DisMech.

A disorder mechanisms knowledge base, not a clinical guideline and not a patient record.

DisMech (Disorder Mechanisms Knowledge Base) is built by the Monarch Initiative. It holds human pathophysiology as structured pathographs: mechanisms, HPO phenotypes, genetics, MAXO treatment annotations, and literature evidence with exact-quote snippets, validated under a LinkML schema. It mints no new ontology terms. It exports under infores:dismech.

Sniff does not re-host that knowledge base. We do not paraphrase its quotes. We do not turn MAXO annotations into advice for a dog.

The mechanism depth behind the human analog, when Mondo already names the bridge.

When a canine disease page has a Mondo model-of link, and DisMech has a page for that same Mondo id, Sniff deep-links to the mechanism page. The dog disease remains the subject. The human mechanism is about people. The relation is always model-of, never identity.

Join coverage is honest: as of 2026-07-21, 27 of our Mondo-bridged canine disease pages have a verified live DisMech URL. Many OMIA bridges point at subtype Mondo ids that DisMech has not yet page-published at that grain. We omit those rather than invent a parent-term join.

Complementary offer the other direction: Sniff can later contribute spontaneous canine / veterinary-series evidence into DisMech as MODEL_ORGANISM items, with verbatim abstract snippets only and human review. That is not live yet. The verbatim bar is load-bearing (their validator rejects paraphrase).

• Not treatment advice for a dog (MAXO stays human-register).
• Not a claim that dog disease equals human disease.
• Not federation of mechanism narrative into the Sniff KGX bundle (facts-only; INV-54 / INV-67).
• Not an auto-PR into monarch-initiative/dismech.
