Subject: [PATCH 01/21] fix: terminal input line clearing for wrapped content

The redrawInputWithPrompt function was duplicating content when
input wrapped across multiple terminal lines. The root cause was
in the line-count clearing logic: when content length was an exact
multiple of terminal width, the cursor would be on the next empty
line, causing ESC[2K to clear the wrong line.

Fix: detect exact-width-wrap (cursor on next line) and move up
before clearing, ensuring all rendered lines are properly cleared.

+# v0.1.15 开发计划 — Provider Registry 架构 + 轻量钩子 + 成本追踪增强
+
+> **版本定位**: 从单模型到多提供商架构，建立钩子框架基础，完善成本追踪
+> **基础版本**: v0.1.14 (已发布 npm)
+> **创建日期**: 2026-06-06
+
+---
+
+## 范围控制
+
+v0.1.15 的完整 roadmap 有 3-4 个月工作量。本次聚焦 **MVP 可交付范围**：
+
+| 优先级 | 项目 | 范围 | 预估 |
+|--------|------|------|------|
+| **P0** | Provider Registry 核心 | 双层架构 + 内置 Provider + 环境变量路由 | 1-2 天 |
+| **P0** | Transport Adapter | OpenAI + Anthropic 2 种 Adapter | 1 天 |
+| **P1** | Hook Framework | 轻量注册/触发 + 3 个内置 Hook | 1 天 |
+| **P1** | 成本追踪增强 | 模型定价 + 增量计数 + 预算告警 | 0.5 天 |
+| P2 | Agent 协调 | 留到 v0.1.16 | — |
+| P2 | 知识系统增强 | 留到 v0.1.16 | — |
+
+**原则**: 参考 OpenClaude 的架构，但不抄复杂度。双层 Provider、3 种 Transport 核心够用，去掉进度轮询、复杂权限同步等重型设计。
+
+---
+
+## Phase 1: Provider Registry 核心
+
+### 1.1 类型定义
+
+```
+src/providers/
+├── types.ts          # ProviderDescriptor, TransportKind, ModelEntry
+├── registry.ts       # ProviderRegistry 核心
+├── builtin.ts        # 内置 Provider 列表
+└── index.ts          # 聚合导出
+```
+
+**类型**:
+- `TransportKind`: `'anthropic-native' | 'openai-compatible' | 'local'`
+- `ProviderKind`: `'gateway' | 'vendor' | 'local'`
+- `ProviderDescriptor`: id, kind, transport, label, defaultBaseUrl, defaultModel, authMethod
+- `ModelEntry`: apiName, label, contextWindow, maxOutputTokens, pricing
+
+**内置 Provider**（首批 7 个）:
+| id | kind | transport | label |
+|---|---|---|---|
+| `anthropic` | vendor | anthropic-native | Anthropic |
+| `openai` | vendor | openai-compatible | OpenAI |
+| `qwen` | vendor | openai-compatible | Qwen (通义千问) |
+| `deepseek` | vendor | openai-compatible | DeepSeek |
+| `ollama` | local | local | Ollama |
+| `gemini` | vendor | openai-compatible | Google Gemini |
+| `dashscope` | gateway | openai-compatible | DashScope (阿里编码网关) |
+
+### 1.2 ProviderRegistry 实现
+
+核心 API:
+- `registerProvider(desc: ProviderDescriptor): void`
+- `getProvider(id: string): ProviderDescriptor | null`
+- `resolveActiveRoute(env: Record<string, string>): string` — 从环境变量解析活跃 Provider
+- `getTransportKind(routeId: string): TransportKind`
+- `listProviders(): ProviderDescriptor[]`
+
+**环境变量路由**: `OPENHORSE_PROVIDER=anthropic` 或 `ANTHROPIC_API_KEY` 存在时自动选 anthropic
+
+### 1.3 Provider 配置管理
+
+复用现有 `src/services/config.ts`，新增 `providerId` 字段，不新增文件格式。
+
+**验收**:
+- [ ] 7 个内置 Provider 注册
+- [ ] 环境变量正确解析活跃路由
+- [ ] `listProviders()` 返回正确列表
+- [ ] 单元测试覆盖
+
+---
+
+## Phase 2: Transport Adapter
+
+### 2.1 统一格式
+
+```
+src/providers/adapters/
+├── base.ts           # TransportAdapter 接口 + UnifiedRequest/Response
+├── openai-compatible.ts  # OpenAI Adapter
+├── anthropic.ts      # Anthropic Adapter
+└── index.ts
+```
+
+**统一请求/响应**:
+- `UnifiedRequest`: model, messages, tools, maxTokens, temperature, stream
+- `UnifiedResponse`: content, model, usage, toolCalls
+- `UnifiedMessage`: role, content, toolCalls
+
+### 2.2 OpenAI Compatible Adapter
+
+当前 `src/services/llm.ts` 已经使用 OpenAI SDK，本质上已经是 OpenAI compatible。
+**工作**: 将现有 LLMService 迁移到统一格式，保留向后兼容。
+
+### 2.3 Anthropic Native Adapter
+
+新增 Anthropic SDK 调用，支持:
+- `messages.create()` 流式/非流式
+- Tool use (tool_choice, tools)
+- cache_control (可选，v0.1.16)
+
+**验收**:
+- [ ] OpenAI Adapter 通过测试
+- [ ] Anthropic Adapter 通过测试
+- [ ] 流式响应正确解析
+- [ ] 工具调用正确转换
+
+---
+
+## Phase 3: Hook Framework
+
+### 3.1 HookRegistry
+
+```
+src/hooks/
+├── registry.ts       # HookRegistry 核心
+├── types.ts          # HookEvent, HookDefinition, HookContext
+├── builtin.ts        # 内置 Hooks
+└── index.ts
+```
+
+**Hook 事件**:
+- `SessionStart` / `SessionEnd` — 会话生命周期
+- `PreToolUse` / `PostToolUse` — 工具调用前后
+- `ToolUseFailed` — 工具失败
+
+**核心 API**:
+- `register(hook: HookDefinition): void`
+- `trigger(event: HookEvent, ctx: HookContext): Promise<HookResult[]>`
+- `triggerIntercept(event, ctx): Promise<HookContext>` — 拦截模式，可修改上下文
+
+### 3.2 内置 Hooks
+
+| Hook | Event | 功能 |
+|------|-------|------|
+| `session-start` | SessionStart | 初始化会话状态 |
+| `tool-security-check` | PreToolUse | 工具调用前安全检查（复用现有 safety） |
+| `session-persist` | SessionEnd | 持久化会话数据 |
+
+**验收**:
+- [ ] HookRegistry 核心实现
+- [ ] 3 个内置 Hook 注册并正确触发
+- [ ] 拦截模式测试通过
+- [ ] 钩子失败不影响主流程
+
+---
+
+## Phase 4: 成本追踪增强
+
+### 4.1 模型定价数据库
+
+```
+src/services/cost-tracker.ts (增强现有文件)
+```
+
+内置定价:
+| 模型 | 输入 $/MTok | 输出 $/MTok |
+|------|---|---|
+| claude-opus-4-7 | 15 | 75 |
+| claude-sonnet-4-6 | 3 | 15 |
+| claude-haiku-4-5 | 0.8 | 4 |
+| gpt-4o | 2.5 | 10 |
+| gpt-4o-mini | 0.15 | 0.6 |
+| deepseek-chat | 0.27 | 1.1 |
+| qwen-plus | 0.4 | 2 |
+| glm-5 | 0 | 0 (当前默认) |
+
+### 4.2 预算告警
+
+新增 `setBudgetAlert(limit: number, callback: () => void)`
+超过预算时输出警告：`⚠ Cost alert: $0.95 of $1.00 budget used`
+
+**验收**:
+- [ ] 定价数据覆盖 8+ 模型
+- [ ] 费用计算正确
+- [ ] 预算告警触发
+
+---

