source you own registries you can host agents that prove their work

Source distribution

npx verseva init
npx verseva add button field toast console-nav
npx verseva block add quote-tool
npx verseva theme add cobalt
npx verseva list

Components land as source. Typed, dependency-free React files in your project; edit freely, reset with --force.
Blocks land as full working pages, css hrefs already pointed at node_modules; byte-locked to the live gallery by test.
Nothing ships unproven: init wires the gate script; run it before every ship.

npx verseva build
verseva build: 25 items + registry.json -> site/r

Host your own. `verseva build` flattens the registry into per-item JSON with content embedded; serve the directory anywhere static.
Namespaces. Consumers map them in verseva.json: {"registries": {"@you": "https://your.host/r/{name}.json"}} then npx verseva add @you/thing.
URLs and files too. `add` takes bare names, @ns/name, a full https URL, or a local .json item.
Contained by construction: written names flatten to basenames, symlink destinations are refused, only source extensions install, fetched items must embed content, deps stay on their item's origin, and registries are https-only.
This registry is hosted here: once design.verseva.com is live, every item resolves at design.verseva.com/r/{name}.json.

npx verseva mcp init --client claude

Tool	What the agent gets
list_registry	Everything installable
get_component / get_block	Real source, read before imitating
get_tokens / get_laws	Every allowed value; the fourteen laws
add_component	Installs source into the project, deps resolved
run_gate	Runs all four gates and returns the verdict: done means proven

The tool nobody else ships: run_gate lets the agent PROVE its output stayed on-signature before claiming it's done.
Zero dependencies. The server is one file over stdio; cursor and vscode wiring included.

One accent, matte (law 3): a preset re-values the accent axis only; structure never changes.
Every preset ships gate-proven across all four theme axes (base and brand, dark and light), and stays provable in your build.
Wire it: link after tokens.css, set <html data-brand="cobalt">.
