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:

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