## Launch prompt

`/goal brainstorm the Ask-Claude document-edit cluster (#42, #47, #46) and
sequence/design it, starting with #42`

## Plan

Brainstorming session — produce a Solution Design for the **Ask-Claude
document-edit flow**, the cluster of #42 (Ask Claude to Edit Document — entry
points), #47 (block-granularity proposals), #46 (accept-all). Deliverable: one
combined Solution Design (content repo `specs/`), sequencing the three as a
delivery plan **#42 (reach) → #47 (review) → #46 (accept)**.

## Arc

1. **Init.** Claimed session 0041 (`--type brainstorming`), clean pushed `main`
   baseline, seeded the Plan block. Resolved app repos (roadmap = framework repo;
   content = `vscode-cowriting-plugin-content`; no BDD corpus).
2. **Read the cluster.** Read the three capture drafts (#42/#47/#46) in the
   content repo `issues/`. Then ground in code: `package.json` menus/commands,
   `trackChangesModel.ts` (`splitBlocks`/`diffBlocks`/`diffToHunks`/
   `anchorInsertion`/`renderReview`), `trackChangesPreview.ts`
   (`editDocument`/`askClaude`/`runEditAndPropose`), `proposalController.ts`
   (`acceptById`/`accept`→`applyAgentEdit`/`listProposals`).
3. **Key reframe.** F11 (session 0037) **already shipped** the document-edit path
   — `cowriting.editDocument` → `runEditAndPropose({kind:"document"})` →
   `diffToHunks` (word-level, INV-37). So #42 is mostly DONE (remaining = menu
   wiring); #47 swaps the document-branch diff to block-level; #46 loops the
   existing accept seam.
4. **Found a spec-hygiene gap.** The F11 (#43) Solution Design was never graduated
   to `specs/` — INV-35/36/37 live only in code comments + the F11 issue draft.
   Logged as OQ-2 (follow-up), restated the depended-on F11 invariants in the new
   spec.
5. **Locked two forks with the operator** (AskUserQuestion):
   - **D-1** — per-block proposals **preserve unchanged-span attribution** (block =
     decision unit, word = attribution unit; intra-block `diffToHunks` sub-diff at
     accept; INV-40). *Not* whole-block→Claude.
   - **D-2** — ship as **one combined Solution Design**, not three.
6. **Wrote the spec.** `specs/coauthoring-document-edit-flow.md` — business →
   product → engineering, new invariants INV-38..42 (INV-39 supersedes INV-37),
   delivery plan SLICE-1/2/3 = #42/#47/#46, traceability, decisions log. Self-
   reviewed (no placeholders, consistent, scoped). Did **not** invoke
   `writing-plans` (wgl-brainstorming override — the artifact is the spec,
   submitted at finalize; implementation is a downstream session).
7. **Finalize.** Submitted the spec `--status graduated`; memory updated.

## Deferred decisions

- **D-3 (low-confidence driver call)** — sequenced **#42 → #47 → #46** per the
  goal's "starting with #42," **despite #47 carrying the P1 value** ("too much to
  review" is the sharpest pain). The three are code-independent so the order is
  reversible (§7.1); #47 and #42 could swap with no rework if the operator wants
  the P1 review fix to land first. Surfaced at closeout; logged as D-3 in the
  spec §9.
- D-4 (driver) block taxonomy = exactly `splitBlocks`'s units; D-5 (driver)
  accept-all needs no confirmation, button shown ≥2 pending. Both in spec §9.

## Loose ends → next session

- **OQ-2** — graduate the F11 (#43) spec to `specs/` for a clean invariant ledger
  (INV-35/36/37 currently code-only).
- **OQ-1** — whether selection edits should also preserve-unchanged-span
  attribution (out of #47 scope).
- Content-repo local working tree carries pre-existing untracked drafts/specs
  (prior sessions / the Author's) — not landed by this session.

## Next /goal

```
/goal plan-and-execute #42 (SLICE-1 of the document-edit flow — Ask-Claude entry-point menu wiring), per specs/coauthoring-document-edit-flow.md
```
