👨‍💼 Nice work. Before implementing the newly justified host-login work, you identified the user journeys that matter most and made the non-negotiable experience constraints explicit.

🦉 This is the point of the exercise: strong engineers do not wait for login to ship before deciding what was important. They define the critical flows, invariants, and degradation signals up front so implementation tradeoffs can be judged against something concrete.

In the next step, you'll turn those invariants into an implementation plan that aims to add host login without regressing the product's most important UX.
