The Logistics State Machine (LSM) is the formal lifecycle of a DLA under PAEE. States are named, transitions are gated by events, and illegal jumps are simply not in the machine — they are bugs if an implementation allows them.
Example state families (product-aligned)
- Draft / listed — identity exists, no commercial hold yet
- Booked — parties accepted; J1USD hold attached
- In custody — a traveler or Host has accepted after inspection
- In transit — flight or local hop underway
- Hub hold — Host storage between legs
- Delivered — recipient confirmation; settlement release
- Refused / cancelled / disputed — terminal or exception branches
Transition rules
You cannot mark delivered from listed without custody events. You cannot attach a second conflicting final recipient without a defined split. Multi-leg shipments are compositions of LSM segments on the same DLA, not a new informal chat process.
Why this matters in disputes
Support and participants reconstruct the path through the machine using photos and timestamps as event payloads. A well-typed LSM is how J1USD escrow conditions stay programmable instead of discretionary.
