Thesis Change Tracker
See when the actions stop matching the old story.
A single filing move is a snapshot. A sequence can reveal a reversal, a sustained build, or a continued reduction. We label only the reported pattern—never an intent the filing cannot prove.

“Thesis change” describes a change in disclosed position behavior, not a claim about private reasoning. Strength reflects reversal, position stakes, move magnitude, and sequence depth; it is a research-priority rank, not a forecast.
