Rules and numbers

confirmed Success XP = floor(baseXP x 2^(tier/2)), so each tier is worth about 1.414x the last.successXP = floor(baseXP * 2^(tier/2))
Source: Constants.js:75-78
confirmed Fail XP = max(1, floor(successXP x 0.1)).failXP = max(1, floor(successXP * 0.1))
Source: Constants.js:80-83
confirmed All XP bonuses add into one fraction applied once: tools, capes/pets, Alms&Luck perks, medallions, compasses, telescopes, Fortress milestones, beacons, Collector, talents.xp = round(actionXP * (1 + sum(bonuses)))
Source: ClientState.js:2625-2711
confirmed Tooltips apply the bonus to both success and fail XP.
Source: SkillCustomModal.js:2246-2249
inferred Lucky tasks pay 2x XP (LUCK_TASK_XP_MULT); we assume it multiplies the bonus-applied XP, which the server decides.
Source: Constants.js:179
confirmed Processing scraps or scrap coins pays half XP (SCRAP_XP_DIVISOR 2).
Source: Constants.js:412
dev note A patch note says every XP boost is capped at +75% per skill; no such cap is in the readable code.
Source: LoginScreen.js:302 (patch note)
confirmed Most skills cap at 99 (50M XP); slay, delve, fortify, luck and alms go to 120 (400M XP); the hard cap is 500M XP.
