Embargo enforcement: market + transfers (P3.1B)
2026-03-22
- Market order book now hides orders from embargoed nations/alliances — both sides of an embargo lose visibility into each other's orders (symmetric).
- Tick-engine market matching skips trades between embargoed nation pairs, preventing embargoed orders from filling server-side.
- Nation-to-nation resource/cash transfers are blocked (`TRANSFER_EMBARGO_BLOCKED`, HTTP 409) when any active embargo covers the sender or recipient.
- Alliance bank deposits and withdrawals are blocked (`InternalSanctionBlocked`) for members whose own alliance has imposed an internal sanction (nation-level embargo) on them.
