`tsc -p tsconfig.e2e.json` emits to `out/` but never removes outputs for test
sources absent on the current branch, so stale compiled
`out/test/e2e/suite/*.test.js` from other branches were picked up and run by the
suite glob (`**/*.test.js`) — this caused real cross-branch test confusion in
session 0048 (a deleted probe + another branch's tests ran on an unrelated branch).

Add a `clean:e2e` script (`fs.rmSync('out/test', {recursive, force})` via node, so
no shell `rm` dependency) and run it between `build` and `tsc` in `pretest:e2e`.
Cleans ONLY `out/test` — never `out/`, which holds the just-built esbuild bundle
(`out/extension.cjs`, `out/media`).

Verified: planting a stale `out/test/.../zz.test.js` then running `pretest:e2e`
removes it, and the E2E suite stays green (73 passing + 1 pending, both passes
exit 0).

+/goal plan-and-execute #40 (restore exact author attribution on undo/redo — follow-up to #38)
+
+```
+
+## Plan
+
+**#40 (task, P3)** — restore exact author attribution on undo/redo (follow-up to
+#38). Anchor: leaf `task` → §4.3 R2 (no design gate). Picked autonomously (last
+R2-eligible leaf not blocked by a content-repo/careful/irreversible gate).
+
+#38 made undo/redo re-inserted text **neutral** (no false human coloring) but
+lossy: undoing a deletion of Claude text shows it neutral, not blue. #40 restores
+the **exact prior** attribution.
+
+**Mechanism (engineering choice): text-keyed attribution snapshots.** Per-doc
+`Map<documentText, spans>`; snapshot after every FORWARD edit (and at load). On
+undo/redo, after the #38 geometry reconcile, if a snapshot's text equals the
+current buffer, restore those spans exactly (offsets valid — text identical).
+Robust to VS Code undo coalescing (only the event whose resulting text matches a
+snapshot restores; far-back/evicted states fall back to #38 neutral). Bounded
+history.
+
+Tasks: snapshot+restore in `attributionController` (loadAll + onDidChange);
+tests (agent-text undo restores blue; edit→undo→redo round-trip; #38 regression
+green). No deploy pipeline (extension).
+
+## Results
+
+**#40 implemented but NOT shipped — verification-blocked.** On branch
+`s40-undo-provenance` (pushed, unmerged); issue #40 **kept open**.
+
+- `attributionController.ts` — text-keyed attribution snapshots
+  (`attrHistory: Map<documentText, spans>`, `ATTR_HISTORY_MAX` bounded): snapshot
+  after every forward edit + at `loadAll`; on undo/redo restore the snapshot whose
+  text equals the current buffer (else #38 neutral fallback). Robust to undo
+  coalescing.
+- `test/e2e/suite/s40Provenance.test.ts` — agent-text-undo-restores-blue +
+  edit→undo→redo round-trip.
+- **222 unit + typecheck green.**
+
+**BLOCKER (environmental, not the code):** the #40 host E2E — and the *untouched*
+#38 `undoMarks` E2E — drive `executeCommand("undo")`, which does **not restore
+text** in this local test instance. Proven by stashing all my changes and running
+clean `main`: the #38 test fails identically (`undo restored 'bravo'`). This is the
+**known undoMarks flake (session 0037), now deterministic** in this environment.
+The usual remedy — clearing `.vscode-test/user-data` — is **permission-blocked**
+this session (`rm -rf` denied). Focusing the doc before `undo` (`showTextDocument`)
+did not help. So #40's end-to-end behavior cannot be verified here; shipping
+unverified changes to the load-bearing F3 attribution controller would violate
+verify-before-completion. Left on a branch for the operator to verify + merge in a
+working E2E environment.
+
+**Also surfaced:** `main`'s E2E is currently **red in this environment** for the
+same environmental reason (the undoMarks `undo` flake) — a test-infra issue
+independent of product code.
+
+## Session arc
+
+1. Stop hook required determining/executing the next milestone; chose #40 (last
+   R2-eligible leaf). Claimed 0048, clean `main`.
+2. Read #40 + #38 + the attribution change handler; chose text-keyed snapshots.
+3. TDD: wrote #40 E2E + implemented snapshot/restore; 222 unit green.
+4. E2E: 3 undo-driven tests failed at the `undo restored X` step. Isolated by
+   stashing → clean `main`'s #38 test fails identically → environmental undo flake,
+   not my code. Could not clear `.vscode-test` (permission-blocked).
+5. Committed #40 to a branch (pushed, unmerged, marked UNVERIFIED); kept #40 open;
+   stopped per verify-before-completion.
+
+## Deferred decisions
+
+_Autonomous-mode low-confidence calls the driver made and would have
+liked operator input on. Empty if none._
+
+- **Did not merge #40** (driver call). Alternative: merge on unit-green + reasoning
+  alone. Why not: it changes the core F3 attribution controller and its behavior is
+  only meaningfully provable through an undo E2E, which is environmentally broken
+  here — verify-before-completion says don't claim/ship it. Preserved on a branch
+  for operator verification instead. (Reversible: just merge once verified.)

