[1.52.6] - 2026-07-01
Fixed
- --json now stays machine-readable on CLI errors. When an unknown flag or a bare usage error was hit together with --json, the CLI printed the human help text instead of JSON — so piping the output to a JSON parser (SysManager.exe --bogus --json | ConvertFrom-Json) broke. Both error paths now emit valid JSON: an unknown flag returns {"error": "..."} and a bare usage error returns the machine-readable command catalog.
- Headless CLI reports a runtime fault as an error (exit 1), not a usage error (exit 2). If a CLI command threw unexpectedly the process exited with code 2, which conventionally means "you typed the command wrong." An unexpected fault is now logged and exits with code 1 (general error), so scripts can distinguish a bad invocation from a genuine failure.
- Startup crashes are now logged instead of vanishing. The unhandled-exception handlers were registered after the dependency container, tray icon, and resource-history sampler were built — so a failure during that early startup surfaced as a bare Windows crash with no log entry. The handlers are now wired first, so any startup fault is captured in the log.
- Resource-history retention config load no longer risks an unhandled exception at startup. Reading the retention setting caught malformed JSON and I/O errors but not an access-denied error; since it runs during construction, that gap could throw in the unprotected startup window. It now degrades to the 7-day default on access-denied too.
