An unreadable, unparsable or unrecognised contributions file was read as "no consumer asks", and the
reconcile pass then removed every consumer it had applied. On 2026-10-04 one such read made the
postgres provider drop every database on the control node. Such a pass now applies and removes
nothing and says why, once; only a file read with a given list withdraws a consumer, and every
removal is logged before it is made.
