## When to Use

Use this skill in quantitative trading firms, broker adapters, and market data distribution hubs to enforce vendor contractual licensing restrictions (Bloomberg B-PIPE, Refinitiv ELEKTRON, S&P Capital IQ). Exchanges and market data vendors impose strict licensing boundaries distinguishing **Internal Research**, **Non-Display Automated Trading**, and **External Redistribution**. Unauthorized external redistribution or non-display trading without explicit licensing triggers severe financial audit penalties from exchanges.

## Prerequisites

- Vendor contract definitions (`vendor_name`, `license_tier`, `allowed_use_cases`, `is_redistribution_allowed`, `is_non_display_allowed`, `max_concurrent_entitlements`).

- Access request payload (`requested_by_system`, `use_case_type`, `is_external_redistribution`, `active_user_count`).

## Workflow

1. **Vendor License Entitlement Audit**:

- Verify `use_case_type` against contract `allowed_use_cases`.

2. **Non-Display & Redistribution Interception**:

- If `is_external_redistribution` is True and contract `is_redistribution_allowed` is False $\implies$ Issue `REDISTRIBUTION_LICENSING_VIOLATION`.

- If `use_case_type == "NON_DISPLAY_TRADING"` and `is_non_display_allowed` is False $\implies$ Issue `NON_DISPLAY_LICENSING_VIOLATION`.

3. **Concurrency Headroom Audit**:

- If `active_user_count > max_concurrent_entitlements` $\implies$ Issue `CONCURRENCY_CAP_EXCEEDED`.

4. **Audit Report Generation**: Output structured `VendorUsageAuditReport`.

## Common Pitfalls

- **Publishing Internal Benchmarks Externally**: Exposing raw or derived Bloomberg/Refinitiv quotes on client-facing websites without an External Redistribution License.

- **Un-licensed Algorithmic Trading**: Deploying automated HFT bots on desktop-only terminal subscriptions without non-display trading enterprise licenses.

- **Ignoring Concurrent Seat Caps**: Exceeding concurrent terminal or API user entitlement caps during market volatility spikes.

## Verification

- Instantiate `VendorUsageRestrictionEngine`. Register Bloomberg B-PIPE contract (Non-display=True, Redistribution=False, Seat cap=10). Submit a request for internal HFT bot execution. Verify request is `APPROVED`. Submit a request to publish raw quotes on an external portal. Verify engine flags `REDISTRIBUTION_LICENSING_VIOLATION` and returns `DENIED`.

- Run `python scripts/test_vendor_usage_tracking.py`.
