Move [Unreleased] to [1.0.0] - 2026-07-09 in Keep a Changelog form —
for an initial release everything folds into Added, describing the
shipped surface (lossless capture, DAG compaction, retrieval and
synthesis, offload, map, integrations, operations) — and add the
comparison-style link references. The narrative release notes live at
docs/release-notes/RELEASE_NOTES_1.0.0.md, matching the sibling repos'
convention, and the changelog entry links to them.