+```
+/goal plan-and-execute: pretest:e2e cleans stale compiled tests in out/test (stale *.test.js from other branches were running via the glob) — build hygiene follow-up to #54
+
+```
+
+## Plan
+
+Build-hygiene follow-up to #54 (noted on that issue). `tsc -p tsconfig.e2e.json`
+emits to `out/` but never removes outputs for test sources absent on the current
+branch, so stale compiled `out/test/e2e/suite/*.test.js` from other branches get
+run by the suite glob (`**/*.test.js`) — this caused real cross-branch test
+confusion in session 0048 (a removed probe + the s40 branch's tests ran on an
+unrelated branch). Fix: `pretest:e2e` cleans `out/test` before recompiling.
+
+- `package.json` — add `clean:e2e` (node `fs.rmSync('out/test', {recursive,force})`
+  — avoids shell `rm` issues) and run it between `build` and `tsc` in `pretest:e2e`.
+  Clean ONLY `out/test` (NOT `out/`, which holds the just-built esbuild bundle).
+- Verify: introduce a stale `out/test/.../zz.test.js`, run `pretest:e2e`, confirm
+  it's gone + the E2E suite is green.
+
+Trivial, ungated, verifiable; test-infra only. No deploy pipeline (extension).
+
+## Results
+
+**Shipped to `main`** — PR #56 (merged). `package.json`: new `clean:e2e`
+(`fs.rmSync('out/test',{recursive,force})`) run between `build` and `tsc` in
+`pretest:e2e`. Cleans only `out/test` (never the esbuild bundle in `out/`).
+Verified: a planted stale `out/test/.../zz.test.js` is removed by `pretest:e2e`;
+E2E green (73 passing + 1 pending [#38 undo-skip], both passes exit 0). Test-infra
+only; no product code.
+
+Properly tracked under this session (0049) — closing the protocol gap where
+#54/#55 merged after 0048 had finalized.
+
+## Session arc
+
+1. Stop hook pushed me to execute the one remaining ungated/verifiable item (the
+   `out/`-clean follow-up I'd noted on #54). Claimed 0049 to track it cleanly.
+2. Confirmed `tsc` outDir → `out/test`; esbuild bundle → `out/extension.cjs`
+   (separate), so cleaning `out/test` is safe.
+3. Implemented `clean:e2e`; verified by planting a stale compiled test (removed)
+   + full E2E green. Shipped PR #56.
+
+## Deferred decisions
+
+_Autonomous-mode low-confidence calls the driver made and would have
+liked operator input on. Empty if none._
+
+- _No low-confidence calls this session._ (Cleaning stale build output is
+  unambiguously correct; scoped to `out/test` to protect the esbuild bundle.)

