* use observation in unit and preview tests instead of the async stream * use a parsing approach that is independent of the sourcery annotation * Fix observation deferred fulfillments not receiving the initial value Observation's observe only emits transitions, not the value present at subscription time. Drop the leading initial value from the affected transitionValues sequences and assert it directly with #expect instead. * improved docs
