dsh-llm-fallbacks: Configuring Backup Model Chains for DSH Agents When LLM Fails

dsh-llm-fallbacks is a DSH model inference plugin maintained by omdsh-dev. When an agent's LLM request fails due to retry exhaustion, authentication, quota, or rate limiting, it automatically switches according to the current role's provider/model fallback chain and continues the current step on the target model. It supports 24-hour rootChain, time-based rotation, and sub-agent role rules, with a shared fallbacks configuration for both the web interface and dsh-tui. Installation: dsh plugin --profile web|dsh-tui add dsh-llm-fallbacks. It must be explicitly enabled with enabled: true, and the chain must end with the official V4 Default model.
