Box_tilC encodes the tile offset table with offset and size fields whose widths (32/40/48/64 and 0/24/32/64) are configured in the box flags. writevec() blindly stored the low N bytes of a uint64_t, so an offset past the configured field width was silently truncated, leaving the written offset table pointing into nonsense in the iloc data. At decode time the truncated offset would point at random bytes, which the generic-compression decompressor (zlib/brotli) then reported as "invalid stored block lengths" - reproducible by zooming to the highest pyramid layer of a tili image larger than the offset field can address. set_tild_tile_range now returns an Error when the value does not fit, and write_offset_table re-checks each row as a defense-in-depth before emitting the table. The existing add_image_tile call site propagates the new error. Existing files written with truncated offsets remain corrupt on disk; this only prevents producing such files going forward.
