xt
Cross-target libraries, substrates, and runtime building blocks.
xt.* is the portable application layer built on hara.lang and xtalk. It contains language-common libraries, database builders, event helpers, network adapters, and substrate transports that can be emitted or exercised across runtimes.

Generic MCP descriptors plus optional substrate node kernels, clients, and proxies.
xt.net
HTTP fetch, SQL and Redis connections, websocket helpers, and Supabase integration.
xt.event
Event, route, model, form, log, validation, animation, and throttle helpers.
xt.substrate
