Background

backgrounds/<id>.ron — an origin: the GRANT half of the grant/use split. A soul's background is where its skill proficiencies come from; the trade it works is its [Profession], which USES those skills at the bench, never grants them. The SRD ships one background (Acolyte); the rest are OURS, the profession precedent.

A D&D origin is a BUNDLE, not a skill pair: beyond skills it may nudge ability scores, carry a named feature, and outfit the soul with starting coins and equipment. All four extras default empty, so thin origins and any mod file parse unchanged. Tools stay OFF the origin — trade competence is a trained tier the profession owns.

Field	Type	Required	Description
abilities	[Ability, int8][]	default []	Ability-score bumps this origin grants — `(ability, +bonus)` pairs, the `RaceDef::asi` idiom, composed on top of the racial ASI the way every other increase composes.
coins	uint32	default 0	Starting coin the origin outfits the soul with — minted to its purse at genesis (`Time::ZERO`).
equipment	EquipmentGrant[]	optional	Starting goods the origin outfits the soul with — minted as stacks it carries at genesis.
feature	BackgroundFeature	optional	The origin's feature — the "more than a stat" half of a D&D background (Shelter of the Faithful, Criminal Contact). DERIVED onto a soul from its carried background id, never stored twice.
id	string	required	Authored id.
name	string	required	Authored name.
skills	Skill[]	required	The skill proficiencies this origin grants (an SRD background grants two); unioned onto the soul's set at generation (`soul::finalize`).
source	Source	required	Authored source.

Nested shapes

Every shape Background closes over, so this page stands alone.

Ability

An open, validated Ability id interned from authored data.

BackgroundFeature

A named origin feature: the half of a D&D background that is not a number. Every feature carries a validated mechanical provision row. text is the flavor the creator sheet shows and the chronicle can quote.

Field	Type	Required	Description
name	string	required	The feature's short title (Never Lost, Never Hungry).
provisions	Provision[]	required	Goods this origin can provide while travelling. The validator requires at least one row and resolves every good against `data/goods/`.
text	string	required	The feature's prose — what standing or knack the origin confers, shown on the creator sheet and quotable in the chronicle.

EquipmentGrant

One starting-goods grant an origin outfits the soul with: qty stacks of the good (a data/goods/ id), minted at genesis.

Field	Type	Required	Description
good	string	required	The good granted — a `data/goods/` id, resolved to a concept at placement.
qty	uint32	required	How many of the good to mint into the soul's hand.

Provision

One generic travel provision supplied by a composed feature.

Field	Type	Required	Description
good	string	required	A `data/goods/` id supplied on the road.
units_per_day	uint32	required	Units supplied per travel day.

Skill

An open, validated Skill id interned from authored data.

Source

Every file's top-level value carries source.

`Srd51`

SRD 5.1 — retained nonconflicting catalogue material.

`Srd52`

SRD 5.2.1 — the 2024-revision System Reference Document, the same CC-BY-4.0 grant as 5.1 and the current rules chassis. Its files carry the .srd52.ron suffix so provenance reads off the path; see data/README.md for which document rules a given value.
