+Defaults to `report` in Composer 2.6, and defaults to `fail` from Composer 2.7 on. Defines whether the audit command reports abandoned packages or not, this has three possible values:
+
+- `ignore` means the audit command does not consider abandoned packages at all.
+- `report` means abandoned packages are reported as an error but do not cause the command to exit with a non-zero code.
+- `fail` means abandoned packages will cause audits to fail with a non-zero code.
