PRD: Mosaic Stack Dashboard & Platform Implementation

Metadata

• Owner: Jason Woltje
• Date: 2026-02-22
• Status: in-progress
• Best-Guess Mode: true

Problem Statement

The Mosaic Stack web UI has a basic navigation and simple widget-based dashboard that doesn't match the production-ready design vision. The reference design (dashboard.html) defines a comprehensive command center UI with sidebar navigation, topbar, terminal panel, and multiple page layouts. The current implementation uses mismatched design tokens (raw Tailwind colors vs CSS variables), has no collapsible sidebar, no global terminal, and lacks the polished design system from the reference.

Objectives

1. Implement the dashboard.html reference design as the production UI foundation
2. Establish a consistent CSS design token system that supports multiple themes
3. Build a responsive, accessible app shell with collapsible sidebar and full-width header
4. Create a theme system supporting installable theme packages
5. Build all dashboard pages (Dashboard, Projects, Workspace, Kanban, Files, Logs, Settings, Profile)
6. Implement real backend integration (no mock data)
7. Support multi-tenant configuration with RBAC
8. Implement federation (master-master and master-slave)
9. Build global terminal, project chat, and master chat session
10. Configure telemetry with opt-out support

Scope

In Scope (MS16+MS17 — Pages & Data Integration)

This is the active mission scope. MS16 (Pages) and MS17 (Backend Integration) are combined because the backend API modules already exist — the work is primarily frontend page creation and API wiring.

1. Projects list page with CRUD (wire to existing /api/projects)
2. Project workspace/detail page (wire to /api/projects/:id, /api/tasks, /api/runner-jobs)
3. Kanban board page with status-based columns (wire to existing /api/tasks)
4. File Manager page with tree/list view and CRUD (wire to existing /api/knowledge)
5. Logs & Telemetry page with log viewer and filtering (wire to /api/runner-jobs, job steps, events)
6. Settings root/index page linking to existing subpages
7. Custom 404 page for unknown routes
8. Wire /tasks page to real API data (currently mock)
9. Wire /calendar page to real API data (currently mock)
10. Wire /knowledge pages to real API data (currently mock)

22. Agent task mapping configuration: system-level defaults, user-level overrides (MS22)
23. Telemetry: opt-out, customizable endpoint, sanitized data (MS22)
24. File manager with WYSIWYG editing: system/user/project levels (MS18)
25. User-level and project-level Kanban with filtering (MS18)

Out of Scope

1. Mobile native app
2. Third-party marketplace for themes/widgets (initial implementation is local package management only)
3. Mobile native app deployment targets
4. Calendar system redesign (existing calendar implementation is retained)

User/Stakeholder Requirements

1. The jarvis user must be able to log into mosaic.woltje.com via Authentik as administrator with access to all pages
2. A standard jarvis-user must operate at a lower permission level
3. A break-glass user must have access without Authentik authentication
4. All pages must be navigable without errors (no 404s from sidebar links)
5. Light and dark themes must work across all pages and components
6. Sidebar must be collapsible with open/close button; hidden by default at small breakpoints
7. Hamburger button visible at lower breakpoints for sidebar control
8. The Mosaic Stack logo icon must be the site-wide loading spinner
9. No mock data — all data pulled from backend APIs

Full Project (All Milestones)

52. jarvis user logs in via Authentik, has admin access to all pages
53. jarvis-user has standard access at lower permission level
54. Break-glass user has access without Authentik
55. Three Mosaic Stack instances on Portainer with federation testing

57. No errors during site navigation
58. API documented via Swagger with proper auth gating
59. Telemetry working locally with wide-event logging
60. Mosaic Telemetry properly reporting to telemetry endpoint

Constraints and Dependencies

1. Next.js 16 with App Router — all pages use server/client component patterns
2. Tailwind CSS 3.4 — design tokens must integrate with Tailwind's utility class system
3. BetterAuth for authentication — must maintain existing auth flow
4. Authentik as IdP at auth.diversecanvas.com — must remain operational
5. PostgreSQL 17 with Prisma — all settings stored in DB
6. Portainer for deployment — 3 instances needed for federation testing
7. packages/ui is shared across apps — changes affect all consumers
8. Backend API modules already exist for all page data needs — no new API endpoints required for MS16+MS17 scope

Risks and Open Questions

1. Risk: Pages need to match the design system established in MS15. Inconsistency would degrade UX. Mitigation: Use existing design tokens and shared components exclusively. RESOLVED — All MS16+MS17 pages use design tokens consistently.
2. Risk: Kanban drag-and-drop adds complexity and potential for state bugs. Mitigation: Use a proven DnD library. RESOLVED — @hello-pangea/dnd selected (maintained fork of react-beautiful-dnd, better TS support). Optimistic updates with rollback on failure.
3. Risk: Mock data elimination may reveal backend API gaps or mismatches. Mitigation: Audit each API response shape against page needs during implementation. RESOLVED — All 3 mock-data pages wired successfully. No API gaps found.
4. Open: Exact task status values for Kanban columns RESOLVED — TaskStatus enum: NOT_STARTED, IN_PROGRESS, PAUSED, COMPLETED, ARCHIVED (5 columns).
5. Open: Whether Workspace page should require project selection or show a default view RESOLVED — Shows project selector when no project param, workspace detail when ?project=id.
6. Open: File Manager page — should it be a direct mapping of Knowledge entries or a separate file abstraction? RESOLVED — Direct mapping to Knowledge entries via /api/knowledge. API shape matches file manager needs.

Assumptions

1. ASSUMPTION: Header spans full width including above sidebar area. The logo is in the header, not the sidebar. Rationale: User explicitly stated "The logo will NOT be part of the sidebar."
2. ASSUMPTION: Sidebar footer user card navigates to Profile page. Rationale: Matches reference design behavior.
3. ASSUMPTION: Initial implementation supports dark/light from reference design. Multi-theme package system is a future milestone. Rationale: Foundation must be solid before extensibility.
4. ASSUMPTION: MS16 and MS17 are combined into a single mission because 19 backend API modules already exist with real Prisma business logic. The remaining work is primarily frontend page creation and API wiring. Rationale: Backend audit on 2026-02-22 confirmed all required endpoints are implemented.
5. ASSUMPTION: File Manager page maps to Knowledge entries rather than a separate file system abstraction. Rationale: /api/knowledge provides full CRUD + search which matches file manager needs. Can be extended later if needed.
6. ASSUMPTION: Theme packages are code-level TypeScript files (not runtime-installable npm packages). Each theme exports CSS variable overrides. Rationale: Keeps the system simple for MS18; runtime package loading can be added in a future milestone.
7. ASSUMPTION: WYSIWYG editor uses Tiptap (ProseMirror-based, headless). Rationale: Headless approach integrates naturally with the CSS variable design system, excellent markdown import/export, TypeScript-first, battle-tested.
8. ASSUMPTION: MS18 includes WYSIWYG editing for knowledge entries and Kanban filtering enhancements in addition to themes and widgets. These were originally listed separately but are grouped into MS18 per PRD scope items 24-25. Rationale: All are frontend-focused enhancements that build on the existing page infrastructure.
