Adds MonsterStatService. It gives a monster's base HP, MP, close/distance/magic defence, dodge, minimum/maximum damage and hit rate from its race, its level and the levels of its weapon and armour. These are the values before the flat modifiers on the monster entry's HP/MP, WEAPON and ARMOR lines.
Curves
Every defence and attack curve has the form floor((n·level + offset) / d) + perEquipmentLevel·equipmentLevel + upgradeBonus(equipmentLevel) + constant.
The equipment rates are 2 per armour level for defence, 4 for dodge, and 3/5/4 per weapon level for min/max/hit.
The race supplies n/d and the constant.
Ranged attackers: hit rate takes twice the melee level share.
Magic attackers: hit rate is a flat 70.
HP: the pet curve with no growth factor, multiplied by 1.2 from level 37, 1.5 from 52, 1.8 from 62, 2.5 from 72 and 3.5 from 82.
MP: the pet curve with no growth factor.
Critical: base chance 4 % and damage 70 %.
Accuracy against published stats. I checked the curves on 891 monsters of races 0-6 and 8, including entries whose weapon or armour level differs from their own level.
Every stat matches except for two level 30 race 4 entries, which fit no linear curve. The code records that doubt.
MonsterStatDocumentation asserts a few published values and approves the table.
Monster HP, MP, defence, dodge, damage and hit rate per race, level and
equipment level, before the flat modifiers of the monster entry.

This adds monster stat curves without changing existing behaviour. The generated stat table should state that its rows assume equal equipment and monster levels and flag the known race-4 level-30 exception. A test for a monster with a different weapon level would also strengthen coverage. These are small follow-ups, not blockers.

Explanation
The title "Add monster stat curves" matches the main change. The PR adds MonsterStatService, which calculates monster base HP, MP, defences, dodge, damage range, and hit rate from race, level, and equipment levels using curve formulas. The title is short and specific, and it names the core addition without listing files.

Every table row passes level as weaponLevel. The unequal-equipment assertion tests only armour. A regression that substitutes monster level for weapon level in damage or hit-rate calculations could therefore pass this test. Assert recorded damage and hit-rate values for a monster whose weapon level differs from its level. (raw.githubusercontent.com)

Add a recorded assertion in the DocumentationTest case that uses a monster whose weapon level differs from its level, checking both damage and hit rate through MonsterStatService. Keep the existing table rows and unequal-armour assertion, and use expected values recorded for that unequal-weapon case.

Mark the known race-4 exception in the table.
The service records that two published race-4 level-30 entries do not fit its curves. This row presents the calculated values without that limitation, so readers can mistake them for verified values for those entries. Add a note near the row, and generate the note in MonsterStatDocumentation so the approved output stays reproducible. (raw.githubusercontent.com)

State the equipment-level assumption in the table heading.
Every generated row sets weapon and armour levels equal to monster level, but “Monster Stat Table” does not state that condition. A level-41 race-2 monster with level-44 armour has close defence 136; using armour level 41 gives 130. State the assumption in the generated heading and update the approved table so readers do not apply its values to differently equipped monsters. (raw.githubusercontent.com)
