Khalim Conn-Kowlessar 3548f1f31a docs(tariff): record Unknown-meter off-peak as a verified non-fix (RdSAP 10 §12 Rules, table_12a)
Khalim's hand-built "simulated case 48" Elmhurst worksheet (main 691 room
heaters + Unknown meter + 903 dual electric immersion + cylinder) proves
Elmhurst resolves an Unknown meter + Rule-3 room-heater main to 10-Hour Off
Peak — Elmhurst SAP 57; ours (STANDARD) 45; routing Unknown+Rule3 to off-peak
(10h) gives 55, 7h gives 45 (so Elmhurst uses 10-hour, RdSAP 10 §12 Rule 3,
PDF p.62). So the prior "Rule 3 is not off-peak evidence" comment was wrong
about Elmhurst's behaviour.

But adopting it REGRESSES the lodged-register corpus 72.5%->71.8% / MAE
0.793->0.827: of 11 Unknown+Rule-3 corpus certs only Apartment 241 improves
(-5.38->-1.05); the other 10 overshoot +2.7..+9.1 (Flat 2 +9.11). The
register's meter_type=3 certs were lodged with STANDARD-tariff costing — the
gov-API "Unknown" is lossy and does not mean off-peak. North star is
reproducing the lodged register, not Elmhurst's deliberate-Unknown worksheet,
so KEEP STANDARD (same "Elmhurst != noisy register" family as
roof-windows/shutters).

Comment-only; no behaviour change (corpus gauge unchanged 72.5% / 0.793).
