Read the equation
Counts the bit positions where query signature q differs from stored signature s_i. It is exact for the supplied bit vectors; repeatable retrieval also requires the same encoder, stored corpus, query and tie policy.
Terms & definitions
The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.
How it works
Read d_i as the quantity being defined or updated by this relation.
Combines binary values with exclusive OR in the stated bit-level expression.
Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.
Assumptions & limits
Conditions
Formula transcribed from a historical July/August 2026 dossier; no current fleet process was executed.
Source recovery establishes that the expression appears in this record. Its mathematical validity, implementation behavior, and interpretation must be assessed separately. See the linked source and research notes for the checks available for this version.
Original context
Exact original notation
d_i = popcount(q XOR s_i)
