Nishi Compare -- Frontier Radar: Messaging & Comms Platform

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: 2869896 bytes. Generated by nx_swcompare_gapmap over a data-only domain spec (comms.q + comms.axes) — zero domain-specific code.

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

Bot / programmable platform — frontier momentum 240
Metadata privacy (sealed sender) — frontier momentum 90
Multi-device sync — frontier momentum 72
Channels / broadcast — frontier momentum 28
Post-quantum hybrid key exchange — frontier momentum 26
Ratcheting group E2EE (MLS-class) — frontier momentum 7
Message history / offline delivery — frontier momentum 3

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.
