From 61c007e5dec7ce4c660c55267237bc3aaaf7da9a Mon Sep 17 00:00:00 2001 From: Khalim Conn-Kowlessar Date: Sat, 30 May 2026 20:13:35 +0000 Subject: [PATCH] =?UTF-8?q?Slice=20S0380.115:=20fixture=20pin=20ECF=205.38?= =?UTF-8?q?66=20=E2=86=92=205.3868=20per=20worksheet=20(PDF=20line=20593)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The cert 000565 ECF pin was a transcription typo. U985-0001-000565.pdf line 593 (Block 1, 11a SAP rating individual heating systems) reads: Energy cost factor (ECF) [(255) x (256)] / [(4) + 45.0] = 5.3868 (257) The pin captured 5.3866 — likely a mis-copy from line 871 / 873 (Nov MIT (92)m = 15.3866). The cascade output 5.386823 matches the worksheet PDF at 4 d.p.; the pin was always 0.0002 wrong against the source. Per [[feedback-verify-handover-claims]], handover narratives are verified against the source PDF; the cascade is correct and the pin was wrong. Test movement: `test_sap_result_pin[000565-ecf]` now passes (diff 0.000023 against the corrected pin 5.3868, within abs=1e-4). Four expected fails remain (cost / CO2 / SH / main_fuel) — closed in the next slice (A_RR_shell rounding per RdSAP 10 §15).
