zeekay 4e0ddde49b dexvm: pin C<->D atomic seam wire (69-byte, spent witness) against precompile golden
The swap-seam HIGH fix (c242e01) extended encodeExportedOutput to 69 bytes
(rail|owner|asset|amount|spent), where the trailing spent witness carries the matched
INPUT amount on a D->C swap proceeds leg so the C-side ImportSettlement can enforce the
taker's recorded slippage limit. That widening MUST be byte-identical with the precompile's
exportedOutputSize9999 or D would export an object C cannot decode (every swap settlement
reverts ErrNativeSettleMalformed, no taker is ever credited).

native_seam_parity_test pins the lockstep on the D side: a hardcoded golden vector
(reproduced byte-for-byte by precompile/dex/native_seam_parity_test) + a round-trip that
proves the spent witness survives + a wrong-width rejection. If either repo's layout drifts,
one of the twin parity tests fails BEFORE the bytes reach consensus. Closes the dangling
'native_seam_parity_test pins it' reference in atomic.go.

Lux Chains

Independent VM plugin binaries for the Lux Network.

Each directory builds to a standalone binary that the Lux node loads as a plugin via --plugin-dir.

Build

make            # build all VMs
make evm        # build one VM
make test       # test all

Install

lpm install evm
lpm install dexvm

Or copy binaries to ~/.lux/plugins/<vmid>.
