The 12-volt is also "charged"/"maintained" by the DC to DC converter when the car is in READY mode (green car with arrows). If you activate the wipers, the 12 volt bus voltage will jump to about 14 volts and stay elevated for awhile, before dropping back down to its too low maintenance voltage (~12.88 volts, IIRC). You can see this with Leaf Spy. It's been discussed here many times.
Page CH-30 of the '15 manual definitely does not say what you claim. Also, page EV-5 says
CHARGING THE 12-VOLT BATTERY
The 12-volt battery is charged automatically using
electricity stored in the Li-ion battery.
When the 12-volt battery is being charged, the
charge status indicator light on the instrument
panel flashes (except when charging the Li-ion
battery or the power switch is in the READY to
drive position). See “Charge status indicator
lights” in the “Charge” section.
While vehicle is driven
The Li-ion battery charges the 12-volt battery as
necessary when the power switch is in the
READY to drive position or ON position.
While the vehicle is not in use
When the EV (Electric Vehicle) system is off for
an extended time, the 12-volt battery may be
automatically charged for a short period of time
on a regular basis.
In fact, if you leave a car plugged into an EVSE for an extended period of time (e.g. weeks), you will return to a dead 12 volt battery. For some stupid reason, the car is inhibited from doing the above (periodically charging the 12 volt from the li-ion battery) when plugged in. This has been discussed over and over here.
On older manuals, like for the '11, they actually talked about a 5 day interval for light #3 (li-ion battery charging the 12 volt). The li-ion battery doesn't need to be full for this to happen.
While the vehicle is not in use
When the EV (Electric Vehicle) system is off, the
12-volt battery charges automatically for 5
minutes every 5 days.
The charge timing resets to 5 days without
charging the 12-volt battery if:
. The vehicle is placed in the READY to drive
position for more than 5 minutes.
. The Li-ion battery is charged for more than 5
When charging the 12-volt battery, the charge
status indicator light, on the instrument panel
illuminate. See “Charging status indicator lights”
in the “CH. Charging” section.

The 12-volt battery provides power to the vehicle

Yes, it supplies those but so does the DC to DC converter when in READY mode. You claimed

It does NOT run AC NOR HEAT other the fan. The manual doesn't say it does. AC compressor and heater are run off the high voltage bus. The wires from the 12 volt bus would need to be VERY thick to meet the power requirements of the AC compressor and PTC heater.
If you look in the service manual (e.g. HA and HAC sections for HVAC), you will see high voltage warnings over and over in them.
If you look at pics of Leaf AC compressors (e.g. at https://www.ebay.com/itm/11-15-NISSAN-L ... 2067304036
), you'll notice the orange cable and connector, denoting high voltage. You can also see the that at the bottom of https://www.marklines.com/en/report_all/rep1104_201209
for the compressor and PTC heater (that's the one from the '11 and '12 Leaf).
Also reference page FRG-9 of the 2015 Leaf First Responder's Guide at http://www.boronextrication.com/emergen ... rg-hybrid/
. You'll notice that Electric air conditioner compressor and cabin heater have a white number in a black background, denoting high voltage.
Stop misinterpreting or adding words what the owner's manual says.
