Adds --export-wcra-json / --import-wcra-json. Variable-length
reagent arrays serialize as JSON object array of {itemId, count}
allowing hand-edits of recipe formulas. tradeSkillName field on
export is informational (tradeSkillId int is authoritative).
All 3 presets (alchemy/engineering/blacksmithing) byte-identical
binary roundtrip OK including the 5-reagent Target Dummy
recipe.
Live-tested perpetual-motion validator: hand-mutated Minor
Healing Potion (recipeId 1, produces itemId 118) to add itemId
118 to its reagents. Validator correctly errored: "reagent
itemId equals producedItemId=118 — recipe consumes what it
makes (perpetual-motion bug)" — catches a class of crafting
bugs that would silently let players duplicate items.
CLI flag count 1398 -> 1400.
Novel replacement for the implicit recipe expansion vanilla WoW
carried in SpellReagents.dbc + Spell.dbc effect-24 (CREATE_ITEM)
+ per-trade-skill SkillLineAbility rows. Each WCRA entry binds
one trade-skill recipe spell to its variable-length reagent
list (itemId+count pairs, vanilla cap 8, format cap 32),
produced-item id + count, the trade skill it belongs to, the
minimum skill level to cast, and the source item that teaches
the recipe.
Three presets seeded with canonical vanilla item/spell IDs:
--gen-cra-alchemy 4 potions (Minor/Lesser Healing+Mana,
Greater Healing, Major Mana) using
herb itemIds 2447/765/2450/3357/etc
and Empty Vial / Crystal Vial
--gen-cra-engineering 3 recipes including Target Dummy with
5 reagents (variable reagent count
demonstration); learnedFromItemId
references the recipe blueprint
--gen-cra-blacksmithing 3 recipes covering low/mid/high tiers
(skill 1 / 50 / 235) including Heavy
Mithril Helm with 4 different bar/ore
reagents
Validator catches: id+name+spellId+tradeSkillId+producedItemId+
producedCount required, no duplicate recipeIds, no duplicate
spellIds (cast-handler conflict — two recipes responding to the
same cast), no zero-itemId/zero-count reagents, no duplicate
reagent itemIds within a single recipe (should be merged into
single entry with summed count), no self-reagent (recipe
consuming its own produced item is a perpetual-motion bug).
Warns on requiredSkillLevel > 450 (above WotLK cap) and empty
reagent list (free-to-craft is unusual but allowed for some
alchemy transmutes).
Format count 132 -> 133. CLI flag count 1391 -> 1398.
