- Observational memory search supports group filtering, ordering, and direct record lookup
- Memory recall can page through observation groups around search hits
- Playground UI gains new accessible form field primitives (Field, Fieldset, Form, SearchInput)
Improvements
- Large thread history loading improved from quadratic to linear time complexity
