cost-optimization 4

Tiered model router for DeepSeek Harness: routes auxiliary calls (session title, compaction) and subtasks to light models, escalates hard tasks to strong ones — automatically, per request, across providers.

Cut MCP context and API cost in DeepSeek Harness with two model-facing tools, lazy discovery, and exact-schema calls

Hybrid model router for DeepSeek Harness: declarative rules, user-configurable cost control (cost-first / quality-first / balanced), optional LLM task classifier, and failure fallback chains.
