+### Fee Precedence
+
+When both `fee` and `feeMultiplier` are present, `fee` wins. The precedence is:
+
+1. **`fee`** — explicit inclusion fee in stroops (e.g. `"5000"`)
+2. **`feeMultiplier`** — multiplied by `BASE_FEE` when `fee` is absent
+3. **`BASE_FEE`** — hardcoded fallback when neither is set
+
+Use `resolveFee(config)` to compute the effective fee for a given `ConduitConfig`.
