## Summary
- The `eventide` dep was renamed to
[kotatsu](https://github.com/clice-io/kotatsu) with a broad rename of
CMake identifiers, namespaces, header paths, and a few module reorgs
(`serde` → `codec`, `reflection` → `meta`, `common` → `support`). Align
clice to the new names.
- CMake: FetchContent target, option prefix (`ETD_*` → `KOTA_*`,
`ETD_SERDE_*` → `KOTA_CODEC_*`), target names
(`eventide::{ipc::lsp,serde::toml,deco,zest}` →
`kota::{ipc::lsp,codec::toml,deco,zest}`).
- Namespaces: `eventide::` → `kota::`, `eventide::serde::` →
`kota::codec::`, `eventide::refl::` → `kota::meta::`. The short `et`
alias is dropped — all usages now spell `kota::` directly.
- Headers: `eventide/*` → `kota/*`, including special cases
`serde/serde/raw_value.h` → `codec/raw_value.h`, `ipc/json_codec.h` →
`ipc/codec/json.h`, `common/meta.h` → `support/type_traits.h`,
`common/ranges.h` → `support/ranges.h`.
- Kotatsu split `JsonPeer` / `BincodePeer` out of `ipc/peer.h` into the
codec-specific headers; added `kota/ipc/codec/{json,bincode}.h` includes
where those types are used.
- Depends on clice-io/kotatsu#110 (already merged) to prevent `-Wall
-Wextra -Werror` from transitively propagating out of
`kota::project_options`.
## Test plan
- [x] `pixi run unit-test RelWithDebInfo` — 518/518 pass (9 skipped,
unchanged from main)
- [x] `pixi run integration-test RelWithDebInfo` — 119/119 pass
- [x] `pixi run smoke-test RelWithDebInfo` — 2/2 pass
- [x] `pixi run format` clean
## Notes
- `tests/smoke/rapid_edit.jsonl` was intentionally left untouched: the
embedded `#include "eventide/..."` strings are frozen snapshots of file
contents the client sent at record time, not clice source.

## Summary by CodeRabbit
* **Chores**
* Updated internal dependencies from `eventide` to `kota`, including
async runtime, IPC transport, serialization codec, and metadata
libraries.
* Updated build configuration and CMake variables to align with the new
dependency.
* **Refactor**
* Migrated internal implementation to use `kota` namespace and APIs
throughout the codebase.

## Summary
- **Extract `Indexer` class** — owns all index state (ProjectIndex,
MergedIndex shards, OpenFileIndex) and query methods (definition,
references, call/type hierarchy, workspace symbol search)
- **Extract `Compiler` class** — owns document state, PCH/PCM cache,
compile argument resolution, header context, `ensure_compiled`, and
worker forwarding
- **MasterServer is now a pure LSP handler registration layer** (~700
lines, down from ~3200)
- **`MergedIndexShard`** wraps `index::MergedIndex` with a lazily-cached
PositionMapper; `OpenFileIndex` gains matching
`find_occurrence()`/`find_relations()` APIs — callers get pre-converted
LSP ranges directly
- **Indexer returns typed values** (`vector<Location>`,
`vector<CallHierarchyIncomingCall>`, etc.) instead of pre-serialized
JSON, fixing the references handler from JSON string surgery to simple
vector concatenation
- **Fix**: duplicate `workspace/symbol` loop in the original code
## Test plan
- [x] 465 unit tests pass
- [x] 113 integration tests pass
- [x] 2/2 smoke tests pass
- [x] `clang-format` applied

## Summary by CodeRabbit
* **New Features**
* Server-side C++ compilation orchestration (module & precompiled header
builds) with LSP-integrated document handling.
* **Improvements**
* Deterministic, persistent, dependency-aware caching to avoid redundant
rebuilds and speed up incremental work.
* Better cross-file indexing and navigation, improved diagnostics and
more reliable include/import-aware completions.
* **Tests**
* Unit tests updated to the unified worker query/build request shapes.

