Sell timing should be judged against route maturity, processing state, and market conditions together
The latest official trade-related notices make one thing clearer: market rules and service conditions can move, so this wiki now treats selling as a later-layer optimization tied to build certainty and account stability, not as an always-on default behavior.
- If a piece might still serve the current build, the next build, or a backup route, it is not really "extra" yet.
- `D / E / I` states matter because processed gear has already absorbed resources that may need to be recovered or justified first.
- Mailbox reading is part of trade literacy because the item's state changes after it leaves the ship list.
