* Identify ICT contacts by the TestPoint ICT variant ict= now pairs with a dedicated ICT TestPoint variant whose footprint carries a 3 mm courtyard — KiCad's native courtyard DRC enforces the interposer pogo pitch on the board itself, with no generated rules. IPC extraction requires the TestPoint_ICT footprint alongside the Ict characteristic. * Let ict= imply the ICT footprint Existing boards set ict= on ordinary pad variants; erroring would break their builds. The role now upgrades the footprint to TestPoint_ICT on any variant, so those boards pick up the courtyard on their next layout sync, and only an ICT variant without a role is an error. Also formats the zen per pcb fmt. * Tighten the changelog entry * Reject ict= on Keystone test points The upgrade path would swap in the ICT footprint while the Keystone branch keeps its commercial MPN and BOM/CPL presence; the combination is incoherent, so it errors. * Prune low-value comments The ict= rationale lives once, in the config help.
