• Fixed permanent IBD stall caused by stale chainstore checksum and a non-durable accumulator file: nodes that crossed the assume-utreexo checkpoint no longer brick on dirty shutdown and re-ban every honest utreexo peer (jvsena42/Floresta-mandacaru#16, #74).
• Refreshed the bundled assume-utreexo snapshot to a more recent height, shortening IBD on fresh installs.
