  "message": "de: Split explore_page.ts (#4825)\n\nDecomposes the monolithic `explore_page.ts` (~1600 lines) into focused\npure-function\nmodules with explicit dependency injection, improving testability,\nreadability, and\nseparation of concerns. The file is reduced to ~560 lines while\nretaining its\norchestration role.\n\n## Changes\n\n- **`clipboard_operations.ts`** — Extract `copySelectedNodes()` and\n`pasteClipboardNodes()`\nas pure functions operating on minimal state interfaces\n(`CopyableState`, `PastableState`)\n- **`datagrid_node_creation.ts`** — Extract datagrid-triggered node\ncreation (`addFilter`,\n`addColumnFromJoinid`, `parseJoinidColumnField`,\n`findMatchingAddColumnsNode`)\n- **`node_crud_operations.ts`** — Extract node\nadd/delete/duplicate/connect/disconnect\n  operations with a `NodeCrudDeps` interface\n- **`graph_io.ts`** — Extract import/export, JSON loading, template\ninitialization, and\n  explore graph creation with a `GraphIODeps` interface\n- **`node_actions.ts`** — Extract `NodeActions` wiring into\n`createNodeActions()`,\n  `createDeferredNodeActions()`, and `ensureAllNodeActions()`; unify\n`handleInsertModifyColumnsNode`/`handleInsertCounterToIntervalsNode`\ninto a single\n  generic `insertNodeAtPort()` function\n- **`GraphCallbacks` interface** — Group 14 graph callbacks in\n`graph.ts`, passed as a\nsingle `graphCallbacks` field through `BuilderAttrs`, eliminating manual\nforwarding\n- Add comprehensive unit tests for `clipboard_operations`,\n`datagrid_node_creation`,\n  and `node_actions`\n- Update architecture design doc to reflect the new modular structure",
