Session 0025.0 — Transcript

App: vscode-cowriting-plugin Start: 2026-06-11T12-51 (PST) · End: 2026-06-11T13-21 (PST) Type: planning-and-executing Driver: Ben Stull (with Claude / Opus 4.8) Status: FINALIZED

Launch prompt

/goal next → the session gate resolved the stored next-goal from memory: plan-and-execute F8 (out-of-workspace authoring) from the graduated spec specs/coauthoring-out-of-workspace.md (Feature #25, brainstorming session 0024).

Pre-state

• main clean but 5 commits behind origin/main (session-history transcripts 0022/0023/0024 + the 0025 placeholder); fast-forwarded.
• An in-flight predecessor: session 0024 (brainstorming, specced F8) still --INPROGRESS in sessions/0024/. Sequential handoff (spec → code, no code-surface overlap) → noted and proceeded in autonomous posture.
• The F8 spec sat untracked at specs/coauthoring-out-of-workspace.md (the brainstorming artifact); used as the read reference, left untracked (specs don't belong in a code PR).
• Baseline: 130 unit tests green.

Plan

Wrote the implementation plan with superpowers:writing-plans → docs/superpowers/plans/2026-06-11-f8-out-of-workspace.md (12 TDD tasks across the spec's four slices). Executed inline (sequential dependencies, shared files) with superpowers:test-driven-development.

Turn-by-turn arc

1. Classify + claim. /goal next → planning-and-executing → wgl-planning-and-executing claimed session 0025, fast-forwarded main, confirmed the resume pointer.
2. Read the spec + the whole authoring surface (store, baselineStore, workspacePath, the three controllers, extension wiring, versionGuard, model, package.json, e2e harness) before planning.
3. SLICE-1 (Tasks 1–5): SidecarStore interface; GlobalSidecarStore (sha256-keyed disk for out-of-folder file:, in-memory for untitled:; INV-16 throw + anchor prune); SidecarRouter (keyOf + per-key routing); isAuthorable + widened selectionRejection. TDD per file; 18 new unit tests.
   • One hiccup: a **/ glob inside a JSDoc block comment contained */ and closed the comment early (esbuild "Unexpected ."). Reworded to .threads/.
4. SLICE-2 (Tasks 6–7): re-pointed VersionGuard + the three controllers from CoauthorStore onto the router; gate → isAuthorable; key via store.keyOf(docIdentity(...)); rootDir → string | undefined (git email omitted when no root). CoauthorStore left untouched.
5. SLICE-3 (Task 8): wired the router in extension.ts; removed the no-root early-return + command stubs so authoring is live folder-less (F6 #19 precedent); renderIfOpen → isAuthorable; widened the editor-context menus to untitled; exported sidecarRouter on CowritingApi. 150 unit tests green.
6. SLICE-4 (Tasks 9–12): host E2E for out-of-folder file + untitled + in-workspace byte-for-byte regression; rewrote the no-workspace suite (authoring now real folder-less); docs/MANUAL-SMOKE-F8.md + README F8 note. Full E2E: 36 passing with-workspace + 5 passing no-workspace.
7. Self-review: model.ts / mergeArtifacts.ts / store.ts confirmed untouched (INV-2/24/25 by construction).
8. Ship: PR #26 (f8-out-of-workspace → main) created + merged via the Gitea API; branch deleted; main fast-forwarded; 150 unit tests green on the merged tree. Issue #25 closed. Plan archived to the content repo plans/2026-06-11-f8-out-of-workspace.md.

Cut state

• F8 merged to main (PR #26); issue #25 closed; plan archived.
• Tests: 150 unit + 41 host E2E green.
• VS Code extension → no PPE/prod pipeline stage (no deployable UI); spec §7.3 declares it non-shippable. Done = merge + tests green.

Deferred decisions

Autonomous-mode low-confidence calls surfaced for the operator:

• Controllers typed SidecarRouter (concrete), not the bare SidecarStore interface. The spec (§6.4) wrote store: SidecarStore + store.keyOf, but keyOf/sidecarPath live on the router, not the 4-method storage interface (which CoauthorStore/GlobalSidecarStore implement). Typing controllers to the concrete router is the faithful, fully-typed realization. Least-churn, revisitable.
• Editor-context menus widened to untitled (resourceScheme == file || resourceScheme == untitled) so the right-click affordance matches the widened gate — a small UX call not spelled out in the spec.
• Session 0024 left unfinalized (out of this session's scope). The brainstorming predecessor that specced F8 is still --INPROGRESS in sessions/0024/; it needs an adopt-and-finalize pass. Its spec artifact sits untracked at specs/coauthoring-out-of-workspace.md, and the spec home is ambiguous (app.json lists specs under the main repo; submit-spec.sh targets the content repo). Flagged, not resolved.
• Issue hygiene (prior sessions): #21 (F7) still open though F7 shipped (PR #23); Epic #1 still open though memory records it fully shipped. Not touched.

Next-session prompt

/goal plan-and-execute #22 (F7 intra-diagram mermaid diffing — node/edge-level diff beyond the whole-diagram "changed" badge), per Feature #22

Read f8-out-of-workspace-shipped for the SidecarStore/router surface and the open F8 follow-ups (untitled→saved migration, re-key/recover gesture). Consider an adopt-and-finalize pass on session 0024 first (it's a one-step finalize), and the #21/#1 issue-status hygiene.
