Issue RCAL-1364 was created on JIRA by Paul Huwe:
While examining the output (detected sources) of source injection, I have observed that stellar completeness drops off about 2 magnitudes brighter than the faint star limit for Roman. Surprisingly, this does not occur for galaxies:

We expect stellar matching (red line) to remain at a high percentage until roughly the AB Mag limit (red dotted-line).
Tests were run on a sample of noise + injected sources, as well as a standard Roman Data Workshop file + injected sources. The magnitudes of injected sources were:
