feat: verify S244 @sungdark bounty — NO verdict, duplicate of S028

[xliry]

Issue: #204
Submission: #204 (comment)
Author: @sungdark

Problem (in our own words)

S244 claims that global mutable singleton state in registry.py (_RUNTIME), config.py, and runtime state modules makes parallel execution impossible and breaks test isolation.

Evidence

• base/registry.py:397: _RUNTIME = _RegistryRuntime(...) is a module-level mutable singleton — confirmed.
• base/registry.py:418-428: register_detector() mutates _RUNTIME directly — confirmed.
• base/config.py: No global mutable state exists. load_config(path) and save_config(config, path) are stateless functions with explicit parameters — claim refuted.
• base/registry.py:434-441: reset_registered_detectors() exists for test isolation, mitigating the concern.

Fix

No fix needed — verdict is NO.

Verdict

Question	Answer	Reasoning
Is this poor engineering?	YES	The _RUNTIME global mutable singleton in registry.py is a real pattern concern
Is this at least somewhat significant?	NO	Already identified and credited in S028; config.py claim is factually wrong

Final verdict: NO

Summary

The _RUNTIME global mutable singleton observation in registry.py is factually correct but duplicates S028 (@dayi1000), which was already credited for identifying the concrete stale-binding bug caused by this same global state. S181 made the identical "global state anti-pattern in registry" observation and was rejected as a duplicate. The config.py claim is factually incorrect — it has no global mutable state.

Why Desloppify Missed This

• What should catch: global_mutable_config detector
• Why not caught: The detector targets user codebases, not desloppify's own internals
• What could catch: Self-analysis mode or internal dogfooding scan
