docs(decision): re-measure E-3 and fix the labels README's dead reference

Browse source 
E-3 with the calibrated lines: 66% at 95% precision with the text lane, 55% at
81% without, 2 false accepts against 8. The lane adds 11 pp of coverage while
raising precision 14 pp, so the answer stands and the margin is wider than the
audit's.

The labels README pointed at evidence/image6_v2.json, which was a byte-identical
duplicate of eval/labels/image6.json and is now removed; the README says so
instead of describing a copy that no longer exists.

It is not a veto-only lane.
Re-measured 2026-09-29 with the calibrated accept lines: 66% at 95% precision
with text, 55% at 81% without (2 false accepts against 8). The lane still adds
11 pp of coverage while raising precision by 14 pp, so the answer is unchanged
and the margin is wider than the audit's.
**E-2 answered.** `LocalLane` is RootSIFT-only; ORB and BRISK survive only in
the `matcher` baseline lane, so there is nothing to drop from the shipped path.

Tier-2 labels must add both. `confidence` is the labeler's own certainty for
that row; `labeler` names the person or pass that produced it, because Tier 2 is
double-labelled and a disagreement has to be traceable to a pass. Tier 1
(`image6_v2.json`) is dev-only and its numbers never ship, so it stays as it is.
