API reference lives on docs.rs, where it is generated from the code and cannot go
stale. This section maps the crate landscape so you know which crate to open. The
suite is à la carte — take one crate or all of them:

- **`lockwire`** — the umbrella crate and CLI launcher. Apache-2.0.
- **`lockwire-sec`** — the security tier: FIPS-routable cryptography, PKI and CA,
  ACME, OIDC with passkeys, secure DNS, authenticated time (NTS), signed updates,
  and tamper-evident audit with SIEM export. Apache-2.0.
- **`lockwire-ai`** — the AI-provenance tier: attested memory, training-time
  governance, and signed attribution. Business Source License 1.1: public,
  auditable source, with commercial-use terms that fund the open tiers.
- **`lockwire-ssdl`** — the SSDL tooling that enforces the development process
  described under [Evidence](/evidence/). Apache-2.0.

Each repository carries a `FEATURES.md` stating, feature by feature, what is
implemented, in progress, or planned; those files are the source of truth this
section links to rather than restates. A machine-readable feature matrix at a
stable URL is part of the site's design for AI agents — see [Agents](/agents/).

The crate names are reserved on [crates.io](https://crates.io/crates/lockwire);
the per-crate map and docs.rs links go live here as each tier publishes.
