Overview

This repository demonstrates a reliability first architecture for AI assisted training debrief generation inside secure simulator environments.

The goal is not to build a large model system. The goal is to demonstrate how AI outputs can be made traceable, constrained, and auditable in environments where correctness matters.

The repository includes

1. Architecture documentation
2. A working demo pipeline
3. Schema constrained outputs
4. Output validation
5. Evaluation metrics

Design Goals

This project demonstrates several key system design goals common in reliable AI infrastructure.

Reliable outputs
Traceable model behavior
Schema constrained generation
Deterministic evaluation
Separation between data, model logic, and validation

These principles ensure the AI component behaves predictably within a controlled system.

System Overview

The system demonstrates a reliability first pipeline for AI assisted debrief generation.

Pipeline architecture

Mission Data
→ Structured Event Mapping
→ Transcript Processing
→ Objective Detection
→ Constrained Debrief Generation
→ Schema Validation
→ Evaluation and Scoring

Each layer isolates model behavior so every output can be traced back to source data.

Option 1
Download ZIP from the green Code button.

Option 2
Clone using git

git clone https://github.com/PatrickImperato/aireliabilitydebrief.git
cd aireliabilitydebrief

---

Create a Python environment

python3 -m venv .venv
source .venv/bin/activate

When activated your terminal will show

(.venv)

---

Install dependencies

pip install -r requirements.txt

The demo only requires the jsonschema package.

---

Generate a debrief

Run the generator script.

python3 demo/src/generateDebrief.py demo/data/sampleMissionLog.json demo/data/sampleTranscript.json demo/data/outputDebrief.json

The generated output file appears here

demo/data/outputDebrief.json

---

Validate the output

Validate the generated JSON using the schema.

python3 demo/src/validateJson.py demo/schemas/debrief.schema.json demo/data/outputDebrief.json

Expected output

Validation passed

---

Score the output

Compare the generated output with the expected reference output.

python3 demo/src/scoreOutput.py demo/data/expectedDebrief.json demo/data/outputDebrief.json

Example output

TP 2
FP 1
FN 1
Precision 0.667
Recall 0.667
F1 0.667

Why This Approach Exists

AI systems can generate convincing text that is incorrect.

In secure environments such as training simulators, defense systems, or regulated workflows, outputs must be reliable and auditable.

This repository demonstrates a reliability first architecture that controls model outputs using structured constraints.

Key controls include

Template constrained outputs
Schema validation gates
Traceable source inputs
Deterministic evaluation metrics

In this system the AI component becomes one controlled stage inside a reliable pipeline.

---

Key Design Principles

Template First Outputs

AI generation is constrained to predefined structures so outputs remain predictable.

Schema Validation

Every output must pass JSON schema validation before it can move forward.

Traceability

Every claim in the debrief references the underlying transcript or mission event.

Evaluation Layer

Outputs are automatically scored against expected references to detect regressions.

---

Threat Model

Potential failure modes addressed

Hallucinated claims
Unstructured output drift
Missing traceability
Silent regressions in output quality

Controls implemented

Schema validation
Deterministic scoring
Explicit source references

Evaluation Plan

Evaluation focuses on reproducibility and regression detection.

Metrics include

Precision
Recall
F1 score

Why Reliability Matters

Most AI discussions focus on model capability.
Production systems fail for different reasons.

Common failure modes include:

Unstructured outputs that downstream systems cannot consume
Silent hallucinations that appear plausible but incorrect
Lack of evaluation pipelines
No rollback or rollout controls

This architecture focuses on building reliability layers around the model so outputs can be validated, scored, and governed before reaching users.
