+# clice — Project Guide
+
+## Project Overview
+
+clice is a next-generation C++ language server (LSP) built on LLVM/Clang, targeting modern C++ (C++20/23). It uses a multi-process architecture with a master server coordinating stateless and stateful workers.
+
+## Core Correction Patterns — Lessons from Past Interactions
+
+The following patterns were extracted from extensive real-world collaboration. These are recurring mistakes that MUST be avoided. Read them carefully — they represent hard-won lessons, not hypothetical concerns.
+
+### Pattern 1: Misjudging Real-World Priorities
+
+AI tends to optimize whatever metric looks most impressive, rather than what actually matters in the user's real scenario.
+
+**Example**: During performance optimization, the AI proudly reported "hot cache is 4-7x faster!" — but the function in question runs at LSP server startup, which is ALWAYS a cold start. Optimizing hot cache was completely meaningless.
+
+**Rule**: Before optimizing or analyzing anything, first understand the REAL usage scenario. Ask yourself: "When does this code actually run? What does the user actually experience?" Do not chase metrics that look good on paper but are irrelevant in practice.
+
+### Pattern 2: Pushing Without Local Verification
+
+The most common and most damaging pattern. AI proposes a fix, pushes it immediately, CI fails, then another fix, push, fail again — wasting CI cycles and the user's time.
+
+**Rule**: NEVER push code that you haven't verified locally. Before every push:
+
+- Build locally with the same configuration CI uses.
+- Run the relevant tests locally and confirm they pass.
+- If you cannot reproduce the CI environment locally, say so — do not just "try and see."
+- "It compiles" is NOT sufficient. Tests must pass.
+
+### Pattern 3: Superficial Refactoring
+
+When asked to refactor, AI tends to do mechanical code movement (copy functions from A to B) without understanding the deeper design intent (ownership, responsibility boundaries, API cleanliness).
+
+**Example**: When splitting `MasterServer` into `Workspace` and `Session`, the AI moved functions but kept ugly APIs like `f(path_id, sessions_map)` instead of the clean `f(Session&)` that the refactoring was meant to achieve.
+
+**Rule**: When refactoring, understand the WHY. Ask: "What design problem is this refactoring solving?" If you're just moving code around without improving the abstractions, you're not refactoring — you're rearranging deck chairs.
+
+### Pattern 4: Fixing Only the Immediate Instance, Not the Pattern
+
+When given a cleanup instruction, AI applies it to the single file or function currently being discussed, ignoring all other occurrences in the project.
+
+**Example**: User says "remove decorative `===` comment separators." AI removes them from `workspace.cpp` only. User has to say: "The other files too!"
+
+**Rule**: When given a cleanup or style instruction, apply it project-wide. Use `Grep` to find ALL occurrences and fix them all in one pass. Think: "Where else does this pattern appear?"
+
+### Pattern 5: Never Skip, Disable, or Work Around Failing Tests
+
+When stuck on a difficult bug (especially flaky CI, race conditions, platform-specific issues), AI may propose marking tests as `continue-on-error`, skipping them, or adding `expected-failure` annotations to make CI green.
+
+**Rule**: This is ABSOLUTELY FORBIDDEN. If a test fails, fix the root cause. There are ZERO exceptions. Skipping a test to make CI green is not "fixing" — it is hiding a bug. If you ever find yourself thinking "maybe we should just skip this test," stop and reconsider your approach entirely.
+
+### Pattern 6: Excessive Confirmation Seeking vs. Premature Execution
+
+AI oscillates between two extremes: asking "should I do X?" for every trivial decision, or silently executing major changes without confirmation.
+
+**Rule**: Calibrate based on reversibility and impact:
+
+- **Small, reversible changes** (formatting, renaming a local variable, adding a test): just do it.
+- **Architecture decisions, API changes, large refactors**: propose the plan first, wait for confirmation.
+- **Pushing to remote, creating PRs, modifying CI**: always confirm.
+- When the user says "go ahead" or "do it," execute fully without asking again mid-way.
+
+## Code Reuse & Understanding Before Implementation
+
+**This is the single most important rule in this project.** Before writing ANY new code, you MUST thoroughly read and understand the existing codebase first. This project has a rich set of utilities, abstractions, and patterns already in place — duplicating them wastes effort and creates maintenance burden.
+
+Concrete requirements:
+
+1. **Read before you write.** Before implementing a feature or fix, explore the relevant modules in `src/`. Search for existing helpers, utilities, and patterns that solve the same or similar problems. Use `Grep`, `Glob`, and `Agent` tools to investigate thoroughly — do not assume something doesn't exist just because you haven't seen it yet.
+
+2. **Reuse existing infrastructure.** This project already has:
+   - A `Lexer` class (`src/syntax/lexer.h`) — do not hand-write token scanning logic.
+   - A `PositionMapper` for source location conversion — do not reimplement offset-to-line/column math.
+   - `CompilationUnitRef` methods (`decompose_location`, `decompose_range`, `file_path`, `directives`, etc.) — use them instead of raw Clang APIs.
