Governance Playground

The Governance Playground (F-17) is an interactive sandbox for testing governance evaluations in real time. These are real evaluations through the actual UCS engine — not simulations.

Starting the Playground

nomotic serve --ui --playground

The playground is available at /ui/playground when the --playground flag is set.

Interface

Configuration Panel

• Archetype selector — choose from all 22 built-in archetypes

• Compliance preset — select strict, standard, ultra_strict, hipaa_aligned, etc.

• Dimension weight overrides — adjust individual dimension weights

• Trust level — set the starting trust score for evaluation

Evaluation Panel

• Action type — the action to evaluate (read, write, delete, etc.)

• Target — the resource being accessed

• Parameters — additional action parameters as JSON

• Evaluate button — run the evaluation and see results

Results Panel

• Verdict — ALLOW, DENY, ESCALATE, MODIFY, or SUSPEND with color indicator

• UCS Score — 0.0–1.0 with visual gauge

• Tier — which tier made the decision (1=deterministic, 2=weighted, 3=deliberative)

• Per-dimension scores — all 14 dimension scores with weights

• Veto dimensions — which dimensions (if any) triggered a veto

Export Config

Export the current playground configuration as a nomotic.yaml file:

POST /v1/playground/export-config

This generates a ready-to-use configuration file with the archetype, preset, and weight overrides you configured in the playground.
