A failed poll is a gap: First-Principles Data Center Engineering Protocol
Why liquid load bank commissioning data pipelines must record failed Modbus/OPC-UA polls as explicit NaN gaps rather than repeating stale cached values.
1-Second Telemetry, Polling Gaps, Flow Balance Verification, and Delta-T Truth
Independent engineering checklists, mathematical balance equations, and refusal criteria derived from this field volume.
Why liquid load bank commissioning data pipelines must record failed Modbus/OPC-UA polls as explicit NaN gaps rather than repeating stale cached values.
How algorithmic change-point detection (Focus, FLOC, CPOP) identifies candidate slope breaks in 1-second load bank time series without replacing human judgment.
Why merging electrical power meters, liquid flow meters, and RTDs into a commissioning flash report requires a single UTC clock synchronized via PTP or NTP.
The exact bounded engineering sentence a 5-pass liquid load bank flash report can legally support—and why a rack test never certifies whole-hall seasonal redundancy.
