What

Errors from the SDK's subprocess transport are wrapped with a redacted telemetryMessage and an errorClass so failures can be grouped.

Details
  • classes include spawn_failed, process_exited_nonzero, process_killed_by_signal, executable_not_found and control_request_failed
  • covers spawn failures, non-zero exits, signal kills, aborts, control-request failures and error results
  • stderr tails and filesystem paths are redacted before being attached
Evidence

process_killed_by_signal

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
