RECOVERY ENGINEERING · DOWNUM CYBER

Recovery without blindly replaying uncertain effects

Ruby’s recovery direction preserves nonterminal state so interrupted work can be reconciled, resumed, rolled back, or stopped safely.

WHAT CHANGED

DATE PENDING EVIDENCE

STATUS — DRAFT SOURCE MATERIAL

## ENGINEERING PROBLEM

A crash can leave an operation between maybe happened and unknown outcome.

## CURRENT DIRECTION

The draft direction uses durable intent, effect evidence, independent verification, and fail-closed unknown-outcome handling.

## LESSON

Backup exists does not mean recovery works.

## CLAIM BOUNDARY

This entry is based on owner-reviewed Ruby draft material, not the deeper evidence-manifest package. It does not claim AGI, consciousness, unrestricted autonomy, or a production-certified capability.

Boundary

This entry describes public-safe engineering context only. It does not publish production topology, addresses, credentials, procedures, telemetry, or exploitable configuration.
