What it does

• Routes prompts with local heuristics and an optional Claude Code fallback.
• Uses Haiku only for clearly mechanical work; defaults agentic coding to Opus with graduated effort.
• Routes Agent and Task sub-agents when they spawn. Nested delegation is floored at the implementation target, and an explicit model always wins.
• Records the requested and resolved model for completed sub-agents, so host-side fallback or allowlist substitutions are visible.
• Dampens borderline classifications instead of switching tiers on weak evidence.
