nyx v4.0.0-rc.1 (Official Release)

Nyx v4.0.0-rc.1 — Samsara

Nyx v4.0.0-rc.1 is the first public release candidate for the compiler-focused
v4 line. It is intended for evaluation, compatibility testing, and feedback;
it is not the v4.0.0 Nirvana stable release and does not freeze every public
API.

Highlights

• Nyx-authored lexer, parser, type checker, typed-HIR lowerer, and C++ emitter
  remain reproducible through the native stage-1 -> stage-2 -> stage-3 chain.
• Default arguments now lower consistently through the Python and self-hosted
  paths, including calls that omit trailing defaulted parameters.
• Flat array and struct destructuring is available with single-evaluation
  semantics, checked bounds/arity failures, const bindings, and hygienic
  compiler temporaries.
• The stable HIR runtime trio (cpp, js, python) retains shared typed-HIR
  semantics. Rust, WASM, React, and assembly remain governed by their explicit
  capability contracts.
• The release includes native-first installers, a local VS Code .vsix,
  deterministic source archives, checksums, an SPDX SBOM, and GitHub provenance
  attestations once the tagged workflow completes.

Scope

The Maya scope reset remains in force. Microcontroller/freestanding firmware,
board profiles, flashing, and physical HAL modules are not part of Nyx v4 RC1.
The active scope is compiler correctness, HIR parity, self-hosting, native and
WebAssembly output, readable syntax, diagnostics, and deterministic tooling.

For a reviewed installation path, download the matching release archive, inspect
the installer, verify SHA256SUMS, then run it locally.

Validation

• The unified local test framework passed completely.
• 138/138 regression battery, 530-case fuzz corpus, 194-case Python/Nyx HIR
  byte parity, default arguments, destructuring, and native self-host
  reproducibility all passed.
• The tagged GitHub Actions workflow validates the full release candidate and
  produces the platform artifacts. Treat published checksums and attestations
  from that workflow as the release evidence.
