pub const CLEAN_MACROS: &[ShuttleMacro];Expand description
Every signoff-clean macro, with the footprint its own hardened LEF reports.
Dimensions are read from results/final/lef/<macro>.lef of the run whose gds_bytes the
signoff ledger vouches for — the same race-free resolution the submission assembler uses, so
a placement can never be planned against a build that is not the one signed off.
shuttle_wrapper_lock re-derives every number here from those LEFs.
