v0.3.2-alpha.1: B-O3 complete and release-candidate hardening (#14)
* Update: gitignore * fix: resolve critical parsing bugs and error type loss (C-1, C-2) - Remove 5 exception-swallowing try/with blocks in Dbc.fs that silently returned defaults on parse failures, risking incorrect C code generation - Add GenerateError DU to preserve error type info through the pipeline (ParseError/ValidationError/CodeGenError no longer flattened to string) - Update Api.fs, Library.fs facade, and CLI to match GenerateError variants - Add Core test project with 13 tests (10 Dbc + 3 Api error propagation) - Fix Windows test compatibility: use mingw32-make and .exe extension - All 29 tests pass (16 Generator + 13 Core), 0 failures * docs: add ROADMAP and session reports for C-1, C-2, Windows compat work * test: add Config, Codegen, and edge case tests (H-1c, H-1d, H-1f) - ConfigTests: 16 tests for Config.validate and Config.loadFromYaml - CodegenTests: 8 tests for Codegen.generate with inline IR - EdgeCaseTests: 4 tests for empty DBC, Motorola LSB, signed, 64-bit signals Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-opencode) Co-authored-by: Sisyphus <clio-agent@sisyphuslabs.ai> * test: add Facade tests and E2E happy-path (H-1e, H-3c) - FacadeTests: 4 tests verifying exception type mapping - ApiTests: 1 E2E happy-path test with examples/sample.dbc - fsproj: add compile items and Signal.CANdy project reference Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-opencode) Co-authored-by: Sisyphus <clio-agent@sisyphuslabs.ai> * docs: update ROADMAP and session report for H-1, H-3 completion - Mark H-1c~H-1g, H-3a~H-3c as complete in ROADMAP - Add session report for 34 new tests (63 total, 0 failures) Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-opencode) Co-authored-by: Sisyphus <clio-agent@sisyphuslabs.ai> * refactor: consolidate Generator into Core via Compat bridge (H-2, M-1) Remove 8 duplicated .fs files from Generator (~1100 lines), replacing them with an 83-line Compat.fs backward-compatibility bridge that re-exports Core types under the Generator namespace. Generator.fsproj now references Core directly and carries zero package dependencies of its own. Key changes: - Generator.fsproj: remove 7 Compile items + 5 PackageReferences, add Core ref - Compat.fs: bridge modules for Ir, Config, Dbc, Codegen, Result (active pattern) - Program.fs: rewritten to use Core API (Config/Dbc/Codegen/Errors) directly - Core Dbc.fs: add missing validateMuxStructure (was in legacy Generator only) All 63 tests pass (47 Core + 16 Generator), E2E roundtrip verified. * chore: remove dead code, improve codegen readability, update deps table (M-2, M-3, M-4) * feat(canfd): remove 8-byte hard limits, add CAN FD support (L-4a, L-4b) - Fix get_bits_le/set_bits_le: replace hardcoded 8-byte loop with dynamic n_bytes - Fix 64-bit mask UB: use UINT64_MAX when length==64 - Fix memset: use message.Length instead of hardcoded 8 - Add 6 F# tests (codegen + edge cases) for CAN FD payloads up to 64 bytes - Add canfd_test.dbc (DLC=64, 3 signals) and E2E test_fd_roundtrip in main.c - Update README: supported features + limitations reflect CAN FD support - get_bits_be/set_bits_be already use dynamic bit-by-bit loops, no change needed * feat(canfd): generate DLC mapping utilities and fix signed signal decode (L-4c) - Add canfd_dlc_to_len() / canfd_len_to_dlc() to generated utils (ISO 11898-1) - Fix signed signal decode: cast uint64_t to int64_t before float conversion to prevent negative values from being interpreted as huge positive numbers * test: add comprehensive CAN parsing tests with known bit patterns - Add comprehensive_test.dbc with 18 signals covering LE/BE, signed, packed, non-aligned, and scale/offset configurations - Add 7 C E2E test functions verifying byte-level encode/decode correctness - Add 5 F# unit tests for DLC mapping codegen and signal pattern generation * docs: update ROADMAP L-4c complete and add session report * docs: clean up renamed report files and add 260213 morning briefing * chore: track AGENTS.md, Report/, and ROADMAP.md publicly * docs: add git workflow setup session report * ci: add

- Branch selection uses the raw integer value of the switch signal (typical DBC semantics).
327327
- Base (non-multiplexed) signals are always decoded/encoded.
328-
- Valid bitmask width: current implementations use a 32-bit `valid` field. Extremely large messages with >32 branch/base signals may require widening (e.g., to 64-bit) or an array. This is called out in Limitations; auto-widening is on the roadmap.

- Valid bitmask width: messages with โ‰ค32 signals use a 32-bit `valid` field (`uint32_t`); messages with 33โ€“64 signals automatically use a 64-bit field (`uint64_t` + `1ULL` shift). Messages with >64 signals cannot be generated โ€” codegen reports `CodeGenError.UnsupportedFeature`.
