The one Ask-Claude toolbar button now adapts: its label flips on selectionchange
(Edit Selection when live text is selected in the preview, Edit Document
otherwise), and a click resolves the preview selection to a SOURCE range via the
nearest data-src ancestors (INV-36) — the webview's sole mapping duty. A
selection touching no live-source block falls back to document scope. Per spec
§6.5 PUC-2/3 / §7.2 SLICE-4.
- webview (media/preview.ts): nearestSrc() DOM walk + selectionSrcRange()
block-union; updateAskLabel() on selectionchange + after each render; the
adaptive click posts { askClaude, scope:"selection", start, end } or falls back
to document scope. Sealed (INV-21): reads data-src only, posts intent.
- host: runEditAndPropose's range branch (already shared from SLICE-3) records one
single-range F4 proposal over the resolved block-union.
- host E2E: stubbed selection turn → exactly one proposal over the resolved range
(turn receives exactly the selected source; replaced == the range; doc
untouched); an unchanged replacement proposes nothing. (The webview DOM
selection→data-src lookup is sealed-sandbox → manual smoke, spec §6.8.)
205 unit + 51 host E2E green.

A whole-document Ask-Claude rewrite is diffed into hunks and surfaced as N
independent F4 proposals (one per changed hunk) — reusing the F4 single-range
model N times, no new model. Per spec §6.4/§7.2 SLICE-3.
- trackChangesModel: pure `diffToHunks(currentText, rewrittenText)` →
EditHunk[] (vscode-free, deterministic; diffWordsWithSpace, coalescing
adjacent add/remove runs; offsets index currentText).
- trackChangesPreview: `runEditAndPropose(document, target, instruction)` — the
shared host routine (selection → one single-range propose; document → diff →
one propose per hunk; never mutates the doc, INV-10); `askClaude` UI wrapper
(host showInputBox keeps LLM/secrets out of the sealed webview, INV-8/35);
injectable `editTurn` + `setEditTurnForTest` seam (no LLM in CI); the
`askClaude` inbound message branch; `cowriting.editDocument` command for #42
reuse.
- package.json: register cowriting.editDocument, palette-guarded on markdown.
- webview: ✦ Ask Claude to Edit Document button → { askClaude, scope:"document" }.
- unit: diffToHunks fixtures (zero/one/multi-hunk, wholesale, determinism).
- host E2E: stubbed multi-hunk rewrite → N matching proposals, doc untouched;
editDocument command registered + markdown-guarded.
205 unit + 49 host E2E green.

Homes the orphaned cowriting.pinDiffBaseline command and gives the writer a
reachable Pin control in the preview toolbar. Per spec §7.2 SLICE-1
(docs/superpowers/specs/2026-06-12-f11-preview-toolbar-interaction-surface.md).
- trackChangesPreview: extract onDidReceiveMessage into handleWebviewMessage;
add the F11 `pinBaseline` intent → DiffViewController.pin(previewedDoc) (the
bound doc, not activeTextEditor — §6.7); ToolbarMsg union; receiveMessage test
seam exercising the real message→seam wiring (INV-35).
- webview: ⌖ Pin baseline button in #cw-header posting { type: "pinBaseline" };
theme-aware toolbar-button CSS (light/dark/high-contrast, disabled state).
- package.json: unhide pinDiffBaseline — commandPalette `when` false →
editorLangId == markdown (resolves the #34 orphan from the command side).
- host E2E (test/e2e/suite/f11Toolbar.test.ts): pinBaseline message clears the
change-marks + advances the baseline to `pinned`; palette `when` is reachable.
Also archives the F11 implementation plan to docs/superpowers/plans/.
197 unit + 47 host E2E green.
