Expand description
Cascade-spec error classification.
MutationErrorClass mirrors the app.mutation_error_class PostgreSQL enum
emitted by app.mutation_response rows. CascadeErrorCode is the wire
representation used by the graphql-cascade error envelope. The mapping
between them is 1:1 — no fallbacks, no HTTP-code tiebreakers.
See docs/architecture/mutation-response.md (semantics table + mapping).
