Hermes Agent routing flaw silently switched user to metered OpenRouter, costing $100

A user reports a dangerous provider-routing flaw in Hermes Agent v0.21.0/v0.21.1: running /model gpt-6-astra from an OpenAI Codex thread silently switched routing to metered OpenRouter, because /model checks static catalogs where Astra is missing from Codex's list but present on OpenRouter. Workaround: pin the provider explicitly with --provider openai-codex. Total cost of the lesson: about $100.
