Nishi Compare -- Frontier Radar: NishiLang and Compiler Toolchain

Where the 2025/26 research frontier is moving, and where Nishi should test, deepen, or research next.

How this works. The nishi researcher banked the current (2024-2026) frontier for this domain over sovereign TLS (keyless OpenAlex/arXiv). For each capability axis this radar measures frontier momentum = how often the frontier corpus mentions it, times our organ presence (probed on disk). Absent + hot = a research opportunity / where to test. Corpus measured: 3196215 bytes. Generated by nx_swcompare_gapmap over a data-only domain spec (lang.q + lang.axes) — zero domain-specific code.

Top research opportunities (the 2025/26 frontier is active here and Nishi has no organ yet):

LLM-assisted compiler testing and repair — frontier momentum 145
Memory safety / ownership types — frontier momentum 40
Language server / IDE integration — frontier momentum 20
Verified compilation / translation validation — frontier momentum 11
Diagnostics / error-message quality — frontier momentum 9
Auto-vectorization — frontier momentum 8

frontier momentum is a mechanical keyword count over real 2024-2026 works; our presence is probed on disk. A discovery signal, not a ranking of importance. Zero JS, zero trackers.
