 - `views/`: PySide6/pyvistaqt only. **No direct `import openseespy`** — go through a service.
 - `views/canvas3d/` (**PyVista/VTK**, default) and `views/canvas_plotly/` (plotly.js in a `QWebEngineView`) are two backends for the same central 3D view. Both satisfy the `CanvasBackend` protocol in `views/canvas_base.py`, share one `SelectionState` owned by `MainWindow`, and are swapped live via **Options → Canvas Backend** (persisted in `QSettings` under `canvas/backend`). `MainWindow._activate_canvas` keeps both widgets in a `QStackedWidget` — never destroy a canvas mid-session (VTK leaves dangling make-current callbacks). Backend-specific gaps are declared by `CanvasCapabilities` (e.g. Plotly has no force-diagram overlay or video export yet); gate UI on `canvas.capabilities`, never on the backend name. `canvas_plotly/trace_builder.py` is pure (no Qt, no pyvista) and unit-tested headless. `PlotlyCanvas` pushes with `Plotly.react`, which resets scene attributes the layout omits: data-only pushes pass `preserveView` so `html.py` carries the live camera and padded axis ranges forward, and the hover/snap marker is restyled only when its visible state changes (a restyle per hover event redraws per mouse move until the stack blows).

 ## Git & Forgejo
 Remote is a self-hosted Forgejo, SSH-only:
 ```bash
 git remote add origin ssh://git@smill-home.ddns.net/smill/otko.git
 ```
 - Web UI / HTTPS clone: `https://smill-home.ddns.net/forgejo/smill/otko.git` (note the `/forgejo` subpath — SSH URLs don't have it).
 - Forgejo SSH runs through the system sshd on **port 22** (`SSH_PORT = 22` in the server's `app.ini`). If the site ever advertises a `:2222` SSH URL again, that config regressed — push/pull with port 22 anyway and flag it.
 - Auth is by SSH key (Forgejo → Settings → SSH Keys). Test: `ssh -T git@smill-home.ddns.net` should answer `Hi there, <user>! ... Forgejo does not provide shell access.`
 - Default branch `main`. Work on short-lived branches (`fix/<topic>`, `docs/<topic>`), open a PR against `main`. Never commit directly to `main` from an agent session.
 - Repo root is `otko/` itself. (On the dev laptop there is also an empty, commit-less parent repo at `Sync/coding/` — ignore it; all git work happens inside `otko/`.)
 ## 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.
 ## Cloned Dependency Source
 Read-only dependency source repositories are available under
 `.slim/clonedeps/repos/` for inspection. Do not edit these clones. The
 structured manifest is `.slim/clonedeps.json`.
 - `.slim/clonedeps/repos/yexiang92__opstool/` — `yexiang92/opstool` at `v1.0.26`; the OpenSeesPy
  pre/post-processor whose PyVista and Plotly visualization settings
  (`opstool/vis/{pyvista,plotly}/plot_utils.py`, `plot_resp_base.py`, `vis_model.py`) are the
  reference for otko's canvas look-and-feel. GPL-3.0, and GPLv3 §13 explicitly permits combining
  it with otko's AGPL-3.0. Any code actually ported from it must keep the opstool copyright notice
  and record that it was modified (GPLv3 §5a/b) — add that entry to `NOTICE` when the port lands.

 merge — no matter how useful the feature.
 ## Dev setup
 ```bash
 python -m venv .venv
-source .venv/bin/activate           # Linux / macOS
+source .venv/bin/activate
-# .venv\Scripts\activate            # Windows
+pip install -e ".[dev]"
 pip install -e ".[gui,dev]"
 pre-commit install
 ```
 `pip install -e ".[gui,dev]"` pulls the Qt/PyVista desktop stack plus the
 dev tools. For a headless checkout (core + services only, no Qt) use
 `pip install -e .` instead. Python 3.10+; on Windows use 3.12+.
 Launch the GUI with:
 ```bash
 python -m otko
 ```
 `pre-commit install` wires ruff + mypy into your local git hooks so
 obvious issues are caught before a commit. Run it once per clone.
 ## Before opening a PR
 Run the verify commands in this order and make sure they are all clean:
 ```bash
 ruff check src tests
-ruff format src tests          # line-length 100, E501 ignored
+ruff format src tests
 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
+pytest -m "not slow"
 ```
 Focused runs are faster while iterating: `pytest tests/unit` (pure logic,
 milliseconds), `pytest tests/gui -k <name>` (pytest-qt, needs a display;
 Linux GUI tests want `xvfb-run -a pytest ...`), and
 `pytest tests/integration -k <name>` (real OpenSeesPy runs). Single test:
 `pytest tests/unit/test_project.py::test_name -q`. Markers: `gui`, `slow`.
