Armor

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_cp) 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.

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.
