| # Syntax lint for the deploy/ daemon artifacts. | |
| # | |
| # These files are hand-written examples an operator adapts; nothing exercises them in the normal test | |
| # suite (deploy/** is not in any other workflow's path filter), so a typo'd directive or a malformed | |
| # plist ships silently and only fails on the operator's box. This workflow is the cheap gate: it checks | |
| # STRUCTURE, not runtime behaviour. | |
| # | |
| # - worker.service / receiver.service : `systemd-analyze verify` parses the units. The PLACEHOLDER | |
| # paths (/opt/pi-dispatch, /usr/bin/node) do not exist on the runner, so path-existence warnings are | |
| # EXPECTED and ignored; only genuine syntax errors (unknown directives, parse failures) fail. | |
| # - com.pi-dispatch.worker.plist : `xmllint --noout` proves the plist is well-formed XML. plutil is | |
| # macOS-only, so xmllint (libxml2-utils) is the Linux stand-in for well-formedness. | |
| # - worker-env-wrapper.sh : `sh -n` is a POSIX shell parse check (no execution). | |
| # | |
| # The `.cmd` wrappers (worker-env-wrapper.cmd, nssm-install.cmd) have no practical Linux linter and are | |
| # not checked here -- deliberately, rather than with a flaky approximation. | |
