STDLIB COVERAGE MATRIX

Every row below is a capability, not a bundled C library. We only count "built-in" if the language ships it without a third-party package. Go's standard library is famously wide; Rust's is famously narrow; Python's is famously old. Lateralus is written from scratch in 2025–2026 with modern workloads in mind.

◉ READ THE MATRIX

Count the solid squares in each column. Python ships a lot of old stuff (telnetlib, nntplib) but almost nothing modern. Go gets TLS and HTTP but stops well short of Arrow, OTLP, or edit distance. Rust's stdlib is famously minimalist — everything else is a crate. Node's crypto is strong but analytics is absent.

Lateralus has ~50 solid squares that Python, Go, and Rust all have zero in. That's not a coincidence — it's the niche. If your work intersects observability, analytics, or secure-by-default networking, the one-binary answer exists here.

Every tick in the Lateralus column is readable pure-Lateralus source in stdlib/. No opaque C libraries, no compiled-wheel mystery boxes. Audit every byte.
