Create a BPMN 2.0 swimlane diagram of the export workflow for [OriginPort] at [CompanyName], covering shipper pickup to vessel load confirmation. Lanes must include: Shipper, Drayage/Trucker, Yard/Gate, Terminal Operations, Customs/Broker, Ocean Carrier, and Control Tower. Capture events (cut-off, VGM, customs release), gateways (clearance pass/fail), and service-level timers (e.g., gate appointment windows). Explicitly model exception paths (rollover, no VGM, scan hold) and required data objects (booking number, EDI 301/315/322, VGM file).
Output format:
BPMN XML (valid, minimal) followed by a legend of symbols.
A Markdown RACI for each activity (R/A/C/I across [RolesList]).
A risk register table listing failure modes (FMEA: severity, occurrence, detection) and mitigations.
Conclude with the three highest-value workflow optimizations, each tied to [PrimaryMetric] (e.g., gate turn time, TEU dwell) and quantified targets for [Timeframe].
