Protect periods from ordinary postings during close: Capability Test Specification
Coverage
The table maps each required rule to its specified cases or an explicit finding. Category coverage describes the specification; executable bindings and recorded run results establish different kinds of evidence. Proposed cases remain unqualified.
Interactions With Related Capabilities
Posting protection sits between ordinary ledger work, close-owned financial work and reconciliation. The interaction cases distinguish those entry points. A guard returning an eligible date does not establish that the caller actually writes a ledger entry there.
