Syndrome Incidence Dashboard — Model v3.2 (Last 30 Days)
200 evaluated traces — June 2026
3 ALERTS
⚠ Overall incidence: 44% — 88 of 200 traces flagged with at least one syndrome. Aggregate rate exceeds the 40% watch threshold.

⚠ Plausible Helpfulness has crossed the per-syndrome alert threshold at 12% incidence (24 traces). Action required. Click the PH bar for the full engineering drill-down.

⚠ Responsibility Diffusion is approaching its threshold at 9% incidence (18 traces). Prepare a remediation plan. Click the RD bar to review micro-failure tag detail.

How to read this dashboard

Each bar represents one Core Six syndrome’s incidence rate across the evaluated trace sample. The red bar has crossed the alert threshold — it’s the primary finding for this period. Amber means approaching threshold and worth watching; blue bars are within acceptable range.

Layer 1 → Layer 2: Click any syndrome row to open the engineering drill-down for that syndrome. Layer 2 breaks the incidence down into specific micro-failure tags, surfaces common behavioral patterns, and surfaces suggested remediation targets you can take directly to a model developer or vendor.

📝
Vendor management implication: If you’re already running periodic model reviews or quarterly vendor check-ins, this dashboard maps directly onto that workflow. Layer 1 gives you the headline — the one number to put in a briefing. Layer 2 gives you the evidence packet: the specific failure tags and remediation items to put on the table in a vendor conversation, a contract SLA review, or a re-evaluation decision. You don’t need to build new processes — this fits inside the ones you likely already have.
