Suggested next actions

  • Review library-only metal1 pin offgrid markers as waiver / abstract candidates
  • Escalate top-level TopMetal2 / TopVia2 antenna markers to signoff maintainers
  • Escalate refined upper-metal Magic obstruction overlaps to signoff maintainers
  • Review residual bbox and lower-metal Magic families after v11 geometry pairing

Request

Please review whether the library-only off-grid pin markers and the remaining top-level antenna hotspots should be treated as waiver / library / PDK signoff artifacts. Raw Magic feedback is now captured, clustered, geometry-paired, mapped into final-view regions, narrowed to bounded candidate ownership zones, then to candidate instance refs, then into bounded side/envelope classes, and now into bounded layer-role conflict classes, so the remaining Magic path is a targeted review / blame-refinement problem rather than another blind replay.