 ## Architectural rules (enforced in review)
-OTKO uses a strict one-way **MVVM + service** architecture. Dependencies
+1. `core/` may not import Qt or `openseespy`. Period.
-flow outward-in only:
+2. `services/` may not import Qt.
-
+3. `views/` may not import `openseespy` directly — go through a service.
-```
+4. Public functions and methods need type hints and a docstring.
-views → viewmodels → services → core
+5. New domain entities go through Pydantic validation.
-```
+6. Long-running operations (>50 ms) run off the GUI thread.
 `commands` sits alongside the bridge and owns every model mutation.
 1. `core/` is pure Python — stdlib + numpy + pydantic. It may **not**
   import Qt or `openseespy`. Period.
 2. `services/` may use `core` + `h5py` + `openseespy`, but may **not**
   import Qt.
 3. `views/` (PySide6/pyvistaqt) may **not** import `openseespy` directly —
   go through a service. No business logic in `views`.
 4. `viewmodels/` bridges `core` ↔ Qt (signals, `QUndoStack`).
 5. `commands/` holds the `QUndoCommand` subclasses; all model mutations
   go through `commands`, not ad-hoc edits in `views`.
 6. Public functions and methods need type hints and a docstring.
 7. New domain entities go through Pydantic validation.
 8. Long-running operations (>50 ms) run off the GUI thread (`AnalysisWorker`
   in a `QThread`, cancelled via `isInterruptionRequested()`; results cross
   threads as a lightweight `ResultsHandle` written to HDF5).
 The full package map and the fixed OpenSeesPy command order the runner
 emits live in [`docs/architecture.md`](docs/architecture.md). Never
 reorder the runner's commands.
 ## Branch model
 `main` is the default and integration branch. Work on short-lived topic
 branches cut from `main` — `feat/<topic>`, `fix/<topic>`, or
 `docs/<topic>` — and open a pull request against `main`. Do not commit
 directly to `main` from an agent session. There is no `develop` branch.
 ## Commit style
 Conventional Commits — `feat:`, `fix:`, `refactor:`, `docs:`, `test:`,
-`chore:`, `ci:`. Keep each commit focused; a `feat:` commit should add a
+`chore:`, `ci:`.
 feature, not mix one in with unrelated refactors.
 ## Documentation
 If your change is user-visible, update
 [`docs/QUICK_GUIDE.md`](docs/QUICK_GUIDE.md) and the relevant roadmap or
 ADR entry. Project model files are `.osmodel` (Pydantic-validated JSON);
 regenerate the checked-in `examples/*.osmodel` from their scripts with
 `python examples/<name>.py` rather than hand-editing them.

 - **OpenSees / OpenSeesPy** — the finite-element solver invoked by
  `otko.services.opensees_runner`. OpenSees is copyright The Regents of
  the University of California and is distributed under a BSD-style
  license; the notice is shipped inside the `openseespy` package.
 - **PySide6** — the Qt 6 bindings used by the desktop GUI. PySide6 is
  available under the GNU Lesser General Public License v3 (LGPLv3) or a
  commercial license. OTKO links against it dynamically, which keeps the
  LGPL relinking obligation satisfiable for redistributors.
 - **numpy**, **pydantic**, **h5py**, **pyvista**, **VTK**,

 # OTKO Quick Guide
 A practical, task-first guide to the OTKO desktop GUI. It assumes you
 have already installed the desktop extras and can launch the app:
 ```bash
 pip install -e ".[gui,dev]"
 python -m otko
 ```
 Project files use the `.osmodel` extension — a single, Pydantic-validated
 JSON document that diffs cleanly in Git. Analysis output is written
 separately to `*.osresults.h5`.
 For the layer map and the OpenSeesPy command order, see
 [`architecture.md`](architecture.md). For the feature-by-feature plan, see
 [`roadmap.md`](roadmap.md).
 ## 1. A cantilever walkthrough
 This follows the bundled `examples/cantilever.osmodel` model: a 5 m
 horizontal beam, fixed at the left end, with a tip load. If you would
 rather build it by hand, the steps are below.
