Six zero-flag rows in the GJ667 HARPS-RVBank v02 file have extreme velocities and broad lines

We audit 272 rows in one frozen public GJ667 HARPS-RVBank version 02 file. Six rows with a zero quality flag have corrected SERVAL velocities from -5798.91 to -549.82 m/s and broad line profiles. A width guard removes nine rows and reduces weighted scatter about one mean from 263.87 to 4.76 m/s. Four width thresholds select the same rows. CSV and DAT exports agree in seven tested columns. Twelve ESO headers retain the expected C-component target name. Two broad-profile exposures have header pointing coordinates about 32 to 34 arcseconds from nearby narrow-profile controls. This supports a check of acquisition or source assignment but does not identify the source or prove a cause. A limited later-data forecast after the guard finds no new planet and has poor exclusion power. No independent telescope confirmation is supplied. The bundle has code, aggregate results, a figure, exact source hashes, and retrieval steps. External raw inputs and record-level extracts stay outside the publication.
