v2026.9.4

Fixed

• OpenCode Free stopped answering once an API key was entered. The gateway admits the free tier only on the credential the product supplies, so a key typed into the OpenCode Free card replaced it and every free model returned 401 Invalid API key. Switching models did not help — the free routes share one credential — and there was no way to clear the key from the app. The credential now arrives from the launch environment, which outranks the stored one: the key field on that card is read-only, and an install that already holds a typed key starts answering again on upgrade with nothing to clean up. (#1641)

Under the hood

• Refreshed the OpenCode Zen client identity to the current desktop release, so the app keeps the free-tier quota pool it is entitled to. (#1640)
• The desktop smoke test now sends a real free-model turn, so a broken free route fails CI instead of shipping. (#1637)

修复

• 填过 API Key 之后 OpenCode Free 全部失效。 网关只认产品自己提供的那个凭据才放行免费额度，所以在 OpenCode Free 卡片里填的 Key 会把它顶掉，六个免费模型全部返回 401 API 密钥无效。换模型没用——这些免费路由共用同一个凭据——而且应用里没有任何地方能把填进去的 Key 清掉。现在这个凭据改由启动环境提供，优先级高于存储层：该卡片的密钥输入框变为只读；已经填过 Key 的安装升级后会自动恢复，不需要手动清理任何东西。(#1641)

内部改动

• 将 OpenCode Zen 的客户端身份刷新到当前桌面版本，保证应用继续使用它应得的免费额度池。(#1640)
• 桌面冒烟测试现在会真实发起一轮免费模型对话，免费路由坏掉会在 CI 阶段失败，而不是发出去之后才发现。(#1637)
