Local-first A-share research workbench for DeepSeek Harness: market dashboards, watchlists, valuation, four investor agents, versioned reports, and continuous post-report chat.

Talk to Excel in DeepSeek Harness: read, edit, clean and report on spreadsheets by conversation. Re-checks every formula after each edit, repairs silent errors, and needs no local Excel for the core work (charts and PDF export use Windows Excel).
