resetThresholds(sessionID) clears crossed and maxCrossed but leaves writerFailures untouched. A session entering a fresh checkpoint threshold cycle after rebuild could inherit stale failure counts, hitting the retry cap prematurely. Add writerFailures.delete(sessionID) so all per-session checkpoint threshold state resets together. Add test that records failures, calls resetThresholds, then verifies the next cycle starts with a fresh failure count. Closes: XiaomiMiMo#734
