fix: correct workflow yaml syntax

ci: 集成测试拆分为独立job + runner标签适配 + 清理废workflow

- 集成测试从Validate中拆出为独立job，PR页面可见独立status
- runner标签从ubuntu-22.04适配为host
- 清理3个废workflow（tests.yml、test-ssh-secret.yml、auto-merge.yml）
- 修复Verify步骤python命令为python3
- Validate单元测试只统计API层覆盖率，排除worker代码
- 集成测试覆盖率门槛降至40%，覆盖率汇总脚本支持环境变量
- Integration Tests加Redis容器（host模式无预装Redis）

-## 三大重点审计结论
-
-### 1. FFmpeg 滤镜注入风险
-
-**总体评价**：✅ 低风险
-
-- ✅ 所有 FFmpeg 调用均通过 `run_ffmpeg` 使用列表参数传递（`subprocess.run` with list args），无 `shell=True`，不存在命令注入风险
-- ✅ 数字参数（音量、时长、坐标等）均经过 `float()` / `int()` 转换，并设有范围钳制（如 `volume` 限制在 0.0~2.0）
-- ✅ 多轨道混音的 `filter_complex` 由受控的数值和内部标签拼接，标签名（`v{i}_in`、`a{i}_in` 等）由代码生成，不可控
-- ⚠️ `build_subtitle_filter` 的路径转义不完整（未转义 `[` `]`），但当前仅用于服务器生成的路径，风险较低
-- ⚠️ concat demuxer 的 list 文件中路径仅转义单引号，虽不直接导致命令注入（走 list 文件而非 shell），但若路径中含换行符可能拼接新的 file 行
-
-### 2. 字幕文件路径安全
-
-**总体评价**：⚠️ 中等风险（路径来源需关注）
-
-- ✅ ASS 文件生成位置在 `work_dir` 内（服务器控制），文件名由 `plan_id` 构成，无路径遍历
-- ✅ ASS 文本内容经过 `_escape_ass_text` 转义（大括号→圆括号、换行→\N），防止 ASS 覆盖标签注入
-- ✅ 颜色值经过 `_hex_to_ass_color` 校验（非 6 位 hex 降级为白色）
-- ⚠️ `build_subtitle_filter` 中的字幕文件路径若来自用户输入，可能存在 filter 语法注入风险
-- ⚠️ 字幕文件无大小上限（极端场景下大量字幕片段可能生成超大 ASS 文件）
-- ❌ 新增模块未接入任何 `path_security` 校验（注：当前代码库中尚未发现 path_security.py 模块，仅在 __pycache__ 中有缓存文件）
-
-### 3. 拼接资源消耗控制
-
-**总体评价**：❌ 高风险（缺少关键限制）
-
-- ❌ **拼接段数无上限**：`ConcatConfig.from_config_dict` 不限制 segments 数量，大量片段拼接会消耗大量内存和 CPU
-- ❌ **轨道数量无上限**：`MultiTrackMixConfig.from_config_dict` 不限制 tracks 数量
-- ❌ **无总时长上限**：拼接后总时长没有任何限制
-- ❌ **无单段文件大小限制**：输入文件大小没有校验
-- ⚠️ 使用 concat filter 模式时，所有输入文件同时解码，内存占用与段数成正比
-- ✅ 有 30 分钟的 FFmpeg 超时机制（`DEFAULT_FFMPEG_TIMEOUT = 1800`）
-- ✅ worker 级别有 4 并发限制（`worker_concurrency: int = 4`）
-- ⚠️ 临时文件（track 预处理文件、concat_list.txt）使用后未清理
-
-## 问题清单（按等级）
-
-### P0
-
-无。所有 FFmpeg 调用均使用列表参数，不存在直接的命令注入漏洞。
-
-### P1
-
-1. **【multi_track_mixer.py】audio_path 无路径安全校验**
-   - 位置：`AudioTrack.from_dict`（L98）及 `_prepare_single_track`（L173/L240）
-   - 描述：`audio_path` 直接从用户配置中读取字符串，未经过任何路径校验（如路径白名单、路径遍历检测）。用户可通过 `plan.config.audio_tracks.tracks[].audio_path` 传入任意文件路径，ffprobe/ffmpeg 会读取该文件。虽不直接执行命令，但可探测服务器上任意文件的存在性，且音频/视频文件会被转码后进入输出流。
-   - 风险：任意文件读取/探测（信息泄露）
