oc-cost-ops

Cost operations harness — attribute LLM spend to the skill phase that incurred it, set per-phase and per-suite budgets that gate in the checkpoint, and recommend model-tier routing (Haiku for cheap repetitive phases, Opus for spec/audit/migration). Use for /oc-cost, "what did this cost", "cost attribution", "token cost", "budget gate", "model tier routing", "cost regression", "cheaper model", "spend per feature". Pairs with oc-prompt-ops (cost-regression gate alongside the score gate) and oc-telemetry-ops (feeds the public /dashboard cost stats).
