Description
User feedback: v2 slide 08b is wrong; the metric should be about how far the average AFR/EUR/etc. point is from other points in the same population, i.e. within-population variation, not distance to a centroid.
Goal: replace the centroid/RMS-radius dispersion slide with a pairwise within-population distance metric.
Requirements:
- Discard the centroid-based metric for the main recommendation.
- Locate the MDS/PCoA coordinates and population labels used by the current MDS plot.
- Compute within-population pairwise distances in the displayed 2D MDS space, and if feasible also in higher-dimensional MDS coordinates as a sensitivity check.
- For each superpopulation, report mean pairwise distance, median pairwise distance, IQR/CI, n points, and number of pairs.
- Generate a clean plot: violin/box/dot distribution of pairwise distances by superpopulation, or a compact mean+CI plot. This should directly answer within-population variation.
- Include limitations: non-independent PHR flanks, unequal sample sizes, 2D projection vs full MDS dimensions.
- Keep outputs under slides/v2-review-zoom/_revision_assets/v3/08b_within_pop_pairwise/.
Validation:
- README defines the metric in one sentence.
- TSV of per-population summary and/or pairwise distances is written.
- Main candidate does not use centroid distance.

- 2026-05-07T01:09:25.214331929+00:00 Starting implementation: locating slide 08b source data and existing v2 centroid artifact.
- 2026-05-07T01:13:46.255198061+00:00 Implemented v3 pairwise-distance generator; running it to produce summary TSVs and candidate plots.
- 2026-05-07T01:17:40.271808598+00:00 Validated: R generator reruns cleanly; README defines same-superpopulation pairwise MDS D1-D2 metric; summary TSV reports mean, median, quartiles/IQR, sample-bootstrap CI, n points, and pair counts for 2D plus 5D sensitivity; v3 files contain no centroid/RMS/radius metric.
- 2026-05-07T01:17:40.385165057+00:00 Validated: no Cargo.toml at repo root, so cargo build/test are not applicable for this docs/R asset task; git diff --check passed.
