Phase 3 Plan 2: Live Ops Dashboard UI Summary

Extended the existing dashboard with live counters, model performance telemetry, event stream, and active request visibility, backed by Phase 3 Plan 1 RPC endpoints.

Performance

• Summary date: 2026-02-13
• Tasks: 2/2 (implementation + closure/verification)
• Files modified: 2

Accomplishments

• Implemented dashboard sections for core counters, model metrics table, event stream, active requests, and channels
• Wired RPC calls to system.metrics, system.events, system.activeRequests, system.health, and system.channels
• Added 3-second fast refresh for dynamic ops data and 10-second slow refresh for health/channel state
• Added event stream and model summary styling in shared gateway UI stylesheet

Task Commits

Implementation was already present in commit history and is now formally closed with planning artifacts:

1. Task 1: Extend dashboard page with live ops sections - c3ca3f3 (feat)
2. Follow-up style cleanup - 6090508 (style)

Files Created/Modified

• src/gateway/ui/pages/dashboard.js - Live ops dashboard structure, polling, and targeted section updates
• src/gateway/ui/style.css - Event stream and model metrics summary styles

Verification

Automated checks run during this closure:

• pnpm typecheck ✅
• pnpm build ✅
• pnpm test:run ✅ (1590/1590 passed)

Manual browser verification (visual sanity check) remains recommended as a final operator check.

Deviations from Plan

No functional deviations. This summary was backfilled after implementation had already landed.

Issues Encountered

None

User Setup Required

None

Next Phase Readiness

• Phase 3 is complete from an implementation and automated validation perspective
• Milestone artifacts are now synchronized (STATE.md, ROADMAP.md, REQUIREMENTS.md)
