# Crafting: goods and embedded recipes (ORIGINAL content)

The SRD prices finished arms but has NO material recipes — its downtime
crafting is gp-rates only. Everything in this section is therefore OURS
(the `alignment_bias` precedent: original additions living inside or
beside `.srd.ron` files, explicitly marked): the `goods/` collection,
every `recipes:` list, and all quantities, tiers, and hours.

- **The goods collection** (`goods/<id>.ron`, `source: Original`, one
 file per material): a starter set of 12 sufficient to give every SRD
 weapon and armor a plausible recipe — iron_ore, coal, iron_ingot,
 timber, hide, leather, cotton, cloth, sinew, and the four artisan's
 tools. Raw naturals (ore, coal, timber, hide, sinew, cotton) have
 no recipes — they are gathered or traded; intermediates (iron_ingot
 from ore+coal at the smithy, leather from hide at the tannery, cloth
 woven from cotton at the loom) carry
 theirs. The tools' WEIGHTS are aligned with the SRD equipment table's
 artisan's-tools rows (noted per file); their VALUES, and every other
 good's, now DERIVE (/0396): worth = material cost ÷ `yield` +
 `labour_rate(tier)` ÷ `rate`, and no file states a price. **Weapons and
 armour are the same rule since §5**: the book's price column is
 no longer transcribed at all. It never reached a price — only a
 materials-≤-price sanity bound, which the derivation makes
 unrepresentable (labour is non-negative, so `worth ≥ materials` holds by
 construction on any `yield: 1` row) — and while it sat in the file it was
 a second, quieter authority over the same quantity. What the SRD's plate
 price actually recorded, a brand/scarcity premium some 300× the raw
 craft cost, belongs to the market layer, and the market layer is where
 it now lives. The `bedroll`
 is the first TERMINAL consumer good — a carpentry product
 off the timber and cloth chains, `quality_class: "good"` marking it a
 fitted item (used, not crafted onward), so the orphan check reads it as
 a legitimate sink; its weight aligns with the SRD's bedroll row and its
 value derives like every crafted good's.
- **Recipes are EMBEDDED in item definitions** — `recipes:` on Weapon,
 Armor, and Good. **Craftable is DERIVED from having recipes, never a
 flag.** `Recipe.station` ids resolve at boot against the union of the
 building types' `stations` lists (today: smithy, tannery, carpentry,
 weaver, ovens, mash_house); `tier` is the ladder; `tool`
 references a good id (`None` = bare hands — a club is whittled).
 Constructive inputs are CLASS-GENERIC (`Class("metal")` — any
 material of the class satisfies; a mithral dagger needs no dagger
 variant); process inputs stay specific ids (`Good("coal")` — iron
 ingots come from iron ore, not "any metal").
- **The strike table (the rare find in the bulk):** an
 EXTRACTION recipe (one with no `inputs`) may carry
 `strike: Some(Strike(good: "<id>", odds: <0..1>))`. Each unit the face
 earns then rolls a SECOND die for its IDENTITY: the rare good at `odds`,
 the bulk good otherwise. It splits identity, NEVER quantity — bulk +
 rare equals exactly what the face would have minted without it, so a
 strike never mints or loses a unit. The mountain mine's `iron_ore` row
 strikes `mithral_ore` at 0.08; its `stone` row strikes `iron_ore` at
 0.15. An unknown good or a non-probability `odds` fails boot.
- **Richer ground, richer vein ( §5):** a `Strike` may carry
 `mods: [(tag, multiplier)]` — the `terrain_mods` rule applied to the
 odds. The effective chance at a venue is `odds × Π(multiplier for each
 town terrain tag present)`, clamped to a probability. One row can
 therefore run a fat seam in one town and a thin one in the next without
 a second recipe or a hand-wired deposit: the ground decides. Tags
 resolve against `tables/terrain_tags.ron`; a negative or non-finite
 multiplier fails boot.
- **Boot feeds these into the EXISTING production machinery**:
 recipes become graph structure, worldgen assigns the venues, and
 there is NO parallel crafting system. The make-check quality rule
 generalizes here later (tier + check → quality); material `weight_lb`
 feeds the arbitrage cart loads.
- **Batch yield (the ammo fix, landed):** a `Recipe` carries a
 `yield` (units one run makes) and the derivation divides by it, so
 ammo-scale goods price sanely instead of costing more per unit than the
 ingot their head is cut from — the ledgered fix, not a price fudge. The
 first batch goods are `arrow` and `bolt` (20 to a fletcher's run at
 carpentry: 27 cp material + 3 h labour ÷ 20 = 1 cp/unit). They are the
 honest ledgered SEAM — craftable and grounded, but nothing CONSUMES them
 yet (the orphan warning stands until combat spends ammunition in a later
 slice). Every prior recipe is `yield: 1`, explicit (no serde default).
