+# Task: Fix running conversation abort stall
+
+## Identity
+
+- Task ID: 20260901-conversation-abort-stall-6f4c2a91
+- Mode: Feature
+- Branch: codex/20260901-conversation-abort-stall-6f4c2a91-conversation-abort-stall
+- Worktree: D:\Datas\OthersProjects\makelore-conversation-abort-stall-6f4c2a91
+- Base commit: 143aaec3d6770dd263bf1e418e89bf722989caef
+- Owner: codex-root
+- Status: Completed
+
+## Scope
+
+- Diagnose the installed 1.2.1 state where a Conversation continued to render as running and neither visible abort entry point unlocked the UI.
+- Correlate the screenshot with privacy-safe Main lifecycle and Pi Session metadata, then reproduce the stale-Renderer state at the public Chat seam.
+- Make both the Header and Composer abort actions reconcile the authoritative Conversation Snapshot after the abort request completes.
+- Add focused Renderer regression coverage and extend the existing Electron E2E fixture for a missed terminal SSE patch.
+
+## Intent And Constraints
+
+- Preserve ADR-006: Pi `0.84.2` remains the sole production runtime and Electron Main remains the only Pi/Host API authority.
+- Do not replay accepted or uncertain work, change the abort RPC/Host API contract, add polling, or introduce a fallback/compatibility path.
+- Treat the visible running state as evidence to investigate, not proof that the bash subprocess or Pi turn is still active.
+- Keep the change at the existing Renderer Host API boundary and use the existing target-only Snapshot recovery semantics.
+- Work only in the isolated feature worktree; do not modify the occupied `main` worktree or the completed 1.2.1 packaging task.
+
+## Outcome
+
+- Confirmed the screenshot was from installed Makelore 1.2.1. The affected Pi JSONL Session recorded three bash tool results and a final assistant `stop` by 14:55:35, while the 14:59 screenshot still rendered the earlier bash call as executing. Main later stopped the already-idle logical thread through background sleep, so the supported incident was stale Renderer state rather than an indefinitely running curl process.
+- Reproduced the defect with a focused Chat test: the UI held a running Snapshot, the abort request succeeded against an already-terminal authority, but `getCodingConversationSnapshot` remained at one call and the UI stayed on `中止生成`.
+- Added one shared `abortConversation` path in `CodingChatPanel`: after the existing POST abort completes, it silently reloads that Conversation's authoritative Snapshot. Both the Header `中止` button and Composer `中止生成` button now use this path.
+- Kept error ownership in the existing controls: Header action failures remain local to Header, while Composer failures remain scoped to the originating draft/Conversation.
+- Updated the Electron E2E host fixture so a deliberately missed terminal SSE patch becomes an authoritative aborted Snapshot only after the user clicks abort; the test now proves both abort controls disappear and runtime settings unlock after reconciliation.
+
+## Verification
+
+- Red regression before the fix: `tests/unit/coding-chat-panel.test.tsx` failed because the Snapshot API was called once instead of twice after abort.
+- `pnpm exec vitest run tests/unit/coding-chat-panel.test.tsx tests/unit/coding-feature-ui.test.tsx tests/unit/coding-conversations-facade.test.ts tests/unit/pi-conversation-runtime.test.ts tests/unit/pi-worker-pool-process-integration.test.ts` passed: 5 files, 35 tests.
+- `pnpm run typecheck` passed.
+- Scoped ESLint over the two product files and three changed test files passed with no findings.
+- `pnpm run build:vite` passed for Renderer, Electron Main, Preload, and release utility bundles; only existing bundle-size/dynamic-import warnings were reported.
+- `pnpm exec playwright test tests/e2e/pi-coding-first-chat.spec.ts --grep "PI feature UI"` passed: 1/1 Electron E2E.
+- `pnpm test` passed: 215 files / 1780 tests, 2 skipped, plus the isolated pressure test 1/1.
+- `pnpm run lint:check` completed with 0 errors and 5 existing warnings in `src/pages/Home/index.tsx` and `src/pages/Makelore/index.tsx`; no warning is in a changed file.
+- `git diff --check` passed.
+
+## Follow-ups
+
+- A new Windows installer must be built and installed before claiming the user's installed app contains this fix. Do not overwrite or relabel the already-built 1.2.1 artifact with changed source under the same version.
+
+## Promotion Candidates
+
+- None. This fix enforces the existing abort/terminal convergence and Snapshot recovery contracts without changing architecture or product direction.
