- Replace single String marker with StringLen8/16/32 (167–169) for explicit string length encoding (1/2/4 bytes)
- Update serialization/deserialization logic and marker checks for new scheme
- Rename charset suffixes: Latin1FixAscii → AsciiFix, add Latin1Fix (5-char Hungarian)
- Update menu, argument parsing, and references for new charset/test names and order
- Swap MaxDepthBehavior enum values: Throw=0, Truncate=1
- Update comments and docs for new marker and charset conventions
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.
Major refactor: all benchmark engine implementations, enums, and helpers moved from Console project to AyCode.Core.Benchmarks.Workloads.Scenarios for unified cross-runner use. BenchmarkResult and reporting logic moved to AyCode.Core.Benchmarks.Reporting. Attribute-flag aggregation centralized in BenchmarkOptions. Updated all usages, project references, and SGen codegen for ref-handling. Prepares codebase for shared reporting and future extensibility.
Refactor benchmarks to use typed enums for engine/mode
Replaced string-based identifiers for serializer engine, I/O mode, and dispatch mode with strongly-typed enums (BenchmarkEngine, BenchmarkIoMode, BenchmarkDispatchMode). Added BenchmarkEnums.cs with ToDisplay() helpers for consistent output. Updated all benchmark implementations, DTOs, and output logic to use enums. Removed obsolete string constants from Configuration.cs. Merged allocation measurement methods in BenchmarkLoop.cs for clarity. Improves type safety, maintainability, and output consistency.
Refactor: split Program.cs into Menu, Output, DTO
Refactored the benchmark console app for modularity:
- Moved all menu logic to Menu.cs (main/settings menus)
- Moved all output/result formatting to Output.cs
- Extracted BenchmarkResult DTO to BenchmarkResult.cs
- Program.cs now only handles orchestration and the benchmark loop
- Moved GetCurrentCharsetName to Configuration.cs
- Removed obsolete Warmup methods from serializers
No functional changes; improves clarity and maintainability.
Refactor: centralize config/state in Configuration.cs
Moved all benchmark configuration, mutable state, and attribute-flag aggregation from Program.cs to a new Configuration.cs static class. Updated all references in Program.cs and related benchmark classes to use Configuration.<value>. Removed the "profiler" CLI mode and its code. Updated README.md to reflect these changes. This improves maintainability and keeps Program.cs focused on orchestration and UX, with no changes to benchmark logic.
