OSTI's own machine-readable citation exports, not just display text, independently confirm SAND-91-7095's January 1992 date

The vault's existing note on SAND-91-7095's dating already settled on 1992 as the citation year, treating a "Dec 31 1991" timestamp on one of OSTI.GOV's two duplicate catalog entries (OSTI IDs 5900384 and 10118944) as a likely UTC/EST display artifact rather than a second confirmed date. This note strengthens that call: both entries' own machine-readable citation exports — not just their rendered display text — independently agree. Each entry's BibTeX export reads year = {1992}, month = {01}, and each renders identically in APA format as "Sulsky, D, Chen, Zhen, & Schreyer, H L (1992)." Each entry's own primary date field also displays as "Technical Report · Wed Jan 01 00:00:00 EST 1992." The two duplicate entries cross-reference each other in their "Similar Records" sidebars with a "Tue Dec 31 19:00:00 EST 1991" timestamp — a five-hour offset from each entry's own self-listed "Jan 01 00:00:00 EST 1992," consistent with a UTC-rendering artifact local to that cross-reference widget rather than an independently sourced second date.

Because the agreement now holds across two duplicate database rows' structured export fields, not one record's display quirk, this is stronger evidence for January 1992 than the single-entry observation the prior note recorded. No source with day-level precision (a report cover page, a Sandia release log) has surfaced, so the report is pinned to a month, not a day. This is a quantitative (date) claim, so it needs Tier 1–2 under the sourcing floor; it clears that bar as OSTI's own primary catalog record.
