// differ from OpenCode and both matter:
//   * the file lives in MiMo's own global config directory. That is

//     and merges them in that order, so writing `config.json` — the first and
//     weakest layer — leaves a hand-written `mimocode.json` in charge.
//   * `provider.<id>.models.<id>.limit` requires BOTH `context` and `output`
//     in MiMo's schema, the same as OpenCode's (https://opencode.ai/config.json).
// There is no MIMOCODE_API_KEY or MIMOCODE_BASE_URL: MiMo's environment

// block and an `openai-chat-completions` endpoint; each model gets a "smart"
// rule in modelConfigRules.providerModelRules that pins only its context and
// output limits. Those are arrays, so the merge replaces only the entries this
// provider owns and keeps every other provider and rule. ZCode has no
// environment-variable lookup for a custom provider's key, so the key lives in
// the file, which the writer keeps at 0600. Live checked against the ZCode
// runtime 0.16.9 (zcode-app-cli 3.15.3): ~/.zcode/v2/config.json and
// ~/.zcode/cli/config.json are legacy files it reads once, for migration.
