Record identity and ownership

Persist records by stable identity, not UI position. For a weapon/profile editor, the record should be keyed by a stable weapon/profile ID. Primary/secondary/menu positions are views of that identity, not storage owners.

Store with each record:

• magic or valid/copied marker;

• schema version;

• stable identity;

• logical length;

• field values;

• optional checksum or metadata if supported by the design.

Keep immutable factory data separate from editable persistent records so reset/copy operations have a trustworthy source.
