Code Logic & Mataki-Mataki

// 1. Binary Conversion

src = bin(0x) // = "?"

// 2. Extract Fields (Bit Slice)

header = src[0:8] → "00110000" → "?" (?)
filter = src[8:11] → "..." → ?
partition = src[11:14] → "..." → ?

// 3. Determine Partition Rule (Partition ?)

rule = PARTITIONS[?]
// Company Bits: ?, Item Bits: ?

// 4. Extract Company & Item

company = src[14:14] → "..." → ?
itemRef = src[14:14] → "..." → ?
serial = src[14:96] → "..." → ?