+## Launch prompt
+
+`/wgl-capture` — "When changing documents, we should decide what happens to the
+review pane of the current document, and if the document switched to should get a
+review experience or not"
+
+## Pre-state
+
+- Branch `main`, clean, pushed (origin/main). No in-flight sessions for the app.
+- Tracker `benstull/vscode-cowriting-plugin` (host `git.benstull.org`); content
+  repo `vscode-cowriting-plugin-content` cloned, with ~18 prior uncommitted
+  capture drafts in `issues/`.
+- Prior frontier exhausted (session 0047 note): remaining backlog items gated;
+  operator directing. This is a capture session, not a build.
+
+## Arc
+
+1. **Claimed** tracked-lite session ID **0050** (`claim-session-id.sh --type
+   capture`). Resolved app + content repo (`resolve-app.py`).
+2. **Grounded** the ask by reading the code (Explore subagent over
+   `src/trackChangesPreview.ts`, `diffViewController.ts`, `proposalController.ts`):
+   confirmed the review pane is one-panel-per-doc keyed by URI
+   (`trackChangesPreview.ts:45`) with **no** `onDidChangeActiveTextEditor`
+   listener — so on document switch the pane **stays pinned** to its original doc
+   (incidental, not designed) and the switched-to doc gets no review until
+   `showTrackChangesPreview` is re-invoked. Per-doc review state (F6 baseline / F4
+   proposals / F3 attribution) auto-creates on demand.
+3. **Sized** the single ask: genuine forks (follow / pin / close; auto-review /
+   on-demand) + needs design before build → `type/feature` (R3), `priority/P2`.
+   Captures the decision-to-be-made; option space goes in Solution notes,
+   non-binding.
+4. **Drafted** `issues/review-pane-on-document-switch.md` in the content repo
+   (working tree only, INV-8), full §5 template. Scanned clean for secrets
+   (INV-3).
+5. **Operator approved** filing as-is (feature, P2) via AskUserQuestion.
+6. **Filed** → ensured labels (all pre-existing), then `capture-issues.sh` →
+   **#57** (https://git.benstull.org/benstull/vscode-cowriting-plugin/issues/57).
+
+## Cut state
+
+- Session repo `vscode-cowriting-plugin`: clean `main`, nothing committed this
+  session (capture touches only the content repo working tree). No PRs.
+- Content repo: new draft `issues/review-pane-on-document-switch.md` left
+  uncommitted for the Author to publish/discard (INV-8), alongside the prior
+  drafts already there. Not pushed by this skill.
+- Issue **#57** filed and open on the tracker.
+
+## Deferred decisions
+
+_None — single clear ask, operator approved the framing and type before filing._
+
+## Operator plate
+
+- One feature filed: **#57** (review-pane behavior on document switch, P2).
+- ~19 capture drafts now sit uncommitted in `vscode-cowriting-plugin-content` —
+  yours to commit/publish (or discard) when convenient.
+- #57 needs a design before build (R3). No active plan frontier; operator to
+  direct next.
+
+## Next session prompt
+
+`/goal` — operator to direct. Candidate: brainstorm a Solution Design for **#57**
+(review-pane behavior on document switch) — settle the two coupled rules (outgoing
+pane fate; whether the switched-to doc auto-gets a review experience) before
+building. Other open: OQ-2 (F11 graduation), #32 (scroll-sync, needs design),
+#35 (repo rename), #40 (undo provenance, P3, branch `s40-undo-provenance`
+unmerged), #54 (undo still broken in sandbox).

+
+## Launch prompt
+
+`/wgl-capture` — two asks:
+1. "Undo doesn't undo Claude's edits"
+2. "When I make a change within a block that Claude has changed that I haven't
+   approved, it doesn't show my changes"
+
+## Pre-state
+
+- Branch `main`, clean, pushed. Immediately followed capture session 0050 (#57).
+- Tracker `benstull/vscode-cowriting-plugin` (host `git.benstull.org`); content
+  repo cloned.
+
+## Arc
+
+1. **Claimed** tracked-lite session ID **0051**.
+2. **Grounded** both asks in code (Explore subagent):
+   - Undo: Claude's edits are pending proposals; `proposalController.ts:303-310`
+     shifts anchors on edit but ignores `e.reason === Undo` — proposal not
+     reconciled on undo (accepted edits hit the doc and are undoable, but the
+     pending proposal lingers).
+   - Pending-block edits: a proposal freezes its "before" (`replaced: fp.text`,
+     `proposalController.ts:81-95`); the block renders from current text but the
+     proposal's frozen view (`trackChangesModel.ts:706-722`/`:769-805`) obscures
+     live human edits in that block.
+3. **Checked duplication** against the undo cluster — #38 (wrong marks, closed),
+   #40 (attribution color, open), #54 (undo E2E infra, open). Both new asks are
+   distinct (undo failing to *reverse* the edit; live edits obscured by a pending
+   proposal). Verified `type/bug` exists on the tracker.
+4. **Drafted** both as `type/bug` (P1) in the content repo working tree
+   (`issues/undo-does-not-undo-claude-edits.md`,
+   `issues/edits-in-pending-block-not-shown.md`), each framed as user-facing pain
+   with repro steps + code diagnosis demoted to parenthetical. Scanned clean for
+   secrets (INV-3).
+5. **Operator triage:** before filing, operator said "ignore both of these
+   issues — you can delete the drafts." Both drafts **deleted**; nothing filed.
+
+## Cut state
+
+- **Nothing filed** (INV-4 — no-actionable outcome after operator triage).
+- Both draft files removed from the content repo working tree.
+- Session repo `vscode-cowriting-plugin`: clean `main`, no commits this session.
+
+## Deferred decisions
+
+_None — operator explicitly directed dropping both asks._
+
+## Operator plate
+
+- No issues filed this session. The two undo/pending-block asks were
+  considered and intentionally dropped (recorded in memory
+  `session-0051-capture-no-actionable.md` so they aren't re-raised as new).
+- Note: these remain *real* observed behaviors per the code reading — dropped on
+  operator triage, not because they were invalid. If they resurface, the prior
+  grounding is in the memory note.
+

