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

The result of `Logistiki.process/1`.

Captures the end-to-end outcome of the accounting pipeline for one business
event: the selected policy, the generated journal and postings, the ledger
backend result, projection updates, audit evidence id, warnings, and a human-
readable explanation.

## Fields

  * `event_id` — `term() | nil` — the originating event id
  * `policy` — `atom() | nil` — the selected accounting policy (e.g.
    `:cash_deposit`); `nil` for no-accounting-impact events
  * `template` — `atom() | nil` — the selected template
  * `journal` — `Logistiki.Accounting.Journal.t() | nil` — the posted journal;
    `nil` for no-accounting-impact events
  * `postings` — `[Logistiki.Accounting.Posting.t()]` — the journal's postings
  * `ledger_result` — `Logistiki.Ledger.Result.t() | nil` — the backend result
  * `projection_updates` — `map()` — balance updates keyed by account code
  * `audit_evidence_id` — `term() | nil` — the event id for audit trail lookup
  * `warnings` — `[term()]` — non-fatal warnings
  * `explanation` — `map()` — the full pipeline explanation (policy, template,
    account roles, knowledge explanation, reason)

## Example

    %Logistiki.Accounting.Result{
      event_id: "evt_001",
      policy: :cash_deposit,
      template: :cash_deposit,
      journal: %Logistiki.Accounting.Journal{status: "posted", ...},
      postings: [%Posting{...}, %Posting{...}],
      ledger_result: %Logistiki.Ledger.Result{backend: Logistiki.Ledger.Simulation, status: :ok},
      audit_evidence_id: "evt_001",
      warnings: [],
      explanation: %{policy: :cash_deposit, template: :cash_deposit, account_roles: %{...}}
    }

## No-accounting-impact result

    %Logistiki.Accounting.Result{
      event_id: "evt_007",
      policy: nil,
      journal: nil,
      postings: [],
      explanation: %{reason: :no_accounting_impact}
    }

# `t`

```elixir
@type t() :: %Logistiki.Accounting.Result{
  audit_evidence_id: term() | nil,
  event_id: term() | nil,
  explanation: map(),
  journal: Logistiki.Accounting.Journal.t() | nil,
  ledger_result: term() | nil,
  policy: atom() | nil,
  postings: [Logistiki.Accounting.Posting.t()],
  projection_updates: map(),
  template: atom() | nil,
  warnings: [term()]
}
```
