A page slug segment starting with a dot (a .claude project) staged a file
gbrain's import walker prunes, so the batch was refused on every run.
Leading dots become "dot-" per segment, and slugs recorded in state under
the old name map through the same function so no page is duplicated.
A DNS or connection failure (ENOTFOUND, EAI_AGAIN, ECONNREFUSED, ...) no
longer classifies as broken-db, which routed users to move a working
config aside. The new db-unreachable status carries the reason
"database host unreachable (<code> <host>); your gbrain config is
unchanged. Fix: check network or VPN, then re-run /sync-gbrain.", skips
local sync stages with that reason, and counts as usable for
gstack-gbrain-detect --is-ok like timeout.
