## Summary Fix subgraph unpacking creating spurious links to widget inputs (e.g. seed) when the subgraph contains ComfySwitchNode with duplicate internal links. ## Changes - **What**: Two fixes in `_unpackSubgraphImpl`: 1. Strip links from serialized node data **before** `configure()` so `onConnectionsChange` doesn't resolve subgraph-internal link IDs against the parent graph's link map (which may contain unrelated links with colliding numeric IDs). 2. Deduplicate links by `(origin, origin_slot, target, target_slot)` before reconnecting, preventing repeated disconnect/reconnect cycles on widget inputs that cause slot index drift. ## Review Focus - The link-stripping before `configure()` mirrors what `LGraphNode.clone()` already does — nodes should be configured without stale link references when links will be recreated separately. - Deduplication is defensive against malformed subgraph data; the duplicate links in the reproduction workflow likely originated from a prior serialization bug. ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-9046-fix-subgraph-unpacking-creates-extra-link-to-seed-widget-30e6d73d36508125a5fefa1309485516) by [Unito](https://www.unito.io)
