Heath Tree Extraction Rig — Grounding Rules

The 18 i;lt / i;gt records added to log.csv (lines 145–162) for treepuller.json. Each row turns one measured channel into one quark; the tree then reacts to the quark alone. Ref numbers match the balloon callouts on Dwg 003-A.

Where the numbers live. Units and real numbers appear only here — the world model says stat overload → stop pulley, this sheet says 25 kN is overload. Recalibrating the rig means editing this table, never the tree.

Not repeated here. The winch battery reuses the existing battery_% rules already in the pool (stat low / stat empty / stat full, log.csv lines 119–121). Thresholds are plausible placeholders for a small-truck electric winch (~25 kN line, ~1–3 t hitch) and need calibration against real hardware.
