Method ResolveAlias

core/config/model_config_loader.go:301–313

ResolveAlias follows a one-hop alias to its target config. Returns (resolved, wasAlias, err). Non-alias configs return (cfg, false, nil) unchanged. Strict: the target must exist and must not itself be an alias (chains are rejected). The returned config is a copy of the target.

(cfg *ModelConfig)

// unchanged. Strict: the target must exist and must not itself be an alias
// (chains are rejected). The returned config is a copy of the target.
func (bcl *ModelConfigLoader) ResolveAlias(cfg *ModelConfig) (*ModelConfig, bool, error) {
	if cfg == nil || !cfg.IsAlias() {
		return cfg, false, nil
	}
	target, exists := bcl.GetModelConfig(cfg.Alias)
	if !exists {
		return nil, true, fmt.Errorf("alias %q points to unknown model %q", cfg.Name, cfg.Alias)
	}
	if target.IsAlias() {
		return nil, true, fmt.Errorf("alias %q points to another alias %q (chains are not allowed)", cfg.Name, cfg.Alias)
	}
	return &target, true, nil
}

// ValidateAliasTarget checks an alias config's target at create/swap time:
// the target must exist, must not be an alias, and must not be disabled.
