+# Task: Implement PI-150 packaging, E2E, and performance proof
+
+## Identity
+
+- Task ID: 20260824-pi-release-proof-3e725ac7
+- Mode: Feature
+- Branch: codex/20260824-pi-release-proof-3e725ac7-pi-release-proof
+- Worktree: D:\Datas\OthersProjects\makelore-pi-release-proof-3e725ac7
+- Base commit: 977445ba450f4ad32b6e6db2caf048517513ab39
+- Owner: codex-root
+- Status: In Progress
+
+## Scope
+
+- Implement and verify `PI-150 — Packaging, E2E, and performance release proof`
+  from cumulative PI-140 delivery base `977445b`.
+- Own final Pi production-closure staging, electron-builder wiring, artifact
+  verification, actual packaged Pi/provider-shaped smoke, Coding Electron E2E,
+  performance evidence, release note/runbook draft, and README current-state
+  updates.
+- Produce Windows x64 and Linux x64 final-product artifact evidence available
+  from this host. Keep canonical `.project-docs` updates for PI-160 Integration
+  Gate; this feature record contains the task-scoped evidence and promotion
+  candidates.
+
+## Intent And Constraints
+
+- Preserve Main-owned runtime/provider/credential boundaries, the exact pinned
+  Pi package and pnpm versions, Makelore app identity, project-scoped state, and
+  the single light product system.
+- Final artifact checks must prove Pi version/engine/entry/resources/production
+  closure/`get_state`, extension and skill presence, no OpenCode production
+  residue, and no development-machine absolute path.
+- `smoke:pi:real` means the actual Pi process seam from the final artifact using
+  controlled loopback/provider-shaped endpoints. Real external Provider
+  Accounts and real-provider two-worker turns are explicitly waived accepted
+  risks, never Pass; every substitute report retains
+  `realTurnVerified=false`.
+- The user explicitly skipped macOS validation. Do not manufacture or reuse
+  static/cross-platform evidence for macOS x64 or arm64. Their missing final
+  artifact, closure/native/resource, loopback, and performance evidence remains
+  an explicit release blocker, so this task cannot claim cross-platform
+  release-ready or PI-150 Done.
+- The canonical project memory at this base is stale and still describes
+  OpenCode. Treat the planner-owned PI Spec/ticket and current source as the
+  task authority; do not edit canonical memory in this feature worktree.
+- The main worktree is occupied by an older integration task. Remain rooted in
+  this isolated worktree and do not inspect or modify peer uncommitted files.
+
+## Plan
+
+1. Audit the cumulative PI-140 tree against every PI-150 packaging, smoke,
+   E2E, performance, release-note, and README requirement; reuse only verified
+   existing seams and identify concrete missing behavior.
+2. Implement focused missing harnesses/wiring/tests with behavior-level
+   regression coverage, then run typecheck and relevant unit tests.
+3. Run the full pinned validation set and build the Windows x64 final product
+   artifact; run its verifier, actual packaged Pi/provider-shaped smoke, and
+   required performance scenarios with structured statistics.
+4. Use WSL2 only if available to perform a frozen Linux x64 install, final
+   product build, verifier/smoke, and performance run; label any environment or
+   artifact limitation precisely.
+5. Record reproducible commands/results, accepted Provider risk, skipped macOS
+   release blocker, release note/runbook, README delta, and PI-160 promotion
+   candidates; complete the Task Documentation Gate without overstating
+   release readiness.
+
+## Outcome
+
+- Implementation is complete enough for final-product qualification: the tree
+  now contains a final-product Pi artifact verifier, packaged Pi/provider-shaped
+  smoke, Spec 17.3 performance runner, expanded Electron E2E, release runbook,
+  and synchronized README current-state language.
+- Final artifact execution and cross-platform evidence are still in progress.
+  PI-150 remains blocked from `Done` by the explicitly skipped macOS x64/arm64
+  validation, regardless of Windows/Linux results.
