# LDC-E1372 — Explicit ID differs from the derived ID

The compiler warns when `@id` on a declaration whose ID is currently derived
would be ignored. An annotation equal to the derived ID stays silent.
This covers source, edition, fragment, publication, reference, entity, record,
alias type, relation, constraint, presumption, function, decision,
counterfactual, closure, procedure, stage, map, evidence policy, deadline
policy, temporal resolution policy, event, action and named query.
Nested interpretation constraints and presumptions use their scoped derived ID.

The warning preserves the existing ID algorithm and does not enable ID
replacement for these kinds. Remove the divergent annotation or use the
actual derived ID. This boundary is separate from whether the declaration
itself is executable (SPEC [§21](https://github.com/arxohq/law/blob/master/spec/SPEC.ru/05-part-v-lexis-and-basic-syntax.ru.md#21-единицы-и-деньги)).
