Theodolite#

Theodolites measure angles using optical alignment. Their behavior is stable but sensitive to environmental and mechanical assumptions.

Dimensional Core (SET)#

• Spin: not relevant
• Elec: optional digital readout
• Temp: affects mechanical expansion

Why Yellow‑Zone#

Direct measurement is strong, but mechanical alignment and environmental factors introduce mixed‑regime behavior.

Regime Notes#

• pos‑regime: stable mount, clear line of sight
• Q‑regime: heat shimmer, vibration
• neg‑regime: unstable platforms, rapid motion

Alignment Notes#

Needs explicit environmental and mechanical boundaries.
