# Contributing to CxLLM-XPC
Thanks for taking the time to contribute!
## Workflow
1. Open an issue describing the change before sending a PR for non-trivial work.
2. Fork / branch off `main`. Use a descriptive branch name (`feat/...`, `fix/...`).
3. Keep commits scoped and use **Conventional Commits** (`feat:`, `fix:`,
`docs:`, `refactor:`, `test:`, `chore:`).
4. Run `make lint` and `make test` before pushing.
5. Open a PR — CI must pass before review.
## Coding style
- Swift: `swiftformat` defaults + `swiftlint` rules from the umbrella repo.
- Objective-C / C / C++: clang-format `-style=Google`.
- No tabs in Swift; 4-space indent in C/C++.
## Code of conduct
By contributing you agree to abide by the project's Code of Conduct
(see the umbrella `cxllm-code` repo).

# CxLLM-XPC
> CxLLM XPC service
Objective-C XPC service that brokers privileged operations between the CxLLM host application and the kernel surface.
[![ci](https://git.cxllm-studio.com/CxAI-LLM/CxLLM-XPC/actions/workflows/ci.yml/badge.svg)](https://git.cxllm-studio.com/CxAI-LLM/CxLLM-XPC/actions)

[![category](https://img.shields.io/badge/category-xpc-service-1F6FEB)](#)
## Overview
`CxLLM-XPC` is part of the **CxLLM** product family — a layered runtime that
spans Apple kernel extensions, user-space frameworks, host applications, and
spatial / web surfaces. This module focuses on **xpc-service** concerns and is
intentionally narrow so that the CxLLM monorepo can compose targets without
pulling in unrelated dependencies.
## Repository layout
- `CxLLM-XPC/` — primary source folder (matches the Xcode group / SwiftPM root).
- `CxLLM-XPC.xcodeproj` — Xcode project (where applicable).
- `Makefile` — common entry points (`build`, `test`, `lint`, `clean`).
- `.github/workflows/ci.yml` — CI pipeline (Xcode build + lint).
- `docs/` — architecture notes and ADRs.
## Quick start
```bash
# Build (defaults to Debug for the host platform):
make build
# Run the full test suite (unit + UI where applicable):
make test
# Static analysis + format check:
make lint
```
## Versioning
This module follows [Semantic Versioning 2.0](https://semver.org/) and is
released in lock-step with the umbrella **CxLLM** product line. See
[`CHANGELOG.md`](CHANGELOG.md) for the user-facing change log.
## Security
Please report security issues per [`SECURITY.md`](SECURITY.md). Do **not**
open public issues for vulnerabilities.

# Architecture — CxLLM-XPC
> CxLLM XPC service
## Goals
- Provide a focused, well-tested xpc-service surface for the CxLLM family.
- Stay deployable on its own (no monorepo coupling).
- Keep the public ABI small and explicitly versioned.
## Boundaries
```text
+----------------------+
client --> | CxLLM-XPC |
+----------+-----------+
|
v
CxLLM runtime / kernel
```
## Decisions
- See `docs/adr/` for Architecture Decision Records.

# 1. Record architecture decisions
## Status
Accepted
## Context
We need a lightweight, append-only log of architectural choices.
## Decision
Use Markdown ADRs in `docs/adr/`, numbered sequentially.
## Consequences
Future maintainers can read the chain of decisions without spelunking PR history.
