The topics below are platform-level concerns that affect how the builder operates inside the larger multi-tenant shell, but they are not part of the builder's core specification. ## **1. Plugin / Module Lifecycle** These topics belong to the broader platform architecture, not the builder PRD: * Module installation * Activation and deactivation * Uninstall behavior * Upgrade and migration rules * Dependency handling * Missing extension-point handling * Failure recovery when a module is removed or replaced * Long-term compatibility management ## **2. Screen Ownership and Editable Zones** These topics define what parts of the shell can be edited by which classes of users: * Shell-owned areas versus module-owned areas * Super User full-screen edit powers * Agency Admin edit limits * Future developer-specific edit rules * Locked regions, protected regions, and extension-point regions ## **3. Scope of Change** These topics define where edits apply once published: * Global shell-wide changes * Module-wide default changes * Agency-level changes * Agency-client inherited changes * Tenant-specific overrides * Page-instance-specific overrides * Environment-specific differences ## **4. Inheritance and Override Model** These topics define how changes trickle down through the platform: * Global defaults * Module defaults * Agency-level overrides * Tenant or client-type overrides * Page-level overrides * Resolution order when multiple override layers exist ## **5. Collaboration and Concurrency** These topics govern how multiple people interact with the same artifacts: * Single-editor versus multi-editor model * Record locking * Live presence indicators * Conflict handling * Review or approval workflows * Comments and internal collaboration features ## **6. Event Model and Platform Observability** These topics belong to the shell and platform telemetry layer: * Runtime module events * Builder action events for auditing * Publish events * Rollback events * Monitoring and tracing across modules * Event bus governance and observability standards ## **7. Security and Governance at the Platform Level** These topics affect the entire shell and should be specified globally: * Sensitive capability access rules * Secret handling policy * Permission inheritance rules * Restricted modules or non-editable system surfaces * AI prompt exposure and data masking policies * Approval thresholds for high-risk changes ## **8. Exportability, Portability, and Reuse Across Environments** These topics apply to the platform's broader module strategy: * Packaging modules for reuse outside the platform * Duplicating modules across environments * Copying layouts across agencies or tenants * Template packaging and distribution * Version portability and deployment targets ## **9. Navigation and Information Architecture Registration** These topics belong to the shell and routing system: * How new pages register in navigation * Sidebar label control * Route generation * Hidden pages and internal pages * Icon assignment * Cleanup behavior when pages are deleted or disabled ## **10. Naming and Object Vocabulary Across the Platform** These topics should be resolved in the broader platform PRD so terminology remains consistent: * Module vs plugin vs app * Page vs screen vs surface * Capability vs function vs service * Data source vs binding vs contract * Draft vs version vs published release * Extension point vs slot vs mount point ## **11. Recovery and Failure UX Outside the Builder Core** These topics concern platform-wide resilience: * What happens when a module is removed * What happens when a dependency is missing * How the shell handles broken bindings after upgrades * How users are notified about missing capabilities * Recovery options across the broader system ## **12. Long-Term Platform Policy for External Component Ecosystems** The Layout Manager PRD will assume shadcn/ui is the UI foundation and that broader shadcn-compatible components may be used. The broader platform PRD should later define: * How external component sources are approved * How component updates are governed across the platform * Versioning and compatibility policy for imported component packs * Trust and review workflow for third-party additions ## **Notes for the Layout Manager PRD** The following items remain in scope for the Layout Manager PRD and should not be moved here: * Source of truth for layouts and functionality bindings * Builder edit history, undo/redo, draft, preview, publish, rollback behavior * AI permissions and AI workflow stages inside the builder * Component registration rules needed specifically for builder compatibility * Data-source binding UX and AI-guided capability creation inside the component properties flow * Validation gates required before builder publish * Builder testing flow * Builder performance expectations This document exists only to keep the Layout Manager PRD focused while preserving the unresolved platform-level concerns for the future platform PRD.