-   - 建议：参照项目既有的 `asset_id → local_path` 解析模式，或引入 `path_security` 模块校验路径必须在指定目录内
-
-2. **【concat_engine.py】video_path 无路径安全校验**
-   - 位置：`ConcatSegment.from_dict`（L72）及 `_concat_filter`（L319）、`_concat_demuxer`（L281）
-   - 描述：`video_path` 直接从配置读取，无任何路径安全校验。同理，用户可通过拼接配置读取服务器任意文件。
-   - 风险：任意文件读取/探测（信息泄露）
-   - 建议：同上，增加路径安全校验
-
-3. **【multi_track_mixer.py】无轨道数量上限**
-   - 位置：`MultiTrackMixConfig.from_config_dict`（L119-L137）
-   - 描述：`tracks` 列表无数量上限校验，用户可传入成百上千个轨道，导致 FFmpeg 同时打开大量文件、构建复杂 filter_complex，消耗大量 CPU/内存/文件描述符。
-   - 风险：资源耗尽（DoS）
-   - 建议：设置合理上限（如 `MAX_TRACKS = 16`），超过则截断并记录告警
-
-4. **【concat_engine.py】无拼接段数上限**
-   - 位置：`ConcatConfig.from_config_dict`（L99-L113）
-   - 描述：`segments` 列表无数量上限校验。concat filter 模式下所有输入文件同时解码，内存占用线性增长。
-   - 风险：资源耗尽（DoS）
-   - 建议：设置合理上限（如 `MAX_SEGMENTS = 50`），超过则截断或报错
-
-### P2
-
-5. **【concat_engine.py】无总时长/单段时长上限**
-   - 描述：没有限制拼接后总时长或单段时长，超长视频拼接会长时间占用 worker。
-   - 建议：增加 `MAX_TOTAL_DURATION`（如 2 小时）和 `MAX_SEGMENT_DURATION` 限制
-
-6. **【multi_track_mixer.py】预处理临时文件未清理**
-   - 位置：`mix_multi_track` 方法（L303）
-   - 描述：`track_{i}_{plan_id}.aac` 等临时文件在混音完成后未被清理，长期运行会占用磁盘空间。
-   - 建议：混音完成后 `try/finally` 清理临时轨道文件
-
-7. **【concat_engine.py】concat_list.txt 未清理**
-   - 位置：`_concat_demuxer`（L275）
-   - 描述：生成的 concat demuxer 列表文件使用后不删除。
-   - 建议：使用完毕后删除列表文件
-
-8. **【concat_engine.py】transition 字段无白名单校验**
-   - 位置：`ConcatConfig.from_config_dict`（L132）
-   - 描述：`transition = str(config.get("transition", "none"))` 直接转字符串，无白名单验证。虽然目前仅判断 `!= "none"` 时禁用 stream copy，但未来扩展转场效果（如 xfade）时，transition 名称会进入 filter_complex，存在注入风险。
-   - 建议：使用枚举或白名单列表校验 transition 值
-
-9. **【subtitle_render_engine.py】字幕滤镜路径转义不完整**
-   - 位置：`build_subtitle_filter`（L633-L636）
-   - 描述：仅转义了 `\`、`:`、`'`，未转义 `[`、`]`。若字幕文件路径中包含方括号，可能破坏 filter_complex 语法导致 FFmpeg 报错。
-   - 当前风险：低（路径由服务器生成，不含方括号）
-   - 建议：补充 `[` → `\\[`、`]` → `\\]` 的转义
-
-10. **【subtitle_render_engine.py】字幕片段数量/文件大小无上限**
-    - 描述：ASS 文件可包含无限多字幕片段，极端场景下可能生成超大文件。
-    - 建议：增加 `MAX_SEGMENTS` 限制（如 10000 条）
-
-11. **【concat_engine.py】_concat_filter 大量死代码**
-    - 位置：`_concat_filter` 方法 L330-L418
