Replace the MinerU client with Alibaba Cloud Document Mind (docmind) as the backing service for pdf_to_md_bundle. Aliyun docmind covers both PDF→MD (with LaTeX formula enhancement) and audio/video→text in one provider, unlike MinerU which only does documents. Changes: - Install @alicloud/docmind-api20220711 + @alicloud/credentials + tea-util - Delete mineruClient.ts; add docmindClient.ts with AliyunDocmindClient using the official SDK (SubmitDocParserJobAdvance → poll → GetDocParserResult) - CapabilitySecretPayload: baseUrl+apiToken → accessKeyId+accessKeySecret+endpoint - pdfToMdBundle adapter: provider aliyun_docmind, DocmindClientError - Tests updated: 7/7 green, mock client matches new interface Pricing (aliyun docmind, 2025-07): - PDF 增强链路 (含公式 LaTeX): 0.04元/页 ≈ $0.0056/页 - 视频: 0.002元/秒 - 音频: 0.00035元/秒 Cost is derived from page count × unit price (COST_PER_PAGE_USD) until the service reports an actual cost field; costSource=provider_reported. The aliyun CLI is NOT used at runtime — Hub calls the SDK directly. The CLI remains available for operators to manage AccessKeys and test connectivity.