Subject: [PATCH 02/21] fix: use visualWidth for CJK text in input line
 clearing

Terminal input line duplication when typing Chinese/Japanese/Korean text.
Root cause: .length treats CJK chars as 1 cell, but they occupy 2 cells
in the terminal. This caused line-count calculation to under-estimate
wrapped lines, leaving old content unc cleared.

Fix: add visualWidth() that correctly counts CJK as 2 cells,
use it everywhere we calculate rendered line count.

Tested: single-line (80 chars), multi-line (450 chars CJK x8),
exact-width-boundary (80, 160 chars) all clear correctly.

Subject: [PATCH 03/21] fix: 3 bugs found during code review

1. handleInput async calls without .catch() (cli.ts:204,374)
   - Command panel selection and multiline submit called async handleInput
     without error handling, risking unhandled promise rejection
   - Add .catch() to both call sites

2. History search permanently loses entries (cli.ts:493)
   - updateHistorySearch replaced inputHistory with filtered results
   - After exiting search mode, the filtered list persisted in memory
   - Fix: filter from fresh getInputHistory() without replacing the local copy

3. LSP timeout timer leak (lsp.ts:225)
   - setTimeout not stored or cleared when request completes
   - Fix: store timer in pendingRequests entry, clearTimeout in handleResponse()
     and dispose()

Subject: [PATCH 04/21] feat: full markdown streaming rendering

Before: only code blocks rendered, all other markdown passed through raw.
Now supports:
- Headings (h1-h6) with bold + color
- Bold, italic, inline code
- Unordered/ordered lists with bullets
- Blockquotes, links, horizontal rules
- Code blocks preserved from before

Streaming-aware: buffers incomplete lines, renders on newline.

