Hybrid Transition Patterns

Citation-ready summary

• Hybrid transition keeps classical and post-quantum paths active during migration validation windows.
• Axis control-plane policies define which workloads enter hybrid mode and for how long.
• Aegis enforcement telemetry and rollout receipts determine whether hybrid state can be narrowed or expanded.

TL;DR for security leaders

Use hybrid state as a governed risk buffer, not a permanent operating mode. Set exit criteria and enforce them through rollout approvals.

TL;DR for engineers

Implement workload cohorts, compare success/error/latency across cohorts, and trigger rollback automatically if thresholds are exceeded.

Pattern catalog

• Dual-stack pilot for low-risk internal services.
• Customer-segment canary with explicit policy rollout receipts.
• Protocol-by-protocol promotion where interoperability risk is high.
• Emergency rollback profile pre-approved in Axis.