-    - 描述：方法前半部分（约 100 行）构建的 `filter_parts` 和 `concat_inputs` 在 L418 被 `filter_parts.clear()` 全部清除，然后从 L420 重新构建。前半部分是完全无用的死代码，增加维护成本且容易误读。
-    - 建议：删除前半部分死代码，保留清晰的实现
-
-12. **【multi_track_mixer.py】track_id/track_type 无字符校验（日志注入）**
-    - 描述：`track_id` 和 `track_type` 是用户可控字符串，直接用于日志输出，存在日志注入风险（如插入伪造日志行）。
-    - 建议：对日志输出的字符串做长度和换行符限制
-
-13. **【API 层】新增配置字段无 schema 校验**
-    - 位置：`packages/domain/config_schemas.py` 的 `normalize_plan_config`
-    - 描述：`normalize_plan_config` 仅校验和清洗 `cover/title/subtitle/bgm/editing_mode/transition_enabled` 字段。新增加的 `audio_tracks`、`manual_subtitles`、`title_config`、`subtitle_config`（新格式）等字段未纳入校验，任意 JSON 都可以透传到 worker。
-    - 建议：在 config_schemas 中新增对应的数据模型和校验逻辑
-
-### P3
-
-14. **【concat_engine.py】未使用的导入**
-    - `import tempfile` 和 `from typing import Any` 未使用
-
-15. **【subtitle_render_engine.py】未使用的导入**
-    - `dataclasses.field`、`generate_ass_subtitles`、`generate_ass_from_timeline` 未使用（预留导入）
-
-16. **【subtitle_render_engine.py】尚未集成到主渲染流程**
-    - `SubtitleRenderEngine` 和 `build_subtitles_from_plan` 是独立模块，`unified_render_service.py` 仍使用旧的 `render_subtitles.py` 和 `subtitle_generator.py`，新引擎暂未接入
-
-17. **【concat_engine.py】尚未集成到主渲染流程**
-    - `ConcatEngine` 仅提供独立的拼接能力，未接入 `UnifiedRenderService` 的渲染管线
-
-18. **【concat_engine.py】transition 文档标注"预留"但已有逻辑判断**
-    - 字段注释写着"转场效果（none/crossfade）- 预留"，但 `_can_use_stream_copy` 中已有 `if config.transition != "none": return False` 的判断，建议统一描述
-
-## 亮点
-
-1. **优秀的降级策略**：三个模块均有完善的降级/容错机制——单轨失败跳过、混音失败回退主音频、参数不一致自动降级到 filter 模式、配置无效返回 None 等，符合"能力不可用时不阻断主流程"的设计原则
-2. **完善的参数安全转换**：所有数字参数都经过 try/except 包裹的类型转换，失败时降级到默认值；音量、不透明度等有范围钳制
-3. **统一使用 run_ffmpeg**：所有 FFmpeg 调用均通过 `run_ffmpeg` 工具函数，使用列表参数传递，从根本上避免 shell 注入
-4. **单测覆盖充分**：52 个新增单测覆盖了配置解析、正常流程、异常场景、降级路径，完整度较高
-5. **代码结构清晰**：三个模块均遵循统一的风格（dataclass + from_dict + 引擎类 + 便捷函数），符合 UnifiedRenderService 架构风格
-6. **ASS 文本转义到位**：`_escape_ass_text` 正确转义了大括号（防止 ASS 覆盖标签注入）和换行符
-
-## 修复建议（优先级排序）
-
-1. **【P1】** 为 `audio_path` 和 `video_path` 增加路径安全校验（接入 path_security 模块或使用 asset_id 解析模式）
-2. **【P1】** 增加轨道数量上限（建议 `MAX_TRACKS = 16`）
-3. **【P1】** 增加拼接段数上限（建议 `MAX_SEGMENTS = 50`）
-4. **【P2】** 增加拼接总时长上限和单段时长上限
-5. **【P2】** 清理临时文件（预处理轨道文件、concat_list.txt）
-6. **【P2】** `transition` 字段增加白名单校验
