=== ADMIN PANEL UI ARCHITECTURE === Product: NexusFlow B2B Platform Product Type: Multi-tenant SaaS workflow automation platform Primary Operators: Platform administrators, support agents, billing administrators, security reviewers, organization administrators, and read-only auditors. === EXECUTIVE SUMMARY === NexusFlow requires an operations-focused administration system that keeps tenant, workspace, environment, authorization, and action risk visible throughout the interface. The recommended architecture should be organized around operator domains rather than backend services: 1. Overview 2. Organizations 3. Users 4. Workflows 5. Billing 6. Support 7. Audit Logs 8. Reports 9. Settings The system should include persistent organization context, global entity search, role-aware navigation, structured detail pages, reusable table and filter foundations, safe bulk actions, human-readable audit history, and strong safeguards for impersonation and destructive operations. === OPERATOR PERSONAS === Operator: Platform Administrator Responsibilities: Manage platform-wide organizations, users, roles, integrations, and high-risk system settings. Risk: Critical Data Access: Platform-wide, subject to verified authorization. Operator: Support Agent Responsibilities: Investigate customer problems, review account context, inspect workflow failures, and guide recovery. Risk: High Restrictions: No billing changes, permission changes, refunds, or destructive actions unless explicitly granted. Operator: Billing Administrator Responsibilities: Review subscriptions, invoices, payments, credits, usage, approved refunds, and billing failures. Risk: High Operator: Read-Only Auditor Responsibilities: Review approved reports, audit events, account history, and selected security records. Risk: Medium Restriction: No modifying actions. === SCOPE MODEL === Scopes: - Platform - Organization - Workspace - Project Persistent Scope Indicator: Display the active organization and workspace in the application shell. Environment Indicator: Show Production, Test, or other verified environment clearly. High-Risk Rule: Destructive and billing actions must repeat the active scope inside the confirmation. Cross-Tenant Rule: Search results, lists, exports, and actions must respect server-side tenant authorization. === PRIMARY NAVIGATION === Overview: Operational status and priority queues Organizations: Organization management, ownership, workspaces, plans, usage, and account status Users: Users, invitations, roles, sessions, status, and membership Workflows: Workflow definitions, runs, failures, and integrations Billing: Subscriptions, invoices, payments, credits, refunds, and usage Support: Customer context, tickets, notes, recent failures, and controlled impersonation Audit Logs: Human-readable administrative and security events Reports: Approved operational and billing reports Settings: Platform, organization, security, integration, notification, and developer settings === GLOBAL SEARCH === Searchable Objects: - Users - Organizations - Workspaces - Subscriptions - Invoices - Workflow Runs - Support Tickets Search Result Anatomy: - Entity type - Primary label - Secondary identifier - Organization context - Status - Match reason - Authorized action Rules: - Support exact identifiers. - Mask sensitive fields. - Display tenant context. - Prevent cross-tenant disclosure. - Support keyboard navigation. - Provide no-results and permission-restricted states. === OVERVIEW DASHBOARD === Priority Modules: - Failed workflow runs - Suspended organizations - Payment failures - Pending support escalations - High-risk permission changes - Recent administrative actions - Usage anomalies Each module should answer: - What requires attention? - Why? - Which entity is affected? - What action is available? - Which permission is required? Avoid decorative metrics without operational value. === USER LIST === Primary Columns: - User - Email - Status - Organization - Role - Last Active - Authentication Method - Actions Default Filters: - Status - Organization - Role - Invitation State - Last Active Saved Views: - Pending Invitations - Suspended Users - Recently Active - Locked Accounts - Users Without Verified Membership Row Actions: - View Details - Change Role - Revoke Sessions - Suspend - Restore - Archive High-risk actions should not appear as the first row action. === USER DETAIL PAGE === Header: - Name - Masked identifier - Status - Primary organization - Current role - Primary approved action Sections: - Overview - Organizations and Workspaces - Roles and Permissions - Authentication and Sessions - Workflow Activity - Support History - Audit History Sensitive Fields: Mask or restrict according to verified permissions. === USER STATES === Invited: Invitation sent but not accepted. Pending Verification: Identity or email verification incomplete. Active: Normal account access. Suspended: Access intentionally paused. Locked: Access blocked because of a verified security or policy event. Disabled: Account access disabled by verified operational policy. Archived: Inactive record retained according to verified policy. Deleted: Deletion state and retention behavior require verification. Every state must define: - Meaning - Allowed actions - Restrictions - Recovery - Audit event - Customer notification where required === ORGANIZATION LIST === Columns: - Organization - Owner - Status - Plan - Seats - Usage - Workspaces - Created - Actions Filters: - Status - Plan - Region - Usage level - Payment state - Owner === ORGANIZATION DETAIL === Sections: - Summary - Members - Workspaces - Subscription - Usage - Billing - Integrations - Domains - Security - Support - Activity - Audit Logs High-Risk Actions: - Transfer Ownership - Suspend Organization - Cancel Subscription - Archive Organization - Delete Organization === ROLES AND PERMISSIONS === Authorization Model: Use the verified backend model. Do not infer missing grants.

