LDC-E1206 — Context profile extension cycle

What it means

Named context profiles form a single-parent chain: each profile may extend at most one parent, and following those links must always reach an end. When two profiles extend each other — directly or through a longer loop — no evaluation order exists, so the compiler stops at the link that closes the loop.

The repair is to break the loop: drop one of the two extensions, or remove the profiles if the settings belong with the case instead. The passing file below drops the profiles and keeps the package.

Example

Arxo Law

language "law.core" version "0.2";
package demo.diagnostics version "0.1.0";
namespace "urn:law:demo:diagnostics";

context profile A extends B {
    mode active;
}
context profile B extends A {
    mode active;
}

Fix

Arxo Law

language "law.core" version "0.2";
package demo.diagnostics version "0.1.0";
namespace "urn:law:demo:diagnostics";

entity Applicant;

Engine message

The engine reports this in its own wording:

Output

example.law:5:17: error LDC-E1206: context profile extends cycle detected at "A"
