  "message": "Deduplicate MergedConfiguredTarget instances across dependency edges.\n\n`AbstractConfiguredTarget` overrides `hashCode()` based on target label and configuration key so that `ConfiguredTarget` instances placed in Starlark dicts have deterministic hash codes, while leaving `equals()` as reference equality (`Object.equals`). Because `MergedConfiguredTarget` is created freshly for every incoming dependency edge during aspect propagation, placing aspect-decorated dependencies into a Starlark `depset` or `dict` fails to deduplicate across edges and causes all incoming edges for the same target to collide in the same hash bucket during `depset.to_list()`.\n\nOverriding `equals()` on `MergedConfiguredTarget` to compare the underlying base target and attached aspects (while retaining `AbstractConfiguredTarget`\u0027s deterministic `hashCode()`) allows Starlark `depset`s and `dict`s to deduplicate aspect-decorated targets across edges in O(1) time without regressing hash determinism.\n\nRELNOTES: None.\nPiperOrigin-RevId: 1009072109\nChange-Id: Ied88e64c4a508fe1b53cff851acec4c6280d3019\n",
