ah, i saw this same kooky error in my colleague's VScode GUI, and it's complete nonsense, because if you go to the nostr/envelopes directory, you find this:
https://mleku.net/nostr/blob/master/envelopes/sentinel/read.go
package sentinel
...
func Read(buf *text.Buffer, match string) (env enveloper.I, err error) {
idk what the fuck this is coming up from, but it's wrong
we had this same shit appear in the VScode IDE when it was on the github repo too, i'm very curious to know why it flags this error because it's nonsensical
