Closes the residual S0380.177 exposed on oil 6. The cascade's central
heating pump used the bare Table 4f age default (41 kWh for "2013 or
later") but the worksheet (230c) = 53.3 kWh.
SAP 10.2 Table 4f (PDF p.175) footnote a) on the "Circulation pump"
rows reads verbatim: "Multiply by a factor of 1.3 if room thermostat
is absent." oil 6 lodges control code 2101 ("No time or thermostatic
control of room temperature") = no room thermostat, so 41 x 1.3 = 53.3
= ws (230c) EXACTLY; pumps/fans (231) = 53.3 + 100 (liquid-fuel boiler
flue fan/pump) = 153.3 EXACT. Same root cause (absent room thermostat)
as the S0380.177 Table 4c(2) interlock fix — both keyed on the new
`_BOILER_NO_ROOM_THERMOSTAT_CONTROL_CODES = {2101, 2102}`.
`_table_4f_circulation_pump_kwh` now multiplies the resolved pump kWh
by `_TABLE_4F_NO_ROOM_THERMOSTAT_PUMP_MULTIPLIER = 1.3` when the main's
control code is in that set.
oil 6 now FULLY EXACT on all four metrics (ΔSAP/cost/CO2/PE < 1e-4).
The sibling oil 5 (same "2013 or later" pump age but control 2106 WITH
a room thermostat) keeps the bare 41 kWh and is unaffected — as do the
other 39 corpus variants (2101/2102 appear only on oil 6). 935 pass;
pyright net-zero 32 -> 32.
