# Normalize hosts-file serialization
The parser models Host Entries plus header and footer comments rather than the
file's exact byte layout. Serialization deliberately aligns fields, groups
comments, omits original blank-line placement, and ensures the management header
is present. This trades lossless round trips for a stable, readable output; code
and documentation must not promise preservation of original formatting.
