## Plan

- **Anchor:** graduated Solution Design `coauthoring-native-surfaces.md` v0.2.1 (content repo, on main) — R2(a), ELIGIBLE per `check-issue-eligibility.sh`; 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` — 9 tasks in §7.1 rung-4 order — and land it (no §9 web pipeline: VS Code extension, spec §7.2; done = merged + suites green + rung-3 smoke).
- **Isolation:** sessions 0061/0062/0063 live-concurrent; 0062 occupied the primary checkout → claim refused shared tree (plugin #134) → EnterWorktree `session-native-surfaces-exec`, branch renamed `session-0065`.
- Approved deliberate changes carried by the plan: INV-18 retirement (no machine-landing baseline advance); D15 deferred as issue #69.

## Pre-state

- Plugin repo `main` at `ef61b14` (0064's plan-archive commit); clean; 265 unit + full host E2E green at baseline (verified before any work).
- Content repo `main` at `ddaf3b0` (0064 lineage merged); local content clone behind origin + carrying other sessions' uncommitted drafts — never touched; spec read via `git show origin/main:`.

## Arc (turn-by-turn, compressed)

1. **Init:** goal recovered from memory (0064 note). Claim dry-run → shared-checkout refusal → worktree isolation → claimed **0065** (`26b2212`). Anchor gate: ELIGIBLE (R2a). Baseline verified green.
2. **Execution model:** superpowers:subagent-driven-development — fresh implementer subagent per task, task-scoped reviewer (spec + quality verdicts), fix subagents on findings, re-review loops; durable ledger `.superpowers/sdd/progress.md`; final whole-branch review at the end. Models tiered (sonnet implementers; opus for risky-diff reviews; fable for the final review).
3. **Task 1 — CoeditingRegistry (INV-10 gate):** `2597cba`; review found untested `syncContext` context-key derivation (plan-mandated gap) → fix `de83757` (11 unit tests). Approved.
4. **Task 2 — baseline router (INV-7):** `447a117`. Deviations approved by review: `.git/logs/HEAD` reflog watcher nudging `repo.status()` (vscode.git's watcher missed external commits in the host; change detection still keyed off `state.HEAD.commit`), E2E suites gaining enter-calls early. Machine-landing advance deleted; `markReviewed` replaces `pinDiffBaseline`. Approved.
5. **Task 3 — native diff surface:** `cf65528` (QuickDiff, `cowriting-baseline:` provider, Review Changes, status bar, pure `countLineHunks`). Approved.
6. **Task 4 — gate every surface:** `a323b82`; review confirmed a PUC-7 restore-on-enter gap (proposals/attribution) → fix `a36353d` (registry subscribers + regression E2E verified fail-without-fix). Approved.
7. **Plan-file repair:** fused `---### Task 5` heading broke the task extractor → `f23fc4a`.
8. **Task 5 — EditFlow extraction:** `ad5d34b`; review caught a real regression (palette accept/reject-all no longer repainted an open review panel) → fix `8fbbe45`. Approved.
9. **Task 6 — comments-first ask loop:** `75f4a3c`; review found a **Critical**: `cowriting.edit`'s no-selection route (⌘⌥E) dead-ended in the rejecting input stub → fix `c9975ba` (all ask entry points converge on `ThreadController.askClaude`; machine-author guard; offer-WeakMap cleanup). Approved. `editInstructionInput.ts` deleted.
10. **Task 7 — built-in preview annotations:** `17fc01e` (pure markdown-it plugin; sentinel machinery generalized 3-way, backward-compatible — 84/84 old tests unedited; render-wrapper approach correctly replacing the brief's per-token rule; mermaid rendering via `markdown.previewScripts` — Q4 confirmed). Approved; intra-diagram diff scoped out by the implementer.
11. **Task 8 — webview sunset:** `2170a0d` (−1472 lines; coverage moved in-commit, arithmetic reconciled exactly). Review flagged the Task-7 scope-out as an unsanctioned INV-29 retirement + `renderReview` going production-dead. **Adjudication:** plan T7 §2.6 mandated the re-emit and its stop condition never triggered → fix `705de31` (diffMermaid wired into the fence path, 6 ported unit tests) + hardening `ff42b5a` (body-matched queue; misalignment degrades to verbatim; parse-less re-render reset). `renderReview` kept deliberately (see Deferred decisions). Approved.
12. **Task 9 — full-loop E2E + smoke:** `22c9da0` (PUC-7→8→2→1 walk; `scripts/smoke-native-loop.mjs` + `npm run smoke:native`, operator-run). Review verified the implementer's adjudication (interior tweak → anchor orphans by contract; Keep-by-id survives) and surfaced a **pre-existing INV-5 gap** (reject-after-interior-edit) → plan text corrected (`17366a4`) + **issue #70 filed** (bug P2).
13. **Final whole-branch review (fable):** verdict "with fixes" — Critical (preview-annotation host leaked past INV-10: wrong-doc annotation + stale-after-exit), Important (thread contextValue conflation made Resolve/Reopen permanently unmatchable once Claude replied; coedited docs opened post-activation never got a baseline) → ONE fix wave `0d69a29` (all three at root + regression E2Es + fold-in minors + polish). Re-review: full when-clause state matrix verified, no double-establish race, **Ready to merge: Yes**. **Issue #71 filed** (surface-polish batch).
14. **Ship:** final verification (typecheck, 301 unit, 90+5 E2E, build — all green) → pushed → **PR #72** → **squash-merged to main `935fcc3`** → remote branch deleted → plan re-archived to content repo (`b0687b6`).

