# Operational Logistics, Contracts, and Handoffs
Logistics exists to support operations: movement of equipment, documents, sources, evidence, personnel, and time-sensitive material.

## Contract state model

Created → Accepted → In Transit → Delivered, Breached, Expired, or Canceled.

- The issuer locks the reward and cargo.
- The courier locks collateral.
- State transitions are server-authoritative and atomic.
- Intact delivery returns collateral and releases the reward.
- Breach or expiration applies the defined settlement without human ambiguity.
- Fees are sinks; reward and collateral movement are transfers or locks, not currency destruction.

## Physical and access rules

- Cargo is represented by a tamper-evident lockbox with volume and mass.
- Public perimeter receptacles separate delivery from private structural access.
- Accessibility is validated before posting and rechecked while the contract is active.
- Obstruction after acceptance triggers safe resolution rather than automatic courier loss.
- Provenance and handoff records use UTC timestamps and immutable state history.
