The characterization thresholds in template.tcl were incorrect:
delay_inp/out: 0.35 → 0.5 (50% VDD crossing, industry standard)
slew_lower: 0.2 → 0.1 (10%)
slew_upper: 0.5 → 0.9 (90%)

Regenerated .lib files for all 4 variants using Liberate 23.1 (41 cells, 0 failures each).

The characterization thresholds in template.tcl were incorrect:

Regenerated .lib files for all 4 variants using Liberate 23.1
(41 cells, 0 failures each). For 3F variants, netlists were generated
directly from CDL — the probe_fake_gds BPR connectivity prevents
valid LVS/PEX extraction.