 1. **Start a project.** **File → New (3D Frame)**. Pick display units in
   the bottom-right **Units** combo before typing any values.
 2. **Lay out a grid.** **Define → Coordinate System/Grids…** (Ctrl+G).
   Define X lines at 0…5 m (say, every 1 m), Y = 0, Z = 0, and set the
   grid as the active coordinate system. The 3D canvas will draw it as
   reference geometry.
 3. **Add nodes.** **Define → Add Node…** (Ctrl+N), or use the **Draw
   Node** tool and click on grid intersections at (0,0,0) … (5,0,0).
 4. **Define material and section.** **Define → Material Library…**
   (Ctrl+Shift+M) then **Define → Section Library…** (Ctrl+Shift+S). The
   example uses a steel `ElasticSection` named `W12x40`.
 5. **Draw the element.** **Assign/Define → Draw Frame** (F2), then click
   from the first node to the last. Assign the section with
   **Assign → Frame → Section…**.
 6. **Add the support.** Select the node at x = 0 and use
   **Assign → Joint → Restraints…** (Ctrl+R); restrain all six DOF. The
   support icon confirms the fixed end.
 7. **Add the load.** Select the tip node and use **Assign → Joint →
   Point Loads…** (Ctrl+L). The example applies -10 kN in Y. Alternatively
   build the distributed case with **Assign → Frame → Distributed
   Load…**.
 8. **Set up and run the case.** **Analyze → Cases…** (Ctrl+Shift+A) to
   create or review a Static case, then **Analyze → Run…** (F5). The
   bundled file already contains `Tip-Load`, `Uniform-Load`, and a modal
   `Modal-3` case.
 ### Smoke check
 Open `examples/cantilever.osmodel`, run the `Tip-Load` static case, then
 **Display → Show Force Diagram… → M3**. The moment diagram is linear and
 peaks at **50 kN·m at the fixed end**. V2 is a constant -10 kN along the
 span. If you see that, the model, runner, and post-processor are wired up
 correctly.
 ## 2. Running a modal analysis
 1. Open a model that has mass assigned (the bundled cantilever lumps mass
   at every free node so modal works out of the box).
 2. **Analyze → Cases…**, add or select a **Modal** case, and set the
   number of modes `n_modes` (the example uses 3).
 3. **Analyze → Run…** (F5). Results appear in the results/report panel:
   periods, frequencies, and participation factors per mode.
 4. **Display → Animate Mode Shape** to view each mode. Use the mode
   selector and the animation controls, and **Export…** if you want a
   video of the mode shape.
 5. Modal results also feed the response-spectrum case: define a response
   spectrum, then run the SRSS or CQC combination and open
   **Display → Show Response Spectrum**.
 ## 3. Reviewing results and exporting a report or script
 After a run, the results/report panel shows a summary for the active case
 (static reactions and forces, modal periods, and so on). Use the display
 actions to inspect the model visually:
 - **Display → Show Deformed Shape** — with a scale slider.
 - **Display → Show Force Diagram…** — axial (P), shear (V2/V3), moment
  (M2/M3) diagrams.
 - **Display → Show Pushover Curve**, **Show Time-History**, **Show
  Hysteresis** as applicable.
 To hand the analysis to someone else, or to archive exactly what was run,
 export a script:
 - **File → Export OpenSeesPy (.py)…** — writes the full model, and
  optionally a selected analysis case, as a runnable Python script.
 - **File → Export Tcl (.tcl)…** — the same model as classic OpenSees Tcl.
 The export dialog lets you choose "Model only (no analysis case)" or one
 of the configured cases. The generated script follows the runner's fixed
 command order (`wipe → model → node → fix → … → analyze`), so it
 reproduces the analysis outside the GUI.
 ## 4. Changing display units
 Use either control, they are the same setting:
 - The **Units** combo in the bottom-right of the status bar, or
 - **Options → Set Display Units…**
 Changing units updates how lengths, forces, and moments are formatted in
 the UI and plots. It does **not** rescale the underlying model numbers —
 pick the right unit system before you type values, and convert
 deliberately if you switch later. A set of unit labels is available in the
 unit-label tests under `tests/unit/test_unit_labels.py`.
