The official Complete Index badge requires unlocking all ASMRS. A Jul 30 recording showed 56 Index slots, but use your live Found total and missing silhouettes because the collection can change.
Complete Index is the clearest collection finish line in Unbox ASMR. Roblox's official badge description says it is earned by unlocking all of the ASMRS. The live Index is therefore more important than any fan-made list because it shows the current slots and your own Found progress.
A Jul 30 collection recording displayed 56 slots and progress states such as 37/56, 38/56, 42/56 and 43/56 Found. That establishes what one build looked like, not a permanent total. New crates or updates can expand or reorganize the Index.
The practical method is to track missing silhouettes, the crates you have actually opened, and each newly discovered name. The partial toy reference helps identify readable entries, but it deliberately does not pretend to list all 56. Unknown drop rates also mean a guaranteed completion-time estimate would be misleading.
