## 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
PCH and PCM artifacts are now cached to disk at
`.clice/cache/{pch/,pcm/}` with content-addressed filenames, so they
survive server restarts. Dependency metadata is persisted in
`cache.json` (using eventide serde) with a shared path table for
deduplication.
### Key changes
- **protocol.h**: `output_path` field on `BuildPCHParams` /
`BuildPCMParams` so master specifies where workers write
- **stateless_worker.cpp**: Atomic write via `.tmp` + `fs::rename`;
`CompilationUnit` destroyed before rename to flush the file to disk;
fallback to temp file when `output_path` is empty (unit tests)
- **master_server.h**: `PCMState` struct, `pcm_states` map,
`load_cache()` / `save_cache()` / `cleanup_cache()` methods
- **master_server.cpp**: Cache lifecycle — load from `cache.json` on
startup, save after each PCH/PCM build and on exit; deterministic path
computation (`xxh3` preamble hash for PCH, module name + source path
hash for PCM); stale files (>7 days) cleaned on startup; `cache.json`
uses shared path table to avoid redundant storage of header paths across
entries
- **filesystem.h**: `fs::rename()` helper; `ThreadSafeFS` broadened to
match `.pch` extension instead of `preamble-` prefix
- **tests**: 11 new integration tests covering PCH/PCM persistence,
cross-session reuse, staleness detection, shared preamble dedup, and
restart survival; unit tests updated with `output_path`
### Naming scheme
- **PCH**: `.clice/cache/pch/<016x(xxh3(preamble))>.pch`
- **PCM**:
`.clice/cache/pcm/<module_name>-<016x(xxh3(source_path))>.pcm`
## Test plan
- [x] Unit tests — 448 passed
- [x] Integration tests — 92 passed (including 11 new persistent cache
tests)
- [x] Smoke tests — 1 passed

## Summary
- Add `ensure_pch()` helper to MasterServer that builds/reuses
precompiled headers via stateless workers, with preamble hash-based
staleness detection (xxh3_64bits)
- Fix `BuildPCHParams` to carry `preamble_bound` so the stateless worker
truncates content at the preamble boundary (fixes redefinition errors
when PCH included full file)
- Wire PCH into both `run_build_drain` (stateful compile path) and
`forward_stateless` (completion/signatureHelp path)
- Add PCH state cleanup on `didClose` and hash invalidation on `didSave`
## Test plan
- [x] 398 unit tests pass (including 6 new PCH tests: PreambleHash x3,
PCHWorker x2, BuildPCHRequest assertion)
- [x] 5 new integration tests pass (`test_pch.py`: diagnostics on open,
body edit recompile, no-include file, hover with PCH, completion with
PCH)
- [x] 21 existing integration tests pass unchanged
- [x] Build succeeds with 0 errors

## Summary by CodeRabbit
* **New Features**
* Precompiled header (PCH) caching to speed compilations and reduce edit
latency
* Automatic attachment of cached PCH to compile requests, improving
hover and completion responsiveness
* Module-aware completions expanded to include available module
artifacts from other files
* **Bug Fixes**
* PCH cache cleared on file close; saving now triggers broader PCH
invalidation to prevent stale PCH use
* **Tests**
* Added unit and integration tests exercising PCH build, reuse, and
editor interactions
