Primary institutional glossary, Definitions: intentional harmful purpose and unauthorized effects on data/systems. Virus entry csrc.nist.gov/glossary/term/virus distinguishes attachment to host programs/files and self-replication. Direct virus-page fetch timed out; the underlying official NIST SP800-83r1 section2.1, nvlpubs.nist.gov/nistpubs/specialpublications/nist.sp.800-83r1.pdf , independently verifies the host-file replication definition. Only high-level terminology used; no execution, infection or concealment procedure reproduced.

Verified locator: Primary Microsoft technical article explicitly by Gary Sullivan and Stephen Estrop, April2002, updated November2008. YUV Sampling defines4:4:4/4:2:2/4:2:0 and distinct sample grids. Color Space and Chroma Sampling Rate Conversions gives matrix constants and interpolation examples. Introduction uses U/V for Cb/Cr; that naming convention is local to this guide.

Primary first-person academic biography. Paragraphs1–2 verify research on non-interactive zero-knowledge proofs, Harvard graduation in1997, MIT doctorate, IBM Zurich work, Virginia appointment in2007 and Northeastern move in2016. Name-case paragraph explicitly permits conventional capitalization.

NIST SP800-86, August2006, DOI10.6028/NIST.SP.800-86; first author Karen Kent verified on official record csrc.nist.gov/pubs/sp/800/86/final . Section2.1, printedp.2-2, and section3 describe collection, examination, analysis and reporting; section3.1 addresses data integrity and section3.3 interpretation/correlation. Primary institutional guide concerns incident response and troubleshooting, not only criminal proceedings. Clock-offset example is independently stipulated, not an incident reconstructed from the guide.

NIST SP800-88 revision2, September2025, DOI10.6028/NIST.SP.800-88r2; official landing page csrc.nist.gov/pubs/sp/800/88/r2/final . Printed cover byline Ramaswamy Chandramouli and Eric A.Hibbard; landing page omits Hibbard’s middle initial. Sections3.1.1–3.1.3, printedpp.8–11, distinguish clear/purge/destroy by recovery effort and reusability; sections4.5.1–4.5.2, pp.24–25, distinguish outcome verification from adequacy validation. Revision2 supersedes revision1. Concept article contains no device-erasure commands or operational recipe.

PyTorch 2.15, LayerNorm equation and Parameters/eps: epsilon is inside the square root after adding it to coordinate variance; correction=0 uses the divisor equal to the number of normalized coordinates. Parameters are learned per element when elementwise_affine is enabled; eps defaults to $10^{-5}$. Statistics come from the same input in training and evaluation modes. These documented conventions define the stabilized map used in the accompanying independent derivations.
