Miggo AIRoot Cause Analysis

The vulnerability stemmed from incorrect handling of the ecdsa_ptr signature builtin reference. The pre-patch code in library.cairo's execute function created a local ecdsa_ptr via alloc() (line 203 in v0.2.0), which StarkNet's runtime rejected as it expects signature validation to use the system-provided ecdsa_ptr. The patch in 2cd6027 added ecdsa_ptr as an implicit parameter to execute and _unsafe_execute, resolving the validation failure. The vulnerable functions directly handled signature validation with improper pointer management, making them root causes of the transaction processing failure on Goerli.