 ## 5. Undo and redo
 Every model mutation goes through the undo stack, so most edits are
 reversible:
 - **Edit → Undo** (Ctrl+Z)
 - **Edit → Redo** (Ctrl+Y / Ctrl+Shift+Z)
 Menu text is dynamic — it names the operation, for example "Undo Add 4
 Nodes". Compound operations such as drawing a frame (node + element) are
 wrapped in a single macro, so one undo removes the whole step. File
 loads, analysis runs, and display-only changes are not model mutations and
 are not undoable.
 ## Where to go next
 - [`architecture.md`](architecture.md) — MVVM layering and command order.
 - [`roadmap.md`](roadmap.md) — what is done and what is planned.
 - `examples/` — 20+ verified models, each generated from a checked-in
  Python script.
 - [`../CONTRIBUTING.md`](../CONTRIBUTING.md) — setup, rules, and verify
  commands.

 > This document plans how to bring that rebuild's good ideas into **this**

 ---
 ## 1. Context
 | | This repo (`~/Sync/otko`) | Rebuild (`~/Sync/otko-development`) |
 |---|---|---|
 | Role | **Working app** — the primary deliverable | Greenfield spec-conformant attempt |
 | VCS | Not a git repo in this checkout | `rebuild` branch, commit `725040e` |
 | License | AGPL-3.0 | MIT (+ `NOTICE`) |
 | Python | 3.10–3.12 | 3.12 only |
 | Project file | `.osmodel` | `.otko` |
 | Scope | Superset: static, modal, **transient, pushover, response-spectrum**, quad/shell-adjacent elements, HDF5 | Narrow v1: static + modal; reports, combinations, self-weight, units display |
 | src LOC | ~37k | ~25k |
 | Gate | deps not installed here; **57 collection errors** locally | `ruff` passes; `mypy`/`pytest` deps missing locally |
 The rebuild is *ahead* on: **reporting/Typst, load combinations, self-weight,
 display-unit conversion, closed-form diagrams, modal mass participation,
 progress/cancel, local-axis editing, viewmodel separation, and quality
 gates**. It is *behind* on everything this repo already ships. Therefore the
 plan is a **selective harvest**, not a merge.
 ## 2. Goal and non-goals
 **Goal.** Adopt the rebuild's good capabilities into this repo, incrementally,
 each phase independently shippable, with the existing app and tests staying
 green.
 **Non-goals.**
 - Do **not** rewrite this repo to the rebuild's architecture (`ProjectStore`,
  frozen `Project`, `CommandFactory`, `services/scene.py`,
  `services/diagram_data.py` substrates).
 - Do **not** replace the runner/export/results surface — this repo's is a
  strict superset.
 - Do **not** change `.osmodel`, the AGPL license, or the Python 3.10–3.12
  support range as part of this plan.
 ## 3. Principles
 1. **Additive, adapt, don't copy.** Port algorithms/patterns; re-type to this
   repo's APIs (`StaticResults`/`ModalResults`, mutable `Project`,
   4-value `UnitSystem`, `element_forces.DiagramData`).
 2. **Protect the working app.** Every phase keeps `pytest -m "not slow"` and
   the GUI smoke tests green. New optional deps stay **lazy** so headless
   installs are unaffected.
 3. **One phase = one branch = one shippable PR**, with tests and a gate.
 4. **Trace every item to a rebuild spec ID** so "is it done?" stays mechanical.
 5. **License hygiene.** MIT→AGPL-3.0 is one-way compatible: preserve the MIT
   copyright/permission notice for ported files (`NOTICE` + per-file header).
   Never copy this repo's AGPL code back into the MIT rebuild.
 6. **Establish version control first.** This checkout has **no `.git`**. Before
   any work, create a repo/branch per `AGENTS.md` (`origin` is the self-hosted
   Forgejo; work on `feat/<topic>`, PR against `main`).
 ## 4. Adoption matrix
 Verdicts: **PORT** (near-verbatim), **ADAPT** (re-type/re-wire), **REIMPL**
 (reimplement against this repo's APIs), **SKIP** (intentional divergence).
 Size: **S** ≈ hours · **M** ≈ a few days · **L** ≈ 1–2+ weeks.

