====== Sources ======

**Sources** produce the economy's raw materials: Logs, Grain, Iron Ore, Coal and Oil. A mapped Source stays inactive until its commissioning requirement is delivered, then starts producing as soon as the last crate arrives.

A Source stages its output on its pad. Storage capacity covers pad crates and warehouse stock together, so an uncollected crate can block further production. Restarts top up only a small base stock and clear pad crates; crates dropped elsewhere keep their saved position for one restart (see [[components:restarts|Restarts]]). The Live Map shows a Source's state, its current cycle length and the time to its next crate.

===== Source Types =====

^ Source Type ^ Output Cargo ^ Tier ^ Unlocked By ^
| Forest | Logs | 1 | Available from the start |
| Farm | Grain | 1 | Available from the start |
| Iron | Iron Ore | 2 | Survey Station level 1 |
| Coal | Coal | 2 | Survey Station level 1 |
| Oil | Oil | 3 | Survey Station level 2 |

===== Upgrade Projects =====

Regional [[components:projects|Projects]] improve Sources without changing what they produce.

^ Project ^ Built At ^ Scope ^ Effect on Sources ^
| Maintenance Works | Hub or City | One per region | Production speed +15% / +25% / +35% at level 1/2/3 (each level replaces the last). Capped at 2x base rate. |
| Regional Depot | Hub or City | One per region | Storage +2 / +4 crates at level 1/2 (each level replaces the last). Paused while its Settlement is in unrest. |
| Survey Station | Hub or City | One per region | Gates which tier can appear: level 1 unlocks Tier 2 (Iron Ore, Coal), level 2 unlocks Tier 3 (Oil). |
