The UP_TO_DATE cache path exited immediately without checking if the cached version still matched the local VERSION. After upgrading (e.g. 0.3.3 → 0.3.4), the cache still said "UP_TO_DATE 0.3.3" and the script never re-checked against remote — so updates were invisible until the 24h cache expired. Now both UP_TO_DATE and UPGRADE_AVAILABLE verify cached version vs local before trusting the cache. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
