# Ariadne — the cvcGL UI & scene DSL (Scoping Spec v0.14, for iteration)

Status: **draft for discussion, no code committed.** Grounded in a full survey of
Status: **SUBSTANTIALLY LANDED (2026-10). Verify any feature in the code, not this spec — it lags the tree.** Implemented: the `state_exec` engine, widget/layout model, reactive + action lanes, composition/URI, the scene-graph core, the streamed-source zero-copy contract + clipping, Unicode, and the backend-core split + AppRuntime refactor. Also landed despite still reading as open/planned in sections below — `input_text`/`input_int` (§3.5/§6, `loader.cpp`, #636), `RenderView`/`VisibilityMask` (§9.5, `src/cvcGL/RenderView.cpp`), the light scene node (§9.1, `LightNode.cpp`), clipboard (§17.8, `Clipboard*.{cpp,mm}`), `state_exec` async-scheduler parity (§7.1/§7.7, `receive_message`/`sleep`/`yield_frame`), JSON-Schema validator integration (§15), the **tvision** terminal backend (§16.4), the **EGL golden-image harness** (§16.6), and geometry LOD. **Genuinely remaining (verify per-item):** TF editor + `data()`-channel authoring (§10), `state_exec` program modularity `(include/load "uri")` (§19), the full YAML-free s-expr `.ari` *document* dialect (§18), the formal draft-2020-12 JSON Schema + `ari validate` CLI (§15), HTTP response-cache LRU (§13.9), pycvc URI handlers (§14.2). The version history and per-section status below are kept for provenance but are **not** authoritative; see `ARIADNE_CONFERENCE_ROADMAP.md` §13.

Grounded in a full survey of
the ImGui infrastructure (`ImGuiOverlay`, `ImGuiBinding`, `SceneRenderer`,
`RenderView`, `Settings`, `StageLighting`), all 14 cvcGL examples, and the
`cvc::state_exec` subsystem — all on `origin/master` (`4fb4e1198`). **Ariadne** is a

# Visibility, Culling & LOD — Design & Roadmap

**Module:** `cvc::vis` (headless, in `inc/cvc/vis/` + `src/cvc/vis/`) plus a thin VTK-facing adapter in `cvcGL`.
**Status:** design, not yet implemented.
**Status:** **LANDED (PR #249+).** The geometry/scene LOD described here is implemented — `inc/cvc/lod/select.h` (rung selection + hysteresis + the budget `solve()`), `lod/pyramid.h`, `cvc/geometry/simplify.h` (native QEM), `lod/tiles.h` (partition + tiled pyramids), `lod/store.h` (HDF5 `scene.cvch5`), the cvcGL `LodGraphicsNode`, and `cvc::vis` culling. The design-notes framing below predates the implementation — read it as rationale, not a TODO. **Still open:** physics LOD (none yet) and the runtime residency/paging driver (HLOD §4.2) — tracked in `ARIADNE_CONFERENCE_ROADMAP.md` §5h (H2/H3).
**Provenance markers used throughout:** **[M]** measured on the target machine (Release, 32-core CUDA box, GTX 1650, 1280×800, vsync **off**), **[D]** derived arithmetically from measured values, **[E]** estimated.
