The diagnostics message no longer carries the absolute path, the restore test
closes its raw sqlite connections before the live file is replaced, the logs
tests declare their own folder_paths base directory, and the isolated logger
filters every handler to the test thread.
* fix: diagnostics, backup, and restore now respect config.json db path (#132)
* test: add regression tests for config-aware diagnostics and backup (#132)
* fix(test): use fresh event loop to avoid aiohttp test pollution
* fix: don't kill singleton image monitor when node instance is garbage collected
The __del__ method was calling stop_monitoring() on the shared singleton
ImageMonitor, killing it for ALL nodes whenever any single node instance
was garbage collected between workflow runs. This caused the monitor to
restart on every execution and miss image save events due to race conditions.
* test: add regression tests for image monitor singleton lifecycle
Ensures cleanup/del never stops the shared monitor, singleton is
thread-safe, and observer survives across node instance lifecycles.
* style: address PR review — log suppressed exceptions, remove unused imports
