The lane that did this was killed before it could commit; the tree it left is green and is preserved here rather than lost. Root package 51.5% at the start of the day, 93.3% at its last checkpoint, 98.6% now, with cert, fhe, types and cmd/plugin all passing. Includes the fault-injection suite it was building when it stopped: a node that cannot read its state does not start, and one that cannot enumerate its registry does not either. Not reviewed by me beyond build, vet, gofmt and the full suite under -count=1. The lane's own report is owed and did not arrive, so its mutation count and its verdict on the mpcvm/fhe duplication are unrecorded.
