Backward launch timeline calculator
Calendar-day model: materials and approvals start together; production waits for both. All later stages are sequential. No holidays, closures or booking cutoffs are calculated.

Results
Durations are user assumptions, not Yuchen lead times. Confirm parallel work is feasible. Add project-specific dependencies outside this simplified model.