## Summary
Fix two data races in the stateful worker that caused spurious
"redefinition" errors during rapid edits, and remove a didChange
workaround that is no longer needed after clice-io/eventide#95.
### stateful_worker.cpp
**Compile handler**: move `params` → `doc` field copy **after**
`strand.lock()`. Previously the copy happened before the lock, so a
concurrent Compile request waiting on the strand could overwrite
`doc.text` while `et::queue` was reading it on the thread pool:
```
T1: Compile A → doc.text = text_A → lock → et::queue reads doc.text
T2: Compile B → doc.text = text_B → waits for strand (overwrites!)
T3: et::queue sees text_B instead of text_A → PCH/text mismatch
```
**DocumentUpdate handler**: only mark `dirty`, stop modifying
`doc.text`/`doc.version`. The event loop notification can fire while
`et::queue` work is running on the thread pool — writing `doc.text` from
one thread while reading it from another is a data race.
### master_server.cpp
Remove the `{0,0}-{0,0}` range workaround for whole-document
`didChange`. eventide's variant deserialization now correctly rejects
`TextDocumentContentChangePartial` when the `range` field is absent
(clice-io/eventide#95), so `TextDocumentContentChangeWholeDocument` is
matched as intended.
### protocol.h
Remove `text` field from `DocumentUpdateParams` — the worker no longer
needs it since DocumentUpdate only sets the dirty flag.
### Integration tests (+312 lines)
Extend test_staleness.py from 5 to 14 tests covering document lifecycle:
- `didChange` body edit → recompilation with updated diagnostics
- `didChange` preamble edit → PCH rebuild + clean recompilation
- `didClose` + reopen → compiles fresh from disk
- `didClose` → hover returns None
- `didSave` header → dependent file recompiles
- `didSave` module → CompileGraph dependents invalidated
## Test plan
- [x] 422 unit tests pass (426 on CI with extra test suites)
- [x] 14 integration tests pass locally
- [x] Depends on clice-io/eventide#95 (merged)

## Summary by CodeRabbit
* **New Features**
* Smaller document-update notifications sent to background workers (only
path and version).
* **Bug Fixes**
* Reduced races and unnecessary work between update and compile flows.
* Prevented notifications from overwriting in-memory document text,
improving state consistency.
* Safer concurrent handling to avoid mid-request eviction of active
documents.
* **Tests**
* Added integration tests for staleness, dependency propagation, and LSP
lifecycle.
* Updated unit tests to match revised update behavior.

## Summary
- **CMake-based CDB generation for module tests**: Replace hand-written
compile_commands.json with CMakeLists.txt (CMake 3.28 `FILE_SET
CXX_MODULES`) in all 26 `tests/data/modules/*/` directories. CDB is
generated on-the-fly via `cmake -G Ninja` during test setup.
- **`@pytest.mark.workspace()` decorator**: Introduce a marker + fixture
pattern so tests declare their workspace via decorator and receive a
resolved `workspace` path. The fixture auto-generates CDB when a
CMakeLists.txt is present.
- **`CliceClient` helper methods**: Add `initialize()`, `open()`,
`wait_diagnostics()`, and `open_and_wait()` to reduce boilerplate across
all test files.
- **Use `asyncio_mode = "auto"`**: Switch from `@pytest_asyncio.fixture`
+ `@pytest.mark.asyncio` to `@pytest.fixture` + auto mode for proper
Pylance type inference on fixtures.
- **Test cleanup**: Remove redundant section separators and docstrings,
delete `tests/pyproject.toml` (config moved to `pytest.ini`).
- **Format task**: Add `.cppm` to `format-cpp` glob pattern.
- **CI fix**: Disable `CMAKE_CXX_SCAN_FOR_MODULES` and prefer pixi
clang++ to fix macOS CI where CMake rejects module scanning.
## Test plan
- [x] All 26 module test directories have CMakeLists.txt with FILE_SET
CXX_MODULES
- [x] generate_cdb() produces valid compile_commands.json with module
flags
- [x] Integration tests pass locally
- [ ] CI passes on all platforms (Linux, macOS, Windows)

## Summary by CodeRabbit
* **Tests**
* Unified fixtures and client workflow: new init/open/wait helpers,
workspace marker support, bounded diagnostics waiting, CMake-based
compilation-database generation, and directory-backed temp-file
workflows; enabled asyncio test mode.
* **Chores**
* Added many C++20 module test projects and test data; removed prior
test pyproject in favor of pytest config; updated formatter to include
.cppm files.
* **Style**
* Reformatted many module/source implementations to consistent
multi-line function bodies.
