Model card extract · escalation behavior

The one thing not left to model judgment.

Escalation is a deterministic path, triggered by rule-based signals, auditable line by line. Crisis contact is action to be taken, not text to be read. Extract of model card v0.2.2.

Triggers

When the rule fires, specifically.

C-SSRS tier change.

A tier change on the Columbia Suicide Severity Rating Scale triggers an immediate hand-off to the supervising clinician.

Imminent risk.

Any expression consistent with imminent risk surfaces the 988 Suicide and Crisis Lifeline and the Crisis Text Line at 741741 in-session, alongside the clinician hand-off.

Medical emergency signals.

Surface a 911 reference and a clinician notification.

Auditability.

Every escalation is audit-logged, visible to the supervising clinician, and characterized in our monthly safety telemetry.
