@opencode-compat/host-promise-v2

Shared Promise v2 aisdk host kit wired from the OCP layer.

Matches OpenCode @opencode-ai/plugin/v2/promise shape:

import {
  createPromiseV2Host,
  define,
} from "@opencode-compat/host-promise-v2"

const plugin = define({
  id: "demo",
  async setup(ctx) {
    await ctx.aisdk.sdk(async (event) => {
      // event.sdk = …
    })
    await ctx.aisdk.language(async (event) => {
      // event.language = LanguageModelV3
    })
  },
})

const host = createPromiseV2Host()
await host.register(plugin)
const { language, sdk } = await host.resolveProvider({
  providerID: "demo",
  modelID: "m1",
  package: "demo-pkg",
})

Adapter helper: wirePromiseV2() from @opencode-compat/adapter / @opencode-compat/ocp.

On MiMo/Kilo there is no native in-process aisdk emit yet — operators call resolveProvider from an external sidecar after Layer A setup. See docs/hosts/mimo.md §3 (copy-paste smoke + success criteria).

End-user Layer A / Option B install: INSTALL.md (Promise v2 still needs operator/sidecar resolveProvider on MiMo/Kilo).
