The block slicer used the block number as a character offset (loadfile_tlv[i * 2:(i + 240) * 2]), so every LOAD block after the first was a 1-byte-shifted copy of the previous one - the cap header repeated every 239 bytes on the wire. A live install accepted three blocks, failed block 4 with SW 6400, then 6985, and INSTALL [for install] answered 6A88. The same slicing was inherited by the SCP81 helper from the SCP80 path, so multi-block caps could not install there either; both are fixed. Tests: blocks are consecutive and reassemble the C4 TLV byte-for-byte (200 python); findings updated; service worker v149.
