+- ✅ **后台进程池（智能体运行/管理长驻进程）**：新增 `subsystems/process_manager.py`（`ProcessManager` 全局单例）+ `tools/process_tools.py` 5 个 worker 执行面工具（`bg_run` / `bg_write` / `bg_list` / `bg_output` / `bg_kill`），弥补 `run_command` 同步阻塞、超时即杀的不足——dev server / 训练任务 / watch 等长驻进程可后台启动、跨会话管理：
+  - **生命周期语义（三决策）**：用户中断（Ctrl+C/取消事件）不影响后台进程；aibox 退出经 atexit 统一收尾（非 detach 全杀，`detach=true` 豁免但脱离句柄管理）；注册表跨会话/跨子代理共享（观察面全局可见；写/杀按属主隔离——T22，仅启动者所在会话可操作，定时任务 AI 为精简 `task` profile 且无 update_identity/update_soul/set_proxy）
+  - **交互式 I/O（stdin 管道 + watermark 写读对齐）**：stdin 挂管道，`bg_write` 向行协议进程（REPL / 问答式 CLI）写入一行，返回 **watermark**（`[stdin]` 回显行序号）——`bg_output(since=watermark)` 得到的必然且仅是该输入引发的响应（写读配对）；`wait_lines=N` expect 式同步等待；回显行入环形缓冲与 log 镜像（tail 可见完整交互时序）；写入 watchdog 线程兜底（进程不读 stdin 管道写满时不阻塞工具线程）；单次写入上限 64KB
+  - **输出缓冲**：每进程有界环形缓冲（默认 256KB，`buffer_per_process` 可调），单行截断 16KB；`bg_output` 支持 `tail` 尾读与 `since` 游标增量续读（淘汰行如实提示），单次默认 64KB、上限 1MB；`bg_run log_file=true` 输出同步 tee 到 `workspace/bg_<句柄>.log`（无界全档，`[stdin]` 回显同入档，可被 run_command 的 tail/cat 原生读取）
+  - **三级优雅终止**：`bg_kill` 关 stdin（行协议进程见 EOF 常自行退出）→ SIGTERM 宽限（grace 比例 4:6）→ SIGKILL 兜底；`force=true` 直接 SIGKILL；shutdown 收尾同样先关 stdin
+  - **安全边界**：运行中上限 16 / 总条目上限 32（LRU 淘汰已退出条目）；`background_processes` 配置节（含 `enabled` 双闸：`commands.enabled` 关闭时一并拒绝）；`proc_name` 标签 ≤64 字符且拒绝控制字符（M5 惯例）；POSIX `start_new_session` + 进程组终止（对齐执行器 L9 语义），Windows `taskkill /T /F` 收割进程树；TTL `max_lifetime` 惰性清理（默认 0 不启用）；凭据类交互（sudo -S 喂密码）会留对话记录，敏感凭据走环境变量注入（工具描述已指引）
+  - **实现要点**：H2 reader 线程模式复用（EOF 即 poll 收割防僵尸）；`list_procs` 惰性刷新全表状态；`proc_name` 命名规避 `ToolRegistry.execute_tool(name=...)` 首参撞名；编排者误调拦截表 `WORKER_ONLY_TOOLS` 同步纳入；无 TTY 的适用边界（全屏程序不可用、行缓冲指引）写入工具描述供模型自检
+  - **测试**：新增 `tests/test_process_manager.py` 39 项（生命周期/游标续读/环形淘汰/单行截断/上限/TTL/收尾/工具分发/禁用闸/watermark 对齐/回显/sync 等待/超时/EOF 优雅终止/log tee/注册表分发），Windows 开发机 532 passed / 4 failed（平台环境项，与代码无关）
+
+### v3.7
+- ✅ **第六轮安全审计 + Batch L 修复（2026-08-20，交叉验证轮：Batch K 回归验证 / 并发与生命周期 / 降级路径 / 修复间相互作用，4 路并行审读 + 主审逐条复核）**（完整记录见 [docs/reports/aibox_audit_20260817.md](../docs/reports/aibox_audit_20260817.md) §16）：
+  - **Batch K 回归验证**：J1~J16 逐项在位、零回归，无修复引入的缺陷；历届 Batch E~I 修复抽查（executors reader 收尾、1MB 输出上限、registry 流式预算、broadcast 快照等）均在位
+  - **Batch L（R1~R3 低危全落地）**：R1 `/memos` WS 命令 strptime 容错（畸形 reminder_time 按"待执行"展示，不再整体"处理失败"）；R2 移除 `handle_interrupt` 对全局 `ai_manager.command_executor` 的取消（WS 中断不再误杀 CLI 主 AI 子进程）；R3 `unregister` 补齐回收（关闭 websocket + 取消在途处理任务，broadcast 超时路径与连接关闭路径行为对齐，半开连接不再泄漏）
+  - **测试**：新增 `tests/test_l_fixes.py` 6 例（R1 容错与语义不回归 ×2 / R2 范围收窄与中断能力不回归 ×2 / R3 回收与幂等 ×2）；Linux 维持 490 passed，Windows 开发机 493 passed / 4 failed（均为平台环境项，与代码无关）
+
+### v3.6
+- ✅ **交互式大模型接入点管理（[model_config.py](model_config.py)）**：菜单式 列表 / 添加 / 删除 / 连通性验证，不用手写 `config.json`；Key 仅记录环境变量名不落盘（空 = 免密本地端点）；删除自动清理其他档案的 fallback 引用；默认档案经 `api.default_model` 生效（详见 [模型接入点管理](#管理大模型接入点不用手写配置)）
+- ✅ **第五轮安全审计（2026-08-19，4 路并行审读 + Linux PoC 2/2 实证，发现 J1~J16：高危 2 / 中危 5 / 低危 6 / 信息 3）**（完整记录见 [docs/reports/aibox_audit_20260817.md](../docs/reports/aibox_audit_20260817.md) §13~§14）：
+  - **K1（J1 高危·任务系统投毒）**：畸形时间/数字字段经 CLI/WS/memo 工具三入口零校验入库 → 调度器失败热循环 + 每个新连接握手即崩——入库端统一校验（`reminder_time`/`repeat_end_time` strptime 预检、`repeat_interval` 强转 int、`repeat_type` 白名单）、调度器预检失败按到期执行（Q5 语义）、`get_pending_tasks_for_user` 解析失败按到期展示、`register` 移入 try/finally（会话登记不再泄漏）；附带修复 `add_user_task` 缺失 `repeat_end_time` 参数透传
