# Verification checks (P4)

• Clean re-run (results.json deleted, regenerated twice, byte-identical via cmp): PASS
• E1 matches printed % change -35.0 at 1dp: PASS
• E1 recompute: PASS
• E2 recompute 100*1.47/75.0: PASS
• E3 recompute 100*-0.388*0.047: PASS
• E3 magnitude vs abstract '2% employment decline' (same order, negative): PASS
• E4 null with missing_quantity and harmonisable false: PASS
• E5 = 100*-0.0962: PASS
• signs preserved vs baseline printed values: PASS
• n_harmonised + n_not_harmonisable == n_analysed == 5: PASS
• harmonisable items have null missing_quantity: PASS
• n_input_rows matches wc -l: PASS
• feasibility complete consistent (every item has value or justified impossibility): PASS
• exclusions: 5 raw - 0 removed = 5 analysed: PASS
