Data points: no pre-flight extra fuel
This may not be quite right, because the report says on P. 19:
"The on-board fuel weight corresponded to forecast trip fuel of 63,900 kg,
route factor fuel of 1,460 kg,
final reserve of 2,200 kg,
fuel to alternate airport reserve of 1,900 kg and
940 kg additional fuel.
An LMC (last minute change) corrected the definitive load sheet to take into account one passenger fewer without baggage.
"

So, it had 940 kg additional fuel.

Also, the report says on p. 18:
"The estimated takeoff weight was 232,757 kg (11),
for a maximum authorised takeoff weight of 233 t."

So, the a/c was 243 kg under MTOW on take-off, about 0.4% of the total fuel load, with not much of an option to take on more fuel.

The report also says it left the gate over MTOW.

Without the LMC, the TO weight would have been even nearer the MTOW, 91 kg nearer if the missing passenger was a man, 72 kg nearer if a woman.

Looking at the fuel planning, it looks as though the Captain thought it was likely that he might have to deviate for weather.
