feat: align frontend estimator with backend sweep redesign#145
Merged
Conversation
Frontend miles formula now mirrors the new upfront-awarding backend (mev-commit/fastswap-sweep-redesign): replaces the `sweepMultiplier` bandaid with an additive per-token sweep overhead term that matches backend's `costEstimator` SQL exactly (14d window, p25 with p75 low-data fallback, ETH-input filter). Bid cost moves to Edge Config alongside surplus rate, and the cron bumps to hourly for gas-regime reactivity. - `use-estimated-miles.ts`: `net = surplus - bid - userGas - sweepOverhead` (additive); new `outputTokenAddress` prop drives per-token lookup - `use-miles-estimate-config.ts` (renamed from use-surplus-rate.ts): bundles surplusRate + bidCostEth in one fetch - Cron writes `miles_estimate_sweep_overhead_eth_by_token` (JSON map) and `miles_estimate_bid_cost_eth` (scalar). Map's `default` = 0.001 ETH mirrors backend's `costEstimateLastResort` - Bid-cost query window 7d for gas reactivity; sweep-overhead 14d matches backend - Cron daily -> hourly so frontend lags backend by ~1h max during gas regime changes (Alchemy budget impact negligible) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
