## Summary Add `ensureGlobalIdUniqueness` to reassign duplicate node IDs across subgraphs when loading workflows, gated behind an experimental setting. ## Changes - **What**: Shared `LGraphState` between root graph and subgraphs so ID counters are global. Added `ensureGlobalIdUniqueness()` method that detects and remaps colliding node IDs in subgraphs, preserving root graph IDs as canonical and patching link references. Gated behind `Comfy.Graph.DeduplicateSubgraphNodeIds` (experimental, default `false`). - **Dependencies**: None ## Review Focus - Shared state override on `Subgraph` (getter delegates to root, setter is no-op) — verify no existing code sets `subgraph.state` directly. - `Math.max` state merging in `configure()` prevents ID counter regression when loading subgraph definitions. - Feature flag wiring: static property on `LGraph`, synced from settings via `useLitegraphSettings`. ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-8762-feat-deduplicate-subgraph-node-IDs-on-workflow-load-experimental-3036d73d36508184b6cee5876dc4d935) by [Unito](https://www.unito.io) --------- Co-authored-by: Amp <amp@ampcode.com> Co-authored-by: GitHub Action <action@github.com>
