Dry-Run Policy Application API

Status

IMPLEMENTED

Description

Backend support for dry-run policy application with diff preview and rollback plan generation. Not yet implemented.

Why Marked as Dropped (Correction)

FINDING: Policy simulation / dry-run IS implemented. The following exist:

  • src/Policy/StellaOps.Policy.Registry/Services/PolicySimulationService.cs -- core simulation service
  • src/Policy/StellaOps.Policy.Registry/Services/IPolicySimulationService.cs -- interface
  • src/Policy/StellaOps.Policy.Registry/Services/BatchSimulationOrchestrator.cs -- batch simulation support
  • src/Policy/StellaOps.Policy.Registry/Services/IBatchSimulationOrchestrator.cs -- interface
  • src/Policy/StellaOps.Policy.Registry/Testing/PolicyRegistryTestHarness.cs -- test harness
  • Tools library: src/__Libraries/StellaOps.Policy.Tools/PolicySimulationSmokeCommand.cs, PolicySimulationSmokeModels.cs, PolicySimulationSmokeApp.cs
  • Web UI dry-run support: setup wizard includes dry-run functionality per src/Web/StellaOps.Web/src/app/features/setup-wizard/
  • Database migration support: src/__Libraries/StellaOps.Infrastructure.Postgres/Migrations/MigrationRunner.cs has dry-run mode

Implementation Details

  • Simulation service: src/Policy/StellaOps.Policy.Registry/Services/PolicySimulationService.cs
  • Batch orchestrator: src/Policy/StellaOps.Policy.Registry/Services/BatchSimulationOrchestrator.cs
  • Smoke test tools: src/__Libraries/StellaOps.Policy.Tools/PolicySimulationSmoke*.cs
  • Test harness: src/Policy/StellaOps.Policy.Registry/Testing/PolicyRegistryTestHarness.cs

E2E Test Plan

  • Verify policy simulation produces expected diff output
  • Test batch simulation across multiple policies
  • Validate dry-run mode prevents actual policy application

Source

  • Feature matrix scan

Notes

  • Module: Policy
