SelectionState now holds view, gesture, input, menu and orbit sub-structs; all 450 access sites updated mechanically with no behavior change. Deletes three write-only dead fields (box_last, box_last_crossing, poly_last_crossing). Hand-rolled clears in commands and dim_viewport route through the new clear methods; bench fixture updated. Full suite: 1976 passed / 0 failed / 25 ignored.
An XLINE or RAY projects to saturated i32 corners; their difference
overflowed and panicked the debug build on every capture.

- Add \PyramidLevelInfo\, \PyramidManifest\, \compute_pyramid_manifest\, \compute_tile_bounds\, and \point_to_tile\ in \ ision.rs\
- Expose DeepZoom pyramid manifest resource at \cad://session/{session_id}/pyramid/manifest.json\
- Support on-demand and cached pyramidal tile resources at \cad://session/{session_id}/tile/{level}/{x}/{y}.png\ and \.json\
- Add \ ile: { level, x, y }\ and \pyramid_manifest: boolean\ to \ocs_capture\ with regional camera framing
- Enable LLM agents to inspect dense CAD drawings via multiscale resolution levels without exceeding context/tile token budgets
- Add unit tests for pyramid tiling math, manifest generation, resource listing/reading, and structured metadata formatting
- Standardize spatial metadata under \_spatial\ with \CAD_WCS\ CRS, document units, forward/inverse affine matrices (\pixel_to_world_matrix\, \world_to_pixel_matrix\), camera projection, and world bounding bounds
- Implement visual differential engine (\compute_visual_diff\) detecting pixel-level changes between viewport frames
- Map dirty pixel bounding box directly to CAD world coordinates (\dirty_world_bounds\) using the spatial transform
- Add \diff\, \diff_mode\ ('highlight' | 'crop' | 'metadata_only'), and \
eset_diff_baseline\ parameters to \ocs_capture\
- Support high-efficiency dirty region cropping to drastically minimize vision token and bandwidth consumption
- Add unit tests for spatial projection, diff computation, tool schema, and structured metadata formatting
- Add Set-of-Marks (SoM) visual grounding (src/app/control/vision.rs):
* Render high-contrast numbered badges on entity visual centroids in viewport captures
* Project 3D entity bounds to 2D image coordinates with priority ranking (selected/size)
* Return bidirectional grounding manifest (annotations / visible_entities) in capture and ocs_capture payloads mapping each badge to entity handle, layer, type, and world center
- Add regional viewport framing (src/app/control/mod.rs, src/mcp.rs):
* Support view: region and bounds: [min_x, min_y, max_x, max_y] in capture and ocs_capture
* Enable programmatic zoom and high-resolution inspection of specific rooms or local geometry
- Add 2-point raster image calibration (src/app/control/actions.rs, src/mcp_ops.rs):
* Extend embed_image with optional source_points (pixel coords) and target_points (CAD coords)
* Automatically calculate scale, world dimensions, and insertion origin at
* Add unit test embed_image_calibrates_from_source_and_target_points
