+# Task: Limit conversation unread badge triggers
+
+## Identity
+
+- Task ID: 20260902-conversation-badge-a7c49e
+- Mode: Feature
+- Branch: codex/20260902-conversation-badge-a7c49e-conversation-badge-a7c49e
+- Worktree: /Users/inmanx/Documents/makelore-conversation-badge-a7c49e
+- Base commit: 301c1496b0a3a1af3b9443a68a67de8dfea45749
+- Owner: codex
+- Status: Ready for integration
+
+## Scope
+
+- Limit the Makelore Code Conversation-list red unread marker to hidden
+  Conversations that newly require user interaction or whose current task has
+  reached a terminal result.
+- Keep assistant streaming content, thinking, tool progress, and individual tool
+  failures visible in the timeline without treating them as new-message badge
+  triggers.
+- Add focused Renderer-store coverage and an Electron production-seam regression,
+  and synchronize the current behavior in `README.md`.
+
+## Intent And Constraints
+
+- Preserve Conversation-local Snapshot/Patch reduction, generation/sequence
+  recovery, selected-Conversation read clearing, and lightweight hidden summaries.
+- Do not change Electron Main, public contracts, runtime error semantics,
+  Conversation metadata storage, or the sidebar presentation itself.
+- A new pending select/confirm/input/editor interaction must set the marker for a
+  hidden Conversation. A new completed, failed, or aborted run terminal must also
+  set it.
+- Repeated updates to an already-pending interaction or an already-terminal run
+  must not recreate a marker the user has already cleared.
+- Work in the isolated worktree because local `main` is owned by the completed
+  unsigned-macOS-package task; that task has no semantic or file overlap.
+
+## Outcome
+
+- Replaced the prior `assistant message.upsert` unread trigger with a transition
+  predicate over the target Conversation's previous and reduced Snapshots.
+- The predicate recognizes only a newly pending interaction or a newly terminal
+  run. Terminal identity is compared by run id and terminal reason so unrelated
+  late patches do not recreate a cleared marker.
+- Assistant stream start/update, thinking, tool lifecycle, and `tool.upsert` error
+  patches no longer mark a hidden Conversation unread. If the whole run later
+  settles, its completed/failed/aborted transition still marks it.
+- Extended the controllable Electron EventSource fixture and added a real sidebar
+  assertion covering process failure, pending confirmation, read clearing, and
+  final task settlement.
+- Updated `README.md` with the user-visible badge rule. No Main/runtime/API/storage
+  behavior changed.
+
+## Verification
+
+- Red phase: the focused store suite failed four assertions against the prior
+  assistant-message trigger, covering the unwanted process marker and the missing
+  interaction/failed/aborted terminal markers.
+- `pnpm exec vitest run tests/unit/coding-conversations-store.test.tsx --maxWorkers=1`:
+  passed, 1 file / 28 tests.
+- `pnpm exec vitest run tests/unit/coding-chat-panel.test.tsx --maxWorkers=1`:
+  passed, 1 file / 17 tests.
+- `pnpm run typecheck`: passed.
+- `pnpm run lint:check`: passed with 0 errors and 5 pre-existing warnings outside
+  the changed files; scoped ESLint on all changed TypeScript files passed cleanly.
+- `pnpm test`: passed; functional stage 212 files / 1,735 passed / 3 skipped,
+  isolated pressure stage 1 file / 1 passed.
+- `pnpm run build:vite`: passed for Renderer, Electron Main, Preload, and utility;
+  only existing Browserslist, dynamic-import, and chunk-size warnings remained.
+- `pnpm exec playwright test tests/e2e/pi-coding-first-chat.spec.ts`: passed, 3/3.
+- All project commands used the pinned pnpm 10.33.4. `git diff --check` passed.
+
+## Follow-ups
+
+- None.
+
+## Promotion Candidates
+
+- Target: `.project-docs/30-worklog/current-state.md`
+  Proposal: record that a hidden Code Conversation's red unread marker now signals
+  only newly pending user interaction or a newly terminal completed/failed/aborted
+  task, while assistant/tool process updates and individual tool failures remain
+  non-notifying.
+  Evidence: `src/stores/coding-conversations.ts`, focused 28-test store suite, and
+  the 3/3 Electron `pi-coding-first-chat` production-seam run.
+  Future impact: future patch types and sidebar changes should preserve the
+  distinction between process visibility and user-attention notification.
+  Semantic conflicts: none; ADR-006's Snapshot/Patch and per-Conversation isolation
+  boundaries are unchanged.
+  Human confirmation required: no.

 - Makelore 在应用侧按 Session 独立提交、跟踪和隔离运行状态，不使用“当前对话正在回复”的全局界面锁；同一 Session 的后续消息仍按顺序排队。最终产品中的 Pi 运行时会通过受控 Provider-shaped 回环 smoke 验证同一 Agent Server 内多个 Conversation 逻辑线程的重叠执行、状态隔离、凭证引用隔离、单线程关闭和 Server 崩溃后重启，以及独立子 Agent 进程的隔离与回收；真实外部 Provider 的并发、限流、协议兼容和凭证隔离仍是独立风险，未执行真实 Provider 验证时不得标记为 Pass。
 - 首次发送会立即生成稳定的乐观用户消息；HTTP 202 只表示本地 Agent 已接收。后续失败不会删除已接受消息，不确定交付不会自动重发；准备失败可在目标 Conversation 上手动恢复。
 - 运行中的 Conversation 可把新消息作为 steer 引导当前回答或 follow-up 排到下一轮，并显示队列位置；队列正常在 `agent_settled` 后释放，用户可中止当前运行。若 Pi 已终结但该握手丢失，Main 会在 30 秒宽限后仅探测目标线程：权威 idle 状态会补齐持久化最终回复并 exactly-once 释放 ownership，矛盾状态则显式失败该目标，且不会重放已接受请求。select/confirm/input/editor 交互在输入区上方回答，select 除预设选项外支持自由输入；交互提交或取消后立即从输入区移除，失效请求会就地提示并允许重试或取消。
+- 隐藏 Conversation 的红色新消息标记只在出现新的待回答交互，或当前任务进入 completed、failed、aborted 终态时设置；助手流式文字、思考、工具过程和单个工具失败不会提前触发红点。
 - 核心聊天页标题栏左侧只显示 Conversation 名称，必要的中止/恢复入口保留在右侧；不再展示 Pi 空闲/运行副标题。对话列表栏只显示项目名称和项目设置入口，不显示“Pi 本地对话”副标题；全局品牌 Logo 贴齐窗口最右边缘。归档、未读、整段 Conversation 分支和编程工具抽屉均不占用标题栏。从已持久化的 user 消息仍可“从这里创建新对话分支”，assistant 消息和未持久化消息不提供该动作；分支只创建新的 Conversation 历史，不表示文件回滚。Pi 的工具调用与浏览器附件继续在对应的对话过程节点中按需展开；分享、待办、全局运行时和 revert/unrevert 不属于该产品界面。
