libuipc PR Review

Architecture primer (read before reviewing)

libuipc is a GPU-accelerated Incremental Potential Contact (IPC) simulation library (C++20 + optional Python/pybind11).

Layer split:

Layer	Path	Role
Core	`src/core/`, `include/uipc/`	Engine lifecycle, Scene/World, geometry attribute ECS
Geometry	`src/geometry/`	Mesh algorithms; libigl, TBB, Octree, METIS
Constitution	`src/constitution/`	Material / constraint implementations
I/O	`src/io/`	Scene + mesh serialisation
Sanity check	`src/sanity_check/`	Pre-sim scene validation
Backends	`src/backends/<name>/`	Physics engines as runtime-loaded MODULE DLLs
Pybind	`src/pybind/`	Thin pybind11 wrapper; mirrors C++ submodules

Backend plugin ABI (src/backends/common/module.h):

Exports: uipc_init_module, uipc_create_engine, uipc_destroy_engine
Base classes: SimEngine → ISimSystem → subsystem folders (affine_body/, finite_element/, contact_system/, collision_detection/, etc.)
RMR (Reporter–Manager–Receiver) data-oriented design; avoid heavy OOP in backend code

CUDA backend subsystems (most review-sensitive): affine_body/, finite_element/, contact_system/, collision_detection/, distance_system/, active_set_system/, inter_primitive_effect_system/, engine/ (Newton + augmented-Lagrangian step in advance_al.cu)

Workflow

1. Checkout and fetch metadata

gh pr checkout <PR_NUMBER>
gh pr view <PR_NUMBER> --json title,body,author,baseRefName,headRefName,headRefOid,repository,url,additions,deletions,changedFiles
gh pr diff <PR_NUMBER> --name-only

2. Present summary to the human reviewer

## PR #<N>: <title>
Author: <author>   Branch: `<head>` → `<base>`
URL: <url>
Stats: +<add> / -<del> across <N> files

### Description
<body>

### Files to review  (grouped by subsystem)
#### Backend — CUDA physics
  src/backends/cuda/affine_body/...
  src/backends/cuda/finite_element/...
  ...
#### Core / Public API
  include/uipc/...
  src/core/...
#### Geometry / Constitution
  src/geometry/...   src/constitution/...
#### Python bindings
  src/pybind/...   python/src/uipc/...
#### Build / CMake
  CMakeLists.txt   src/backends/.../CMakeLists.txt
#### Tests
  apps/tests/...   python/tests/...

3. AI review — libuipc-specific checklist

Run gh pr diff <PR_NUMBER> and check every area below that is touched.

Fast fail

All expected internal invariants are checked with UIPC_ASSERT where feasible
All user-facing inputs are validated with UIPC_ASSERT_THROW

C++20 style

C-style code is forbidden unless unavoidable (e.g., DLL export signatures)
Raw pointer parameters are forbidden unless unavoidable; prefer span<T>
const std::string& parameters are forbidden; use std::string_view instead
Multiple inheritance is forbidden; separate concerns into distinct classes

CUDA / GPU code

GPU buffer arguments use muda::BufferView / muda::TripletMatrixView (or equivalent view types) instead of raw pointers
Raw pointer parameters are forbidden in device code unless unavoidable

Constitution / material

New constitutions implement required IConstitution-family interface
Material parameters validated / clamped (no negative stiffness, density, etc.)

Public C++ API (`include/uipc/`)

No breaking changes to public headers without a version bump or deprecation notice
New public classes/functions follow existing naming: CamelCase types, snake_case functions, m_ prefix for members
#pragma once present; no <windows.h>-style global macros leaked

C++ style (`.clang-format` enforced)

4-space indent, 80-column limit
Allman braces ({ on its own line)
Left-aligned pointers (int* p, not int *p)
No using namespace std; in headers

CMake

New backend follows uipc_add_backend(name) macro in src/backends/CMakeLists.txt
New CMake options added to the root CMakeLists.txt option block with sensible defaults
file(GLOB ...) patterns extended if new source subdirs added

Python bindings (`src/pybind/` + `python/`)

Check whether new features expose a public API that should be mirrored in the Python bindings
New C++ types exposed via matching pybind submodule (mirrors C++ namespace)
__init__.py import chain not broken (pyuipc → init() → config["module_dir"])
Python-side tests added under python/tests/ for new pybind surface

Tests

C++ tests use Catch2 macros; added via uipc_add_test in the appropriate apps/tests/<subsystem>/CMakeLists.txt
Regression tests added for bug fixes

4. Output format

Each finding must have a sequential number (1, 2, 3 … across all severity tiers) and a clickable local file link constructed from the absolute repo path + relative file path. Use this markdown link format for every citation:

[filename.ext:LINE](ABSOLUTE_REPO_PATH/relative/path/to/file.ext)

For example, if the repo is at /home/user/libuipc and the file is src/backends/cuda/affine_body/foo.cu at line 42:

[foo.cu:42](/home/user/libuipc/src/backends/cuda/affine_body/foo.cu)

Full output template:

### Checklist coverage
(tick the items above that were verified or N/A)

5. Post comments via `gh` (when asked)

General review comment / request changes / approve:

gh pr review <PR_NUMBER> --comment   --body "..."
gh pr review <PR_NUMBER> --request-changes --body "..."
gh pr review <PR_NUMBER> --approve   --body "LGTM"

Inline comment on a specific line:

gh api repos/<OWNER>/<REPO>/pulls/<PR_NUMBER>/comments \
  --method POST \
  -f path="<FILE_PATH>" \
  -f body="Your comment" \
  -F line=<LINE_NUMBER> \
  -f side="RIGHT" \
  -f commit_id="<HEAD_REF_OID>"

Run gh auth status first if commands fail.
