about

nx_host_router.nx -- S-class sovereign multi-site host router (pure Nishi, no TLS, no crypto). Config-driven vhost table + PER-REQUEST file serving = HOT CONTENT LOADING: push a file, it is live on the next request, NO recompile. Path-traversal-safe. This is L5 (content) of the sovereign hosting design (knowledge/research/2026-06-05-sovereign-web-hosting.md). Composed into the TLS daemon, which supplies L3/L4. license_tier: ORIGINAL
