Number every PG-DRC code change in the order data flows from the user-facing Tcl flag down to the FlexGC checks, so a reader can grep for [PG-DRC #1] .. [PG-DRC The-OpenROAD-Project#11] and walk the chain end to end: #1 TritonRoute.tcl -- parse -check_pg_nets The-OpenROAD-Project#2 TritonRoute.i -- SWIG bridge The-OpenROAD-Project#3 TritonRoute.h -- public API param The-OpenROAD-Project#4 TritonRoute.cpp -- write router_cfg_->CHECK_PG_NETS The-OpenROAD-Project#5 global.h -- RouterConfiguration field The-OpenROAD-Project#6 serialization.h -- distributed-worker serialization The-OpenROAD-Project#7 frRegionQuery.cpp -- feed PG snets to drObjs rtree The-OpenROAD-Project#8 FlexGC_init.cpp -- skip PG in fixed-obstacle pass The-OpenROAD-Project#9 FlexGC_cut.cpp -- gate via-table supply-skip The-OpenROAD-Project#10 drc_test_pg.tcl -- end-to-end smoke regression The-OpenROAD-Project#11 CMakeLists.txt / BUILD -- register test in both build systems Also document why FlexGCWorker::Impl::checkCutSpacing_spc() is deliberately left alone: that skip honors LEF SAMENETPGONLY and must keep exempting same-PG-net cuts even when PG DRC is on.

…cfg field
Previous version stashed CHECK_PG_NETS in RouterConfiguration so every
downstream stage could read it via router_cfg_. That made the flag a
hidden global: it lived for the lifetime of the router, would persist
across calls, and forced a serialization entry for distributed
workers. Refactor to plumb the bool as an explicit parameter end to
end so PG checking happens only when, and exactly where, the user
asks for it.
- Drop RouterConfiguration::CHECK_PG_NETS and its serialize line.
- frRegionQuery::initDRObj gains an include_pg_nets bool (default
false). All routing/repair callers keep the default; only
TritonRoute::checkDRC passes true when -check_pg_nets is set.
- FlexGCWorker gets setCheckPgNets(bool) + Impl::checkPgNets_;
FlexGC_init.cpp / FlexGC_cut.cpp read the worker member instead
of router_cfg_.
- TritonRoute::getDRCMarkers takes the bool and forwards it to
each FlexGCWorker before init.
- TritonRoute::checkDRC body re-runs initDRObj(true) only when the
flag is on (idempotent rebuild) and forwards the bool to
getDRCMarkers; default check_drc and the routing flow are
bit-identical to before.
Renumber [PG-DRC #N] markers to follow the new linear chain (#1..The-OpenROAD-Project#10):
#1 Tcl flag parse
The-OpenROAD-Project#2 SWIG bridge
The-OpenROAD-Project#3 TritonRoute::checkDRC declaration
The-OpenROAD-Project#4 TritonRoute::checkDRC body -> initDRObj(true)
The-OpenROAD-Project#5 frRegionQuery::Impl::initDRObj feeds PG to drObjs
The-OpenROAD-Project#6 TritonRoute::getDRCMarkers + FlexGCWorker::setCheckPgNets / member
The-OpenROAD-Project#7 FlexGCWorker::Impl::initDesign obstacle-pass skip
The-OpenROAD-Project#8 FlexGCWorker::Impl::checkMetalWidthViaTable supply-skip gate
The-OpenROAD-Project#9 drc_test_pg.tcl smoke regression
The-OpenROAD-Project#10 CMakeLists.txt / BUILD registration

…inventory User asked for a per-PG-net debug print at the The-OpenROAD-Project#9 supply-skip gate in FlexGCWorker::Impl::checkMetalWidthViaTable (FlexGC_cut.cpp). Add it. Also add a once-per-worker [PG-DRC INV] dump at the end of FlexGCWorker::Impl::init that classifies every gcNet by owner type and flags any signal frNet that has routed polygons. Under strict ingestion (The-OpenROAD-Project#7) a signal gcNet should be pure pins -- only fixed polygons. If a signal frNet has a routed polygon set, the inventory prints a [PG-DRC INV] LEAK line naming the net, which directly identifies how signal-net routed wires reached FlexGC despite the The-OpenROAD-Project#7 strict gate. Why this matters: user's run shows marker srcs with two signal-net frNets (sigType=SIGNAL), which should not happen because spacing checks early-return when both rects are fixed. The leak detector will tell us whether signal frNets have any routed polygons (which means drObjs got contaminated upstream) or not (which means the marker's "non-fixed" rect comes from a different source we haven't considered yet).
