A from-genesis sync of the patches-only build reached the first real anchor
(13,014,000, certificate index 0) and was rejected there: PqAnchorSealsRule
says index 0 is unbound, though the registry the node itself bound contains
key 0 and production validates the same block. Two paths over one registry
that disagree. Fix (align the index->address mapping in 0003 with production
source) needs a dedicated binary session with a negative control. Written
honestly; RUN-A-NODE already flags the build as a follower until a full
import proof. Trying the proof for real found the missing link in one evening.
