LdeleteAll
deleteAll(options Object optional): Promise
Deletes all stored data, effectively deallocating all storage used by the Durable Object. For Durable Objects with a key-value storage backend, deleteAll() removes all keys and associated values for an individual Durable Object. For Durable Objects with a SQLite storage backend, deleteAll() removes the entire contents of a Durable Object's private SQLite database, including both SQL data and key-value data.

sayHello RCP or the alarm API could be called from a WFP user script?

await this.ctx.storage.setAlarm(Date.now()); ) could I run into any issues? Are there any gotchas here? I have been using this and it works, however, I have encountered (what seems to be) race conditions with this async work so I wonder if that immediate alarm has anything to do with this.JJ

this.state.acceptWebSocket(socket, topic), then to find connections by topic you would do this.state.getWebSockets(topic)DL
this.storage.transactionSync(() => {...}) directly. In the callback, you can do a query, process it with code, do another query, etc. Then, every storage operation in that callback will either all-succeed or all-fail.
