Session 0065.0 — Transcript

App: vscode-cowriting-plugin Start: 2026-07-02T06-31 (PST) End: 2026-07-02T16-10 (PST) Type: executing-plans Posture: yolo Claude-Session: 32dcda47-7361-4fa7-8145-9d118b5de3cc Checkout: /Users/benstull/git/benstull.org/benstull/vscode-cowriting-plugin/.claude/worktrees/session-native-surfaces-exec (isolated worktree, branch session-0065) Status: FINALIZED

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), 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.

Next-session prompt

/goal Plan and execute #70 — fix the INV-5 reject-after-interior-edit gap (proposalController revertInPlace orphan path); fix directions in the issue body
