Struct Config 

pub struct Config {
    pub manifest: PathBuf,
    pub bind: String,
    pub workers: Option<usize>,
    pub cdn_base_url: Option<String>,
    pub fallback_dir: Option<PathBuf>,
    pub worker_entry: PathBuf,
    pub sources_config: Option<PathBuf>,
    pub session_secret_env: Option<String>,
    pub session_cookie: String,
    pub login_url: Option<String>,
    pub cache_capacity: usize,
    pub policy_delegated: Vec<RoutePolicy>,
}

Fields

manifest: PathBuf

Local path to manifest.json (required).

bind: String

Bind address for the HTTP listener.

workers: Option<usize>

Number of Bun workers to spawn (default = num_cpus / 2, min 1).

cdn_base_url: Option<String>

CDN base URL for Mode 1 redirect dispatch (e.g. https://cdn.yah.dev). When set, Mode 1 routes 302-redirect to {cdn_base_url}{path}.

fallback_dir: Option<PathBuf>

Local dist/ directory for Mode 1 fallback (when CDN is not configured).

worker_entry: PathBuf

Path to the mesofact-worker entry script (bun entrypoint).

sources_config: Option<PathBuf>

Path to mesofact.config.toml. Read for source generation tokens (cache-key input 6). Missing file → generations resolve to a placeholder.

session_secret_env: Option<String>

Env var holding the HMAC key for CookieSessionResolver. When set, Mode 2 sessions resolve from the session cookie; when unset, sessions are disabled (requires: ["user"] routes always redirect/401).

session_cookie: String

Session cookie name (default mesofact_session).

login_url: Option<String>

Login URL for requires: ["user"] routes with no session. The proxy 302s here with ?next=<original-url>. Unset → 401 instead.

cache_capacity: usize

Mode 2 LRU response-cache capacity (entries).

policy_delegated: Vec<RoutePolicy>

Assert that something in front of this process enforces a route policy this tier does not (R749-T1). Comma-separated field names as written in mesofact.routes.ts.

The proxy tier’s standing case is resilience: W181 puts retry/timeout at the always-up edge (the CF Worker reads them from SSR_RESILIENCE), and this process implements none of it. Deployed behind that Worker the policy really is enforced — by the Worker — so the deployment says so here. Run without one and the refusal is correct.

Same spelling and semantics as mesofact serve’s flag on purpose: an operator moving a workload between tiers should not have to learn a second vocabulary for the same assertion.

Implementations

impl Config

pub fn policy_support(&self) -> PolicySupport

What mesofact proxy implements, advertised (R749-T1). One place, and each line has a code site behind it:

• requires — proxy::router’s Requires::User check, the only session-aware serving path in the system.
• cache_policy — proxy::cache::ResponseCache, built in cli::proxy::run.
• concurrency — the worker pool’s per-route semaphore (packages/mesofact-worker/src/pool.ts, configured from the manifest at worker.ts’s buildRouteHandlers). W225 §2c records this row as unenforced everywhere; that is wrong, and the code above is why.
• resilience — NOT enforced. Nothing in mesofact-core reads it; W181’s only consumer is the CF Worker (packages/mesofact-edge/src/router.ts, from SSR_RESILIENCE). Delegate it when that Worker is in front.

pub fn worker_count(&self) -> usize

Trait Implementations
