+# Mission Manifest — Mosaic Stack Go-Live MVP
+
+> Persistent document tracking full mission scope, status, and session history.
+> Updated by the orchestrator at each phase transition and milestone completion.
+
+## Mission
+
+**ID:** mosaic-stack-go-live-mvp-20260222
+**Statement:** Ship Mosaic Stack MVP: operational dashboard with theming, task ingestion, one visible agent cycle, deployed and smoke-tested. Unblocks SagePHR, DYOR, Calibr, and downstream projects.
+**Phase:** Intake
+**Current Milestone:** —
+**Progress:** 0 / 4 milestones
+**Status:** active
+**Last Updated:** 2026-02-22 23:35 UTC
+
+## Success Criteria
+
+1. Dashboard loads reliably at mosaic.woltje.com with theming system operational
+2. Task/status ingestion: create/update flow persists records visible in UI
+3. One agent job runs from queued to completion/failure with status transitions visible
+4. Stack deployed via Coolify, auth + dashboard reachable, smoke checks passing
+5. Design reference: `mosaic-stack-website/docs/designs/round-5/claude/01/dashboard.html`
+
+## Prior Work (MS15-DashboardShell — Complete)
+
+The Feb 22 agent completed the dashboard shell foundation:
+
+- PR #451: Design System & App Shell (tokens, layout, sidebar, topbar, responsive, spinner)
+- PR #452: Shared Components & Terminal Panel (ui token alignment, card/badge/button, metrics, terminal)
+- PR #453: Dashboard Page (widget grid, activity feed, command palette, notifications)
+- PR #454: Design system reference docs
+
+This mission continues from that foundation.
