CF Pages deployment API（错误码 8000111）不接受带换行的 commit message。 wrangler 默认会把 git log -1 的 subject+body 整块发过去，于是带 body 的提交 就会 deploy 失败。错误信息称"not valid UTF-8"是误导——实际拒的是换行符。 加了坑 3 完整说明 + 两种修法（手动 --commit-message "$(git log -1 --pretty=%s)" 或在项目里写 scripts/deploy.sh 封装）。错误调试速查表也补了 8000111 + 8000007。 发现来源：classics-learning 项目 deploy 时踩到，单行中文 commit 没事， 本次 commit 带了 body 才暴露。
… + voice cloning + Wanx Adds `library/dashscope/` covering the non-LLM half of Alibaba's DashScope platform (Qwen LLM is intentionally NOT in scope here — that lives in the separate `qwen` module which targets the OpenAI-compatible chat-completions front; same physical API key, different module per SPEC §0 flat-no-inheritance rule). Live verification (2026-05-17) — tier `partial` - Installed dashscope==1.25.18 in a tmp venv - DASHSCOPE_API_KEY (sk-...) sourced from ~/.trove/dashscope/credentials.json - Submitted CosyVoice v3-flash TTS task via official Python SDK (`dashscope.audio.tts_v2.SpeechSynthesizer`) with voice=longxing_v3, text="trove smoke 你好" - WebSocket connection opened to wss://dashscope.aliyuncs.com/api-ws/v1/inference - Bearer header accepted; run-task event acknowledged; task_id issued - Runtime then blocked: `task-failed` event with `error_code: "Arrearage"`, message `Access denied, please make sure your account is in good standing.` Account balance ≤ 0 - Auth + endpoint + request schema verified end to end; only the billing gate stops actual audio bytes. Same partial-tier shape as the existing kling module entry Module shape (10 Critical Constraints up front, gotchas-first) 1. Account funding gate (Arrearage discovered during smoke) 2. CosyVoice is WebSocket-only, not REST sync — debunks confusing REST-style examples in older docs which were CosyVoice v1 batch 3. Region split (China dashscope.aliyuncs.com vs intl dashscope-intl.aliyuncs.com) with misleading InvalidApiKey error 4. Auth header is `Authorization: Bearer`, NOT legacy `X-DashScope-API-Key:` (pre-2024 form rejected on v3) 5. Voice ID is model-version-locked (longxing_v3 only on v3-*; longxiaochun only on v2) 6. Character billing counts full-width punctuation; cost meter is in `usage.input_tokens` (misleading field name for a TTS product) 7. Voice cloning is free; only synthesis charges 8. Watermark setting is account-wide (console), not per-call 9. Wanx image gen uses task-poll pattern (different from CosyVoice's WebSocket pattern), same auth 10. No official Node SDK — raw WebSocket for non-Python runtimes Body sections - Setup (`pip install 'dashscope>=1.25'`) - Quickstart: CosyVoice TTS via Python SDK with usage.input_tokens inspection - Voice catalogue (representative 7 voices, generic gender/style framing, link to full 150+ list — earlier private-fork's "短剧专用 (short drama)" framing genericized) - Voice cloning recipe (VoiceEnrollmentService → custom voice_id → reuse in any SpeechSynthesizer call) - Wanx image gen example (ImageSynthesis.call, presigned 24h URL) - Raw WebSocket sketch for Node/Edge/Deno (no official SDK exists) - Cost estimation table (TTS/clone/Wanx prices, char-counting rule) - 6-row error reference incl. the Arrearage we discovered live - Cross-module pointer to `qwen` for LLM access via the same key - Source of truth (9 upstream URLs + lastmod) Library bookkeeping - 20 → 21 modules - 5 prod · 14 verified · 1 partial → 5 prod · 14 verified · 2 partial (dashscope joins kling at the partial tier) - Site module grid: dashscope added under media-generation alongside seedance / seedream / kling / fal-ai Privacy - Earlier private-fork of this module had `Moment Stream` and `ADR-0021` references in the description (maintainer's downstream project + internal architecture decision record). Both stripped before OSS commit. Description reframed around the actual user- facing scope: CosyVoice TTS + voice cloning + Wanx image gen - Pre-commit hook PRIVATE_RE scan: clean on staged diff Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Adds `library/dashscope/` covering the non-LLM half of Alibaba's DashScope platform — CosyVoice TTS, voice cloning, Wanx image gen. Qwen LLM continues to live in the separate `qwen` module (same physical API key, different module per SPEC §0).
Live verification — tier `partial`
Same tier as kling: auth + contract verified, runtime blocked by billing. `last_verified` records this faithfully.
Module highlights
10 Critical Constraints (gotchas-first per SPEC §2.1):
Sections: Setup, Python SDK quickstart, voice catalogue (representative 7 voices, generic framing, link to full 150+), voice cloning recipe, Wanx image gen example, raw WebSocket sketch for Node/Edge, cost table, 6-row error reference, cross-module pointer to `qwen`, source-of-truth URLs.
Bookkeeping
Privacy
Earlier private-fork of this module body had `Moment Stream` + `ADR-0021` references (maintainer's downstream project + internal ADR). Both stripped. Pre-commit hook scan: clean on staged diff.