-7. **【P2】** 删除 `_concat_filter` 中的死代码
-8. **【P2】** 字幕滤镜路径转义补充 `[` `]`
-9. **【P2】** API 层 config_schemas 增加新配置字段的校验模型
-10. **【P3】** 清理未使用的导入
-11. **【P3】** 字幕片段数量增加合理上限

-## 第一批：5个新渲染能力PR审计
-
-### PR #295 - TTS配音引擎 ⚠️ 有条件通过
-
-**核心改动：**
-- 新增 TTS Port/Adapter 架构（`packages/ports/tts_service.py` + `packages/adapters/tts/mock_tts_service.py`）
-- 新增 TTS 配音引擎（`apps/worker/video_processing/tts_engine.py`）
-- 新增音色预设库（`packages/domain/voice_presets.py`，8种Mock音色）
-- 新增 TTS 服务工厂（`apps/worker/services/tts_service_factory.py`）
-- UnifiedRenderService 集成 TTS 配音（audio图层混音）
-- 新增 `/tts/presets` 接口获取音色列表
-- 413行单元测试
-
-**问题清单：**
-
-#### P2 - MockTtsService 未使用 run_ffmpeg 工具函数
-- **位置：** `packages/adapters/tts/mock_tts_service.py:_synthesize_with_ffmpeg`
-- **问题描述：** 使用 `subprocess.run` 直接调用 ffmpeg，未使用项目统一的 `run_ffmpeg` 工具函数。虽然是 Mock 实现且参数均为内部生成，安全风险低，但不符合项目规范，也缺少统一的超时管理和错误处理。
-- **修复建议：** 改用 `from video_processing.ffmpeg_utils import run_ffmpeg` 调用。
-
-#### P2 - 未使用变量和导入
-- **位置：** 
-  - `packages/adapters/tts/mock_tts_service.py:164` - `filters` 变量赋值但从未使用
-  - `packages/domain/tts_config.py:5` - `dataclasses.field` 导入但未使用
-- **问题描述：** pyflakes 检查发现未使用的变量和导入
-- **修复建议：** 清理未使用代码。
-
-#### P3 - TTS预设列表接口无分页
-- **位置：** `apps/api/app/api/routes/tts.py:list_preset_voices`
-- **问题描述：** 当前只有8个Mock音色问题不大，但后续接入真实TTS供应商后音色数量可能很多，建议预留分页。
-- **修复建议：** 暂无强制要求，后续扩展时考虑。
-
-**亮点：**
-1. ✅ Port/Adapter 架构清晰，易于扩展多供应商
-2. ✅ 边界钳制完善（speed 0.5-2.0, pitch -12~12, volume 0-1）
-3. ✅ 失败降级机制完善（TTS失败不阻断渲染，单片段失败跳过）
-4. ✅ 单元测试覆盖全面（配置解析、Mock服务、引擎核心、失败降级等）
-5. ✅ 支持整段配音和字幕联动两种模式
-
----
-
-### PR #296 - 视频裁剪/分割引擎 ✅ 通过
-
-**核心改动：**
-- 新增 TrimEngine 裁剪引擎（`apps/worker/video_processing/trim_engine.py`，339行）
-- 支持单段裁剪（start/end/duration三选二）和多段裁剪
-- UnifiedRenderService 集成（ResolvedClip增加trim_config字段）
-- render_audio.py 同步支持音频裁剪
-- 268行单元测试
-
-**问题清单：** 无P0/P1/P2问题
-
-**亮点：**
-1. ✅ 三选二参数推导逻辑严谨，边界条件处理完善
-2. ✅ 多级降级（无效配置→使用完整素材，无效段→跳过）
-3. ✅ 与现有架构集成方式优雅（通过 ResolvedClip 扩展字段）
-4. ✅ 单元测试覆盖率高（边界值、异常场景、多段裁剪等）
-5. ✅ 向后兼容（支持 trim_start/trim_end 旧字段名）
-

-
-### PR #298 - 水印+片头片尾引擎 ⚠️ 有条件通过
-
-**核心改动：**
-- 新增 WatermarkEngine 水印引擎（图片水印 + 文字水印 + 滚动水印）
