Vendor OpenClaw source as Adolf fork baseline

Adolf is a fork/vendored clone of github.com/openclaw/openclaw (v2026.6.11),
free to diverge. Tree copied sans upstream .git; upstream remote added for
future syncs. Node pinned to 24 (.nvmrc); engines already require >=22.19.
Preserves docs/ARCHITECTURE.md.

+summary: "Use OpenCode Zen and Go catalogs with OpenClaw"
+read_when:
+  - You want OpenCode-hosted model access
+  - You want to pick between the Zen and Go catalogs
+title: "OpenCode"
+---
+
+OpenCode exposes two hosted catalogs in OpenClaw:
+
+| Catalog | Prefix            | Runtime provider |
+| ------- | ----------------- | ---------------- |
+| **Zen** | `opencode/...`    | `opencode`       |
+| **Go**  | `opencode-go/...` | `opencode-go`    |
+
+Both catalogs share one OpenCode API key (`OPENCODE_API_KEY`, alias
+`OPENCODE_ZEN_API_KEY`). OpenClaw keeps the runtime provider ids split so
+upstream per-model routing stays correct, but onboarding and docs treat them as
+one OpenCode setup.
+
+## Getting started
+
+<Tabs>
+  <Tab title="Zen catalog">
+    **Best for:** the curated OpenCode multi-model proxy (Claude, GPT, Gemini, GLM,
+    DeepSeek, Kimi, MiniMax, Qwen).
+
+    <Steps>
+      <Step title="Run onboarding">
+        ```bash
+        openclaw onboard --auth-choice opencode-zen
+        ```
+
+        Or pass the key directly:
+
+        ```bash
+        openclaw onboard --opencode-zen-api-key "$OPENCODE_API_KEY"
+        ```
+      </Step>
+      <Step title="Set a Zen model as the default">
+        ```bash
+        openclaw config set agents.defaults.model.primary "opencode/claude-opus-4-6"
+        ```
+      </Step>
+      <Step title="Verify models are available">
+        ```bash
+        openclaw models list --provider opencode
+        ```
+      </Step>
+    </Steps>
+
+  </Tab>
+
+  <Tab title="Go catalog">
+    **Best for:** the OpenCode-hosted Kimi, GLM, MiniMax, Qwen, and DeepSeek lineup.
+
+    <Steps>
+      <Step title="Run onboarding">
+        ```bash
+        openclaw onboard --auth-choice opencode-go
+        ```
+
+        Or pass the key directly:
+
+        ```bash
+        openclaw onboard --opencode-go-api-key "$OPENCODE_API_KEY"
+        ```
+      </Step>
+      <Step title="Set a Go model as the default">
+        ```bash
+        openclaw config set agents.defaults.model.primary "opencode-go/kimi-k2.6"
+        ```
+      </Step>
+      <Step title="Verify models are available">
+        ```bash
+        openclaw models list --provider opencode-go
+        ```
+      </Step>
+    </Steps>
+
+  </Tab>

+
+## Config example
+
+```json5
+{
+  env: { OPENCODE_API_KEY: "sk-..." },
+  agents: { defaults: { model: { primary: "opencode/claude-opus-4-6" } } },
+}
+```
+
+## Built-in catalogs
+
+### Zen
+
+| Property         | Value                                                                                         |
+| ---------------- | --------------------------------------------------------------------------------------------- |
+| Runtime provider | `opencode`                                                                                    |
+| Example models   | `opencode/claude-opus-4-6`, `opencode/gpt-5.5`, `opencode/gemini-3.1-pro`, `opencode/glm-5.2` |
+
+Run `openclaw models list --provider opencode` for the full current list, which
+also includes free-tier rows such as `opencode/big-pickle` and
+`opencode/deepseek-v4-flash-free`.
+
+### Go
+
+| Property         | Value                                                                    |
+| ---------------- | ------------------------------------------------------------------------ |
+| Runtime provider | `opencode-go`                                                            |
+| Example models   | `opencode-go/kimi-k2.6`, `opencode-go/glm-5`, `opencode-go/minimax-m2.5` |
+
+See [OpenCode Go](/providers/opencode-go) for the full Go model table.

+## Advanced configuration
+
+<AccordionGroup>
+  <Accordion title="API key aliases">
+    `OPENCODE_ZEN_API_KEY` is also accepted as an alias for `OPENCODE_API_KEY`.
+  </Accordion>
+
+  <Accordion title="Shared credentials">
+    Entering one OpenCode key during setup stores credentials for both runtime
+    providers. You do not need to onboard each catalog separately.
+  </Accordion>
+
+  <Accordion title="Getting an API key">
+    Create an OpenCode account and generate an API key at
+    [opencode.ai/auth](https://opencode.ai/auth). Billing and catalog
+    availability are managed from the OpenCode dashboard.
+  </Accordion>
+
+  <Accordion title="Gemini replay behavior">
+    Gemini-backed OpenCode refs stay on the proxy-Gemini path, so OpenClaw keeps
+    Gemini thought-signature sanitation there without enabling native Gemini
+    replay validation or bootstrap rewrites.
+  </Accordion>
+
+  <Accordion title="Non-Gemini replay behavior">
+    Non-Gemini OpenCode refs keep the minimal OpenAI-compatible replay policy.
+  </Accordion>
+</AccordionGroup>
