Standard Library Root¶

std is the canonical root module for the standard library. It is a normal module with module.toml, a version string, and a manifest-defined main .ct file. Its provider is the compiler/toolchain installation, so consumers do not list it in [dependencies].

Standard-library APIs should be organized by explicit domain namespaces exported from the std main file:

std.math
std.sort
std.mem
std.testing
std.collections
std.hash
std.fmt
std.debug
std.io
std.text

The exact module list is not fixed, but the rule is fixed: broad library facilities live under an explicit namespace. They are not prelude names.

std is available for resolution in every ordinary module:

const std = module("std")
include("module://std/main.ct")

This does not automatically bind the name std in source. Code must bind it with const std = module("std"), import it with import module("std"), or use module://std/... explicitly. Availability for resolution is separate from namespace pollution.

std is reserved. Ordinary module manifests and dependency aliases must not use std unless the toolchain is compiling its own standard-library module under toolchain build mode. Alternate standard-library replacement is future toolchain/build configuration, not V1 dependency aliasing.

std source receives the ordinary compiler-provided prelude initial scope like any other normal module. That does not make std part of the prelude.
