1.0.0

• Synchronize the full Markdown between one source and any number of references, in both directions.
• Implement lazy, display-driven synchronization instead of scanning at startup or after every vault change.
• Persist a structural path/ID/mtime index and content fingerprints rather than complete synchronized block bodies.
• Keep only block-bearing notes in the persisted structural index; discover first blocks through vault events or the explicit full scan.
• Accept consistent outside updates, but refuse to overwrite divergent outside edits, including a single emptied copy found after Obsidian reopens.
• Edit references inline through an embedded Obsidian editor.
• Create embedded Obsidian editors only after a reference is selected.
• Use editor transactions for open notes and keep the vault-wide refresh as an explicit command.
• Support nested source and reference blocks with child-before-parent synchronization, source-to-reference marker projection, parent hashes, and circular-dependency protection.
• Highlight references and provide controls to open their source or remove them.
• Convert a source and all its references back to ordinary Markdown.
• Create sources and references from commands or the editor context menu.
• Pause safely on conflicting edits or malformed markers and open marker errors at their exact line.
• Keep notes portable and readable when the plugin is disabled or outside Obsidian.
• Update documentation, privacy disclosures, and release-guideline compliance.
