Problem

The present threshold of 0.05 has expert evidence only at or below 0.05. Patterns stop gaining matches at different distances: SPEC at 0.05 to 0.075, REPO at 0.10, LAY at 0.125 to 0.15, HEX at 0.15 to 0.25. GATE does not stop by 0.30. Section 5 of docs/system-design-format/pattern-matching.md cannot change without labels, because a match that counts as present takes its misfits out of the ranking.

Observed

docs/system-design-format/proof/2026-11-04-distance-sweep.md holds the sweep for os-backlog and os-sdlc at commit 1d27db42.

Reproduce

n/a: this is an expert labeling run, not a defect.

Approach

Dump the filled matches with distance above 0.05 and at or below 0.15 from docs/system-design-format/proof/distance-sweep/gauge_dump.rb. An expert check labels each match as implemented or not implemented, with the same method as docs/system-design-format/proof/pattern-distance-run-3.md. The result says for each pattern whether a threshold above 0.05 beats 0.05.

Required work: none beyond the acceptance criteria.

Acceptance criteria

Given the 2026-11-04 sweep, when the run ends, then a proof file holds one expert label for each filled match with distance above 0.05 and at or below 0.15, in os-backlog and os-sdlc.
Given the labels, when the proof file is read, then it states for each pattern whether a threshold above 0.05 beats 0.05, with the confirmed count at each threshold.