 ### 4.4 Explicitly deferred / skipped
 | Item | Verdict | Why |
 |---|---|---|
 | Polygon-first sections + `services/sections_mesh.py` (opstool GPLv3) | DEFER (Phase 9, conditional) | Schema-breaking redesign; adds GPLv3/runtime deps; not report-critical |
 | Frozen `Project`/entities + `ProjectStore`/`CommandFactory` rewrite | DEFER (not recommended now) | Large coordinated rewrite of 43 commands + all call sites; low user-visible value vs risk |
 | Canvas backend Protocol + `plotly_backend.py` + `services/scene.py` | DEFER (Phase 9) | Requires core + views surgery; plotly pulls QtWebEngine (known teardown SIGSEGV) |
 | `.otko` file suffix / greenfield `Project` schema (PER-001/006) | SKIP | Breaks `.osmodel` corpus and compatibility; do only as an explicit user-approved migration |
 | Rebuild `runner/export.py` | SKIP | This repo's `export.py` is a superset (5 case types, `.py`+`.tcl`) |
 | Rebuild static/modal HDF5 | SKIP | Rebuild has none; this repo's transient HDF5 is already better |
 | Rebuild slim `materials`/`analysis`/`loads` unions | SKIP | Dropping `HystereticSM`, Transient/Pushover/ResponseSpectrum, Path/Imposed patterns would regress shipped features |
 | MIT license / py3.12-only / single-OS CI assertions | SKIP | Intentional differences (AGPL, 3.10–3.12, 3-OS matrix) |
 ## 5. Phases
 ### Phase 0 — Foundations, safety net, quick wins
 **Why first:** makes later phases verifiable and cheap; all items are
 additive and low risk. Also unblocks the mpy gate that currently does nothing.
 - **Prep:** initialise git and a `feat/rebuild-adoption` branch (§3.6).
 - **Q1** Create `src/otko/_const.py` (`__version__`, `OPENSEESPY_VERSION`),
  switch `pyproject.toml` to `dynamic = ["version"]` + `[tool.hatch.version]`,
  and import the pin in `services/export.py` (currently duplicated at
  `export.py:52`). Spec: PKG-032/033, RUN-085.
 - **Q2** Port `tests/unit/test_architecture.py`; adapt `CANVAS = views/canvas3d`
  path and `services/{_emit,_run}.py` paths. Expect it to flag three existing
  offenders — decide per item: `OSS_PICK_DEBUG` env var in
  `views/canvas3d/model_canvas.py:29` (ARC-052), `QUndoStack` outside VMs, and
  the canvas path. Either fix or add a documented, narrow allowlist.
 - **Q3** Split CI: `lint` (+`ruff format --check`), **`type` (mypy scopes)**,
  `test-headless` (`pytest tests/unit tests/services -m "not slow"`),
  `test-gui` (`xvfb-run pytest tests/gui`), `test-integration`
  (`pytest tests/integration -m slow`). Add `pytestmark = pytest.mark.slow` to
  integration modules. Keep the existing 3-OS × 3.10–3.12 matrix and the long
  Linux Qt apt list.
 - **Q4** `tests/conftest.py`: `QT_QPA_PLATFORM=offscreen` default; move
  `ops.wipe()` to teardown (this repo currently wipes before each test).
 - **Q5** Move service-level tests (`runner_translation`, `persistence`,
  `results`, `export`, …) into `tests/services/`; update CI and `AGENTS.md`.
 - **Q6** Add `docs/QUICK_GUIDE.md` + `docs/README.md` (rewrite `.otko` →
  `.osmodel`, rebuild-only APIs → this repo's), update `CONTRIBUTING.md` with
  the 5-layer table + install/run/test commands; port `test_docs.py`.
 - **Q7** Add `NOTICE` crediting MIT `otko-development` for ported files;
  add a per-file header to ported files (`# Ported from otko-development
  (MIT), (c) 2026 OTKO contributors`).
 - **Q8/Q9/Q10** `pyproject.toml`: drop `scipy`/`pandas` from `[gui]`; convert
  mypy to scoped `strict` overrides (core/services/viewmodels); add
  `[tool.coverage.run] fail_under`; port the `test_packaging.py` subset that
  applies (entrypoint, version single-source, line length).
 - **U1/U2/U6** Port `views/formatting.py`; timestamp the console
  (`views/docks/console.py` into the existing dock); add `save_layout`/
  `restore_layout` (`QSettings`) and a `closeEvent` unsaved-changes prompt.
 **Gate:** `ruff check src tests`, `ruff format --check src tests`,
 `mypy src/otko/core src/otko/services src/otko/viewmodels`,
 `pytest -m "not slow"`, arch test, and the new packaging/docs tests pass.