+  - **K2（J2 高危·前端 XSS）**：三页面 7 处 `marked.parse` 直渲（AI 输出/命令结果全链路 innerHTML）统一改经 `renderMarkdown()` + DOMPurify（缺失时退化为转义文本防 XSS 兜底）；`entry1.addSystemMessage` 改 DOM 构建 + textContent；任务标题改 createTextNode；CDN 脚本（marked/hljs/socket.io/DOMPurify）补 SRI integrity（J13）
+  - **K3（中危）**：FTS 外部内容表删除换序——先删 `memories_fts` 再删 `memories`，索引残留消除（J3，PoC 实证）；config/prompt/对话写路径统一原子写（`common/atomic.py`，mkstemp + fsync + os.replace）+ 损坏备份 `config.json.corrupt.<时间戳>` 拒绝覆盖（J5）；PromptManager/ConfigManager 单例初始化纳入锁（J6，并发首例不再双重加载系统提示词）
+  - **K4（中危）**：`model_config.py` 连通性验证异常消息复用 `_sanitize_log_msg` 脱敏（J4，Bearer 令牌不再进终端）；`broadcast` 改每客户端并发发送 + `asyncio.wait_for` 超时（`broadcast_send_timeout` 默认 5s），超时即 unregister——僵死客户端（半开 TCP）不再卡死广播与调度器循环（J7）
+  - **K5（低危随批）**：J8 交互输入容错（非法温度/超时友好报错）；J9 MemoDatabase WAL + busy_timeout=10000 覆盖全部写路径；J10 memo 批量删除补实现（`memo_ids`）；J11 `/new` 取消-重置竞态（排队 reset 等待 is_processing 清零）；J12 skills 注入面（nmap hosts `shlex.quote`、screenshot PowerShell 单引号转义、SKILLS_FORMAT.md 新增"安全边界"节）；J14 voice_client 死代码/僵尸连接/录音残留清理；J15 死代码移除（`full_response_queue` 等）+ 未知 task action 明确报错 + 广播门控对齐 + 热路径日志降级；J16 `--help` 输出 2000 上限 + 同名技能键确定性解决
+- ✅ **测试**：490 项全过（Linux 环境；第五轮新增 Batch K 35 项 + 子代理 max_turns 回归 14 项；`test_execute_timeout`/`test_flat_api_still_reads_key_file` 为 Windows 向用例，Linux 预存失败与本轮无关）
+
+### v3.5
+- ✅ **安全审计与修复（第三轮 Batch G + 第四轮 Batch H + 遗留收尾 Batch I）**（完整记录见 [docs/reports/aibox_audit_20260817.md](../docs/reports/aibox_audit_20260817.md)）：
+  - **Batch G（llm 加固 + 线程生命周期 + 取消传播 + DB 事务）**：
+    - llm_client：非瞬时 HTTP 错误体截断 `[:200]`（密钥/错误页不进异常栈）、Retry-After 上限 cap 3600s、fallback 档案缺 model 跳过并告警、fallback 去重、删除 `LLMClient._cancelled` 死状态、FailoverClient 并发契约文档化
+    - 子代理取消传播：`run_full_subagent` 共享父 `_cancel_event` + 0.2s 观察者线程转发深度中断（强关在途 HTTP、kill 子进程）；`SubAgentTool` 构造注入父事件
+    - drain 线程重构：批次级单线程 + stop 事件 + try/finally 统一回收（消除每次工具调用泄漏一个常驻线程）；`/new` 的 `reset_conversation` 移入线程池（不再同步获取 `_msg_lock` 冻结事件循环）；broadcast 收窄 except + unregister 改 discard；`_processing_tasks` 改按连接的任务集合登记（关闭时取消全部在途任务）
+    - DB：FTS5 关键词双引号翻倍转义（`"` → `""`）、两处 `LIMIT` f-string 参数化、`mark_as_triggered` 读写收进单连接 `BEGIN IMMEDIATE` 事务（消灭并发触发竞态）；历史索引裸 except 收窄 + 归档文件名同秒加序号
+  - **Batch H（第四轮审计，3 路并行审读 + Linux PoC 6/6 实证）**：
+    - **H1（高危）**：修复 N5 回归——子代理共享父取消事件后首轮 think 无条件 `clear()` 会吞掉父级已置位的取消信号（用户中断 / --once 超时被绕过），共享事件时跳过 clear + 父已取消直接早退
+    - `/reload_prompts` 移入线程池（N3 同类遗漏）；技能扫描（串行 `--help` 子进程）启动前预热，不再在首条消息/首个任务时冻结事件循环
+    - 调度器任务级超时（`scheduler.task_timeout`，默认 600s）——AI think 卡死不再停摆整个调度循环
+    - `get_recent_memories(limit=None)` 默认上限（不再全表加载）；`memo delete` 改物理删除（此前只标记完成）；`PromptManager.reload` 本地构建后原子替换（并发读者不再读到空/半截系统提示词）
+    - read_file 的 sed 参数强转 int（防引号注入）；`set_proxy` 落盘失败如实报告；SSE 非 UTF-8 行容错；persona 路径 realpath 校验（软链越界拒绝）；1MB 截断无半个字符；compressor 除零防护；InstallSkillTool 指引命令路径引用；ask_user 缺参明确报错
+    - **POSIX 进程组终止**：executor 的 `Popen` 加 `start_new_session` + 组信号 kill（组 ID 在 Popen 后立即捕获）——`(sleep 300 &)` 形态的孙进程持管道不再悬挂 reader 线程/泄漏 fd（实证修复前孙进程残留）
+    - web 工具 scheme 白名单（http/https，`file://` 等拒绝）；registry 日志打码改包含匹配（apiKey/passwd 变体）；FailoverClient 日志 Bearer 令牌正则脱敏（网关回显 Authorization 头不再进日志）
+  - **Batch I（遗留收尾）**：
+    - **N9**：prompt 写入内容长度上限（`MAX_CONTENT_LENGTH=10000`，identity/soul/status 超长拒绝）——约束持久化注入面
+    - **F5**：情绪子代理取消传播——`run_light_subagent` 改走 stream_chat + 观察者线程，用户中断可即时终止（此前阻塞至请求超时）
+    - 提醒时间格式异常任务按"到期"返回（此前被 SQL 层字符串比较静默丢弃，任务永不执行）；`mark_as_triggered` 加 `busy_timeout=10000`（多进程同库写竞争等待而非立即报 locked）
