# Legacy SIGNAL()/SLOT() connection syntax widely used

**Severity:** Low-Medium  
**Area:** Various  

## Description
Detected ~94 uses of old `SIGNAL()`/`SLOT()` syntax. While functional, this lacks compile-time checking and hampers modernization.

## Evidence
Automated scan found ~94 occurrences across the codebase.

## Steps to Reproduce
1. Grepped codebase for `connect(..., SIGNAL(` and `connect(..., SLOT(`.

## Expected Behavior
Use function-pointer (typed) `connect` syntax for compile-time safety and Qt6 best practices.

## Actual Behavior
Old macro-based syntax is still common.

## Suggested Fix / Next Steps
- Gradual refactor to typed connects, starting from central modules.
- Add CI check to prevent reintroduction.