 ### Phase 1 — Cheap, safe services wins
 - **S1** Port `services/solver_session.py` (`SolverSession`, `RealSolverSession`,
  `RecordingSolverSession`). Inject into `OpenSeesRunner` while keeping the
  existing `ops_module=` shim; consolidate the two wipe paths
  (`_emit.py:105` → `session.reset()`). Tests:
  `tests/services/test_solver_session.py`.
 - **S2** In `services/persistence.py::save_project`, call
  `validate_references()` first and refuse to write an invalid model,
  reporting the problem list (PER-022); return the resolved path (PER-021).
 - **S3** Extend `StaticResults` with `time` and add a `ModeParticipation`
  record to `ModalResults` (keep the existing dataclass names — consumers in
  `views/docks/results_panel.py` dispatch on them).
 - **S4** `RUN-053`: return an absent (not zero-filled) force entry when a
  component is missing; guard the static `eleForce` fallback.
 **Gate:** new service tests + existing runner/persistence tests green; runner
 integration suite unchanged.
 ### Phase 2 — Progress & cancellation
 - **S5** Add to `services/qt_workers.py`: `progress(int)`, `cancelled`,
  an `_interruption_requested()` check between steps, and a bounded teardown
  wait. Add `AnalysisRunner.cancel()` (calls `QThread.requestInterruption()`).
  Wire progress callbacks through static (`RUN-054`) and modal (`RUN-063`)
  runs. Replace the indeterminate bar in `views/dialogs/run_analysis.py` with
  a real progress bar + working Cancel (UX-081). Add per-case status to the
  case manager (ANL-050).
 - **S6** Unify modal mass participation: put the rebuild's participation
  math into one service and have **both** modal results and the existing
  response-spectrum path (`services/spectrum.py`) consume it. Add the ANL-013
  no-mass warning.
 **Gate:** cancel leaves no partial handle; progress reaches 100; participation
 sums to 1.0 against a hand-checked example.
 ### Phase 3 — Units display layer + GRAVITY
 - **S7** Port the display machinery from `core/units.py` **as an adapter**:
  keep this repo's 4-value `UnitSystem` and map families
  (`SI_M_N|SI_MM_N → METRIC`, `US_FT_KIP|US_IN_KIP → IMPERIAL`); add
  `GRAVITY`, `display(value, system, quantity, pref)`, `DisplayPrefs`; add
  `ProjectMeta.display` (persisted). Retarget the status-bar/menu unit picker
  so it writes **display prefs**, not the stored `meta.units` (fixes UNT-031).
 - Watch-outs: rebuild uses `StrEnum` (3.11+) — do **not** adopt it (this repo
  targets 3.10). `export.py` currently embeds `meta.units.value`; keep that
  but source labels via the new API.
 **Gate:** switching display units changes every label and leaves
 `project.model_dump()` byte-identical; old 4-system `.osmodel` files still load.
 ### Phase 4 — Closed-form diagrams
 - **S8** Port `core/diagrams.py` near-verbatim (pure numpy, self-contained).
 - **S9** Build a new `services/diagram_data.py` (REIMPL) on top of this repo's
  `StaticResults` + load patterns, reusing `core/diagrams` for interior
  shapes/extrema. Run it **alongside** `services/element_forces.py`, migrate
  `views/canvas3d/diagram_renderer.py` and `views/dock_manager.py` behind a
  flag, then retire the old extractor once the on-screen output matches.
 **Gate:** port `test_diagram_data.py` (end-values, Vz/My plane, axial,
 all-six components, shared data, auto-scale); on-screen diagrams unchanged.
 ### Phase 5 — Reporting pipeline ★ (the headline v1 capability)
 - **S10** Port `services/report/{__init__,csv,figures,typst,pdf}.py`. Add a
  `[reports]` extra (`matplotlib`, `imageio-ffmpeg`; Typst CLI optional, probed
  via `shutil.which`, graceful degradation per RES-046). Expose a "case report"
  action that produces the full set: CSV tables, PNG (≥300 dpi), SVG, a Typst
  document (PDF optional), conditional static/modal sections.
 - Dependencies: **Phase 3** (units) and **Phase 4** (diagrams) must land first;
  reuse **Phase 1** result fields.
 **Gate:** the reference test — cantilever moment **50 kN·m at the fixed end**
 (RES-061) — plus report generation off the GUI thread and preservation of the
 original model file. Port `test_report_{csv,figures,typst,modal}.py` and the
 `test_full_report.py` / `test_report_reference.py` integration tests.
