View: Render Subjects using Display Rules

[alistair3149]

Result of planning session with @alistair3149.
Context: the NeoWiki codebase and ADR 018 (Views).
_{Written by Claude Code, Opus 4.6}

Summary

Wire Views into Subject display. When a View is specified, use its Display Rules to:

• Filter properties to only those listed (allowlist behavior)
• Order properties according to the Display Rules order
• Apply display attribute overrides from Display Rules, falling back to Property Definition defaults

When no View is specified, fall back to showing all properties in Schema-defined order (current AutomaticInfobox
behavior). This fallback also applies when a referenced View no longer exists.

When a View has no Display Rules (empty or absent list), all properties are shown in Schema-defined order
(ADR 018).

Dependencies

• View: Split Property Definition attributes into constraints and displayAttributes #658 (Property Definition constraints/displayAttributes split)
• View: View Type plugin system #659 (View Type plugin system)

Scope

• Implement rendering logic that takes a View + Subject and produces display output
• Integrate with the View Type plugin to delegate type-specific rendering
• Apply Display Rule overrides on top of Property Definition displayAttributes
• Ensure the AutomaticInfobox becomes the fallback rendering path
