[user_blocked] Muse Spark 1.3 Free access restricted via OpenCode Zen — no appeal path

Description

While using OpenCode with the Muse Spark 1.3 Free model through the OpenCode Zen provider, every message returns the following error, in both new and existing sessions:

Error: Error from provider (Console): Upstream request failed: [user_blocked] Your access has been restricted due to repeated policy violations.

I was not doing anything unusual — just normal prompting for a project I'm currently working on. The block persists across brand-new sessions with no context carried over, and there is no visible way to see what specific "policy violation" triggered it or how to appeal it from within the app.

Plugins

None / default installation (no custom plugins)

OpenCode version

v2.0.3

Steps to reproduce

1. Open OpenCode on Windows
2. Start a new session with the "Build" or "Operator" agent
3. Select provider: OpenCode Zen, model: Muse Spark 1.3 Free
4. Send any prompt (e.g. "HI")
5. The [user_blocked] error returns immediately

Reproduce the reported steps on Windows using OpenCode Zen and the Muse Spark 1.3 Free model, then determine whether the [user_blocked] response is generated by OpenCode or the provider. The issue names no source file, test, or project-owned expected change; progress requires an agreed handling or appeal-path scope before implementation can be considered done.
