OpenClaw 2026.4.20 Update Fails: Missing Grammy Module Breaks Telegram Runtime

Issue 69837: Update to 2026.4.20 fails because bundled package cannot resolve grammy from Telegram extension.

A CLI tool that snapshots your OpenClaw state before updates, runs the upgrade in a sandboxed dry-run against your live config, and auto-rolls back if any health check fails

OpenClaw ships updates every 2-3 days and each one risks breaking exec permissions, crashing the gateway, saturating CPU with plugin loading bugs, or silently deleting cron jobs. Four separate regressions in April 2026 alone (v2026.4.1 sandbox, v2026.4.5 CPU, v2026.4.14 memory timeouts, update command wiping Feishu and crons) hit thousands of self-hosters with no rollback path. The built-in openclaw doctor only validates config schema after the fact. This tool wraps the entire update lifecycle: snapshot state, dry-run the upgrade against your actual agent/cron/channel config, diff the before/after, and block or auto-rollback if anything regresses.
