Declarations come from the modules' own manifests and the list of predefined keys from the indexer's, whatever the
switch says; compare keeps only the pull request rows; hand-back is answered as gone; a switch that still names the
controller is read as the indexer and said gone. The read-only mirrors, mirrorDeclarations/mirrorList and the value
and list comparisons are deleted with their test cases (two table tests lose their mirror rows, one block of the
newest-list test goes; two table rows added).
