@nomicore/instance

Cordis service providing the immutable local Nomicore instanceId and static role (hub or peer). Both fields are restart-only and are configured once by the composition root.

createInstancePlugin(overrides?) merges defined factory overrides over its host configuration, strictly rejects unknown keys, validates the final merged configuration, and publishes ctx.nomicoreInstance. Fiber disposal revokes the service.

import { Context } from '@deepseek-ai/cordis'
import { createInstancePlugin, requireNomicoreInstance } from '@nomicore/instance'

const ctx = new Context()
createInstancePlugin().apply(ctx, { instanceId: 'peer-west-1', role: 'peer' })
const instance = requireNomicoreInstance(ctx)