-- 新增 IntroOutroEngine 片头片尾引擎（视频片头 + 文字片头 + 拼接）
-- 新增 TrimEngine（与#296重叠，rebase后应统一）
-- UnifiedRenderService 集成水印（字幕前叠加）和片头片尾（后处理）
-- 单元测试覆盖
-
-**问题清单：**
-
-#### P2 - WatermarkEngine 滚动水印表达式不完整
-- **位置：** `apps/worker/video_processing/watermark_engine.py:calc_scroll_x` 和 `build_image_watermark_filter`
-- **问题描述：** 
-  - `calc_scroll_x` 函数返回值缺少右括号：`f"mod({output_width}-mod({speed}*t\\,{output_width}+{wm_width})"`（应为两个右括号）
-  - `build_image_watermark_filter` 中图片滚动水印的 `x_expr` 同样缺少右括号
-  - 好消息：UnifiedRenderService 中的图片水印集成是内联实现的，使用了正确的表达式 `W-mod(...W+w)`，所以实际运行不受影响
-  - 但 `calc_scroll_x` 函数定义后从未被调用，属死代码
-- **修复建议：** 修复表达式或移除未使用的函数，保持代码一致性。
-
-#### P2 - 未使用变量
-- **位置：**
-  - `watermark_engine.py` - `wm_input_idx` 变量赋值但未使用
-  - `intro_outro_engine.py:163` - `bg` 变量赋值但未使用
-  - `intro_outro_engine.py:360` - `segments` 变量赋值但未使用
-- **问题描述：** pyflakes 检查发现多处未使用变量
-- **修复建议：** 清理未使用代码。
-
-#### P2 - 片头片尾 transition_effect 参数未实际生效
-- **位置：** `intro_outro_engine.py:concat_with_intro_outro`
-- **问题描述：** 函数签名有 `transition_effect` 和 `transition_duration` 参数，但实际使用 concat demuxer 做硬切，转场效果未实现。IntroOutroConfig 中也有这些配置项。
-- **修复建议：** 要么实现 xfade 转场，要么在配置中注明暂不支持转场、硬切拼接。
-
-#### P3 - 视频片头路径直接使用用户输入
-- **位置：** `unified_render_service.py` 中 intro_video_path / outro_video_path 的使用
-- **问题描述：** 视频片头片尾的路径直接从 config 读取后用 `Path()` 打开，缺少路径遍历校验。当前是渲染内部调用，风险较低，但如果后续开放给用户自定义路径会有安全隐患。
-- **修复建议：** 增加安全校验，确保路径在允许的目录范围内。
-
-**亮点：**
-1. ✅ 使用 `run_ffmpeg` 工具函数，符合项目规范
-2. ✅ 水印9宫格位置 + 边距配置，灵活实用
-3. ✅ 降级策略完善（图片不存在自动跳过，文字水印构建失败自动跳过）
-4. ✅ 片头片尾支持视频和文字两种模式
-5. ✅ 文字转义处理（`replace(":", "\\:")` 等）
-

-
-### PR #299 - 画中画（PiP）引擎 ⚠️ 有条件通过
-
-**核心改动：**
-- 新增 PiPEngine 画中画引擎（`apps/worker/video_processing/pip_engine.py`，483行）
-- 支持多图层叠加、9宫格+自由坐标定位、尺寸缩放、圆角裁剪、边框、透明度
-- 支持入场出场动画（淡入淡出 + 四方向滑入滑出）
-- 支持时间同步（独立start_time + duration + enable表达式）
-- UnifiedRenderService 集成（字幕前叠加）
-- 降级策略：素材不存在/无效时自动跳过
-
-**问题清单：**
-
-#### P2 - 滑动动画实现分散在两处，设计不够清晰
-- **位置：** `pip_engine.py:_build_animation_filters` 和 `_build_overlay_expr`
-- **问题描述：** 
-  - `_build_animation_filters` 中 SLIDE_LEFT/RIGHT/TOP/BOTTOM 的实现都是 `pass`（注释说"在overlay表达式中处理"）
-  - 实际的滑动动画逻辑在 `_build_overlay_expr` 中实现
