Struct DomainRoute 

pub struct DomainRoute {
    pub path: String,
    pub headers: BTreeMap<String, String>,
    pub mode: RouteMode,
}

One entry in a DomainConfig’s route table.

The mode discriminator picks the variant’s body via serde’s internally-tagged enum representation. Path patterns follow the Worker convention: a trailing * matches everything underneath.

Fields

path: String

URL pattern this route matches. Examples: "/", "/dashboard/*", "/camp/ws".

headers: BTreeMap<String, String>

Response headers the front door sets on every response served under this route (R746). Empty by default.

This is the manifest’s answer to “who decides a path’s response headers”. Before it existed the answer was nobody: a _headers file is a Cloudflare Pages / Netlify convention, and neither of this repo’s front doors reads one — a Worker returns what it fetched from R2, and R2 serves only the object’s own httpMetadata. So a site could carry a _headers file declaring COOP/COEP and ship without them, which is exactly how it was found: SharedArrayBuffer is simply absent in a document served cross-origin-isolation-free, with no error anywhere to say why.

Deliberately a free-form name -> value map rather than named fields for the isolation headers: the domain manifest has no business knowing which headers a route’s payload happens to need. Ordering follows the route table’s own rule — first matching route wins, no merging across routes (see the Worker’s applyRouteHeaders).
