+
+## 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.
