Companion

Headers whose values never leave the process, replaced with * before the event is built. Pass your own set to BodyCapture to add to it; these are the ones that are always wrong to record.

Open-ended streams. Reading one waits for traffic that may never come.

Content-type prefixes read as text. A body whose type is not one of these is skipped rather than captured as bytes: an image or a protobuf is noise in a timeline, and large.

No bodies at all. Phases, timings, status codes and headers still flow.

Both directions, text content types, 4KB each.
