What
Stream-json is a machine-readable output format that sends a series of messages, called frames. The internal description of the frame that reports status changes now covers helpers started with --attach-serve. These helpers do not send an init message, so their first frame (sequence number 1) lists every key and acts as the first full snapshot.
Why
A program reading this output from such a helper should treat the first status frame as the complete starting state, because no init message comes before it.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The description is marked internal, and the finding does not say how `--attach-serve` is used or reached.
