Function link_declared_tests 

pub fn link_declared_tests(
    tests: &[DeclaredTestCase],
    boundaries: &[HttpBoundary],
) -> Result<Vec<Edge>, LinkError>

Links declared tests to exact HTTP providers with bilateral evidence.

Tests with no observed provider remain unlinked instead of inventing a target.

Duplicate providers remain fail-closed for compatibility. Use link_declared_tests_with_ambiguities to preserve ambiguities as data while continuing with unrelated contracts.

Errors

Returns LinkError::AmbiguousProvider instead of silently omitting an ambiguous relationship.
