- Benchmark charset profiles are now length-consistent: all *Short = 40 chars, all *Long = 280 chars, across ASCII, Latin1, CJK BMP, Cyrillic, and Mixed.
- `CharsetSuffixes` was rewritten with new profiles and base-string repetition for compile-time constants.
- Menu/configuration updated for new profiles, selection logic, and improved descriptions.
- Docs updated to reflect new profiles, lengths, and serialization tier impacts.
- `StringSmall` deserialization split into `ReadStringSmallCompact` and `ReadStringSmallFastWire`; all call sites now dispatch by mode, clarifying the hot path.
- SGen codegen and runtime dispatch tables updated for the new decode split.
- Binary marker docs clarified: only Intern/Metadata/Polymorph features are wire-symmetric for reader case omission; RefHandling is not.
- Added `BINARY_STRICT_SGEN.md` planning doc for a SGen-only, attribute-required, AOT-friendly NuGet package.
- Introduce BDN-based runner (AcBinaryVsMemPackBenchmark) mirroring Console's FastestByte scenario; add BdnSummaryAdapter for unified result translation.
- Standardize output: both runners emit .log/.LLM/.output triplets; BDN-native artifacts go under Benchmark/BDN/.
- Simplify CLI: replace granular switches with --serializers; update help and usage.
- Remove legacy benchmark classes; focus on scenario-based approach.
- Rewrite README.md for both AyCode.Benchmark and Console to document dual-runner architecture, output conventions, and dependencies.
- Rotate BINARY_TODO.md; archive closed entries to BINARY_TODO_2026_04.md and BINARY_TODO_2026_05.md.
- Add BINARY_SGEN_OPTIMIZATION.md for SGen per-property emit optimization notes.
- Update comments and docstrings for clarity and maintainability; clarify BenchmarkResult iteration semantics for BDN rows.
