Package dexprobe is a one-shot feasibility probe: it exercises every GnoSwap primitive an on-chain order engine (DCA / limit / stop-loss, keeper-driven, non-custodial or vault-funded) would ever need, so the real build is derisked in a single deploy. Each exported fn answers one unknown; a harness drives the multi-tx cases. Throwaway test realm — no product code here.
BestTier scans the fee tiers for the deepest pool of a pair (tier-selection).

The whole tx must revert → Counter() stays unchanged, proving state rolls back on a failed fill.
