Individual skill
second-brain-changed-my-mind
Trace where the user's recorded position on something has shifted: superseded claims, contradictions between sources of different dates, and what evidence moved them. Use this skill when the user asks what they have changed their mind about, how their thinking on a topic developed, what they used to believe, or wants a quarterly look back at their own positions. Do NOT use for finding contradictions between sources with no time dimension, or for a current-state answer.

# Trace changed positions
This is the query a vault can answer that nothing else can, and the reason the
supersession rules exist. It only works because contradictions are recorded
rather than overwritten.
## Core rule
Report the change with both positions, both dates and the evidence between them.
A conclusion without its history is just the current claim.
## Workflow
1. **Find superseded claims** across concept pages, and contradictions where the
