Jan 1, 20262026-01 monthly summary: Focused on stabilizing metrics for TimerMessageStore in apache/rocketmq with no new user-facing features. Primary action was a critical bug fix: revert the metric calculation optimization for the time wheel to restore the prior working behavior and fix incorrect metrics. This maintained telemetry integrity and reduced production risk. Commit 4aa6cdd99ec25da020d7ffb51883184b46292d52 documents the revert and its rationale, aligning with Issue #10019.
