LM Studio users see leaked Gemma tokens

Likely a template or formatting mismatch rather than random model noise, so the cleaner fix is at the server/config layer rather than in a proxy.

• –LM Studio supports automatic prompt templates, manual overrides, and per-model prompt template customization, so a bad or incomplete template is a plausible cause.
• –LM Studio also supports structured outputs via JSON schema on its OpenAI-compatible server, which is a more principled route when the model is supposed to emit JSON.
• –The thread reflects a real failure mode for local serving: models can expose internal control markers when the serving stack and model formatting expectations are out of sync.
• –The proxy workaround is practical, but it is a band-aid if the root cause is the prompt template or output mode.
