# EPSS Ingest Perf Harness
Sprint: `SPRINT_3410_0001_0001_epss_ingestion_storage` (Task `EPSS-3410-013A` / `EPSS-3410-014`)
## Local Run
Prereqs:
- Docker available to Testcontainers
- .NET 10 SDK (preview, per repo `global.json`)
Run (310k rows, default):
```bash
dotnet run --project src/Scanner/__Benchmarks/StellaOps.Scanner.Storage.Epss.Perf/StellaOps.Scanner.Storage.Epss.Perf.csproj -c Release -- --rows 310000 --output bench/results/epss-ingest-perf.json
```
Options:
- `--rows <int>`: dataset rows (default: `310000`)
- `--seed <hex>`: 64-bit seed in hex without `0x` (default: `5EED20251219`)
- `--model-date <YYYY-MM-DD>`: model date (default: today UTC)
- `--postgres-image <image>`: Postgres image (default: `postgres:16-alpine`)
- `--output <path>`: output JSON path
## Output Format
The harness writes a single JSON file:
- `tool`: `{ name, schema }`
- `dataset`: `{ modelDate, rows, seed, compressedSha256, decompressedSha256, modelVersionTag, publishedDate, compressedBytes, decompressedBytes }`
- `environment`: `{ os, framework, processArchitecture, postgresImage }`
- `timingsMs`: `{ datasetGenerate, containerStart, migrations, writeSnapshot, total }`
- `result`: `{ importRunId, rowCount, distinctCveCount }`
