Enum FrontDoor 

pub enum FrontDoor {
    BucketDirect,
    Worker,
    Passway,
}

Which front door actually serves a domain’s requests (R594-F12).

Every domain manifest must say this out loud. Before it existed the difference between “R2 serves this hostname directly” and “a Worker serves it” was expressed only by whether the file happened to carry [[routes]] — so binding a route-carrying domain straight to R2 was accepted silently and served 200s on its SSG half while losing clean URLs, SPA shell fallback, deferred-route pointers and branded error pages. All of those live in the Worker (oss/mesofact/packages/mesofact-edge/src/router.ts) or in mesofact-serve; an R2 custom domain has none of them.

The vocabulary mirrors scripts/cf-apex-mode.sh (worker | grey | orange) — this moves the choice into the config where it can be checked instead of living in one bash script.

A front door does fan-in only. The render cube (SSG / SPA / SSR / deferred / 404) is mesofact’s manifest, not this one — see W173 and .yah/docs/working/W267-sovereign-public-ingress.md §“Two front doors, one render contract”.

Variants

BucketDirect

Cloudflare R2 custom domain. Requests hit R2 objects with edge caching and nothing else — no clean URLs, no SPA fallback, no branded errors. Correct for a pure asset tier (W175’s verdict for cdn.yah.dev) and wrong for anything that renders pages. Implies zero [[routes]] and no worker_bundle_path.

Worker

Cloudflare Worker generated from this manifest’s route table.

Passway

Sovereign L7 ingress — the passway proxy on yah-owned metal (oss/passway, W267). Same route table as worker; different machine terminates TLS.

Implementations

impl FrontDoor

pub fn is_route_driven(self) -> bool

Whether this front door consumes the manifest’s [[routes]] table. bucket-direct does not; the other two are nothing without it.

pub fn as_str(self) -> &'static str

The manifest spelling, for error messages.
