feat(rust): scaffold workspace + parity harness (phase-0)
Bootstrap the Rust port of Headroom. Additive only — no existing Python
code modified. Ships the workshop, not the widgets.
Layout
Cargo.toml (workspace) + rust-toolchain.toml
crates/headroom-core — transform library, stub only
crates/headroom-proxy — axum binary, /healthz only
crates/headroom-py — PyO3 cdylib, exposes headroom._core.hello()
crates/headroom-parity — Rust-vs-Python oracle harness + parity-run CLI
Tooling
Makefile: test, test-parity, bench, build-proxy, build-wheel, fmt, lint
.github/workflows/rust.yml: test, wheels (linux/mac), audit, parity-nightly
deny.toml for cargo-deny
Parity corpus
tests/parity/recorder.py + scripts/record_fixtures.py
125 recorded fixtures across 5 leaf transforms (ccr, tokenizer,
log_compressor, diff_compressor, cache_aligner)
Docs
RUST_DEV.md — developer setup and workspace reference
docs/spec/022-rust-migration.md — migration plan and stage breakdown
.gitignore: whitelist scripts/record_fixtures.py; ignore target/
