Open questions

• These are Ontario accounting lives from municipal capital asset policies, not planning or observed replacement data.
• A municipal minimum standard tied to the statutory defence in s.44 of the Municipal Act, 2001; patrolling is a drive-by observation of the whole road, not a component-level inspection. Not an official version.