+    - 对话文件原子写（tmp + os.replace，崩溃不留半截 JSON）；`load_conversation` realpath 越界防护；WS 命令专用线程池（`/new`、`/reload_prompts` 不再占用默认池）；--once 硬超时兜底（软超时后宽限一个周期强杀进程）
+    - PromptManager 单例加锁；`limit=0` 语义修正（None 才不加 LIMIT）
+- ✅ **测试**：424 项全过（Linux 环境；Batch G 20 + Batch H 26 + Batch I 16 项新增；`test_execute_timeout`/`test_flat_api_still_reads_key_file` 为 Windows 向用例，Linux 预存失败与本轮无关）
+
+### v3.4
+- ✅ **多模型档案加固（H1/H2/H3/M1/M2/M3 六项修复）**：
+  - **H1（凭据隔离）**：档案端点环境变量取不到时直接报错，**绝不回退读 `~/.cert/deepseek.key`**（该文件为 DeepSeek 专属凭据，跨厂商复用属于泄漏）；key 文件回退仅对无档案的旧 `api` 扁平节生效
+  - **H2（schema 校验前移）**：档案缺 `api_url`/`model` 或类型错误时，解析期即抛出指明档案名与缺失字段的 `ValueError`——不再把档案名当模型名发出、不再延迟到 `requests InvalidURL` 或 API 400
+  - **H3（--model 服务模式生效）**：`--model` 升级为进程级覆盖，WebSocket 服务模式（主对话/每个会话实例/定时任务实例）与 `--once` 均生效，此前服务模式静默忽略
+  - **M2（防模型名幻觉）**：`create_subagent` 工具描述与 JSON Schema 动态携带 `models` 节可用档案名列表（默认档案标注），LLM 无从编造名称；`models` 为空时描述保持原样（零破坏）
+  - **M1（换模型同步派生引用）**：新增 `DeepSeekChat.set_client()` 统一替换 LLM 客户端——同步刷新 `compressor.llm_client` 与 `api_key`/`name` 快照；`create_subagent` 子代理换模型经此入口，压缩链不再残留默认模型
+  - **M3（reasoning 契约显式化）**：档案级 `reasoning_enabled` 从"构造后挂实例属性"改为 `LLMClient` 构造参数（三态：`True`/`False` 档案级显式、`None` 未配置回退全局），外部误设属性无从静默覆盖全局开关
+- ✅ **L 批体验与兼容修复（L1/L2/L3/L5 四项）**：
+  - **L1（展示名按档案）**：`client.name` = 档案 `display_name` > 档案名，用 Kimi/Qwen 时对话上下文不再误标 "DeepSeek"；旧扁平节保持 "DeepSeek"（零破坏）
+  - **L2（前缀逃逸）**：`--model model:NAME` 强制裸模型名语义、`--model profile:NAME` 强制档案语义（不存在时明确报错并列出可用档案），档案名与模型名歧义可逃逸
+  - **L3（档案级温度）**：档案 `temperature` 字段作为默认采样温度，优先级：CLI/调用方显式传入 > 档案字段 > 全局默认（0.7/0.3），主对话/轻量子代理/compressor 全链路生效
+  - **L5（思考流字段别名）**：`_parse_delta` 识别 `reasoning_content`/`reasoning`/`thinking`/`thinking_content` 四种常见思考字段（首个命中生效），其他厂商思考流不再静默丢失
+- ✅ **L4a（chat_completion 跨档案失败转移）**：档案新字段 `fallback`（档案名列表，一层不递归）；`create_llm_client` 构造 `FailoverClient` 包装链（主档案 + fallback）。瞬时故障（HTTP 429/5xx 抛 `TransientLLMError`、连接失败/超时）按链转移，认证/参数类 4xx 不转移（配置问题响亮暴露）；失败档案 60s 冷却；fallback 档案缺 Key 等环境问题跳过 + warning 不阻断主档案；配置结构错误（类型/不存在/自引用）启动期硬性拦截。当前覆盖对话压缩与轻量子代理链路，流式（`stream_chat`）转移属 L4b
+- ✅ **L4b（stream_chat 首事件前转移 + 中断联动）**：流式仅在**未产出任何事件**（reasoning/content/tool_call）时转移——重放对用户不可见；已产出事件后失败直接上抛（防前端重复输出/工具增量错乱）。`LLMClient.cancel()` 置 `_cancelled` 标志，`FailoverClient.cancel()` 广播整条链并置包装器标志——用户中断引发的连接异常与真实故障不可区分，凭标志跳过转移（否则用户越中断、系统越换厂商重试）；`chat_completion` 同受标志保护。链耗尽抛最后异常（既有回滚/报错处理接住），全链冷却抛 RuntimeError
+- ✅ **L4c（转移可观测性 + 预算控制 + Retry-After）**：`FailoverClient.get_stats()` 暴露 requests/failovers/cooldown_skips/exhausted 聚合计数；`on_failover(from, to, reason)` 回调（to=None 表示链耗尽，回调异常不影响主流程）供管理面/前端通知接入；档案字段 `failover_timeout_budget` 限制整链尝试总秒数（缺省不限，<=0 视为未配置），耗尽停止尝试剩余档案防超时叠加；429 响应 Retry-After（数字秒）经 `TransientLLMError.retry_after` 延长该档案冷却期（非数字格式忽略）
+- ✅ **测试**：355 项全过（H1 隔离 4 + H2 校验 6 + H3 传导 6 + M2 提示 5 + M1 替换 2 + M3 契约 4 + L 批 16 + L4a 转移 15 + L4b 流式 12 + L4c 可观测 13 项新增）
+
+### v3.3
+- ✅ **安全审计与修复**（两轮审计报告见 [docs/reports/aibox_audit_20260817.md](../docs/reports/aibox_audit_20260817.md)）：
+  - **Batch E（命令执行保护链修复）**：`CommandLineTool.execute_streaming` 纯委托注入的 executor（删除绕过 1MB/超时/中断保护的 150 行重复 Popen 实现）；`SubprocessCommandExecutor` 读取循环线程化（后台 reader 线程 + 0.1s 超时轮询，静默命令超时不再失效）；两处 `Popen` 改 `stdin=DEVNULL`（等待输入的命令不再永久挂起工具线程）；write_file 指引 heredoc 定界符唯一化；registry 流式转发循环加 3600s 总超时兜底。PoC 回归 5/5 + 全量单测通过
+  - **Batch F（凭据保护 + 线程收尾）**：
