+### Changed
+
+- **`@orbinum/circuits`** bumped `0.4.4` → `0.5.0` — adds `fee` as a public signal to `unshield` and `transfer` circuits (breaking change in circuits, semver-minor here).
+- **`src/circuits/config.ts`** — `expectedPublicSignals` updated:
+  - `Unshield`: 5 → 6 (`[merkle_root, nullifier, amount, recipient, asset_id, fee]`)
+  - `Transfer`: 5 → 7 (`[merkle_root, nullifiers[2], commitments[2], asset_id, fee]`)
+- **`tests/circuits/config.test.ts`** — expectations updated to match new signal counts.
