}

A memoized, deterministic calculation failure.

Variants

Evaluation

SIM evaluation rejected the ordinary source expression.

Fields

message: String

Stable diagnostic text.

Cycle

Dynamic dependency evaluation entered a cycle.

Fields

path: Vec<CalcQuery>

Deterministic path with the repeated query at the end.

ExpressionDepth

Expression nesting exceeded the non-configurable host safety ceiling.

Fields

limit: usize

Hard ceiling.

Blocked

Effective trigger policy prevented this attempt.

Fields

path: String

Canonical blocked cell.

reason: String

Stable policy explanation.

RequiredCapability

Diminished authority did not contain a required capability.

Fields

path: String

Canonical cell requiring the capability.

capability: CapabilityName

First missing required capability in stable name order.