+   - `SemanticVisitor` for AST traversal — extend it, do not write custom recursive AST walkers.
+   - `Tester` framework for unit tests with VFS, annotation support, and multi-phase compilation — use it, do not create ad-hoc test setups.
+   - Utility functions in `src/support/` — check there before writing new helpers.
+
+3. **Follow established patterns.** When adding a new feature (e.g., a new LSP request handler), look at how 2-3 existing features of the same kind are implemented. Match their structure: same file organization, same function signatures, same error handling patterns. If every other feature in `src/feature/` follows a certain pattern, yours should too.
+
+4. **Do not reinvent what the project already has.** If you find yourself writing a helper function that feels generic (string manipulation, path handling, JSON serialization, source range conversion), STOP and search the codebase first. There is a high probability it already exists. Creating duplicates leads to inconsistencies and bugs when one copy gets updated but the other doesn't.
+
+5. **When in doubt, ask.** If you're unsure whether an existing utility covers your use case or whether to extend an existing abstraction vs. create a new one, ask the user rather than guessing.
+
+## Source Layout
+
+- `src/server/` — LSP server core: master server, compiler, indexer, stateful/stateless workers
+- `src/feature/` — LSP feature implementations: hover, completion, document links, semantic tokens, etc.
+- `src/compile/` — Compilation orchestration: compilation unit, directives, diagnostics
+- `src/index/` — Symbol indexing: TUIndex, ProjectIndex, MergedIndex, include graph
+- `src/semantic/` — Semantic analysis: symbol kinds, relations, AST visitor, template resolver
+- `src/syntax/` — Lexer, scanner, token types, dependency graph
+- `src/command/` — CLI parsing, compilation database, toolchain detection
+- `src/support/` — Utilities: logging, filesystem, JSON, string helpers
+
+## Build System
+
+- Uses **pixi** for environment management and **CMake + Ninja** for building.
+- Two build types: `Debug` and `RelWithDebInfo` (default).
+- Build output goes to `build/[type]/`.
+- See `/build`, `/test`, `/format` commands for common operations.
+
+## Commit Message Format
+
+Use **conventional commits** — enforced by CI:
+
+```
+<type>(<scope>): <short description>
+```
+
+- **Types**: `feat`, `fix`, `refactor`, `chore`, `docs`, `ci`, `test`
+- **Scopes**: match `src/` subdirectories or feature names, e.g. `completion`, `server`, `index`, `tests`, `document links`
+- Keep the subject line under 70 characters.
+
+## Tests
+
+Three types of tests, all must pass before committing:
+
+- **Unit tests** (`tests/unit/`): C++ tests using the project's own test framework. Test names should be at most 4 words.
+- **Integration tests** (`tests/integration/`): Python pytest tests that start a real clice server and communicate via LSP.
+- **Smoke tests** (`tests/smoke/`): Replay recorded LSP sessions via `tests/replay.py`.
+
+### Integration Test Style
+
+- Keep tests concise. Do NOT write large comment blocks explaining the test layout or expected behavior.
+- Use descriptive test function names and short inline comments only where logic is non-obvious.
+
+## Pre-PR Review
+
+Before opening a PR, launch **3 parallel subagents** to review the diff independently:
+
+1. **Correctness reviewer**: Check for logic errors, edge cases, undefined behavior, and off-by-one mistakes.
+2. **Style reviewer**: Verify the code follows this project's naming conventions, coding style, and CLAUDE.md rules.
+3. **Test reviewer**: Confirm test coverage is adequate — new functionality has tests, edge cases are covered, and no existing tests were broken or weakened.
+
+Each agent should read the full diff (`git diff main...HEAD`) and report issues. Fix all reported issues before opening the PR.
+
+## Pre-commit Checklist
+
+Before committing code, you MUST:
+
+1. **Run `pixi run format`** to format all source files.
+2. **Pass all three types of tests:**
+   - Unit tests: `pixi run unit-test [type]`
+   - Integration tests: `pixi run integration-test [type]`
+   - Smoke tests: `pixi run smoke-test [type]`
+3. **All test failures must be fixed before committing.** This is a HARD REQUIREMENT with NO exceptions:
+   - If a test fails, it MUST be fixed before you commit. Do NOT commit with known failures.
+   - Do NOT skip, disable, or mark tests as expected-failure to work around breakage.
+   - Do NOT argue "this test was already broken before my changes" — if it fails on your branch, it is YOUR responsibility to fix it before committing. The main branch CI is green; any failure on your branch is caused by your changes, period.
+   - Do NOT defer fixing to a follow-up PR. Fix it NOW, in this branch, before committing.
+
+---
+
+## C++ Coding Style
+
+### Template & Type Traits
+
+- Do NOT blindly add `std::remove_cvref_t` on every template parameter. Understand C++ template argument deduction rules:
+  - `template<typename T> void f(T x)` — `T` is always deduced as a non-reference, non-cv-qualified type. No need for `remove_cvref_t`.
