-- Agent conversations (#56): multi-turn chat with the garden assistant.
|
|
--
|
|
-- "Now do the same to the north bed" needs the previous exchange, and history
|
|
-- held only by the client would be lost on a refresh — which is exactly when
|
|
-- someone reloads to see whether the agent's change actually landed.
|
|
--
|
|
-- One conversation per (user, garden). Two people editing a shared garden get
|
|
-- separate threads: a conversation is a dialogue with one person, and merging
|
|
-- them would put words in someone's mouth.