+
+**Ask 1 — scroll-sync (duplicate, nothing filed):**
+1. Claimed tracked-lite session ID **0052**.
+2. Recognized scroll-sync as a known F10 follow-up; fetched **#32** — exact match
+   (*"Scroll-sync the review preview with the source editor"*, open,

+3. Surfaced to operator; operator chose to **leave #32 at P3**. No new issue
+   (INV-4 duplicate).
+
+**Ask 2 — proposal block diff vs original (filed #58):**
+4. Grounded in code (Explore): the pending proposal block renders original +
+   proposed as **two separate full blocks** (`<del>` whole-before + `<ins>`
+   whole-after, `trackChangesModel.ts:715-716`) with **no word-level diff** — the
+   changed-block rendering already uses `wordMergedMarkdown`/`diffWords`
+   (`trackChangesModel.ts:431-438`) but `proposalBlockHtml()` doesn't.
+   `ProposalView` already carries `replaced`+`replacement`

+1. Claimed tracked-lite session ID **0053**.

+   `trackChangesPreview.ts:232-233`) awaiting `agent.run()` as one black-box
+   promise (`liveTurn.ts:52`). Key enabler: `@cline/sdk` already emits streaming
+   events (`assistant-text-delta`, `tool-started/updated/finished`,
+   `usage-updated`) via `agent.subscribe()` / an `onEvent` hook, but the extension
+   constructs the Agent with **no hooks** (`liveTurn.ts:47-51`) and discards it.
+3. **Sized** `type/feature` — implementable by subscribing to existing events, but
+   a real design fork on the surface (notification text vs. OutputChannel vs.
+   status bar vs. webview relay) and content (text/tool/usage/reasoning) → design
+   first (R3). Drafted `issues/show-live-claude-progress.md` (working tree only,
+   secrets scanned).
+4. **Operator set priority** — chose "adjust priority" → **P1** (opaque wait hurts
+   every turn). Updated WSJF line.
+5. **Filed #60** (`type/feature`, P1).
+   → https://git.benstull.org/benstull/vscode-cowriting-plugin/issues/60
+
+## Cut state
+
+- **#60** filed (feature, P1).
+- Draft `issues/show-live-claude-progress.md` left uncommitted in the content repo
+  for the Author to publish (INV-8).
+- Session repo `vscode-cowriting-plugin`: clean `main`, no commits this session.
+
+## Deferred decisions
+
+_None — operator set the priority directly and approved the framing._
+
+## Operator plate
+
+- One issue filed: **#60** (live Claude progress, feature, **P1**).
+- Implementation is largely "subscribe to SDK events already available + pick the
+  progress surface" — needs a small design first (R3).
+- One uncommitted capture draft added to the content repo — yours to publish or
+  discard.
+
+## Next session prompt
+
+`/goal` — operator to direct. Capture run 0050–0054 filed #57, #58, #59, #60
+(scroll-sync = existing #32). Two P1s now open (**#59** automation prompt,
+**#60** live progress) plus standing #57 (review-pane on doc switch, design
+candidate). Other open: #58 (proposal word-diff, P2), #32 (scroll-sync P3), OQ-2
+(F11 graduation), #35 (repo rename), #40 (undo provenance P3), #54 (undo E2E
+infra).

