log_exchangeAfter each user message, send the exchange here so it can be remembered. You do not need to decide what is important — just forward the user message (and your reply, if you have one) and Synap will keep what matters. If your app serves more than one end-user, pass that person's stable id as user_id (or an organization id as customer_id) so each person's memory stays separate; if every conversation is the same single user, omit them. Logging is fire-and-forget by default; set wait_for_processing=true only when you need to confirm the memory finished extracting before continuing.
check_memory_statusCheck whether a logged exchange has finished processing. Pass the ingestion_id returned by log_exchange. Returns the processing status and how many memories were extracted. Useful to confirm a save completed (extraction is asynchronous).
recall_contextBefore replying, call this to recall anything already known about this user from past conversations. Use the user's latest message as the query. If you serve multiple end-users, pass the same user_id (or customer_id) you log with so you recall the right person's memory.
list_recent_memoriesList recent things remembered about this user. Useful for debugging or to confirm that memory is working. Pass user_id/customer_id to scope to one person.
