A runtime with an explicit extension boundary

Current release surfaces

The current immutable manifest records these boundaries:

• Millrace Core: millrace-ai is the available compiler, kernel, storage, adapters, daemon, and CLI package at version 0.22.2.
• Millrace Plus: millrace-plus 0.22.2 is published with official workflow definitions, prompt assets, stage skills, and authoring guides. It remains Preview here because broad workflow qualification is not claimed.
• Millforge: millforge 0.1.0 is published as an independently owned execution harness, with broad public qualification still outside this site's launch evidence.
• Millrace bundle: the dependency-only millrace 0.22.2 distribution is published with exact pins for millrace-ai 0.22.2, millrace-plus 0.22.2, and millforge 0.1.0; its coordinated clean-install path is not yet qualified here.
• Millrace OS: In development, with no qualified release surface in the current manifest.

The v0.22 package boundary documentation is the source for these responsibilities. The runtime stays generic; adding a workflow should add compiled data and assets, not a new kernel branch.

Separate products, linked authority

Optional tooling can make Millrace easier to author, operate, or extend, but each product must keep its own release and capability evidence. A package name or roadmap entry is not proof that a provider, UI, adapter, or assistant is available.

Use the source repository for current package code. This page deliberately does not turn planned products into present-tense features.

Experimental Rust line

The public Rust 0.5.2 implementation remains experimental. Its current README says it consolidates the Python 0.20.1 through 0.20.3 stabilization line, so this site does not present it as parity with the production Python 0.22.2 runtime.
