Author, instantiate, and execute agentic QA test case plans for Elodin releases. Use when the user asks to create a QA plan, test case plan, or release test checklist, add or edit test cases, or run/execute a QA test plan for a release.
Develop and calibrate simulations against experimental truth data using elodin monte-carlo. Use when vendoring real telemetry as a reference profile, adding a truth-replay ghost entity, writing campaign specs/hooks and run scoring, reconstructing missing data channels from physics, or iterating on guidance and physics models with campaign feedback.
Deploy and configure AlephOS on flight computers, write flight software services, and manage NixOS modules for the Aleph platform. Use when working with aleph/, deploying to Jetson Orin hardware, writing NixOS modules, flashing firmware, or composing a flight software stack.
Contribute to the Elodin Editor, the 3D viewer and graphing tool. Use when editing files in libs/elodin-editor/ or apps/elodin/, working on the Bevy/Egui UI, modifying viewport rendering, telemetry graphs, video streaming, KDL schematics, or the command palette.
Create and modify physics simulations using the Elodin Python SDK. Use when writing or editing simulation Python files, defining components or systems, spawning entities, configuring 6DOF physics, setting up visualization, or integrating with SITL/HITL workflows.
Work with the Cranelift JIT MLIR backend. Use when modifying libs/cranelift-mlir/, adding new StableHLO ops, debugging simulation correctness issues, running the checkpoint diagnostic tool, or working on the pointer-ABI tensor runtime.

Key integration points:
brew install just / apt install just)git lfs install globally)Always work inside the Nix shell. It provides Rust, Python, C/C++ toolchains, cloud tools, and git-lfs.
nix develop # Enter unified dev shell
nix develop --command "cargo build" # One-off command
just install
# Run an example
elodin editor examples/three-body/main.py
All changes must pass these before merge. See ci-checks.md for details.
cargo fmt # Rust formatting
cargo test # Rust tests
cargo clippy -- -Dwarnings # Rust lints (warnings = errors)
ruff format --check && ruff check --fix # Python formatting + lints
alejandra # Nix formatting
The Cargo workspace has 57 members. Key crates by area:
| Area | Crates |
|---|---|
| Simulation | nox, elodin-macros, nox-py, nox-frames, cranelift-mlir |
| Database | db, db/cli, db/eql, db/tests |
| Telemetry | impeller2, impeller2/{bevy,stellar,bbq,frame,kdl,wkt} |
| Editor | elodin-editor, apps/elodin |
| Runtime | stellarator, stellarator/{buf,macros,maitake} |
| Flight SW | roci, roci/{macros,adcs} |
| FSW Apps | serial-bridge, mekf, msp-osd, lqr, blackbox, gstreamer, video-streamer |
| Utilities | wmm, s10, video-toolbox |
Always run commands from the repo root. This prevents path confusion across the many workspace members and aligns with how CI runs.
