SIFR-META-0001: Package const specialization reported a fatal issue. - Sifr

SIFR-META-0001 belongs to the Package metaprogramming diagnostic family. It means: package const specialization reported a fatal issue.

Why It Happens

Deterministic package specialization either reported a bounded issue or declared issue data that does not match its compiler-checked template. Fix the static schema input or the package issue declaration named by the diagnostic.

Use sifr --explain SIFR-META-0001 locally to see the renderer’s exact message template and any machine-applicable suggestions for the compiler version you are running.

Erroneous Code

@const_specialize
def describe[T]() -> ConstSpecializationOutcome[str]:
    return fatal("shape.unsupported", {"kind": "callable"})

How To Fix It

Use a type supported by the specializing package, or change the static declaration that caused the package-owned fatal issue. The package reason code and bounded arguments explain the rejected contract.

Fixed Code

@const_specialize
def describe[T]() -> ConstSpecializationOutcome[str]:
    return produced("supported-shape")
