## Summary - Add `BFloat16` type class with IEEE 754 bfloat16 conversions (round-to-nearest, ties-to-even), matching the JavaScript implementation from #3328 - Add `bfloat16` (type ID 18) and `bfloat16_array` (type ID 54) to the Dart type system, serializers, buffer, codegen, and type resolver - Add 22 tests covering scalar conversions (±0, ±Inf, NaN, subnormals, min/max normal), rounding, equality, buffer round-trips, and packed array serialization ## Changes | File | Change | |------|--------| | `lib/src/types/bfloat16.dart` | New `BFloat16` class with `fromBits`, `fromFloat32`, `toBits`, `toDouble` | | `lib/src/buffer.dart` | `writeBfloat16()` / `readBfloat16()` | | `lib/src/resolver/type_resolver.dart` | `TypeIds.bfloat16=18`, `TypeIds.bfloat16Array=54`, all resolution paths | | `lib/src/serializer/primitive_serializers.dart` | `bfloat16Serializer` constant, write/read cases | | `lib/src/codegen/fory_generator.dart` | All codegen paths for bfloat16/bfloat16_array | | `lib/src/codegen/generated_support.dart` | Cursor `writeBfloat16()` / `readBfloat16()` | | `lib/src/context/write_context.dart` | `writeBfloat16()` method | | `lib/src/context/read_context.dart` | `readBfloat16()` method | | `lib/src/meta/type_meta.dart` | Wire type checks for bfloat16/bfloat16Array | | `lib/fory.dart` | Public export of `bfloat16.dart` | | `test/bfloat16_test.dart` | 22 tests | ## Test plan - [x] All 22 new bfloat16 tests pass (`dart test test/bfloat16_test.dart`) - [x] All existing tests still pass (`dart test`) - [x] `dart analyze` clean (only pre-existing issues) ### AI Assistance Checklist - [x] Substantial AI assistance was used in this PR (yes) - [x] I included the standardized AI Usage Disclosure block below - [x] I can explain and defend all important changes without AI help - [x] I reviewed AI-assisted code changes line by line before submission - [x] I ran adequate human verification and recorded evidence (local/CI checks, pass/fail summary, and review confirmation) - [x] I added/updated tests and specs where required - [x] I validated protocol/performance impacts with evidence when applicable - [x] I verified licensing and provenance compliance AI Usage Disclosure - substantial_ai_assistance: yes - scope: <design drafting | code drafting> Fixes #3287 -- This is an automated message from the Apache Git Service.
