Rotifer v0.2: IR Compiler & Algebra — Genes Learn to Compose

#ai #webassembly #compiler #opensource

v0.2 turns genes into first-class WASM citizens with content-addressable identity, adds true parallelism to the algebra engine, and publishes the Rust core as an independent crate.

IR Compiler Pipeline

The new rotifer-core::compiler module brings full Intermediate Representation support:

Custom WASM sections — rotifer.version, rotifer.phenotype, rotifer.constraints, rotifer.metering
Content-addressable identity — every gene gets an irHash computed via SHA-256 over its IR content. Identity is derived from what a gene is, not what it's called.
IR verifier — static validation of exports, prohibited instructions, and memory limits
5 genesis WASM genes — echo, wrap, search, summarize, translate compiled to real IR

rotifer compile --wasm   # full IR compilation with phenotype update

Algebra Parallelism

The Par operator now uses true CPU parallelism via std::thread::scope instead of sequential execution. When your genome says "run these genes in parallel," they actually run in parallel.

crates.io

rotifer-core is now published as an independent Rust crate with full rustdoc coverage on all 150+ public API items. Rust developers can build on the Rotifer type system and engines directly.

CLI Upgrades

rotifer compile — full IR compilation with --wasm flag, phenotype update, and compile-result.json output
rotifer arena watch — real-time ranking diff monitoring with summaries

Fixes

Try operator now correctly returns the primary result on success (was re-executing the primary gene)

By the Numbers

22 → 180 tests across 10 modules
New dependencies: rmp-serde, wasm-encoder, wasmparser
