The channel membership of the two certified mechanism sentinels: the 16 C>A channels carrying the oxoG reading and the 16 C>T channels carrying the FFPE deamination reading, exactly as the certified channel helpers derive them from the SBS96 registry. This is the channel side of the sentries surface – which specific channels a per-sample sentinel share counts.
Value
An `MsQcMechanismChannels` data.frame of 32 rows in SBS96 registry order, columns in the frozen order `label`, `mechanism` ("oxoG" / "ffpe"), `citation`.
