1How It Works

Scenario Registry
   -> Synthetic Data Generator (seeded RNG, IN/US)
   -> Mutation Library (identity / tax / matching / bank / document)
   -> Validation Engine (arithmetic, tax, 3-way match)
   -> Document Renderer (PDF / PNG / CSV / XLSX / JSON / EML / TXT)
   -> API Layer (/generate, /generate/batch, /scenario, /document/:id)
   -> Ground truth: expected_exceptions, expected_actions,
      human_approval_required, dangerous_actions_that_must_not_be_automatic

2API Endpoints

Endpoint Purpose
POST /generate Generate a single document in any export format
POST /generate/batch Generate many documents/scenario runs at once (max 200)
POST /scenario Run a named scenario end-to-end and get the full ground-truth bundle
GET /scenario List all available scenarios
GET /scenario/:run_id Retrieve a previously run scenario bundle
GET /document/:test_id?format=pdf Retrieve/re-render a previously generated document

Note: Every generated artifact carries a visible DUMMY / SYNTHETIC TEST DOCUMENT marker and synthetic: true metadata. Nothing produced here is a real financial record.