+    - **F1**：SOCKS5 代理密码不再明文落盘——`_save_config` 落盘前强制脱敏（纵深防御），新增 `password_env` 环境变量注入（对齐 `api_key_env` 惯例），旧版明文配置加载时自动迁移清除；`registry` debug 日志对 `password`/`api_key`/`token`/`secret`/`authorization` 参数打码
+    - **F2**：registry 流式转发超时路径统一清理 `tool.streaming_output`/`tool.output_queue`（消除僵尸 daemon 线程经实例属性把输出混入后续会话队列的串流路径），`stream_tool_timeout` 提为实例属性（默认 3600s，测试可调）；`SubprocessCommandExecutor` reader 线程收尾——正常 EOF 后显式 close 释放管道 fd，仍阻塞时有限 join 后放弃（daemon 兜底）；实证修正：CPython 流锁下阻塞中的 readline 无法被 `close()` 中断（首版实现致超时被拖满命令时长，已按 PoC 回归修正）
+- ✅ **测试**：272 项全过（Batch E PoC 回归 + F1 配置脱敏 3 项 + F2 超时清理/线程收尾 5 项新增）
+
+### v3.2
+- ✅ **CLI 一次性对话模式（`--once`）**（分三批落地）：
+  - **Batch A**：`--once QUERY` / `--quiet` / `--once-timeout`；不启动 WebSocket，执行后退出；回答走 stdout、过程走 stderr，可管道组合；SIGINT 与超时复用三层取消机制
+  - **Batch B**：`--no-save-memory`（`enable_memory` 开关干净禁用 MemoryTool）、`--show-reasoning`（思考流默认静默）；压缩提示改走 output_callback 不再污染 stdout；退出码 1（工具执行失败）
+  - **Batch C**：SQLite WAL（多 CLI 进程并发写锁缓解）、`--worker-only`（纯执行面 + 精简 system prompt 防人格污染）、`--model` / `--temperature` 覆盖、子代理工具失败标记透传（`_SUBAGENT_TOOL_FAILED_MARKER` → orchestrator stats）
+- ✅ **多模型档案（`models` 配置节）**：配置多个 OpenAI Chat Completions 兼容端点（DeepSeek/Kimi/Qwen/本地 Ollama 等）按档案名切换；`--model` 支持档案名与裸模型名（同端点换模型）双语义；档案级 `api_key_env` 三级语义（回退 / 显式 / 空串免密）；档案级 `reasoning_enabled` 优先于全局；`models: {}` 时零破坏回退旧 `api` 节；`llm_client.py` 增加 `openai_compatible` / `openai` provider 别名
+- ✅ **测试**：264 项全过（once 模式 15 项 + 多模型档案 17 项新增）
+
 ### v3.1
 - ✅ **修复 FTS5 中文搜索失效**（[subsystems/db.py](subsystems/db.py)）：
   - FTS5 虚拟表改用 `tokenize='trigram'` 分词器（需 SQLite >= 3.34，环境不支持时自动退回 unicode61）

+让智能体能够启动并管理长驻后台进程（dev server / 训练任务 / watch 等），
+弥补 run_command 同步阻塞、超时即杀的不足：
+  - bg 语义：start() 立即返回句柄，进程独立于对话轮次存活
+  - 有界环形输出缓冲：每进程上限 buffer_per_process（默认 256KB），
+    解决 nohup+日志文件方案输出无界增长的问题
+  - 注册表：自增句柄跨会话/跨子代理可见（全局单例）
+  - 生命周期：惰性状态收割（reader 线程 EOF 即 poll 收割防僵尸）+
+    TTL 惰性清理 + 退出统一收尾（非 detach 进程默认全杀）
+
+安全边界（对齐 SubprocessCommandExecutor 既有惯例）：
+  - 输出单行截断 16KB，防超长单行撑爆内存
+  - 运行中进程数上限（默认 16）+ 总条目上限（默认 32，已退出条目
+    保留尾部输出供验尸，LRU 淘汰）
+  - POSIX start_new_session + 进程组信号（L9 语义：孙进程不悬挂）；
+    Windows 无进程组概念，回退单进程 terminate/kill
+  - 中断语义：用户 Ctrl+C / 取消事件不影响后台进程（后台的本意就是
+    脱离本轮对话生命周期）；aibox 进程退出时经 atexit 统一收尾，
+    detach=true 的进程豁免

+覆盖 aibox.py run_full_subagent 的轮次限制链路（think_with_limit 补丁）：
+  - 超限拦截：任务轮 LLM 调用被限制在 max_turns 次，超限递归返回哨兵串
+  - 哨兵串文本契约（"已达到最大对话轮次，任务结束。"）
+  - 收尾报告：超限/正常结束均由 original_think 绕过轮次限制生成，作为返回值
+  - 入参钳制：max_turns 为 0/None 回退默认 10，负数钳制下限 1
+  - 超限不置 conversation_active=False（收尾保留完整上下文，aibox.py 763-765 注释）
+  - 收尾失败兜底链：最后一条 assistant 消息 → "子代理未产生有效对话内容。"
+  - SubAgentTool.execute 的 max_turns 参数透传（默认 10）

----
-
-## 1. 问题陈述
-
-闭环评估（R4）暴露：z-score 归一化把 18 列方差拉平，隐式实现"全列等权"，导致**舵机精度 ↔ spk.F 频率跟踪的权衡**——未归一化模型舵机准但 spk.F 崩（21k MSE），归一化模型 spk.F 改善 3× 但简单动作恶化 1.3-25×。
-
-本质：**缩放方式（数值稳定性）与列重要性（优化方向）是两个正交维度**，当前被隐式耦合。方案目标：固定物理范围归一化（数值稳定、免 stats 文件）+ 显式逐列权重（舵机优先），两者解耦。
-
-## 2. 方案设计
-
-### 2.1 固定物理范围 min-max 归一化（actpred 侧）
-
-位置决策：**归一化保留在 actpred 侧，pybot 继续记录原始量纲**。理由：
-
-- **raw at rest**：episode 是数据资产，原始角度/频率可复用于逆运动学、碰撞检测等分析，归一化不可逆
-- **反归一化链条**：若 pybot 侧归一化，`--loop` 执行前需反归一化，min/max 表要同时存在于 recorder 与 loop 两端；现状 `predict()` 返回原始量纲，pybot 无感知，边界更干净
-- **代码库先例**：IMU 即"pybot 记录原始、actpred `imu_norm.py` 按物理量程归一化"，动作走同一条路保持一致
-- **pybot 零依赖承诺**：归一化逻辑入 recorder 会加深 pybot 对 numpy 的依赖面
-
-固定范围常量表（新增 `actpred/action_norm.py`，类比 `imu_norm.py`）：
-
-| 列 | 物理范围 | 依据 |
-|---|---|---|
