RECOVERY ENGINEERING · RAGNAROK

Recoverability as a release requirement

A migration failure-path defect was found, corrected, and reverified through structural, isolated application, and rollback checks.

WHAT CHANGED

STATUS — PRODUCTION ACCEPTED

## CONTEXT

The migration failure path exposed a restoration ownership and mode issue.

## ENGINEERING CHANGE

Coherent state was restored, the issue corrected, and structural, isolated application, and rollback checks passed.

## VERIFICATION BOUNDARY

Evidence reference: E01. This is a sanitized first-party account; owner-only records are not imported.

## LESSON

An archive alone is not an operational recovery proof.

Media: no private screenshots. Current RAGNAROK dashboard remains pending owner delivery.