+  - `template<typename T> void f(T& x)` — `T` is deduced as the referred-to type (possibly cv-qualified, but never a reference). No need for `remove_cvref_t` to strip references.
+  - `template<typename T> void f(const T& x)` — `T` is deduced as a non-const, non-reference type. No need for `remove_cvref_t`.
+  - `template<typename T> void f(T&& x)` — **forwarding reference**: `T` CAN be deduced as an lvalue reference (e.g., `int&`). This is the ONLY case where `std::remove_cvref_t<T>` is needed to get the bare type.
+  - Class template parameters and return types are also never deduced as references; don't add `remove_cvref_t` on them either.
+
+### Type Traits & Concepts (C++20/23)
+
+- This project targets C++20/23. Use variable templates directly for type traits — do NOT use the old pattern of wrapping a class template static member in a variable template. Prefer:
+
+  ```cpp
+  // Good: directly specialize a variable template
+  template<typename T>
+  inline constexpr bool is_my_type_v = false;
+
+  template<>
+  inline constexpr bool is_my_type_v<MyType> = true;
+  ```
+
+  ```cpp
+  // Bad: unnecessary class template wrapper
+  template<typename T>
+  struct is_my_type : std::false_type {};
+
+  template<>
+  struct is_my_type<MyType> : std::true_type {};
+
+  template<typename T>
+  inline constexpr bool is_my_type_v = is_my_type<T>::value;
+  ```
+
+- When defining a concept that checks a type trait, do NOT add `std::remove_cvref_t` unless you specifically intend the concept to see through references/cv-qualifiers. If the concept is meant for a bare type, just use `T` directly — the caller is responsible for passing the right type.
+
+  ```cpp
+  // Good
+  template<typename T>
+  concept MyTrait = is_my_type_v<T>;
+
+  // Bad: unnecessary remove_cvref_t
+  template<typename T>
+  concept MyTrait = is_my_type_v<std::remove_cvref_t<T>>;
+  ```
+
+### Naming Conventions
+
+- **Variables, member fields, function names**: `snake_case`. Class member fields do NOT use any special suffix/prefix (no trailing `_`, no `m_` prefix).
+- **Class names, template parameter names, enum names**: `PascalCase`. Exception: some class names also use `snake_case` — follow the existing style in the project.
+- **Enum values**: `PascalCase`.
+
+### String Literals
+
+- Prefer C++11 raw string literals `R"(...)"` over escaped strings. Avoid `\"`, `\\`, `\n` in string literals when a raw literal is cleaner.
+
+### Error Handling
+
+- **Prefer `if` with init-statements to tightly scope error variables**, but avoid them when they compromise code readability or flatten control flow.
+- **Omit redundant conditions:** If the error type provides an `operator bool` or evaluates implicitly (e.g., standard error codes, custom error wrappers), omit the redundant condition check.
+- **Avoid forced `else` branches:** If scoping the variable inside the `if` requires you to introduce an `else` block for the success path (especially when returning early on error), declare the variable in the local scope instead to keep the control flow flat.
+
+```cpp
+// Good: Omit redundant condition when the type has operator bool
+if (auto err = foo()) {
+    /* handle error */
+}
+
+// Bad: Redundant condition check
+if (auto err = foo(); err) {
+    /* handle error */
+}
+
+// Good: Use init-statement when a custom condition is required,
+// AND the variable isn't needed outside the if-statement
+if (auto result = foo(); !result.has_value()) {
+    /* handle error */
+}
+
+// --- Scope and Control Flow Considerations ---
+
+// Bad: Using init-statement forces an 'else' block because 'result'
+// goes out of scope, leading to nested/redundant code.
+if (auto result = get_data(); !result.has_value()) {
+    return result.error();
+} else {
+    process(result.value()); // Success path is forced into a nested block
+}
+
+// Good: Declare as a regular local variable to allow early exit
+// and keep the success path un-nested (flat control flow).
+auto result = get_data();
+if (!result.has_value()) {
+    return result.error();
+}
+process(result.value());
+```
+
+### Style
+
+- Prefer `[[maybe_unused]]` over `(void)` for intentionally unused variables or parameters.
+
+### Modern C++ Usage
+
+- Use C++20/23 APIs whenever possible. Do NOT use `<iostream>` facilities (`std::cout`, `std::cin`, `std::cerr`, etc.). Also do NOT use C-style I/O (`printf`, `fprintf`, etc.).
+- Prefer `std::ranges` / `std::views` APIs over raw loops and traditional `<algorithm>` calls.
+- If the project depends on LLVM, prefer LLVM's efficient data structures (e.g., `llvm::SmallVector`, `llvm::DenseMap`, `llvm::StringMap`, `llvm::StringRef`) over their `std` counterparts when appropriate.
+
+### Parameter Passing Preferences
+
+- For string parameters, prefer `llvm::StringRef` > `std::string_view` > `const std::string&`.
+- For array/span parameters, prefer `llvm::ArrayRef` > `std::span` > `const std::vector&`.
