• 18 backtest materializer tests
• KOL golden fixtures: Cat Lord (11 content, 7 TradeActions), Trader Ji (15 content, 15 TradeActions)

Breaking Changes

Finer OS v0.4.0 - F1 Standardization, Topic Assembly, WeChat Intake

Highlights

• Canonical F0-F8 documentation refreshed as the only supported architecture naming system.
• Added F0 WeChat article intake with session state management, QR login handling, raw artifact persistence, SHA256 traceability, incremental sync, and ContentRecord generation.
• Added F1 StandardizationRouter plus canonical adapters for Feishu chat markdown, manual text, image OCR/layout, and PDF documents.
• Added F1.5 constrained LLM topic assembly adapter backed by DeepSeek JSON output with deterministic validation.
• Added MiMo v2.5 vision configuration paths and live multimodal validation scaffolding.
• Extended F5 canonical execution/timing contracts and independent verification documentation.
• Updated dashboard WeChat configuration UI and removed build-time Google Fonts dependency so production builds do not require font downloads.

Validation

• pytest tests/ -v: 1347 passed, 36 skipped.
• npm run build in src/finer_dashboard: passed.
• Sensitive diff scan: no real keys detected; only environment variable names/placeholders.

Notes

Live WeChat and live MiMo tests remain opt-in because they require external credentials and services. The canonical F3 -> F4 -> F5 constructor is still an active architecture follow-up; legacy direct extraction remains non-canonical.
