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.
