SECONDARY CONDITIONS PROJECT ADD-ON

For each possible secondary condition, identify:
- already service-connected primary condition
- separate current condition or persistent symptoms
- possible causation or aggravation bridge
- medical records hinting at the link
- medications or altered body mechanics if relevant
- whether this is truly secondary or really an increased-rating issue on the primary condition

Do not use "everything is connected" logic. Build a real evidence bridge or mark the issue as not ready.
