Delta-If-Present Calculations for Missing Signals

Status

NOT_FOUND

Description

The advisory proposed computing "delta if present" values showing what would change if missing signals arrived (TSF-004). This was marked TODO and has not been implemented.

Why Not Implemented

  • The specific "delta-if-present" calculation (TSF-004) for showing hypothetical score changes is not implemented as a standalone feature
  • However, related infrastructure exists in the Policy Determinization module:
    • src/Policy/__Libraries/StellaOps.Policy.Determinization/Models/SignalGap.cs -- models for missing/gap signals
    • src/Policy/__Libraries/StellaOps.Policy.Determinization/Scoring/UncertaintyScoreCalculator.cs -- calculates uncertainty from missing signals
    • src/Policy/__Libraries/StellaOps.Policy.Determinization/Scoring/PriorDistribution.cs -- prior distributions for gap handling
    • src/Policy/__Libraries/StellaOps.Policy.Determinization/DeterminizationOptions.cs -- configuration for determinization behavior
    • src/Policy/StellaOps.Policy.Engine/Simulation/RiskSimulationBreakdown.cs -- risk simulation with breakdown
    • Tests: src/Policy/__Tests/StellaOps.Policy.Engine.Tests/Simulation/RiskSimulationBreakdownServiceTests.cs
  • The Determinization module handles missing signals by computing uncertainty scores but does not project "what would change if signal X arrived" as a delta preview
  • Graph module also tracks missing signals: src/Graph/__Libraries/StellaOps.Graph.Core/ICveObservationNodeRepository.cs
