"""Task 5 (user decision 2026-10-21): no pattern-station data exists. Create a
|
|
PLACEHOLDER pattern table at 2 m segments over the modelled range 4+745..5+480,
|
|
cycling the six pattern names. Every row is marked '임의 배정 (placeholder)'.
|
|
The table is an editable CSV: replace the 'pattern' column later and rebuild.
|
|
Output: data/pattern_zones_placeholder.csv (created only if absent; never overwritten)."""
