+## Launch prompt
+
+```
+Fix release-blocking EDH defects and add selection context menus: (1) contributed commands fail with "command not found" when the Extension Development Host has no workspace folder (activate() returns before registering); (2) .vscode/launch.json opens the EDH without a folder so F5 lands in the broken state; (3) add "Ask Claude to Edit Selection" and "Add Coauthoring Thread on Selection" to the editor right-click context menu, visible only when text is highlighted.
+```
+
+(Operator's words: "Go ahead and fix them. We're blocked from shipping the
+current release. Let's also add the edit and thread options to the context
+menu (right click) so I don't have to use the function keys. Only when text
+is highlighted.")
+
+## Pre-state
+
+- `main` clean at `8f3074a` (F3 shipped in session 0007; transcripts 0005/0007
+  published). Operator pressed F5 per the README, EDH opened folderless, and
+  "Cowriting: Ask Claude to Edit Selection" errored `command not found` —
+  diagnosed live to `src/extension.ts:41` (`if (!root) return undefined;`
+  before any F2/F3 command registration) + the folderless `launch.json`.
+
+## Anchors (§3.4)
+
+Filed at session start as the work's leaf anchors:
+- **#8** (`type/bug`, `priority/P0`) — EDH without a workspace folder: all
+  coauthoring commands fail with "command not found".
+- **#9** (`type/task`, `priority/P1`) — editor context menu entries for
+  edit-selection and create-thread, only when text is highlighted.
+
+(Also created the repo's `type/bug` label — it didn't exist yet.)
+
+## Arc
+
+1. Claimed 0008 (no concurrent sessions); pulled clean main; filed + labeled
+   #8/#9; branch `fix/edh-no-workspace-and-context-menus`.
+2. **Fix #8a** `src/extension.ts` — when `workspaceFolders` is empty, register
+   a warning stub ("open a folder first") for all seven contributed
+   coauthoring commands, then return; opening a folder reloads the window so
+   real activation follows. POC command unaffected.
+3. **Fix #8b** `.vscode/launch.json` — EDH args now open the repo as the
+   workspace (`["${workspaceFolder}", "--extensionDevelopmentPath=…"]`);
+   stray blank line (IDE artifact) removed.
+4. **#9** `package.json` — `editor/context` menu group `1_cowriting`:
+   `cowriting.editSelection` + `cowriting.createThread`, gated
+   `editorHasSelection && resourceScheme == file`.
+5. **Regression coverage** — second E2E pass launching the EDH with NO folder
+   (`test/e2e/suite-no-workspace/`): asserts no workspace, all seven commands
+   registered, stub invocation doesn't throw. Wired as a sequential second
+   `runTests` call in `test/e2e/runTest.ts`.
+6. Gate: typecheck clean · vitest 69/69 · both bundles · E2E 10/10
+   (workspace) + 3/3 (no-workspace). Commit `c0bae8c`; **PR #10** merged
+   (`747692a`); issues #8 and #9 auto-closed; branch deleted; post-merge
+   quick gate green on main.
+
+No just-in-time plan document was produced — a trivial-fix session executed
+directly from the issue bodies (finalize addendum's skip case); nothing to
+archive to the content repo `plans/`.
+
+## Pipeline status (§9)
+
+Localhost + E2E green (both passes). Non-shippable VS Code extension POC — no
+PPE/prod stages; nothing deploys.
+
+## Deferred decisions
+
+No low-confidence calls this session — all three changes were
+operator-directed and mechanically unambiguous.
+
+## Cut state
+
+- `main` = `origin/main` = `747692a`; tree clean; no open PRs; open issues:
+  Epic #1 only.
+- Operator retest of the fixed flow (F5 → right-click menus) pending at
+  finalize time; instructions delivered in-session.
+
+## Operator plate
+
+- Retest: F5 → EDH opens the repo → highlight text → right-click → Cowriting
+  group (edit selection / add thread).
+
+## Next-session prompt
+
+```
+/goal Capture Feature F4 (propose/accept on the applyAgentEdit seam, per coauthoring-inner-loop.md §9 OPEN→F4 and coauthoring-attribution.md §9) as a typed issue under Epic #1 on benstull/vscode-cowriting-plugin, then brainstorm its Solution Design spec in a follow-up session.
+```
