Total length should be close to the expected genome size for the species. Very small totals can indicate failed read retrieval, contamination filtering, or insufficient data.
Number of contigs describes fragmentation. Fewer contigs usually means a more contiguous assembly, although plasmids and repeats can naturally add contigs.
N50 is the contig length where half of the assembly is contained in contigs of that size or larger. Higher N50 generally means a more contiguous draft.
Coverage is read support for contigs. Very low coverage contigs are more likely to be contaminants or assembly artefacts.
Failed assembly jobs counts samples that could not be assembled. Check the logfiles and accession checks before interpreting missing samples biologically.

Genome assembly (FASTA) is the main output for downstream annotation, species identification, AMR calling, and comparative genomics.
Assembly statistics (JSON) is best for comparing many jobs programmatically.
Assembly logfiles show tool messages and are the first place to look when an assembly looks fragmented or unexpectedly small.
Accession checks (CSV) records which submitted accessions were accepted, retrieved, or failed before assembly.
