"""Unit: manifest parsing for `bottle.egress.routes[]` (PRD 0017, PRD 0053).

The route shape uses Gateway API HTTPRoute match vocabulary:
`host` (required), optional `matches` (paths/methods/headers),
optional nested `auth: { scheme, token_ref }`, optional `dlp`.
Validation rules per PRD 0017/0053: empty `auth: {}` is an error,
partial `auth` is an error, auth omission means unauthenticated."""