-| 0-9 舵机角 | **[0, 180]** | `pybot/hd/servo.py` `MAX_ANGLE=180.0`（校准后全行程 0-180°） |
-| 10 spk.F | [0, 5000] | `@Speaker max_f=5000` |
-| 11 spk.delay | [0, 2000] | 实用上限（脚本用 10-500ms） |
-| 12-17 保留位 | 恒 0 | 不参与归一化，损失权重 0 |
-
-min-max 映射：`x_norm = (x - lo) / (hi - lo)` → [0,1]（或映射到 [-1,1]，与 IMU 归一化输出区间一致，待实现时定）。
-
-优点：免 action_stats.npy（消除 stats 路径类 bug 的整类风险）、零状态部署、数值区间有界。风险：min-max 对离群值敏感——若真实数据某列越界，需 clamp 到 [0,1] 并告警（防御口径与 `_action_bounds` 一致）。
-
-可选细化（后续）：按各舵机 `|max|`（s1=90°、s2=180°…）分列归一化，90° 舵机能用满 [0,1]，分辨率更高；需要读取 @Servo 块的 max 列构建表。
-
-### 2.2 逐列加权损失
-
-```python
-COLUMN_WEIGHTS = np.array([
-    1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0,   # 0-9 舵机（安全关键）
-    0.2, 0.2,                                             # 10-11 spk.F / spk.delay（声音与节奏，不影响运动）
-    0.0, 0.0, 0.0, 0.0, 0.0, 0.0,                         # 12-17 保留位（恒 0，纯噪声）
-], dtype=np.float32)
-# loss = mean(w * (pred - target)^2) / mean(w)
-```
-
-实施点：
-
-- `train.py` / `pretrain_mt.py` 的 `train_one_epoch` / `validate`：MSE 处乘权重向量（权重存 DataConfig，随 checkpoint 序列化，推理端无需感知）
-- 权重可经 CLI `--column-weights` 覆盖（默认用上表）
-- 训练集/验证集用同一权重；`evaluate.py` 的逐列误差报告不受影响（报告仍按无权重口径，便于对照）
-
-### 2.3 归一化与权重的组合矩阵
-
-| 配置 | 数值稳定性 | 舵机精度 | spk.F 跟踪 | 预期适用 |
-|---|---|---|---|---|
-| raw + 等权（模型 A） | 差（loss 数百量级） | 好 | 崩 | 仅演示/对照 |
-| z-score + 等权（模型 B） | 好 | 差 | 好 | 现状 |
-| **固定范围 + 加权（本方案）** | 好 | 好 | 中（w=0.2 保留梯度） | **目标** |
-
-## 3. 配套改进（同批实施）
-
-### 3.1 R4 评估器修正（指标失效修复）
-
-1. **oob_rate 恒值列退化**：span<阈值（如 1e-3）的列不参与越界判定；或改用固定物理界（舵机 [0,180]、spk.F [0,5000]）。推荐后者——与 §2.1 常量表共用，且"越物理界"比"越经验界"更符合安全语义
-2. **error_growth 长度混叠**：按 episode 归一化后聚合（每 episode 自身首末段比值取中位数），避免短 episode 尖峰主导曲线
-
-### 3.2 R1-B rollout + scheduled sampling
-
-闭环误差累积源于 teacher forcing 训练与自预测推理的不匹配。已实现的 `--rollout-len K --ss-prob p` 直接对标：建议 `K=4, p=0.5`，与加权损失同批训练对照。
-
-### 3.3 数据扩展
-
-- **实机录制**（根本瓶颈）：dry-run 帧为噪声、IMU 全零，视觉/姿态通路无真实信号。实机 `--record` 后复跑本实验
-- 验证集 1 个 episode 选模噪声大：val_split 0.15→0.3
-- 补充站立/保持类长序列（当前 std 类仅 1-81 步）
-
-## 4. 实施步骤
-
-| 步骤 | 内容 | 产出 |
-|---|---|---|
-| 1 | 新增 `actpred/action_norm.py`：固定范围常量表 + normalize/denormalize + clamp 防御 | 独立纯 numpy 模块 + 单测 |
-| 2 | DataConfig 增 `normalize_mode`（`zscore`/`fixed_range`）与 `column_weights`；dataset/train 接入 | 训练链路支持 + 单测 |
-| 3 | `evaluate.py` oob 改物理界、error_growth 按 episode 归一化 | 评估器修正 + 单测 |
-| 4 | 训练对照：固定范围+加权 vs z-score+等权（同种子、同数据） | 模型 C/D checkpoint |
-| 5 | 复跑 R4 闭环评估，验证权衡解耦 | 对比报告 |
-
-步骤 1-3 可并行；步骤 4-5 依赖前置完成。预计步骤 1-3 改动集中在 `actpred/`（`action_norm.py` 新增、`config.py`/`dataset.py`/`train.py`/`evaluate.py` 小改），不影响 pybot 与部署链（归一化在推理端内部完成，`predict()` 输出仍为原始量纲）。
-
-## 5. 决策记录
-
-- **归一化位置**：讨论过"移入 pybot 按列 min/max 归一化"。结论：不采纳（raw at rest、反归一化链条变长、IMU 先例不一致），但采纳其"固定物理范围"内核，落在 actpred 侧常量表实现
-- **舵机范围**：±180° 为误述，实际全行程 0-180°（`servo.py MAX_ANGLE=180.0`），归一化表按 [0,180]
-- **spk.F 对数尺度**：备选未定。若加权后 spk.F 跟踪仍不足，再考虑 log 变换（频率感知是对数的，10→1000 跨两个数量级）

-## 1. 背景与动机
-
-2026-08-17 用新录制的 640×480 数据集（免 resize 训练样本）重测 HEF 推理速度：
-
-| 阶段 | 640×480 输入 | 224×224 输入（旧数据） |
-|---|---|---|
-| 端到端 predict | **52.4 ms** | 60.0 ms |
-| 预处理 | **35.9 ms** | 43.1 ms |
-| NPU run | 12.5 ms | 12.9 ms |
-| 后处理 | 0.6 ms | 0.6 ms |
-
-输入尺寸已与模型一致（resize 变 no-op），**预处理仍是端到端延迟的主导项**（68%）。
-旧基准报告（2026-08-13）已记录同类问题：1080p 采集的预处理缩放约 45ms 主导端到端延迟，
-当时通过把默认分辨率改回 640×480 缓解；本次分析证明 640×480 下 Python 端预处理
-仍有约 36ms 的优化空间——但空间比初版估计小（见 §3.4 实测）。
-
-## 2. 瓶颈分析（100 次均值分段计时）
-
-| 子步骤 | 耗时 | 说明 |
-|---|---|---|
