User:FormalDude, a former English Wikipedia mentor, quit from mentorship on December 11, 2023 (diff). However, mentees are still assigned to them (and Special:Log/growthexperiments shows no reassignments happening), see the API or a database query below:
mysql:research@dbstore1005.eqiad.wmnet [enwiki]> select count(*) from growthexperiments_mentor_mentee where gemm_mentor_role='primary' and gemm_mentor_id=30481996; +----------+ | count(*) | +----------+ | 30957 | +----------+ 1 row in set (0.036 sec) mysql:research@dbstore1005.eqiad.wmnet [enwiki]>
To remedy the issue, they tried to re-enroll to be able to quit again, but that did not help. After that, User: Extraordinary Writ (an English Wikipedia administrator) tried to do the same (removal diff), with no luck. To verify, @Urbanecm_WMF tried to take the same action, again unsuccessfully.
Since T288878, we expect quitting mentorship to trigger a mass reassignment of mentees, see https://en.wikipedia.org/wiki/Special:Log/growthexperiments/Stewpot as an example. However, despite trying several times, this does not happen here.
Within this task, we should ensure User:FormalDude's mentees are reassigned, since that is requested by the mentor, see https://en.wikipedia.org/wiki/Wikipedia_talk:Growth_Team_features#Quit_mentorship_but_still_receiving_questions.
