Defence file
A structured evidence workspace that keeps prevention-procedure evidence, owners, dates, review decisions, and source lineage together for human and adviser review.
Source baseline: 2026-06-15
Plain-language use
It is an operating record for how evidence was collected and reviewed, not a legal conclusion.
Safe use: Use for workflow and audit-readiness language; do not say the file creates a statutory defence.
