Description
Tool for creating proxy geometry for square and planar shapes (walls in photogrammetry, pseudo-stratigraphy forms in geophysics from point clouds or rasters). Uses a 7-point measurement system to generate box meshes with configurable pivot. Each point is formalized as an ExtractorNode — every measurement is a traceable paradata claim about the proxy’s geometry. A CombinerNode aggregates the seven extractors into the proxy’s final geometry assertion, wired to the active Stratigraphic Unit through a canonical paradata chain (US —has_property—> PropertyNode(‘Proxy Geometry’) —has_data_provenance—> Combiner —combines—> Extractor —extracted_from—> Document). The whole chain is wrapped in a per-US ParadataNodeGroup (_PD) that inherits the US’s is_in_activity edge so both sit inside the right Activity yEd group at save time. For every run the Step-1 anchor Document is cloned into a fresh instance (same display name, new UUID, copied three-axis classification) so extractors never attach to a Document already wrapped in another PD group. Two-step UI: Step 1 pick/establish the anchor Document (from selected mesh or via search/create), Step 2 record the 7 points (Propagate toggle auto-fills document + extractor id on Record, gap-aware). A chain summary box narrates the paradata chain before Create. The panel reuses the shared Add-US dialog for all US creation (see DP-55). Constraint: because the tool writes to the GraphML file on disk, the .graphml must NOT be held open by yEd — the tool runs a write-lock pre-flight before any mutation. Save-after-create is on by default, so the chain lands on disk as soon as Create finishes.

Notes
Related to DP-33 (Stratigraphy Manager+), DP-50 (Surface Areale — sibling RM→proxy pipeline), DP-55 (US Creation Workflow Unification — powers the + Add US button in this panel), DP-07 (Document Node three-axis — the anchor carries role/content_nature/geometry). Remaining 1.5 work: field-test pass, then drop the experimental_features gate.