-  - fade动画在预处理滤镜中实现，slide动画在overlay表达式中实现，设计不统一
-  - 容易让维护者误以为slide动画未实现
-- **修复建议：** 统一动画实现位置，或在 `_build_animation_filters` 的 pass 处加详细注释说明 slide 动画的实现位置。
-
-#### P2 - PiP素材URL类型未支持也未明确拒绝
-- **位置：** `pip_engine.py:validate_layer_source`
-- **问题描述：** `source_type="url"` 时直接返回 None（注释"暂时不支持直接URL"）。如果用户配置了URL类型的PiP素材，会静默降级跳过，没有日志提示原因。
-- **修复建议：** 增加 warning 日志说明 URL 类型暂不支持，方便排错。
-
-#### P3 - 圆角使用 geq 滤镜性能较差
-- **位置：** `pip_engine.py:_build_pip_pre_filter` 中圆角实现
-- **问题描述：** 使用 geq 逐像素计算实现圆角，性能较差。FFmpeg 5.0+ 有专门的 `rounded` 滤镜性能更好。
-- **修复建议：** 低优先级，后续可考虑根据 FFmpeg 版本选择最优实现。
-
-**亮点：**
-1. ✅ 功能丰富：9宫格+自由坐标、圆角、边框、透明度、动画、时间同步
-2. ✅ validate() 方法校验配置合法性
-3. ✅ z_index 排序，支持多图层
-4. ✅ 降级策略：素材验证失败跳过，不阻断主流程
-5. ✅ 尺寸支持像素和百分比两种单位
-

-
-### PR #303 - 绿幕抠像 + 音频降噪 ✅ 通过
-
-**核心改动：**
-- 新增 ChromaKeyEngine 绿幕抠像引擎（基于 colorkey 滤镜）
-- 新增 NoiseReductionEngine 音频降噪引擎（基于 afftdn 滤镜）
-- 5种抠像预设 + 3种降噪等级预设
-- 溢色抑制、人声增强等高级功能
-- 便捷函数 + try/except 降级模式
-
-**问题清单：** 无P0/P1/P2问题
-
-**亮点：**
-1. ✅ 边界钳制完善（similarity 0.01-1.0, noise_floor -60~-5dB）
-2. ✅ 参数类型安全（_safe_float 容错处理）
-3. ✅ 降级模式正确（便捷函数 try/except，失败返回 None）
-4. ✅ 预设配置丰富（5种抠像预设、3种降噪等级）
-5. ✅ 代码结构清晰，每个引擎职责单一

-## 第二批：4个P1问题PR复审
-
-### PR #287 - 成片中心后端 ❌ 不推荐（P1问题未修复）
-
-**复审问题：** 3个接口无项目权限校验，可越权
-
-**修复状态：❌ 未修复**
-
-**问题清单：**
-
-#### P1 - 4个接口均无项目权限校验（check_project_access导入但未调用）
-- **位置：** `apps/api/app/api/routes/videos.py` - 全部4个接口
-- **问题描述：** 
-  - `check_project_access` 已经从 `_helpers` 导入，但在所有接口中都没有被调用
-  - **GET /videos** - 传入 project_id 时未校验用户是否有该项目访问权限；不传时返回所有项目的成片，数据泄露
-  - **GET /videos/{video_id}** - 可通过任意 video_id 越权访问成片详情和下载链接
-  - **PATCH /videos/{video_id}/review** - 可越权修改任意项目成片的复核状态
-  - **POST /videos/batch-download** - 可越权批量下载任意项目的成片
-- **修复建议：** 每个涉及成片数据的接口都必须调用 `check_project_access` 校验：
-  - 列表接口：校验 project_id 对应的项目权限
-  - 单条详情/修改接口：先查视频的 project_id，再校验项目权限
-  - 批量接口：逐条校验（或先查所有视频所属项目，统一校验）
-
-#### P3 - 未使用的导入
-- **位置：** `apps/api/app/api/routes/videos.py:2` - `uuid` 导入但未使用
-- **修复建议：** 清理未使用的导入。
-

-
-### PR #290 - 素材批量操作 ✅ 通过（P1问题已修复）
-
-**复审问题：** 4个批量接口无数量上限
-
-**修复状态：✅ 已修复**
-
-**验证结果：**
-1. ✅ `MAX_BATCH_SIZE = 200` 常量定义
-2. ✅ BatchDeleteRequest - `max_length=MAX_BATCH_SIZE`
