harden: regenerate user_project_wrapper via cf harden (cf_wrapper_v5)
CI / rtl-lint (push) Has been cancelled
Re-hardened wrapper with chipfoundry-cli (LibreLane) per contest item #3.
Macro ldpc_decoder_top unchanged (Run 6 / antenna_iterative golden) —
wrapper config has SYNTH_ELABORATE_ONLY=true and reuses macro as a
hardened black box.
Results vs wrapper_v4 baseline:
setup violations: 3402 → 0
hold violations: 13006 → 0
antenna nets: 1179 → 23
Magic + KLayout DRC: clean
power-grid: clean
LVS pin-match: 208 (cosmetic, vssd2 + constant-tied outputs)
Verification:
cf precheck: 17/19 pass (FEOL SIGSEGV + LVS pin-match
pre-existing accepted)
cf verify ldpc_basic --sim gl: PASS (GPIO=0xAB, decode success)
GDS/DEF/SPEF kept local for cf push.
