What
The telemetry for the process.spawn event, which records when Claude Code launches a subprocess, now checks that each output chunk it captures has a valid shape: a stream field that is either stdout or stderr, and a text field that is a non-empty string. If a chunk doesn't match, an error label is surfaced instead.
Why
This catches malformed process output data at the telemetry layer, helping ensure spawn-related telemetry stays reliable rather than silently recording broken entries.
