Status

PARTIALLY_IMPLEMENTED

Description

The TTE metric (measuring time from finding open to first proof rendered) is not implemented in the frontend or backend.

Module

Telemetry

What's Implemented

  • TTE metrics collection: src/Telemetry/StellaOps.Telemetry.Core/StellaOps.Telemetry.Core/TimeToEvidenceMetrics.cs
  • Percentile exporter: src/Telemetry/StellaOps.Telemetry.Core/StellaOps.Telemetry.Core/TtePercentileExporter.cs (P50/P90/P99)
  • Scan completion integration: src/Telemetry/StellaOps.Telemetry.Core/StellaOps.Telemetry.Core/ScanCompletionMetricsIntegration.cs
  • Attestation metrics: src/Telemetry/StellaOps.Telemetry.Core/StellaOps.Telemetry.Core/Metrics/AttestationMetrics.cs
  • DI registration: src/Telemetry/StellaOps.Telemetry.Core/StellaOps.Telemetry.Core/TelemetryServiceCollectionExtensions.cs
  • Baseline tracking: src/__Tests/__Benchmarks/baselines/ttfs-baseline.json

What's Missing

  • Frontend visualization of TTE metrics (dashboard/chart in Web UI)
  • TTE trend visualization over time
  • Per-finding TTE breakdown in the UI

Implementation Plan

  • Add TTE dashboard widget to Web UI
  • Show TTE percentile trends over time
  • Include TTE metric in finding detail view
