ClassDef

The six ability scores (SRD 5.1). The engine's own stats::Ability is the runtime type; this is the data-layer mirror, bridged by [Ability::engine].

The SRD armor categories — light/medium/heavy body armor and the shield.

A feature granted at a class level: id resolves against the engine's implemented feature registry (classes::Feature) at boot — OR defines itself as a pure PASSIVE: an open id carrying its own name and modifiers (a mod's fighting style is a data row). The validator enforces the fork: a registry id may not re-name itself; an open id must self-define and can never spend uses (spend mechanics are engine code).

Where a passive modifier lands — the closed hook set: one variant per NUMBER the engine already reads. A hook without a consumer stays out (ledger-don't-fake): attack/damage hooks arrive with the kit's weapon-identity read so the skirmish and the bubble apply them alike; save/check/heal hooks with theirs.

When a modifier applies.

One passive adjustment: amount onto hook while when holds — the data half of a feature's mechanics. Registry features may carry their mechanics here (Defense, Improved Critical do); an OPEN-id grant (a mod's own passive) must.

The SRD Multiclassing ability prerequisite (SRD "Multiclassing"): the minimum ability score(s) a soul must MEET to add — or keep — this class in a multiclass. all entries are ALL required (Monk's Dex 13 AND Wis 13); any_of, if non-empty, needs at least ONE (Fighter's Str 13 OR Dex 13). assign_class gates on it (classes::multiclass_prereq_refusal). Absent = no prerequisite (a single-class assign never consults it). A single-class soul is unaffected: prereqs bite only when a SECOND class is added.

The REDUCED proficiencies a class grants when taken as a MULTICLASS (SRD "Multiclassing" proficiencies table) — a subset of the initial-class set, with NO saving-throw proficiencies (SRD). armor is the reduced armor training (unioned into classes::trained_armor for the casting gate); skills is how many of the class's own skills.from the multiclass-in grants (the deterministic front pick — 0 for the classes that grant none). The reduced WEAPON set and tool/instrument grants are SRD too but have no runtime gate yet (ledgered, never faked). Absent = nothing granted on multiclass-in.

The eighteen SRD skills.

A class's skill training: pick count from from — the list membership is the SRD's; its ORDER is our quick-build priority, which the deterministic auto-pick takes from the front (player choice is ledgered).

Slot progression — which slot grid a caster derives capacity from. Full reads tables/spell_slots.srd.ron (cleric/wizard); Half reads tables/spell_slots_half.srd.ron (paladin/ranger — no slots at 1st, up to 5th-level slots by 17th); Pact reads tables/pact_magic.srd.ron (the warlock — a small number of slots, ALL at one rising slot level, that recharge on a SHORT rest).

Every file's top-level value carries source.

A class's spellcasting block. Prepared-count = ability mod + class level (min 1) DERIVES (the SRD's own rule for cleric/wizard) — never stored.

The class's SRD starting kit — the class page's "Equipment" block at its (a) options, as arms-table ids. What a classed-but-unarmed soul BORROWS (combat::loadout — the class dresses its own, ahead of the org-archetype block): the rogue watchman walks in leather with a rapier, not the guard block's chain shirt and spear. The wizard's armor list is empty — robes are no armor at all.

The class's SRD subclass (each SRD 5.1 class prints exactly one), applied automatically at level — the subrace precedent: carried inside the class file, no selection substrate until a second subclass exists to choose.

Weapon training: the category flags plus any named ids (the rogue's hand-crossbow/longsword/rapier/shortsword list).
