std.sx now contains only alias declarations (the re-export mechanism: own decls carry one flat-import level) over three part-files: core.sx (builtins, libc escape hatch, Source_Location/Allocator/Context/Into, the reserved `string` decl — which needs and permits no alias), fmt.sx (print/format/any_to_string/string ops/cstring/alloc_slice), list.sx (List). The namespace tail is unchanged; the part-file namespaces (core/fmt/list) carry alongside it. Consumer surface is byte-identical — every bare prelude name resolves through the aliases (0120/0121 machinery). 37 .ir snapshots re-pinned: pure string-constant renumbering from the changed import graph (digit-normalized diff is empty). Gates: zig build test 426/426, suite 588/588, m3te 23/23, game SxChess builds + bundles.
