+### Check removed mappings and invalid evidence
+The pipeline removes mappings that would violate the current JSON schema, and outputs them to `${BATCH_ROOT}/logs/removed_mappings.tsv`.
+Check that this file is empty, or only contains expected mappings (e.g. within the material entity branch of EFO).
+This can be confirmed with the Open Targets data team if needed.

+Any invalid evidence strings are dropped and output in `${BATCH_ROOT}/evidence/invalid_evidence.json`.
+Check that this file is empty, or only contains expected evidence given the current state of development (e.g. 
+unsupported clinical significance terms or other unsupported features).
+Anything unusual should be raised with the Open Targets team so it can be addressed as a priority.
