Report #157 — 4-person / 2-3kW house sized on the stewards_ark ladder: L1 half-life-0, L2 displaced-dependency 7-12yr, L3 passes both gates but is practically absurd (6.5-ton battery, ~30-40+ cows); honest ceiling = demand-min + community
OPEN
The call: The engine sized a 4-person, 2-3kW household on the stewards_ark sovereignty ladder.
What happened: L3 passes both gates but is practically absurd (6.5-ton battery, roughly 30-40+ cows), so the honest ceiling is demand-minimization plus community.
A report sized a 4-person, 2-3kW off-grid household (60kWh/day) at three levels of self-sufficiency: the fully self-sufficient level passes the report's two tests on paper but is practically absurd, needing a 6.5-ton battery and roughly 30-40+ cows for dung fuel (herd sizes were understated before a correction to ~30 kg of collectible dung per cow per day). The honest ceiling is minimizing demand (100W per household) and sharing across a community of about 15 households.
The engine's record — word for word
[Report #157] Verified arithmetic (60kWh/day; 80.75% L1; 86.6% L2; 43.2% L3; 16.5kW PV; 112.5kWh; 150kWh/6.5t; 255m2; 240m3). Faithfully scales the held ~500W L3 worked build to 2-3kW. NET-NEW household_2_3kw_sizing holds the per-rung G1/G2 + half-life table + the verdict (2-3kW L3 is possible but crushing -> industrial ag facility). COW CORRECTION baked: ~30 kg collectible dung/cow/day (not 50), so herds are UNDERSTATED and the 'absurd' verdict hardens (~30-40+ cows for Load A). EXTENDS stewards_ark / l3_output_ceiling / practical_sovereignty_synthesis / dual_gate_sovereignty_test / nife_edison_battery / off_grid_hardening. DISCIPLINE: G1+G2 scored separately; geographic off-grid != sovereignty; L4 held extractability-open, excluded from the build; honest ceiling = demand-min (100W/HH) + community (N=15). NB: the deep-dive lived-reality finding (salvageable core largely theater in practice) is held SEPARATE for the L3-calibration decision. name no holder.
