Changelog entry
Interception mechanics + escorts (P4.4C)
2026-03-25
- Added `POST /api/transfers/intercept` for convoy interception attempts; attempts are only allowed for nations in an active war with the convoy sender and spend configurable Command on each valid attempt.
- Interception odds are deterministic and config-driven: `attackerNavalStrength / (attackerNavalStrength + escortStrength + baseDefense)`, with a seeded roll from world seed + tick + convoy id.
- Successful interceptions steal a deterministic partial share of cargo (between configurable 30%-60% based on attacker strength ratio), and the remaining cargo stays in transit to the recipient.
- Escort strength now applies an upfront munitions upkeep cost at convoy creation for the full transit duration.