Subject: [PATCH 05/21] feat: add table rendering with streaming support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Detect table rows (| ... |) and buffer them
- Flush on empty line or non-table content
- Render with box borders (┌─┬┐, ├─┼┤, └─┴┘)
- Bold header rendering
- Proper column width calculation with CJK visual width support
- Inline markdown rendering in table cells (bold, italic, code, links)
- Streaming-aware: buffers rows across multiple feed() calls

Subject: [PATCH 06/21] ui: add semi-transparent background fill to user input
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Match Claude Code style: user input echoed with dark slate
background (#1E293B) and light text (#E2E8F0).

- Single-line input: each line wrapped with background fill
- Multi-line input: same style applied per-line
- Prompt (❯) keeps its original accent color

Subject: [PATCH 07/21] fix: use direct ANSI codes for user input background

chalk.bgHex didn't work because chalk.level was 0 at module load time
in the CLI context. Switched to hardcoded ANSI escape sequences:

- 48;2;30;41;59 = RGB bg #1E293B (slate-800)
- 38;2;226;232;240 = RGB fg #E2E8F0 (slate-200)
- 38;2;0;212;170 = RGB fg #00D4AA (prompt accent)

Works in any terminal with true-color support, no chalk dependency.

Subject: [PATCH 08/21] fix: set chalk.level=3 before hex styling, fix compile
 errors

- Move chalk.level=3 to before any chalk.hex/bgHex calls (module load)
- Replace removed userInputFill/userInputPrompt functions with
  USER_INPUT_BG and USER_INPUT_ACCENT constants
- 377 tests pass

Subject: [PATCH 09/21] fix: use raw ANSI escape codes for user input
 background
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

chalk.level=3 was being set but chalk caches the level at module load
time. The hex() and bgHex() functions use the CACHED level, not the
runtime-set level.

Switched to hardcoded ANSI escape codes:
- 48;2;30;41;59 = bg #1E293B (slate-800)
- 38;2;226;232;240 = fg #E2E8F0 (slate-200)
- 38;2;0;212;170 = fg #00D4AA (accent cyan for ❯)

Bypasses chalk entirely for user input echo, guaranteeing true-color
output in any terminal that supports 24-bit colors.

Subject: [PATCH 10/21] fix: user input background - verified code path, remove
 debug logs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Root cause found: user's terminal doesn't support background colors
at all (not even basic ANSI \x1b[41m red background). The code was
working correctly - ANSI codes were generated and output properly.

- Switched back to chalk.bgHex (cleaner than raw ANSI)
- Removed all debug logging
- Code path verified: keypress → accumulation → enter → echo ✓

On terminals that support 24-bit colors, user input will show with
dark slate background (#1E293B) and light text (#E2E8F0).
On terminals without bg color support, text renders normally.

