Snowflake Failover Readiness Drill

Purpose

Produces a deterministic readiness or attestation result from exact, independently trusted evidence. It observes and verifies but never performs or authorizes a Snowflake control-plane change.

Prerequisites

• Python 3.10+ and this complete skill directory, including its reviewed SQL.
• An owner-approved scope and separately retained digests for policy, collection, and operator/validation evidence.
• Existing least-privilege Snowflake CLI profiles in source and target accounts when live collection is required. Profiles used for Information Schema history, progress, or dangling functions must select an approved current database; the skill does not configure authentication or session state.
• Business Critical Edition or higher for failover groups.
