Description

As a swatch developer, I need to update MeasurementNormalizer in swatch-metrics-hbi to use the centralized CoreSocketNormalizer so that events sent to Kafka have values normalized consistently with swatch-tally.

Technical Details

File: swatch-metrics-hbi/src/main/java/.../hbi/events/normalization/MeasurementNormalizer.java

Before:

• Contains duplicated normalization logic
• May produce different values than FactNormalizer in edge cases

After:

• Build NormalizationContext from HBI event data
• Call CoreSocketNormalizer.normalize(context)
• Use returned NormalizedMeasurements in SWatch event

Data Flow

HBI Event (Kafka)
    |
    v
swatch-metrics-hbi
    |
    v
FactNormalizer (classification only, NOT cores/sockets)
    |
    v
MeasurementNormalizer
    |
    v
CoreSocketNormalizer.normalize() <- swatch-common-instances
    |
    v
SWatch Event (Kafka) with normalized cores/sockets

Acceptance Criteria

• MeasurementNormalizer builds NormalizationContext from event data
• MeasurementNormalizer calls CoreSocketNormalizer.normalize()
• Old normalization methods removed
• All existing MeasurementNormalizer tests pass without modification
• SWatch events contain same normalized values as before
