  "message": "feat: add `backward.isDefEq.implicitBump` option\n\nThis PR adds the `backward.isDefEq.implicitBump` option (default: `false`)\nthat controls whether all implicit arguments get their transparency bumped\nto `TransparencyMode.instances` during `isDefEq`, not just instance-implicit\nones. When enabled, `[implicit_reducible]` definitions like `Nat.add` and\n`Array.size` are unfolded when checking implicit arguments, closing the gap\nbetween instance-implicit and regular implicit argument handling.\n\nThe default is `false` for staging purposes. After stage0 is updated, the\ndefault will be flipped to `true`.\n\nCo-Authored-By: Claude Opus 4.6 \u003cnoreply@anthropic.com\u003e\n",
