Documented options are review inputs, not universal mandates.\nApplicability questions\n\nFor source statement 1 at 10 CFR 73.46(i)(2) (eCFR anchor p-73.46(i)(2)), which observable configuration, record, or test can confirm applicability here?\nFor source statement 2 at 10 CFR 73.46(i)(1) (eCFR anchor p-73.46(i)(1)), which observable configuration, record, or test can confirm applicability here?\nWhich owner can attest to the recorded state of access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths, including exceptions?\nWhat baseline for identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel must accompany the source-specific observation?\nWhich success, stop, and escalation criteria are written before testing begins?\n\nDSE recommendation:\nDSE recommends using the cited source as the evidence anchor for this decision. Start with applicability, then compare the observed state with the cited source. Record the source location, examined part of access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths, observed and expected states, owner, and reason for deviation.\nIf the review warrants change, use a bounded implementation with prerequisites, test population, monitoring, abort criteria, and a rehearsed reversal. Sequence checks for identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel and sanitize protected material before retention.\nVerification and evidence\nA reviewer should be able to retrace the decision from 10 CFR 73.46(i)(2) (eCFR anchor p-73.46(i)(2)); 10 CFR 73.46(i)(1) (eCFR anchor p-73.46(i)(1)) through asset and firmware inventories, configuration exports, event tests, inspections, alarm response records, and maintenance findings. Record what was collected, where, when, by whom, and which system or role it represents.\nRecord the decision even when no change is made, including uncertainty and the next trigger. Use safe testing conditions for disruptive work, preserve rollback proof, and revisit the conclusion after relevant platform, dependency, vendor, or ownership changes.\nOfficial references\n\n10 CFR 73.46 – Fixed site physical protection systems — U.S. Nuclear Regulatory Commission via eCFR",
