`make rebuild` runs `compose build --no-cache backend gateway` plus a fresh `up -d --wait`. It must therefore also reap any engine container whose bind-mount source went away during host downtime, otherwise the new backend image boots into a stack with the same orphan that triggered the heal flow in the first place. Also extend the troubleshooting note: pulling the heal-cycle fix requires one explicit `make rebuild` so the backend image picks up the pre-bootstrap reconciler tick. Without that, `make up` runs the new Makefile target but the legacy backend cannot follow through, and the developer is left staring at a `cancelled` sandbox with no running replacement.
