Mission Scratchpad — Mosaic Stack Go-Live MVP

Append-only log. NEVER delete entries. NEVER overwrite sections. This is the orchestrator's working memory across sessions.

Original Mission Prompt

Continue Mosaic Stack Go-Live MVP from existing state.
- Mission: Ship Mosaic Stack MVP: operational dashboard with theming, task ingestion,
  one visible agent cycle, deployed and smoke-tested.
- 4 milestones: Dashboard Polish+Theming, Task Ingestion Pipeline,
  Agent Cycle Visibility, Deploy+Smoke Test
- Prior work: MS15-DashboardShell complete (PRs #451-454)
- Design ref: mosaic-stack-website/docs/designs/round-5/claude/01/dashboard.html

Planning Decisions

2026-02-22: Phase-1 Task Breakdown

Baseline assessment:

• Lint: PASS, Typecheck: PASS, Tests: FAIL (9 failures)
• UI Button.test.tsx: 4 fails (old Tailwind class assertions vs new CSS token Button)
• Web page.test.tsx: 5 fails (old widget layout vs Phase 3 rebuild)
• Design system + theming already substantially complete from MS15
• 5 live widgets all use mock data (real data integration is phase-2)
• 4 legacy widgets unused (hardcoded light theme, pre-Phase 3)

Tasks created: MS-P1-001 through MS-P1-004, issue #457, milestone Go-Live-MVP-Phase1 (0.0.16) Estimated total: ~50K tokens

2026-02-23: Phase-4 Completion Summary

• 3/3 tasks done (MS-P4-001 through MS-P4-003)
• Built stack-api and stack-web Docker images locally, pushed to git.mosaicstack.dev/mosaic/ registry
• Fixed root route redirect: removed app/page.tsx that was intercepting / and redirecting to /tasks

• Proxy routing note: Traefik route propagation takes ~5min after service restart; multiple rapid cycles cause intermittent 504s
• Smoke test results: web HTTP 200 (0.19s), API health HTTP 200 (0.10s), dashboard API HTTP 401 (auth required)
• Dashboard verified in browser: all 6 widgets rendering, auth working (User: Jarvis), dark/light theme toggle
• All quality gates green: lint 8/8, typecheck 7/7, test 8/8
