The finding · Class 7 · Temporal & Knowledge Boundary

Real context moved 0.0pp on Post-Cutoff Fabrication.

~intervals overlap — not separated from no change

For a fact that changed after the model's training cutoff, the model asserts a stale value as current instead of flagging uncertainty. The rule

never pooled · a trap ratio would skew the delta

Residual — what survives

Unchanged by context: 100% with none, 100% with the strongest supplied source. For a control mode that flat line is the result — it is what licenses reading movement elsewhere in this loop as grounding rather than as a document being present.
