getDocument

Read a document's content with line numbers. content.text lines are formatted NNNNN<TAB>content (cat -n style); the number+tab prefix is DISPLAY ONLY — never part of the document — so when building editDocument anchor patches, copy only the text AFTER the tab. Reads paginate by lines (offset/limit, default 200): use content.totalLines and content.nextOffset to page. document.versionTimestamp is the optimistic-lock token that every mutating document tool accepts (as versionTimestamp; the older documentVersionTimestamp name also works) — and every mutating tool returns a fresh token, so you rarely need to re-read just to keep editing. Diagrams/images appear as OMITTED markers with metadata (type, diagramId, renderStatus, nlDescription) — use getDiagramInDocument(diagramId) for full DSL code, or pass includeDiagramDsl:true to inline each diagram's DSL and versionTimestamp directly into its DIAGRAM_OMITTED marker (saves a getDiagramInDocument call when you intend to read or edit diagrams).
