## Launch prompt

`/wgl-planning-and-executing implement #60 (live turn progress) from coauthoring-live-progress.md`

(Continuation of brainstorming session 0055, which graduated the spec; the
operator said "implement it" → this coding session.)

## Plan

Plan + execute **#60** (P1 feature — live turn progress) from the graduated
Solution Design `coauthoring-live-progress.md`. Four cuts: (1) pure
`turnProgress.ts` reducer + tests; (2) `runEditTurn` + `onProgress`/`AbortSignal`;
(3) `liveProgressUi` + setting + both call sites; (4) host-E2E + smoke.
Branch `s60-live-progress` → PR → main.

## Pre-state

- Clean `main` at session start (fast-forwarded 13 commits — the sessions/ repo
  is the code repo itself). Baseline: 222 unit green.
- #60 has a graduated Solution Design → §4.3 R2(b) satisfied.

## Session arc

1. **Claim + plan.** Claimed 0056 (no in-flight). Wrote the implementation plan
   with `superpowers:writing-plans` → `docs/superpowers/plans/2026-06-26-live-turn-progress.md`
   (self-reviewed: full spec coverage, no placeholders). Grounded in the exact SDK
   types (`AgentToolCallPart.toolName`, `AgentUsage.inputTokens+outputTokens`), the
   vitest/host-E2E patterns, and the injectable `editTurn` seam. Branch
   `s60-live-progress`.
2. **Task 1 — pure reducer.** `src/turnProgress.ts` + `test/turnProgress.test.ts`
   (13 cases). Fixed the type-only event import: `AgentRuntimeEvent` is exported
   from **`@cline/shared`**, not `@cline/sdk` (which doesn't re-export it) — caught
   by typecheck; amended the commit.
3. **Task 2 — `runEditTurn`.** Added `RunEditTurnOptions {onProgress, signal}`;
   subscribes to the agent, folds events through the reducer, wires `signal` →
   `agent.abort()`; `finally` unsubscribes. Mocked-agent unit tests (vitest
   `doMock` intercepts the dynamic import).
4. **Task 3 — host relay.** `src/liveProgressUi.ts` (notification line +
   "Cowriting: Claude" OutputChannel, reveal gated by setting) + `package.json`
   `contributes.configuration` `cowriting.liveProgress.revealOutput`.
5. **Tasks 4+5 — both call sites.** `editSelection` (extension.ts) and preview
   `askClaude`/`runEditAndPropose` (trackChangesPreview.ts) made cancellable,
   relaying via the shared `liveProgressUi`; widened the `EditTurn` seam to accept
   `opts?` (back-compat). Added `liveProgressUi` to `CowritingApi`.
6. **Task 6 — host E2E.** `test/e2e/suite/liveProgress.test.ts`: progress is
   additive (INV-44), aborted turn proposes nothing (INV-47).
7. **Task 7 — verify + smoke.** typecheck + 237 unit + build green; enhanced
   `scripts/smoke-live-turn.mjs` to log progress.
8. **Subagent review.** Found a **Medium** (a pre-aborted `AbortSignal` was a
   no-op — `agent.abort()` runs before the SDK's AbortController exists, so the
   turn ran to completion) + a **Low** (a throwing `onProgress` relay could fail
   the turn). Fixed both: short-circuit (throw) before `run()` on a pre-aborted
   signal; wrap the relay in try/catch. Strengthened the unit + E2E to prove it.
9. **Ship.** Pushed; opened PR #61; operator approved merge despite the
   concurrency (below). Squash-merged `644885c`; issue #60 auto-closed.

## ⚠️ Concurrency event (mid-session)

Partway through, the shared working tree gained **uncommitted changes this session
did NOT make** — a `cowriting.edit` / `routeEdit` reach refactor across
`src/workspacePath.ts`, `test/workspacePath.test.ts`, and the menu/`routeEdit`
parts of `package.json` + `src/extension.ts`. It broke 3 E2E (`f12Reach` ×2,
`f11Toolbar` ×1) that still expect the old `editSelection`/`editDocument` command
surface. Handling: committed **nothing** of it, discarded **nothing**; verified
#60 green in isolation by stashing it (by path, reversible) — 237 unit + both #60
E2E pass, only the documented `F10 #38` undo-sandbox flake remains — then popped
the stash to restore it. Surfaced to the operator, who chose to merge #60 (its 7
commits are isolated; the PR diff contains none of the foreign WIP).

## Cut state (at finalize)

- **#60 merged** to main (PR #61 squash `644885c`); issue #60 closed.
- **Plan archived:** `submit-plan.sh` → content repo `plans/2026-06-26-live-turn-progress.md` (`22ec57e`).
- **Foreign refactor WIP:** still uncommitted in the working tree, untouched —
  for whoever is doing it to continue/commit (it rebases onto the new main).
- **Local tree:** left on branch `s60-live-progress` (merged) DELIBERATELY — a
  `checkout main`/`pull` would have disturbed the foreign uncommitted WIP. Local
  main not synced; origin/main has #60. Operator should reconcile the local tree
  + the in-flight refactor.
- **Memory:** added `session-0056-60-live-progress-shipped.md` + index line.

## Next-session prompt

```
/wgl-planning-and-executing reconcile the local tree (sync main; land/branch the in-flight cowriting.edit/routeEdit refactor), then pick the next item (open: #59 P1 bug, #57, #58, #32, #35, #40, OQ-2)
```

## Deferred decisions

- **Left local on `s60-live-progress` (did not sync main):** to avoid disturbing
  the concurrent uncommitted refactor in the shared tree. Low confidence this is
  the tidiest end state, but it is the safest for the foreign WIP. Operator to
  reconcile.
- **Token field for the activity line:** used `inputTokens + outputTokens` from
  `AgentUsage` (no `totalTokens` field exists). Cache tokens excluded.
- **OutputChannel append-not-clear + auto-reveal gating:** per spec §3.5; carried
  from session 0055's confirmed sub-decisions.
