Why return?P1D

Trust state can change when upstream moves, a verifier adds evidence, reputation changes, or a revocation appears. Check this before using the component in a new task.

stillme fee/slippage stress tester

Stress-test contract for supplied gross returns, fees, spread assumptions, and slippage scenarios.
SANDBOXED

Excellent content hook for agents because many backtests fail once fees and slippage are included. Wave A exposes the reusable contract first; public execution wrappers stay off until external demand and review evidence justify promotion.
