mechanism

CVE-2026-41584 (GHSA-452v-w3gx-72wg): a V5/NU5 tx whose Orchard action rk is the IDENTITY point [0x00;32] - a canonical point the spec allows, so it passes parse + hash() - but Orchard proof verification extracts the identity's affine coords and .unwrap()s (circuit.rs Instance::to_halo2_instance) → PANIC. Single unauth P2P tx crashes the node in verify. Fixed v4.3.1 / zebra-chain 6.0.2.