-| `_frame_float`（3 帧） | **27.2 ms** | PIL fromarray/convert + resize（同尺寸 no-op 仍有开销）+ `(x/255-mean)/std` float 运算（92 万像素×3 通道） |
-| `create_bindings` + 帧量化绑定 | **9.1 ms** | `_bind_frames`：float 归一化帧 → `round(x/q.scale+q.zp)` 再量化回 uint8 |
-| history/pred 绑定 | 0.07 ms | 可忽略 |
-
-**关键冗余**：当前流程先做 float 归一化（`_frame_float`），随后又量化回 uint8（`_bind_frames`）——
-中间 float 帧是纯中间态，归一化与量化可以**合并为一步**。
-
-## 3. 优化方案
-
-### 3.1 主方案：合并系数乘加（纯 numpy，无新依赖）
-
-HEF 帧输入是 uint8 量化值：`q = round(((x/255 - mean)/std) / q_scale + q_zp)`。
-把 4 步运算合并为**一次乘加**（系数预计算，按通道）：
-
-```
-q = round(x * A[c] + B[c])
-A[c] = 1 / (255 * std[c] * q_scale)
-B[c] = -mean[c] / (std[c] * q_scale) + q_zp
-```
-
-- 现流程 4 次全数组运算（`/255`、`-mean`、`/std`、`/q_scale+q_zp`）→ 1 次乘加
-- 数值完全等价（实测 max_diff = 0 LSB，见 §3.4）
-- 直通模式（`_normalize_frames=False`）同理：`A=1/q_scale, B=q_zp`
-
-### 3.2 附带优化（与主方案正交）
-
-1. **免 PIL 路径**：输入已是 np.ndarray 时直接运算，跳过 `Image.fromarray/convert`
-2. **resize no-op 跳过**：`image.size == (W,H)` 时不调用 `resize()`
-3. **缓冲复用**：`np.multiply/np.add` 带 `out=` 参数，减少临时数组分配
-
-### 3.3 已实施快路径：cv2.LUT（可选依赖，无 cv2 自动回退）
-
-`cv2.LUT(img, lut)` 是 C 实现的 uint8→uint8 查表，单次遍历，无 float 中间态——
-把"归一化+量化"合并为一步。集成要点（`hailo_infer.py`）：
-
-- 惰性导入 cv2（`HAS_CV2`）；**无 cv2 或非逐帧输入布局（ncfhw/nhwc_fused）自动回退 float 路径**
-- 加载时按每帧 `quant_info` 构建 256 项表（归一化/直通两种，`_normalize_frames` 判定）
-- **OpenCV 5.0 的 cv2.LUT 只接受单通道表**（(256,3) 会断言失败），逐通道应用后 `cv2.merge`
-- 输入尺寸与模型不一致时先 PIL resize（仅此情况走 PIL）
-- 依赖安装：`opencv-python-headless`（5.0.0，清华镜像；官方源过慢）
-  - 注：本方案实测后发现**合并系数乘加（§3.1）未实施**——cv2.LUT 收益已远超，
-    避免冗余代码；§3.1 保留作为无 cv2 环境下的潜在备选
-
-### 3.4 原型实测评估（2026-08-17，100-200 次均值，640×480×3 帧）
-
-| 方案 | 3 帧耗时 | 对比现 float 28.5ms | 数值差异 |
-|---|---|---|---|
-| 现 float 路径 | 28.5 ms | 基线 | — |
-| numpy 高级索引查表 | 26.6 ms | **无加速（1.0x）** | 0 LSB |
-| 合并系数乘加 | 23.2 ms | 快 19%（-5ms） | 0 LSB |
-| **cv2.LUT（逐通道）** | **1.68 ms** | **快 15.8×** | **0 LSB** |
-
-**结论**：
-- numpy fancy indexing 的 gather 开销与逐元素 float 运算相当，查表法**无收益**
-- 纯 numpy 可达的最佳是合并乘加（-5ms），受限于 92 万像素 float32 数组的内存吞吐
-- cv2.LUT 的 C 查表把帧预处理降一个数量级，且数值完全等价（0 LSB）
-
-### 3.5 实测收益（已实施，集成后 NPU 实测）
-
-| 指标 | 优化前 | 优化后（cv2.LUT） |
-|---|---|---|
-| 帧预处理（3 帧） | 26.5 ms | **3.0 ms（分段实测含绑定）** |
-| 端到端 predict | 52.4 ms | **16.1 ms（3.3×）**（200 次均值，见测试报告） |
-| 输出一致性 | — | 与 float 路径 max_diff = **0.0000**（7 类输入 + 8 seed 随机） |
-| HEF vs torch | 0.50° | 0.30°（4 角复验 PASS） |
-| vs PyTorch CPU | 2.1× | **6.7×**（16.1 vs 107.9 ms） |
-
-闭环 10Hz（100ms 预算）占用率 52% → **16%**，20Hz 32%，30Hz（33ms）48%。
-
-> 完整验收数据见 `actpred_cv2_lut_benchmark_report_20260817.md`（测试报告）。
-
-## 4. 一致性约束（关键）
-
-- **训练侧不动**：`dataset.py` 的 `Resize+ToTensor+Normalize` 保持 float 路径——
-  合并乘加只是推理侧对"归一化+量化"的合并实现，数值等价（实测 0 LSB）
-- **三后端口径**：`predict.py`（PyTorch，float 输入不量化）、`onnx_infer.py`（ORT，float）
-  不受影响；优化仅作用于 `hailo_infer.py` 的 uint8 量化输入路径
-- **帧输入判定不变**：`_normalize_frames`（量化网格负零偏判定）决定走
-  归一化还是直通，逻辑与现状一致
-- 旧 5 输入 / 旧版单图像 HEF 布局同样适用（按各自 quant_info 算系数）
-
-## 5. 实施步骤（已完成 ✅）
-
-| 步骤 | 内容 | 状态 |
-|---|---|---|
-| 1 | `hailo_infer.py`：加载时按每帧 quant_info 构建 256 项 LUT（归一化/直通两种） | ✅ `_build_frame_luts` |
-| 2 | `predict` 的 nhwc_frames 分支走 cv2.LUT 快路径（尺寸不匹配时 PIL resize）；无 cv2 回退 float | ✅ `_frame_lut_quant` + `HAS_CV2` |
-| 3 | NPU 实测：640×480 数据集 100 次均值 | ✅ 16.0 ms（52.4 → 16.0） |
-| 4 | `_npu_test.py` 4 角 + HEF vs torch 对比复验 | ✅ PASS，0.30°（≤1° 预算） |
-| 5 | 全套单测（TestHailoPredictor 等） | ✅ 188 tests OK |
