v0.19.0
HotClip v0.19.0 — 证据只算一次，下一刀更快更准
这一版把长视频分析从“一次性中间过程”变成跨任务复用、可检查、可安全清理的本地证据，同时增加无需下载新模型的运动信号。
- 本地多模态证据索引：响度、镜头、运动、TransNetV2 边界与可选视觉扫描结果按源文件指纹、能力版本和模型身份原子落盘。文件、算法或模型变化时只重建失效能力，损坏条目自动丢弃。
- 九路证据链：轻量运动峰值加入文本、响度、镜头、表情、视觉、弹幕、语气与笑声/掌声。工作台时间轴新增青色运动曲线，让非语言高能片段的依据直接可见。
- 抽帧覆盖更稳：运动峰值引导代表帧，但始终为全场均匀覆盖保留三分之一预算，避免前段热闹画面挤掉后段安静却重要的场景。
- 全入口共享：桌面、CLI、MCP、录播监听与 webhook 使用同一份 Tier-0 信号、镜头边界与可选 VLM 扫描结果；视觉 API Key 不会写入索引。
- 有界且独立：索引默认最多 64MB，按最近使用淘汰；健康检查显示占用，二次确认只清可重复生成的分析证据，不碰项目、素材、模型、转写缓存或 1GB 渲染缓存。
- 长任务可取消：信号采集与镜头检测响应取消信号，失败或缓存不可用时保持原有透明重算行为。
验证：103 个测试文件全部通过，1,061 项通过、1 项按既有条件跳过；TypeScript 双目标检查、生产构建、真实 FFmpeg 运动元数据烟测，以及中英文工作台/诊断页响应式浏览器验收均通过。
HotClip v0.19.0 — Analyze once, make every next cut faster and sharper
This release turns long-video analysis from disposable intermediate work into reusable, inspectable and safely clearable local evidence, while adding a model-free motion signal.
- Local multimodal evidence index: loudness, shots, motion, TransNetV2 boundaries and optional vision-scan outcomes are atomically keyed by source fingerprint, capability version and model identity. Changed files, detectors or models rebuild only stale capabilities; corrupt entries are discarded automatically.
- Nine-channel evidence chain: lightweight motion joins transcript, loudness, shots, facial emotion, vision, live chat, vocal tone and laughter/applause. A cyan motion curve in the workbench makes non-verbal activity evidence visible.
- Better frame coverage: motion peaks guide representative frames, while one third of the budget remains reserved for uniform full-source coverage so early spectacle cannot hide a later quiet-but-important scene.
- Shared everywhere: desktop, CLI, MCP, folder watch and webhooks reuse the same Tier-0 signals, shot boundaries and optional VLM scan outcomes. Vision API keys are never persisted in the index.
- Bounded and independent: the 64MB LRU index has its own diagnostics and two-step cleanup. Clearing it never touches projects, source media, models, transcript cache or the separate 1GB render cache.
- Cancellable long work: signal collection and shot detection honor cancellation, while missing or invalid cache entries preserve the existing transparent recompute path.
Verification: all 103 test files passed, with 1,061 passing tests and 1 existing conditional skip. Both TypeScript targets, the production build, a real FFmpeg motion-metadata smoke test, and bilingual responsive browser QA for the workbench and diagnostics passed.
