Security References

Trinity’s source material defines information control and physical access as separate authorities. The archive preserves that distinction.

Controlling references

• TL-SEC-04 — Information Security Classification System
• TL-SEC-001 — Security Access Classification System

Derived reference

• TL-SEC-001 Reference — Endorsements & Facility Conditions

Interpretation rule

An information level such as TL-4 is not a facility badge. A physical level such as S-4 / C-R-X is not permission to read compartmented records.

• Clearance establishes eligibility.
• Compartment authorization establishes access.
• Need-to-know establishes permission.
• Physical security authority governs location and interaction.
