Appendix · Source registry
Connect the systems that already record AI activity. Guardian ingests signals from monitoring, MLOps, ticketing, review, incident, and oversight workflows, then links them into audit-ready evidence records.
Registered intake channels for production signals, review activity, and oversight events. Each source normalizes into the same evidence record — without replacing your existing stack.

How incoming signals become linked, reviewable evidence inside the dossier.
Ingest the metric, alert, review note, or governance event from the source system — via API submission, inbound webhook, or scheduled batch pull.
Guardian maps heterogeneous native metrics into a stable governance schema: drift scores, consistency checks, status changes, and evaluation windows.
Attach the signal to the applicable policy frame, custody handler, and reviewer context so oversight activity stays traceable.
Append the normalized output to the living dossier — timestamped, versioned, and ready for export when scrutiny arrives.
Intake flow
Existing monitoring and evaluation tools → Guardian API or webhook → Normalized governance schema → Evidence records, status tracking, and oversight workflows
Common questions
Choose the intake path that best fits your engineering environment and internal control model.
Send the raw or existing monitoring metrics you already compute. Guardian handles the translation into a normalized governance schema.
Example metrics
Best for
Fast onboarding and pilot deployments
If your team prefers to control the mapping logic internally, you can send Guardian-normalized fields directly.
Example fields
Best for
Teams that want tighter control over internal adapters and mapping rules
Different AI systems produce different native metrics. Guardian translates them into a common governance layer — standardize governance outputs, not model internals.
| Model family | Native signals accepted |
|---|---|
| Binary classification | PSI, recall, disparate impact, demographic parity, equal opportunity gaps |
| Regression and scoring | MAE, RMSE, MAPE, calibration error, score-distribution drift |
| Forecasting | MAPE, SMAPE, forecast bias, residual drift |
| Computer vision | mAP, IoU, embedding drift, confidence drift, per-group recall |
| Ranking and recommenders | NDCG, MAP, MRR, CTR shift, exposure fairness |
| LLM and generative AI | Hallucination rate, groundedness, refusal rate, toxicity rate, task success, prompt drift |
Evidence intake interface
Submit metrics from scheduled evaluations, batch monitoring jobs, or internal reporting pipelines. The API is an evidence intake interface — not a developer dashboard.

}Guardian stores the native metrics, applies the relevant mapping logic, updates governance state, and appends the result to the evidence trail.
Event intake
Use webhooks when governance-relevant events should trigger ingestion or downstream workflows automatically.
Inbound events can either carry metrics directly or notify Guardian to retrieve them from a configured source.
Outbound events connect Guardian with alerting systems, workflow engines, GRC platforms, and internal review queues.

}A first integration can start from aggregate monitoring signals and model metadata — without changing your existing AI stack.
Start with one metric source, one integration path, and one governance workflow.
Guardian is intended to fit engineering environments where reliability, traceability, and controlled rollout matter.
Guardian provides technical evidence infrastructure. It does not determine legal compliance on its own.
The best way to evaluate Guardian is through a focused pilot: one model family, one existing metric source, one lightweight integration, and one evidence workflow.
