C.2.2:12 - Relations

Builds on: C.2 (KD-CAL overview), A.2.6 (claim scope and scope revision), C.2.3 (Formality F), B.3 and B.3.3/B.3.4 (assurance, evidence lanes, and refresh), B.1.3 (Γ-fold patterns), C.3.3 (cross-kind use), G.6 (EvidenceGraph PathId discipline), C.29/A.6.3.RT (notation and representation relations), A.1.1 (selected model-use structure), and A.10/B.3 for exact evidence-use and reliance relations. F.9 is used only when an obtaining relation between distinct local meanings, reference schemes, or reference planes is part of the path. Coordinates with: C.16 for measurement claims, E.14 for working-model assertions, F.17 for optional local-meaning addresses, and E.18/E.17/A.21 when their own transfer, publication, or gate objects are current. G.2 supplies relevant source-pack entries; G.7 remains the conditional calibration path for its declared cross-Tradition/F.9 Bridge use, not a universal calibration owner. Used by: C.3.3 for cross-kind reuse discipline, guard macro bundles in C.3.A and C.21, and acceptance or gating logic that consumes R_eff while preserving F and G. Clarifies: the KD-CAL meaning of reliability implicit in C.2:4.1 and the relation-specific reuse claims referenced across B.3 and C.3; it does not create a universal transport relation.
