0x0 Standard Library Modules

The standalone stdlib package is ordinary 0x0 source, has its own README and

smoke test, and is published through the public library registry metadata.

This document is the public 0x0 standard-library module reference.

Package Surface

• Source: libs/stdlib/src/lib.0x0
• Smoke test: libs/stdlib/tests/smoke.0x0
• README: libs/stdlib/README.html
• Registry page: site/libs/stdlib.html
• Registry row: libs/registry.tsv
• Alias row: libs/aliases.tsv

The package exposes 63 documented public functions. Every public function uses

the normal kebab-case naming policy and has a source doc annotation.

Covered Module Families

The module coverage matrix is libs/stdlib/modules.tsv. It covers:

• language core: option, result, list, set, dict, state,

matcher, effect, protocol, and intent;

• runtime effects: io, local, net, process, random, time,

secret, and ffi;

• systems support: bit, float, measure, probe, limiter, schedule,

worker, supervisor, actor, actor_test, and workspace;

• domain support: audit and compliance.

Runtime Boundary

Runtime-effect families expose explicit request descriptors. They do not hide

filesystem, network, subprocess, random, time, or secret effects inside pure

helpers. Programs that perform those effects still use the production host

runtime capabilities documented in docs/runtime-production-capabilities.html.

This keeps stdlib helpers importable and testable as standalone library source

while preserving capability enforcement at the runtime boundary.

Verification

Use the bounded gate:

make stdlib-parity-check

The gate validates:

• all required module rows are present and current;
• each row points at libs/stdlib/src/lib.0x0;
• every required module prefix exists in source;
• public function and doc counts match;
• registry, alias, README, and package page metadata exists;
• docs/api-cross-reference.html and the support matrix describe the same

standard-library module boundary;

• libs/stdlib/tests/smoke.0x0 and an all-module generated fixture run through

the VM runtime.