+
+## Verification
+
+- `pnpm install --frozen-lockfile` with pnpm `10.33.4`: passed; 997 packages,
+  lockfile unchanged.
+- Focused Pi verifier/performance/docs/runtime tests: 6 files passed, 14 tests
+  passed, 2 skipped.
+- `pnpm run typecheck`: passed after implementation and release-doc updates.
+- Scoped ESLint for every changed script/test: passed.
+- `pnpm run build:vite`: passed after the implementation changes.
+- `pnpm exec playwright test tests/e2e/pi-coding-first-chat.spec.ts
+  --workers=1`: passed, 2/2. The first run correctly exposed that complete tool
+  cards require user expansion and that the fixture used invalid worker status
+  `failed`; the final test follows the real expansion path and uses contract
+  status `error`.
+- `pnpm run lint:check`: passed with 0 errors and 5 pre-existing warnings.
+- `pnpm test`: passed; 178 files, 1504 tests passed, 2 skipped.
+- Full Electron E2E after the production build: passed, 24/24. An earlier
+  attempt hit one Canvas hover timing failure, and the next attempt had a
+  Windows Playwright worker exit with code `3221226505`; both isolated paths
+  passed and the final uninterrupted full run passed.
+- Final-product artifact verification is pending.
+
+## Follow-ups
+
+- Build and qualify Windows x64 and Linux x64 final product artifacts.
+- Keep missing macOS x64/arm64 evidence as a release blocker; do not promote a
+  cross-platform release-ready conclusion.
+
+## Promotion Candidates
+
+- PI-160 should promote the current Pi runtime/Conversation state from README
+  and `docs/pi-runtime-release-runbook.md` into canonical project memory after
+  integration review.
+- PI-160 should record QG-004/QG-005 as `Explicitly Waived / Accepted Risk`,
+  with `realTurnVerified=false`; this is not a Pass.
+- PI-160 must preserve the macOS x64/arm64 missing-evidence blocker unless a
+  later task supplies independent final-product evidence.

+# Pi Runtime 发布与回滚
+
+本文定义 Makelore Code 当前 Pi Runtime 正式包的发布门槛、兼容边界和整版本回滚方式。它是发布操作契约，不是历史证据归档；每次执行产生的 JSON、日志、安装包和性能报告都保存在忽略的 `release/` 目录或外部发布系统中。
+
+## 发布边界
+
+- 正式包固定使用仓库锁定的 Pi 版本和生产依赖闭包。Electron Main 从安装目录中的 `resources/pi-runtime` 解析运行时、扩展、Manifest 与编码 Skills；缺失、版本漂移、开发路径泄漏或 OpenCode 命名资源残留均阻断发布。
+- Renderer 只使用 Main-owned Host API 和产品 Conversation 契约，不读取 Pi wire 类型，也不直接启动 worker、访问本地运行时地址或接触 Provider 凭证。
+- 产品保留既有 `niancode` 应用 id、协议、数据目录和项目配置兼容标识；这不代表旧 OpenCode 运行时、路由或资源仍被携带。
+- 正式产品界面不提供 share/unshare、revert/unrevert、todos 或全局运行时控制。项目分支只创建新的 Conversation 历史，不表示文件回滚。
