description: >-
  Client-side error registry of the BidMachine Plus SDK (BidMachineError.code), published verbatim at
  mediation-docs.bidmachine.io for Android, iOS and Unity (the three pages carry the same table). These
  are SDK/runtime errors surfaced to the app in load/show callbacks, not HTTP API errors — the REST
  API surface is in errors/bidmachine-io-problem-types.yml. The provider's own agent skills ship the
  same table as skills/bidmachine-*/references/error-codes.md.
log_format:
  single: '(<code>) <message>'
  chained: '(<code>) <message> - (<causeCode>) <causeMessage>'
