  "message": "Fine. Persist isSimplyBounded; track isValidMixin indirectly.\n\nCapture the simply-boundedness of instance elements in the fine-grained\nmanifest and stop baking `isValidMixin` into item IDs.\n\nWhat:\n- Add `isSimplyBounded` to `InstanceItem` and all subclasses\n  (`ClassItem`, `EnumItem`, `ExtensionItem`, `ExtensionTypeItem`,\n  `MixinItem`). Persist it in summaries and compare it in `match`.\n- Update the summary schema to write/read `isSimplyBounded` immediately\n  after `typeParameters` for all instance items.\n- Reclassify `ClassElementImpl.isValidMixin` from\n  `@trackedIncludedInId` to `@trackedIndirectly`.\n- Bump `AnalysisDriver.DATA_VERSION` from 533 to 536.\n\nWhy:\n- `isSimplyBounded` is an observable property of generic declarations.\n  Not recording it could allow identity reuse when simply-boundedness\n  changes without other shape differences. Persisting it yields more\n  precise matching and invalidation.\n- `isValidMixin` is derived from other fields (e.g., `supertype`,\n  constructors). Tracking it indirectly avoids unnecessary ID churn and\n  reduces over-invalidation while remaining responsive to the inputs it\n  depends on.\n\nImpact:\n- More accurate fine-grained dependency tracking for generics.\n- Fewer spurious item-ID changes from mixin validity checks.\n- Existing caches are invalidated due to the data format bump; no public\n  API changes.\n\nChange-Id: I2700b16add664a4fd127f492fb186c8e1f3635e9\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/448100\nCommit-Queue: Konstantin Shcheglov \u003cscheglov@google.com\u003e\nReviewed-by: Johnni Winther \u003cjohnniwinther@google.com\u003e\nReviewed-by: Paul Berry \u003cpaulberry@google.com\u003e\n",
