Envelope U-value film convention: OSut path (with films, code-literal) vs BTAP path (construction-only) disagree by ~4% on the same Table 3.2.2.2 values

NECB reference modeling rules: sys4 control-zone cooling ΔT overwritten with heating value; 5.2.2.7 economizer trigger defects; Table 8.4.4.14 pump curves, 8.4.4.6 purchased energy, and a dead DCV guard

NECB Table 8.4.4.7.-A selection: residential row still 2011-text (no identical-to-proposed / through-the-wall branches); unlisted space types hard-raise instead of the 8.4.4.7.(3) fallback

NECB VAV reference fans: Table 8.4.4.17 curves + minimum-flow column conflated (2011 cubics, E-for-D), 8.4.4.18 combined efficiencies replaced by motor tables — measured ~2.2x fan energy on LargeOffice

NECB2020 infiltration default: envelope area S includes attic roofs; A_AGW counts all Outdoors surfaces instead of above-ground walls (3.2.4.2.(1)(c) / 8.4.2.9.(2))

PRM baseline space_type_light_sch_change and model_apply_standard_infiltration are nondeterministic (undefined iteration order + cache-key mismatch + stacked suffix)
