- Refactored AcBinaryDeserializer string marker dispatch: hot path now handles all non-interning markers in a single inlinable method, cold path only for interning markers; improved safety and comments.
- Updated SGen codegen to only emit cold-path for interning-enabled types.
- Added debug guard for corrupted wire in ReadStringBig.
- Rewrote JitDisassemblyBenchmark as a direct JIT-disasm harness (outside BDN); updated Program.cs to use it for --jitasm.
- Benchmarks now pin charset to Latin1Short for cross-process consistency.
- Added new Bash commands for diff, JIT disasm, and diagnostics in settings.local.json.
Introduced a new "SGenOnly" build configuration across the solution, updating Directory.Build.props, AyCode.Core.targets, and the .sln file for full support. Centralized TargetFramework and build properties in AyCode.Core.targets, removing redundancy from project files. Updated code to recognize SGEN_ONLY at compile time. Added new Bash commands for file conversion and cleanup. No functional code changes outside build and configuration logic.
- 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.
