source410: link campaign - entire engine compiles (152/152), first true link,
52-symbol unresolved ledger
build410.sh: merged-engine mass compile + BT TUs + tlib + authentic tlink32.
Engine closure fixes: boxtree/set/l4gauge/filestrm back-dates, lamp<->gaugrend
cycle broken (1995 form), APP.HPP Shutdown default, NetNub include path, DPL
vpx shim, SOS 32-bit lib arbitration (SOSDBXC/SOSMBXC; SOSMW*=16-bit), WATTCP
excluded (16-bit NetNub TSR side). UNRESOLVED-LEDGER.txt = the measured gap to
a linking BTL4OPT.EXE.
