Source audit
Definitions, theorems, assumptions, proof route, and exact anchors.

Embedded geometry: second order
Stable source-facing chapter environment inside the shared Samplinglib reader.
scaffoldsource mapFull source closure not claimed
Planned route
Source → theorem map → reusable Lean nodes
Upstream alignment
Search Mathlib and local geometry interfaces; adapt only real statement or convention differences.
Frontier Cells
Only genuinely missing mathematical edges become theorem-sized tasks.
Graph placement
Dependencies, consumers, cross-library bridges, and reusable shared interfaces.
