__[0-9A-F]{10}_TAG

Re-entrancy guard variable-name pattern in the obfuscator.io first-stage blobs (e.g. __EE9863E13F_TAG). Together with the string-array function name it defines the 5 build clusters (A=__EE9863E13F_TAG, B=__7D0A53D40B_TAG, C=__38CC632841_TAG, D=__70FE9F7AB6_TAG, E=__4C6BA78C7C_TAG). Members in the same cluster share an obfuscator seed, explaining the byte-identical blob reuse (Amazon Inspector + SafeDep). Hunt as a code/regex fingerprint.
