Mission Data Model & Schema Contracts

Purpose: Formal definition of tabular data contracts, feature schemas, prediction structures, and configuration schemas.

---

1. Pandera Tabular Schemas (core/schemas.py)

Every tabular dataset passing through a pipeline boundary is validated against strict Pandera DataFrameModel definitions:

classDiagram
    direction TB

    class Schema {
        +check(data: DataFrame) DataFrame$
    }

    class InputsSchema {
        +UInt32 instant (Index)
        +DateTime dteday
        +UInt8 season
        +UInt8 yr
        +UInt8 mnth
        +UInt8 hr
        +UInt8 holiday
        +UInt8 weekday
        +UInt8 workingday
        +UInt8 weathersit
        +float temp
        +float atemp
        +float hum
        +float windspeed
    }
    InputsSchema --|> Schema : inherits

    class TargetsSchema {
        +UInt32 instant (Index)
        +UInt32 cnt
    }
    TargetsSchema --|> Schema : inherits

    class OutputsSchema {
        +UInt32 instant (Index)
        +UInt32 prediction
    }
    OutputsSchema --|> Schema : inherits

    class FeatureImportancesSchema {
        +str feature
        +float importance
    }
    FeatureImportancesSchema --|> Schema : inherits

    class SHAPValuesSchema {
        +float base_values
        +float values
    }
    SHAPValuesSchema --|> Schema : inherits

2. API & Streaming Payloads (controller/kafka_app.py)

PredictionRequest

Encapsulates an incoming payload submitted via HTTP POST /predict or consumed from Kafka:

{
  "input_data": {
    "instant": [1],
    "dteday": ["2011-01-01 00:00:00"],
    "season": [1],
    "yr": [0],
    "mnth": [1],
    "hr": [0],
    "holiday": [0],
    "weekday": [6],
    "workingday": [0],
    "weathersit": [1],
    "temp": [0.24],
    "atemp": [0.2879],
    "hum": [0.81],
    "windspeed": [0.0]
  }
}

PredictionResponse

Encapsulates the predicted target value returned to the client:

{
  "result": {
    "prediction": [16]
  }
}

3. Cryptographic Signature Payload (utils/signers.py)

The InferSigner generates a SHA-256 hash attesting to prediction inputs and outputs:

Signature: 8f9b3e1c2a4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f
