A failure carries only the fields its `client` and `internal` blocks declare.  next: Remove `search`, or declare it in `Missing`'s `client` or `internal` block (agent)  rule: failure.unknown_context_field  help: https://jadpo.dev/docs/errors/failure.unknown_context_fieldcheck failed: 1 error, 1 file
