DSH Ultramath

Key features

• UltraMath master + 4 role presets: master self-contained full process + mathematician/engineer/writer/reviewer single-stage entry, idempotent synchronization to /.dsh/.agent-presets/ at startup.
• dsh-ultramath — UltraMath mathematical modeling competition multi-agent solution plug-in
• Phase 0Solving/Model Derivation/Framework Design.md (Core Idea/Core Quantity/Five Questions Progressive Mapping/Proposition Tree)
• The node half side synchronizes the 5 presets under presets/ idempotently to /.dsh/.agent-presets/ when the host starts (the same bytes are skipped, and the agent.cordis.yml structure is checked: missing name / name prefix is illegal / duplicate id is considered a failure).
• 33 model libraries + 93 corpus summary methodologies: skills/model library/33 method documents, and a supplementary "Abstract Writing Enhancement" (nine principles + three-stage skeleton + two-stage closed loop + 30-second reading path for review).
