# Dependency graph
requires:
  - phase: 03-live-ops-dashboard
    provides: "MetricsCollector, system.metrics/system.events/system.activeRequests RPC handlers, and /health endpoint"
provides:
  - "Live Ops dashboard UI sections for counters, model performance, event stream, active requests, and channels"
  - "Dual refresh cadence: fast (3s) metrics/events/requests and slow (10s) health/channels"
  - "Event stream styling and model metrics summary styling"
affects: [operator-observability, milestone-closure]

# Tech tracking
tech-stack:
  added: []
  patterns:
    - "Targeted section updates via stable DOM IDs"
    - "Split polling cadence for high-churn vs low-churn data"

key-files:
  created: []
  modified:
    - src/gateway/ui/pages/dashboard.js
    - src/gateway/ui/style.css

key-decisions:
  - "Keep vanilla JS page module pattern (render/teardown), no framework migration"
  - "Use two polling timers (3s and 10s) to reduce unnecessary RPC load"
  - "Render newest events at the bottom with auto-scroll for log readability"

patterns-established:
  - "Dashboard section IDs as update boundaries: ops-counters, ops-model-table, ops-events, ops-requests, ops-channels"

# 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`)
