# AGENTS.md — otko
Pre-alpha SAP2000-style desktop GUI for OpenSeesPy. Python 3.10+; **Windows requires 3.12+** (`openseespywin==3.8.0.0` has no 3.11 wheel). Solver pinned: `openseespy==3.8.0.0`.
## Install
```bash
pip install -e ".[gui,dev]" # desktop: Qt + PyVista + dev tools
pip install -e . # headless: core + services only, no Qt (scripts, notebooks, web backends)
python -m otko # launch GUI (src/otko/app.py:run)
```
`scipy`/`pandas` in `[gui]` extras are phantom deps (not imported as of 2026-06) — do not add imports expecting them.
## Architecture (enforced in review — see PR template)
Strict one-way MVVM + services: `views → viewmodels → services → core`.
- `core/` (entities: `project.py`, `geometry/`, `materials/`, `sections/`, `loads/`, `analysis/`, `catalog/`): stdlib + numpy + pydantic only. **No Qt, no openseespy. Period.**
- `services/` (`opensees_runner.py`, `persistence.py`, `results.py`, ...): may use core + h5py + openseespy. **No Qt.**
- `views/`: PySide6/pyvistaqt only. **No direct `import openseespy`** — go through a service.
- `viewmodels/` bridges core↔Qt (signals, `QUndoStack`); `commands/` holds `QUndoCommand` subclasses.
- Rules: public functions need type hints + docstring; new domain entities go through Pydantic validation; ops >50 ms run off the GUI thread (`AnalysisWorker` in QThread, cancel via `isInterruptionRequested()`, results cross threads as lightweight `ResultsHandle` to HDF5).
Runner emits OpenSeesPy commands in fixed order (`docs/architecture.md`): `wipe → model → node → fix → material → section → geomTransf → element → timeSeries → pattern/load → recorder → system/numberer/... → analyze`. Never reorder.
## Verify (in this order)
```bash
ruff check src tests
ruff format src tests # line-length 100, E501 ignored
mypy src/otko/core src/otko/services
pytest -m "not slow" # CI gate: lint → this, on 3.10/3.11/3.12 × ubuntu/windows/macos
```
Focused runs: `pytest tests/unit` (pure logic, ms), `pytest tests/gui -k <name>` (pytest-qt, needs display), `pytest tests/integration -k <name>` (real OpenSeesPy runs). Single test: `pytest tests/unit/test_project.py::test_name -q`. Markers: `gui`, `slow`. Linux GUI tests need `xvfb-run -a pytest ...` plus system Qt libs (see `ci.yml` apt list).
Notes: `tests/conftest.py` auto-`ops.wipe()`s the OpenSees domain between tests (lazy import so core tests stay Qt/OpenSees-free). Coverage omits `views/`. Commit style: Conventional Commits (`feat:`, `fix:`, ...). `pre-commit install` runs ruff + mypy (mypy hook scoped to `core|services|viewmodels`).
## Examples & persistence
- `examples/*.py` are source of truth; `examples/*.osmodel` are generated artifacts (checked in). Never hand-edit `.osmodel` — change the script and regen: `python examples/cantilever.py` (each script saves, reloads, asserts clean round-trip).
- Projects persist as single Pydantic-validated JSON `.osmodel` (diffable); analysis output goes to `*.osresults.h5` (HDF5, one group per case).
- Quick smoke: open `examples/cantilever.osmodel` → run `Tip-Load` → M3 peaks 50 kN·m at fixed end.