## Deferred decisions

- **`renderReview` left in place though production-dead after the Task 8 webview sunset.** The old F10 pure render engine (`renderReview`/`renderOp` in `trackChangesModel.ts`) lost its last production consumer when `trackChangesPreview.ts` was deleted; three E2E suites (authorship, s48PinClean, undoMarks) now probe it directly as a pure module via a test helper. I kept it (tested pure module, INV-33 documentation value, low carrying cost) rather than deleting + reworking those suites mid-migration. Operator may prefer deletion as a follow-up cleanup.
- **INV-29 mermaid-diff parity adjudicated as plan-mandated, not retired.** Task 7 scoped out the F7.1 re-emit for testability; the plan's stop condition (previewScripts unworkable) never triggered, so I dispatched a fix to wire `mermaidDiff` into the preview fence path rather than accepting the silent retirement. Judged from plan T7 §2.6 + the plan's spec-coverage self-check.

## Cut state

- Plugin `main` = `935fcc3` (PR #72 squash). Working tree clean. Remote `session-0065` deleted; **local branch ref `session-0065` remains** (squash → plain `-d` refuses; operator has preferred manual cleanup of such refs).
- Content repo `main` = `b0687b6` (plan re-archived with in-execution edits: heading fix + Task 9 wording correction).
- Suites at HEAD: typecheck · 301 unit · 90 + 5 host E2E (1 env-conditional #54 undo-probe pending on some runs) · esbuild — all green.
- Issues: **#70 filed** (INV-5 reject-after-interior-edit, bug P2), **#71 filed** (surface polish, task P3); #69 (D15) pre-existing.
- Sessions 0061/0062/0063 still INPROGRESS (other Claude sessions); their checkouts/branches untouched.

## Operator plate

1. **`npm run smoke:native`** — rung-3 real-SDK smoke through the comment loop (one green run completes the plan's definition of done; report it to this transcript's home if you want the record complete).
2. **Mermaid-preview GUI smoke** — open a coedited doc with a changed ```mermaid fence in the built-in preview; confirm diagram renders with cwAdded/ghost styling + legend (previewScripts path isn't E2E-queryable).
3. Optional cleanup: `git branch -D session-0065` in the plugin clone; delete the now-merged worktree leftovers if any; #71 when convenient.
