# Regression check for issue #3 (gnark-crypto twisted-Edwards
# PointExtended.Add lazy-init bug). Builds wasm + native pk/vk for the
# v3 vote circuit and runs the wasm prover against the native bytes via
# the regular loadKeys path. The wasm prover applies the workaround
# (`_ = babyjubjub.GetEdwardsCurve()` at startup) so loadKeys+prove
# returns a real proof. Without that line — or without an upstream gnark-
# crypto fix — this fails with `constraint not satisfied` mid
# scalarMulFakeGLV. Requires a v3 witness dump at
# /tmp/v3-witness-dump.json (produced by `e2e/v3_dump_witness.spec.js`).
