This record contains a non-binding bundle index for the ΠΡΟΣΗΜΑ–ΠΡΟΘΥΜΙΑ pre-contact friction stack. The document exists solely as a preservation and navigation reference listing independent, sealed artifacts and their canonical records. The index introduces no new mechanisms, requirements, or claims. It does not enforce behavior, assert authority, or imply governance. It does not claim safety, alignment, compliance, or prevention and does not monitor, restrict, or intervene in any system or actor. The bundle index lists: ΠΡΟΣΗΜΑ — a first-contact friction placard encountered before interpretation ΠΡΟΘΥΜΙΑ — a universal pre-engagement friction stack encountered before engagement or action ΠΡΟΣΗΜΑ ↔ ΠΡΟΘΥΜΙΑ — a descriptive timing and placement map clarifying their relationship All artifacts remain independent. None contains, governs, or depends on another. Their relationship is sequential, not hierarchical.
