experiment:
  name: VibeGeometry
  status: runtime_csg_shell
  phase: vg_csg_focus
  premise: >
    VibeGeometry is now the thin repository shell around the `vg-csg` Rust
    work surface. Historical scene-generation research machinery has been
    removed from the live tree.

mission:
  primary: >
    Build a fast runtime CSG machine capable of lowering domain/tree intent into
    an LOD-aware CSG hierarchy and emitting triangle/collider output for a
    camera or frustum query in milliseconds.
  work_surface: crates/vg_csg

hard_boundaries:
  - Do not rebuild the historical scene-generation pipeline in this repo.
  - Put implementation in `crates/vg_csg` unless a task proves a root-level
    surface is necessary.
  - Preserve exact parity only for public RealtimeCSG-style behavior the crate
    explicitly claims to mirror.
  - Runtime evidence must include selected-cut, dirty rebuild, emitted geometry,
    and timing data where performance claims matter.

live_architecture:
  pipeline:
    - Domain or tree intent enters `vg-csg`.
    - The runtime chooses an LOD-aware selected cut for the requested view,
      budget, dirty state, or output scope.
    - The selected cut lowers to CSG/brush operations.
    - The crate emits triangle and collider output plus receipt/timing evidence.
  root:
    - Minimal Cargo workspace.
    - `crates/vg_csg` git submodule.
    - Minimal README/AGENTS/state pointers.

current_status:
  summary: >
    Root-level scene-generation surfaces have been deleted. `vg-csg` is the live
    work surface for future domain-tree, LOD CSG, selected-cut, and triangle
    emission work.
  next_action: >
    Continue inside `crates/vg_csg`: define the first LOD/query contract for
    selected CSG output rather than adding new root scaffolding.
