1# Trace changed positions
2 
3This is the query a vault can answer that nothing else can, and the reason the
4supersession rules exist. It only works because contradictions are recorded
5rather than overwritten.
6 
7## Core rule
8 
9Report the change with both positions, both dates and the evidence between them.
10A conclusion without its history is just the current claim.
11 
12## Workflow
13 
141. **Find superseded claims** across concept pages, and contradictions where the
15   sources differ in date.
162. **Reconstruct the sequence:** what the page said, when, based on what; what
17   changed it, when.
183. **Distinguish real revision from correction.** A factual error being fixed is
19   not a change of mind. A conclusion being revised on better evidence is.
204. **Flag unresolved ones.** Contradictions still sitting open are the most
21   actionable output here.
225. **Say how firm the current position is,** based on what moved it.

24## Output format
25 
26```
27## <topic>
28Was: <claim> (<source>, <date>)
29Now: <claim> (<source>, <date>)
30What moved it: <evidence>
31Firmness: <what would move it again>
32 
33## Still unresolved
34<contradictions with no current position>
35```

37## Calibration
38 
39If nothing has changed in the period, say so in one line. Manufacturing an
40apparent revision from two pages that never disagreed is worse than an empty
41result.
42 
43Never present the more recent source as correct by virtue of being recent.
