# Settled Reach — Production Chain Recipes
# Source of truth. Compiled to systems.db via `make economy-db`.
#
# Leontief fixed-coefficient recipes (D-173, D-178).
# Multiple chains MAY produce the same output (structural substitution).
# Services have NO production chains — they are demand sinks.
# Brands are NOT in this system — brand corporations are commodity buyers.
#
# Fields:
#   output            commodity_id of the product
#   output_quantity   units produced per cycle (float, default 1.0)
#   inputs            array of { commodity, quantity } pairs
#   location_bound    chain requires specific local resources (default false)
#   description       human-readable recipe description (optional)
#
# Decisions: D-173 (taxonomy), D-178 (Leontief), D-182 (TOML pipeline)