-| 6 | 依赖安装：opencv-python-headless 5.0.0（清华镜像） | ✅ venv 已装 |
-
-## 6. 风险与对策
-
-| 风险 | 对策 |
-|---|---|
-| 查表取整与 float 路径存在差异 | 实测 0 LSB（表项 float32 与现路径同精度）；NPU 输出 vs float 路径 max_diff=0，vs torch 0.30° |
-| 无 cv2 环境 | 惰性导入 + 自动回退 float 路径，行为与优化前完全一致 |
-| OpenCV 5.0 多通道 LUT 断言失败 | 逐通道单表 + `cv2.merge`（实测无性能损失） |
-| 非 nhwc_frames 布局（旧 HEF） | 仅该布局启用 cv2 路径，其余走原 float 路径 |
-| 未来输入尺寸变更 | LUT 与尺寸无关（逐像素映射）；尺寸不一致时才走 PIL resize |
-
-## 7. 决策记录
-
-- **查表法（初版核心）实测证伪**：numpy 高级索引 gather 在 Pi5 上与逐元素 float
-  运算同速（26.6 vs 28.5ms），"查表降为内存索引即快"的假设不成立——教训：
-  性能方案须原型实测，不能凭直觉估计
-- **最终方案选 cv2.LUT**：C 实现查表把帧预处理从 26.5ms 降到 1.7ms（15.8×），
-  端到端 52.4 → 16.0ms；数值 0 LSB 等价。合并系数乘加（-5ms）收益被碾压，
-  不再实施（§3.1 保留为无 cv2 环境的备选）
-- **依赖取舍**：opencv-python-headless 作为可选依赖（惰性导入 + 自动回退），
-  有 cv2 环境收益 3.3×，无 cv2 环境行为不变——收益远大于依赖成本
-- **训练侧不改**：训练用 float 归一化（增强/数值精度），推理侧查表实现——两侧
-  口径在"归一化值"层面一致，量化差异由部署链固有预算吸收（HEF vs torch 0.30° 余量充足）

----
-
-## 1. 背景与动机
-
-模型 A-E 系列实验定位到两个结构性难题：
-
-1. **尺度放大**：fixed_range 线性 min-max 下 spk.F 的 1 个归一化单位 = 5000Hz 原始量，闭环反馈中误差滚雪球（模型 C/D 发散根因之一）
-2. **精度错配**：常用值（10Hz → 0.002）挤在线性尺度的低端，[0,1] 精度预算被浪费（log_range 正在验证的对数尺度解法）
-
-多头 one-hot 是本问题的**结构性解法**：把 18 维连续回归换成 18 组独立分类头，每组输出一个 one-hot 分布。分类天然消除尺度放大（每箱等距）与物理界问题（箱只覆盖物理范围），且多列 softmax 是 NPU（Hailo）最擅长的计算形态。
-
-## 2. 方案设计
-
-### 2.1 分箱设计（每组 one-hot 的维度）
-
-| 列组 | 分箱方式 | 箱数/列 | 依据 |
-|---|---|---|---|
-| 舵机 0-9（10 列） | 均匀 **1°/箱** | 180 | 匹配数据粒度：微动作插值 0.75°/步，5° 箱会把相邻步量化进同一箱、毁掉插值结构 |
-| spk.F（10） | 对数分箱 | 32 | 频率对数感知，低端聚集；log10(1+x) 均匀切 |
-| spk.delay（11） | 对数分箱 | 32 | 同左 |
-| 保留位 12-17 | 无头 | 0 | 恒 0，不参与 |
-
-**输出总量**：10×180 + 32 + 32 = **1864 logits**（当前 18）。最后层 128→1864 ≈ 238K 参数，模型 409K → ~650K，仍属轻量。
-
-### 2.2 各层改动
-
-| 文件 | 改动 |
-|---|---|
-| `actpred/bins.py`（新增） | 分箱表 + `encode(x)→one-hot` / `decode(p)→连续值`（含对数箱）；纯 numpy，供推理/部署复用 |
-| `model.py` | PredictionHead 输出 1864 维 → reshape (B, 18, bins) → 逐组 softmax |
-| `dataset.py` | target 从 (B,18) 连续值 → 每组 one-hot；**软标签**：真值高斯扩散到 ±1-2 箱 |
-| `train.py` | 损失 = Σ 列权重 × CE(组输出, one-hot 真值)；列权重沿用 default_column_weights |
-| `predict.py` | 输出 decode：**期望值** `Σ pᵢ·箱中心`（推荐）或 argmax 箱中心 → 18 维原始量纲 |
-| `evaluate.py` | 无感——predict 返回仍是 18 维原始量纲 |
-| `export_deploy` / Hailo | 多组 softmax 为 NPU 友好形态 |
-
-### 2.3 解码策略（执行时如何取连续值）
-
-| 方式 | 行为 | 评估 |
-|---|---|---|
-| **期望值**（推荐） | `Σ pᵢ × 箱中心` | 平滑连续，分辨率超越箱宽（1° 箱可出 46.4°）；单峰假设 |
-| argmax | 取最大概率箱中心 | 确定性，量化到 1° |
-| 按分布采样 | 随机抽箱 | 探索用，后续离线 RL 可复用 |
-
-## 3. 关键决策点与理由
-
-1. **舵机 1°/箱而非 5°/箱**：录制数据的微动作插值粒度为 0.75°，箱宽必须匹配数据粒度；5° 箱会把 45.0°/45.75° 压进同一箱，模型学不到特意录制的插值结构
-2. **软标签**：804 样本对 1864 logits 偏少，多数箱极少被访问。真值 one-hot 高斯扩散到邻近箱，未访问箱也能获得梯度
-3. **期望值解码补序数信息**：one-hot 丢失"45° 和 46° 相邻"先验，期望值解码在推理端部分恢复；训练端靠软标签缓解
-4. **pybot 契约零变化**：predict 输出仍是 18 维原始量纲，闭环与录制数据无感知
-5. **与现有归一化链路的兼容**：one-hot 方案独立于 zscore/fixed_range/log_range——分箱编码替代归一化，不叠加使用
-
-## 4. 实施步骤
-
-| 步骤 | 内容 | 产出 |
-|---|---|---|
-| 1 | `bins.py`：分箱表 + encode/decode + 对数箱 + 软标签工具 | 独立纯 numpy 模块 + 单测 |
-| 2 | `dataset.py`：目标 one-hot 化（软标签可开关） | 数据链路 + 单测 |
-| 3 | `model.py` + `train.py`：多头 softmax + 加权 CE | 模型与训练 + 单测 |
-| 4 | `predict.py`：期望值/argmax 解码集成 + 冒烟 | 推理链路 + 单测 |
-| 5 | 训练模型 F，与 A-E 闭环五方对比 | 对比报告 |
-
-## 5. 与其他方案的定位
-
-- **模型 E（log_range）正在训练**：若对数尺度已解决精度错配与闭环发散，one-hot 降级为可选优化（分类头天然有界、免归一化常量表的优势仍在）
-- 若 E 仍失败：one-hot 是下一个强候选（结构性消除尺度放大）
-- **互补关系**：one-hot 方案与逐列权重、R1-B rollout 正交，可叠加（rollout 治 exposure bias 的结论不变，任何损失形式都需要它）
-
-## 6. 决策记录
-
