Static Lifecycle Scan

check-lifecycle is a dedicated Pro+ quality test (lifecycle_scan). It finds AST leak patterns at file:line. It does not measure RSS or OS threads — that stays Gist Factor.

Key points

• CLI: On Windows the examples use the recommended py -3.12 -m <module> ... form (for example py -3.12 -m manifestguard ...). On Linux/macOS this usually maps to python3.12 -m ....
• Community can read this guide and manifestguard list-tests. Running the scan requires Trial/Pro or higher.
• Detectors: list bloat, sync I/O, context managers, Thread without join, Timer without cancel, logger addHandler without a handlers guard, optional PyQt/PySide QThread.
• Not part of check --extended. Add check-lifecycle as its own CI gate when you want it.
• Default confidence is high. --min-confidence medium includes QThread. --all-findings shows weak LIST_BLOAT collectors.

Recommended mgpy workflow

1. py -3.12 -m manifestguard check-lifecycle
2. Join/track Thread teardown, cancel Timer on stop, guard addHandler with if not logger.handlers.
3. For PyQt/PySide, call quit()/wait() in the same class as QThread.start.
4. Keep quality CI on check --extended --refactor --verbose as a separate command.

Quick start

py -3.12 -m manifestguard list-tests
py -3.12 -m manifestguard check-lifecycle
py -3.12 -m manifestguard check-lifecycle --min-confidence medium
py -3.12 -m manifestguard check --extended --refactor --verbose
