Corona = rank-1 Pulsar (R_q^k specialised at k=1). Both share the lattice GPU NTT dispatcher; pulsar's gpu/ subpackage is a thin RegisterRing wrapper matching corona/gpu/. Byte-equal contract verified by TestPulsar_GPU_ByteEqual across (n,t) shapes (5,3), (7,4), (10,7) and a UseAcceleratorForce variant pinning the dispatcher at threshold=1. Decomplecting note: pulsar's FIPS 204 NTT in mldsa_lattice.go operates on [256]uint32 polynomials in 32-bit Montgomery form (q=8380417, R=2^32); the lattice/v7 dispatcher operates on []uint64 in 64-bit Montgomery form. Pulsar's NTT does not route through ring.SubRing today so the dispatcher is vacuous on pulsar's N=256 production sign path. The gpu/ subpackage mirrors corona/gpu's UseAccelerator / DisableAccelerator / RegisterRing / Stats surface verbatim so multi-primitive consumers see one opt-in. The byte-equal test is the regression guard for the v0.4 lift that widens mldsa_lattice.go to 64-bit Montgomery and routes through ring.SubRing. NIST-clean import discipline preserved. The reference package github.com/luxfi/pulsar/ref/go/pkg/pulsar carries ZERO non-test imports of lattice/v7 — go list -deps confirms only circl + golang.org/x/crypto + stdlib transitively. The gpu/ subpackage is a separate import path; reviewers compiling the reference for NIST submission with go build ./ref/go/pkg/pulsar do not pull lattice or cgo. Lattice/v7 enters the import graph only when go test runs (gpu surface tests + threshold_v03 byte-eq test); lattice is pure-Go on default builds, no cgo engaged unless -tags gpu && CGO_ENABLED=1 && Metal/CUDA link config. Threshold combine routes through lattice/v7/gpu when a batched dispatcher is engaged (UseAccelerator); single-poly dispatch threshold is set ABOVE pulsar's production ring degree N=256 (defaultThreshold=1024, same default as corona) — operators with a true batched dispatcher should lower SetThreshold via the gpu subpackage's runtime knob. Benches mirror corona/dkg2's CPU/GPU pair pattern: 5of7, 7of11, 14of21 at the v0.3 algebraic-threshold sign path. The golang.org/x/crypto bump from v0.32.0 to v0.49.0 is a transitive constraint from lattice/[email protected]; the bump is SHA3-byte-stable (FIPS 202), verified by existing TestAlgebraic_ByteValid and KAT round-trip passing post-bump.
