// fieldProvenanceInitializer is the packs package's field-provenance init port.
// RegisterRuntimeMetadataForPacks / RegisterL0RuntimeMetadata call this port
// instead of the internal/bootstrap functions directly, so the behavioral
// dependency is inverted: the concrete implementation is constructed and
// injected at the composition roots (pkg/serverruntime, internal/setupcmd, packs
// test wiring) via SetFieldProvenanceInitializer — never defaulted here. The
// packs package no longer references internal/bootstrap; the concrete impl is
// owned by the backend-side wiring entrypoint
// (serverruntime.WireControlplaneSeams).
//
// Mandatory injection: every entry point that runs a register call site MUST
// wire this port first, or it is nil.

// the bootstrap implementation and inject it here so the concrete dependency is
// owned by the composition root rather than the runtime-metadata register path.
