+  # TEMPORARILY DISABLED: check-core-crypto-features
+  # Reason: serde 1.0.218+ introduces serde_core which causes duplicate panic_impl
+  # when building wasm32 with --features=serde. alloy-consensus requires serde >= 1.0.226
+  # so we cannot pin to older serde.
+  # Tracking issue: https://github.com/pezkuwichain/pezkuwi-sdk/issues/355
+  # Upstream: https://github.com/serde-rs/serde/issues (to be filed)
+  # TODO: Re-enable when serde fixes the wasm32 + no_std + serde feature combination
