[1.5.1]: 2026-10-18

This patch repairs release documentation packaging after the Windows v1.5.0 archive used checkout-converted line endings. Documents now use exact committed Git bytes, and all four archive changelogs must match the source receipt before signing or publication. The strict npm consumer is unchanged. Documentation-site diagrams also use pinned local renderer assets. This adds no CLI or MCP feature.
