What
The internal function that logs completion telemetry now takes and passes along a rawRequestBodyId value (previously stored under a differently named slot), and forwards a requestBodyId into the code path that saves assistant responses.
Why
This is internal bookkeeping for how Claude Code correlates a logged response with the request that produced it. It has no direct effect on how you use the tool.