+
+## Conversation 兼容性
+
+升级前已有的 OpenCode Conversation 数据继续保留，项目首次进入 Pi 会显示一次迁移说明，但 Pi 不导入、续写或改写这些旧 Conversation。升级后新建的 Pi Conversation 使用新的本地契约；旧版本不能读取或续写它们。
+
+因此，旧 Conversation 的“保留”是可回滚的数据边界，不是跨运行时续写兼容。不得通过复制 Session、混用资源目录或在同一安装中切换旧/新 runtime 来绕过该边界。
+
+## 必须验证的正式产物
+
+发布候选必须分别提供以下最终产品证据：
+
+| 目标 | 最终产物 | 必须结果 |
+| --- | --- | --- |
+| Windows x64 | 安装器与 `win-unpacked` | 产物验证、Pi smoke、性能报告均 Pass |
+| Linux x64 | 发布包与 `linux-unpacked` | 产物验证、Pi smoke、性能报告均 Pass |
+| macOS x64 | 对应架构应用包 | 独立产物验证与 Pi smoke Pass |
+| macOS arm64 | 对应架构应用包 | 独立产物验证与 Pi smoke Pass |
+
+缺少任一目标的独立证据时，结论只能是 `Blocked`，不能用其他平台、staging 目录、源码测试或用户豁免替代跨平台发布就绪结论。
+
+每个平台在完成打包后，从该平台的最终应用可执行文件运行：
+
+```bash
+pnpm run verify:artifact:pi -- --app-exe <final-product-executable> --samples 5 --report <artifact-report.json>
+pnpm run smoke:pi:real -- --app-exe <final-product-executable> --samples 5 --report <smoke-report.json>
+pnpm run perf:pi:release -- --app-exe <final-product-executable> --samples 5 --report <performance-report.json>
+```
+
+产物验证必须确认版本与 Node engine、生产依赖闭包、扩展、Manifest、编码 Skills、`resolve/get_state`、无 OpenCode 资源以及无构建工作区绝对路径。Smoke 必须从最终产品可执行文件启动最终 `resources/pi-runtime`，覆盖 session、prompt、tool、abort、settle、reopen、双 worker 重叠与隔离、子 Agent 和 shutdown。性能报告必须记录 p50/p95/max/样本数组、RSS、Main→Renderer IPC/提交延迟和 Git commit，并覆盖 Spec 17.3 的十个场景。
+
+## Provider 验证的准确含义
+
+`smoke:pi:real` 中的 `real` 指真实最终 Pi 进程与最终产品资源，不指真实外部 Provider。受控 Provider-shaped 回环服务只证明 Makelore/Pi 的协议与隔离路径按预期运行。
+
+如果发布决定明确豁免真实 Provider 验证，报告必须保持 `realTurnVerified=false`，并把 QG-004/QG-005 标为 `Explicitly Waived / Accepted Risk`，不得写成 Pass。被接受的剩余风险包括真实 Provider 的协议差异、限流与并发策略、凭证隔离，以及多模态输入的供应商特定行为；报告和日志不得包含真实凭证。
+
+## 发布判定
+
+只有下列条件同时成立才能发布：
+
+1. 固定 pnpm 版本的 frozen install、typecheck、lint、unit、production build 和完整 Electron E2E 通过。
+2. 四个目标的最终产品产物验证与 Pi smoke 均通过，且报告对应同一 Git commit。
+3. Spec 17.3 场景与性能预算通过，没有源码目录、staging 目录或开发 fallback 代替最终产物证据。
+4. 真实 Provider 若未验证，已由发布负责人显式接受上述风险，并保持非 Pass 状态。
+
+## 整版本回滚
+
+Pi 与旧运行时之间只支持完整应用版本回滚，不支持运行时组件级回滚或混装：
+
+1. 停止发布和自动更新，完整备份目标用户数据目录及项目中的 `.niancode` 数据。
+2. 退出 Makelore，确认没有 Pi worker 或安装器进程仍在运行。
+3. 安装上一完整、已验证的应用版本；不得把旧 runtime 覆盖到新版本 `resources`，也不得保留新旧文件拼接后的安装目录。
+4. 旧版本只继续使用其原本可读的旧 Conversation。升级后新建的 Pi Conversation 保留在磁盘中，但对旧版本不兼容，不能读取或续写。
+5. 需要重新升级时，安装完整 Pi 版本并重新执行该版本的项目迁移与一次性说明流程；不要在不同版本间复制 Session 文件。
+
+回滚完成后，应验证应用标识与用户数据目录未改变、旧 Conversation 仍可按旧版本能力读取、Pi Conversation 字节未被旧版本改写。任何需要手工编辑 Conversation 文件才能恢复的情况都应停止操作并保留备份。
