Add Policy DSL Validator, Schema Exporter, and Simulation Smoke tools
- Implemented PolicyDslValidator with command-line options for strict mode and JSON output.
- Created PolicySchemaExporter to generate JSON schemas for policy-related models.
- Developed PolicySimulationSmoke tool to validate policy simulations against expected outcomes.
- Added project files and necessary dependencies for each tool.
- Ensured proper error handling and usage instructions across tools.

Link-Not-Merge VEX Bench

Measures synthetic VEX observation ingest and event emission throughput for the Link-Not-Merge program.

Scenarios

config.json defines workloads with varying statement density and tenant fan-out. Metrics captured per scenario:

  • Total latency (ingest + correlation) and p95/max percentiles
  • Correlator-only latency and Mongo insert latency
  • Observation throughput (observations/sec)
  • Event emission throughput (events/sec)
  • Peak managed heap allocations

Running locally

dotnet run \
  --project src/StellaOps.Bench/LinkNotMerge.Vex/StellaOps.Bench.LinkNotMerge.Vex/StellaOps.Bench.LinkNotMerge.Vex.csproj \
  -- \
  --csv out/linknotmerge-vex-bench.csv \
  --json out/linknotmerge-vex-bench.json \
  --prometheus out/linknotmerge-vex-bench.prom

The benchmark exits non-zero if latency thresholds are exceeded, observation or event throughput drops below configured floors, allocations exceed the ceiling, or regression ratios breach the baseline.
