- Family reference-profile markers
- ● 2 Standard · ○ 0 Common · △ 1 Variant · 18 unmarked

- 2 released source-BOM records
- Relationship meaning
- Family markers describe reference applicability. Component links are released source-BOM listings and do not assert complete engineering containment.
FAMILY REFERENCE APPLICABILITY
Family profiles carrying a source marker.
Unmarked Families are not listed; an unmarked cell means “not normally fitted” in the source Family profile, not confirmed absence from a vessel.
RELEASED SOURCE-BOM LISTING
Released Component records.
Coverage is partial and Family-independent: selecting a Family does not alter the Component records linked to this System.
