Model configuration
Database-driven models, providers, and per-agent overrides.
Registry
Models are not hardcoded. Deploy stores model_configs with provider, capabilities, pricing metadata, and default generation parameters.
Per agent
Each agent references a model_config_id and may supply overrides (temperature, max tokens, etc.).
Plugins
New providers ship as model plugins in the monorepo; configuration rows + plugins unlock additional models without redeploying business logic.
See SPEC.md §7 for the ModelAdapter interface.
