| ImagesScanned | Eligible indirect image streams examined |
|---|---|
| ImagesDecoded | Images decoded successfully into the comparison sample |
| DecodeFailures | Images excluded because decoding failed |
| CanonicalImages | Distinct images retained after accepted matches are grouped |
| HashCandidates | Indexed band candidates considered before semantic and distance rejection |
| CandidateComparisons | Candidate pairs that reached decoded sample comparison |
| ImagesDeduplicated | Images accepted as perceptual duplicates |
| ReferencesRepointed | References redirected during a live run or reportable during a dry run |
| OrphanObjectsRemoved | Objects removed by optional garbage collection |
| MaxAcceptedHashDistance | Largest difference-hash Hamming distance among accepted pairs |
| MaxAcceptedChannelError | Largest individual channel error among accepted pairs |
| SamplesCompared | Colour-channel values examined by sample confirmation |
| DuplicatePayloadBytes | Encoded payload bytes represented by accepted duplicate image streams |
| MaxAcceptedMeanError | Largest mean absolute channel error among accepted pairs |