Select users. 2. Choose Assign Role. 3. Validate eligibility. 4. Identify excluded users. 5. Preview affected users and scope. 6. Confirm. 7. Process asynchronously where required. 8. Show completed, excluded, and failed records. 9. Allow retry for failed records where safe. 10. Record an audit event for every completed change. Do not report complete success when some records fail. === AUDIT LOG === Columns: - Timestamp - Actor - Action - Object - Scope - Result - Source - Details Human-Readable Event: Maya Chen changed Jordan Lee's workspace role from Viewer to Editor. Audit Detail: - Actor - Action - Object - Scope - Timestamp - Result - Source - Before - After - Request or trace identifier - Related events Sensitive values and secrets must be masked. === BILLING ADMINISTRATION === Modules: - Subscriptions - Invoices - Payments - Credits - Usage - Refunds - Payment Failures - Billing Contacts Subscription Detail: - Organization - Plan - Status - Billing period - Renewal - Seats - Usage - Credits - Invoices - Discounts - Cancellation - History Every billing action must show: - Authorization - Effective date - Financial impact - Customer impact - Reason - Confirmation - Audit event - Notification behavior - Recovery when supported === REFUND FLOW === Required Information: - Invoice or payment - Eligible amount - Full or partial refund - Reason - Payment method - Tax behavior - Customer notification - Audit event All eligibility and financial behavior require verification. === LOG VIEWER === Supported Logs: - Workflow Runs - API Requests - Webhooks - Authentication - Integrations - Jobs - Billing Events Columns: - Timestamp - Severity - Source - Message - Status - Duration - Request ID - Related Entity Capabilities: - Search - Filters - Time Range - Structured View - Raw View - Line Wrapping - Copy - Authorized Export - Secret Masking - Retention Explanation === SUPPORT CONSOLE === Sections: - Customer Identity - Organization - Subscription - Usage - Recent Workflow Failures - Support Tickets - Internal Notes - Roles and Permissions - Integrations - Audit History - Impersonation Internal Note Requirements: - Author - Timestamp - Visibility - Category - Edit History - Retention - Sensitivity === IMPERSONATION FLOW === Requirements: - Explicit permission - Required reason - Approved duration - Visible impersonation banner - Clear Exit Impersonation action - Restricted sensitive actions - Audit event - Customer scope - Approval where required - Notification behavior where required Banner Example: You are viewing NexusFlow as Jordan Lee in Acme Operations. Do not allow silent impersonation. === DESTRUCTIVE-ACTION FRAMEWORK === Example: Suspend Organization Confirmation Displays: - Organization name - Active scope - Affected workspaces - Affected users - Workflow impact - Billing impact - Reversibility - Notification behavior - Reason field - Required permission High-risk actions may require: - Typed organization name - Secondary approval - Delayed execution - Audit event - Recovery path === RESPONSIVE ARCHITECTURE === Desktop: Persistent sidebar, dense tables, split views, inspectors, and multi-panel dashboards. Tablet: Collapsed navigation, priority columns, filter drawers, touch-safe actions, and simplified split views. Mobile: - Urgent tasks only - Dedicated entity detail screens - Priority table columns - Card or expandable record views - Simplified bulk actions - Visible tenant and environment context - Protected destructive actions - Mobile-keyboard-safe forms Avoid shrinking desktop tables until they become unreadable. === ACCESSIBILITY REQUIREMENTS === - Semantic landmarks - Logical headings - Accessible navigation - Skip links - Keyboard navigation - Visible focus - Proper table headers - Table captions - Sort-state announcements - Selection-state communication - Accessible filter labels - Persistent form labels - Error relationships - Modal and drawer focus management - Non-color status indicators - Status announcements - Touch-target review - Zoom and reflow - Responsive reading order - Reduced-motion support - Accessible log formatting - Permission explanations - Destructive-action clarity === ANALYTICS EVENT MAP === Event: global_search_used Properties: - entity_type - result_count_bucket - operator_role - scope_type Event: filter_applied Properties: - module - filter_id - operator_role Event: bulk_action_started Properties: - action_type - selected_count_bucket - module - scope_type Event: bulk_action_completed Properties: - action_type - success_count_bucket - failure_count_bucket - excluded_count_bucket Event: permission_changed Properties: - role_id - scope_type - added_count - removed_count - high_risk_change Event: impersonation_started Properties: - operator_role - target_scope_type - approved_duration_bucket Privacy: Do not send names, emails, payment details, secrets, tokens, raw logs, support-note content, or sensitive audit metadata into analytics. === ACCEPTANCE CRITERIA === Tenant Isolation: Given an operator has access only to Organization A, when global search is used, then results from Organization B are not returned or disclosed. Bulk Role Change: Given twenty users are selected, when three users are ineligible, then the interface identifies the exclusions, previews the eligible impact, processes valid records, and reports partial results accurately. Permission Change: Given an administrator adds a high-risk permission, when saving, then the interface shows affected users, scope, inherited changes, operational risk, and the resulting audit event. Impersonation: Given an authorized support operator begins impersonation, when the customer session opens, then a visible banner shows the target user and organization, restricted actions remain unavailable, and Exit Impersonation remains accessible. Destructive Action: Given an administrator suspends an organization, when confirmation appears, then the affected organization, workspaces, users, workflows, billing implications, reversibility, and notification behavior are visible. === REGRESSION TEST MATRIX === Roles: - Super Administrator - Support Agent - Billing Administrator - Organization Administrator - Read-Only Auditor - Unauthorized User Scopes: - Platform - Organization - Workspace - Project - Production - Test Entity States: - Active - Pending - Suspended - Locked - Archived - Deleted Table States: - Loading - Empty - Filtered Empty - Error - Partial Data - Stale Data - Large Result Set - Exporting Bulk Actions: - All Eligible - Partial Eligibility - Partial Failure - Complete Failure - Asynchronous Completion Accessibility: - Keyboard - Screen Reader - Zoom - Reflow - Reduced Motion - High Contrast Where Supported Responsive: - Wide Desktop - Desktop - Laptop - Tablet - Mobile === QA CHECKLIST === Scope: - Verify tenant context. - Verify workspace context. - Verify environment context. - Verify cross-tenant restrictions.

Risk: Hidden permission inheritance Mitigation: Show direct and inherited permissions separately and preview downstream changes. Risk: Unsafe impersonation Mitigation: Require permission, reason, time limit, visible banner, restricted actions, clear exit, and audit logging. Risk: Bulk-action partial failure Mitigation: Validate eligibility, process safely, report per-record outcomes, and support retry where appropriate. Risk: Billing mistake Mitigation: Verify financial rules, effective dates, proration, authorization, confirmation, and audit events. Risk: Sensitive logs are exposed Mitigation: Mask secrets, restrict access, define retention, and review exports. === KNOWN LIMITATIONS === - Authorization rules require backend verification. - Tenant isolation requires security testing. - Billing behavior requires financial and functional validation. - Audit integrity depends on the underlying implementation. - Impersonation requires security and privacy review. - Accessibility requires implementation testing. - Responsive behavior requires device and browser testing. - Analytics must be implemented and validated. - The architecture does not guarantee security, compliance, operational efficiency, or lower support costs. === FINAL INTEGRITY NOTE === All roles, permissions, billing rules, account states, data-retention behavior, deletion behavior, audit semantics, security claims, compliance claims, support privileges, impersonation rules, and operational consequences must be verified before implementation or publication. The admin architecture is designed to improve operational clarity, consistency, safety, and implementation readiness. It does not guarantee security, compliance, productivity, error reduction, support efficiency, or lower operational cost.
