 2 baseline router (INV-7, INV-18 retirement): complete (447a117; review clean; reflog-watcher hardening deviation approved by review).
- Task 3 native diff surface (QuickDiff/reviewChanges/status bar): complete (cf65528; review clean).
- Task 4 INV-10 gating of all surfaces: complete (a323b82 + a36353d PUC-7 restore-on-enter fix; review clean).
- Plan file edit: fixed fused `---### Task 5` heading (f23fc4a).
- Tasks 5–9: in progress via subagent-driven development; per-task reviews + final whole-branch review; Minor findings ledgered in `.superpowers/sdd/progress.md`.

## Deferred decisions

_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._
