T378983: Add Link recommendation are not being processed by CirrusSearch (November 2024) generated many dangling DB records on Add Link wikis. Those need to be dropped, as the index update were lost due to validation errors (and they are not going to be processed). Otherwise, the refreshing script is never going to return those articles to the task pool (as far as refreshLinkRecommendations is concerned, those articles are in the pool).
The dropping can be done by running fixLinkRecommendationData.php --db-table --verbose --force. This can be only done after the update pipeline is back up (tracked in T378983).
Acceptance Criteria
The number of dangling DB records recorded in Grafana drops to nearly-zero for all wikis.
