nx_bam_file_compose_test.nx

nx_bam_file_compose_test.nx -- end-to-end .bam stream composition. Validates the full BAM-on-disk loop: nx_bam_write_record -> binary record bytes nx_bgzf_write_stored_block -> wrapped as a BGZF block nx_bgzf_eof_marker -> appended as the spec-required terminator nx_gzip_inflate -> inflate the BGZF block back inflated bytes equal the original binary record byte-for-byte This is the substrate-honesty audit smoke for G6.0d + G6.0e: individual KATs already verify each primitive in isolation; this one verifies the composition contract that real BAM files require. Composes against the canonical "r1" / 3M / ACG / qual=[37,37,37] record from nx_bam_test.nx Section D so the byte-exact reference payload is known (48 bytes). expect_exit: 0 license_tier: ORIGINAL