 ### Phase 6 — Local axis (user-editable)
 - **S11** Port `core/geometry/local_axis.py`; add
  `local_axis: LocalAxis` to the frame elements (`ElasticBeamColumn`,
  `ForceBeamColumn`, `DispBeamColumn`, `BeamWithHinges`). Change
  `services/_emit.py` geomTransf to read the explicit axis and dedup by
  `(type, vecxz, roll_deg)` instead of auto-deriving. Update the renderer
  triad (its current `getattr(el, "vecxz")` at `model_renderer.py:727` is dead
  code) and add an editor (property dock / dialog).
 - **Critical migration risk:** a blind default `vecxz=(0,0,1)` is parallel to
  a vertical member's axis and would break existing vertical models. Use a
  **safe default rule** (e.g. derive the default from geometry exactly as the
  runner does today, then only override when the user sets it) so existing
  `.osmodel` files keep loading and producing identical results.
 **Gate:** existing frame/eigen integration tests unchanged; new
 `test_local_axis_parallel_rejected` + `test_geom_transf_dedup_by_combination`.
 ### Phase 7 — Load combinations + self-weight
 - **S12** Port `core/combinations.py` and `commands/combinations.py`; add
  `Project.combinations`; extend `validate_references`; add
  `StaticCase.combination_id` with the XOR invariant (combination **or**
  patterns+factors, ANL-001); materialise scaled loads in the runner
  (LOD-054) without regressing the existing per-pattern factor path.
 - **S13** Reimplement `services/self_weight.py` against this repo's types:
  `w = ρ·A·g` distributed local for frames, equivalent nodal loads for trusses
  (UNT-042/043), a `ConstantTimeSeries` + `PlainLoadPattern`, regeneration that
  replaces the prior pattern (LOD-041), no-density/unresolved reporting
  (LOD-042), and the gravity constant recorded in the description (UNT-045).
  Add a `RegenerateSelfWeightCommand` (undoable).
 - **S14** `ElasticIsotropic` currently is the only material with `rho`
  (`materials/__init__.py:28`); add `rho` to the other self-weight-capable
  materials, or report them as missing density.
 - Depends on **Phase 3** (`GRAVITY`) and **Phase 6** (correct local projection).
 **Gate:** port `test_loads_combinations.py` and `test_self_weight.py` (minus
 the combination assertion until S12 lands); verify superposition matches a
 hand calculation.
 ### Phase 8 — UI/UX adoption (larger, optional but valuable)
 - **U3** `ValidatedDialog` base + migrate dialogs incrementally (unit suffix
  via the Phase 3 API).
 - **U4** Extract `ResultsVM` (per-case handle cache) and `CanvasVM` (selection
  ownership) as supersets of the current state holders so existing call sites
  keep working.
 - **U5** Reimplement overlay **pure helpers** against this repo's
  `deformation`/`element_forces`: ghost undeformed (CAN-062), unit-labelled
  diagram extremes (CAN-082), zero-component hint (CAN-083), and
  pattern-filtered load display (CAN-052/LOD-063). Unit-test them display-free.
 - **U7** Adopt `ThemeManager` + a dark icon set — **verify SVG provenance and
  license first** before copying any icon assets.
 - **U8/U9** Thicken `ProjectViewModel` (move `action_handlers.py` logic into VM
  methods, one command family at a time) and add analysis-case status /
  Simple-vs-Advanced controls.
 - **Q11/Q12** Spec-ID traceability harness and performance probes (only if the
  team commits to the `[AREA-NNN]` convention and a perf budget).
 **Gate:** GUI tests under `xvfb-run`; VM logic unit-tested without a display.
 ### Phase 9 — Deferred, only on explicit decision
 - Polygon-first sections + `sections_mesh` (opstool **GPLv3**, lazy import,
  optional `[sections]` extra; ensure AGPL compatibility and attribution).
 - Frozen `Project`/`ProjectStore`/`CommandFactory` migration.
 - Canvas backend Protocol + plotly backend + `services/scene.py`.
 Revisit only after Phases 0–8 are stable and if the value justifies the blast
 radius documented in the dossiers.

 ```
 **Critical path to the v1 promise (a printable case report):**
 `Phase 3 → Phase 4 → Phase 5`, with `Phase 1` as a cheap prerequisite and
 `Phase 2` interleavable.