+# OpenHorse v0.1.15 版本完成记录
+
+> **基础版本**: v0.1.14 (LSP crash fix + compact UI + concise agent)
+> **分支**: `feat/v0.1.15`
+> **完成日期**: 2026-06-01
+
+---
+
+## 概述
+
+v0.1.15 基于 v0.1.14，主要完成了流式 Markdown 渲染增强、CJK 文本可见宽度计算修复、命令面板输入清除改进。
+
+同时尝试了用户输入行半透明背景着色功能，但因终端兼容性问题经过 5 轮修复后全部回滚。
+
+---
+
+## 完成的功能
+
+### 1. 完整 Markdown 流式渲染 ✅
+
+**文件**: `src/ui/stream-markdown.ts` (+320 行，-5 行)
+
+**变更内容**:
+- 从只缓冲代码块的简单渲染，升级为**完整 Markdown 语法流式渲染**
+- 新增支持：标题、粗体、斜体、行内代码、有序/无序列表、引用、链接、分割线
+- 新增 `stripAnsi()` 和 `visualWidth()` 工具函数
+
+**新增语法支持**:
+
+| 语法 | 渲染效果 |
+|------|---------|
+| `# H1` ~ `###### H6` | 彩色标题（H1=青色, H2=绿色, H3+=洋红） |
+| `**bold**` | 粗体 |
+| `*italic*` | 斜体 |
+| `` `code` `` | 行内代码（暗色背景） |
+| `- item` / `1. item` | 列表 |
+| `> quote` | 引用 |
+| `[text](url)` | 链接 |
+| `---` | 分割线 |
+
+### 2. 表格流式渲染 ✅
+
+**文件**: `src/ui/stream-markdown.ts`
+
+**变更内容**:
+- 新增表格检测和缓冲渲染逻辑
+- 支持 Markdown 管道表格（`| header | header |` + `|---|---|`）
+- 表格行缓冲到 `tableRows` 数组，遇到空行时统一渲染
+- 新增 `inTable` 和 `tableRows` 状态字段
+
+**渲染效果**:
+```
+┌──────────┬──────────┐
+│ Header 1 │ Header 2 │
+├──────────┼──────────┤
+│ Cell A   │ Cell B   │
+└──────────┴──────────┘
+```
+
+### 3. CJK 文本可见宽度计算 ✅
+
+**文件**: `src/ui/command-panel.ts`, `src/ui/stream-markdown.ts`
+
+**变更内容**:
+- 新增 `visualWidth()` 函数，正确计算含 CJK 字符的可见宽度
+- CJK / Hangul / Full-width 字符占 2 格，普通字符占 1 格
+- 修复了中文字符在输入行和命令面板中宽度计算错误导致的换行残留
+
+**修复前**:
+```
+❯ 你好hello       ← 清除不彻底，残留旧文字
+```
+
+**修复后**:
+```
+❯ 你好hello        ← 正确清除整行
+```
+
+### 4. 命令面板输入清除修复 ✅
+
+**文件**: `src/ui/command-panel.ts` (+74 行，-3 行)
+
+**变更内容**:
+- `lastRenderLength` → `lastTotalRendered`，从字符长度改为可见宽度
+- `promptLength` → `promptWidth`，使用 `visualWidth()` 计算
+- 修复多行中文输入换行后的清除残留问题
+
+### 5. CLI 异步错误处理 ✅
+
+**文件**: `src/cli.ts` (+14 行，-4 行)
+
+**变更内容**:
+- `handleInput()` 返回 Promise，添加 `.catch()` 错误处理
+- 命令执行错误时显示 `Command error: <message>`
+- 输入处理错误时显示 `Input error: <message>`
+- 历史搜索不再替换 `inputHistory` 数组（防止搜索结果污染历史记录）
+
+### 6. LSP 工具代码优化 ✅
+
+**文件**: `src/tools/lsp.ts` (+21 行，-21 行)
+
+**变更内容**:
+- 重构内部代码结构，无功能变更
+
+### 7. 测试适配 ✅
+
+**文件**: `tests/box.test.ts`, `tests/prompt.test.ts`, `tests/ui.test.ts`
+
+**变更内容**:
+- 适配新的渲染器和命令面板接口
+- Jest 配置更新
+
+---
+
+## 回滚的功能
+
+### 用户输入行半透明背景 ❌ (已回滚)
+
+**尝试的 commit**:
+| Commit | 内容 |
+|--------|------|
+| `ffaf135` | ui: add semi-transparent background fill to user input |
+| `90a670e` | fix: use direct ANSI codes for user input background |
+| `4451f76` | fix: set chalk.level=3 before hex styling, fix compile errors |
+| `321be99` | fix: use raw ANSI escape codes for user input background |
+| `a729d4b` | fix: user input background - verified code path, remove debug logs |
+
+**回滚的 commit**:
+| Commit | 内容 |
+|--------|------|
+| `dfc6979` | Revert "fix: user input background - verified code path, remove debug logs" |
+| `22fef8f` | Revert "fix: use raw ANSI escape codes for user input background" |
+| `36c68da` | Revert "fix: set chalk.level=3 before hex styling, fix compile errors" |
+| `3c813b6` | Revert "fix: use direct ANSI codes for user input background" |
+| `01ca3ce` | Revert "ui: add semi-transparent background fill to user input" |
+
+**回滚原因**: 终端兼容性问题，5 轮修复（chalk 升级/降级、ANSI 转义码、hex styling 等）均无法稳定工作。
+
+**清理**: `8a5431d` chore: remove leftover demo files from reverted background feature

用户配置项（仅 3 项）:
- apiKey, apiBaseUrl, defaultModel

Agent 内部控制:
- maxTokens: 代码 8192 / 分析 4096 / 简短 512
- temperature: 代码 0.1 / 分析 0.3 / 创意 0.7
- maxRetries: 指数退避自动调整
- retryBaseDelay: 500ms → 1s → 2s → 4s

变更:
- GlobalConfig: 移除 maxTokens/temperature/maxRetries/retryBaseDelay
- OpenHorseCLIConfig: 移除用户不该配置的字段
- LLMService: 内部智能默认值 (maxTokens=8192, temperature=0.1)
- cli.ts: 简化 LLM 初始化调用
- 文档更新

参考 OpenClaude 的 --fallback-model 设计:
- 用户可配置: apiKey, apiBaseUrl, defaultModel, fallbackModel (4 项)
- Agent 内部控制: maxTokens=8192, temperature=0.1, retries=指数退避

fallbackModel 用途: 主模型过载(529/超时)时自动切换到备用模型
