| # Discordant substitution triplets | |
| Status: **complete**. Admitted **20** triplets. | |
| Skipped: {'no_identity': 60, 'no_distractor': 3}. | |
| Each triplet encodes a supplier-attested perceptual preference whose structurally-closest alternative disagrees — the case where Morgan-style structural ranking fails and perceptual representations (POM) should win. | |
