E.17.1:8 - Common Anti-Patterns and How to Avoid Them

Anti-pattern	What it looks like	How FPF prevents it
Publication-face hijack	A family designator is reused as a publication-face name or document type.	`CC-VBL-5` keeps the ordinary designator distinct from a publication face, form, carrier, viewpoint reference, or exact member.
Bundle equals view collection	A folder or report pack is called a viewpoint bundle even though no exact `U.ViewpointRef` values resolve to admitted `U.Viewpoint` epistemes.	`E.17.1` defines the bundle as a declared family of exact viewpoint references, not a file grouping.
Silent local drift	A local project keeps the old family designator but swaps in different viewpoints.	`CC-VBL-6` requires another catalogue edition carrying the revised or new family declaration when member references, targets, family meaning, or compatibility constraints change.
Namespace collapse	Engineering and publication viewpoint designators are mixed as if they were one lexical namespace.	The solution keeps the designator namespaces distinct and requires explicit attribution.