+
+> App: vscode-cowriting-plugin
+> Start: 2026-06-22T23-19 (PST)
+> End: 2026-06-26T04-23 (PST)
+> Type: brainstorming
+> Posture: autonomous (yolo)
+> Status: **FINALIZED**
+
+## Launch prompt
+
+`/wgl-brainstorming highest priority ticket`
+
+## Plan
+
+Brainstorming session: explore the highest-priority open ticket and write its
+Solution-Design spec. Highest-priority that fits a brainstorming session (spec
+output; a feature needs a design per §4.3 R3) was **#60 — Show Claude's live
+output/progress during the "asking Claude…" status** (P1 feature). #59 (P1 bug)
+is coding-session work, not brainstorming.
+
+Output: `specs/coauthoring-live-progress.md` (Solution Design), submitted graduated
+at finalize to the content repo's `specs/` collection.
+
+## Pre-state
+
+- Clean, pushed `main` (`24e329e`). No in-flight sessions (next ID 0055).
+- Two P1 tickets tied for highest priority: **#59** (P1 bug — spurious macOS
+  "control other applications" prompt) and **#60** (P1 feature — live turn
+  progress). Brainstorming produces a spec; a feature needs a design (§4.3 R3),
+  so #60 was the fit. #59 (bug) → a coding session.
+- Highest INV in use across the content-repo specs: **INV-42**.
+
+## Session arc (turn-by-turn)
+
+1. **Gate + classify.** Launch prompt classified as **brainstorming**; ran
+   `wgl-brainstorming`.
+2. **Claim (peek → gate → claim).** `claim-session-id.sh --dry-run` → no in-flight
+   sessions, next ID **0055**. Claimed `--type brainstorming` (placeholder at
+   `16cca30`). Verified clean pushed `main` baseline.
+3. **Orient.** Surveyed the open tracker. Picked **#60** (P1 feature, design
+   needed) over #59 (P1 bug, coding-session work). Read #60 in full.
+4. **Ground in code (read-only).** Read `liveTurn.ts` (`runEditTurn` →
+   `agent.run()` as one opaque promise; module is deliberately vscode-free), both
+   call sites (`extension.ts:232` editSelection, `trackChangesPreview.ts:232`
+   preview `askClaude` — both wrap the turn in `withProgress("asking Claude…")`),
+   the injectable `editTurn` seam (trackChangesPreview.ts:56, for host-E2E
+   stubbing), and the `@cline/sdk` event API: `@cline/agents` `Agent` exposes
+   `subscribe(listener) → unsubscribe`, `run()`, `abort()`; `AgentRuntimeEvent`
+   (in `@cline/shared/dist/agent.d.ts`) carries `assistant-text-delta`
+   (+`accumulatedText`), `tool-started|updated|finished`, `usage-updated`,
+   lifecycle events. The enabler the issue cites is real.
+5. **Brainstorm forks (superpowers:brainstorming).** Skipped the visual companion
+   (choices are conceptual/native-UI, not visual mockups). Presented three forks
+   via AskUserQuestion; operator picked all three recommendations:
+   - **Surface** → notification activity-line + token count **and** a shared
+     `"Cowriting"` OutputChannel streaming full assistant text. (Rejected: webview
+     relay can't cover the editSelection path; status-bar-only; OutputChannel-
+     primary.)
+   - **Content** → activity + token count (reasoning text not surfaced).
+   - **Cancellation** → `cancellable` notification → `agent.abort()` →
+     "cancelled", proposes nothing (reflect + cancel button).
+6. **Design presented + approved.** Three-unit architecture (pure
+   `turnProgress.ts` reducer → `runEditTurn` extended with `onProgress` +
+   `AbortSignal` → both call sites relay via a shared `liveProgressUi`); layering
+   rule keeps `liveTurn.ts`/`turnProgress.ts` vscode-free; INV-43..47. Two
+   sub-decisions (OutputChannel auto-reveal gated by a new setting; append-not-
+   clear) confirmed. Operator: "design looks right."
+7. **Spec written + self-review.** `specs/coauthoring-live-progress.md` authored
+   in house Solution-Design format. Self-review: no placeholders, INV-43..47 (no
+   collision with ≤42; INV-8/21/39 are correct citations), internally consistent,
+   single-feature scope.
+8. **Operator: "Implement it."** Per the pipeline, that's the brainstorm→coding
+   handoff (one SPEC = one plan = one execution, §4.3). Finalized this
+   brainstorming session (below); a fresh `wgl-planning-and-executing` session
+   plans + builds #60.
+
+## Cut state (at finalize)
+
+- **Spec graduated.** `submit-spec.sh --status graduated` →
+  `vscode-cowriting-plugin-content` `specs/coauthoring-live-progress.md` at
+  `3bd1ae5`.
+- **Code repo:** clean `main`; no code changes this session (brainstorming).
+  A local stray `specs/coauthoring-live-progress.md` remains untracked in the code
+  repo (an `rm` cleanup was permission-denied; harmless — canonical copy is in the
+  content repo).
+- **Memory:** added `session-0055-live-progress-spec-graduated.md` + index line.
+
+## Next-session prompt
+
+```
+/wgl-planning-and-executing implement #60 (live turn progress) from coauthoring-live-progress.md
+```
+
+## Deferred decisions
+
+- **OutputChannel auto-reveal** (fires every Claude turn): decided to auto-`show(true)`
+  (preserveFocus) on the *first* text delta, gated by a new setting
+  `cowriting.liveProgress.revealOutput` (default `true`). Operator confirmed the
+  design including this.
+- **OutputChannel history:** decided to *append* per-turn (with a header) rather
+  than clear, so it doubles as a debug log. Operator confirmed.
+- **Stray local spec file:** `rm -rf specs/` was permission-denied; left the
+  untracked local copy in the code repo (cosmetic; content repo holds the
+  canonical copy).
