Issue #43 closed; > branch deleted; plan archived to the content repo. ## Launch prompt ``` plan-and-execute #43 (F11), per specs/2026-06-12-f11-preview-toolbar-interaction-surface.md. Start with SLICE-1 (Pin baseline button + unhide pinDiffBaseline) — the immediate win. ``` ## Plan Plan-and-execute **F11 (#43)** — preview toolbar as the primary interaction surface — per `docs/superpowers/specs/2026-06-12-f11-preview-toolbar-interaction-surface.md`. Implementation plan archived at `docs/superpowers/plans/2026-06-12-f11-preview-toolbar.md`. Posture: autonomous (yolo). Branch `f11-preview-toolbar`. Five slices (spec §7.2), each green (unit + host E2E) before the next: - **SLICE-1 — Pin baseline button + reachability** *(this session's lead — the immediate win)*: webview Pin button → `{pinBaseline}` → host `DiffViewController.pin(previewedDoc)`; unhide `cowriting.pinDiffBaseline` (`when: editorLangId == markdown`). - **SLICE-2 — Block-offset emission** (INV-36 data layer): pure `data-src-start/end` on every block, both render modes. - **SLICE-3 — Edit Document + hunk path** (INV-37 doc half): `diffToHunks`, `runEditAndPropose`, `cowriting.editDocument`. - **SLICE-4 — Adaptive Edit Selection** (INV-37 selection half): `selectionchange` label flip + selection→`data-src` resolution → single-range propose. - **SLICE-5 — Gateway, edges, tests & docs**: `editor/title` gateway, non-authorable disabling, MANUAL-SMOKE-F11.md, README. ## Session arc Pre-state: clean `main` at `b2de25f` (after a fast-forward of 2; the F11 spec had just graduated in session 0036). #43 = `type/feature` with a graduated Solution Design → eligible planning-and-executing anchor (R2/R3). 1. **Claim + setup.** Session gate → `wgl-planning-and-executing`; claimed ID **0037** (no concurrent sessions). Read the F11 spec (found at `docs/superpowers/specs/`, not `specs/`). Wrote the implementation plan (`docs/superpowers/plans/2026-06-12-f11-preview-toolbar.md`), branched `f11-preview-toolbar`. Baseline 197 unit green. 2. **SLICE-1 (commit 8b9e61a).** TDD: failing E2E (`receiveMessage` seam absent) → extracted `handleWebviewMessage`, added the `pinBaseline` intent → `DiffViewController.pin(previewedDoc)`, the Pin button, theme CSS, unhid `pinDiffBaseline`. Discovered the `undoMarks` E2E flakes (passed on re-run). 3. **SLICE-2 (1ef9451).** Pure `srcAttr` helper threaded through renderOp / renderReviewOp / renderReview; `renderPlain` switched to per-block bare divs. data-src on every live block in both modes; removed/proposal blocks carry none. 4. **SLICE-3 (0d1a563).** Pure `diffToHunks` (word-level, coalescing); host `runEditAndPropose` + injectable `editTurn`/`setEditTurnForTest`; the askClaude message + `cowriting.editDocument`; Edit Document button. 5. **SLICE-4 (03b61ed).** Webview adaptive label (`selectionchange`) + `nearestSrc`/`selectionSrcRange` block-union mapping; host range branch (already shared from SLICE-3). E2E for the selection path. 6. **SLICE-5 (1564ef5).** `editor/title` gateway; `authorable` render flag + `editControlsEnabled` seam + webview disable; `MANUAL-SMOKE-F11.md`; README. 7. **Self code review (subagent) → fixes (47cc733).** Caught a **Critical**: pure-insertion hunks were born-orphaned (verified against `anchorer.resolve`). Fixed with `anchorInsertion`; added reconstruct + accept-all E2E coverage; added `turnId`; documented the renderPlain cross-block tradeoff + a characterization test. Ran the isolation experiment proving the `undoMarks` flake is F11-independent. 8. **Ship.** Pushed; PR **#44** (Gitea API) → merged to `main` (62a2229); #43 commented + closed; branch deleted; 208 unit green on main. Cut state: on `main`, clean, fully pushed. The only red in the host E2E suite is the pre-existing `undoMarks` flake (see Deferred decisions); all 9 F11 E2E + 208 unit are green. ## Next /goal ``` /goal plan-and-execute #42 then #41 (now unblocked by F11) — expand the right-click menu sets into the preview (Ask Claude to Edit + Open Review Panel), per spec §6.7 fork 3; first capture the pre-existing undoMarks E2E flake as a follow-up bug. ``` ## Deferred decisions _Autonomous-mode low-confidence calls the driver made and would have liked operator input on. Appended as the session runs; surfaced at finalize. Empty if none._ - **Pre-existing E2E flake — PROVEN F11-independent, recommend a follow-up issue:** `undoMarks.test.ts` ("F10 #38 — undo of a deletion of baseline text leaves it unattributed") fails on `executeCommand("undo")` not reverting the `applyEdit`-applied changes. Early in the session it failed ~1/3 (passing on re-run); later in the session it failed consistently (machine-load sensitive). **Isolation experiment:** removed all F11 tests, clean rebuild → the undo test still fails identically (44 passing, same `undo restored 'bravo'` at the same line). So it is NOT caused/aggravated by F11 — F11 touches only preview message routing + the pure render layer. Tried a focus+single-undo+poll hardening; it did NOT fix this run (root cause is `undo` not reverting programmatic `WorkspaceEdit`s in test-electron, not mere timing), so I reverted it to keep the F11 PR scoped. **Recommend a dedicated follow-up issue:** redesign the undo test to not depend on `executeCommand("undo")` over `applyEdit` (e.g. drive the attribution branch directly, or type real edits). All 9 F11 E2E tests are green. - **SLICE-2 off-mode wrapping (autonomous call):** `renderPlain` now wraps each block in a bare `
` (no `cw-` class) rather than rendering the whole document in one markdown pass. This makes the off/clean preview a selection→source surface (INV-36) and matches `renderReview`'s long-standing per-block rendering. Trade-off (raised in code review): cross-block markdown constructs separated by blank lines (reference-link defs, footnotes) don't resolve in off-mode — a regression for off-mode specifically, but it makes both modes consistent (on-mode already had it). Inherent to the operator-locked block-level mapping (§6.7). Kept per INV-36 ("both modes"); documented with a docstring note + a characterization test. A cross-block-fidelity improvement (markdown-it source maps) is a possible follow-up, not a change to the locked decision. - **Code review run (self, via subagent) before merge:** found 1 Critical (pure- insertion hunks born-orphaned — could never be accepted), 2 Important (the cross-block renderPlain regression above; sequential multi-hunk accept untested), 3 Minor (no turnId; test-seam recompute; webview disable not auto-tested). Fixed the Critical (anchorInsertion + reconstruct/accept-all tests), the turnId, and added accept-all + characterization coverage; accepted/documented the cross-block tradeoff. Commit `47cc733`.
