# named test that did not run, OpenAPI or dist drift, a hygiene violation or
# an evidence gap. --self-test proves each detector fails closed.

# TestMigrateSeedsCanonicalGenres and TestSchemaMatchesPHPSnapshot since
# Phase 9 (.planning/phases/10-admin-vue-spa/deferred-items.md). The --go
# stage accepts exactly those two failures in exactly that package, prints
