Session 14 entry coveringb8c1c780d(first C-7 migration patch + v2 script unfetch-before-fetch fix). Updated durability caveat: 13 most recent commits cover the full arc; commit history table gets the newb8c1c780dand975cda686rows; test count 120 -> 122. Removed a duplicate975cda686row that was added by accident in the previous edit.
