\b does not fire between a digit and '_' because '_' is \w in RE2. The pattern \bpsu?\s*([0-9]+)\b never matched PSU1_POWER_IN style sensors, so parsePSUSDR (and PSUSlotsFromSDR / samplePSUPower) returned empty results for MSI servers — causing all power graphs to fall back to DCMI which reports ~half actual draw. Added an explicit underscore-terminated pattern first in the list and tests covering the MSI format. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
