- [x] `@q[ambiguous]` Line 13: "Commanders: Alexander the Great vs. Darius III" - what does "III" mean in this context?
> III is the regnal number — Darius III Codomannus was the third Persian king named Darius. Standard historical convention.
- [x] `@q[ambiguous]` Line 25: "Darius III was later murdered by his own satrap Bessus (330 BCE)" - what does "III" mean in this context?
> Same as above — III is the regnal number for Darius III. Standard convention.
- [x] `@q[stale]` Line 26: "Marked the end of the Achaemenid dynasty after ~220 years [^2]" - Heckel source from 2008 may be outdated, is this still accurate?
> Heckel (2008) remains a standard reference. The end of the Achaemenid dynasty in 330 BCE is undisputed historical fact. Still accurate.
