Overview

Builds a CsvSchema from a user-provided YAML configuration hash.

Supported direction strategies:

positive_debit   — positive amounts are outgoing (e.g. AmEx)
negative_debit   — negative amounts are outgoing (e.g. generic bank export)
indicator_column — a separate column holds "Debit"/"Credit" labels

%w[required_headers amount_key direction date_column date_format payee_column].freeze
DIRECTION_STRATEGIES =

Simple direction lambdas: amount sign alone determines debit/credit. indicator_column is handled separately since it needs config context.

{
  'positive_debit' => ->(_row, amount) { amount.positive? ? :debit : :credit },
  'negative_debit' => ->(_row, amount) { amount.negative? ? :debit : :credit }
}.freeze
