<Warning>
  **`server.integrations.slack.default_channel` is now literal text.** Replace any `{{ env.NAME }}` token with an explicit channel name. Per-run Slack notification and interview channels still support interpolation.

## GPT-5.6 models

Fabro now includes GPT-5.6 Sol, Terra, and Luna in the built-in OpenAI catalog, routed through the Responses API with a Codex-safe 272K context policy. GPT-5.6 Sol becomes the OpenAI default, while all three models expose their current capabilities, reasoning controls, limits, aliases, and pricing.
