upgrade is a hidden system workflow used by bunx smithers-orchestrator upgrade. It checks the installed Smithers version, fetches relevant changelog
entries, computes the package-manager-specific upgrade command, and asks a cheap
agent to perform the upgrade. If the cheap attempt cannot proceed safely, the
workflow escalates to the smart agent pool.
Run it explicitly when you want the durable workflow form:
needsHelp reason.
Like other system workflows, upgrade is hidden from default workflow listings
but remains available with workflow list --system and explicit
workflow run upgrade.
