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
