# `Logistiki.Accounting.AccountingTemplate`
[🔗](https://github.com/thanos/logistiki/blob/v0.1.0/lib/logistiki/accounting/accounting_template.ex#L1)

A posting template: an ordered list of posting specs that a policy resolves
into concrete postings.

Each spec references a symbolic account `role`, a `direction` (`:debit` or
`:credit`), and the amount/currency variables (always `:event_amount` and
`:event_currency` in v0.1.0). The journal builder resolves the role to a
concrete account code via the knowledge layer's `account_role` facts.

## Fields

  * `policy` — `atom()` — the policy this template belongs to (e.g.
    `:cash_deposit`)
  * `postings` — `[posting_spec()]` — ordered posting specifications

## Posting spec

Each spec is a map with:

  * `:sequence` — `non_neg_integer()` — ordering within the journal
  * `:direction` — `:debit | :credit`
  * `:role` — `atom()` — symbolic account role (e.g. `:cash_account`)
  * `:amount_var` — `:event_amount` — always `:event_amount` in v0.1.0
  * `:currency_var` — `:event_currency` — always `:event_currency` in v0.1.0

## Example

    %Logistiki.Accounting.AccountingTemplate{
      policy: :cash_deposit,
      postings: [
        %{sequence: 1, direction: :debit, role: :cash_account, amount_var: :event_amount, currency_var: :event_currency},
        %{sequence: 2, direction: :credit, role: :client_liability_account, amount_var: :event_amount, currency_var: :event_currency}
      ]
    }

# `posting_spec`

```elixir
@type posting_spec() :: %{
  sequence: non_neg_integer(),
  direction: :debit | :credit,
  role: atom(),
  amount_var: :event_amount,
  currency_var: :event_currency
}
```

# `t`

```elixir
@type t() :: %Logistiki.Accounting.AccountingTemplate{
  policy: atom(),
  postings: [posting_spec()]
}
```
