soft3

developer experience layer for the [[soft3]] stack. makes the 14-repo stack accessible without understanding every repo.

what it provides

component	purpose	status
js/	JavaScript/TypeScript SDK (current Bostrom chain)	active
schema/	canonical wire format definitions	draft
cli/	soft3 command-line tool	scaffold
mcp/	MCP server — cybergraph tools for AI assistants	scaffold
py/	Python SDK	scaffold

core operations

every SDK exposes the same five operations regardless of language:

particle(content)              → particle     hemera hash of bytes
cyberlink(from, to, neuron)    → signal       construct + sign a cyberlink
query(particle, dimension)     → value+proof  BBG Lens opening
verify(root, proof)            → bool         proof verification
submit(signal)                 → receipt      send signal to network

quick start (JS)

import { CyberClient } from '@cybercongress/cyber-js'

const client = await CyberClient.connect('https://rpc.bostrom.cybernode.ai')
const result = await client.rank.search('cyber')

status

dependencies not yet stabilised — full implementation blocked on:

• wire format finalisation (schema/)
• BBG proof serialisation (lens Commitment/Opening serde)
• query RPC protocol definition

scaffold is in place. implementations land per component as deps stabilise.

see [[soft3]] for the full stack description.
