Good

How a bulky piece stands in its room; a closed set.

The picture the board draws for this piece: a path inside an art/ directory, e.g. "furniture/trestle-table.webp". Drawn facing north, width_cells across and length_cells down, with the back edge at the top; the board rotates it for the other facings. A mod's art/ is searched before data/art/, so shipping the same path replaces the base picture. A path that resolves nowhere fails the load.

The piece's mechanical rectangle. Orientation is chosen cardinally when the deterministic board dressing places the individual piece.

Room ROLES this piece dresses, validated against building programs. Empty = a trinket that casts no shadow.

Does the piece LIGHT its room? The lamp does; the mug does not.

Length from the furnishing's front to its back.

Width across the furnishing's front.

A tables/material_classes.ron id (metal/wood/leather/cloth), boot-resolved.

Object-hp multiplier (mithral 4.0).

The CraftTier floor to work it at all (mithral: Expert).

Lifts the craft check that ROLLS the tier (mithral +4): better stock, better odds.

Worldgen rarity hint for the material.

Durability/strength as prose; a later engine consumer reads it.

Bonus over the class hardness (mithral +3).

Value multiplier on constructed items (mithral 10.0).

Weight vs the class baseline (mithral 0.5).

Extra labour, pairs with min_tier gating (mithral +5); never touches the quality roll.

The ability whose mod feeds output; absent = untrained extraction.

The building TYPE that produces this good (a data/buildings/ id, boot-resolved): a recipe names its building directly, and the build-time derivation mints one Produces edge at every venue of that type. Producing vs merely crafting is NOT authored: every recipe is a candidate Produces edge and the opportunity-cost engine (best_row) decides what a shift makes. The only recipes that do not derive an edge are those the 2-input edge model cannot hold (3+ distinct inputs) — a substrate limit, ledgered, not a producibility flag.

The exclusion half of the terrain GATE (see requires_terrain): the recipe is skipped at any venue whose town bears one of these tags.

Labour hours one batch takes.

The (input, qty) pairs consumed per batch — boot-resolved. EMPTY = raw extraction (nature's own yield): such a recipe names WHERE and HOW FAST a raw is won, carries no CRAFTED flag, and keeps the extraction lottery. A recipe WITH inputs is a craft (sets CRAFTED).

Units per worked hour, before the work multiplier. The recipe carries it, so production truth lives in one place.

Terrain GATE: this recipe is wired only at venues whose town bears every requires_terrain tag and NONE of forbids_terrain. Lets a good be made two ways by place — coast/vale bread bakes flour where an arable mill stands; the mountain bakes grain direct where it does not. Empty gates = wire wherever the building stands.

The face's RARE find: each produced unit has odds chance of striking this good instead of the bulk yield — the mithral vein in the stone. Absent on ordinary recipes.

Terrain-tag rate MODIFIERS: the effective production rate at a venue is rate × Π(multiplier for each town terrain tag present). Regional divergence emerges from the GROUND, not hand-wired per venue — grain grows richer on arable, an ore seam runs faster in mountains. Empty = the base rate stands everywhere the recipe is wired.

The tool-proficiency floor to run this recipe.

A goods/ id (e.g. "smiths_tools"); absent = bare hands.

Units the batch yields: one run of inputs + hours makes this many of the good — the ammunition fix the pricing ledger named (arrows come 20 to a batch, so their per-unit worth is sane). The derivation (recipe_worth_minor) divides material + labour by it, so a per-unit anchor round-trips. Explicit in EVERY recipe — the RON key is yield; the no-serde-default contract's one exception is quality_overrides, and this is not it (1 for a single-unit craft).

The rare good struck — a goods/ id, boot-resolved.

Terrain-tag odds MODIFIERS, the terrain_mods rule applied to the strike: the effective chance at a venue is odds × Π(multiplier for each town terrain tag present), clamped to a probability. A richer vein is GROUND, not a hand-wired deposit — the same seam runs fatter where the rock says so. Empty = odds stands everywhere the recipe is wired.

Per-unit chance (0..1) of striking good instead of the bulk yield.

AC delta at this tier (armor); absent = n/a.

Attack-roll delta at this tier (weapons); absent = n/a.

Damage delta at this tier (weapons); absent = n/a.

Lock DC delta vs the Normal DC 10 base at this tier (locks); absent = n/a.

Max-integrity multiplier (the structure class) — defaulted so the arms/tool/lock profiles never spell it.

The quality tier this row describes.

Worth multiplier at this tier (every class).

Work-output multiplier at this tier (tools); absent = n/a.
