- NewSchemaCommand / NewMCPCommand / newCatalogCommand no longer accept a
DiscoveryCatalogLoader they always discarded; schema's no-discovery
property is now structural, retiring the panic-loader test guard along
with the trivial root.go wrappers and the unused buildMCPCommandFn seam.
- Delete the lazy sync.Once / atomic counter around the retired MCP pin:
runtimeMCPMetadata only existed so a diagnostic counter could observe a
loader that always returns the constant empty pin. Assembly now calls
emptyPinnedMCPMetadata directly and SchemaMetadataLoadCounts loses the
dead MCPMetadata field (the policy bans keep the retired names from
reappearing).