-- **箱宽**：初拟 5°/箱（保守，顾虑数据量），讨论后定为 1°/箱——数据插值粒度 0.75° 决定箱宽下限；spk 两列对数 32 箱
-- **单头多选 vs 多头单选**：softmax 单头在数学上是单选择分布；"多组 one-hot" = 18 个独立 softmax 头并行，每列一个选择
-- **多峰分布**：当前数据单峰为主，期望值解码够用；若未来出现双峰（如跨脚本姿态冲突），升级为逐箱 sigmoid 或 MDN

-# actpred 训练时安全图像增强
-
-> 文档类型：特性报告
-> 模块：actpred
-> 日期：2026-08-13
-
----
-
-## 1. 背景
-
-pybot dry-run 录制的 episode 数据样本量有限（11 个脚本 → 12 个 episode → ~728 样本），训练容易过拟合。直接增大数据集需要更多 `.mt` 脚本或更多轮次录制，成本较高。
-
-图像增强（data augmentation）是低成本扩充样本的标准手段，但机器人动作预测场景有特殊约束：**空间变换（翻转/旋转/裁剪）会改变图像的语义坐标，而动作标签未随之变换，导致训练对错误**。例如水平翻转后，左右舵机角度应互换，但标签不变，形成错误训练信号。
-
-## 2. 方案
-
-### 2.1 增强范围
-
-仅启用**颜色空间变换**（ColorJitter），不涉及任何空间变换：
-
-| 变换 | 参数 | 说明 |
-|------|------|------|
-| 亮度 | `±20%`（factor ∈ [0.8, 1.2]） | 模拟不同光照条件 |
-| 对比度 | `±20%`（factor ∈ [0.8, 1.2]） | 模拟不同摄像头增益 |
-| 饱和度 | `±20%`（factor ∈ [0.8, 1.2]） | 模拟不同色温环境 |
-| 色调 | `±5%`（factor ∈ [-0.05, 0.05]） | 轻微色偏，避免模型过依赖颜色 |
-
-**不使用的变换**（因需同步变换动作标签）：
-
-| 变换 | 原因 |
-|------|------|
-| 水平/垂直翻转 | 左右舵机角度需互换，否则标签错误 |
-| 旋转 | 重力方向变化，姿态语义改变 |
-| 裁剪/平移 | 视野变化导致动作-画面对应关系改变 |
-| 透视变换 | 改变空间关系 |
-
-### 2.2 同一样本内帧间参数一致性
-
-一个训练样本包含 `frame_len` 帧连续图像（默认 3 帧，间隔 10ms）。真实场景中连续帧的光照条件不变，因此**同一样本内所有帧共享同一组增强参数**，而非每帧独立随机：
-
-```python
-if self.augment:
-    bf = random.uniform(0.8, 1.2)   # 亮度因子，所有帧共用
-    cf = random.uniform(0.8, 1.2)   # 对比度因子
-    sf = random.uniform(0.8, 1.2)   # 饱和度因子
-    hf = random.uniform(-0.05, 0.05) # 色调因子
-for p in image_paths:
-    image = Image.open(p).convert("RGB")
-    if self.augment:
-        image = TF.adjust_brightness(image, bf)
-        image = TF.adjust_contrast(image, cf)
-        image = TF.adjust_saturation(image, sf)
-        image = TF.adjust_hue(image, hf)
-    frames.append(self.transform(image))
-```
-
-不同样本（不同 `__getitem__` 调用）使用独立随机参数，保证整个数据集的增强多样性。
-
-### 2.3 自适应 frame_len
-
-增强逻辑在 `for p in image_paths` 循环前生成参数、循环内逐帧施加。`image_paths` 的长度由 `frame_len` 决定（`image_files[t - frame_len + 1 : t + 1]`），循环自动适配。**`frame_len` 为 1、2、3、5、10 等任意值时均无需修改代码**。
-
-### 2.4 训练/验证隔离
-
-| 数据集 | 增强 | 说明 |
-|--------|------|------|
-| 训练集 | `augment=cfg.train.augment` | CLI `--augment` 控制 |
-| 验证集 | `augment=False`（默认） | 验证 loss 反映真实分布表现 |
-
-推理端（`predict.py` / `onnx_infer.py` / `hailo_infer.py`）不涉及增强，使用原始图像。
-
-## 3. CLI 接口
-
-```bash
-# 训练时启用图像增强
-bash _run.sh train --data-dir ./data --epochs 100 --augment
-
-# 显式关闭（默认关闭）
-bash _run.sh train --data-dir ./data --epochs 100 --no-augment
-```
-
-`--augment` 使用 `BooleanOptionalAction`，支持 `--augment` / `--no-augment` 双向开关。
-
-## 4. 验证
-
-### 4.1 功能验证
-
-```
-dataset size: 728 samples
-augment diff (should be >0): 0.3767        # 增强前后图像有差异
-two augment calls diff (should be >0): 0.2626  # 两次增强参数不同（随机性）
-action_history diff (should be 0): 0.0     # 动作标签不受影响
-target diff (should be 0): 0.0
-```
-
-### 4.2 端到端训练
-
-`--augment --epochs 3`（64×64，batch=8）训练正常完成，loss 正常下降。
-
-### 4.3 回归测试
-
-全量单测 90/90 通过，无回归。

-| `actpred/dataset.py` | `ActionDataset` 新增 `augment` 参数；`__getitem__` 在 Resize 前施加 ColorJitter（`torchvision.transforms.functional`） |
-| `actpred/config.py` | `TrainConfig` 新增 `augment: bool = False`；`build_argparser` 新增 `--augment`；`apply_overrides` 新增映射 |
-| `actpred/train.py` | 训练集构造传 `augment=cfg.train.augment`，验证集默认不增强 |

-- **空间增强（需同步标签变换）**：水平翻转时自动交换左右舵机角度（s1↔s2, s3↔s4, s5↔s6, s7↔s8），可将训练数据量翻倍。需要了解舵机配对关系后实现。
-- **动作噪声增强**：`pretrain_mt.py` 已支持 `--noise-std`，`train.py` 可同样引入，对 action_history 和 target 施加高斯扰动。
-- **更多 `.mt` 脚本**：从根本上扩大动作多样性，是提升模型泛化能力的最有效手段。
