+# Pattern: Break-Glass Access
+
+Status: reviewed
+Readiness target: RL3 production
+Primary owners: NetKingdom, Railiance platform
+
+## Problem
+
+Operators need a recovery path when normal identity, policy, cluster, or
+secret services fail, but emergency access can easily become an
+unbounded platform-root bypass.
+
+## Context
+
+Use this pattern for OpenBao recovery, cluster recovery, privileged
+account recovery, incident containment, and platform restore workflows.
+
+## Forces
+
+- Emergency access must work during partial outages.
+- It must be limited, auditable, and rarely used.
+- Tenant administrators must not receive platform-root powers.
+- Post-event review must turn emergency use into durable fixes.
+
+## Solution
+
+Define a small emergency path with explicit custody, MFA or quorum where
+possible, narrow scope, recorded use, and mandatory post-event review.
+Keep it separate from ordinary administration.
+
+## Implementation Sketch
+
+1. Identify emergency scenarios and required minimum authority.
+2. Store emergency material separately with named custodians.
+3. Require ceremony, reason, and timestamp for use.
+4. Alert on activation where systems are available.
+5. Rotate or reseal affected credentials after use.
+6. Run post-event review and close follow-up tasks.
+
+## Failure Modes
+
+| Failure | Mitigation |
+| --- | --- |
+| Break-glass becomes routine admin | require review and track frequency |
+| Emergency access is too broad | define scenario-specific bundles |
+| Recovery material is stale | run drills and rotation checks |
+| Tenant admins gain platform-root access | hard-separate tenant and platform authority |
+
+## Related Capabilities
+
+- Incident response and recovery.
+- Privileged access management.
+- Secrets, keys, and credentials.
+- Security governance and production readiness.
+
+## Maturity
+
+Reviewed. The concept is anchored in NetKingdom/OpenBao planning, but
+drills and custody evidence are required before canonical graduation.
+
+## Verification
+
+- Emergency path is documented and tested.
+- Activation produces an event record and follow-up review.
+- Credentials are rotated or revalidated after use.
+- Tenant and platform emergency powers are separated.
+
+## Research Basis
+
+Seeded by break-glass access, incident response process, backup restore,
+and secret-zero avoidance requirements.
