+## 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).
