Set per-run or per-session cost budgets with automatic downgrade.\n\n## Current State\nNo cost awareness in routing. All tasks go to configured harness regardless of cost.\n\n## Target State\nCost-aware routing considers harness/model pricing. Per-run and per-session cost budgets. Automatic downgrade to cheaper model when budget nearing limit. Cost optimization suggestions.\n\n## Dependencies\n- [GAP-HADAPT-001](../harness-adaptation/GAP-HADAPT-001.md) -- capability routing foundation\n- [GAP-SESSION-004](../session-management/GAP-SESSION-004.md) -- session-level cost budgets\n\n## Key Files\n| Component | Path |\n|-----------|------|\n| Harness adapters | `packages/sdk/src/harness/` |\n| Config module | `packages/sdk/src/config/` |\n\n## Recommendation\nPhase 2 implementation. Define cost model per harness/model. Implement budget tracking. Auto-downgrade when budget threshold reached.\n",
