As USER, in Connectors, i press OpenRouter
As USER i give my OpenRouter API key, and the namespace i am standing in keeps it sealed (ADR-051)
As USER i am never shown the key again
"but only one is ever active for the namespace agent"
As USER the key i set last is the one the namespace agent uses
As USER, in Connectors, i press Anthropic or OpenAI, and give that key the same way: the namespace agent in Pi calls each provider with its own key (ADR-053)
