Document the full wrapper hardening trail:
- Mar 12-13 wrapper_v2/v3/v4 results, mpw_precheck 17/19, and 5/5 GLS pass
- May 7-11 v6-v11 LVS-cosmetic-fix attempts (all seven failed)
The v6-v11 series tried to eliminate the 208 cosmetic LVS pin-match
errors via per-pin conb_1 tieoffs and placement tweaks. All failed
because the errors are a Magic SPICE-extraction limitation (constant-
tied output nets collapse into shared power/ground at extract time),
not a hardening defect. Documented so future sessions don't re-explore
this dead end.
