" summary

A tour of jhack shows concrete dev tools for Juju charms: jhack tail parses debug logs and replays event history; show-relation and stored-data viewers dump exact relation and charm store contents; jhack fire simulates events by populating real hook environment variables; sync pushes local file changes into a live unit for instant iteration; replay records hook-tool and Pebble interactions so executions can be replayed offline for repeatable postmortems and CI debugging.
