Post-2026-05-26 unclean node2 reboot left redis-v2-2's incremental AOF
truncated at offset 84799139. With aof-load-corrupt-tail-max-size at its
default 0, redis refuses to load any corruption and crashloops. Setting
1024 lets it truncate the corrupted tail and continue, which is the
right call for a non-source-of-truth cache fronted by sentinel.
