## Summary
Add LSP trace recording and replay-based smoke testing infrastructure.
### clice changes (`src/clice.cc`)
- Add `--log-level` CLI option with validation (rejects unknown levels
instead of silently defaulting to off)
- Add `--record <path>` CLI option that wraps the transport with
`RecordingTransport` to capture client→server messages as timestamped
JSONL
- Works in both pipe and socket modes
- Fix exit code: `loop.run()` returns non-zero after `uv_stop()`,
explicitly return 0 after clean shutdown
### Compile logging (`src/compile/compilation.cpp`)
- Print compile commands at debug log level
### Replay script (`tests/replay.py`)
- Timestamp-based pacing: sleeps between messages based on recorded
intervals, faithful to original editor session
- Automatic workspace path rewriting: infers repo root from script
location, rewrites absolute paths in trace so CI replay works without
extra arguments
- Handles server→client requests (workDoneProgress/create,
registerCapability, etc.) with default responses
- Waits for all pending responses before sending shutdown/exit
- Detects server exit mid-replay and fails pending futures immediately
instead of hanging
- Reports PASS/FAIL/SKIP with stderr tail on failure
### CI & config
- Add `smoke-test` pixi task and CI workflow step (runs after
integration tests)
- `.gitattributes`: mark `tests/smoke/*.jsonl` as `linguist-generated
binary` to suppress diffs
- Add sample trace file `tests/smoke/session.jsonl`
### VSCode extension
- Add restart command (`clice.restart`)
- Support `CLICE_MODE` env var to override mode setting (for debug
launch configs)
- Split launch configs into socket/pipe variants with
`--disable-extensions`
## Test plan
- [x] `python tests/replay.py tests/smoke/session.jsonl --clice
./build/RelWithDebInfo/bin/clice` passes locally
- [ ] CI smoke test passes on Linux/macOS/Windows

## Summary
Improve CMake build system: cleaner separation, compiler caching, and
release packaging.
### Toolchain & Build
- Clean up `toolchain.cmake` to only contain clang/lld-specific setup
(compiler paths, linker selection, llvm tools), allowing other
toolchains like GCC to work without it
- Add ccache (Linux/macOS) and sccache (Windows) support via toolchain
auto-detection
- Move project-universal flags (`-ffunction-sections`, `--gc-sections`,
`-static-libstdc++`, etc.) to `CMakeLists.txt` so they apply regardless
of toolchain
- Add `-fno-exceptions` to project compile options; fix `/EHs-c-` for
proper MSVC exception disabling
- Use MSVC/clang-cl frontend detection instead of `WIN32` for
MSVC-specific linker flags
- Declare missing options: `CLICE_USE_LIBCXX`, `CLICE_OFFLINE_BUILD`,
`CLICE_ENABLE_BENCHMARK`, `CLICE_RELEASE`
### Release Packaging (`cmake/release.cmake`)
- Strip debug symbols and produce separate symbol archives (`.debug` /
`.dSYM` / `.pdb`)
- Windows: copy PDB via `$<TARGET_PDB_FILE:clice>`; macOS: use
`copy_directory` for dSYM bundle
- Package clice binary + clang resource dir + config into distributable
tarball/zip
- `cmake/archive.cmake` helper for cross-platform archive creation
- Activated via `-DCLICE_RELEASE=ON` (auto-enables LTO)
### Code Cleanup
- Replace manual 40+ line source file list with `GLOB_RECURSE` for
clice-core
- Fix duplicate `include_resolver.cpp` entry
- Use build-time `add_custom_target` for clang resource dir copy
(instead of configure-time `file(COPY)`)
- Gate `scan_benchmark` behind `CLICE_ENABLE_BENCHMARK` option
### CI
- Add compiler cache with env var control (`CCACHE_DIR`/`SCCACHE_DIR`)
and `actions/cache` for persistence
- Proper cache lifecycle: zero-stats before build, show-stats +
stop-server after
- Stop sccache server before pixi cleanup to fix Windows EBUSY error
- Pass `CLICE_ENABLE_BENCHMARK=ON` in benchmark workflow
- Platform-specific ccache/sccache dependencies in pixi.toml
## Test plan
- [x] Local build (RelWithDebInfo) passes
- [x] Local release build (LTO + strip + pack) produces correct archives
- [ ] CI: Linux Debug/RelWithDebInfo
- [ ] CI: macOS Debug/RelWithDebInfo
- [ ] CI: Windows Debug/RelWithDebInfo
- [ ] CI: Benchmark (all platforms)
