Khalim Conn-Kowlessar 61e369faf7 HANDOVER_NEXT: rewrite for strict zero-error cascade pin closure ... Replaces the previous handover. The previous one framed the work as "close three tickets to integer Δ=0" — a weak gate. The user has since made clear the real requirement is **abs=1e-4 on every line ref of every output for every fixture**, and that previous agents have repeatedly made the following mistakes: 1. Treated SAP integer Δ=0 as "closed" (it hides ±0.5 continuous drift). 2. Widened tolerances (rel=0.15 / rel=0.05 / <=0.5) to make tests green — masking real residuals. 3. Tested sections in isolation using PDF values as INPUTS — that verifies the section formula but not the cascade. 4. Diagnosed downstream first when upstream sections still drift. 5. Missed fixture-lodgement defects (bulbs / windows / sap_heating / detailed RR / exposed_floor / door_count / per-window u_value) — the cascade pin failure was the fixture, not the calculator. 6. Labelled code "SAP 10.3" when implementing 10.2. The new handover front-loads these anti-patterns (§A.3), then states the current cascade-pin scoreboard, the work queue in priority order (rooflight, 000487 RR + U=0.86 gable, then §5/§6/§7/§8/§9a/§10a/§11a/ §12 pins in worksheet order), the diagnostic loop, and the spec page anchors the user has already given. Three new memories were also written: - feedback-zero-error-strict (abs=1e-4, no widening) - feedback-cascade-pin-methodology (test the cascade, not isolation) - feedback-fixture-defects-common (audit fixture first) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>		2026-05-23 07:35:25 +00:00
