Real, complete verification logic -- not yet wired to any write path. homeblocks_sig_check(dev, sig_start_fblock, out_sig) reads the 4 consecutive 1KB blkio forth-blocks the 4KB header spans, verifies magic -> version -> CRC-64 in order, returns HOMEBLOCKS_SIG_OK/_BLANK/ _BAD_VERSION/_BAD_CRC/_READ_ERROR. Reuses block_subsystem.c's existing CRC-64/ISO (compute_crc64, previously static/file-local, now exposed via block_subsystem.h) rather than a second CRC implementation -- same algorithm already proven via per-block checksums. Takes the header's starting block as a plain parameter rather than resolving it internally: verifies a signature given a location, finding that location (GPT-partition-relative) stays the caller's job. Verified against the actual shipped code, not a reimplementation: a standalone host test links the real homeblocks_sig.c against a fake in-memory blkio_dev and exercises all four outcomes -- blank media, a correctly-minted header (round-trips drive_uuid/minted_time_ns), a flipped CRC, an unrecognized version. All four pass. A full QEMU-hotplug live test isn't proportionate yet since nothing calls this function from the live kernel path -- wiring it into the attach path is the next punch-list item. Clean zero-warning compile and clean boot on all three architectures confirms no build/link regression from exposing compute_crc64 and adding the new source file to every kernel build.
