Aluminum edging (6061-T6 stock, 2.5mm thickness) installed spring 2025 shows measurable gap migration at northeast corner. Initial fit: flush. Current offset: 2.3mm. Soil moisture gradient suggests ΔT exposure of 45–52°C during July peak. Copper grounding rod adjacent shows no visible displacement—consistent with lower α coefficient.

Steel mesh (galvanized, 50mm hex) exhibits tension variance between noon and midnight readings. Noon deflection at mid-span: 47mm. Midnight: 31mm. Differential: 16mm. Gate hinge play increases 0.8mm per °C above ambient baseline. Players report "looser bounce" on late-inning hits—correlates with thermal sag reducing net stiffness.

Expansion joint at oven interface migrated 0.4mm outward over 18 months. Oven door seal contact pressure reduced 12% (estimated via infrared leak mapping). Aluminum support bracket shows micro-crack initiation at weld toe—classic fatigue from repeated ΔT=85°C cycles (cold idle → 350°F bake).