 ## 7. Licensing & attribution
 - This repo is **AGPL-3.0**; the rebuild is **MIT**. MIT code may be
  incorporated into an AGPL work — **one-way**. Preserve the MIT notice:
  add a `NOTICE` (Phase 0) and a short provenance header to each ported file.
 - **Never** copy this repo's AGPL code back into the MIT rebuild.
 - `opstool` is **GPLv3** (only relevant to deferred `sections_mesh`); GPLv3 ↔
  AGPLv3 are compatible. Keep it lazy/optional and do not vendor its source.
 - Verify the provenance/license of any copied **icon/SVG assets** before
  adopting the dark icon set (U7).
 ## 8. Risks and mitigations
 | Risk | Mitigation |
 |---|---|
 | Big-bang port destabilises the working app | Strict additive phases; feature flags for diagram/report migration; keep old paths until parity is proven |
 | Freezing/command rewrite stalls progress | Explicitly deferred (Phase 9); combinations/self-weight do **not** require it |
 | Units enum change corrupts stored models | Keep 4-value enum; add a family mapping + `DisplayPrefs`; byte-identical dump test |
 | Local-axis default breaks vertical members | Derive default per-element as today; override only on explicit user set; regression tests on vertical frames |
 | opstool private-API coupling / GPL | Deferred; pin version + thin adapter; lazy import; attribution |
 | Report pipeline pulls GUI deps into headless | Keep `matplotlib`/Typst optional and imported lazily; headless CI must pass without `[reports]` |
 | `StrEnum` / 3.11-only syntax | Target py3.10: avoid `StrEnum`, `zip(strict=)`, etc. |
 | No VCS in this checkout | Initialise git + branch before any code changes |
 | Tests can't run locally (deps missing) | Phase 0 fixes env expectations; run gates in CI |
 ## 9. Tracking
 Adopt the rebuild's `.otko-build/tasks.json` **pattern** (schema, gates,
 `{id, phase, layer, specs, title, tests, status, deps}`), seeded from this
 plan. Each task names the phase, the spec IDs it implements, and its tests
 (the rebuild's `tasks.json` is a working reference). Keep build state out of
 versioned source (`.gitignore` it) or commit it deliberately — team choice.
 ## 10. Recommended first step
 Execute **Phase 0** in one branch. It is almost entirely additive, it turns
 the currently-inert mypy/CI gate into a real one, and it establishes the
 attribution and docs baseline the later ports depend on. Then proceed
 `1 → 2 → 3 → 4 → 5`, pulling Phase 6/7 forward only if self-weight is needed
 before reporting.

 # OTKO — specifications (this repo)
 This folder holds **OTKO's own planning documents**. It is deliberately
 separate from the greenfield rebuild spec set at
 `~/Sync/otko-development/specifications` (docs `00`–`14`), which stays the
 reference for *what a conformant rebuild looks like*. Requirement IDs of
 the form `[AREA-NNN]` cited in this folder refer to that rebuild set.
 ## Why this folder exists
 `~/Sync/otko` (this repo) is the **working, feature-rich app** and is the
 primary deliverable. `~/Sync/otko-development` is a **greenfield rebuild**
 that conforms closely to the rebuild specs but is less capable in several
 areas (transient/pushover/response-spectrum, richer element/material
 coverage, `.osmodel` corpus, HDF5). The goal of the plan below is to
 **harvest the rebuild's good, spec-conformant capabilities into this app
 without breaking what already works** — not to rewrite this app to the
 rebuild's architecture.
 ## Documents
 | # | Document | Purpose |
 |---|---|---|
 | 15 | [15-rebuild-adoption-plan.md](15-rebuild-adoption-plan.md) | Dependency-ordered plan for porting rebuild capabilities into this repo, with adoption matrix, phases, gates, risks and explicit skips. |
 ## Ground rules (summary — see doc 15 §3)
 - **Additive, never replacement.** This repo is a superset of the rebuild
  in the solver/runner/export surface; protect that.
 - **Keep the working app working:** `.osmodel` format, AGPL-3.0 license,
  Python 3.10–3.12 support, existing tests green.
 - **Adapt, don't copy:** re-type ported code to this repo's APIs
  (`StaticResults`/`ModalResults`, mutable `Project`, 4-value `UnitSystem`).
 - **One phase = one branch = independently shippable**, each with its own
  tests and gate.
 - **License hygiene:** the rebuild is MIT, this repo is AGPL-3.0; MIT→AGPL
  is compatible, but ported files need attribution (see doc 15 §7).
