## Verdict
Approved as the current canonical Field Command operational mark direction.

v001 better preserves the Dobsonian Institute visual DNA through a simplified diamond boundary and centered threshold/door form. It reads clearly as a threshold/door at small scale. The restrained base line works as grounding/procedural visual language. It avoids becoming a generic faction badge, military patch, occult symbol, or abstract emblem.

## Keep
- simplified diamond boundary
- centered vertical threshold/door form
- strong negative space
- restrained base line beneath the threshold form
- no internal text
- no extra symbols, glyphs, stars, laurels, wings, skulls, numbers, slogans, or decorative insignia
- document-family reference sheet presentation
- small-scale application examples on the sheet

## Refine
- future unit sheets: use this mark sparingly and at small scale only
- ultra-small UI contexts may use threshold/door-only variant when diamond boundary would not remain legible

## Notes
Current canonical operational mark direction for Field Command. Promoted to `03-selected/` as the approved reference entry. v002 preserved in `02-generated/` as exploration only.
