Posting Freezes Accounts Resolved From Current Configuration

Context

The accepted architecture moves financial account selection from document issue to posting. This record carries that decision forward without reopening it.

Decision

Posting reads the current product setup and unit defaults and freezes the resolved accounts, leaving posted values unchanged by later configuration edits.

Alternatives Considered

Freeze account assignments when a document is issued. The posting-time ruling supersedes this and permits incomplete setup before posting.

Consequences

Posting owns preservation and its proof. The console's regenerated share keys create a separate reconciliation concern across edits.
