// TestDegradeStubMetadataSchema pins the #1764 stub-metadata degrade path.
// The clean tree embeds only the empty meta_data_default.json stub
// (internal/registry/catalog.go's SchemaCatalog falls through to
// RuntimeCatalog when EmbeddedServicesTyped() is empty), and run()'s isolated
// environment disables the remote overlay fetch and points the cache dir at
// an empty tmp dir, so cmd/schema/schema.go's runSchema sees
// catalog.Services() == 0 unconditionally -- the exact "offline with a cold
// cache, remote meta off" branch documented at cmd/schema/schema.go:96-101.

// cached"}}

// error with an actionable hint, NOT the raw Go panic crash that

// genuinely broken plugin, and NOT an "Unknown"-shaped internal error.
// Note: exit==2 alone does not prove "not a crash" -- a genuine Go panic also