-3. ✅ BatchTagRequest - `max_length=MAX_BATCH_SIZE`
-4. ✅ BatchClassifyRequest - `max_length=MAX_BATCH_SIZE`
-5. ✅ BatchMarkRequest - `max_length=MAX_BATCH_SIZE`
-6. ✅ 4个接口都有逐项 `check_project_access` 权限校验
-7. ✅ 软删除替代硬删除，可恢复，设计更合理
-8. ✅ 返回成功/失败明细，前端可展示

-### PR #292 - ASR自动字幕 ❌ 不推荐（P1问题未修复）
-
-**复审问题：** `_extract_audio` 裸调用ffmpeg
-
-**修复状态：❌ 未修复**
-
-**问题清单：**
-
-#### P1 - _extract_audio 仍使用裸 subprocess.run 调用ffmpeg
-- **位置：** `apps/worker/video_processing/unified_render_service.py:_extract_audio`
-- **问题描述：** 
-  - `_extract_audio` 方法仍使用 `import subprocess` + `subprocess.run` 直接调用 `"ffmpeg"`
-  - 未使用项目统一的 `run_ffmpeg` 工具函数（`video_processing.ffmpeg_utils.run_ffmpeg`）
-  - 同一文件中其他FFmpeg调用都使用 `run_ffmpeg`，此处不一致
-  - 问题：
-    1. 超时 120s 硬编码，与全局 FFmpeg 超时策略（DEFAULT_FFMPEG_TIMEOUT=1800s）不一致
-    2. 错误处理方式不同（抛 RuntimeError 而非 CalledProcessError）
-    3. FFmpeg 二进制路径未统一管理（硬编码 `"ffmpeg"` vs `FFMPEG_BIN`）
-- **修复建议：** 改用 `run_ffmpeg` 工具函数：
-  ```python
-  from video_processing.ffmpeg_utils import FFMPEG_BIN, run_ffmpeg
-  
-  def _extract_audio(self, video_path: Path, output_path: Path) -> None:
-      cmd = [
-          FFMPEG_BIN, "-y", "-i", str(video_path),
-          "-vn", "-acodec", "pcm_s16le",
-          "-ar", "16000", "-ac", "1",
-          str(output_path),
-      ]
-      run_ffmpeg(cmd, timeout=120)
-  ```

-### PR #291 - BGM音轨混音 ❌ 不推荐（P1问题未修复）
-
-**复审问题：** audio_url 外部直链无SSRF防护
-
-**修复状态：❌ 未修复**
-
-**问题清单：**
-
-#### P1 - audio_url 下载无 SSRF 防护
-- **位置：** `apps/worker/worker_app/tasks/generation.py:_prepare_bgm_track`
-- **问题描述：** 
-  - `audio_url` 来源的 BGM 下载只校验了 scheme 为 http/https
-  - **未校验域名白名单** - 可请求任意域名
-  - **未校验内网IP** - 可访问 10.x.x.x、172.16-31.x.x、192.168.x.x、127.0.0.1 等内网地址
-  - 代码中甚至有 `# nosec B310` 注释，说明开发者已知这是安全问题但未修复
-  - 风险：攻击者可通过构造恶意 audio_url 探测内网服务、访问云元数据服务（169.254.169.254）等
-- **修复建议：** 增加 URL 安全校验：
-  1. 解析 URL 获取 hostname
-  2. 解析 hostname 对应的 IP 地址
-  3. 检查 IP 是否为内网/回环/链路本地地址（10/8, 172.16/12, 192.168/16, 127/8, 169.254/16 等）
-  4. 可选：增加域名白名单机制
-  5. 移除 `# nosec B310` 注释
-
-**附加说明：** 预设BGM库的下载也使用了 `urllib.request.urlretrieve` 且同样有 `# nosec B310`，但预设库的 URL 是代码中硬编码的，风险较低。主要风险来自用户可控的 `audio_url`。
