Enum AttributionClass 

pub enum AttributionClass {
    Input,
    Resource,
    Environment,
    Internal,
}

Whose problem a failure is. Declared at the error’s DEFINITION site, carried structurally through every hop.

Variants

Input

Deterministic on the INPUT (context overflow, invalid request, unsupported format). The user’s to fix; retrying can never succeed — tasks failing with this class are marked permanently failed.

Resource

A compute resource was exhausted (GPU VRAM, host memory). Often transient (another process holding memory) — retryable.

Environment

The environment failed (network, registry, model download/integrity, cartridge process death). Transient by nature — retryable.

Internal

Everything else: a defect in the engine or a cartridge. Ours, said plainly. Retryable (races un-race), but never blamed on the user.

Implementations

impl AttributionClass

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

The wire token — used in the ERR frame meta, the machine_runs columns, the gRPC proto, and the loom. One vocabulary everywhere.

pub fn from_wire(token: &str) -> Option<AttributionClass>

Parse a wire token. Callers must reject None as a protocol error.

pub fn is_permanent(&self) -> bool

Whether retrying can NEVER succeed: the failure is a deterministic function of the input. Resource/environment/internal stay retryable (memory frees up, networks recover, races un-race).
