Output directory unavailable

The requested output already exists, or the exporter failed to create it when publishing. Existing exports are never overwritten; publication stops.

#Common causes

• The destination was reused, another export claimed it, or filesystem permissions prevent creating it.

#Fixes

• Choose a new, writable --output directory and retry; give concurrent exports distinct destinations.

• Code: ARA-EXP-OUT-001 (slot 8018)

• Constant: export::OUT_001
