zena:core

zena:core — the standard library's foundation: the types the language itself is defined in terms of, and the utilities they are built from.

The library is published before it owns anything. stdlibLibraryOf attributes a file under core/ to this library only if core is a published module, and the well-known declaration registry keys on the owning library — so a declaration cannot move here until a bootstrap exists that already knows the name. Publishing it empty is how that bootstrap gets made; see docs/design/stdlib-organization.md, Phase 1.

Members arrive by moving their files under core/ and repointing their manifest entries, so each keeps its own module name for now and this facade stays empty. It gains re-exports only once the entrypoints collapse, which is Phase 3.
