# DSSE+Rekor Batch Size Benchmarking Tool (stella-attest-bench)

## Status
NOT_FOUND

## Description
The advisory proposed a dedicated CLI benchmarking tool (stella-attest-bench) to sweep DSSE envelope batch sizes against Rekor and determine optimal defaults. While the underlying DSSE and Rekor infrastructure exists, no dedicated benchmarking/experiment tool was implemented.

## Why Not Implemented
- No dedicated `stella-attest-bench` CLI tool found
- The underlying DSSE and Rekor infrastructure is fully implemented in `src/Attestor/__Libraries/StellaOps.Attestor.ProofChain/`:
  - `Signing/DsseEnvelope.cs`, `DsseSignature.cs` -- DSSE envelope support
  - `Rekor/EnhancedRekorProofBuilder.Build.cs`, `EnhancedRekorProofBuilder.Validate.cs` -- Rekor integration
  - `Rekor/RekorInclusionProof.cs` -- Rekor inclusion proofs
- The Bench module (`src/Bench/StellaOps.Bench/`) has benchmarking infrastructure (LinkNotMerge scenario runner, JSON/Prometheus reporting) but no DSSE batch size sweeping tool
- The Bench infrastructure (BenchmarkConfig, BenchmarkJsonWriter, PrometheusWriter) could serve as a foundation for a DSSE batch benchmark
- This is a low-priority optimization tool; the DSSE+Rekor pipeline works but batch size tuning requires a dedicated experiment harness
